+ Current annualized distribution rate is the latest monthly dividend shown as
  an annualized percentage of net asset value on February 28, 1997.
  Distribution rate simply measures the level of dividends and is not a
  complete measure of performance. The SEC yield is net investment income per
  share earned over the month ended February 28, 1997 shown as an annualized
  percentage of the maximum offering price on that date. The SEC yield is
  computed in accordance with the standardized method prescribed by the
  Securities and Exchange Commission. Tax equivalent yield is based on the
  fund's yield and the applicable 1996 federal and state marginal tax rate.
  Income may be subject to state and local taxes and, for some investors, a
  portion may be subject to the alternative minimum tax.

ECONOMIC OVERVIEW

DEAR SHAREHOLDER:
 
The Federal Reserve Board's recent decision to raise short-term interest rates
as a pre-emptive strike against inflation has changed the course that the
markets have been on for several months. In fact, we had not seen a change in
the federal funds target rate since January 1996, when the Fed reduced interest
rates. The raising of rates now -- coupled with the general expectation of at
least one and probably two more hikes -- requires a modest adjustment in our
views for 1997.

  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, alternately strong and
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. However, the Fed has
become nervous about the recent modest increases in unit labor costs. To avert
the possibility of more severe later actions to control inflation, the Fed
decided to act now. Ironically, now that rates have been raised, we may never
know whether the economy was in fact in danger of overheating.

  Investors' immediate reaction to the higher rates was negative, as evidenced
by the stock market's first sizable correction in years. Yet, as uncomfortable
as it is to participate in a market decline, a correction is a natural event in
a market cycle. A market correction is generally defined as a loss in value of 8
to 10 percent. Historically, corrections take place over a period of four to six
months, the current one has already fallen the average amount in a very short
amount of time. It is likely that the stock market will require many weeks of
retrenchment before a new sustainable upward movement begins.

  A correction should be distinguished from a bear market, which involves a
decline of at least 20 percent and typically occurs over six to eight months. We
see no reason to believe that we are entering a classic bear market. The economy
is stable and the interest rate increases are likely to be gradual and modest.
Inflation is the greatest threat to the securities markets, and if higher rates
are what is required to control inflation, investors will be better off over the
longer term.

  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 all-time high early in 1997 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.

  One of the most interesting aspects of today's environment is the role of the
technology stocks. They seem to be demonstrating the same market leadership
characteristics that we have seen before. In the early 1970s, consumer
nondurable stocks led the market up and down. More recently, in the 1980s, oil
stocks led, followed by financial services stocks. Today, we look at technology
stocks as a strong indicator of market direction. When they finally find a
bottom and then turn upward, we would expect the general market to follow.

  Higher interest rates are, of course, anathema to the fixed-income market. The
market has fallen, discounting a more restricting monetary policy. However, in
the era of instant adjustment, most of the damage is likely done. We expect now
that the bond market is likely to trade in a very narrow range -- with long-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.

Economic activity is a key influence on investment performance and sharholder
decision-making.  Periods of recession or boom, inflation or deflation, credit
expansion or credit crunch has 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.

(1) Falling interest rates in recent years have been a big plus for financial
    assets.

(2) The interest rate that commercial lenders charge their best borrowers.

(3) Inflation reduces an investor's real return.  In the last five years,
    inflation has been as high as 6%.  The low, moderate inflation of the last
    few years has meant hight real returns.

(4) Changes in the exchange value of the dollar impact U.S. exporters and
    the value of U.S. firms' foreign profits.

(5) These influence corporate profits and equity performance.

(6) An influence on family income and retail sales.

        A natural response to a troubled U.S. equity market is to look abroad. 
In fact, the valuations of many international markets are more attractive than
the U.S.  There too, though, weak German and Japanese economies make it
difficult to identify exciting near-term opportunities.

        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 that 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 THE KEMPER STATE TAX-FREE INCOME SERIES. MIER
RECEIVED B.A. DEGREE IN ECONOMICS FROM THE UNIVERSITY OF MICHIGAN AND WENT ON TO
RECEIVE A 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.

FOR THE SIX-MONTH REPORTING PERIOD, THE MUNICIPAL MARKET FOCUSED PRIMARILY ON
THE POTENTIAL OF AN INTEREST RATE INCREASE BY THE FEDERAL RESERVE BOARD.
PORTFOLIO MANAGER CHRIS MIER EXPLAINS HOW THE FUNDS IN KEMPER STATE TAX-FREE
INCOME SERIES PERFORMED IN AN ENVIRONMENT CHARACTERIZED BY QUICK CHANGING 
EXPECTATIONS.
 
