Putnam Managed Municipal Income Trust Item 1. Report to Stockholders: ------------------------------- The following is a copy of the report transmitted to stockholders pursuant to Rule 30e-1 under the Investment Company Act of 1940: SEMIANNUAL REPORT ON PERFORMANCE AND OUTLOOK 4-30-03 [GRAPHIC OMITTED: WATCH] [SCALE LOGO OMITTED] FROM THE TRUSTEES [GRAPHIC OMITTED: PHOTO OF JOHN A. HILL AND GEORGE PUTNAM, III] Dear Fellow Shareholder: We are pleased to bring you news of positive performance by Putnam Managed Municipal Income Trust for the semiannual period ended April 30, 2003. Your fund outperformed its benchmark index and came in well ahead of its peers as measured by its Lipper category average. You will find details on page 7. As you will see in the following report from your fund's management team, these results were achieved in large measure by the fund's duration strategy and a generally favorable interest-rate environment during the period. Duration is a measure of a fund's sensitivity to changes in interest rates. The fund's weighting in high-quality bonds also enhanced results as the demand for these securities by risk-averse investors helped elevate their prices. The management team also offers its views on prospects for the fund in the fiscal year's second half. As we look back on one of the most challenging periods in recent investment history, we would like you to know how much we appreciate your continued confidence in Putnam. We believe that those who ride out the current turbulence will be rewarded for their patience over the long term. Respectfully yours, /S/ JOHN A. HILL /S/ GEORGE PUTNAM, III John A. Hill George Putnam, III Chairman of the Trustees President of the Funds June 18, 2003 REPORT FROM FUND MANAGEMENT FUND HIGHLIGHTS * For the first six months of its fiscal year, Putnam Managed Municipal Income Trust had a total return at net asset value of 5.44%. The fund's return at market price was 5.95%. * The fund's longer duration helped it to outperform its benchmark, the Lehman Municipal Bond Index, which returned 3.59% for the six-month period. * The fund's duration and portfolio mix of high- and lower-quality bonds helped it outperform the average return for its Lipper category, High Yield Municipal Debt Funds, which was 3.14%. * Index and Lipper results should be compared to fund performance at net asset value. See the Performance Summary on page 7 for complete fund performance, comparative index performance, and Lipper data. PERFORMANCE COMMENTARY The fund's solid returns were due in large part to a duration strategy that made it more responsive to changes in interest rates relative to its benchmark and many of its peers. (Duration is a measure of interest-rate sensitivity; the longer its duration, the more responsive the portfolio will be to rate changes.) Our high-quality bond position also proved to be an asset, as investors continued to prefer relatively secure investments amidst the uncertainty at home and abroad. Consequently, lower-rated bonds, which contribute considerably to the portfolio's monthly income, underperformed their higher-quality counterparts. This disparity in the performance of higher- and lower-rated municipal securities is exhibited by the fact that credit spreads -- the difference in bond yields at either end of the credit quality spectrum -- widened for much of the six-month period. The fund's results should also be considered in the context of a generally favorable interest-rate environment. However, after a three-year rally in fixed-income investments, the markets are beginning to ponder the return of higher interest rates. We've been gradually positioning the fund for this possibility to limit the price depreciation that typically accompanies a rising-rate market. FUND PROFILE Putnam Managed Municipal Income Trust seeks to provide as high a level of current income free from federal income tax as is consistent with preservation of capital through investments in investment-grade and higher-yielding, lower-rated municipal bonds. The fund is designed for investors seeking tax-exempt income and willing to accept the risks associated with below-investment-grade bonds. MARKET OVERVIEW In what was a challenging semiannual period, municipal-bond yields fell slightly, resulting in modest returns overall. Municipal bonds slightly outperformed Treasuries for the period. Several factors contributed to the difficult environment. The sluggish economy caused many state and local municipalities to experience significant declines in tax revenues and subsequent downgrades in credit quality. Difficulties in two sectors -- airlines and utilities -- dampened the performance of industrial development bonds (IDBs), which are issued by municipalities but backed by the credit of companies. Airline-backed IDBs suffered as United Airlines followed US Airways into bankruptcy. In late April, American Airlines narrowly avoided a similar fate. The electric power sector came under pressure, affecting performance of utility IDBs as well. Lastly, the supply of municipal bonds grew throughout 2002. In terms of supply, the California Department of Water Resources' bond issue was the largest ever brought to market. New tobacco settlement bonds further boosted supply. All told, over $320 billion in municipal bonds was issued in 2002 -- an all-time record. Supply has continued to swell in 2003, and has had a dampening effect on municipal-bond prices.

