LETTER FROM THE CHAIRMAN
Dear Shareholders:
[Photo of A. Keith Brodkin]
As we enter the last quarter of 1996, the U.S. economy appears to have settled
into a pattern of moderate growth and inflation -- two factors that we think
can be important contributors to a favorable long-term investment climate.
During the first quarter of 1996, real (inflation-adjusted) economic growth
was 2.3% on an annualized basis, followed by a rate of 4.7% in the second
quarter. Real growth in gross domestic product has surpassed our expectations
this year, and we now expect that growth for all of 1996 could exceed 2.5%.
Although the individual consumer appears to be carrying an excessive debt
load, the consumer sector itself, which represents two-thirds of the economy,
continues to be impressive in its support of the automobile and housing
markets. Consumer spending has also been positively impacted by widespread job
growth and, more recently, increasing wages. However, the latest statistics
appear to show signs of slow consumer spending, especially in overall retail
sales, which have been flat for several months. Furthermore, the economies of
Europe and Japan continue to be in the doldrums, weakening U.S. export markets
while subduing the capital spending plans of American corporations. While
economic growth should continue, we expect it could slacken toward the end of
the year.
In the bond markets, persistent signs of economic weakness led to decreases
in short-term interest rates by the Federal Reserve Board in late 1995 and
early 1996. Should signs of more rapid economic growth and, particularly, of
higher inflation resurface, we would expect the Fed to maintain its anti-
inflationary stance. In the beginning of the year, the bond markets traded in
a narrow range as investors shifted between concern for the lack of a budget
resolution in Washington and hope that sluggish economic reports and low
inflation might lead to lower interest rates. Later, fixed-income markets
began reacting to conflicting signals regarding the economy's strength with
more volatile trading patterns marked by an upward bias in interest rates.
Interest rates may move even higher over the coming months, but we believe the
current rise in bond yields is reaching a point where fixed-income markets are
equitably valued.
Finally, you may notice, this report to shareholders incorporates a number
of changes which we hope you will find informative and useful. Following the
Fund Manager's Overview, we have added additional information on the Fund.
Near the back of the report, telephone numbers and addresses are also listed
if you would like to contact MFS.
We appreciate your support and welcome any questions or comments you may
have.

FUND MANAGER'S OVERVIEW
Dear Shareholders:
[Photo of Geoffrey L. Schechter]
The six months ended September 30, 1996 marked a period of significant
volatility in the fixed-income markets. Yields on 30-year U.S. Treasury bonds
ranged from a low of 6.60% to a high of 7.19% before settling at 6.92% on
September 30, which represented an increase of approximately 30 basis points
(0.30%) from the beginning of the period. The increase in rates experienced
during this period was primarily a result of concerns that greater-than-
expected job growth and other strong economic data would translate into higher
inflation rates.
Municipal bonds experienced the same type of volatility during this period.
The yield on long-term, high-grade municipals fluctuated between a low of
5.45% and a high of 6.00% before settling at 5.55% on September 30, which
represented a decline of about 15 basis points (0.15%) from the beginning of
the period. In this environment, Class A shares of the Fund provided a total
return of 2.55%, Class B shares 2.12%, and Class C shares 2.16%. These returns
assume the reinvestment of distributions but exclude the effects of any sales
charges. They compare to a 3.07% return for the Lehman Brothers Municipal Bond
Index (the Lehman Index), an unmanaged index of national municipal bond
investments rated "Baa" or higher, and a 2.79% average return for the tax-
exempt municipal bond fund category as reported by Lipper Analytical Services,
an independent firm that reports mutual fund performance.
Perhaps the most important aspect of the municipal market during the past
six months has been its dramatically favorable performance compared to the
U.S. Treasury market. The yield ratio of 30-year municipals rated "AAA" by
Standard & Poor's to comparable-maturity Treasuries has declined from 86% to
80%. (Note that the principal value and interest on Treasury securities are
guaranteed by the U.S. government if held to maturity.) These trends are
attributable to the municipal market's favorable technical position. New-issue
supply remains moderate as state and local governments continue to be
conservative relative to new spending and borrowing. At the same time, the
surge in redeemed bonds has led to a decrease in outstanding tradable supply.
On the demand side, property and casualty insurance companies have been strong
buyers and retail interest has remained consistent. Further aiding the decline
in yield ratios has been the apparent collapse of support for extreme tax
reform proposals.
