DEAR SHAREHOLDER,
 
The agreement between the White House and Republican leaders in Congress to
balance the federal budget has effectively ended the market correction that
began in the first quarter. Such sudden progress on balancing the budget, an
initiative that the bond market was anticipating resolution on more than one
year ago, is positive news.

  The next several weeks will find Congress and the Clinton administration
negotiating toward a final agreement. Unlike previous failed proposals that
sought to balance the budget principally by increasing income taxes, the current
plan -- which starts from the base of a relatively small deficit -- proposes to
slow the growth of federal spending. As such, its prospects are promising.

  Natural skeptics are waiting to see specific legislation to see if the
agreement has teeth. While we are optimistic, we need to temper our enthusiasm.
Much of the good news associated with a balanced budget was quickly discounted
in the higher prices in the stock and bond markets.

  Of particular interest to equity investors is the agreement to reduce the
maximum tax rate on capital gains. Although details of the reduction are yet to
be known, the prospect of more favorable tax treatment on gains will have the
short-term effect of supporting stocks -- investors can be expected to postpone
selling until they can qualify for the lower tax rate. With equity sales
essentially "frozen" until the effective date is known, the stock market should
have a considerable underpinning. Once an effective date is determined, we would
expect the pent-up selling to occur once that date is reached. However, then we
shall enjoy the long-term positive effect of the lower tax rate on gains.

  Talk of a balanced budget has shifted the spotlight away from the Federal
Reserve Board's upward pressure on interest rates. Having declined to raise
rates in May, the Fed may still act again at a later date. However, this action
may be the last for a while because the economy seems to be slowing down in the
second quarter, after the rapid 5.6 percent growth in the first quarter of the
year. An economic slowdown would reduce the threat of inflation and reduce the
need for further rate hikes by the Fed.

  In fact, a review of the standard measures of the economy shows little to be
concerned about. As has been the pattern for more than five years, a few strong
quarters followed by a few weak quarters have produced an overall 2 percent to 3
percent rate of growth in gross domestic product (GDP). Job creation and the
unemployment rate are consistent with a moderately expanding economy. Corporate
profits continue to grow at an expected 4 to 5 percent rate in 1997. The
Consumer Price Index continues to track at a 2.5 percent to 3.0 percent rate.

  Just as we see a limited downside to today's rising interest rate environment,
so is there a limited upside in the near future. The effect of higher rates will
have to work itself through the economy. Higher rates have significant
implications for corporate profitability, debt issuance, credit extension and
international trade. Post-correction cash flows into the financial markets will
be a subject of great scrutiny. One of the factors driving the stock market to
its recent all-time high was the unprecedented high level of investment through
mutual funds, 401(k)s and qualified contribution plans. It is realistic to
expect that, on the margin, some of that cash will find a home in short-term,
liquid investments while the stock market sorts itself out.

  Leadership in the stock market has been quite narrow and concentrated for the
past six months in large, multinational companies with familiar consumer brand
names. The recent rally after the announcement of a balanced budget agreement
suggests that once monetary policy is also more certain, leadership may broaden
to include small capitalization stocks.

  Higher interest rates are, of course, anathema to the fixed-income market.
However, bond investors in the last few weeks have been cheered by the balanced
budget proposal and by expectations that interest rates would not go much
higher. We expect the bond market to trade in a very narrow range -- with long-

ECONOMIC GUIDEPOSTS

Economic activity is a key influence on investment performance and shareholder
decision-making. Periods of recession or boom, inflation or deflation, credit
expansion or credit crunch have a significant impact on mutual fund
performance.

        The following are some significant economic guideposts and their
investment rationale that may help your investment decision-making. The
10-year Treasury rate and the prime rate are prevailing interest rates. The
other data report year-to-year percentage changes.

term interest rates no lower than 6.75 percent and no higher than 7.25 percent.
One positive effect of the stock market correction was the widening of spreads
available on high yield bonds. As a consequence, high yield bonds today are more
reasonably priced.

  A natural response to increased volatility in the U.S. equity market is to
look abroad. In fact, the valuations of many international markets are more
attractive than the U.S. However, the weak German and Japanese economies make it
difficult to identify many exciting near-term opportunities without careful
research.

  Our recommendation to shareholders is to stay the course and to fight the
temptation to try to time when and where you should be invested. Financial
assets react much quicker today to events. Volatility has returned to the market
and with it heightened uncertainty. Now is the time to rely on your financial
representative for the expertise and the long-term investing discipline that he
or she can provide.

  With this commentary as an economic backdrop, we encourage you to read the
following detailed report of your fund, including an interview with your fund's
portfolio management. Thank you for your continued support. We appreciate the
opportunity to serve your investment needs.

PERFORMANCE UPDATE

[MIER PHOTO]
            
CHRIS MIER JOINED ZURICH KEMPER INVESTMENTS, INC. IN 1986 AND IS NOW SENIOR VICE
PRESIDENT AND PORTFOLIO MANAGER OF KEMPER MUNICIPAL BOND FUND AND KEMPER
INTERMEDIATE MUNICIPAL BOND FUND. MIER RECEIVED A B.A. DEGREE IN ECONOMICS FROM
THE UNIVERSITY OF MICHIGAN AND RECEIVED AN M.M. IN FINANCE FROM KELLOGG GRADUATE
SCHOOL OF MANAGEMENT AT NORTHWESTERN UNIVERSITY. HE IS A CHARTERED FINANCIAL
ANALYST.