STRATEGY OVERVIEW The fund maintained its moderate exposure to higher-yielding securities. We positioned the portfolio defensively in anticipation of the October sell-off, but later returned to a more neutral stance by extending the fund's duration. We diversified the fund further, and increased its exposure to California tax-exempt bonds. We also reduced exposure to tobacco settlement bonds, discussed further on page 5. During the period, tax-exempt municipal bonds offered investors almost the same yield as comparable Treasury bonds. This was an unusual situation, and we expect the yield ratios will return to normal levels as the supply of municipal offerings moderates and demand increases. To take advantage of this opportunity, we established a cross-market arbitrage position, in which we bought intermediate-term municipal bonds and shorted 10-year Treasury futures contracts. Our thesis is that if interest rates should rise (causing bond prices to fall), the fund would have a loss on the municipal bonds, and yet, potential gains on the Treasury futures contracts may more than compensate for the loss. On the other hand, if rates should fall (causing bond prices to rise), a loss on the Treasury futures contracts may be mitigated by a gain on the municipal bonds.

HOW KEY HOLDINGS AND ALLOCATIONS AFFECTED THE FUND'S PERFORMANCE While the fund holds over 75% of its assets in high-quality investment-grade bonds, it does selectively downgrade when the right market conditions and investment opportunities present themselves. We think the fund's position in lower-rated municipal bonds, which have been out of favor for some time, is advantageous at this point and we believe these bonds can perform well in the coming months, especially as the economy recovers. We've seen a large supply of uninsured investment-grade hospital bonds come to market in recent months, improving the number and quality of prospects for your portfolio. In addition to refinancing older, more expensive debt at today's historically low interest rates, hospitals in high-growth locations are requiring more resources to finance their expansion in order to meet increasing patient demand. Furthermore, hospitals are becoming more specialized and moving beyond their core medical services. This trend has meant that hospitals are developing a niche in such fields as cardiology or oncology. Several issues in the A to BBB credit-quality range were attractive to us. Recent purchases include Mother Frances Hospital bonds, which were issued by Tyler Health Facilities Corp. in Texas. These bonds are helping to finance a new facility that will serve a growing population and a large cardiac business, which we expect to improve operating revenues. The fund also holds the A-rated Cleveland Clinic Health System bonds, issued by Cuyahoga County. The Cleveland Clinic, which serves northeast Ohio and southwest Florida, has a medical and educational reputation on par with Johns Hopkins and the Mayo Clinic. While the Cleveland Clinic previously incurred investment losses, we believe the steady, high-quality delivery of its core health services in its target markets should eventually restore much of its diminished cash flow.

