MFS[RegTM] Municipal Income Trust

Semiannual Report
April 30, 1997

[End Graphic]

<PAGE>


Dear Shareholders:
For the six months ended April 30, 1997, shares of the Trust provided a total
return of 3.78% based on its New York Stock Exchange price. Over the same period
the Lehman Brothers Municipal Bond Index, an unmanaged index of investment-
grade, fixed-rate municipal bonds, provided a total return of 2.01%, and the
Lehman Brothers High Yield Municipal Bond Index, an unmanaged index of
fixed-rate, below-investment-grade municipal bonds, provided a total return of
1.86%. The net asset value of the Trust declined from $8.58 to $8.31 over the
period, providing a total return of 0.51%. The Trust's return assumes the
reinvestment of distributions. Additionally, the Trust primarily invests in
lower-quality municipal issues rated "Baa" or below or those that are unrated.
These lower-rated securities have high coupon rates relative to the market and
generally are less price sensitive in a volatile interest-rate environment;
hence, they provide less price fluctuation during these periods (although
investments in high-yield securities involve greater degrees of credit and
market risk than investments in higher-rated securities and tend to be more
sensitive to economic conditions).

Economic Environment
After more than six years of expansion, the U.S. economy is experiencing another
year of growth in 1997, although a few signs point to the possibility of a
modest rise in inflation during the year. On the positive side, the pattern of
moderate growth and inflation set over the past few years now seems fairly well
entrenched in the economy and, short of a major international or domestic
crisis, appears to have enough momentum to remain on track for some time. Also,
gains in such important sectors as housing, automobiles, industrial production,
and exports indicate a fair amount of underlying strength in the economy. Some
of that strength was seen in the first quarter, when the U.S. economy grew at an
annualized rate of 5.6% (based on preliminary estimates), a pace that would be
inflationary in the unlikely event that it were to continue. The ongoing
tightness in the labor market could also add some inflationary pressures to the
economy. At the same time, there is some reason for caution as a result of the
continuing high level of consumer debt and rising personal bankruptcies. Given
these somewhat conflicting indicators, we expect real (inflation-adjusted)
growth to revolve around 2% in 1997, with the strength of the first quarter
moderating as we move through the balance of the year.

Bond Markets
In the bond markets, conflicting signals over the strength of the economy have
also created near-term volatility, and the Federal Reserve Board has begun
taking measured steps to control inflation by raising short-term interest rates.
Although we do not expect a repeat of the rapid growth in the first quarter, we
would expect the Fed to raise interest rates at least one more time in reaction
to the economic momentum that was built up during the period. While inflationary
forces largely remained in check in 1996, the continued strength in the labor
market suggests that a pickup in inflation is still possible. At the same time,
the U.S. budget deficit continues to decline and, as a percentage of gross
domestic product, is now approaching 1%, which we consider a positive
development for the bond markets. Although interest rates may remain volatile
over the coming months, we believe that, at current levels, fixed-income markets
remain equitably valued.

Portfolio Performance and Strategy
After the 1996 election, investors rebuffed any further rumors of a flat tax and
once again began to support the municipal market through investments in mutual
funds as well as individual municipal bonds. The credit problems that plagued
the market in the past in places such as Orange County, California and Miami,
Florida were resolved and faded from the front pages of the newspapers. Revenue
growth on both the state and local levels, combined with strong fiscal
management, also renewed investor confidence in the municipal market.

Because of investor worries about inflation, higher-yielding, higher-coupon
bonds have been in great demand, thereby causing spread, or yield differentials,
to narrow relative to investment-grade bonds.


                                                                               1
<PAGE>

We will continue to watch this spread relationship and avoid situations in which
we do not believe we are being adequately compensated for any added risk
resulting from the narrowing spreads. Our corporate-backed bonds in the airline
industry have done very well due to strong earnings and increased passenger
load, while many other corporate-backed issues have provided strong debt-service
coverage and increased value due to the economic expansion. However, we feel we
are late in the expansion cycle and that profits for many corporations have
peaked. We will closely monitor these holdings for signs of weakness in the
months ahead. Single-family mortgage-revenue bonds have held up very well
against the bond markets' volatility. Because of the zigzagging of interest
rates, mortgage prepayments have been low, keeping the risk of calls, or early
redemptions, down as well.

The Trust's portfolio structure is consistent with its investment objective of
providing a high level of current tax-exempt income through generally
lower-rated or unrated securities. The Trust's monthly distribution of $0.055
per share has remained stable for the past six months. Increased bond call
activity, lack of investment opportunities consistent with the Trust's
objective, and a falling interest-rate environment could put pressure on the
distribution in the months ahead.

Our efforts remain focused on research and preservation of high current
tax-exempt income. We continue to monitor our holdings closely and to seek out
new investment opportunities. Diversification of credit risk and of factors that
might affect liquidity remain important components of the Trust's overall
strategy.

We appreciate your support and welcome any questions or comments you may have.

Investment Objective and Policy

The investment objective of MFS[RegTM] Municipal Income Trust is to provide high
current income exempt from federal income taxes.

The Trust seeks to achieve its objective by investing primarily in medium-and
lower-quality municipal bonds and notes. The Trust may also enter into futures
contracts and purchase securities on a "when-issued" basis.

Number of Employees

The Trust is organized as a Massachusetts business trust and is registered under
the Investment Company Act of 1940, as amended, as a closed-end, nondiversified,
management investment company and has no employees.

New York Stock Exchange Symbol

The New York Stock Exchange symbol is MFM.