THE VIEWS EXPRESSED IN THIS REPORT REFLECT THOSE OF THE PORTFOLIO MANAGER ONLY
THROUGH THE END OF THE PERIOD OF THE REPORT, AS STATED ON THE COVER. THE
MANAGER'S VIEWS ARE SUBJECT TO CHANGE AT ANY TIME, BASED ON MARKET AND OTHER 
CONDITIONS.

FOR MOST OF THE SIX-MONTH REPORTING PERIOD, THE MUNICIPAL MARKET FOCUSED ON
WHETHER OR NOT AN INTEREST RATE INCREASE BY THE FEDERAL RESERVE BOARD WOULD
OCCUR. THE MARKET'S QUESTION WAS ANSWERED IN MARCH WHEN THE FED INCREASED
SHORT-TERM RATES BY 0.25 PERCENT. PORTFOLIO MANAGER CHRIS MIER EXPLAINS HOW THE
FUNDS IN KEMPER NATIONAL TAX-FREE INCOME SERIES PERFORMED IN THE UNCERTAIN
MARKET AND HOW HE PREPARED THE FUNDS FOR THE RATE INCREASE.
 
Q    HOW DID THE FUNDS PERFORM DURING THE FIRST SIX MONTHS OF THE FISCAL YEAR?
     
A     The funds performed relatively well -- the Class A shares (unadjusted for
sales charge) of both outperformed the average six-month returns of their
respective Lipper Analytical peer groups (general municipal debt and
intermediate municipal debt categories). Most of the funds' returns reflected
income from the bonds in the portfolios with some level of price appreciation.
 
 
Q    MUNICIPAL BOND YIELDS HAVE FLUCTUATED QUITE A BIT DURING THE LAST SIX
MONTHS. WHAT IMPACT DID THIS HAVE ON THE MARKET?
 
A    During the first five months of the period, yields in the municipal market
fluctuated, but tended to be range-bound. At the end of February, yields were
somewhat lower than they had been at the start of the period. This had a
modestly positive effect on prices of municipal securities.

  The rise and fall of interest rates was partly based on the market's changing
expectations about whether or not the Federal Reserve Board (the Fed) would move
to raise short-term interest rates. It was assumed that the Fed would raise
short-term rates if there was an indication of the economy growing too quickly
and a possible emergence of inflation. We witnessed swings in the market
throughout the period on the heels of sometimes conflicting economic reports.
However, in March, with accumulating evidence of strong first quarter growth,
the Fed did raise short-term interest rates by 0.25 percent. In reaction to this
tightening, market yields rose and overall bond performance suffered, erasing
some of the gains achieved earlier in the period. The municipal bond market did,
however, outperform the Treasury bond market as interest rates rose.
 
 
Q    WHEN DID YOU BEGIN TO ANTICIPATE THE FEDERAL RESERVE BOARD INTERVENTION?
 
                        
A    Throughout the period, we closely monitored economic data releases and
managed the funds more defensively as time progressed.
 
  In January, we began to believe that growth in the economy would exceed market
expectations and we were concerned about the potential for wage inflation.
Therefore, we began to shorten the durations of the
 


                                                                             5

funds to prepare for any rise in rates. Remember, the shorter a fund's duration,
the less sensitive it is to interest rate changes. As a result of the funds'
shorter durations, they were able to outperform the average of their peers as
interest rates jumped in March.
 
 
Q    BESIDES ALTERING DURATION, WHAT OTHER TYPES OF ADJUSTMENTS DID YOU MAKE TO
THE FUNDS?
 

A    In addition to duration adjustments, we added A-rated and BBB-rated bonds
on a selective basis. These bonds offered higher coupon rates than some of the
funds' higher quality and insured issues. We also continued to focus on
maintaining or improving call protection on issues within the portfolios.
 
  We also continued to favor essential service revenue bonds--bonds used to
finance basic governmental services such as water and sewers, transportation and
education among other things.
 
  
Q    ARE MUNICIPAL BOND FUNDS A GOOD INVESTMENT IN THE CURRENT ECONOMIC
ENVIRONMENT?
 

A    Municipal bonds may play an important role in rounding out a
well-diversified portfolio of investments. The tax-exempt income that municipal
bond funds provide could be especially helpful now as many investors may be
under-invested in tax-exempt assets. Municipal bonds and equities are both
important components of a balanced portfolio. If your exposure to municipal
bonds has declined on a relative basis, now may be the right time to review your
long-term goals and rebalance your portfolio of investments.
 
  
Q    WHAT'S YOUR OUTLOOK FOR THE MUNICIPAL MARKET?
 
