August 1, 1996
 
Dear Shareholder,
    As you may be aware, an agreement
was reached in late June for VK/AC
Holding, Inc., the parent company of
Van Kampen American Capital, Inc., to
be acquired by the Morgan Stanley
Group Inc. While this announcement                        [PHOTO]              
may appear commonplace in an             DENNIS J. MCDONNELL AND DON G. POWELL 
ever-changing financial industry, we
believe it represents an exciting
opportunity for shareholders of our
investment products.
    With Morgan Stanley's global
leadership in investment banking and
asset management and Van Kampen American Capital's reputation for competitive
long-term performance and superior investor services, together we will offer a
broader range of investment opportunities and expertise.
    The new ownership will not affect our commitment to pursuing excellence in
all aspects of our business. And, we expect very little change in the way your
mutual fund account is maintained and serviced.
    A proxy will be mailed to you shortly explaining the acquisition and asking
for your vote of approval. Please read it carefully and return your response for
inclusion in the shareholder vote. We value our relationship with you and look
forward to communicating more details of this transaction, which is anticipated
to be completed in November.
 
ECONOMIC REVIEW AND OUTLOOK

    The economy demonstrated an acceleration in growth during the six-month
reporting period. After a nominal 0.3 percent growth rate in the last quarter of
1995, GDP (the nation's gross domestic product) rose by 2.0 percent in this
year's first quarter. And, as anticipated, the economy grew by 4.2 percent in
the second quarter, partly reflecting a recovery from the effects of labor
strikes earlier in the year and extreme weather conditions across the country.
Upward momentum has been assisted by consumer spending, as indicated by a 5.6
percent rise in retail sales in the first five months of this year versus the
comparable 1995 period.
    In the manufacturing sector, economic reports, such as the National
Association of Purchasing Managers Index, suggested a continued rebound in
production from last winter's lower levels. In June, this index reached its
highest level since early 1995. Strong levels of exports and a replenishing of
inventories have helped support this momentum.
    Surprisingly healthy economic activity led to concerns that inflation may
rise and the Federal Reserve Board might tighten monetary policy. Inflation
remains modest, however, with consumer prices rising at about a 3 percent annual
rate over the past year. Meanwhile, the closely watched "core" Consumer Price
Index, which excludes volatile food and energy components, has risen year over
year at rates between 2.7 and 3.0 percent per year, with mid-1996 readings at a
moderate 2.7 percent. In general, recent reports have suggested an upward creep
in labor-related costs, while indicating that prices of many commodities have
begun to decline.
 
                                                           Continued on page two
 
                                        1
<PAGE>   3
 
    We anticipate that reasonably strong economic growth will continue during
the balance of 1996, albeit at more moderate rates than the second quarter's
swift pace. While we expect rates of inflation to remain near current levels,
the Fed may begin to lean toward greater restraint in its monetary policy in the
coming months. That suggests an upward bias for short-term interest rates and
for yields on long-term bonds to remain steady at current levels. In particular,
we expect 10-year Treasury yields to trade within a range of 5.7 and 6.3
percent, particularly when compared to taxable investments.
 
MUNICIPAL MARKET REVIEW AND OUTLOOK
    We witnessed significant movement in municipal bond yields during the first
six months of 1996. Early in the period, the Fed lowered rates in order to
energize the economy, and bond prices increased. By late February, however, the
markets became concerned that the Fed could reverse its strategy direction and
raise rates. As a result, yields, as measured by the Bond Buyer 40 Municipal
Bond Index, rose from 5.6 percent to 6.0 percent during the period.
    We believe market conditions for municipal bonds are poised for improvement
in the second half of 1996. Three major factors contribute to our optimism:
- -  Near-term concerns about the implementation of a major tax reform have faded.
   In early 1996, the municipal market was wary of the growing political
   momentum for tax reform, which could have eroded the value of the market's
   tax-exempt status. However, the momentum slowed substantially and now appears
   to be on the back burner until after the 1996 presidential election. This has
   added stability to the market.
- -  For high-income households, tax-exempt bonds provide an attractive after-tax
    alternative. Municipal bond yields have elevated to a point where taxable
   equivalent yields range between 8.5 and 10 percent for investors in the 31
   percent tax bracket or higher.
- -  Recent volatility in the equity markets coupled with rising interest rates
   are leading individual investors, as well as institutions, to reexamine their
   allocation of assets. In general, this translates into an increased emphasis
   on fixed-income, which should lend support to the municipal market.
    Looking ahead, inflation fears and concerns about economic growth may
continue to influence the municipal bond market and fund performance results.
Nevertheless, we are optimistic that tax-exempt securities will produce
attractive results for investors during the remainder of 1996.

your continued confidence in your investment with Van Kampen American Capital.

                          PORTFOLIO MANAGEMENT REVIEW
            VAN KAMPEN AMERICAN CAPITAL INSURED TAX FREE INCOME FUND
 
We recently spoke with the management team of the Van Kampen American Capital
Insured Tax Free Income Fund about the key events and economic forces that
shaped the markets during the past six months. The team includes Joseph A.
Piraro, portfolio manager, and Peter W. Hegel, executive vice president for
fixed-income investments. The following excerpts reflect their views on the
Fund's performance during the six-month period ended June 30, 1996.
 
   Q
      WHAT EVENTS OR MARKET CONDITIONS HAD THE GREATEST IMPACT ON THE FUND
      DURING THE FIRST HALF OF THIS YEAR?
   A
      Early in the year, indicators pointing to a stronger, expanding economy
      sparked concern over inflation and expectations that the Federal Reserve
      Board would increase short-term interest rates in order to keep the
economy from overheating. The prospect of higher rates was a concern to the
market, which responded by trading toward lower prices and higher yields.
    On the other hand, municipal market concerns that major tax reform proposals
would gain acceptance--and potentially erode the tax-exempt status associated
with municipals--eased in the first half of 1996. So, even though bond prices
generally declined, they did so to a lesser extent in the municipal market.
 
   Q
      WHAT ACTIONS DID YOU TAKE TO ADJUST THE FUND'S PORTFOLIO?
   A
      We made a number of moves, such as building a higher cash position. We
      sold certain positions in order to establish some tax losses, with the
      idea of reinvesting the proceeds from these sales in higher-yielding
opportunities as they arise.
    Our focus has been on 15- to 20-year maturity bonds, with an emphasis on the
lower end of that range in order to help minimize portfolio volatility. We
believe the 15- to 20-year segment should provide the best relative value given
the current market environment. It also provides a high level of liquidity, due
to the broad base of investors seeking tax-exempt securities of this maturity,
such as insurance companies, mutual funds, and individuals.
    The duration of the Fund (a measure of the portfolio's sensitivity to
interest rate changes) is just slightly lower than the 8-year benchmark that we
try to target over time. Please refer to page four for Fund portfolio
highlights.
   Q
      HOW DID THE FUND PERFORM DURING THE PERIOD?
   A
      The Fund's total return (Class A shares at net asset value) over the
      six-month period ended June 30, 1996, was -1.65 percent(1). In comparison,
      the market return, as represented by the Lehman Brothers Municipal Bond
Index, was -0.45 percent for the same period. Longer term, the Fund generated a
one-year total return of 5.62 percent(1) (Class A shares at net asset value)
through June 30, 1996. The Lehman Index is a broad-based, unmanaged index of
municipal bonds and does not reflect any
 
                                        5
<PAGE>   7
 
commissions or fees that would be paid by an investor purchasing the securities
it represents. Please refer to the chart on page three for additional Fund
performance results.
    From an income perspective, the Fund's Class A shares ended the period with
an annualized dividend of $0.996 per share. The Fund's Board of Trustees
approved a reduction in the monthly dividend from $.0830 to $.0815 per share
(Class A shares), effective July 1, 1996. Based upon this reduced dividend
level, the Fund continues to provide a respectable level of tax-exempt income
with a distribution rate of 4.97 percent based on the maximum offering price as
of June 30, 1996--the equivalent of a 7.77 percent taxable distribution rate for
investors in the 36 percent federal income tax bracket.
   Q
      WHAT IS YOUR OUTLOOK FOR THE MARKET IN THE MONTHS AHEAD?
   A
      We expect to see continued low inflation, and the economy is likely to
      grow at a more moderate pace than the second quarter's swift pace. After
      sharp increases in the first half of 1996, we expect yields to remain in a
trading range around current levels.
    The supply of municipal securities in the marketplace should keep pace with
last year's volume, which was in the neighborhood of $165 billion. Higher
interest rates make municipal bonds more attractive, especially to investors in
the higher income tax brackets. A tax-free bond with a yield of six-plus percent
is the equivalent of a taxable bond with a 9-plus percent yield for investors in
the 36 percent tax bracket.
   Q
      HOW HAVE YOU POSITIONED THE PORTFOLIO AS WE MOVE INTO THE LAST HALF OF THE
      YEAR?
   A
      We expect to maintain emphasis on what we see as the more attractive
      sectors within the municipal market, such as essential services and
      housing. These sectors offer high liquidity, strong issuer backing, and
the added enhancement of insurance. In addition, housing issues provide high
yield with generally low volatility. We continue to maintain a position in
general obligation bonds, but believe that this sector is currently fully
priced.
    We continue to pursue a strategy of seeking a solid total return by
selecting issues that offer a competitive level of income, while looking for
opportunities to move into market sectors and specific issues that provide
opportunities for appreciation.

1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital Insured Tax Free Income Fund (the "Fund") is
organized as a series of Van Kampen American Capital Tax Free Trust (the
"Trust"), a Delaware business trust and is registered as a diversified open-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to provide investors with a high
level of current income exempt from federal income taxes, with liquidity and
safety of principal, primarily through an investment in a diversified portfolio
of insured municipal securities. The Fund commenced the distribution of its
Class B and Class C shares on May 1, 1993 and August 13, 1993, respectively. On
May 2, 1995, all Class D shareholders redeemed their shares and the class was
eliminated. The Fund will no longer offer Class D shares.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.

                           June 30, 1996 (Unaudited)
- --------------------------------------------------------------------------------
 
D. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of loss and offset such losses against any future realized capital gains.
At December 31, 1995, the Fund had an accumulated capital loss carryforward for
tax purposes of $5,502,403. Of this amount, $91,852, $17,995, $110,103,
$595,553, $319,218 and $4,367,682 will expire on December 31, 1996, 1997, 2000,
2001, 2002 and 2003, respectively.
 
E. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes.
 
F. INSURANCE EXPENSES--The Fund typically invests in insured bonds. Any
portfolio securities not specifically covered by a primary insurance policy are
insured secondarily through the Fund's portfolio insurance policy. Insurance
premiums are based on the daily balances of uninsured bonds in the portfolio of
investments and are charged to expense on an accrual basis. The insurance policy
guarantees the timely payment of principal and interest on the securities in the
Fund's portfolio.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen American
Capital Investment Advisory Corp. (the "Adviser") will provide investment advice
and facilities to the Fund for an annual fee payable monthly as follows:

its affiliates' (collectively "VKAC") cost of providing accounting, cash
management and legal services to the Fund.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the six months ended
June 30, 1996, the Fund recognized expenses of approximately $655,800,
representing ACCESS' cost of providing transfer agency and shareholder services
plus a profit.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.
 
    At June 30, 1996, VKAC owned 132 and 129 shares of Classes B and C,
respectively.
 
3. CAPITAL TRANSACTIONS
 
The Fund has outstanding three classes of common shares, Classes A, B and C,
each with a par value of $.01 per share. There are an unlimited number of shares
of each class authorized.
 
    At June 30, 1996, capital aggregated $1,240,841,104, $71,562,704 and
$4,851,223 for Classes A, B and C, respectively. For the six months ended June

    Class B and C shares are offered without a front end sales charge, but are
subject to a contingent deferred sales charge (CDSC). The CDSC will be imposed
on most redemptions made within six years of the purchase for Class B and one
year of the purchase for Class C as detailed in the following schedule. The
Class B and C shares bear the expense of their respective deferred sales
arrangements, including higher distribution and service fees and incremental
transfer agency costs.

    For the six months ended June 30, 1996, VKAC, as Distributor for the Fund,
received commissions on sales of the Fund's Class A shares of approximately
$252,500 and CDSC on redeemed shares of approximately $127,600. Sales charges do
not represent expenses of the Fund.
 
    On September 27, 1995, the Fund acquired all of the assets and liabilities
of the Van Kampen American Capital Tax-Exempt Trust-Insured Municipal Portfolio
(the "AC Fund"), through a tax free reorganization approved by AC Fund
shareholders on September 21, 1995. The Fund issued 3,513,425 Class A shares,
1,958,037 Class B shares and 73,421 Class C shares valued at $65,701,115,
$36,595,879 and $1,372,231, respectively, in exchange for AC Fund's net assets.
Shares issued in connection with this reorganization are included in common
share sales for the year ended December 31, 1995. Combined net assets on the
date of acquisition were $1,236,253,953.
 
4. INVESTMENT TRANSACTIONS
 
During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $535,106,776 and $595,257,653,
respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS
 
A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.
 
    The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in the unrealized
appreciation/depreciation on securities. Upon disposition, a realized gain or
loss is recognized accordingly, except for exercised option contracts where the
recognition of gain or loss is postponed until the disposal of the security
underlying the option contract.
 
    Summarized below are the specific types of derivative financial instruments
used by the Fund.
 
A. OPTION CONTRACTS--An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put) an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration.

B. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Bonds and the Municipal Bond
Index and typically closes the contract prior to the delivery date. These
contracts are generally used to manage the portfolio's effective maturity and
duration.
 
    Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin). The cost of securities acquired through
delivery under a contract is adjusted by the unrealized gain or loss on the
contract.
 
    Transactions in futures contracts, each with a par value of $100,000, for
the six months ended June 30, 1996, were as follows:

    An Inverse Floating security is one where the coupon is inversely indexed to
a short-term floating interest rate multiplied by a specified factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.
 
    An Embedded Swap security includes a swap component such that the fixed
coupon component of the underlying bond is adjusted by the difference between
the securities fixed swap rate and the floating swap index. These instruments
are typically used by the Fund to enhance the yield of the portfolio.
 
6. DISTRIBUTION AND SERVICE PLANS
 
The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940 and a service plan (collectively
the "Plans"). The Plans govern payments for the distribution of the Fund's
shares, ongoing shareholder services and maintenance of shareholder accounts.
 
    Annual fees under the Plans of up to .25% of Class A shares and 1.00% each
of Class B and Class C shares are accrued daily. Included in these fees for the
six months ended June 30, 1996, are payments to VKAC of approximately $355,500.