The overall strength of municipal credits has also contributed to the
market's good relative performance. The fiscal condition of state and local
governments is the strongest it has been in several years, owing to a healthy
economy and generally sound fiscal practices. Most revenue bond issuers have
also posted favorable results. These trends, along with the continued dramatic
proliferation of bond insurance, have resulted in continued historically
narrow yield spreads in the market. Attractive values and unusual
opportunities in the investment-grade segment of the municipal market have
therefore diminished.
During the past six months, we have generally kept portfolio durations short
relative to the Lehman Index, primarily by hedging with Treasury futures
contracts. This enhanced the relative performance of the Fund given the
increase in Treasury yields. We expect to maintain this position in the
foreseeable future. We have also been working to improve the Fund's dividends
by purchasing bonds with higher book yields, or yields comparable to those at
the time they were issued, and bonds with better call protection, that is,
those not imminently eligible to be called by the issuer. Finally, in light of
very narrow yield spreads, we have tried to improve credit quality when
possible. We feel these strategies will enhance the Fund's performance
potential and earnings sustainability.
We are pleased to report that we recently made some key additions to our
staff of municipal credit analysts, and we believe the group is now one of the
strongest in the industry. The depth and experience of this staff will be
invaluable to us as we examine important credit developments such as: the new
welfare reform bill's effect on specific municipal credits; the fiscal
ramifications of future efforts to balance the federal budget; the
increasingly competitive environment facing electric utilities as a result of
deregulation trends; and the effect of continuing cost pressures on the
changing health care industry.
Respectfully,

FUND FACTS
STRATEGY: THE FUND'S INVESTMENT OBJECTIVE IS TO PROVIDE AS HIGH
A LEVEL OF CURRENT INCOME EXEMPT FROM FEDERAL INCOME
TAXES AS IS CONSIDERED CONSISTENT WITH PRUDENT
INVESTING AND PROTECTION OF SHAREHOLDER'S CAPITAL.
COMMENCEMENT OF
INVESTMENT OPERATIONS: DECEMBER 29, 1986
SIZE: $418.9 MILLION NET ASSETS AS OF SEPTEMBER 30, 1996
PERFORMANCE SUMMARY
Because mutual funds like MFS Municipal Income Fund are designed for investors
with long-term goals, we have provided cumulative results as well as the
average annual total returns for Class A, Class B, and Class C shares for the
applicable time periods.
AVERAGE ANNUAL AND CUMULATIVE TOTAL RATES OF RETURN
CLASS A INVESTMENT RESULTS
(net asset value change including reinvested distributions)
6 Months 1 Year 5 Years Life
- -------------------------------------------------------------------------------
Cumulative Total Return +2.55% +5.23% +37.01% +81.70%

Average Annual Total Return -- +5.23% + 6.50% + 6.31%
- -------------------------------------------------------------------------------
SEC Results -2.32% +0.25% + 5.46% + 5.78%
- -------------------------------------------------------------------------------
CLASS B INVESTMENT RESULTS
(net asset value change including reinvested distributions)
6 Months 1 Year 5 Years Life
- -------------------------------------------------------------------------------
Cumulative Total Return +2.12% +4.36% +33.13% +76.60%
- -------------------------------------------------------------------------------
Average Annual Total Return -- +4.36% + 5.89% + 6.00%
- -------------------------------------------------------------------------------
SEC Results -1.86% +0.39% + 5.57% + 6.00%
- -------------------------------------------------------------------------------
CLASS C INVESTMENT RESULTS
(net asset value change including reinvested distributions)
6 Months 1 Year 5 Years Life
- -------------------------------------------------------------------------------
Cumulative Total Return +2.16% +4.31% +33.26% +76.76%
- -------------------------------------------------------------------------------
Average Annual Total Return -- +4.31% + 5.91% + 6.01%
- -------------------------------------------------------------------------------
SEC Results +1.16% +3.32% + 5.91% + 6.01%
- -------------------------------------------------------------------------------
All results represent past performance and are not an indication of future
results. Investment return and principal value will fluctuate, and shares,
when redeemed, may be worth more or less than their original cost.
Class A SEC results include the maximum 4.75% sales charge. Class B SEC
results reflect the applicable contingent deferred sales charge (CDSC) which
declines over six years as follows: 4%, 4%, 3%, 3%, 2%, 1%, 0%. Class C shares
have no initial sales charge, but along with Class B shares, have higher
annual fees and expenses than Class A shares. As of April 1, 1996, Class C
shares redeemed within 12 months of purchase will be subject to a 1% CDSC. See
the prospectus for details.