A bond rated Baa or higher is considered investment grade. The chart reflects Moody's and Standard & Poor's ratings; percentages may include unrated bonds considered by Putnam Management to be of comparable quality. Ratings will vary over time. The electric power sector is another industry undergoing great change, providing unique investment opportunities as it transforms itself. In the aftermath of the power crisis in 2002, utility companies that strayed into non-utility-related activities such as telecommunications are in the process of refocusing on their core business of power generation and distribution. Overall, we think this trend is a positive one that will contribute to improvements in credit-quality ratings throughout the sector. The fund's A2-rated Georgia Power Company bonds, issued by Burke County, exemplify this trend. This electric utility owns its own generation resources, receives 88% of its revenues from cost-based regulated rates, and has a history of regulatory support. Tobacco settlement bonds, which are issued by municipalities and secured by cash payments made in satisfaction of legal judgments against the tobacco industry, are a relatively new class of municipal securities, which we always approach with caution. These bonds tend to be higher-quality debt, but because they are subject to special risks, they generally offer higher yields than other bonds of comparable quality. During the reporting period, we reduced the fund's exposure to tobacco settlement bonds, due to concerns about the market becoming overwhelmed by the growing supply of new issuance. Please note that all holdings discussed in this report are subject to review in accordance with the fund's investment strategy and may vary in the future. THE FUND'S MANAGEMENT TEAM The fund is managed by the Putnam Tax Exempt Fixed-Income Team. The members of the team are Richard Wyke (Portfolio Leader), Paul Drury (Portfolio Member), David Hamlin (Portfolio Member), Susan McCormack (Portfolio Member), Joyce Dragone, and Jerome Jacobs. THE OUTLOOK FOR YOUR FUND The following commentary reflects anticipated developments that could affect your fund over the next six months, as well as the fund's management team's plans for responding to them. Our current outlook for the municipal-bond market is cautiously optimistic. Fear of war has subsided. The focus is now on rebuilding Iraq and addressing economic concerns on the home front. While much remains to be answered, the level of uncertainty in the world seems to have eased a bit. We expect business activity will accelerate slowly. Although the tax-free marketplace is certainly not immune to the forces that buffet other markets, it has historically been less volatile. We believe municipal bonds should perform well relative to other fixed-income sectors as some measure of calm returns to financial markets. We believe that municipal budgets will continue to face significant pressures in the months ahead. And we believe that governments will need to determine how to implement costly home-front protection measures while at the same time pushing tax cuts to stimulate economic growth. Historically, improvement in the credit quality of state and local governments has lagged a general economic recovery by six to nine months, so we expect municipal credit quality to remain fragile for some time to come. Currently, municipal-bond yields remain unusually high relative to yields on taxable issues. In time, we expect that relationship will revert to a normal range. In our opinion, the market continues to offer attractive value and compelling risk/reward characteristics. We believe that we have positioned your fund to take advantage of this potential.

TERMS AND DEFINITIONS 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 in the fund. Net asset value (NAV) is the value of all your fund's assets, minus any liabilities and the net assets allocated to remarketed preferred shares, divided by the number of outstanding common shares. Market price is the current trading price of one share of the fund. Market prices are set by transactions between buyers and sellers on the New York Stock Exchange.

A GUIDE TO THE FINANCIAL STATEMENTS These sections of the report, as well as the accompanying Notes, constitute the fund's financial statements. The fund's portfolio lists all the fund's investments and their values as of the last day of the reporting period. Holdings are organized by asset type and industry sector, country, or state to show areas of concentration and diversification. Statement of assets and liabilities shows how the fund's net assets and share price are determined. All investment and noninvestment assets are added together. Any unpaid expenses and other liabilities are subtracted from this total. The result is divided by the number of shares to determine the net asset value per share, which is calculated separately for each class of shares. (For funds with preferred shares, the amount subtracted from total assets includes the net assets allocated to remarketed preferred shares.) Statement of operations shows the fund's net investment gain or loss. This is done by first adding up all the fund's earnings -- from dividends and interest income -- and subtracting its operating expenses to determine net investment income (or loss). Then, any net gain or loss the fund realized on the sales of its holdings -- as well as any unrealized gains or losses over the period -- is added to or subtracted from the net investment result to determine the fund's net gain or loss for the fiscal period. Statement of changes in net assets shows how the fund's net assets were affected by distributions to shareholders and by changes in the number of the fund's shares. It lists distributions and their sources (net investment income or realized capital gains) over the current reporting period and the most recent fiscal year-end. The distributions listed here may not match the sources listed in the Statement of operations because the distributions are determined on a tax basis and may be paid in a different period from the one in which they were earned. Financial highlights provide an overview of the fund's investment results, per-share distributions, expense ratios, net investment income ratios, and portfolio turnover in one summary table, reflecting the five most recent reporting periods. In a semiannual report, the highlight table also includes the current reporting period. For open-end funds, a separate table is provided for each share class.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to be the most recent ratings available at April 30, 2003 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 April 30, 2003. Securities rated by Putnam are indicated by "/P" and are not publicly rated. (NON) Non-income-producing security. (RES) Restricted, excluding 144A securities, as to public resale. The total market value of restricted securities held at April 30, 2003 was $32,900,394 or 6.2% of portfolio market value. (SEG) A portion of this security was pledged and segregated with the custodian to cover margin requirements for futures contracts at April 30, 2003. 144A after the name of a security represents those exempt from registration under Rule 144A of the Securities Act of 1933.