Q    HOW DID THE FUNDS PERFORM DURING THE FIRST SIX MONTHS OF THE FISCAL YEAR?
 
A    The funds (Class A shares, unadjusted for sales charge) performed
relatively well, all returning 4 percent or more for the six-month period ended
February 28, 1997. Most of the return reflected income from the bonds in the
portfolios with some level of price appreciation.
 
Q    MUNICIPAL BOND YIELDS FLUCTUATED QUITE A BIT DURING THE LAST SIX MONTHS.
WHAT IMPACT DID THIS HAVE ON THE MARKET?
 
A    Yields in the municipal market fluctuated during the period, but tended to
be range-bound, trading within about a half of a percentage point. 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 up and down movement of yields seemed to be 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 reporting period on the heels of sometimes conflicting economic
reports. The Fed took no action during the six-month period and the municipal
bond market performed relatively well, slightly outperforming the Treasury bond
market.
 
Q    WHAT TYPES OF ADJUSTMENTS DID YOU MAKE TO THE FUNDS OVER THE SIX MONTHS?
 
A    We shortened the durations of the funds somewhat during the period. The
shorter a fund's duration, the less sensitive it is to interest rate changes. We
shortened duration because we believed that growth in the economy would exceed
market expectations. We also saw signs of potential wage inflation and combined
with our outlook on economic growth, saw a bias for higher market interest
rates.
 
  In addition to duration adjustments, we also 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 didn't make any significant shifts in the sectors in which the funds were
invested. However, we continued to favor essential service revenue bonds --
bonds used to finance basic governmental services such as water and sewer,
transportation and education among other things.

Q    WERE THERE ANY SIGNIFICANT TRENDS THAT AFFECTED INDIVIDUAL STATES WITHIN
KEMPER'S STATE TAX-FREE INCOME SERIES?
 
A    The California economy continued to improve during the period. Unemployment
in the state decreased by about 1 percent from 1995, and the state's general
fund was increased due to stronger tax receipts from California's economic
recovery. New municipal issuance supply also increased during the period.
 
  In Texas, the Gross State Product grew by more than $12.8 billion in 1996 -- a
3 percent increase over 1995. Unemployment continued to decline and the state is
expected to outpace the national economy in 1997, due to continued economic
growth trends in Texas. New issuance volume in the state has also increased.
 
  Unemployment continued to fall in Michigan during the period and is below the
national average. Michigan ranks in the top 15 states nationwide on key measures
of wealth, such as median family and disposable personal income. In 1996, new
municipal issuance volume was $5.6 billion, a 15 percent increase from 1995.
 
  Economic growth in Ohio continues to be positive and the state's general fund
has maintained a surplus. There was a 30 percent increase in new issuance volume
in Ohio in 1996 compared to 1995 levels.
 
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'S YOUR OUTLOOK FOR THE MUNICIPAL MARKET?
 
A    We expect moderate growth in the economy to continue, with a bias for a
slight pick-up in inflation and possibly an increase in short-term interest
rates. Municipal supply should come in close to 1996 levels.

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 reports on the
municipal bond market.
 
TOTAL RETURN A fund's total return figure measures both the net investment
income generated by, and the effect of, 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
     FUND                    Kemper California Tax-Free Income Fund, Kemper
                             Michigan Tax-Free Income Fund, Kemper Ohio Tax-Free
                             Income Fund and Kemper Texas Tax-Free Income Fund
                             (collectively the Funds) are four of eight
                             investment portfolios comprising the Kemper State
                             Tax-Free Income Series (the Trust). The remaining
                             portfolios are Kemper Florida, Kemper New Jersey,
                             Kemper New York and Kemper Pennsylvania Tax-Free
                             Income Funds. The Trust is an open-end management
                             investment company organized as a business trust
                             under the laws of Massachusetts.
 
                             Each Fund offers three 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. 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
                             basis.
 
                             EXPENSES. Expenses arising in connection with a
                             specific Fund are allocated to that Fund. Other
                             Trust expenses are allocated among 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.
 
                             FEDERAL INCOME TAXES. Each Fund has complied with
                             the special provisions of the Internal Revenue Code
                             available to investment companies for the six
                             months ended February 28, 1997.
 
                             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 than generally accepted
                             accounting principles.

6    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 February 28, 1997,
                             the market values of assets pledged by the Funds to
                             cover margin requirements for open futures
                             positions were $6,054,000, $14,000, $416,000 and
                             $117,000 for the California, Michigan, Ohio and
                             Texas Funds, respectively. The Funds also had
                             liquid securities in their portfolios in excess of
                             the face amount of the following short Treasury
                             Bond futures open at February 28, 1997:
