DEAR SHAREHOLDER:
 
Once again, investors experienced extreme market volatility in the month of
October. Unlike the October corrections of 1987 and 1989, this year's market
drop occurred at a time when the United States economy is remarkably healthy and
resilient. As we have noted, the U.S. economy has been moving forward for
several years with an alternating fast/slow pace that has proven successful in
removing whatever excesses build from quarter to quarter. As a consequence,
interest rates and the rate of inflation are both low and stable. Moreover, the
federal budget deficit has been reduced to such an extent that discussion has
now turned to what the government should do with a projected surplus in 1998.
 
     Fortunately, no part of our strong economic foundation was shaken by the
market correction. If anything, the correction provided a short-lived and
relatively painless lesson about the vulnerability of a highly valued market.
When markets are high, everything -- economic news, corporate earnings and
liquidity -- must go right. When markets are high - as our equity market has
been for most of this year - they are vulnerable to relatively minor
disappointments.
 
     As you have read, of course, the direct source of the October correction 
was Southeast Asia, where the world's highest growth economies had been
stumbling since the summer. These economies had become overextended, banks ran
into trouble with bad loans and the local governments failed to take prompt
action. The result was a domino effect of competitive devaluations of
currencies, crashing markets and political chaos.
        
     But while Southeast Asia produced the event that led to the mini-panic in 
the U.S. equity market - resulting in a 7 percent loss on October 27 -- the
world quickly looked to the U.S. for solutions. When the U.S. market quickly
rebounded, other markets became less volatile. Considering U.S. economic
fundamentals and the relatively small effect that Southeast Asian problems have
on U.S. companies as a whole, rational investors had to expect our market to
bounce back. In fact, if the U.S. equity market had not been so highly valued,
we would have expected the market's reaction to the Asian problems to be quite
muted. For instance, if the Dow Jones Industrial Average had been closer to
7000 than to 8000, we would have expected that the market would have dropped
only slightly.
        
     But as we have said before, today's markets move very fast. We experienced 
in one day the kind of correction that we used to experience over a six-month
period. At this writing, the U.S. equity market remains very volatile. We expect
that condition to continue, as volatility is a factor of higher valued markets.
Despite what the last few years may have suggested, markets do not go in just
one direction.
 
     Our recent experience supported many of the basic tenets of investing:
 
     - Invest for the long term and don't react to the short-term noise. 
       Investors who got hurt in the October correction were those who had
       borrowed the money they invested and were forced to sell at low prices.
       Investors who were able to remain invested and did, lost only some of
       their above-average gain for  the year.
        
     - Diversification helps reduce overall portfolio risk. Government 
       securities investors, for example, found the bond market to be a safe
       haven as the bond market rallied during the stock market correction.
        
     - Investing abroad is complex and requires expert advice. Currency 
       valuations, in particular, can have a significant effect on investment 
       returns.
 
     Our forecast for the next several months calls for moderate economic 
growth, stable interest rates and controlled inflation. While we cannot rule
out the possibility of another market event that would add to the excitement of
equity investing, we would expect the U.S. market to again demonstrate its
resiliency.

PERFORMANCE UPDATE

CHRIS MIER JOINED ZURICH KEMPER INVESTMENTS, INC. IN 1986 AND IS NOW SENIOR VICE
PRESIDENT AND PORTFOLIO MANAGER OF KEMPER NATIONAL TAX-FREE INCOME SERIES. MIER
RECEIVED A BACHELOR'S DEGREE IN ECONOMICS FROM THE UNIVERSITY OF MICHIGAN AND
WENT ON TO RECEIVE A MASTER'S OF MANAGEMENT DEGREE 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 THE FISCAL YEAR ENDED SEPTEMBER 30, 1997, A YEAR WITH UNCHARACTERISTICALLY
LOW INFLATION DESPITE MODERATE ECONOMIC GROWTH, KEMPER MUNICIPAL BOND FUND AND
KEMPER INTERMEDIATE MUNICIPAL BOND FUND BENEFITED FROM A RELATIVELY RANGE-BOUND
INTEREST RATE ENVIRONMENT. PORTFOLIO MANAGER CHRIS MIER EXPLAINS HOW THE 
PORTFOLIOS WERE ADJUSTED TO TAKE ADVANTAGE OF THIS CLIMATE.