Class A and Class C share performance includes the performance of the Fund's
Class B shares for periods prior to the commencement of offering of Class A
shares on September 7, 1993 and of Class C shares on January 3, 1994. Sales
charges and operating expenses for Class A, Class B, and Class C shares
differ. The Class B share performance, which is included within the Class A
share SEC performance has been adjusted to reflect the initial sales charge
generally applicable to Class A shares rather than the CDSC generally
applicable to Class B shares. The Class B share performance included within
the Class C share SEC performance, has been adjusted to reflect the lower CDSC
generally applicable to Class C shares, rather than the higher CDSC generally
applicable to Class B shares. Class A and Class C share performance has not
been adjusted, however, to reflect differences in operating expenses (e.g.,
Rule 12b-1 fees), which generally are higher for Class B shares, and not
significantly different for Class C shares.

NOTES TO FINANCIAL STATEMENTS (Unaudited)
(1) Business and Organization
MFS Municipal Income Fund (the Fund) is a diversified series of MFS Municipal
Series Trust (the Trust). The Trust is organized as a Massachusetts business
trust and is registered under the Investment Company Act of 1940, as amended,
as an open-end management investment company.
(2) Significant Accounting Policies
General - 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;
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.
Investment Valuations - Debt securities (other than short-term obligations
which mature in 60 days or less), including listed issues, are valued on the
basis of valuations furnished by dealers or by a pricing service with
consideration to factors such as institutional-size trading in similar groups
of securities, yield, quality, coupon rate, maturity, type of issue, trading
characteristics and other market data, without exclusive reliance upon
exchange or over-the-counter prices. Short-term obligations, which mature in
60 days or less, are valued at amortized cost, which approximates market
value. Futures contracts, options and options on futures contracts listed on
commodities exchanges are valued at closing settlement prices. Over-the-
counter options are valued by brokers through the use of a pricing model which
takes into account closing bond valuations, implied volatility, and short-term
repurchase rates. Securities for which there are no such quotations or
valuations are valued at fair value as determined in good faith by or at the
direction of the Trustees.
Futures Contracts - The Fund may enter into futures contracts for the delayed
delivery of securities or contracts based on financial indices at a fixed
price on a future date. In entering such contracts, the Fund is required to
deposit either in cash or securities an amount equal to a certain percentage
of the contract amount. Subsequent payments are made or received by the Fund
each day, depending on the daily fluctuations in the value of the underlying
security, and are recorded for financial statement purposes as unrealized
gains or losses by the Fund. The Fund's investment in futures contracts is
designed to hedge against anticipated future changes in interest rates or
securities prices. Investments in interest rate futures for purposes other
than hedging may be made to modify the duration of the portfolio without
incurring the additional transaction costs involved in buying and selling the
underlying securities. Investments in interest rate futures for purposes other
than hedging may be made when a Fund has cash on hand and wishes to
participate in anticipated market appreciation while the cash is being
invested. Should interest rates or securities prices move unexpectedly, the
Fund may not achieve the anticipated benefits of the futures contracts and may
realize a loss.
Investment Transactions and Income - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All premium
and original issue discount are amortized or accreted for financial statement
and tax reporting purposes as required by federal income tax regulations.
Interest payments received in additional securities are recorded on the ex-
interest date in an amount equal to the value of the security on such date.
The Fund uses the effective interest method for reporting interest income on
payment-in-kind (PIK) bonds, whereby interest income on PIK bonds is recorded
ratably by the Fund at a constant yield to maturity. Legal fees and other
related expenses incurred to preserve and protect the value of a security owed
are added to the cost of the security; other legal fees are expensed. Capital
infusions, which are generally non-recurring, incurred to protect or enhance
the value of high-yield debt securities, are reported as an addition to the
cost basis of the security. Costs that are incurred to negotiate the terms or
conditions of capital infusions or that are expected to result in a plan of
reorganization are reported as realized losses. Ongoing costs incurred to
protect or enhance an investment, or costs incurred to pursue other claims or
legal actions, are reported as operating expenses.