August 1, 1996
 
Dear Shareholder,
    As you may be aware, an agreement
was reached in late June for VK/AC
Holding, Inc., the parent company of
Van Kampen American Capital, Inc., to
be acquired by the Morgan Stanley
Group Inc. While this announcement                       [PHOTO]              
may appear commonplace in an             DENNIS J. MCDONNELL AND DON G. POWELL
ever-changing financial industry, we
believe it represents an exciting
opportunity for shareholders of our
investment products.
    With Morgan Stanley's global
leadership in investment banking and
asset management and Van Kampen American Capital's reputation for competitive
long-term performance and superior investor services, together we will offer a
broader range of investment opportunities and expertise.
    The new ownership will not affect our commitment to pursuing excellence in
all aspects of our business. And, we expect very little change in the way your
mutual fund account is maintained and serviced.
    A proxy will be mailed to you shortly explaining the acquisition and asking
for your vote of approval. Please read it carefully and return your response for
inclusion in the shareholder vote. We value our relationship with you and look
forward to communicating more details of this transaction, which is anticipated
to be completed in November.
 
ECONOMIC REVIEW AND OUTLOOK
    The economy demonstrated an acceleration in growth during the six-month
reporting period. After a nominal 0.3 percent growth rate in the last quarter of
1995, GDP (the nation's gross domestic product) rose by 2.0 percent in this
year's first quarter. And, as anticipated, the economy grew by 4.2 percent in
the second quarter, partly reflecting a recovery from the effects of labor
strikes earlier in the year and extreme weather conditions across the country.
Upward momentum has been assisted by consumer spending, as indicated by a 5.6
percent rise in retail sales in the first five months of this year versus the
comparable 1995 period.
    In the manufacturing sector, economic reports, such as the National
Association of Purchasing Managers Index, suggested a continued rebound in
production from last winter's lower levels. In June, this index reached its
highest level since early 1995. Strong levels of exports and a replenishing of
inventories have helped support this momentum.
    Surprisingly healthy economic activity led to concerns that inflation may
rise and the Federal Reserve Board might tighten monetary policy. Inflation
remains modest, however, with consumer prices rising at about a 3 percent annual
rate over the past year. Meanwhile, the closely watched "core" Consumer Price
Index, which excludes volatile food and energy components, has risen year over
year at rates between 2.7 and 3.0 percent per year, with mid-1996 readings at a
moderate 2.7 percent. In general, recent reports have suggested an upward creep
in labor-related costs, while indicating that prices of many commodities have
begun to decline.
 
                                                           Continued on page two
 
                                        1
<PAGE>   41
 
    We anticipate that reasonably strong economic growth will continue during
the balance of 1996, albeit at rates more moderate than the second quarter's
swift pace. While we expect rates of inflation to remain near current levels,
the Fed may begin to lean toward greater restraint in its monetary policy in the
coming months. That suggests an upward bias for short-term interest rates and
for yields on long-term bonds to remain steady at current levels. In particular,
we expect 10-year Treasury yields to trade within their current range of 5.7 and
6.3 percent, particularly when compared to taxable investments.
 
MUNICIPAL MARKET REVIEW AND OUTLOOK
    We witnessed significant movement in municipal bond yields during the first
six months of 1996. Early in the period, the Fed lowered rates in order to
energize the economy, and bond prices increased. By late February, however, the
markets became concerned that the Fed could reverse its strategy direction and
raise rates. As a result, yields, as measured by the Bond Buyer 40 Municipal
Bond Index, rose from 5.6 percent to 6.3 percent during the period.
    We believe market conditions for municipal bonds are poised for improvement
in the second half of 1996. Three major factors contribute to our optimism:
- -   Near-term concerns about the implementation of a major tax reform have
     faded. In early 1996, the municipal market was wary of the growing
     political momentum for tax reform, which could have eroded the value of the
     market's tax-exempt status. However, the momentum slowed substantially and
     now appears to be on the back burner until after the 1996 Presidential
     election. This has added stability to the market.
- -   For high-income households, tax-exempt bonds provide an attractive after-tax
     alternative. Municipal bond yields have elevated to a point where taxable
     equivalent yields range between 8.5 and 10 percent for investors in the 31
     percent tax bracket or higher.
- -   Recent volatility in the equity markets coupled with rising interest rates
     are leading individual investors, as well as institutions, to reexamine
     their allocation of assets. In general, this translates into an increased
     emphasis on fixed-income, which should lend support to the municipal
     market.
    Looking ahead, inflation fears and concerns about economic growth may
continue to influence the municipal bond market and fund performance results.
Nevertheless, we are optimistic that tax-exempt securities will produce
attractive results for investors during the remainder of 1996.

your continued confidence in your investment with Van Kampen American Capital.

                          PORTFOLIO MANAGEMENT REVIEW
             VAN KAMPEN AMERICAN CAPITAL TAX FREE HIGH INCOME FUND
 
We recently spoke with the management team of the Van Kampen American Capital
Tax Free High Income Fund about the key events and economic forces that shaped
the markets during the first half of the Fund's fiscal year. The team includes
David C. Johnson, portfolio manager, and Peter W. Hegel, executive vice
president for fixed-income investments. The following excerpts reflect their
views on the Fund's performance during the six-month period ended June 30, 1996.

   Q  THE MUNICIPAL BOND MARKET EXPERIENCED SOME FLUCTUATIONS DURING THE FIRST
      SIX MONTHS OF 1996. COULD YOU EXPLAIN WHAT HAPPENED IN THE MARKET DURING
      THIS PERIOD AND WHAT FACTORS PLAYED THE GREATEST ROLE?

   A  We did see some significant price fluctuations in the municipal bond
      market during the first half of the year. January was the only period that
      enjoyed the same positive investment environment that dominated the bond
market through most of 1995. In contrast, February brought an abrupt end to the
increase in bond prices, and this environment continued throughout the rest of
the reporting period. Instead of anticipating further interest rate reductions,
the market grew wary that interest rates might be increased (tightened) by the
Federal Reserve Board. This concern was triggered by two main factors:
- -    The federal government was shut down twice, which indicated that balanced
     budget legislation was not imminent.
- -    Several economic indicators pointed to accelerating economic growth.
     Consecutive monthly employment reports showed significant increases in
     employment. For example, 239,000 non-farm jobs were added to the economy in
     June.
    These factors led to fears that inflation, which had been holding steady
around 3 percent, might increase. Fears heightened when agricultural commodity
and oil prices rose to their highest levels in two years. As a result, the Fed
shifted policy from an accommodative mode (lowering interest rates) in January
to a stable, or neutral, mode. Thereafter, bond prices generally began to
decrease.

   Q  HOW WAS THE FUND STRUCTURED OVER THE LAST SIX MONTHS?

   A  The Fund is managed to seek to provide both an attractive tax-exempt yield
      and a relatively stable net asset value. A fair percentage of the Fund's
      holdings are investment-grade bonds (BBB-rated or higher), with 30.5
percent rated single-A or higher. As of June 30, 1996, more than 40 percent of
the Fund was invested in non-rated securities and those rated below
investment-grade. By utilizing both kinds of issues, we are able to position the
Fund defensively against bond price fluctuations. This is because values of
non-rated and lower-rated securities are less dependent on interest rates and
more dependent on credit quality considerations. In contrast, the values of
higher-rated securities are more responsive to changes in interest rates, but
these securities incur less credit risk.
 
                                        5
<PAGE>   45
 
    Over the past six months, the Fund's duration stood at approximately 8
years. Duration is a measurement of a portfolio's sensitivity to changes in
interest rates--the shorter the duration, the less sensitive the portfolio is
expected to be to interest rate movements. The Fund's 8-year duration is
consistent with major municipal bond indices and is a level that allows us to
achieve a balance between maintaining an attractive dividend and protecting the
portfolio against diverse market changes.
    We continue to see value in 15- to 20-year maturities. Acquisitions in the
Fund have emphasized this maturity range, which we believe offers the best
relative value compared to Treasury yields at this time, with less price
volatility than is usually associated with long-term maturities. Please refer to
page four for Fund portfolio highlights.
 
   
   Q  WERE THERE OTHER FACTORS THAT INFLUENCED THE MUNICIPAL BOND MARKET OVER
      THE LAST SIX MONTHS?
   
   A  The supply and demand relationship continued to be a positive influence on
      the municipal bond market over the reporting period--supply remained low
      while demand remained fairly strong. This helped support bond prices and
partly offset the negative effect that rising interest rates had on bond prices.
    Another influence was the role that potential major tax reform played on
municpal bonds. The market's initial reaction to this issue was negative,
because major reform may remove the tax advantage municipal bonds now offer. We
believe the market has now discounted the potential impact of tax reform, and we
do not expect any type of reform to be implemented until 1997, at the earliest.
However, this issue may continue to receive media coverage throughout the
remainder of 1996, primarily near the presidential election in November, and we
will continue to monitor it closely for any developments.
 
   
   Q  WHAT WERE THE MOST ATTRACTIVE SECTORS FOR THE FUND?
   
   A  We continued to find value in a wide array of sectors and individual
      issues across many categories for both investment and non-investment grade
      acquisitions. One sector that continues to remain attractive is healthcare
and its related areas. Because we have dedicated analysts who specialize in
thoroughly researching each sector, we continue to find issues offering the
greatest relative value. Recently, the housing sector has also provided some
attractive holdings for the Fund.
   
   Q  HOW DID THE FUND PERFORM DURING THE SIX MONTHS ENDED JUNE 30, 1996?
   
   A  For the six months ended June 30, 1996, the Fund's total return was -1.06
      percent(1) (Class A shares at net asset value). By comparison, the Lehman
Brothers Municipal Bond Index earned a total return of -0.45 percent over the
same period. Longer term, the Fund generated a one-year total return of 6.04
percent(1) (Class A shares at net asset value) through June 30, 1996. The Lehman
Index is a broad-based, unmanaged index of municipal bonds and does not reflect
any commissions or fees that would be paid by an investor purchasing the
securities it represents. Please refer to the chart on page three for additional
Fund performance results.

    At its current annualized dividend level of $0.96 per share, the Fund
provides shareholders with a tax-free distribution rate of 6.37 percent(3)
(Class A shares) as of June 30, 1996. At this distribution rate, the Fund
provides shareholders in the 36 percent federal income tax bracket with a yield
equivalent to a taxable investment earning 9.95 percent(4).
 
   Q
      WHAT IS YOUR OUTLOOK FOR THE MUNICIPAL BOND MARKET IN THE UPCOMING MONTHS,
      AND WHAT FACTORS COULD INFLUENCE YOUR MANAGEMENT OF THE FUND?
   A
      The municipal market should remain stable over the next few months,
      especially if the current market fundamentals--including low inflation and
      a positive supply and demand ratio--remain in place. We do not anticipate
any significant changes in the management of the Fund. However, if the economy
continues to show signs of strong growth, we could see some changes in market
fundamentals:
- -   INFLATION has been holding at a low 2 to 3 percent range for some time now,
    but going forward, there is some concern that inflation could slowly creep
    upward, which could have a negative effect on the market.
- -   INTEREST RATES: We anticipate the Federal Reserve will remain in a neutral
    policy mode, but it may become necessary to tighten interest rates if the
    economy continues to strengthen. However, the Fund is structured defensively
    against such increases with its high-yielding, non-rated holdings.
- -   The positive ratio between LOWER SUPPLY AND HIGHER DEMAND should continue in
    the upcoming months, which is a stabilizing influence on municipal bond
    values. If there is a rally in bond prices, we could see an increase in
    refundings, which could bring more supply into the market.

1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital Tax Free High Income Fund (the "Fund") is organized
as a series of the Van Kampen American Capital Tax Free Trust, a Delaware
business trust, and is registered as a diversified open-end management
investment company under the Investment Company Act of 1940, as amended. The
Fund's investment objective is to provide investors with a high level of current
income exempt from federal income taxes primarily through investment in a
diversified portfolio of medium and lower grade municipal securities. The Fund
commenced investment operations on June 28, 1985. The distribution of the Fund's
Class B and Class C shares commenced on May 1, 1993 and August 13, 1993,
respectively. On July 7, 1995, all Class D shareholders redeemed their shares
and the class was eliminated. The Fund will no longer offer Class D shares.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Investments
valued using estimates of market value are generally those non-rated securities
in which the Fund owns over 90% of the original bond issue. At June 30, 1996,
19% of the Fund's net assets consisted of such securities. Short-term securities
with remaining maturities of less than 60 days are valued at amortized cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.

                           June 30, 1996 (Unaudited)
- --------------------------------------------------------------------------------
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.
 
D. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1995, the Fund had an accumulated capital loss
carryforward for tax purposes of $73,224,534. Of this amount, $1,295,852,
$42,680,935 and $29,247,747 will expire on December 31, 1999, 2002 and 2003,
respectively. Net realized gains or losses may differ for financial and tax
reporting purposes primarily as a result of the deferral of post October 31
losses and the capitalization of reorganization and restructuring costs for tax
purposes.
 
E. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Due to inherent differences in the recognition of interest
income under generally accepted accounting principles and federal income tax
purposes, for those securities which the Fund has placed on non-accrual status,
the amount of distributable net investment income may differ between book and
federal income tax purposes for a particular period. These differences are
temporary in nature, but may result in book basis distributions in excess of net
investment income for certain periods.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
 
Under the terms of the Fund's Investment Advisory Agreement, Van Kampen American
Capital Investment Advisory Corp. (the "Adviser") will provide investment advice
and facilities to the Fund for an annual fee payable monthly as follows:

Meagher & Flom, counsel to the Fund, of which a trustee of the Fund is an
affiliated person.
 
    For the six months ended June 30, 1996, the Fund recognized expenses of
approximately $43,300 representing Van Kampen American Capital Distributors,
Inc.'s or its affiliates' (collectively "VKAC") cost of providing accounting,
cash management and legal services to the Fund.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the six months ended
June 30, 1996, the Fund recognized expenses of approximately $359,400,
representing ACCESS' cost of providing transfer agency and shareholder services
plus a profit.
 
    Additionally, for the six months ended June 30, 1996, the Fund reimbursed
VKAC approximately $92,500 related to the cost of consolidating the VKAC
open-end fund complex. The reimbursement represents savings realized by the Fund
as a result of the consolidation.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.
 
    At June 30, 1996, VKAC owned 100 shares each of Classes B and C.

    For the six months ended June 30, 1996, VKAC, as distributor for the Fund,
received commissions on sales of the Fund's Class A shares of approximately
$182,700 and CDSC on redeemed shares of approximately $276,100. Sales charges do
not represent expenses of the Fund.
 
4. INVESTMENT TRANSACTIONS
 
During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments and reorganization and restructuring costs,
were $259,888,090 and $241,234,329, respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS
 
A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.
 
    The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in the unrealized
appreciation/depreciation on investments. Upon disposition, a realized gain or
loss is recognized accordingly, except for exercised option contracts where the
recognition of gain or loss is postponed until the disposal of the security
underlying the option contract.
 
    Summarized below are the specific types of derivative financial instruments
used by the Fund.