Q     DURING THE FUNDS' FISCAL YEAR, THE FEDERAL RESERVE BOARD (THE FED) RAISED
SHORT-TERM INTEREST RATES. HOW DID THAT AND OTHER ECONOMIC EVENTS IMPACT THE
PERFORMANCE OF MUNICIPAL BONDS DURING THE PERIOD?
 
A     Municipal bonds performed relatively well during the 12-month period. The
Fed did raise interest rates but the impact of the tightening on the municipal
market was brief and minimal. Here's a look at that and other major events which
shaped the market's performance.
 
      At the start of the fiscal year, October 1, 1996, there was some political
uncertainty about the potential outcome of the presidential and congressional
elections. Investors feared the Republican party might lose control of Congress
and reduce the likelihood of a balanced budget agreement in 1997. Investment
markets rallied, however, with news that Republicans maintained control of
Congress. Some market participants intimated that the election outcome was
evidence of the public's desire for a true "checks and balances" government.
 
      The bullish environment began to change in December, when Federal Reserve
Board Chairman Alan Greenspan implied in passing that financial assets might be
overvalued. This shook the market and caused yields to rise and securities
prices to fall. Early in 1997, strong economic reports surfaced and Greenspan
reiterated his concern about the values of securities and about the potential
for a rise in wage inflation. In what was considered to be a preemptive move at
keeping inflation in check, the Fed tightened short-term rates by 0.25 percent
in late March.
 
      While economic growth remained somewhat strong even after the Fed 
tightening, inflation remained uncharacteristically low. The municipal market 
along with the broader fixed-income market began recouping losses experienced 
with the Fed's interest rate increase as inflation fears continued to be 
unconfirmed. For the remainder of the fiscal period, market yields fluctuated 
with the release of varying economic data but remained relatively range-bound.
Inflation never became problematic and bonds performed positively.
 
Q     DID THIS FLUCTUATION IN MARKET YIELDS AFFECT THE PERFORMANCE OF THE FUNDS?
 
A     Yields fluctuated with the markets' changing views on the direction of
economic growth and inflation. However, the fluctuations were not dramatic by
historical standards. In fact, the Bond Buyer 25-Bond Revenue Index-- a gauge of
municipal bond interest rates--fluctuated by less than one percent (65 basis
points) during the period. The index was at its period high for the weeks April
3 and April 10, 1997, at 6.14 percent and dropped to its lowest (5.49 percent)

                                                                              5

PERFORMANCE UPDATE
 
on July 31, 1997. The tightness of the yield range provided for relatively
stable bond prices throughout the fiscal year compared with previous fiscal
years.
 
Q     WHAT TYPES OF ADJUSTMENTS DID YOU MAKE TO THE FUNDS IN THIS RANGE-BOUND
RATE ENVIRONMENT?
 
A     We looked for ways to increase income without significantly increasing the
funds' risk exposure. One way we did this was by selectively choosing A and BBB
rated bonds, which offer higher coupon rates than some of the funds' higher
quality and insured issues.
 
Q     WERE THERE ANY OTHER SIGNIFICANT ADJUSTMENTS MADE TO THE FUNDS?
 
A     We maintained duration in a much tighter band, which was more compatible
with the tighter prevailing rate range. Remember, 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.
 
Q     WHAT CAN YOU TELL US ABOUT THE LEVEL OF SUPPLY AND DEMAND IN THE MARKET?
 
A     Year-to-date new issuance has been slightly higher in 1997 than in 1996.
New issuance volume through September 1997 was $153.5 billion compared with
$130.6 billion for the same period in 1996, according to THE BOND BUYER. Demand
for municipal issues came mainly from property and casualty companies and
individuals buying direct.
 
Q     WERE THERE ANY SECTORS THAT PERFORMED ABOVE YOUR EXPECTATIONS?
 
A     The transportation sector performed well during the period. The stronger
economy encouraged increased travel by the public, helping toll road issues.
Toll road bonds are held by the funds.
 
Q     ARE MUNICIPAL BOND FUNDS A GOOD INVESTMENT IN THE CURRENT ECONOMIC
ENVIRONMENT?
 
