PRESIDENT'S MESSAGE

[Photo of Stephen E. Gibson]

Dear Shareholder:
During the six months ended May 31, 1999, the bond market experienced
considerable volatility. In early December 1998, continued fears of a global
recession resulted in a flight to quality that benefited bond performance.
Treasury securities, considered the safest bond investments, were the top
performers, but municipal bonds also posted solid returns. By the end of May
1999, several events reversed the trend. Global economies stabilized, and strong
U.S. economic growth in the last quarter of 1998 and the first quarter of 1999
renewed investors' inflation fears. Bond prices declined, driving interest rates
up across the board. Fortunately, municipal bonds were not hit as hard as
Treasurys on the way down.

Although the past six months presented a difficult environment for the bond
market, the Fund outperformed its peer group average, extending its one-, three-
and five-year track record in the top half of its Lipper category.(1) While past
performance cannot predict future results, it is important to keep a long-term
perspective when making investment decisions.

The following report will provide you with more specific information about your
Fund's performance and the strategies employed during the period. As always, we
thank you for choosing Colonial Tax-Exempt Fund and for giving us the
opportunity to serve your investment needs.

    Respectfully,

/s/ Stephen E. Gibson

    Stephen E. Gibson
    President
    July 15, 1999

O  BOND MARKET CONDITIONS WERE CHALLENGING.

   Long-term interest rates rose almost a full percentage point between December
   and May in response to renewed concern about the economy's strength and fears
   of potentially higher inflation. As yields rose, bond prices fell.

O  MUNICIPAL BONDS OUTPERFORMED TREASURYS AS INTEREST RATES ROSE.

   Within the tax-exempt market, bond prices moved in sync with the Treasury
   market during the past six months. While tax-exempt bonds gained less ground
   than Treasurys early on when interest rates were falling, municipal bonds
   outperformed the Treasury sector later in the period, losing less of their
   principal value as interest rates rose.

O  MARKET'S ANTICIPATION OF HIGHER INTEREST RATES WAS REFLECTED IN LOWER BOND
   PRICES.

   In May, Federal Reserve Board policy makers prepared investors for a rate
   increase later this year by switching from a neutral stance to one biased
   towards raising rates in the future. Bond prices fell in response and
   remained weak through the end of the period.

SEMIANNUAL REPORT: COLONIAL TAX-EXEMPT FUND

- --------------------------------------------------------------------------------
PORTFOLIO MANAGERS' REPORT
- --------------------------------------------------------------------------------

STRATEGY ADJUSTED TO RESPOND TO CHANGING MARKET CONDITIONS
We made several shifts in the Fund's investment strategy during the past six
months. First, we reduced the portfolio's interest rate sensitivity in response
to numerous reports detailing the economy's strength. Since those reports raised
concerns about inflation and potentially higher interest rates -- both negative
conditions for fixed-income investments -- we structured the Fund to be less
sensitive to interest rate changes. Second, we took advantage of widening credit
spreads, or the difference in yields between higher- and lower-quality
securities. In many cases, we felt that higher yields and lower prices did not
reflect the strengths of the underlying businesses. We invested selectively in
fundamentally sound, higher yielding bonds that provided the Fund with
attractive current income and price appreciation potential.

FUND'S PERFORMANCE REFLECTS STRATEGY
The Fund generated a six-month total return of 0.17% for Class A shares, based
on net asset value, modestly outperforming the average return of funds in the
Lipper General Municipal Debt category, which was 0.10% for the same period.
Because we structured the portfolio to be less sensitive to interest rate
changes, rising interest rates did not significantly affect relative performance
during the period. However, other factors combined to support the Fund's
performance. First, the portfolio's holdings of higher-coupon, lower-rated bonds
performed well. Second, a number of the Fund's housing bonds performed well.
Multi-family housing bonds outperformed many market sectors when interest rates
began rising. Housing issues typically perform best in weak market environments
because real estate owners are less likely to refinance and prepay their
mortgages. In addition, many of these issues benefited from strong regional real
estate markets -- healthy demand and high occupancy levels supported higher
rents and increased cash flows for project owners.

INVESTMENT ACTIVITY FOCUSED ON OPPORTUNISTIC PURCHASES
We took advantage of widening credit spreads to invest selectively in
well-managed high-yield companies with good growth prospects that have generated
strong cash flows and operate in attractive markets or service areas. These
investments included industrial revenue bonds, where repayment is backed by the
operations of a U.S. corporation. In addition, we took advantage of weak pricing
for bonds that have the potential to outperform when interest rates fall,
including non-callable bonds and zero-coupon bonds.