- --------------------------------------------------------------------------------
 
A. OPTION CONTRACTS--An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put) an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration.
 
    Transactions in options for the six months ended June 30, 1996, were as
follows:

</TABLE>
 
B. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Bonds and the Municipal Bond
Index and typically closes the contract prior to the delivery date. These
contracts are generally used to manage the portfolio's effective maturity and
duration.
 
    Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin). The cost of securities acquired through
delivery under a contract is adjusted by the unrealized gain or loss on the
contract.
 
    Transactions in futures contracts for the six months ended June 30, 1996,
were as follows:

C. INDEXED SECURITIES--These instruments are identified in the portfolio of
investments. The price of these securities may be more volatile than the price
of a comparable fixed rate security.
 
    An Inverse Floating security is one where the coupon is inversely indexed to
a short-term floating interest rate multiplied by a specified factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.
 
    An Embedded Swap security includes a swap component such that the fixed
coupon component of the underlying bond is adjusted by the difference between
the security's fixed swap rate and the floating swap index. These instruments
are typically used by the Fund to enhance the yield of the portfolio.
 
6. DISTRIBUTION AND SERVICE PLANS
 
The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940 and a service plan (collectively
the "Plans"). The Plans govern payments for the distribution of the Fund's
shares, ongoing shareholder services and maintenance of shareholder accounts.
 
    Annual fees under the Plans of up to .25% for Class A shares and 1.00% each
for Class B and Class C shares are accrued daily. Included in these fees for the
six months ended June 30, 1996 are payments to VKAC of approximately $556,700.

Dear Shareholder,
    As you may be aware, an agreement
was reached in late June for VK/AC
Holding, Inc., the parent company of
Van Kampen American Capital, Inc., to
be acquired by the Morgan Stanley
Group Inc. While this announcement                          [PHOTO]            
may appear commonplace in an              DENNIS J. MCDONNELL AND DON G. POWELL
ever-changing financial industry, we
believe it represents an exciting
opportunity for shareholders of our
investment products.
    With Morgan Stanley's global
leadership in investment banking and
asset management and Van Kampen
American Capital's reputation for competitive long-term performance and superior
investor services, together we will offer a broader range of investment
opportunities and expertise.
    The new ownership will not affect our commitment to pursuing excellence in
all aspects of our business. And, we expect very little change in the way your
mutual fund account is maintained and serviced.
    A proxy will be mailed to you shortly explaining the acquisition and asking
for your vote of approval. Please read it carefully and return your response for
inclusion in the shareholder vote. We value our relationship with you and look
forward to communicating more details of this transaction, which is anticipated
to be completed in November.
 
ECONOMIC REVIEW AND OUTLOOK

    The economy demonstrated an acceleration in growth during the six-month
reporting period. After a nominal 0.3 percent growth rate in the last quarter of
1995, GDP (the nation's gross domestic product) rose by 2.0 percent in this
year's first quarter. And, as anticipated, the economy grew by 4.2 percent in
the second quarter, partly reflecting a recovery from the effects of labor
strikes earlier in the year and extreme weather conditions across the country.
Upward momentum has been assisted by consumer spending, as indicated by a 5.6
percent rise in retail sales in the first five months of this year versus the
comparable 1995 period.
    In the manufacturing sector, economic reports, such as the National
Association of Purchasing Managers Index, suggested a continued rebound in
production from last winter's lower levels. In June, this index reached its
highest level since early 1995. Strong levels of exports and a replenishing of
inventories have helped support this momentum.
    Surprisingly healthy economic activity led to concerns that inflation may
rise and the Federal Reserve Board might tighten monetary policy. Inflation
remains modest, however, with consumer prices rising at about a 3 percent annual
rate over the past year. Meanwhile, the closely watched "core" Consumer Price
Index, which excludes volatile food and energy components, has risen year over
year at rates between 2.7 and 3.0 percent per year, with mid-1996 readings at a
moderate 2.7 percent. In general, recent reports have suggested an upward creep
in labor-related costs, while indicating that prices of many commodities have
begun to decline.
    We anticipate that reasonably strong economic growth will continue during
the balance of 1996, albeit at rates more moderate than the second quarter's
swift pace. While we expect rates of inflation to remain near current levels,

upward bias for short-term interest rates and for yields on long-term bonds to
remain steady at current levels. In particular, we expect 10-year Treasury
yields to trade within a range of 5.7 and 6.3 percent, particularly when
compared to taxable investments.
 
MUNICIPAL MARKET REVIEW AND OUTLOOK
    We witnessed significant movement in municipal bond yields during the first
six months of 1996. Early in the period, the Fed lowered rates in order to
energize the economy, and bond prices increased. By late February, however, the
markets became concerned that the Fed could reverse its strategy direction and
raise rates. As a result, yields, as measured by the Bond Buyer 40 Municipal
Bond Index, rose from 5.6 percent to 6.0 percent during the period.
    We believe market conditions for municipal bonds are poised for improvement
in the second half of 1996. Three major factors contribute to our optimism:
- -   Near-term concerns about the implementation of a major tax reform have
     faded. In early 1996, the municipal market was wary of the growing
     political momentum for tax reform, which could have eroded the value of the
     market's tax-exempt status. However, the momentum slowed substantially and
     now appears to be on the back burner until after the 1996 presidential
     election. This has added stability to the market.
- -   For high-income households, tax-exempt bonds provide an attractive after-tax
     alternative. Municipal bond yields have elevated to a point where taxable
     equivalent yields range between 8.5 and 10 percent for investors in the 31
     percent tax bracket or higher.
- -   Recent volatility in the equity markets coupled with rising interest rates
     are leading individual investors, as well as institutions, to reexamine
     their allocation of assets. In general, this translates into an increased
     emphasis on fixed-income, which should lend support to the municipal
     market.
    Looking ahead, inflation fears and concerns about economic growth may
continue to influence the municipal bond market and fund performance results.
Nevertheless, we are optimistic that tax-exempt securities will produce
attractive results for investors during the remainder of 1996.

                          PORTFOLIO MANAGEMENT REVIEW
          VAN KAMPEN AMERICAN CAPITAL CALIFORNIA INSURED TAX FREE FUND
 
We recently spoke with the management team of the Van Kampen American Capital
California Insured Tax Free Fund about the key events and economic forces that
shaped the markets during the first half of the Fund's fiscal year. The team
includes Joseph A. Piraro, portfolio manager, and Peter W. Hegel, executive vice
president for fixed-income investments. The following excerpts reflect their
views on the Fund's performance during the six-month period ended June 30, 1996.
     
   Q  WHAT EVENTS OR MARKET CONDITIONS HAD THE GREATEST IMPACT ON THE FUND
      DURING THE FIRST HALF OF THIS YEAR?
    
   A  Early in the year, indicators pointing to a stronger, expanding economy
      sparked concern over inflation and expectations that the Federal Reserve
      Board would increase short-term interest rates in order to keep the
economy from overheating. The prospect of higher rates was a concern to the
market, which responded by trading toward lower prices and higher yields.
    On the other hand, municipal market concerns that major tax reform proposals
would gain acceptance--and potentially erode the tax-exempt status associated
with municipals--eased in the first half of 1996. So, even though bond prices
generally declined, they did so to a lesser extent in the municipal market.
    
   Q  WHAT ACTIONS DID YOU TAKE TO ADJUST THE FUND'S PORTFOLIO?
   
   A  The Fund is structured with a duration of approximately 8 years. Duration
      is a measure of a portfolio's sensitivity to changes in interest rates.
      The shorter the duration, the less sensitive the portfolio is expected to
be to interest rates.
    Our focus has been on 15- to 20-year maturity bonds. We have tended to
emphasize the lower end of that range in order to help minimize overall
portfolio volatility. We believe the 15- to 20-year segment provided the best
relative value given the market conditions experienced in the first half of the
year. It also provides a high level of liquidity, due to the broad base of
investors seeking tax-exempt securities of this maturity, such as insurance
companies, mutual funds, and individuals. Please refer to page four for Fund
portfolio highlights.
    
   Q  HOW DID THE FUND PERFORM DURING THE PERIOD?
   
   A  The Fund's total return (Class A shares at net asset value) over the
      six-month period ended June 30, 1996, was -1.38 percent(1). In comparison,
      the market return, as represented by the Lehman Brothers Municipal Bond
Index, was -0.45 percent for the same period. Longer term, the Fund generated a
one-year total return of 6.52 percent(1) (Class A shares at net asset value)
through June 30, 1996. The Lehman Index is a broad-based, unmanaged index of
municipal bonds and does not reflect any commissions or fees that would be paid
by an investor purchasing the securities it represents. Please refer to the
chart on page three for additional Fund
performance results.
 
                                      5
<PAGE>   82
 
    From an income standpoint, the Fund's Class A shares ended the period with
an annualized dividend of $0.852 per share. The Fund's Board of Trustees
approved a reduction in the monthly dividend from $.0710 to $.0695 per share
(Class A shares), effective July 1, 1996. Based upon this reduced dividend
level, the Fund continues to provide a respectable level of tax-exempt income
with a distribution rate of 4.73 percent based on the maximum offering price as
of June 30, 1996--the equivalent of a 8.30 percent taxable distribution rate for
investors in the 43 percent combined federal and state income tax bracket.

   Q  WHAT IS YOUR OUTLOOK FOR THE MARKET IN THE MONTHS AHEAD?

   A  We expect to see continued low inflation, and the economy is likely to
      grow at a more moderate pace than the second quarter's swift pace. After
      sharp increases in the first half of 1996, we expect yields to remain in a
trading range around current levels.
    The California market once again led the nation in new issuance last year,
and the supply of California municipal bonds in the marketplace should keep pace
with last year's volume. The demand for insured municipals* continues to be very
strong, partly in response to last year's Orange County situation. In fact, more
than 50 percent of all California municipal bonds are now issued as insured
bonds, up from about 38 percent two years ago. We are investing in a sector with
good supply and strong demand, which bodes well for the Fund.

   Q  HOW HAVE YOU POSITIONED THE PORTFOLIO AS WE MOVE INTO THE LAST HALF OF THE
      YEAR?

   A  We expect to maintain our emphasis on what we see as the more attractive
      sectors within the municipal market, such as essential services and
      housing. These sectors offer high liquidity, strong issuer backing, and
the added enhancement of insurance. In addition, housing issues have
historically provided high yield with generally low volatility. We continue to
maintain our position in general obligation bonds, believing that this sector is
currently fully priced.
    California's economy has improved greatly, with most sectors recovering from
their depressed levels of two to three years ago. The state was number one in
the nation in job creation last year, driven by a recovery in the
defense/aerospace and entertainment / tourism industries. The real estate sector
has not bounced back fully, but remains relatively stable. We believe that the
state's general obligation bonds may be upgraded by the major rating agencies in
the future.

* The terms of the insurance are more fully described in the prospectus, and no
  representation is made as to the insurer's ability to meet its commitments. In
  addition, the insurance does not remove market risk since it does not apply to
  the securities in the Fund's portfolio, and the Fund's net asset value may
  increase or decrease depending on changes in interest rates and other factors
  affecting the municipal credit markets.

1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital California Insured Tax Free Fund (the "Fund") is
organized as a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust, and is registered as a diversified open-end management
investment company under the Investment Company Act of 1940, as amended. The
Fund's investment objective is to provide California investors with a high level
of current income exempt from federal and California income taxes, with
liquidity and safety of principal, primarily through investment in a diversified
portfolio of insured California municipal securities. The Fund commenced
investment operations on December 13, 1985. The distribution of the Fund's Class
B shares and Class C shares commenced on May 1, 1993, and August 13, 1993,
respectively.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.

                           June 30, 1996 (Unaudited)
- --------------------------------------------------------------------------------
 
D. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income, if any, to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the Federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1995, the Fund had an accumulated capital loss
carryforward for tax purposes of $7,345,503. Of this amount, $1,014,876,
$105,997, $5,623,922 and $600,708 will expire on December 31, 1996, 2001, 2002
and 2003, respectively. Net realized gains or losses may differ for financial
and tax reporting purposes primarily as a result of post October 31 losses which
are not recognized for tax purposes until the first day of the following fiscal
year.
 
E. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually.
 
F. INSURANCE EXPENSE--The Fund typically invests in insured bonds. Any portfolio
securities not specifically covered by a primary insurance policy are insured
secondarily through the Fund's portfolio insurance policy. Insurance premiums
are based on the daily balances of uninsured bonds in the portfolio of
investments and are charged to expense on an accrual basis. The insurance policy
guarantees the timely payment of principal and interest on the securities in the
Fund's portfolio.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, Van Kampen American
Capital Investment Advisory Corp. (the "Adviser") will provide investment advice
and facilities to the Fund for an annual fee payable monthly as follows:

- --------------------------------------------------------------------------------
 
    For the six months ended June 30, 1996, the Fund recognized expenses of
approximately $13,300 representing Van Kampen American Capital Distributors,
Inc.'s or its affiliates' (collectively "VKAC") cost of providing accounting,
cash management and legal services to the Fund.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the six months ended
June 30, 1996, the Fund recognized expenses of approximately $65,900,
representing ACCESS' cost of providing transfer agency and shareholder services
plus a profit.
 
    Additionally, for the six months ended June 30, 1996, the Fund reimbursed
VKAC approximately $32,400 related to the cost of consolidating the VKAC
open-end fund complex. The reimbursement represents savings realized by the Fund
as a result of the consolidation.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.
 
    At June 30, 1996, VKAC owned 100 shares each of Classes B and C.
 
3. CAPITAL TRANSACTIONS
 
The Fund has outstanding three classes of common shares, Classes A, B and C each
with a par value of $.01 per share. There are an unlimited number of shares of
each class authorized.

Class B and C shares bear the expense of their respective deferred sales
arrangements, including higher distribution and service fees and incremental

    For the six months ended June 30, 1996, VKAC, as Distributor for the Fund,
received commissions on sales of the Fund's Class A shares of approximately
$7,300 and CDSC on redeemed shares of approximately $19,200. Sales charges do

4. INVESTMENT TRANSACTIONS
 
During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $26,248,684 and $26,307,562,
respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS
 
A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.
 
    The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in the unrealized
appreciation/depreciation on securities. Upon disposition, a realized gain or
loss is recognized accordingly.
 
    Summarized below are the specific types of derivative financial instruments
used by the Fund.
 
A. OPTION CONTRACTS--An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put) an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration.
 
    Transactions in options for the six months ended June 30, 1996 were as
follows:

</TABLE>
 
B. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Bonds and the Municipal Bond
Index and typically closes the contract prior to the delivery date. These
contracts are generally used to manage the portfolio's effective maturity and
duration.

                           June 30, 1996 (Unaudited)
- --------------------------------------------------------------------------------
 
    Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin). The cost of securities acquired through
delivery under a contract is adjusted by the unrealized gain or loss on the
contract.
 
