PERFORMANCE HIGHLIGHTS



    --   The fund's class A shares have earned Morningstar's ranking of
         four stars, out of a possible five, based on risk-adjusted 3- and
         5-year performance, through September 30, 1994. The fund's class A
         shares have held a 4- or 5-star ranking since June 30, 1992.*

    --   Lipper has ranked the fund's class A shares in the upper 14% of
         municipal bond funds based on total return for five years ended
         September 30, 1994.+

    --   Performance should always be considered in light of a fund's
         investment strategy. Putnam Municipal Income Fund is designed for
         investors seeking as high a level of current income free from
         federal income tax as is consistent with preservation of capital.

     DEAR SHAREHOLDER:                                    C Karsh, Ottawa

     MUNICIPAL BOND INVESTORS HAVE EXPERIENCED MORE THAN THEIR SHARE OF
     FRUSTRATION OVER THE PAST SEVERAL MONTHS AS THE FIXED-INCOME MARKETS
     ENDURE A PROLONGED PERIOD OF VOLATILITY. PUTNAM MUNICIPAL INCOME FUND'S
     PERFORMANCE DURING THE SIX MONTHS ENDED SEPTEMBER 30, 1994, REFLECTS
     THIS UNSETTLED ENVIRONMENT.

     DESPITE THE LACKLUSTER PERFORMANCE, SOME SIGNS OF ENCOURAGEMENT ARE
     BEGINNING TO APPEAR FOR INVESTORS IN TAX-EXEMPT SECURITIES. SUPPLIES
     MAY BECOME TIGHTER AS MORE INVESTORS SEEK TAX RELIEF, WHICH COULD
     TRANSLATE INTO HIGHER PRICES, PARTICULARLY IF INTEREST RATES DO NOT
     MOVE SIGNIFICANTLY HIGHER. MANY SECTORS OF THE TAX-EXEMPT MARKET,
     INCLUDING HEALTH CARE, EDUCATION, AND RESOURCE RECOVERY, ARE POISED FOR
     GROWTH, WHICH SHOULD BODE WELL OVER THE LONG TERM FOR INVESTMENTS IN
     THOSE AREAS.

     WITH PUTNAM'S CONSIDERABLE CREDIT RESEARCH AND ANALYSIS CAPABILITIES
     BEHIND HIM, FUND MANAGER RICHARD WYKE WILL CONTINUE SEEKING OUT THE
     MOST PROMISING TAX-EXEMPT INVESTMENTS FOR YOUR FUND. RICK'S REPORT ON

REPORT FROM THE FUND MANAGER
RICHARD P. WYKE

     In a period that has been rather inhospitable to most fixed-income
     investments, Putnam Municipal Income Fund proved able to contain much
     of the damage. The higher-yielding bonds in its portfolio helped the
     fund avoid much of the price erosion experienced by funds with a
     heavier emphasis on investment-grade securities in the market decline
     touched off by the Federal Reserve Board's increases in short-term
     interest rates earlier this year.

     For the six months ended September 30, 1994, the fund's class A shares
     provided a total return of 1.34% and class B shares, 0.93%, both at net
     asset value. Results over longer periods are better indicators of the
     fund's potential. As the table on page 8 shows, the fund's total return
     at net asset value for five years and since its inception on May 22,
     1989, are both ahead of the municipal bond market as measured by the
     Lehman Brothers index. The index includes only investment-grade bonds,
     while the fund may invest in lower-rated higher-yielding securities.

     -   STRATEGY: HIGH-YIELD BONDS, HEDGING, SHORTER DURATION

     Early in the period, we began shopping for promising opportunities
     among high-yield bonds. We were attracted to these lower-rated tax-
     exempt securities because institutional investors had become active
     buyers. These investors, particularly insurance companies, were
     purchasing general obligation securities for long-term investment
     reasons, not short-term market reasons. We reasoned, correctly, that
     this extended investment horizon, coupled by sustained demand, would
     promote near-term price stability.

     During the fund's semiannual period, these bonds outperformed the
     market by more than a quarter of a percentage point. Retail demand, on
     the other hand, was responding more to the volatility in the fixed-
     income markets touched off by the Fed's increases in short-term rates.