NOTES TO FINANCIAL STATEMENTS April 30, 2003 (Unaudited) Note 1 Significant accounting policies Putnam Managed Municipal Income Trust (the "fund") is registered under the Investment Company Act of 1940, as amended, as a diversified, closed-end management investment company. The fund's investment objective is to seek a high level of current income exempt from federal income tax. The fund intends to achieve its objective by investing in a diversified portfolio of tax-exempt municipal securities which Putnam Investment Management, LLC ("Putnam Management"), the fund's manager, an indirect wholly-owned subsidiary of Putnam, LLC, believes does not involve undue risk to income or principal. Up to 50% of the fund's assets may consist of high-yield tax-exempt municipal securities that are below investment grade and involve special risk considerations. The fund also uses leverage by issuing preferred shares in an effort to increase the income to the common shares. The following is a summary of significant accounting policies consistently followed by the fund in the preparation of its financial statements. The preparation of financial statements is in conformity with accounting principles generally accepted in the United States of America and requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. A) Security valuation Tax-exempt bonds and notes are valued on the basis of valuations provided by an independent pricing service, approved by the Trustees. Such services use information with respect to transactions in bonds, quotations from bond dealers, market transactions in comparable securities and various relationships between securities in determining value. Restricted securities are valued at fair value following procedures approved by the Trustees. Such valuations and procedures are reviewed periodically by the Trustees. B) Security transactions and related investment income Security transactions are recorded on the trade date (date the order to buy or sell is executed). Gains or losses on securities sold are determined on the identified cost basis. Interest income is recorded on the accrual basis. All premiums/discounts are amortized/accreted on a yield-to-maturity basis. The premium in excess of the call price, if any, is amortized to the call date; thereafter, any remaining premium is amortized to maturity. C) Futures and options contracts The fund may use futures and options contracts to hedge against changes in the values of securities the fund owns or expects to purchase. The fund may also write options on securities it owns or in which it may invest to increase its current returns. The potential risk to the fund is that the change in value of futures and options contracts may not correspond to the change in value of the hedged instruments. In addition, losses may arise from changes in the value of the underlying instruments, if there is an illiquid secondary market for the contracts, or if the counterparty to the contract is unable to perform. When the contract is closed, the fund records a realized 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. Realized gains and losses on purchased options are included in realized gains and losses on investment securities. Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. The fund and the broker agree to exchange an amount of cash equal to the daily fluctuation in the value of the futures contract. Such receipts or payments are known as "variation margin." Exchange traded options are valued at the last sale price, or if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by dealers. Futures and written option contracts outstanding at period end are listed after The fund's portfolio. 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, as amended. Therefore, no provision has been made for federal taxes on income, capital gains or unrealized appreciation on securities held nor for excise tax on income and capital gains. At October 31, 2002, the fund had a capital loss carryover of approximately $24,642,000 available to the extent allowed by tax law to offset future capital gains, if any. The amount of the carryover and the expiration dates are: Loss Carryover Expiration ------------------------------------ $321,000 October 31, 2003 11,188,000 October 31, 2005 2,895,000 October 31, 2006 3,629,000 October 31, 2007 1,237,000 October 31, 2008 1,642,000 October 31, 2009 3,730,000 October 31, 2010 The aggregate identified cost on a tax basis is $560,196,631, resulting in gross