    Transactions in futures contracts, each with a par value of $100,000, for
the six months ended June 30, 1996, were as follows:

investments. The price of these securities may be more volatile than the price
of a comparable fixed rate security.
 
    An Inverse Floating security is one where the coupon is inversely indexed to
a short-term floating interest rate multiplied by a specified factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.
 
    An Embedded Swap security includes a swap component such that the fixed
coupon component of the underlying bond is adjusted by the difference between
the securities fixed swap rate and the floating swap index. These instruments
are typically used by the Fund to enhance the yield of the portfolio.
 
6. DISTRIBUTION AND SERVICE PLANS
 
The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940 and a service plan (collectively
the "Plans"). The Plans govern payments for the distribution of the Fund's
shares, ongoing shareholder services and maintenance of shareholder accounts.
 
    Annual fees under the Plans of up to .25% of Class A shares and 1.00% each
of Class B and Class C shares are accrued daily. Included in these fees for the
six months ended June 30, 1996, are payments to VKAC of approximately $100,400.

August 1, 1996
 
Dear Shareholder,
    As you may be aware, an agreement
was reached in late June for VK/AC
Holding, Inc., the parent company of
Van Kampen American Capital, Inc., to
be acquired by the Morgan Stanley                          [PHOTO]             
Group Inc. While this announcement        DENNIS J. MCDONNELL AND DON G. POWELL
may appear commonplace in an
ever-changing financial industry, we
believe it represents an exciting
opportunity for shareholders of our
investment products.
    With Morgan Stanley's global
leadership in investment banking and asset management and Van Kampen American
Capital's reputation for competitive long-term performance and superior investor
services, together we will offer a broader range of investment opportunities and
expertise.
    The new ownership will not affect our commitment to pursuing excellence in
all aspects of our business. And, we expect very little change in the way your
mutual fund account is maintained and serviced.
    A proxy will be mailed to you shortly explaining the acquisition and asking
for your vote of approval. Please read it carefully and return your response for
inclusion in the shareholder vote. We value our relationship with you and look
forward to communicating more details of this transaction, which is anticipated
to be completed in November.
 
ECONOMIC REVIEW AND OUTLOOK
    The economy demonstrated an acceleration in growth during the six-month
reporting period. After a nominal 0.3 percent growth rate in the last quarter of
1995, GDP (the nation's gross domestic product) rose by 2.0 percent in this
year's first quarter. And, as anticipated, the economy grew by 4.2 percent in
the second quarter, partly reflecting a recovery from the effects of labor
strikes earlier in the year and extreme weather conditions across the country.
Upward momentum has been assisted by consumer spending, as indicated by a 5.6
percent rise in retail sales in the first five months of this year versus the
comparable 1995 period.
    In the manufacturing sector, economic reports, such as the National
Association of Purchasing Managers Index, suggested a continued rebound in
production from last winter's lower levels. In June, this index reached its
highest level since early 1995. Strong levels of exports and a replenishing of
inventories have helped support this momentum.
    Surprisingly healthy economic activity led to concerns that inflation may
rise and the Federal Reserve Board might tighten monetary policy. Inflation
remains modest, however, with consumer prices rising at about a 3 percent annual
rate over the past year. Meanwhile, the closely watched "core" Consumer Price
Index, which excludes volatile food and energy components, has risen year over
year at rates between 2.7 and 3.0 percent per year, with mid-1996 readings at a
moderate 2.7 percent. In general, recent reports have suggested an upward creep
in labor-related costs, while indicating that prices of many commodities have
begun to decline.
 
                                                           Continued on page two
 
                                        1
<PAGE>   103
 
    We anticipate that reasonably strong economic growth will continue during
the balance of 1996, albeit at rates more moderate than the second quarter's
swift pace. While we expect rates of inflation to remain near current levels,
the Fed may begin to lean toward greater restraint in its monetary policy in the
coming months. That suggests an upward bias for short-term interest rates and
for yields on long-term bonds to remain steady at current levels. In particular,
we expect 10-year Treasury yields to trade within a range of 5.7 and 6.3
percent, particularly when compared to taxable investments.
 
MUNICIPAL MARKET REVIEW AND OUTLOOK
    We witnessed significant movement in municipal bond yields during the first
six months of 1996. Early in the period, the Fed lowered rates in order to
energize the economy, and bond prices increased. By late February, however, the
markets became concerned that the Fed could reverse its strategy direction and
raise rates. As a result, yields, as measured by the Bond Buyer 40 Municipal
Bond Index, rose from 5.6 percent to 6.0 percent during the period.
    We believe market conditions for municipal bonds are poised for improvement
in the second half of 1996. Three major factors contribute to our optimism:
- -   Near-term concerns about the implementation of a major tax reform have
    faded. In early 1996, the municipal market was wary of the growing political
    momentum for tax reform, which could have eroded the value of the market's
    tax-exempt status. However, the momentum slowed substantially and now
    appears to be on the back burner until after the 1996 Presidential election.
    This has added stability to the market.
- -   For high-income households, tax-exempt bonds provide an attractive after-tax
    alternative. Municipal bond yields have elevated to a point where taxable
    equivalent yields range between 8.5 and 10 percent for investors in the 31
    percent tax bracket or higher.
- -   Recent volatility in the equity markets coupled with rising interest rates
    are leading individual investors, as well as institutions, to reexamine
    their allocation of assets. In general, this translates into an increased
    emphasis on fixed-income, which should lend support to the municipal market.
    Looking ahead, inflation fears and concerns about economic growth may
continue to influence the municipal bond market and fund performance results.
Nevertheless, we are optimistic that tax-exempt securities will produce
attractive results for investors during the remainder of 1996.

your continued confidence in your investment with Van Kampen American Capital.

                          PORTFOLIO MANAGEMENT REVIEW
               VAN KAMPEN AMERICAN CAPITAL MUNICIPAL INCOME FUND
 
We recently spoke with the management team of the Van Kampen American Capital
Municipal Income Fund about the key events and economic forces that shaped the
markets during the first half of the Fund's fiscal year. The team includes David
C. Johnson, portfolio manager, and Peter W. Hegel, executive vice president for
fixed-income investments. The following excerpts reflect their views on the
Fund's performance during the six-month period ended June 30, 1996.
   
    Q THE MUNICIPAL BOND MARKET EXPERIENCED SOME FLUCTUATIONS DURING THE FIRST
      SIX MONTHS OF 1996. COULD YOU EXPLAIN WHAT HAPPENED IN THE MARKET DURING
      THIS PERIOD, AND WHAT FACTORS PLAYED THE GREATEST ROLE?
   
    A We did see some significant price fluctuations in the municipal bond
      market during the first half of the year. January was the only period that
      enjoyed the same positive investment environment that dominated the bond
market through most of 1995. In contrast, February brought an abrupt end to the
increase in bond prices, and this environment continued throughout the rest of
the reporting period. Instead of anticipating further interest rate reductions,
the market grew wary that interest rates might be increased (tightened) by the
Federal Reserve Board. This concern was triggered by two main factors:
- -   The federal government was shut down twice, which indicated that balanced
    budget legislation was not imminent.
- -   Several economic indicators pointed to accelerating economic growth.
    Consecutive monthly employment reports showed significant increases in
    employment. For example, 239,000 non-farm jobs were added to the economy in
    June.
 
    These factors led to fears that inflation, which had been holding steady
around 3 percent, might increase. Fears heightened when agricultural commodity
and oil prices rose to their highest levels in two years. As a result, the Fed
shifted policy from an accommodative mode (lowering interest rates) in January
to a stable, or neutral, mode. Thereafter, bond prices generally began to
decrease.
   
    Q HOW WAS THE FUND STRUCTURED OVER THE LAST SIX MONTHS?
   
    A The Fund is managed to seek to provide both an attractive tax-exempt yield
      and a relatively stable net asset value. The majority of the Fund's
      holdings are investment-grade bonds (BBB-rated or higher), with 55 percent
rated single-A or higher. As of June 30, 1996 more than 25 percent of the Fund
was invested in non-rated securities and those rated below investment-grade. By
utilizing both kinds of issues, we are able to position the Fund defensively
against bond price fluctuations. This is because values of non-rated and
lower-rated securities are less dependent on interest rates and more dependent
on credit quality considerations. In contrast, the values of higher-rated
securities are more responsive to changes in interest rates, but these
securities incur less credit risk.

    Over the past six months, the Fund's duration stood at approximately 8
years. Duration is a measurement of a portfolio's sensitivity to changes in
interest rates--the shorter the duration, the less sensitive the portfolio is
expected to be to interest rate movements. The Fund's 8-year duration is
consistent with major municipal bond indices and is a level that allows us to
achieve a balance between maintaining an attractive dividend and protecting the
portfolio against diverse market changes.
    We continue to see value in 15- to 20-year maturities. Acquisitions in the
Fund have emphasized this maturity range, which we believe offers the best
relative value compared to Treasury yields at this time, with less price
volatility than is usually associated with long-term maturities. Please refer to
page four for Fund portfolio highlights.
 
   
    Q WERE THERE SOME OTHER FACTORS THAT INFLUENCED THE MUNICIPAL BOND MARKET
      OVER THE LAST SIX MONTHS?
   
    A The supply and demand relationship continued to be a positive influence on
      the municipal bond market over the reporting period--supply remained low
      while demand remained fairly strong. This helped support bond prices and
partly offset the negative effect that rising interest rates had on bond prices.
    Another influence was the role that potential major tax reform played on
municipal bonds. The market's initial reaction to this issue was negative,
because major reform may remove the tax advantage municipal bonds now offer. We
believe the market has now discounted the potential impact of tax reform, and we
do not expect any type of reform to be implemented until 1997, at the earliest.
However, this issue may continue to receive media coverage throughout the
remainder of 1996, primarily near the presidential election in November, and we
will continue to monitor it closely for any developments.
 
   
    Q WHAT WERE THE MOST ATTRACTIVE SECTORS FOR THE FUND?
   
    A We continued to find value in a wide array of sectors and individual
      issues across many categories for both investment and non-investment grade
      acquisitions. One sector that continues to remain attractive is healthcare
and its related areas. Because we have dedicated analysts who specialize in
thoroughly researching each sector, we continue to find issues offering the
greatest relative value. Recently, the housing sector has also provided some
attractive holdings for the Fund.
   
    Q HOW DID THE FUND PERFORM DURING THE SIX MONTHS ENDED JUNE 30, 1996?
   
    A For the six months ended June 30, 1996, the Fund's total return was -0.76
      percent(1) (Class A shares at net asset value). By comparison, the Lehman
Brothers Municipal Bond Index earned a total return of -0.45 percent over the
same period. Longer term, the Fund generated a one-year total return of 6.26
percent(1) (Class A shares at net asset value) through June 30, 1996. The Lehman
Index is a broad-based, unmanaged index of municipal bonds and does not reflect
any commissions or fees that would be paid by an investor purchasing the
securities it represents. Please refer to the chart on page three for additional
Fund performance results.

    At its current annualized dividend level of $0.882 per share, the Fund
provides shareholders with a tax-free distribution rate of 5.60 percent(3)
(Class A shares) as of June 30, 1996. At this distribution rate, the Fund
provides shareholders in the 36 percent federal income tax bracket with a yield
equivalent to a taxable investment earning 8.75 percent(4).
 
   Q
      WHAT IS YOUR OUTLOOK FOR THE MUNICIPAL BOND MARKET IN THE UPCOMING MONTHS,
      AND WHAT FACTORS COULD INFLUENCE YOUR MANAGEMENT OF THE FUND?
   A
      The municipal market should remain stable over the next few months,
      especially if the current market fundamentals--including low inflation and
      a positive supply and demand ratio--remain in place. We do not anticipate
any significant changes in the management of the Fund. However, if the economy
continues to show signs of strong growth, we could see some changes in market
fundamentals:
 
- -   INFLATION has been holding at a low 2 to 3 percent range for some time now,
    but going forward, there is some concern that inflation could slowly creep
    upward, which could have a negative effect on the market.
- -   INTEREST RATES: We anticipate the Federal Reserve will remain in a neutral
    policy mode, but it may become necessary to tighten interest rates if the
    economy continues to strengthen. However, the Fund is structured defensively
    against such increases with its high-yielding, non-rated holdings.
- -   The positive ratio between LOWER SUPPLY AND HIGHER DEMAND should continue in
    the upcoming months, which is a stabilizing influence on municipal bond
    values. If there is a rally in bond prices, we could see an increase in
    refundings, which could bring more supply into the market.

1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital Municipal Income Fund (the "Fund") is organized as a
series of the Van Kampen American Capital Tax Free Trust, a Delaware business
trust, and is registered as a diversified open-end management investment company
under the Investment Company Act of 1940, as amended. The Fund's investment
objective is to provide a high level of current income exempt from federal
income tax, consistent with preservation of capital. The Fund commenced
investment operations on August 1, 1990. The distribution of the Fund's Class B
and Class C shares commenced on August 24, 1992 and August 13, 1993,
respectively. On July 6, 1995, all Class D shareholders redeemed their shares
and the class was eliminated. The Fund will no longer offer Class D shares.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.

                           June 30, 1996 (Unaudited)
- --------------------------------------------------------------------------------
 
D. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1995, the Fund had an accumulated capital loss
carryforward for tax purposes of $43,018,622. Of this amount, $2,340,989,
$30,738, $15,509, $12,455,739, $7,698,483 and $20,477,164 will expire on
December 31, 1996, 1998, 2000, 2001, 2002 and 2003, respectively. Net realized
gains or losses may differ for financial and tax reporting purposes primarily as
a result of the deferral of post October 31 losses and the capitalization of
reorganization and restructuring costs for tax purposes.
 
E. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes.
 
    Due to inherent differences in the recognition of interest income under
generally accepted accounting principles and federal income tax purposes, for
those securities which the Fund has placed on non-accrual status, the amount of
distributable net investment income may differ between book and federal income
tax purposes for a particular period. These differences are temporary in nature,
but may result in book basis distribution in excess of net investment income for
certain periods.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
 
Under the terms of the Fund's Investment Advisory Agreement, Van Kampen American
Capital Investment Advisory Corp. (the "Adviser") will provide investment advice
and facilities to the Fund for an annual fee payable monthly as follows:

- --------------------------------------------------------------------------------
 
    For the six months ended June 30, 1996, the Fund recognized expenses of
approximately $40,900 representing Van Kampen American Capital Distributors,
Inc.'s or its affiliates' (collectively "VKAC") cost of providing accounting,
cash management and legal services to the Fund.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the six months ended
June 30, 1996, the Fund recognized expenses of approximately $476,200,
representing ACCESS' cost of providing transfer agency and shareholder services
plus a profit.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.
 
    At June 30, 1996, VKAC owned 146 and 137 shares of Classes B and C,
respectively.
 