4
<PAGE>   5

     While these high-yield holdings insulated the fund's portfolio somewhat
     from the volatility sparked by the rate increases, it was not immune.
     Rather than exchange some of the more rate-sensitive holdings in the
     portfolio with less sensitive ones, we concluded the more cost-
     effective course would be to initiate some hedging tactics. Once in
     place, these hedges, mainly futures contracts, achieved the desired
     result of further reducing the portfolio's overall sensitivity to
     changes in interest rates.

     To protect the fund's value further, we shortened the portfolio's
     average duration. Duration is a mathematical measure of a bond's
     sensitivity to changes in interest rates and, like maturity, is
     expressed in years. The shorter the duration, the less volatility you
     can expect from the portfolio.

     -   RESISTING THE SIREN SONG OF DISCOUNTED SECURITIES

     We also resisted the lure of discounted securities, bonds whose market
     prices had dropped below their par value. Because a bond's stated
     interest rate, or "coupon," is fixed for the life of the security, the
     only way for the market to bring the bond's actual return into line
     with prevailing interest rates is to adjust the selling price. Thus,
     when interest rates fall, bond prices tend to rise; when rates rise,
     prices tend to decline.

     [A line graph comparing the growth of a hypothetical $10,000 investment
     in tax-free municipal bonds with a similar investment in U.S. Treasury
     bonds, and shows the effective after-tax returns of the fully taxable
     Treasury securities for an individual paying the maximum 39.6% federal
     income tax rate.]

     As the rise in short-term interest rates spread over into longer-term
     securities, prices of some bonds declined well below par, the price the
     bond's issuer will pay upon retiring the bond. The difference between
     the acquisition cost and par can sometimes represent alluring capital
     appreciation potential. But recently the market's treatment of these
     bonds has been harsh in the wake of new and more stringent rules on the
     taxation of the potential gains. As a result, these securities have
     underperformed. We did well to avoid them in your fund's portfolio.

     -   SECTOR EMPHASIS: RESOURCE RECOVERY, HEALTH CARE, INDUSTRY

     We continued to add to the resource recovery sector of the municipal
     bond market. Over time, we believe these facilities devoted to
     recycling and converting trash into fuel will gain broader
     acceptability and, therefore, receive higher credit ratings.

     Securities related to health care still make up about 18.41% of the
     fund's net assets, though they have been trimmed back somewhat since
     the start of fiscal 1994. We select them issue by issue, credit by
     credit, rather than investing broadly across the sector. While the
     sector as a whole could well experience further unrest as the national
     debate on reform resumes, we are focusing on issues that appear likely
     to perform well regardless of the ultimate outcome.

     Municipal bonds issued to promote industrial development have benefited
     as a group because of their exposure to improving corporate profits in
     the recovering economy. During the period, we sold some of the higher-
     rated issues because we believed they had become fully valued and were
     approaching the limit of their potential benefit for your portfolio.

     -   OUTLOOK: TIGHT SUPPLY SHOULD BUOY MARKET

     The portfolio is still positioned somewhat defensively. While we
     believe rates on long-term bonds will rise more as the Fed tries to
     contain inflation by notching up short-term rates, we are keeping a
     portion of the portfolio flexible to enable us to participate in
     special situations and other opportunities that might arise.

     Over the past several months, the supply of municipal bonds has
     declined by more than 40% from last year's levels, a trend that is
     likely to continue as fewer municipalities refinance existing bonds and
     cut back on financing new projects. We also believe demand will rise as
     more investors seek relief from higher taxes and increasingly recognize
     the attractiveness of municipal bonds relative to taxable Treasury
     securities.

     We see an economy of slow but steady growth with relatively low
     inflation. Although there can be no guarantees, with properly balanced
     market and sector weightings, we believe the fund can offer you strong
     potential for attractive tax-free income and total return through the
     remainder of fiscal 1995 and beyond.


     The views expressed in this report are exclusively those of Putnam
     Management, and are not meant as investment advice. Although the
     described holdings were viewed favorably as of September 30, 1994,
     there is no guarantee the fund will continue to hold these securities
     in the future.