A     Municipal bonds can play an important role in rounding out a
well-diversified portfolio of investments. The tax-exempt income that municipal
bond funds provide may 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 municipals 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 IS YOUR OUTLOOK FOR THE MUNICIPAL MARKET?
 
A     Municipals are attractively valued in this market environment. Demand is
likely to continue to come mainly from the property and casualty industry as
well as individuals. Mutual fund demand for municipal bonds should pick up as
individuals who have accumulated wealth in the equity market attempt to maintain
or protect that wealth in a less risky type of investment.


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.  

BOND REVENUE INDEX This index is the average yield on 25 revenue bonds with
30-year maturities compiled by THE BOND BUYER, a newspaper that reports on 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.

REPORT OF INDEPENDENT AUDITORS
 
THE BOARD OF TRUSTEES AND SHAREHOLDERS
KEMPER NATIONAL TAX-FREE INCOME SERIES
 
  We have audited the accompanying statement of assets and liabilities,
including the portfolios of investments, of the Kemper Municipal Bond Fund and
Kemper Intermediate Municipal Bond Fund, comprising the Kemper National Tax-Free
Income Series (the Trust) as of September 30, 1997, the related statements of
operations for the year then ended and changes in net assets for each of the two
years in the period then ended, and the financial highlights for each of the
fiscal periods since 1993. These financial statements and financial highlights
are the responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of investments owned as of
September 30, 1997, by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
  In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the above mentioned Funds of Kemper National Tax-Free Income Series at
September 30, 1997, the results of their operations, the changes in their net
assets and the financial highlights for each of the fiscal periods referred to
above, in conformity with generally accepted accounting principles.

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

1    DESCRIPTION OF THE      The Kemper National Tax-Free Income Series (the
     FUND                    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             INVESTMENT VALUATION. Investments are stated at
     ACCOUNTING POLICIES     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. 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
                             basis.
 
                             EXPENSES. Expenses arising in connection with a
                             specific Fund are allocated to that Fund. Other
                             Trust expenses are allocated between the Funds in
                             proportion to their relative net assets.
 
                             FUND SHARE VALUATION. Fund shares are sold and
                             redeemed on a continuous basis at net asset value
                             (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 3:00 p.m. Chicago
                             time or the close of the Exchange. The net asset
                             value per share is determined separately for each
                             class by dividing the Fund's net assets
                             attributable to that class by the number of shares
                             of the class outstanding.
 
                                                                              29

                             FEDERAL INCOME TAXES. Each Fund has complied with
                             the special provisions of the Internal Revenue Code
                             available to investment companies and therefore no
                             federal income tax provision is required.
 
                             DIVIDENDS TO SHAREHOLDERS. Each Fund declares and
                             records a daily dividend equal to its net
                             investment income for that day, to holders of
                             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 from generally accepted
                             accounting principles.

6    FINANCIAL FUTURES
     CONTRACTS               The Municipal Fund has entered into exchange traded
                             financial futures contracts on U.S. Treasury
                             securities in order to help protect itself from
                             anticipated market conditions and, as such, bears
                             the risk that arises from entering into these
                             contracts.
 
                             At the time the 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 September
                             30, 1997, the market value of assets pledged by the
                             Fund to cover margin requirements for open futures
                             positions was $12,106,000. The fund also had liquid
                             securities in its portfolio in excess of the face
                             amount of the following short futures position open
                             at September 30, 1997:

NOTES FOR INTERMEDIATE MUNICIPAL FUND:

ZKI agreed to waive the management fee of the Intermediate Municipal Fund from
its inception, November 1, 1994, through April 30, 1995. Thereafter, the
management fee was gradually reinstated through April 30, 1996. "Other ratios to
average net assets" are computed without the undertaking to waive the management
fee.
 
Total return does not reflect the effect of any sales charges.
 
FEDERAL TAX STATUS OF 1997 DIVIDENDS FOR BOTH FUNDS

All of the dividends paid from net investment income by the Funds constitute
tax-exempt interest that is not taxable for federal income tax purpose however,
a portion of the dividends paid may be includable in the alternative minimum tax
calculation. A short-term capital gain dividend is taxable as ordinary income,
and a long-term capital gain dividend is taxable as a long-term capital gain
regardless of how long you have owned your shares.