3. CAPITAL TRANSACTIONS
 
The Fund has outstanding three classes of common shares, Classes A, B and C each
with a par value of $.01 per share. There are an unlimited number of shares of
each class authorized.

    Class B and C shares are offered without a front end sales charge, but are
subject to a contingent deferred sales charge (CDSC). The CDSC will be imposed
on most redemptions made within six years of the purchase for Class B and one
year of the purchase for Class C as detailed in the following schedule. The
Class B and C shares bear the expense of their respective deferred sales
arrangements, including higher distribution and service fees and incremental
transfer agency costs.

- --------------------------------------------------------------------------------
 
    For the six months ended June 30, 1996, VKAC, as Distributor for the Fund,
received commissions on sales of the Fund's Class A shares of approximately
$69,900 and CDSC on redeemed shares of approximately $274,700. Sales charges do
not represent expenses of the Fund.
 
    On September 22, 1995, the Fund acquired all of the assets and liabilities
of the Van Kampen American Capital Municipal Bond Fund (the "AC Fund"), through
a tax free reorganization approved by AC Fund shareholders on September 21,
1995. The Fund issued 20,054,672, 2,774,312 and 471,489 shares of Classes A, B
and C valued at $301,019,346, $41,842,606 and $7,076,761, respectively, in
exchange for AC Fund's net assets. Shares issued in connection with this
reorganization are included in common share sales for the year ended December
31, 1995. Combined net assets on the date of acquisition were $1,027,309,801.
 
4. INVESTMENT TRANSACTIONS
 
During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments and reorganization and restructuring costs,
were $287,388,743 and $309,943,969, respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS
 
A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.
 
    The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in the unrealized
appreciation/depreciation on investments. Upon disposition, a realized gain or
loss is recognized accordingly, except for exercised option contracts where the
recognition of gain or loss is postponed until the disposal of the security
underlying the option contract.
 
    Summarized below are the specific types of derivative financial instruments
used by the Fund.
 
A. OPTION CONTRACTS--An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put)an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration.

</TABLE>
 
B. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Bonds and the Municipal Bond
Index and typically closes the contract prior to the delivery date. These
contracts are generally used to manage the portfolio's effective maturity and
duration.
 
    Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin). The cost of securities acquired through
delivery under a contract is adjusted by the unrealized gain or loss on the
contract.
 
    Transactions in futures contracts for the six months ended June 30, 1996,
were as follows:

</TABLE>
 
C. INDEXED SECURITIES--These instruments are identified in the portfolio of
investments. The price of these securities may be more volatile than the price
of a comparable fixed rate security.
 
    An Inverse Floating security is one where the coupon is inversely indexed to
a short-term floating interest rate multiplied by a specified factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. These instruments are typically used by the
Fund to enhance the yield of the portfolio.
 
    An Embedded Swap security includes a swap component such that the fixed
coupon component of the underlying bond is adjusted by the difference between
the securities fixed swap rate and the floating swap index. These instruments
are typically used by the Fund to enhance the yield of the portfolio.
 
6. DISTRIBUTION AND SERVICE PLANS
 
The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940 and a service plan (collectively
the "Plans"). The Plans govern payments for the distribution of the Fund's
shares, ongoing shareholder services and maintenance of shareholder accounts.
 
    Annual fees under the Plans of up to .25% for Class A and 1.00% each for
Class B and Class C shares are accrued daily. Included in these fees for the six
months ended June 30, 1996, are payments to VKAC of approximately $802,500.

August 1, 1996
 
Dear Shareholder,
    As you may be aware, an agreement
was reached in late June for VK/AC
Holding, Inc., the parent company of
Van Kampen American Capital, Inc., to
be acquired by the Morgan Stanley
Group Inc. While this announcement
may appear commonplace in an
ever-changing financial industry, we                     [PHOTO]         
believe it represents an exciting
opportunity for shareholders of our
investment products.                       DENNIS J. MCDONNELL AND DON G. POWELL
    With Morgan Stanley's global
leadership in investment banking and
asset management and Van Kampen American Capital's reputation for competitive
long-term performance and superior investor services, together we will offer a
broader range of investment opportunities and expertise.
    The new ownership will not affect our commitment to pursuing excellence in
all aspects of our business. And, we expect very little change in the way your
mutual fund account is maintained and serviced.
    A proxy will be mailed to you shortly explaining the acquisition and asking
for your vote of approval. Please read it carefully and return your response for
inclusion in the shareholder vote. We value our relationship with you and look
forward to communicating more details of this transaction, which is anticipated
to be completed in November.
 
ECONOMIC REVIEW AND OUTLOOK
    The economy demonstrated an acceleration in growth during the six-month
reporting period. After a nominal 0.3 percent growth rate in the last quarter of
1995, GDP (the nation's gross domestic product) rose by 2.0 percent in this
year's first quarter. And, as anticipated, the economy grew by 4.2 percent in
the second quarter, partly reflecting a recovery from the effects of labor
strikes earlier in the year and extreme weather conditions across the country.
Upward momentum has been assisted by consumer spending, as indicated by a 5.6
percent rise in retail sales in the first five months of this year versus the
comparable 1995 period.
    In the manufacturing sector, economic reports, such as the National
Association of Purchasing Managers Index, suggested a continued rebound in
production from last winter's lower levels. In June, this index reached its
highest level since early 1995. Strong levels of exports and a replenishing of
inventories have helped support this momentum.
    Surprisingly healthy economic activity led to concerns that inflation may
rise and the Federal Reserve Board might tighten monetary policy. Inflation
remains modest, however, with consumer prices rising at about a 3 percent annual
rate over the past year. Meanwhile, the closely watched "core" Consumer Price
Index, which excludes volatile food and energy components, has risen year over
year at rates between 2.7 and 3.0 percent per year, with mid-1996 readings at a
moderate 2.7 percent. In general, recent reports have suggested an upward creep
in labor-related costs, while indicating that prices of many commodities have
begun to decline.

    We anticipate that reasonably strong economic growth will continue during
the balance of 1996, albeit at more moderate rates than the second quarter's
swift pace. While we expect rates of inflation to remain near current levels,
the Fed may begin to lean toward greater restraint in its monetary policy in the
coming months. That suggests an upward bias for short-term interest rates and
for yields on long-term bonds to remain steady at current levels. Specifically,
we expect 10-year Treasury yields to trade within a range of 5.7 and 6.3
percent, particularly when compared to taxable investments.
 
MUNICIPAL MARKET REVIEW AND OUTLOOK
    We witnessed significant movement in municipal bond yields during the first
six months of 1996. Early in the period, the Fed lowered rates in order to
energize the economy, and bond prices increased. By late February, however, the
markets became concerned that the Fed could reverse its strategy direction and
raise rates. As a result, yields, as measured by the Bond Buyer 40 Municipal
Bond Index, rose from 5.6 percent to 6.0 percent during the period.
    We believe market conditions for municipal bonds are poised for improvement
in the second half of 1996. Three major factors contribute to our optimism:
- -   Near-term concerns about the implementation of a major tax reform have
    faded. In early 1996, the municipal market was wary of the growing political
    momentum for tax reform, which could have eroded the value of the market's
    tax-exempt status. However, the momentum slowed substantially and now
    appears to be on the back burner until after the 1996 presidential election.
    This has added stability to the market.
- -   For high-income households, tax-exempt bonds provide an attractive after-tax
    alternative. Municipal bond yields have elevated to a point where taxable
    equivalent yields range between 8.5 and 10 percent for investors in the 31
    percent tax bracket or higher.
- -   Recent volatility in the equity markets coupled with rising interest rates
    are leading individual investors, as well as institutions, to reexamine
    their allocation of assets. In general, this translates into an increased
    emphasis on fixed-income, which should lend support to the municipal market.
    Looking ahead, inflation fears and concerns about economic growth may
continue to influence the municipal bond market and fund performance results.
Nevertheless, we are optimistic that tax-exempt securities will produce
attractive results for investors during the remainder of 1996.

                          PORTFOLIO MANAGEMENT REVIEW
      VAN KAMPEN AMERICAN CAPITAL INTERMEDIATE TERM MUNICIPAL INCOME FUND
 
We recently spoke with the management team of the Van Kampen American Capital
Intermediate Term Municipal Income Fund about the key events and economic forces
that shaped the markets during the first half of the Fund's fiscal year. The
team is led by David C. Johnson, portfolio manager, and Peter W. Hegel,
executive vice president for fixed-income investments. The following excerpts
reflect their views on the Fund's performance during the six-month period ended
June 30, 1996.
    
   Q  THE MUNICIPAL BOND MARKET EXPERIENCED SOME FLUCTUATIONS DURING THE FIRST
      SIX MONTHS OF 1996. COULD YOU EXPLAIN WHAT HAPPENED IN THE MARKET DURING
      THIS PERIOD AND WHAT FACTORS PLAYED THE GREATEST ROLE?
    
   A  We did see some significant price fluctuations in the municipal bond
      market during the first half of the year. January was the only period that
      enjoyed the same positive investment environment that dominated the bond
market through most of 1995. In contrast, February brought an abrupt end to the
increase in bond prices, and this environment continued throughout the rest of
the reporting period. Instead of anticipating further interest rate reductions,
the market grew wary that interest rates might be increased (tightened) by the
Fed. This concern was triggered by two main factors:
- -   The federal government was shut down twice, which indicated that balanced
    budget legislation was not imminent.
- -   Several economic indicators pointed to accelerating economic growth.
    Consecutive monthly employment reports showed significant increases in
    employment.
    These factors led to fears that inflation, which had been holding steady
around 3 percent, might increase. Fears heightened when agricultural commodity
and oil prices rose to their highest levels in two years. As a result, the Fed
shifted policy from an accommodative mode (lowering interest rates) in January
to a stable, or neutral, mode. Thereafter, bond prices generally began to
decrease.
    
   Q  WERE THERE OTHER FACTORS THAT INFLUENCED THE MUNICIPAL BOND MARKET OVER
      THE LAST SIX MONTHS?
    
   A  The supply and demand relationship continued to be a positive influence on
      the municipal bond market over the reporting period--supply remained low
      while demand remained fairly strong. This helped support bond prices and
partly offset the negative effect that rising interest rates had on bond prices.
    Another influence was the role that potential major tax reform played on
municipal bonds. The market's initial reaction to this issue was negative,
because major tax reform may remove the tax advantage municipal bonds now offer.
We believe the market has now discounted the potential impact of tax reform, and
we do not expect any type of reform to be implemented until 1997, at the
earliest. However, this issue may continue to receive media coverage throughout
the remainder of 1996, primarily near the presidential election in November, and
we will continue to monitor it closely for any developments.
 
                                        5
<PAGE>   152
 
    
   Q  HOW WAS THE FUND STRUCTURED OVER THE LAST SIX MONTHS?
    
   A  The Fund currently holds 4.4 percent in securities rated below
      investment-grade. Securities rated below investment-grade quality
      typically offer higher yields than investment-grade quality to compensate
for the additional credit risk. Our challenge has been to find issues offering
the greatest relative value in this low-supply environment.
    The Fund was structured defensively with a relatively short duration of 6.5
years, which remained consistent during the six-month period. Duration is a
measurement of a portfolio's sensitivity to interest rate changes--the shorter
the duration, the less sensitive the portfolio is expected to be to interest
rate movements. The Fund's short duration is consistent with major municipal
bond indices and allows us to achieve a balance between maintaining an
attractive dividend and seeking to protect the portfolio against market
fluctuations.
    We continue to believe the intermediate sector of the municipal market
(10-year securities) remains particularly attractive in relation to Treasury
yields. The intermediate sector has traditionally offered competitive yields
when compared to longer-term issues, though with less price volatility than is
usually associated with these types of securities. Please refer to page four for
Fund portfolio highlights.
    
   Q  WHAT WERE THE MOST ATTRACTIVE SECTORS FOR THE FUND?
    
   A  We continued to find value in a wide array of sectors and individual
      issues across many categories for both investment and non-investment grade
      acquisitions. One sector that remains attractive is healthcare and its
related areas (currently at 19.9 percent of the Fund's holdings). Because we
have dedicated analysts who specialize in thoroughly researching each sector, we
continue to find issues offering the greatest relative value.
    
   Q  HOW DID THE FUND PERFORM DURING THE SIX MONTHS ENDED JUNE 30, 1996?
    
   A  During the period's volatile market environment, the Fund returned -0.03
      percent(1) (Class A shares at net asset value) for the six months ended
      June 30, 1996. By comparison, the Lehman Brothers Municipal Bond Index was
less favorable, with a total return of -0.45 percent over the same period.
Longer term, the Fund generated a one-year total return of 5.64 percent(1)
(Class A shares at net asset value). The Lehman Index is a broad-based,
unmanaged index of municipal bonds and does not reflect any commissions or fees
that would be paid by an investor purchasing the securities it represents.
Please refer to the chart on page three for additional Fund performance results.
    At its current annualized dividend level of $0.474 per share, the Fund
generated a tax-free distribution rate of 4.58 percent(3) (Class A shares) as of
June 30, 1996. At this distribution rate, the Fund provides shareholders in the
36 percent federal income tax bracket with a yield equivalent to a taxable
investment earning 7.16 percent(4).

<PAGE>   153
 
    
   Q  WHAT IS YOUR OUTLOOK FOR THE MUNICIPAL BOND MARKET IN THE UPCOMING MONTHS,
      AND WHAT FACTORS COULD INFLUENCE YOUR MANAGEMENT OF THE FUND?
    
   A  The municipal market should remain stable over the next few months,
      especially if the current market fundamentals--including low inflation and
      a positive supply and demand ratio--remain in place. We do not anticipate
any significant changes in the management of the Fund. However, if the economy
continues to show signs of strong growth, we could see some changes in market
fundamentals:
- -   INFLATION has been holding at a low 2 to 3 percent range for some time now,
    but going forward, there is some concern that inflation could slowly creep
    upward, which could have a negative effect on the market.
- -   INTEREST RATES: We anticipate the Federal Reserve will remain in a neutral
    policy mode, but it may become necessary to tighten interest rates if the
    economy continues to strengthen.
- -   The positive ratio between LOWER SUPPLY AND HIGHER DEMAND should continue in
    the upcoming months, which is a stabilizing influence on municipal bond
    values. If there is a rally in bond prices, we could see an increase in
    refundings, which could bring more supply into the market.

*Zero coupon bond
</TABLE>
 
(a) At June 30, 1996, cost for federal income tax purposes is $32,148,380; the
    aggregate gross unrealized appreciation is $1,342,188 and the aggregate
    gross unrealized depreciation is $108,846, resulting in net unrealized
    appreciation of $1,233,342.
 
(b) Securities purchased on a when issued or delayed delivery basis.
 
(c) Assets segregated as collateral for when issued or delayed delivery purchase
    commitments.
 