PERFORMANCE SUMMARY

     This section provides, at a glance, information about your fund's
     performance. Total return shows how the value of the fund's shares
     changed over time, assuming you held the shares through the entire
     period and reinvested all distributions back into the fund. We show
     total return in two ways: on a cumulative long-term basis and on
     average how the fund might have grown each year over varying periods.
     For comparative purposes, we show how the fund performed relative to
     appropriate indexes and benchmarks.

Fund performance data do not take into account any adjustment for taxes
payable on reinvested distributions or, for class A shares, distribution
fees prior to implementation of the class A distribution plan in 1990. The
fund began operations on May 22, 1989, offering shares now known as class A.
Effective January 4, 1993, the fund began offering class B shares.
Performance data represent past results and will differ for each share
class. Investment returns and principal value will fluctuate so an
investor's shares, when sold, may be worth more or less than their original
cost.

TERMS AND DEFINITIONS

CLASS A SHARES are generally subject to an initial sales charge.

CLASS B SHARES may be subject to a sales charge upon redemption.

NET ASSET VALUE (NAV) is the value of all your fund's assets, minus any
liabilities, divided by the number of outstanding shares, not including any
initial or contingent deferred sales charge.

PUBLIC OFFERING PRICE (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance figures
shown here assume the maximum 4.75% sales charge.

CONTINGENT DEFERRED SALES CHARGE (CDSC) is a charge applied at the time of
the redemption of class B shares and assumes redemption at the end of the
period. Your fund's CDSC declines from a 5% maximum during the first year to
1% during the sixth year. After the sixth year, the CDSC no longer applies.

COMPARATIVE BENCHMARKS

LEHMAN BROTHERS MUNICIPAL BOND INDEX is an unmanaged list of  long-term
fixed-rate investment-grade tax-exempt bonds representative of the municipal
bond market. The index does not take into account brokerage commissions or
other costs, may include bonds different from those in the fund, and may
pose different risks than the fund.

CONSUMER PRICE INDEX (CPI) is a commonly used measure of inflation; it does
not represent an investment return.

     NOTES
     ---------------------------------------------------------------------------

(a)  Percentages indicated are based on total net assets of
     $1,250,314,333, which correspond to a net asset value per Class A
     and Class B shares of $8.58 and $8.57, respectively.

(b)  The Moody's or Standard & Poor's ratings indicated are believed to
     be the most recent ratings available at September 30,
     1994 for the securities listed. Ratings are generally ascribed to
     securities at the time of issuance. While the agencies may from time to
     time revise such ratings, they undertake no obligation to do so, and the
     ratings do not necessarily represent what the agencies would ascribe to
     these securities at September 30, 1994. Securities rated by Putnam are
     indicated by "/P" and are not publicly rated.

(c)  Restricted as to public resale. At the date of acquisition, these
     secutities were valued at cost. There were no
     outstanding unrestricted securities of the same class as those held. The
     total market value of the restricted securities owned at September 30,
     1994 was $33,168,250 or 2.7% of net assets.

(d)  Non-Income-producing security.

(e)  This security was pledged to cover margin requirements for futures
     contracts at September 30, 1994. The market value of
     segregated securities with the custodian for transactions on futures
     contracts is $3,977,138.

(f)  This security valued at $5,835,000 or 0.5% of net assets, has
     been purchased on "forward commitment" basis--that is, the Fund has agreed

NOTES TO FINANCIAL STATEMENTS
September 30, 1994 (Unaudited)

NOTE 1
SIGNIFICANT ACCOUNTING POLICIES

The fund is registered under the Investment Company Act of 1940, as amended,
as a diversified, open-end management investment company. The fund seeks as
high a level of current income except from federal income tax as Putnam
Management believes is consistent with the preservation of capital. The fund
is required under normal market conditions to invest at least 65% of its
assets in "investment-grade" tax-exempt securities.

The fund offers both class A and class B shares. The fund commenced its
public offering of class B shares on January 4, 1993. Class A shares are
sold with a maximum front-end sales charge of 4.75%. Class B shares do not
pay a front-end sales charge, but pay a higher ongoing distribution fee than
class A shares, and may be subject to a contingent deferred sales charge if
those shares are redeemed within six years of purchase. Expenses of the fund
are borne pro-rated by the holders of both classes of shares, except that
each class bears expenses unique to that class (including the distribution
fees applicable to such class) and votes as a class only with respect to its
own distribution plan or other matters on which a class vote is required by
law or determined by the Trustees. Shares of each class would receive their
pro-rata share of the net assets of the fund, if the fund were liquidated.
In addition, the Trustees declare separate dividends on each class of
shares.