POSITIVE LONG-TERM MARKET OUTLOOK
We have a favorable long-term market outlook. Although we expect continued
interest rate volatility over the next several months as additional economic
reports are released, we regard the Federal Reserve Board's bias towards raising
short-term rates favorably. Although the market's initial reaction has been
negative, we believe that over a longer period, the Board's proactive move will
reduce the economy's growth rate and keep inflation in check, creating a more
positive investment environment for fixed-income securities.

                    SEC YIELDS ON 5/31/99

                    Class A                           4.29%

                    Class C                           3.90%
                    ----------------------------------------

The 30-day SEC yields reflect the portfolio's earning power net of expenses,
expressed as an annualized percentage of the public offering price per share. If
the Advisor or its affiliates had not waived certain Fund expenses, the SEC
yield would have 3.74% for Class C shares.

                    TAXABLE-EQUIVALENT SEC YIELDS ON 5/31/99

                    Class A                           7.10%

                    Class C                           6.46%
                    ----------------------------------------

Taxable-equivalent SEC yields are based on the maximum federal income tax rate
of 39.6%. This tax rate does not reflect the phase out of exemptions or the
reduction of otherwise allowable deductions which occur when Adjusted Gross
Income exceeds certain levels.

Quality and maturity breakdowns are calculated as a percentage of total
investments, including short-term obligations. Ratings shown in the quality
breakdowns represent the highest rating assigned to a particular bond by one of
the following respected rating agencies: Standard & Poor's, Moody's or Fitch.

Maturity breakdown is based on each security's effective maturity, which
reflects pre-refundings, mandatory puts and other conditions that affect a
bond's maturity.

Because the Fund is actively managed, there can be no guarantee the Fund will
continue to maintain these quality and maturity breakdowns in the future.

Past performance cannot predict future investment results. Returns and value of
an investment will vary, resulting in a gain or loss on sale. All results shown
assume reinvestment of distributions. Net asset value (NAV) returns do not
include sales charges or contingent deferred sales charges (CDSC). Public
offering price (POP) returns include the maximum sales charge of 4.75% for Class
A shares. The CDSC returns reflect the maximum applicable charges of 5% for one
year and 2% for five years for Class B shares and 1% for one year for Class C
shares.

Performance results reflect any voluntary waivers or reimbursement of Fund
expenses by the Advisor or its affiliates. Absent these waivers or reimbursement
arrangements, performance results would have been lower.

Class B and Class C share (newer class shares) performance information includes
returns of the Fund's Class A shares (the oldest existing fund class) for
periods prior to the inception of the newer class shares. These Class A share
returns are not restated to reflect any expense differential (e.g., Rule 12b-1
fees) between Class A shares and the newer class shares. Had the expense
differential been reflected, the returns for periods prior to the inception of
the newer class shares would have been lower.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

NOTE 1. INTERIM FINANCIAL STATEMENTS
In the opinion of management of Colonial Tax-Exempt Fund (the Fund), a series
of Liberty Trust IV, formerly Colonial Trust IV, the accompanying financial
statements contain all normal and recurring adjustments necessary for the fair
presentation of the financial position of the Fund at May 31, 1999, and the
results of its operations, the changes in its net assets and the financial
highlights for the six months then ended.

NOTE 2. ACCOUNTING POLICIES
ORGANIZATION
The Fund is a diversified portfolio of a Massachusetts business trust,
registered under the Investment Company Act of 1940, as amended, as an open-
end management investment company. The Fund's investment objective is to seek
as high a level of after-tax total return as is consistent with prudent risk,
by pursuing current income exempt from federal income tax and opportunities
for long-term appreciation from a portfolio primarily invested in investment-
grade municipal bonds. The Fund may issue an unlimited number of shares. The
Fund offers three classes of shares: Class A, Class B and Class C. Class A
shares are sold with a front-end sales charge and a 1.00% contingent deferred
sales charge on redemptions made within eighteen months on an original
purchase of $1 million to $5 million. Class B shares are subject to an annual
distribution fee and a contingent deferred sales charge. Class B shares will
convert to Class A shares when they have been outstanding approximately eight
years. Class C shares are subject to a contingent deferred sales charge on
redemptions made within one year after purchase and an annual distribution
fee.

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. The following is a summary
of significant accounting policies that are consistently followed by the Fund
in the preparation of its financial statements.