Fees Paid Indirectly - The Fund's custodian bank calculates its fee based on
the Fund's average daily net assets. The fee is reduced according to a fee
arrangement, which provides for custody fees to be reduced based on a formula
developed to measure the value of cash deposited with the custodian by the
Fund. This amount is shown as a reduction of expenses on the Statement of
Operations.
Tax Matters and Distributions - The Fund's policy is to comply with the
provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its net income,
including any net realized gain on investments. Accordingly, no provision for
federal income or excise tax is provided. The Fund files a tax return annually
using tax accounting methods required under provisions of the Code which may
differ from generally accepted accounting principles, the basis on which these
financial statements are prepared. Accordingly, the amount of net investment
income and net realized gain reported on these financial statements may differ
from that reported on the Fund's tax return and, consequently, the character
of distributions to shareholders reported in the financial highlights may
differ from that reported to shareholders on Form 1099-DIV.
Distributions paid by the Fund from net interest received on tax-exempt
municipal bonds are not includable by shareholders as gross income for federal
income tax purposes because the Fund intends to meet certain requirements of
the Code applicable to regulated investment companies, which will enable the
Fund to pay exempt-interest dividends. The portion of such interest, if any,
earned on private activity bonds issued after August 7, 1986 may be considered
a tax-preference item to shareholders. Distributions to shareholders are
recorded on the ex-dividend date.
The Fund distinguishes between distributions on a tax basis and a financial
reporting basis and requires that only distributions in excess of tax basis
earnings and profits are reported in the financial statements as a tax return
of capital. Differences in the recognition or classification of income between
the financial statements and tax earnings and profits which result in
temporary over-distributions for financial statement purposes, are classified
as distributions in excess of net investment income or accumulated net
realized gains.
At March 31, 1996, the Fund, for federal income tax purposes, had capital loss
carryforward of $10,162,094, which may be applied against any net taxable
realized gains of each succeeding year until the earlier of their utilization
or expiration on March 31, 2002 ($1,415,952), March 31, 2003 ($6,517,530), and
March 31, 2004 ($2,228,612).
Multiple Classes of Shares of Beneficial Interest - The Fund offers Class A,
Class B, and Class C shares. The three classes of shares differ in their
respective shareholder servicing agent, and distribution and service fees. All
shareholders bear the common expenses of the Fund pro rata based on settled
shares outstanding, without distinction between share classes. Dividends are
declared separately for each class. No class has preferential dividend rights;
differences in per share dividend rates are generally due to differences in
separate class expenses.
(3) Transactions with Affiliates
Investment Adviser - The Fund has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
advisory and administrative services, and general office facilities. The
management fee is computed daily and paid monthly at an effective annual rate
of 0.30% of the Fund's average daily net assets and 6.43% of its gross income
for its then-current fiscal year.
The Fund pays no compensation directly to its Trustees who are officers of the
investment adviser, or to officers of the Fund, all of whom receive
remuneration for their services to the Fund from MFS. Certain officers and
Trustees of the Fund are officers or directors of MFS, MFS Fund Distributors,
Inc. (MFD), and MFS Service Center, Inc. (MFSC). The Fund has an unfunded
defined benefit plan for all its independent Trustees and Mr. Bailey. Included
in Trustees' compensation is a net periodic pension expense of $5,761 for the
period ended September 30, 1996.
Distributor - MFD, a wholly owned subsidiary of MFS, as distributor, received
$11,994 as its portion of the sales charge on sales of Class A shares for the
period ended September 30, 1996.
The Trustees have adopted separate distribution plans for Class A, Class B,
and Class C shares pursuant to Rule 12b-1 of the Investment Company Act of
1940 as follows:
The Class A distribution plan provides that the Fund will pay MFD up to 0.35%
per annum of its average daily net assets attributable to Class A shares in
order that MFD may pay expenses on behalf of the Fund related to the
distribution and servicing of its shares. These expenses include a service fee
to each securities dealer who enters into a sales agreement with MFD of up to
0.25% per annum of the Fund's average daily net assets attributable to Class A
shares which are attributable to that securities dealer, a distribution fee to
MFD of up to 0.10% per annum of the Fund's average daily net assets
attributable to Class A shares, commissions to dealers and payments to MFD
wholesalers for sales at or above a certain dollar level, and other such
distribution-related expenses that are approved by the Fund. MFD retains the
service fee for accounts not attributable to a securities dealer, which
amounted to $36,570 for the period ended September 30, 1996. Payment of the
0.10% per annum Class A distribution fee will commence on such date as the
Trustees of the Trust may determine. Fees incurred under the distribution plan
during the period ended September 30, 1996 were 0.25%, of the Fund's average
daily net assets attributable to Class A shares on an annualized basis.