The following is a summary of significant accounting policies consistently
followed by the fund in the preparation of its financial statements. The
policies are in conformity with generally accepted accounting principles.

A) SECURITY VALUATION Tax-exempt bonds and notes are stated on the basis of
valuations provided by a pricing service, approved by the Trustees, which
uses information with respect to transactions in bonds, quotations from bond
dealers, market transactions in comparable securities and various
relationships between securities in determining value. Short-term
investments having remaining maturities of 60 days or less are stated at
amortized cost, which approximates market value, and other investments,
including restricted securities, are stated at fair value following
procedures approved by the Trustees.

B) SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME Security 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.

C) FUTURES An index futures contract is an agreement between two parties to
buy and sell the cash equivalent of an index at a set price on a future
date. Upon entering into such a contract the fund is required to pledge to
the broker an amount of cash or securities equal to the minimum "initial
margin" requirements of the futuresexchange. Pursuant to the contract, the
fund agrees to receive from or pay to the broker an amount of cash equal to
the daily fluctuation in value of the contract. Such receipts or payments
are known as "variation margin" and are recorded by the fund as unrealized
gains or losses. When the contract is closed, the fund records a realized


30
<PAGE>   31

gain or loss equal to the difference between the value of the contract at
the time it was opened and the value at the time it was closed.

D) FEDERAL TAXES It is the policy of the fund to distribute all of its income
within the prescribed time and otherwise comply with the provisions of the
Internal Revenue Code applicable to regulated investment companies. It is
also the intention of the fund to distribute an amount sufficient to avoid
imposition of any excise tax under Section 4982 of the Internal Revenue Code
of 1986. Therefore, no provision has been made for federal taxes on income,
capital gains or unrealized appreciation of securities held and excise tax
on income and capital gains.

E) DISTRIBUTIONS TO SHAREHOLDERS Income dividends are recorded daily by the
fund and are distributed monthly. Capital gain distributions, if any, are
recorded on the ex-dividend date and paid annually, or as necessary to meet
the distribution requirements described above.

F) AMORTIZATION OF BOND PREMIUM AND DISCOUNT Any premium resulting from the
purchase of securities in excess of maturity value is amortized on a
yield-to-maturity basis. Discount on zero-coupon bonds is accreted according
to the effective yield method.

NOTE 2
MANAGEMENT FEE, ADMINISTRATIVE SERVICES, AND OTHER TRANSACTIONS

Compensation of Putnam Investment Management, Inc. (formerly known as The
Putnam Management Company, Inc.), the fund's Manager, a wholly-owned
subsidiary of Putnam Investments, Inc., (formerly known as The Putnam
Companies Inc.), for management and investment advisory services is paid
quarterly based on the average net assets of the fund. Such fee is based on
the following annual rates: 0.65% of the first $500 million of the fund's
average net assets, 0.55% of the next $500 million, 0.50% of the next $500
million and 0.45% of any amount over $1.5 billion. Fees are subject to
reduction under current law in any year to the extent that expenses
exclusive of brokerage, interest, taxes, deferred organizational and
extraordinary expenses) of the fund exceed 2.5% of the first $30 million
of average net assets, 2.0% of the next $70 million and 1.5% of any amount
over $100 million, and by the amount of certain brokerage commissions and
fees (less expenses) received by affiliates of the Manager on the fund's
portfolio transactions.

The fund also reimburses the Manager for the compensation and related
expenses of certain officers of the fund and their staff who provide
administrative services to the fund. The aggregate amount of all such
reimbursements is determined annually by the Trustees. For the six months
ended September 30, 1994, the fund paid $3,621,788 for these services.

Trustees of the fund receive an annual Trustee's fee of $2,380 and an
additional fee for each Trustees' meeting attended. Trustees who are not
interested persons of the Manager and who serve on committees of the
Trustees receive additional fees for attendance at certain committee
meetings.