SECURITY VALUATION AND TRANSACTIONS
Debt securities generally are valued by a pricing service based upon market
transactions for normal, institutional-size trading units of similar
securities. When management deems it appropriate, an over-the-counter or
exchange bid quotation is used.

Options are valued at the last reported sale price, or in the absence of a
sale, the mean between the last quoted bid and asking price.

Futures contracts are valued based on the difference between the last sale
price and the opening price of the contract.

Short-term obligations with a maturity of 60 days or less are valued at
amortized cost.

Portfolio positions for which market quotations are not readily available are
valued at fair value under procedures approved by the Trustees.

Security transactions are accounted for on the date the securities are
purchased, sold or mature.

Cost is determined and gains (losses) are based upon the specific
identification method for both financial statement and federal income tax
purposes.

The Fund may trade securities on other than normal settlement terms. This may
increase the risk if the other party to the transaction fails to deliver and
causes the Fund to subsequently invest at less advantageous prices.

DETERMINATION OF CLASS NET ASSET VALUES AND FINANCIAL HIGHLIGHTS
All income, expenses (other than the Class B and Class C distribution fees),
and realized and unrealized gains (losses), are allocated to each class
proportionately on a daily basis for purposes of determining the net asset
value of each class.

Class B and Class C per share data and ratios are calculated by adjusting the
expense and net investment income per share data and ratios for the Fund for
the entire period by the distribution fees for Class B and Class C shares
only.

FEDERAL INCOME TAXES
Consistent with the Fund's policy to qualify as a regulated investment company
and to distribute all of its taxable and tax-exempt income, no federal income
tax has been accrued.

INTEREST INCOME, DEBT DISCOUNT AND PREMIUM
Interest income is recorded on the accrual basis. Original issue discount is
accreted to interest income over the life of a security with a corresponding
increase in the cost basis; market discount is not accreted. Premium is
amortized against interest income with a corresponding decrease in the cost
basis.

DISTRIBUTIONS TO SHAREHOLDERS
The Fund declares and records distributions daily and pays monthly.

The amount and character of income and gains to be distributed are determined
in accordance with income tax regulations which may differ from generally
accepted accounting principles. Reclassifications are made to the Fund's
capital accounts to reflect income and gains available for distribution (or
available capital loss carryforwards) under income tax regulations.

NOTE 3. FEES AND COMPENSATION PAID TO AFFILITES
MANAGEMENT FEE
Colonial Management Associates, Inc. (the Advisor) is the investment Advisor
of the Fund and furnishes accounting and other services and office facilities
for a monthly fee based on each Fund's pro-rata portion of the combined
average net assets of the Fund, Colonial Tax-Exempt Insured Fund and Colonial
High Yield Municipal Fund as follows:

         AVERAGE NET ASSETS                     ANNUAL FEE RATE
         ------------------                     ---------------
First $1 billion                                     0.60%
Next $2 billion                                      0.55%
Next $1 billion                                      0.50%
Over $4 billion                                      0.45%

BOOKKEEPING FEE
The Advisor provides bookkeeping and pricing services for $27,000 per year
plus a percentage of the Fund's average net assets as follows:

AVERAGE NET ASSETS                              ANNUAL FEE RATE
- ------------------                              ---------------
First $50 million                                  No charge
Next $950 million                                   0.035%
Next $1 billion                                     0.025%
Next $1 billion                                     0.015%
Over $3 billion                                     0.001%

TRANSFER AGENT
Liberty Funds Services, Inc. (the Transfer Agent), an affiliate of the
Advisor, provides shareholder services for a monthly fee equal to 0.13%
annually of the Fund's average net assets and receives reimbursement for
certain out-of-pocket expenses.

UNDERWRITING DISCOUNTS, SERVICE AND DISTRIBUTION FEES
Liberty Funds Distributor, Inc. (the Distributor), a subsidiary of the
Advisor, is the Fund's principal underwriter. During the six months ended May
31, 1999, the Fund has been advised that the Distributor retained net
underwriting discounts of $686,871 on sales of the Fund's Class A shares and
received contingent deferred sales charges (CDSC) of none, $159,786 and
$1,460, on Class A, Class B and Class C share redemptions, respectively.

The Fund has adopted a 12b-1 plan which requires the payment of a service fee
to the Distributor equal to 0.25% annually of the Fund's net assets as of the
20th of each month. The plan also requires the payment of a distribution fee
to the Distributor equal to 0.75% annually of the average net assets
attributable to Class B and Class C shares only. The Distributor has
voluntarily agreed to waive a portion of the Class C share distribution fee so
that it will not exceed 0.60% annually.