 
A    We anticipate that in order for the Fed to slow growth to its target rate
of around 2 1/2 percent, it may need to continue to increase short-term rates.
This may rattle the bond market, but if the rate hikes are successful in slowing
the economy and warding off inflation, the moves will ultimately be positive for
bond investors. Municipal supply should remain close to 1996 levels or even
below. We plan to manage the funds cautiously until interest rates stabilize.


TERMS TO KNOW
 
DURATION Duration is a measure of the interest rate sensitivity of a
fixed-income investment or portfolio. The longer the duration, the greater the
interest rate risk.
 
REVENUE BOND INDEX (RBI) RBI is the average yield on 25 revenue bonds with
30-year maturities compiled by The Bond Buyer, a newspaper that covers the
municipal bond market.
 
TOTAL RETURN A fund's total return figure measures both the net investment
income and any realized and unrealized appreciation or depreciation of the
underlying investments in its portfolio for the period. Total return assumes the
reinvestment of all dividends and it represents the aggregate percentage or
dollar value change over the period.
 
YIELD A fund's yield is a measure of the net investment income per share earned
over a specific one month or 30-day period expressed as a percentage of the
maximum offering price of the fund's shares at the end of the period.

1    DESCRIPTION OF THE
     FUNDS                   The Kemper National Tax-Free Income Series (the
                             Trust) is an open-end, management investment
                             company comprised of Kemper Municipal Bond Fund
                             (Municipal Fund) and Kemper Intermediate Municipal
                             Bond Fund (Intermediate Municipal Fund). The Trust
                             is organized as a business trust under the laws of
                             Massachusetts.
 
                             The Funds offer four classes of shares. Class A
                             shares are sold to investors subject to an initial
                             sales charge. Class B shares are sold without an
                             initial sales charge but are subject to higher
                             ongoing expenses than Class A shares and a
                             contingent deferred sales charge payable upon
                             certain redemptions. Class B shares automatically
                             convert to Class A shares six years after issuance.
                             Class C shares are sold without an initial sales
                             charge but are subject to higher ongoing expenses
                             than Class A shares and a contingent deferred sales
                             charge payable on certain redemptions within one
                             year of purchase. Class C shares do not convert
                             into another class. Class I shares are offered to a
                             limited group of investors, are not subject to
                             initial or contingent deferred sales charges and
                             have lower ongoing expenses than other classes.
                             Differences in class expenses will result in the
                             payment of different per share income dividends by
                             class. All shares of each Fund have equal rights
                             with respect to voting, dividends and assets,
                             subject to class specific preferences.

2    SIGNIFICANT
     ACCOUNTING POLICIES     INVESTMENT VALUATION. Investments are stated at
                             value. Fixed income securities are valued by using
                             market quotations, or independent pricing services
                             that use prices provided by market makers or
                             estimates of market values obtained from yield data
                             relating to instruments or securities with similar
                             characteristics. Exchange traded financial futures
                             and options are valued at the settlement price
                             established each day by the board of trade or
                             exchange on which they are traded. Over-the-counter
                             traded options are valued based upon prices
                             provided by market makers. Other securities and
                             assets are valued at fair value as determined in
                             good faith by the Board of Trustees.
 
                             INVESTMENT TRANSACTIONS AND INVESTMENT INCOME.
                             Investment transactions are accounted for on the
                             trade date (date the order to buy or sell is
                             executed). Interest income is recorded on the
                             accrual basis and includes premium and original
                             discount amortization on fixed income securities.
                             Realized gains and losses from investment
                             transactions are reported on an identified cost

                             EXPENSES. Expenses arising in connection with a
                             specific Fund are allocated to that Fund. Other
                             Trust expenses are allocated between the Funds in

                             (plus an initial sales charge on most sales of
                             Class A Shares). Proceeds payable on redemption of
                             Class B and Class C shares will be reduced by the
                             amount of any applicable contingent deferred sales
                             charge. On each day the New York Stock Exchange is
                             open for trading, the net asset value per share is
                             determined as of the earlier of

                             determined separately for each class by dividing

                             available to investment companies for the six

                             shares for which payment has been received. Income
                             dividends are distributed monthly. Net realized
                             capital gains, if any, will be distributed at least
                             annually. Dividends are determined in accordance
                             with income tax principles which may treat certain
                             transactions differently than generally accepted
                             accounting principles.

     FINANCIAL FUTURES
     CONTRACTS               The Funds have entered into exchange traded
                             financial futures contracts on U.S. Treasury
                             securities in order to help protect themselves from
                             anticipated market conditions and, as such, bear
                             the risk that arises from entering into these
                             contracts.
 
                             At the time a Fund enters into a futures contract,
                             it is required to make a margin deposit with its
                             custodian. Subsequently, gain or loss is recognized
                             and payments are made on a daily basis between the
                             Fund and its broker as the market value of the
                             futures contract fluctuates. At March 31, 1997, the
                             market value of assets pledged by the Funds to
                             cover margin requirements for open futures
                             positions was $5,829,000 and $62,000 for the
                             Municipal Fund and the Intermediate Municipal Fund,
                             respectively. The Funds also had liquid securities
                             in their portfolios in excess of the face amount of
                             the following short Treasury Note futures open at
                             March 31, 1997:
