TERMS TO KNOW
 
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, assuming the
reinvestment of all dividends. It represents the aggregate percentage or dollar
value change over the period. Total return may be based upon net asset value or
market price.
 
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.

DEAR SHAREHOLDERS,
 
Stable economic growth, low interest rates and sustained low inflation continued
to produce a beneficial market environment for investors in the second quarter
of 1998. Despite heightened sensitivity to earnings estimates and announcements,
the economy continued to support financial assets. We expect this favorable
climate to continue -- in spite of the sensitivity -- at least over the shorter
term.

  As always, expectations have been at the heart of the actions and reactions
that move the markets. Expectations appear to be high, as demonstrated by a
record flow of new cash into mutual funds. As of April 30, 1998, a record $5
trillion in mutual fund assets surpassed total assets of the nation's banks,
according to the Investment Company Institute, a trade organization that
monitors the mutual fund industry, and the Federal Reserve Bank in Washington.

  Unfortunately, high expectations often combine with high anxiety -- today's
investors are attuned to even the smallest hint of economic change. The result
is volatility. Many who believe that our long-running bull market is too good to
be true or that stock prices are too high are wondering when the market will
reverse.

  While a reversal may not be on the immediate horizon, investors are wise to
watch for several signs that change is underway: rising prices, indicating
higher inflation; repercussions of the Asian economic crisis on American
business, which could appear in the form of reduced earnings; and a continued
widening of our trade deficit, a serious imbalance caused by heightened American
demand for foreign goods and services.

  But at its monetary policy meeting at the end of the second quarter, the
Federal Reserve Board (the Fed) again chose to leave interest rates alone. In
the coming months, the Fed could raise interest rates if inflation accelerates
or if growth appears to be too rapid compared to the Fed's expectations.

  Our positive outlook for the short term is based primarily on the current
resiliency of our marketplace. The United States appears to be firmly planted in
the middle of an economic cycle, with no evidence of detrimental pressures that
might be associated with the market's phenomenal growth. We are not seeing
widespread price increases for goods and services or a downturn in the housing
market, both of which we might expect late in an economic cycle.

  Equities have continued to reward investors. The U.S. stock market, as
measured by the Standard & Poor's 500, gained nearly 18 percent in the first
half of 1998 but just 3.5 percent in the second quarter as profit concerns moved
front and center. Bonds in 1998 have also rewarded investors in terms of real
return, which is total return less the rate of inflation. The Treasury and high
yield debt markets have performed particularly well.

  U.S. economic growth, as measured by the gross domestic product (GDP) growth
rate, was slightly above 5 percent for the first quarter. Our general
expectation for the year is that growth in all of 1998 will increase between 2.5
and 3 percent over last year. In other words, the economy will remain strong,
but will continue to slow down as the year progresses.

  Consumer spending and corporate fixed investment have fueled the economy's
solid growth. Spending on both capital goods and high technology has been
strong. Corporate profit growth has continued to slow, which appears to be
acceptable to investors in an environment of stable interest rates. U.S.
employment growth has ranged from 2 to 2.25 percent, continuing to exceed
expectations. Consumer confidence has remained at all-time highs. The increase
in output prices, an indicator of inflation measured by the Consumer Price Index
(CPI), has stayed at 1.5 to 2 percent.

  Adding to the good news, all seems to be quiet on the domestic policy front.
At the end of February, the U.S. federal budget deficit essentially vanished.
Recent efforts to reduce the deficit, combined with higher federal revenues due
to the robust economy, have left us with an expected budget surplus of $60
billion to $80 billion for fiscal 1998. To date, our Democratic president and
Republican Congress have not agreed on any significant legislation regarding tax
credits, spending cuts or health care that could threaten the newfound federal
budget surplus.

  Can we expect a little more excitement from overseas? A full-scale global
recession from last year's Asian economic crisis seems unlikely at this point.
Although the crisis has impacted exporters in particular, it has yet to hurt
most U.S. businesses and investors. Quite the

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.

contrary. While the mere threat of repercussions from the Asian crisis added to
the anxiety mentioned earlier, it has also had the effect of keeping U.S.
interest rates and prices in check, making the U.S. economy all the more
attractive to investors around the world.

        In the global economy, the U.S. dollar continues to appreciate in value
compared to other currencies. In fact, more capital is flowing into U.S.
markets as investors generally avoid Asia. Europe also has been benefiting from
the crisis. Canada, which is a commodity-producing exporter, has been somewhat
negatively affected as commodity prices have fallen. Political unrest in
Indonesia, nuclear tests in India and Pakistan and economic turmoil in Russia
have been keeping international investors on the edges of their seats.