The Class B and Class C distribution plans provide that the Fund will pay MFD
a distribution fee of 0.75% per annum, and a service fee of up to 0.25% per
annum, of the Fund's average daily net assets attributable to Class B and
Class C shares. MFD will pay to securities dealers who enter into a sales
agreement with MFD all or a portion of the service fee attributable to Class B
and Class C shares, and will pay to such securities dealers all of the
distribution fee attributable to Class C shares. The service fee is intended
to be additional consideration for services rendered by the dealer with
respect to Class B and Class C shares. MFD retains the service fee for
accounts not attributable to a securities dealer, which amounted to $47,910
and $4,993 for Class B and Class C shares, respectively, for the period ended
September 30, 1996. Fees incurred under the distribution plans during the
period ended September 30, 1996 were 1.00% of the Fund's average daily net
assets attributable to Class B and Class C shares on an annualized basis.
Purchases over $1 million of Class A shares are subject to a contingent
deferred sales charge in the event of a shareholder redemption within 12
months following such purchase. A contingent deferred sales charge is imposed
on shareholder redemptions of Class B shares in the event of a shareholder
redemption within six years of purchase. A contingent deferred sales charge is
imposed on shareholder redemptions of Class C shares in the event of a
shareholder redemption within 12 months of purchases made on or after April 1,
1996. MFD receives all contingent deferred sales charges. Contingent deferred
sales charges imposed during the period ended September 30, 1996 were $0,
$308,629, and $495 for Class A, Class B, and Class C shares, respectively.
Shareholder Servicing Agent - MFSC, a wholly owned subsidiary of MFS, earns a
fee for its services as shareholder servicing agent. The fee is calculated as
a percentage of the average daily net assets of each class of shares at an
effective annual rate of up to 0.15%, up to 0.22%, and up to 0.15%
attributable to Class A, Class B, and Class C shares, respectively.
(4) Portfolio Securities
Purchases and sales of investments, other than U.S. government securities,
purchased option transactions and short-term obligations, aggregated
$59,118,752 and $79,880,594, respectively.
The cost and unrealized appreciation or depreciation in value of the
investments owned by the Funds, as computed on a federal income tax basis, are
as follows (000 omitted):
Aggregate cost $387,240,942
============
Gross unrealized appreciation $ 32,398,597
Gross unrealized depreciation (2,595,528)

(6) Line of Credit
The Fund entered into an agreement which enables it to participate with other
funds managed by MFS in an unsecured line of credit with a bank which permits
borrowings up to $350 million, collectively. Borrowings may be made to
temporarily finance the repurchase of Fund shares. Interest is charged to each
fund, based on its borrowings, at a rate equal to the bank's base rate. In
addition, a commitment fee, based on the average daily unused portion of the
line of credit, is allocated among the participating funds at the end of each
quarter. The commitment fee allocated to the Fund for the period ended
September 30, 1996 was $2,115.
(7) Financial Instruments
The Fund trades financial instruments with off-balance sheet risk in the
normal course of its investing activities in order to manage exposure to
market risks such as interest rates. These financial instruments include
futures contracts. The notional or contractual amounts of these instruments
represent the investment the Fund has in particular classes of financial
instruments and does not necessarily represent the amounts potentially subject
to risk. The measurement of the risks associated with these instruments is
meaningful only when all related and offsetting transactions are considered.
The following is a summary of such securities held at September 30, 1996:

At September 30, 1996, the Fund had sufficient cash and/or securities to cover
margin requirements on open futures contracts.
The Fund also invests in indexed securities whose value may be linked to
interest rates, commodities, indices or other financial indicators. Indexed
securities are fixed-income securities whose proceeds at maturity (principal-
indexed securities) or interest rates (coupon-indexed securities) rise and
fall according to the change in one or more specified underlying instruments.
Indexed securities may be more volatile than the underlying instrument itself.

The Fund may invest not more than 15% of its net assets in securities which
are subject to legal or contractual restrictions on resale. At September 30,
1996, the Fund owned the following restricted security (constituting 0.15% of
net assets) which may not be publicly sold without registration under the
Securities Act of 1933. The Fund does not have the right to demand that such