(d) An Embedded Swap security includes a swap component such that the fixed
    coupon component of the underlying bond is adjusted by the difference
    between the security's fixed swap rate and the floating swap index. As the
    floating rate rises, the coupon is reduced. Conversely, as the floating rate
    declines, the coupon is increased. The price of these securities may be more
    volatile than the price of a comparable fixed rate security. These are
    typically used by the Fund to enhance the yield of the portfolio.

1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital Intermediate Term Municipal Income Fund (the "Fund")
is organized as a series of Van Kampen American Capital Tax Free Trust (the
"Trust"), a Delaware business trust, and is registered as a diversified open-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to seek a high level of current
income exempt from federal income tax, consistent with preservation of capital.
The Fund commenced investment operations on May 28, 1993 with two classes of
common shares, Class A and Class B shares. The distribution of the Fund's Class
C shares commenced on October 19, 1993.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amount of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.

                           June 30, 1996 (Unaudited)
- --------------------------------------------------------------------------------
 
D. ORGANIZATIONAL EXPENSES--The Fund has reimbursed Van Kampen American Capital
Distributors, Inc. or its affiliates (collectively "VKAC") for costs incurred in
connection with the Fund's organization in the amount of $60,000. These costs
are being amortized on a straight line basis over the 60 month period ending May
27, 1998. Van Kampen American Capital Investment Advisory Corp. (the "Adviser")
has agreed that in the event any of the initial shares of the Fund originally
purchased by VKAC are redeemed during the amortization period, the Fund will be
reimbursed for any unamortized organizational expenses in the same proportion as
the number of shares redeemed bears to the number of initial shares held at the
time of redemption.
 
E. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of loss and offset such losses against any future realized capital gains.
At December 31, 1995, the Fund had an accumulated capital loss carryforward of
$1,033,130, of which $849,643 and $183,487 will expire on December 31, 2002 and
2003, respectively. Net realized gains or losses may differ for financial and
tax reporting purposes primarily as a result of post October 31 losses which are
not recognized for tax purposes until the first day of the following fiscal
year.
 
F. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
 
Under the terms of the Fund's Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Fund for an annual fee payable
monthly as follows:

- --------------------------------------------------------------------------------
 
    For the six months ended June 30, 1996, the Fund recognized expenses of
approximately $8,700 representing VKAC's cost of providing accounting, cash
management and legal services to the Fund.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
June 30, 1996, the Fund recognized expenses of approximately $17,900,
representing ACCESS' cost of providing transfer agency and shareholder services
plus a profit.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.
 
    At June 30, 1996, VKAC owned 1,000, 100 and 100 shares of beneficial
interest of Classes A, B and C, respectively.
 
3. CAPITAL TRANSACTIONS
 
The Fund has outstanding three classes of common shares, Classes A, B and C each
with a par value of $.01 per share. There are an unlimited number of shares of
each class authorized.

August 1, 1996
 
Dear Shareholder,
    As you may be aware, an agreement
was reached in late June for VK/AC                      [PHOTO]
Holding, Inc., the parent company of
Van Kampen American Capital, Inc., to     DENNIS J. MCDONNELL AND DON G. POWELL
be acquired by the Morgan Stanley
Group Inc. While this announcement        
may appear commonplace in an
ever-changing financial industry, we
believe it represents an exciting
opportunity for shareholders of our
investment products.
    With Morgan Stanley's global
leadership in investment banking and
asset management and Van Kampen American Capital's reputation for competitive
long-term performance and superior investor services, together we will offer a
broader range of investment opportunities and expertise.
    The new ownership will not affect our commitment to pursuing excellence in
all aspects of our business. And, we expect very little change in the way your
mutual fund account is maintained and serviced.
    A proxy will be mailed to you shortly explaining the acquisition and asking
for your vote of approval. Please read it carefully and return your response for
inclusion in the shareholder vote. We value our relationship with you and look
forward to communicating more details of this transaction, which is anticipated
to be completed in November.
 
ECONOMIC REVIEW AND OUTLOOK
    The economy demonstrated an acceleration in growth during the six-month
reporting period. After a nominal 0.3 percent growth rate in the last quarter of
1995, GDP (the nation's gross domestic product) rose by 2.0 percent in this
year's first quarter. And, as anticipated, the economy grew by 4.2 percent in
the second quarter, partly reflecting a recovery from the effects of labor
strikes earlier in the year and extreme weather conditions across the country.
Upward momentum has been assisted by consumer spending, as indicated by a 5.6
percent rise in retail sales in the first five months of this year versus the
comparable 1995 period.
    In the manufacturing sector, economic reports, such as the National
Association of Purchasing Managers Index, suggested a continued rebound in
production from last winter's lower levels. In June, this index reached its
highest level since early 1995. Strong levels of exports and a replenishing of
inventories have helped support this momentum.
    Surprisingly healthy economic activity led to concerns that inflation may
rise and the Federal Reserve Board might tighten monetary policy. Inflation
remains modest, however, with consumer prices rising at about a 3 percent annual
rate over the past year. Meanwhile, the closely watched "core" Consumer Price
Index, which excludes volatile food and energy components, has risen year over
year at rates between 2.7 and 3.0 percent per year, with mid-1996 readings at a
moderate 2.7 percent. In general, recent reports have suggested an upward creep
in labor-related costs, while indicating that prices of many commodities have
begun to decline.
 
                                                           Continued on page two
 
                                        1
<PAGE>   173
 
    We anticipate that reasonably strong economic growth will continue during
the balance of 1996, albeit at more moderate rates than the second quarter's
swift pace. While we expect rates of inflation to remain near current levels,
the Fed may begin to lean toward greater restraint in its monetary policy in the
coming months. That suggests an upward bias for short-term interest rates and
for yields on long-term bonds to remain steady at current levels. Specifically,
we expect 10-year Treasury yields to trade within a range of 5.7 and 6.3
percent, particularly when compared to taxable investments.
 
MUNICIPAL MARKET REVIEW AND OUTLOOK
    We witnessed significant movement in municipal bond yields during the first
six months of 1996. Early in the period, the Fed lowered rates in order to
energize the economy, and bond prices increased. By late February, however, the
markets became concerned that the Fed could reverse its strategy direction and
raise rates. As a result, yields, as measured by the Bond Buyer 40 Municipal
Bond Index, rose from 5.6 percent to 6.0 percent during the period.
    We believe market conditions for municipal bonds are poised for improvement
in the second half of 1996. Three major factors contribute to our optimism:
- -   Near-term concerns about the implementation of a major tax reform have
    faded. In early 1996, the municipal market was wary of the growing political
    momentum for tax reform, which could have eroded the value of the market's
    tax-exempt status. However, the momentum slowed substantially and now
    appears to be on the back burner until after the 1996 presidential election.
    This has added stability to the market.
- -   For high-income households, tax-exempt bonds provide an attractive after-tax
    alternative. Municipal bond yields have elevated to a point where taxable
    equivalent yields range between 8.5 and 10 percent for investors in the 31
    percent tax bracket or higher.
- -   Recent volatility in the equity markets coupled with rising interest rates
    are leading individual investors, as well as institutions, to reexamine
    their allocation of assets. In general, this translates into an increased
    emphasis on fixed-income, which should lend support to the municipal market.
    Looking ahead, inflation fears and concerns about economic growth may
continue to influence the municipal bond market and fund performance results.
Nevertheless, we are optimistic that tax-exempt securities will produce
attractive results for investors during the remainder of 1996.

your continued confidence in your investment with Van Kampen American Capital.

(5)SEC Yield is a standardized calculation prescribed by the Securities and
Exchange Commission for determining the amount of net income a portfolio should
theoretically generate for the 30-day period ending June 30, 1996. Had certain
expenses of the Fund not been assumed by VKAC, the SEC Yield would have been
3.91%, 3.41% and 3.41% for Classes A, B and C, respectively, and total returns
would have been lower.
 
A portion of the interest income may be taxable for those investors subject to
the federal alternative minimum tax (AMT).

                          PORTFOLIO MANAGEMENT REVIEW
        VAN KAMPEN AMERICAN CAPITAL FLORIDA INSURED TAX FREE INCOME FUND
 
We recently spoke with the management team of the Van Kampen American Capital
Florida Insured Tax Free Income Fund about the key events and economic forces
that shaped the markets during the first half of the Fund's fiscal year. The
team includes Joseph A. Piraro, portfolio manager, and Peter W. Hegel, executive
vice president for fixed-income investments. The following excerpts reflect
their views on the Fund's performance during the six-month period ended June 30,
1996.

   Q  WHAT EVENTS OR MARKET CONDITIONS HAD THE GREATEST IMPACT ON THE FUND
      DURING THE FIRST HALF OF THIS YEAR?

   A  Earlier in the year, indicators pointing to a stronger, expanding economy
      sparked concern over inflation and expectations that the Federal Reserve
      Board would increase short-term interest rates in order to keep the
economy from overheating. The prospect of higher rates was a concern to the
market, which responded by trading toward lower prices and higher yields.
    On the other hand, municipal market concerns that major tax reform proposals
may gain acceptance--and potentially erode the tax-exempt status associated with
municipals--eased in the first half of 1996. So, even though bond prices
generally declined, they did so to a lesser extent in the municipal market.
    The supply and demand relationship continued to be a positive influence on
the municipal bond market over the reporting period--supply remained low while
demand remained fairly strong. This helped support bond prices and partly offset
the negative effect that rising interest rates had on bond prices.
 
   Q  HOW WAS THE FUND'S PORTFOLIO STRUCTURED IN LIGHT OF
      THESE CONDITIONS?

   A  The Fund was structured with a duration of 9.4 years at the end of the
      period, which is slightly higher than the benchmark that we try to target
      over time. Duration is a measure of a portfolio's sensitivity to changes
in interest rates. The shorter the duration, the less sensitive the portfolio is
expected to be to interest rates. The Fund's average weighted maturity remained
in the 20- to 22-year range, which we feel offered the best balance between
income and total return performance.
    The majority of the Fund's holdings are invested in AAA-rated securities
(87.5 percent), and the Florida municipal market continues to offer value in a
variety of sectors. Currently, the Fund has its highest concentration in public
education at 25.1 percent and healthcare at 19.3 percent. Please refer to page
four for Fund portfolio highlights.

<PAGE>   177
 
   Q  HOW DID THE FUND PERFORM DURING THE SIX MONTHS ENDED JUNE 30, 1996?

   A  For the six-month period ended June 30, 1996, the Fund's total return was
      -1.54 percent(1) (Class A shares at net asset value). By comparison, the
      market in general, as represented by the Lehman Brothers Municipal Bond
Index, returned -0.45 percent for the same period. Longer term, the Fund
generated a one-year total return of 5.95 percent(1) (Class A shares at net
asset value) through June 30, 1996. The Lehman Index is a broad-based, unmanaged
index of municipal bonds and does not reflect any commissions or fees that would
be paid by an investor purchasing the securities it represents. Please refer to
the chart on page three for additional Fund performance results.
    At its current annualized dividend of $0.774 per share, the Fund generated a
tax-free distribution rate of 5.06 percent(3) (Class A shares) as of June 30,
1996. At this distribution rate, the Fund provides shareholders in the 36
percent federal income tax bracket with a yield equivalent to a taxable
investment earning 7.91 percent(4).
 
   Q  WHAT IS YOUR OUTLOOK FOR THE MARKET IN THE MONTHS AHEAD?

   A  The Florida economy is generally sound, and we do not anticipate any
      significant changes in the management of the Fund. However, if the
      national economy continues to show signs of strong growth, we could see
some changes in market fundamentals:
- -   INFLATION has been holding at a low 2 to 3 percent range for some time now,
    but going forward, there is some concern that inflation could slowly creep
    upward, which could have a negative effect on the market.
- -   INTEREST RATES: We anticipate the Federal Reserve will remain in a neutral
    policy mode, but it may become necessary to tighten interest rates if the
    economy continues to strengthen.
- -   The positive ratio between LOWER SUPPLY AND HIGHER DEMAND should continue in
    the upcoming months, which is a stabilizing influence on municipal bond
    values. If there is a rally in bond prices, we could see an increase in
    refundings, which could bring more supply into the market.

1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital Florida Insured Tax Free Income Fund (the "Fund") is
organized as a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust, and is registered as a non-diversified open-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to provide investors a high level of
current income exempt from federal income and Florida state intangibles taxes,
consistent with preservation of capital. Under normal market conditions, the
Fund will invest at least 80% of its assets in insured Florida municipal
securities. The Fund commenced investment operations on July 29, 1994.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount on securities purchased are amortized over
the expected life of each applicable security.

                           June 30, 1996 (Unaudited)
- --------------------------------------------------------------------------------
 
D. ORGANIZATIONAL EXPENSES--The Fund will reimburse Van Kampen American Capital
Distributors, Inc. or its affiliates (collectively "VKAC") for costs incurred in
connection with the Fund's organization in the amount of $120,000. These costs
are being amortized on a straight line basis over the 60 month period ending
July 28, 1999. Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") has agreed that in the event any of the initial shares of the Fund
originally purchased by VKAC are redeemed during the amortization period, the
Fund will be reimbursed for any unamortized organizational expenses in the same
proportion as the number of shares redeemed bears to the number of initial
shares held at the time of redemption.
 
E. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income, if any, to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1995, the Fund had an accumulated capital loss
carryforward for tax purposes of $259,956, of which $41,580 and $218,376 will
expire on December 31, 2002 and 2003, respectively. Net realized gains or losses
may differ for financial and tax reporting purposes primarily as a result of
post October 31 losses which are not recognized for tax purposes until the first
day of the following fiscal year.
 
F. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Due to inherent differences in the recognition of certain
expenses under generally accepted accounting principles and federal income tax
purposes, the amount of distributable net investment income may differ between
book and federal income tax purposes for a particular period. These differences
are temporary in nature, but may result in book basis distribution in excess of
net investment income for certain periods.
 
G. EXPENSE REDUCTIONS--During the six months ended June 30, 1996, the Fund's
custody fee was reduced by approximately $1,300 as a result of credits earned on
overnight cash balances.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
 
Under the terms of the Fund's Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Fund for an annual fee payable
monthly as follows:

</TABLE>
 
    Certain legal expenses are paid to Skadden, Arps, Slate, Meagher & Flom,
counsel to the Fund, of which a trustee of the Fund is an affiliated person.
 
    For the six months ended June 30, 1996, the Fund incurred expenses of
approximately $7,800 representing VKAC's cost of providing accounting, cash
management and legal services to the Fund. All of these expenses were assumed by
VKAC.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the six months ended
June 30, 1996, the Fund incurred expenses of approximately $4,100, representing
ACCESS' cost of providing transfer agency and shareholder services plus a
profit, all of which was assumed by VKAC.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.
 
    At June 30, 1996, VKAC owned 100 shares each of Classes A, B and C.
 