        Other major developments abroad include the final selection of
countries to participate in Europe's single currency next year. Many European
countries are adopting more restrictive fiscal policy and reducing inflation in
anticipation of their momentous entry into the European Economic and Monetary
Union (EMU). But after the EMU is established in 1999, tensions may indeed
mount as countries work to adapt to the new structure.

        As we approach the turn of the century, one caveat remains: Don't
underestimate the potential of the Year 2000 computer code problem. It appears
that a significant number of federal government agencies will not meet the
criteria necessary to avoid the problem. Many businesses are revealing that
billions of dollars are being spent on the situation. Some experts say a global
recession is in store. Others adamantly disagree. In any event, we may indeed
see a reduction in capital spending toward the of 1998 and the first half of
next year as companies focus on fixing existing computers rather than on
purchasing new equipment. We'll keep you posted!
 
        Thank you for your continued support. We appreciate the opportunity to
serve your investment needs.
 
Sincerely,
 
/s/ John E. Silvia

PERFORMANCE UPDATE
 
[MIER PHOTO]

CHRISTOPHER MIER JOINED SCUDDER KEMPER INVESTMENTS, INC. IN 1986 AND IS A
MANAGING DIRECTOR. MIER IS A VICE PRESIDENT AND PORTFOLIO MANAGER OF KEMPER
MUNICIPAL INCOME TRUST. MIER RECEIVED A BACHELOR'S DEGREE IN ECONOMICS FROM THE
UNIVERSITY OF MICHIGAN AND EARNED HIS M.M. IN FINANCE FROM THE 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.
 
KEMPER MUNICIPAL INCOME TRUST EXPERIENCED STRONG PERFORMANCE DURING THE
SIX-MONTH PERIOD AGAINST A BACKDROP OF RECORD LOW INFLATION, HIGH NEW
ISSUE VOLUME AND THE ASIAN MARKETS AND CURRENCIES CRISIS. PORTFOLIO MANAGER
CHRIS MIER EXPLAINS HOW THESE FACTORS AFFECTED THE FUNDS AND MUNICIPAL MARKET
AND WHAT HE EXPECTS FOR THE REMAINDER OF THE FUND'S FISCAL YEAR.
 
Q     KEMPER MUNICIPAL INCOME TRUST PERFORMED WELL DURING THE SIX-MONTH PERIOD
ENDED MAY 31, 1998, WITH A TOTAL RETURN BASED ON NET ASSET VALUE OF 3.90 PERCENT
COMPARED TO THE LIPPER ANALYTICAL SERVICE'S GENERAL MUNICIPAL DEBT CATEGORY
AVERAGE OF 4.06 PERCENT. TO WHAT DO YOU ATTRIBUTE THIS PERFORMANCE?
 
A     We concentrated on keeping the fund fully invested in solid municipal bond
issues throughout the period, which can help explain its performance. With a
closed-end fund, we don't adjust the duration of the portfolio with the same
level of activity as we do in our open-end municipal bond fund.
 
      However, I want to add a reminder that this fund was created to deliver 
a high level of tax-exempt income and not primarily for total return, although
we give the Lipper figures for information purposes. Since the fund's creation
in 1988, it has not experienced a dividend cut or missed a monthly dividend,
something we feel investors value.
 
Q     THE DIVIDEND WAS STABLE THROUGHOUT THE PERIOD, BUT THE MARKET PRICE FELL
THREE MONTHS IN A ROW. WHY?
 
A     Market price made a big comeback in May when it gained 5.97 percent after
falling in February, March and April. We announced in February we were lowering
the dividend of Kemper Strategic Municipal Income Trust. In my view, I think the
implication of the cut for Kemper Strategic Municipal Income Trust had a
negative impact on this fund. It's also my opinion that once it was clear a cut
was not in the plans for Kemper Municipal Income Trust, the fund benefited,
resulting in the comeback in May.
 
Q     WHAT OVERALL MARKET FACTORS AFFECTED THE MUNICIPAL BOND MARKET DURING
THESE SIX MONTHS?
 
A     Strong economic growth, lower-than-expected inflation, declining interest
rates and, of course, the continuation of the Southeast Asian currency and
market crisis were the main four factors that affected the municipal bond market
from December 1, 1997 through May 31, 1998.
 
Q     YOU MENTION THE SOUTHEAST ASIAN CURRENCY AND MARKET CRISIS AS A FACTOR
AFFECTING THE BOND MARKET. COULD YOU EXPLAIN THE EFFECT THE CRISIS HAD ON THE
MARKET?
 