Custodial functions for the fund are provided by Putnam Fiduciary Trust
Company (PFTC), a subsidiary of Putnam Investments, Inc. Investor servicing
agent functions are provided by Putnam Investor Services, a division of
PFTC.

Fees paid for these investor servicing and custodial functions for the six
months ended September 30, 1994 amounted to $308,230.

The fund has adopted a distribution plan with respect to class A shares (the
"Class A Plan") pursuant to Rule 12b-1 of the Investment Company Act of
1940. The purpose of the Class A Plan is to compensate Putnam Mutual

31
<PAGE>   32

Funds Corp., a wholly owned subsidiary of Putnam Investments, Inc., for
services provided and expenses incurred in distributing class A shares. The
Trustees have approved payments by the fund to Putnam Mutual Funds Corp. at
an annual rate of 0.25% of average net assets attributable to class A
shares. For the period ended September 30, 1994, the fund paid $1,069,668 in
distribution fees for class A shares.

During the six months ended September 30, 1994, Putnam Mutual Funds Corp.,
acting as the underwriter, received net commissions of $105,190 from the
sale of class A shares of the fund.

A deferred sales charge of up to 1% is assessed on certain redemptions of
class A shares purchased as part of an investment of $1 million or more. For
the six months ended September 30, 1994, Putnam Mutual Funds Corp., acting
as the underwriter, received $6,813 on such redemptions.

The fund has adopted a separate distribution plan with respect to its class
B shares (the "Class B Plan") pursuant to Rule 12b-1 under the Investment
Company Act of 1940. The purpose of the Class B Plan is to compensate Putnam
Mutual Funds Corp. for services provided and expenses incurred by it in
distributing class B shares. The Class B Plan provides for payments by the
fund to Putnam Mutual Funds Corp. at an annual rate of up to 1.00% of the
fund's average net assets attributable to class B shares. Currently, the
Trustees have limited payments to .85% of such assets. For the six months
ended September 30, 1994, the fund paid Putnam Mutual Funds Corp.
distribution fees of $1,669,837 for class B shares.

Putnam Mutual Funds Corp. acting as the underwriter, also receives the
proceeds of the contingent deferred sales charges levied on class B share
redemptions within six years of purchase. The charge is based on declining
rates, which begin at 5.0% of the net asset value of the redeemed shares.
Putnam Mutual Funds Corp. received $402,370 in contingent deferred sales
charges from such redemptions for the six months ended September 30, 1994.

NOTE 3
PURCHASES AND SALES OF SECURITIES

During the six months ended September 30, 1994, purchases and sales of
investment securities other than short-term municipal obligations aggregated
$367,783,463 and $327,945,158, respectively. Purchases and sales of
short-term municipal obligations aggregated $133,696,150 and $136,446,800,
respectively. In determining the net gain or loss on securities sold, the
cost of securities has been determined on the identified cost basis.

OUR COMMITMENT TO QUALITY SERVICE




- -   CHOOSE AWARD-WINNING SERVICE.
Putnam Investor Services has won the DALBAR Quality Tested Service Seal
every year since the award's 1990 inception.  DALBAR, an independent research
firm, ran more than 10,000 tests of 38 shareholder service components. In every
category, Putnam outperformed the industry standard.

- -   HELP YOUR INVESTMENT GROW.
Set up a systematic program for investing with as little as $25 a month from a
Putnam fund or from your checking or savings account.*
        
- -   SWITCH FUNDS EASILY.
You can move money from one account to another with the same class of shares
without a service charge. (This privilege is subject to change or termination.)

- -   ACCESS YOUR MONEY QUICKLY.
You can get checks sent regularly or redeem shares any business day at the
then-current net asset value, which may be more or less than their original
cost.

For details about any of these or other services, contact your financial
advisor or call the toll-free number shown below and speak with a helpful
Putnam representative.

- -   To make an additional investment in this or any other Putnam fund,
contact your financial advisor or call our toll-free number:  1-800-225-1581.

*    Regular investing, of course, does not guarantee a profit or protect
against a loss in a declining market. Investors should consider their ability
to continue purchasing shares during periods of low price levels.