3. CAPITAL TRANSACTIONS
 
The Fund has outstanding three classes of common shares, Classes A, B and C each
with a par value of $.01 per share. There are an unlimited number of shares of
each class authorized.

4. INVESTMENT TRANSACTIONS

excluding short-term investments, for the six months ended June 30, 1996, were
$12,068,835 and $9,981,486, respectively.
 
5. DERIVATIVE FINANCIAL INSTRUMENTS
 
A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.
 
    The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolios effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in the unrealized
appreciation/depreciation on investments. Upon disposition, a realized gain or
loss is recognized accordingly, except for exercised option contracts where the
recognition of gain or loss is postponed until the disposal of the security
underlying the option contract.
 
    Summarized below are the specific types of derivative financial instruments
used by the Fund.

- --------------------------------------------------------------------------------
 
A. OPTION CONTRACTS--An option contract gives the buyer the right, but not the
obligation to buy (call) or sell (put) an underlying item at a fixed exercise
price during a specified period. These contracts are generally used by the Fund
to manage the portfolio's effective maturity and duration.
 
    Transactions in options for the six months ended June 30, 1996, were as
follows:

B. FUTURES CONTRACTS--A futures contract is an agreement involving the delivery
of a particular asset on a specified future date at an agreed upon price. The
Fund generally invests in futures on U.S. Treasury Bonds and the Municipal Bond
Index and typically closed the contract prior to the delivery date.
 
    Upon entering into futures contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin). The cost of securities acquired through
delivery under a contract is adjusted by the unrealized gain or loss on the
contract.
 
    Transactions in futures contracts, each with a par value of $100,000, for
the six months ended June 30, 1996, were as follows:

6. DISTRIBUTION AND SERVICE PLANS
 
The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940 and a service plan (collectively
the "Plans"). The Plans govern payments for the distribution of the Fund's
shares, ongoing shareholder services and maintenance of shareholder accounts.
 
    Annual fees under the Plans of up to .25% of Class A shares and 1.00% each
of Class B and Class C shares are accrued daily. Included in these fees for the
six months ended June 30, 1996, are payments to VKAC of approximately $62,700.

August 1, 1996
 
Dear Shareholder,
    As you may be aware, an agreement
was reached in late June for VK/AC
Holding, Inc., the parent company of
Van Kampen American Capital, Inc., to
be acquired by the Morgan Stanley                        [PHOTO]
Group Inc. While this announcement
may appear commonplace in an                  
ever-changing financial industry, we
believe it represents an exciting
opportunity for shareholders of our
investment products.
    With Morgan Stanley's global         DENNIS J. MCDONNELL AND DON G. POWELL
leadership in investment banking and   
asset management and Van Kampen American Capital's reputation for competitive
long-term performance and superior investor services, together we will offer a
broader range of investment opportunities and expertise.
    The new ownership will not affect our commitment to pursuing excellence in
all aspects of our business. And, we expect very little change in the way your
mutual fund account is maintained and serviced.
    A proxy will be mailed to you shortly explaining the acquisition and asking
for your vote of approval. Please read it carefully and return your response for
inclusion in the shareholder vote. We value our relationship with you and look
forward to communicating more details of this transaction, which is anticipated
to be completed in November.
 
ECONOMIC REVIEW AND OUTLOOK
    The economy demonstrated an acceleration in growth during the six-month
reporting period. After a nominal 0.3 percent growth rate in the last quarter of
1995, GDP (the nation's gross domestic product) rose by 2.0 percent in this
year's first quarter. And, as anticipated, the economy grew by 4.2 percent in
the second quarter, partly reflecting a recovery from the effects of labor
strikes earlier in the year and extreme weather conditions across the country.
Upward momentum has been assisted by consumer spending, as indicated by a 5.6
percent rise in retail sales in the first five months of this year versus the
comparable 1995 period.
    Surprisingly healthy economic activity led to concerns that inflation may
rise and the Federal Reserve Board might tighten monetary policy. Inflation
remains modest, however, with consumer prices rising at about a 3 percent annual
rate over the past year. Meanwhile, the closely watched "core" Consumer Price
Index, which excludes volatile food and energy components, has risen year over
year at rates between 2.7 and 3.0 percent per year, with mid-1996 readings at a
moderate 2.7 percent. In general, recent reports have suggested an upward creep
in labor-related costs, while indicating that prices of many commodities have
begun to decline.
    We anticipate that reasonably strong economic growth will continue during
the balance of 1996, albeit at more moderate rates than the second quarter's
swift pace. While we expect rates of inflation to remain near current levels,
the Fed may begin to lean toward greater restraint in its monetary policy in the
coming months. That suggests an upward bias for short-term interest rates and
for yields on long-term bonds to remain steady at current levels. Specifically,
we expect 10-year Treasury yields to trade within a range of 5.7 and 6.3
percent, particularly when compared to taxable investments.

MUNICIPAL MARKET REVIEW AND OUTLOOK
 
    We witnessed significant movement in municipal bond yields during the first
six months of 1996. Early in the period, the Fed lowered rates in order to
energize the economy, and bond prices increased. By late February, however, the
markets became concerned that the Fed could reverse its strategy direction and
raise rates. As a result, yields, as measured by the Bond Buyer 40 Municipal
Bond Index, rose from 5.6 percent to 6.0 percent during the period.
    We believe market conditions for municipal bonds are poised for improvement
in the second half of 1996. Three major factors contribute to our optimism:
 
- -  Near-term concerns about the implementation of a major tax reform have faded.
   In early 1996, the municipal market was wary of the growing political
   momentum for tax reform, which could have eroded the value of the market's
   tax-exempt status. However, the momentum slowed substantially and now appears
   to be on the back burner until after the 1996 presidential election. This has
   added stability to the market.
 
- -  For high-income households, tax-exempt bonds provide an attractive after-tax
    alternative. Municipal bond yields have elevated to a point where taxable
   equivalent yields range between 8.5 and 10 percent for investors in the 31
   percent tax bracket or higher.
 
- -  Recent volatility in the equity markets coupled with rising interest rates
   are leading individual investors, as well as institutions, to reexamine their
   allocation of assets. In general, this translates into an increased emphasis
   on fixed-income, which should lend support to the municipal market.
    Looking ahead, inflation fears and concerns about economic growth may
continue to influence the municipal bond market and fund performance results.
Nevertheless, we are optimistic that tax-exempt securities will produce
attractive results for investors during the remainder of 1996.
 
FUND UPDATE
 
    The Trustees of your Fund have recently approved its reorganization into the
Van Kampen American Capital Municipal Income Fund. The reorganization is subject
to shareholder approval. If approved, New Jersey Tax Free Income Fund
shareholders will receive shares of the Municipal Income Fund in exchange for
their current shares. Similar to the New Jersey Tax Free Income Fund, the
Municipal Income Fund seeks to provide a high level of current income exempt
from federal income tax, consistent with preservation capital. Moreover, because
the Municipal Income Fund invests in municipal bonds from across the country and
in various levels of credit ratings, it offers investors a higher level of
diversification and income potential than a single-state fund.
    You will receive a proxy statement and voting card in the near future. The
proxy is designed to provide you with information about the proposed
reorganization and to request your participation in the proxy process. We
appreciate your continued confidence in your investment with Van Kampen American
Capital.
Sincerely,

(1)Assumes reinvestment of all distributions for the period and does not include
payment of the maximum sales charge (4.75% for A shares) or contingent deferred
sales charge for early withdrawal (4% for B shares and 1% for C shares).
 
(2)Standardized total return. Assumes reinvestment of all distributions for the
period and includes payment of the maximum sales charge (A shares) or contingent
deferred sales charge for early withdrawal (B and C shares).
 
(3)Distribution rate represents the monthly annualized distributions of the Fund
at the end of the period and not the earnings of the Fund.
 
(4)The taxable-equivalent distribution rate is calculated assuming a 40.1%
combined effective federal and state tax bracket, which takes into consideration
the deductibility of individual state taxes paid.
 
(5)SEC Yield is a standardized calculation prescribed by the Securities and
Exchange Commission for determining the amount of net income a portfolio should
theoretically generate for the 30-day period ending June 30, 1996. Had certain
expenses of the Fund not been assumed by VKAC, total return would have been
lower and the SEC Yield would have been 3.64%, 3.15% and 3.15% for Classes A, B
and C, respectively.
 
A portion of the interest income may be taxable for investors subject to the
federal alternative minimum tax (AMT).
 
See the Fund Performance section of the current prospectus. Past performance
does not guarantee future results. Investment return and net asset value will
fluctuate with market conditions. Fund shares, when redeemed, may be worth more
or less than their original cost.

                          PORTFOLIO MANAGEMENT REVIEW
          VAN KAMPEN AMERICAN CAPITAL NEW JERSEY TAX FREE INCOME FUND
 
We recently spoke with the management team of the Van Kampen American Capital
New Jersey Tax Free Income Fund about the key events and economic forces that
shaped the markets during the first half of the Fund's fiscal year. The team
includes Timothy D. Haney, portfolio manager, and Peter W. Hegel, executive vice
president for fixed-income investments. The following excerpts reflect their
views on the Fund's performance during the six-month period ended June 30, 1996.
   
   Q  WHAT EVENTS OR MARKET CONDITIONS HAD THE GREATEST IMPACT ON THE FUND
      DURING THE FIRST HALF OF THIS YEAR?
   
   A  Early in the year, indicators pointing to a stronger, expanding economy
      sparked concern over inflation and expectations that the Federal Reserve
      Board would increase short-term interest rates to keep the economy from
overheating. The prospect of higher rates was a concern to the market, which
responded by trading toward lower prices and higher yields.
    On the other hand, municipal market concerns that major tax reform proposals
may gain acceptance--and potentially erode the tax-exempt status associated with
municipals--eased in the first half of 1996. So, even though bond prices
generally declined, they did so to a lesser extent in the municipal market.
    The supply and demand relationship continued to be a positive influence on
the municipal bond market over the reporting period--supply remained low while
demand remained fairly strong. This helped support bond prices and partly offset
the negative effect that rising interest rates had on bond prices.
 
   
   Q  HOW WAS THE FUND'S PORTFOLIO STRUCTURED IN LIGHT OF
      THESE CONDITIONS?
   
   A  The Fund was structured with a duration of 8.25 years at the end of the
      period, which is slightly higher than the benchmark that we try to target
      over time. Duration is a measure of a portfolio's sensitivity to changes
in interest rates. The shorter the duration, the less sensitive the portfolio is
expected to be to interest rates. The Fund's average weighted maturity remained
at 20 years, which we feel offered the best overall balance between income and
total return performance.
    One of the biggest challenges that we faced was finding New Jersey state
issues that offered relative value in the current low supply environment. The
highest concentration of holdings continues to be in the healthcare sector,
representing 26.9 percent of the Fund's portfolio. We believe healthcare is
attractive primarily because the majority of new issues have been from this
sector. Please refer to page four for Fund portfolio highlights.
 
                                        5
<PAGE>   202
 
   Q  HOW DID THE FUND PERFORM DURING THE PERIOD?
      
   A  For the six-month period ended June 30, 1996, the Fund's total return was
      -0.81 percent(1) (Class A shares at net asset value). In comparison, the
      market in general, as represented by the Lehman Brothers Municipal Bond
Index, returned -0.45 percent for the same period. Longer term, the Fund
generated a one-year total return of 6.67 percent(1) (Class A shares at net
asset value) through June 30, 1996. The Lehman Index is a broad-based, unmanaged
index of municipal bonds and does not reflect any commissions or fees that would
be paid by an investor purchasing the securities it represents. Please refer to
the chart on page three for additional Fund performance results.
    From an income perspective, the Fund's Class A shares ended the period with
an annualized dividend of $0.774 per share. The Fund continues to provide a
respectable level of tax-exempt income with a distribution rate of 5.09
percent(3) as of June 30, 1996--the equivalent of a 8.50 percent(4) taxable
distribution rate for investors in the 40.1 percent combined federal and state
income tax bracket.
 
   Q  WHAT IS YOUR OUTLOOK FOR THE MARKET IN THE MONTHS AHEAD?

   A  The New Jersey economy is generally sound, and we do not anticipate any
      significant changes in the management of the Fund. However, if the
      national economy continues to show signs of strong growth, we could see
some changes in market fundamentals:
- -   INFLATION has been holding at a low 2 to 3 percent range for some time now,
    but going forward, there is some concern that inflation could slowly creep
    upward, which could have a negative effect on the market.
- -   INTEREST RATES: We anticipate the Federal Reserve will remain in a neutral
    policy mode, but it may become necessary to tighten interest rates if the
    economy continues to strengthen.
- -   The positive ratio between LOWER SUPPLY AND HIGHER DEMAND should continue in
    the upcoming months, which is a stabilizing influence on municipal bond
    values. If there is a rally in bond prices, we could see an increase in
    refundings, which could bring more supply into the market.

1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital New Jersey Tax Free Income Fund (the "Fund") is
organized as a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust, and is registered as a non-diversified open-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to provide investors with a high
level of current income exempt from federal income tax and New Jersey gross
income tax, consistent with preservation of capital. The Fund commenced
investment operations on July 29, 1994.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made. As of June 30, 1996, there were no
when issued or delayed delivery purchase commitments.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the expected life of each
applicable security.

- --------------------------------------------------------------------------------
 
D. ORGANIZATIONAL EXPENSES--The Fund will reimburse Van Kampen American Capital
Distributors, Inc. or its affiliates (collectively "VKAC") for costs incurred in
connection with the Fund's organization in the amount of $120,000. These costs
are being amortized on a straight line basis over the 60 month period ending
July 28, 1999. Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") has agreed that in the event any of the initial shares of the Fund
originally purchased by VKAC are redeemed by the Fund during the amortization
period, the Fund will be reimbursed for any unamortized organizational expenses
in the same proportion as the number of shares redeemed bears to the number of
initial shares held at the time of redemption.
 
E. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income, if any, to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1995, the Fund had an accumulated capital loss
carryforward for tax purposes of $259,106, of which $11,885 and $247,221 will
expire on December 31, 2002 and 2003, respectively. Net realized gains or losses
may differ for financial and tax reporting purposes primarily as a result of
post October 31 losses which are not recognized for tax purposes until the first
day of the following fiscal year.
 
F. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Due to inherent differences in the recognition of certain
expenses under generally accepted accounting principles and federal income tax
purposes, the amount of distributable net investment income may differ between
book and federal income tax purposes for a particular period. These differences
are temporary in nature, but may result in book basis distribution in excess of
net investment income for certain periods.

    Certain legal expenses are paid to Skadden, Arps, Slate, Meagher & Flom,
counsel to the Fund, of which a trustee of the Fund is an affiliated person.
 