Number of Shareholders

As of April 30, 1997, our records indicate that there are 7,157 registered
shareholders and approximately 16,600 shareholders owning Trust shares in
"street" name, such as through brokers, banks, and other financial
intermediaries.

If you are a "street" name shareholder and wish to directly receive our reports,
which contain important information about the Trust, please write or call:

        State Street Bank and Trust Company
        P.O. Box 8200
        Boston, MA 02266-8200
        1-800-637-2304


Dividend Reinvestment and
Cash Purchase Plan

The Trust offers a Dividend Reinvestment and Cash Purchase Plan which allows you
to reinvest either all of the distributions or only the long-term capital gains
paid by the Trust. Unless the shares are trading at a premium (exceeding net
asset value), purchases are made at the market price. Otherwise, purchases will
be made at a discounted price of either the net asset value or 95% of the market
price, whichever is greater. You can also buy shares of the Trust. Investments
from $100 to $500 can be made in January and July on the 15th of the month or
shortly thereafter.

If your shares are in the name of a brokerage firm, bank, or other nominee, you
can ask the firm or nominee to participate in the Plan on your behalf. If the
nominee does not offer the Plan, you may wish to request that your shares be
re-registered in your own name so that you can participate.

There is no service charge to reinvest distributions, nor are there brokerage
charges for shares issued directly by the Trust. However, when shares are bought
on the New York Stock Exchange or otherwise on the open market, each participant
pays a pro rata share of the commissions. A service fee of $0.75 is charged for
each cash purchase as well as a pro rata share of the brokerage commissions, if
any. The automatic reinvestment of distributions does not relieve you of any
income tax that may be payable (or required to be withheld) on the
distributions.

To enroll in or withdraw from the Plan or to receive a brochure providing a
complete description of the Plan, please contact the Plan agent at the address
and telephone number located on the back cover of this report. Please have
available the name of the Trust and your account and Social Security numbers.
For certain types of registrations, such as corporate accounts, instructions
must be submitted in writing. When you withdraw from the Plan, you can receive
the value of the reinvested shares in one of two ways: a check for the value of
the full and fractional shares, or a certificate for the full shares and a check
for the fractional shares.


                                                                               3

Notes to Financial Statements (Unaudited)

(1) Business and Organization

MFS Municipal Income Trust (the Trust) is a non-diversified, closed-end
management company. The Trust is organized as a Massachusetts business trust and
is registered under the Investment Company Act of 1940, as amended.


(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 and
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.

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.
Dividends received in cash are recorded on the ex-dividend date. Dividend and
interest payments received in additional securities are recorded on the
ex-dividend or ex-interest date in an amount equal to the value of the security
on such date.

The Fund can invest up to 100% of its portfolio in high-yield securities rated
below investment grade. Investments in high-yield securities involve greater
degrees of credit and market risk than investments in higher-rated securities,
and tend to be more sensitive to economic conditions.

The Fund uses the effective interest method for reporting interest income on
payment-in-kind (PIK) bonds. Legal fees and other related expenses incurred to
preserve and protect the value of a security owned 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 additions 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 expensed.

Fees Paid Indirectly -- The Trust's custodian bank calculates its fee based on
the Trust'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
Trust. This amount is shown as a reduction of expenses on the Statement of
Operations.

                                                                              13

Notes to Financial Statements (Unaudited) -- continued

Tax Matters and Distributions -- The Trust'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 Trust 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 Trust'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 Trust from net interest received on tax-exempt
municipal bonds are not includable by shareholders as gross income for federal
income tax purposes because the Trust intends to meet certain requirements of
the Code applicable to regulated investment companies, which will enable the
Trust 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 Trust 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 October 31, 1996, the Trust, for federal tax purposes, had a capital loss
carryforward of $31,565,822, which may be applied against any net taxable
realized gains of each succeeding year until the earlier of its utilization or
expiration, October 31, 1999 ($1,898,227), October 31, 2000 ($4,765,334),
October 31, 2001 ($3,636,033), October 31, 2002 ($7,977,644), October 31, 2003
($4,513,979), and October 31, 2004 ($8,774,605).


(3) Transactions with Affiliates

Investment Adviser -- The Trust 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 annual rate of 0.40% of
average daily net assets and 6.32% of investment income.

The Trust pays no compensation directly to its Trustees who are officers of the
investment adviser, or to officers of the Trust, all of whom receive
remuneration for their services to the Trust from MFS. Certain officers and
Trustees of the Trust are officers or directors of MFS. The Trust has an

services agreement with MFS to provide the Trust with certain financial, legal,
compliance, shareholder communications, and other administrative services. As a
partial reimbursement for the cost of providing these services, the Trust pays
MFS an administrative fee up to 0.015% per annum of the Trust's average daily
net assets, provided that the administrative fee is not assessed on Trust assets
that exceed $3 billion.

(7) Line of Credit

The Trust 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 $400 million, collectively. Borrowings may be made to
temporarily finance the repurchase of Trust 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 Trust for the six months ended
April 30, 1997, was $1,434.


(8) Financial Instruments

The Trust also invests in indexed securities whose value may be linked to
foreign currencies, 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 following is a summary of such securities held
at April 30, 1997:

are subject to legal or contractual restrictions on resale. At April 30, 1997,
the Trust owned the following restricted securities (constituting 5.90% of total
assets) which may not be publicly sold without registration under the Securities
Act of 1933 (the 1933 Act). The Trust does not have the right to demand that
such securities be registered. The value of these securities is determined by
valuations supplied by a pricing service or brokers or, if not available, in
good faith by or at the direction of the Trustees.