The CDSC and the fees received from the 12b-1 plan are used principally as
repayment to the Distributor for amounts paid by the Distributor to dealers
who sold such shares.

OTHER
The Fund pays no compensation to its officers, all of whom are employees of
the Advisor.

The Fund's Trustees may participate in a deferred compensation plan which may
be terminated at any time. Obligations of the plan will be paid solely out of
the Fund's assets.

NOTE 4. PORTFOLIO INFORMATION
INVESTMENT ACTIVITY
During the six months ended May 31, 1999, purchases and sales of investments,
other than short-term obligations, were $438,567,272 and $529,492,564,
respectively.

Unrealized appreciation (depreciation) at May 31, 1999, based on cost of
investments for federal income tax purposes was approximately:

  Gross unrealized appreciation                                 $126,969,000
  Gross unrealized depreciation                                 (24,586,000)
                                                                ------------
  Net unrealized appreciation                                   $102,383,000
                                                                ============

OTHER
The Fund has greater than 10% of its net assets at May 31, 1999 invested in
New York.

There are certain risks arising from geographic concentration in any state.
Certain revenue or tax related events in a state may impair the ability of
certain issuers of municipal securities to pay principal and interest on their
obligations.

The Fund may focus its investments in certain industries, subjecting it to
greater risk than a fund that is more diversified.

The Fund may purchase or sell municipal and Treasury bond futures contracts
and purchase and write options on futures. The Fund will invest in these
instruments to hedge against the effects of changes in the value of portfolio
securities due to anticipated changes in interest rates and/or market
conditions, for duration management, or when the transactions are economically
appropriate to the reduction of risk inherent in the management of the Fund
and not for trading purposes. The use of futures contracts and options
involves certain risks, which include (1) imperfect correlation between the
price movement of the instruments and the underlying securities, (2) inability
to close out positions due to different trading hours or the temporary absence
of a liquid market for either the instrument or the underlying securities or
(3) an inaccurate prediction by the Advisor of the future direction of
interest rates. Any of these risks may involve amounts exceeding the amount
recognized in the Fund's Statement of Assets and Liabilities at any given
time.

NOTE 5. LINE OF CREDIT
The Fund may borrow up to 33 1/3% of its net assets under a line of credit for
temporary or emergency purposes. Any borrowings bear interest at one of the
following options determined at the inception of the loan: (1) federal funds
rate plus  1/2 of 1%, (2) the lending bank's base rate or (3) IBOR offshore
loan rate plus  1/2 of 1%. There were no borrowings under the line of credit
during the six months ended May 31, 1999.

BECAUSE NO SINGLE INVESTMENT MANAGER CAN BE ALL THINGS TO ALL INVESTORS.(SM)

[Graphic Omitted]   Colonial has long been a recognized leader in fixed-income
                    investing. In addition, Colonial has distinguished itself
                    with both a traditional value and a more contemporary
                    approach to equity investing.

[Graphic Omitted]   Crabbe Huson's contrarian investment style seeks long-term
                    performance by investing in stocks from high-quality,
                    out-of-favor companies. This risk-averse strategy
                    capitalizes on the potential of these companies to regain
                    market popularity.

[Graphic Omitted]   LAMCO brings institutional money management to individual
                    investors through a disciplined multi-manager investment
                    process that seeks to deliver consistent long-term returns.

[Graphic Omitted]   A leader in Asian investing(TM), Newport has an unparalleled
                    knowledge of Asian economies, business and culture.

[Graphic Omitted]   Stein Roe's growth management style emphasizes companies
                    with the ability to create, maintain and grow earnings in
                    different market environments.

       BOSTON   o   CHICAGO   o   NEWYORK   o   PORTLAND   o   SAN FRANCISCO

That's why each of these affiliated managers has excelled in a particular
investment style. These managers not only specialize in a distinct investment
style, they hold a passion for their style along with a demonstrated track
record.

Each of these managers is a member of the Liberty Financial Companies (NYSE: L),
a diversified asset accumulation and management organization with approximately
$61 billion in assets under management for more than 1.7 million investors. Many
of the affiliated managers' products are offered by prospectus through Liberty
Funds Distributor, Inc.

blends the complementary disciplines of different managers into a well-balanced
program tailored to your goals.