    For the six months ended June 30, 1996, the Fund recognized expenses of
approximately $5,900 representing VKAC's cost of providing cash management and
legal services to the Fund. All of this cost has been assumed by VKAC.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent for the Fund. For the six months ended
June 30, 1996, the Fund recognized expenses of approximately $2,900,
representing ACCESS's cost of providing transfer agency and shareholder services
plus a profit. All of this expense has been assumed by VKAC.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.
 
    At June 30, 1996, VKAC owned 100 shares each of Classes A, B and C.
 
3. CAPITAL TRANSACTIONS
 
The Fund has outstanding three classes of common shares, Classes A, B and C each

August 1, 1996
 
Dear Shareholder,
    As you may be aware, an agreement
was reached in late June for VK/AC
Holding, Inc., the parent company of
Van Kampen American Capital, Inc., to
be acquired by the Morgan Stanley
Group Inc. While this announcement
may appear commonplace in an
ever-changing financial industry, we
believe it represents an exciting
opportunity for shareholders of our
investment products.
    With Morgan Stanley's global
leadership in investment banking and
asset management and Van Kampen American Capital's reputation for competitive
long-term performance and superior investor services, together we will offer a
broader range of investment opportunities and expertise.
    The new ownership will not affect our commitment to pursuing excellence in
all aspects of our business. And, we expect very little change in the way your
mutual fund account is maintained and serviced.
    A proxy will be mailed to you shortly explaining the acquisition and asking
for your vote of approval. Please read it carefully and return your response for
inclusion in the shareholder vote. We value our relationship with you and look
forward to communicating more details of this transaction, which is anticipated
to be completed in November.
 
ECONOMIC REVIEW AND OUTLOOK
    The economy demonstrated an acceleration in growth during the six-month
reporting period. After a nominal 0.3 percent growth rate in the last quarter of
1995, GDP (the nation's gross domestic product) rose by 2.0 percent in this
year's first quarter. And, as anticipated, the economy grew by 4.2 percent in
the second quarter, partly reflecting a recovery from the effects of labor
strikes earlier in the year and extreme weather conditions across the country.
Upward momentum has been assisted by consumer spending, as indicated by a 5.6
percent rise in retail sales in the first five months of this year versus the
comparable 1995 period.
    In the manufacturing sector, economic reports, such as the National
Association of Purchasing Managers Index, suggested a continued rebound in
production from last winter's lower levels. In June, this index reached its
highest level since early 1995. Strong levels of exports and a replenishing of
inventories have helped support this momentum.
    Surprisingly healthy economic activity led to concerns that inflation may
rise and the Federal Reserve Board might tighten monetary policy. Inflation
remains modest, however, with consumer prices rising at about a 3 percent annual
rate over the past year. Meanwhile, the closely watched "core" Consumer Price
Index, which excludes volatile food and energy components, has risen year over
year at rates between 2.7 and 3.0 percent per year, with mid-1996 readings at a
moderate 2.7 percent. In general, recent reports have suggested an upward creep
in labor-related costs, while indicating that prices of many commodities have
begun to decline.
 
                                                           Continued on page two
 
                                        1
<PAGE>   220
 
    We anticipate that reasonably strong economic growth will continue during
the balance of 1996, albeit at more moderate rates than the second quarter's
swift pace. While we expect rates of inflation to remain near current levels,
the Fed may begin to lean toward greater restraint in its monetary policy in the
coming months. That suggests an upward bias for short-term interest rates and
for yields on long-term bonds to remain steady at current levels. Specifically,
we expect 10-year Treasury yields to trade within a range of 5.7 and 6.3
percent, particularly when compared to taxable investments.
 
MUNICIPAL MARKET REVIEW AND OUTLOOK
    We witnessed significant movement in municipal bond yields during the first
six months of 1996. Early in the period, the Fed lowered rates in order to
energize the economy, and bond prices increased. By late February, however, the
markets became concerned that the Fed could reverse its strategy direction and
raise rates. As a result, yields, as measured by the Bond Buyer 40 Municipal
Bond Index, rose from 5.6 percent to 6.0 percent during the period.
    We believe market conditions for municipal bonds are poised for improvement
in the second half of 1996. Three major factors contribute to our optimism:
- -   Near-term concerns about the implementation of a major tax reform have
    faded. In early 1996, the municipal market was wary of the growing political
    momentum for tax reform, which could have eroded the value of the market's
    tax-exempt status. However, the momentum slowed substantially and now
    appears to be on the back burner until after the 1996 presidential election.
    This has added stability to the market.
- -   For high-income households, tax-exempt bonds provide an attractive after-tax
    alternative. Municipal bond yields have elevated to a point where taxable
    equivalent yields range between 8.5 and 10 percent for investors in the 31
    percent tax bracket or higher.
- -   Recent volatility in the equity markets coupled with rising interest rates
    are leading individual investors, as well as institutions, to reexamine
    their allocation of assets. In general, this translates into an increased
    emphasis on fixed-income, which should lend support to the municipal market.
    Looking ahead, inflation fears and concerns about economic growth may
continue to influence the municipal bond market and fund performance results.
Nevertheless, we are optimistic that tax-exempt securities will produce
attractive results for investors during the remainder of 1996.
    Additional details about your Fund, including a question and answer section
with your portfolio management team, is provided in this report. We appreciate
your continued confidence in your investment with Van Kampen American Capital.

(1)Assumes reinvestment of all distributions for the period and does not include
payment of the maximum sales charge (4.75% for A shares) or contingent deferred
sales charge for early withdrawal (4% for B shares and 1% for C shares).
 
(2)Standardized total return. Assumes reinvestment of all distributions for the
period ended and includes payment of the maximum sales charge (A shares) or
contingent deferred sales charge for early withdrawal (B and C shares).
 
(3)Distribution rate represents the monthly annualized distributions of the Fund
at the end of the period and not the earnings of the Fund.
 
(4)Taxable equivalent calculations reflect a combined federal and state income
tax rate of 40.5% which takes into consideration the deductibility of individual
state taxes paid.
 
(5)SEC Yield is a standardized calculation prescribed by the Securities and
Exchange Commission for determining the amount of net income a portfolio should
theoretically generate for the 30-day period ending June 30, 1996. Had certain
expenses of the Fund not been assumed by VKAC, the SEC Yield would have been
3.86%, 3.37%, and 3.37% for Classes A, B and C, respectively, and total returns
would have been lower.
 
A portion of the interest income may be taxable for those Investors subject to
the federal alternative minimum tax (AMT).
 
See the Fund Performance section of the current prospectus. Past performance
does not guarantee future results. Investment return and net asset value will
fluctuate with market conditions. Fund shares, when redeemed, may be worth more
or less than their original cost.

                          PORTFOLIO MANAGEMENT REVIEW
           VAN KAMPEN AMERICAN CAPITAL NEW YORK TAX FREE INCOME FUND
 
We recently spoke with the management team of the Van Kampen American Capital
New York Tax Free Income Fund about the key events and economic forces that
shaped the markets during the first half of the Fund's fiscal year. The team
includes Dennis Pietrzak, portfolio manager, and Peter W. Hegel, executive vice
president for fixed-income investments. The following excerpts reflect their
views concerning the Fund's performance during the six-month period ended June
30, 1996.
   Q  WHAT EVENTS OR MARKET CONDITIONS HAD THE GREATEST IMPACT ON THE FUND
      DURING THE FIRST HALF OF THIS YEAR?
   A  Early in the year, indicators pointing to a stronger, expanding economy
      sparked concern over inflation and expectations that the Federal Reserve
      Board would increase short-term interest rates in order to keep the
economy from overheating. The prospect of higher rates was a concern to the
market, which responded by trading toward lower prices and higher yields.
    On the other hand, municipal market concerns that major tax reform proposals
may gain acceptance--and potentially erode the tax-exempt status associated with
municipals--eased in the first half of 1996. So, even though bond prices
generally declined, they did so to a lesser extent in the municipal market.
    The supply and demand relationship continued to be a positive influence on
the municipal bond market over the reporting period--supply remained low while
demand remained fairly strong. This helped support bond prices and partly offset
the negative effect that rising interest rates had on bond prices.
 
   Q  HOW WAS THE FUND'S PORTFOLIO STRUCTURED IN LIGHT OF
      THESE CONDITIONS?
   A  The Fund was structured with a duration of 8.4 years at the end of the
      period, which is slightly higher than the benchmark that we try to target
      over time. Duration is a measure of a portfolio's sensitivity to changes
in interest rates. The shorter the duration, the less sensitive the portfolio is
expected to be to interest rates. The Fund's average weighted maturity remained
at 18 years, which we feel offered the best overall balance between income and
total return performance.
    One of the biggest challenges that we faced was finding New York state
issues that offered relative value in the current low supply environment. The
majority of the Fund's assets (83.5 percent) were invested in securities of
investment-grade quality (BBB-rated or higher). The highest concentration of
holdings continues to be in healthcare at 22.8 percent. We believe healthcare is
attractive primarily because the majority of new issues have been from this
sector. Please refer to page four for Fund portfolio highlights.

<PAGE>   224
 
   Q  HOW DID THE FUND PERFORM DURING THE SIX MONTHS ENDED JUNE 30, 1996?
   A  For the six-month period ended June 30, 1996, the Fund's total return was
      -1.06 percent(1) (Class A shares at net asset value). By comparison, the
      market in general, as represented by the Lehman Brothers Municipal Bond
Index, returned - 0.45 percent over the same period. Longer term, the Fund
generated a one-year total return of 6.86 percent(1) (Class A shares at net
asset value) through June 30, 1996. The Lehman Index is a broad-based, unmanaged
index of municipal bonds and does not reflect any commissions or fees that would
be paid by an investor purchasing the securities it represents. Please refer to
the chart on page three for additional Fund performance results.
    At its current annualized dividend level of $0.798 per share, the Fund
generated a tax-free distribution rate of 5.25 percent(3) (Class A shares) as of
June 30, 1996. At this distribution rate, the Fund provides shareholders in the
40.5 percent combined federal and state income tax bracket with a yield
equivalent to a taxable investment earning 8.82 percent(4).
 
   Q  WHAT IS YOUR OUTLOOK FOR THE MUNICIPAL BOND MARKET IN THE UPCOMING MONTHS?
   A  The New York economy continues to improve, and we do not anticipate any
      significant changes in the management of the Fund. However, if the
      national economy continues to show signs of strong growth, we could see
      some changes in market fundamentals:
- -   INFLATION has been holding at a low 2 to 3 percent range for some time now,
    but going forward, there is some concern that inflation could slowly creep
    upward, which could have a negative effect on the market.
- -   INTEREST RATES: We anticipate the Federal Reserve will remain in a neutral
    policy mode, but it may become necessary to tighten interest rates if the
    economy continues to strengthen.
- -   The positive ratio between LOWER SUPPLY AND HIGHER DEMAND should continue in
    the upcoming months, which is a stabilizing influence on municipal bond
    values. If there is a rally in bond prices, we could see an increase in
    refundings, which could bring more supply into the market.

                           June 30, 1996 (Unaudited)
- --------------------------------------------------------------------------------
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
Van Kampen American Capital New York Tax Free Income Fund (the "Fund") is
organized as a series of the Van Kampen American Capital Tax Free Trust, a
Delaware business trust, and is registered as a non-diversified open-end
management investment company under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to provide investors with a high
level of current income exempt from federal, New York State and New York City
income taxes, consistent with preservation of capital. The Fund seeks to achieve
its investment objective by investing at least 80% of its assets in a portfolio
of New York municipal securities rated investment grade at the time of
investment. The Fund commenced investment operations on July 29, 1994.
 
    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
A. SECURITY VALUATION--Investments are stated at value using market quotations
or, if such valuations are not available, estimates obtained from yield data
relating to instruments or securities with similar characteristics in accordance
with procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of less than 60 days are valued at
amortized cost.
 
B. SECURITY TRANSACTIONS--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made. At June 30, 1996, there were no when
issued or delayed delivery purchase commitments.
 
C. INVESTMENT INCOME--Interest income is recorded on an accrual basis. Bond
premium and original issue discount on securities purchased are amortized over
the expected life of each applicable security.

                           June 30, 1996 (Unaudited)
- --------------------------------------------------------------------------------
 
D. ORGANIZATIONAL EXPENSES--The Fund will reimburse Van Kampen American Capital
Distributors, Inc. or its affiliates (collectively "VKAC") for costs incurred in
connection with the Fund's organization in the amount of $120,000. These costs
are being amortized on a straight line basis over the 60 month period ending
July 28, 1999. Van Kampen American Capital Investment Advisory Corp. (the
"Adviser") has agreed that in the event any of the initial shares of the Fund
originally purchased by VKAC are redeemed during the amortization period, the
Fund will be reimbursed for any unamortized organizational expenses in the same
proportion as the number of shares redeemed bears to the number of initial
shares held at the time of redemption.
 
E. FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income, if any, to its shareholders.
Therefore, no provision for federal income taxes is required.
 
    The Fund intends to utilize provisions of the Federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At December 31, 1995, the Fund had an accumulated capital loss
carryforward for tax purposes of $214,449, of which $116,418 and $98,031 will
expire on December 31, 2002 and 2003, respectively. Net realized gains or losses
may differ for financial and tax reporting purposes primarily as a result of
post October 31 losses which are not recognized for tax purposes until the first
day of the following fiscal year.
 
F. DISTRIBUTION OF INCOME AND GAINS--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Due to inherent differences in the recognition of certain
expenses under generally accepted accounting principles and federal income tax
purposes, the amount of distributable net investment income may differ between
book and federal income tax purposes for a particular period. These differences
are temporary in nature, but may result in book basis distribution in excess of
net investment income for certain periods.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
Under the terms of the Fund's Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Fund for an annual fee payable
monthly as follows:

    Certain legal expenses are paid to Skadden, Arps, Slate, Meagher & Flom,
counsel to the Fund, of which a trustee of the Fund is an affiliated person.
 
    For the six months ended June 30, 1996, the Fund recognized expenses of
approximately $5,600 representing VKAC's cost of providing cash management and
legal services to the Fund. All of this cost has been assumed by VKAC.
 
    ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Fund. For the six months ended
June 30, 1996, the Fund recognized expenses of approximately $3,700,
representing ACCESS' cost of providing transfer agency and shareholder services
plus a profit. All of this expense has been assumed by VKAC.
 
    Certain officers and trustees of the Fund are also officers and directors of
VKAC. The Fund does not compensate its officers or trustees who are officers of
VKAC.
 
    The Fund has implemented deferred compensation and retirement plans for its
trustees. Under the deferred compensation plan, trustees may elect to defer all
or a portion of their compensation to a later date. The retirement plan covers
those trustees who are not officers of VKAC.
 
    At June 30, 1996, VKAC owned 100 shares each of Classes A, B and C.
 
3. CAPITAL TRANSACTIONS
The Fund has outstanding three classes of common shares, Classes A, B and C each
with a par value of $.01 per share. There are an unlimited number of shares of
each class authorized.