A     When the Hong Kong stock market followed other Asian markets and crashed
last fall, investors worldwide sought safe investment vehicles. U.S. dollar and
dollar-denominated investments, particularly those of high quality and
liquidity, such as U.S. Treasuries, experienced a massive cash inflow. This is
generally referred to as "flight to quality." The municipal bond market, which
often moves in tandem with the Treasury market, benefited from the resulting
declining interest rate environment.



                                                                               5

PERFORMANCE UPDATE
 
Q     THE AMOUNT OF NEW MUNICIPAL ISSUES CONTINUES AT A HEAVY RATE. WHAT EFFECT
DID THIS HAVE ON THE MARKET AND THE FUND'S PERFORMANCE?
 
A     The volume of new issues forced municipal rates to stay attractive
relative to their taxable counterparts. Municipal rates were about 92.5 percent
of a 30-year Treasury bond at the end of the fund's six-month period.
 
Q     DO YOU ANTICIPATE THIS HIGH VOLUME TO CONTINUE?
 
A     The elevated supply was due to two factors -- declining interest rates,
which led to an increase in advanced refunding issues, and continued growth in
new project financing. The economy has been strong with inflation not much of a
threat, so municipalities can afford to undertake large capital improvements and
other projects that municipal bonds are issued to finance. New issue volume has
been increasing year over year, and while it will have to subside at some point,
I don't see any signs of slowing yet.
 
Q     HOW HAS THE DIRECTION OF INTEREST RATES AFFECTED THE MARKET?
 
A     Throughout half of this period, the Federal Reserve Board (the Fed) had
indicated a bias toward tightening rates because of strong domestic growth. When
the economy expands too quickly, inflation becomes a threat. The Fed was poised
to slow that growth by raising interest rates. However, minutes released in
February indicated the Fed went to a neutral bias at its December meetings
because it was becoming apparent the Asian crisis would have a deflationary
effect and offset our very strong economy to some degree. When the Fed met again
in March, it again made no move to change rates.
 
Q     EL NINO AND OTHER UNUSUAL WEATHER HAVE PLAGUED MUCH OF THE U.S. WILL THE
COSTS ASSOCIATED WITH REBUILDING AFFECT A MUNICIPALITY'S ABILITY TO REPAY THEIR
OBLIGATIONS?
 
A     When a natural disaster occurs, cities, counties and states receive a
great deal of federal money and insurance money to repair whatever has been
destroyed, so a disaster isn't generally as much of a financial drain as would
be expected.
 
Q     WHAT IS YOUR OUTLOOK FOR THE MUNICIPAL BOND MARKET?
 
A     The market is likely to be relatively range bound, and prices should
remain somewhat stable. I do think rates will trend lower again once the
domestic economy begins to slow somewhat due to the effect from the Asian
problems.
 
Q     IS THIS STILL A GOOD TIME TO BE IN MUNICIPALS?
 
A     I think municipals are quite attractive right now. They're at high yield
percentages to Treasuries and offer attractive real rates of interest because of
our current low rate of inflation. If supply begins to taper off and the economy
begins to slow, that should be more good news for the fund.
 
YEAR 2000 

YEAR 2000 ISSUE
Like other registered investment companies and financial and business
organizations worldwide, the fund could be adversely affected if computer
systems on which the fund relies, which primarily include those used by the
Manager, its affiliates or other service providers, are unable to correctly
process date-related information on and after January 1, 2000. This risk is
commonly called the Year 2000 Issue. Failure to successfully address the Year
2000 Issue could result in interruptions to and other material adverse effects
on the fund's business and operations. The Manager has commenced a review of the
Year 2000 Issue as it may affect the fund and is taking steps it believes are
reasonably designed to address the Year 2000 Issue, although there can be no
assurances that these steps will be sufficient. In addition, there can be no
assurances that the Year 2000 Issue will not have an adverse effect on the
municipalities whose securities are held by the fund or on global markets or
economies generally.

                             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. 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
                             issue discount amortization on fixed income
                             securities. Realized gains and losses from
                             investment transactions are reported on an
                             identified cost basis.
 
                             FEDERAL INCOME TAXES. The Fund has complied with
                             the special provisions of the Internal Revenue Code
                             available to investment companies for the six
                             months ended May 31, 1998. The accumulated net
                             realized loss on sales of investments for federal
                             income tax purposes at May 31, 1998, amounting to
                             approximately $8,632,000, is available to offset
                             future taxable gains. If not applied, the loss
                             carryover expires during the period ending 2003.

                             determined in accordance with income tax principles
                             which may treat certain transactions differently
                             from generally accepted accounting principles.

                             $5,000 per share. The dividend rate on each series
                             is set by the remarketing agent, and the dividends
                             are paid every 28 days. Preferred shareholders will
                             vote together with common shareholders as a single
                             class and have the same voting rights, subject to
                             certain class specific preferences.