unrealized appreciation and depreciation of $26,642,818 and $52,429,919, respectively, or net unrealized depreciation of $25,787,101. E) Distributions to shareholders Distributions to common and preferred shareholders from net investment income are recorded by the fund on the ex-dividend date. Distributions from capital gains, if any, are recorded on the ex dividend date and paid at least annually. Dividends on re marketed preferred shares become payable when, as and if declared by the Trustees. Each dividend period for the remarketed preferred shares is generally a 28-day period for Series A and Series B shares, and a 7-day period for Series C shares. The applicable dividend rate for the remarketed preferred shares on April 30, 2003 was 1.08% for Series A, 1.09% for Series B and 1.19% for Series C. The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Reclassifications are made to the fund's capital accounts to reflect income and gains available for distribution (or available capital loss carryovers) under income tax regulations. F) Determination of net asset value Net asset value of the common shares is determined by dividing the value of all assets of the fund, less all liabilities and the liquidation preference of any outstanding remarketed preferred shares, by the total number of common shares outstanding as of period end. Note 2 Management fee, administrative services and other transactions Putnam Management is paid for management and investment advisory services quarterly based on the average net assets of the fund. Such fee is based on the following annual rates: 0.70% of the first $500 million of the average weekly net assets, 0.60% of the next $500 million, 0.55% of the next $500 million and 0.50% thereafter. If dividends payable on remarketed preferred shares during any dividend payment period plus any expenses attributable to remarketed preferred shares for that period exceed the fund's gross income attributable to the proceeds of the remarketed preferred shares during that period, then the fee payable to Putnam Management for that period will be reduced by the amount of the excess (but not more than .70% of the liquidation preference of the remarketed preferred shares outstanding during the period). The fund reimburses Putnam Management an allocated amount 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. Custodial functions for the fund's assets are provided by Putnam Fiduciary Trust Company (PFTC), a wholly-owned subsidiary of Putnam, LLC. Investor servicing agent functions are provided by Putnam Investor Services, a division of PFTC. The fund has entered into an arrangement with PFTC whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the fund's expenses. For the six months ended April 30, 2003, the fund's expenses were reduced by $10,781 under these arrangements. Each independent Trustee of the fund receives an annual Trustee fee, of which $737 has been allocated to the fund, and an additional fee for each Trustees meeting attended. Trustees receive additional fees for attendance at certain committee meetings. The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan") which allows the Trustees to defer the receipt of all or a portion of Trustees fees payable on or after July 1, 1995. The deferred fees remain invested in certain Putnam funds until distribution in accordance with the Deferral Plan. The fund has adopted an unfunded noncontributory defined benefit pension plan (the "Pension Plan") covering all Trustees of the fund who have served as a Trustee for at least five years. Benefits under the Pension Plan are equal to 50% of the Trustee's average total retainer and meeting fees for the three years preceding retirement. Pension expense for the fund is included in Compensation of Trustees in the Statement of operations. Accrued pension liability is included in Payable for compensation of Trustees in the Statement of assets and liabilities. Note 3 Purchases and sales of securities During the six months ended April 30, 2003, cost of purchases and proceeds from sales of investment securities other than short-term investments aggregated $89,403,022 and $77,040,786, respectively. There were no purchases and sales of U.S. government obligations. Note 4 Preferred shares The Series A (550), Series B (550) and Series C (650) shares are redeemable at the option of the fund on any dividend payment date at a redemption price of $100,000 per share, plus an amount equal to any dividends accumulated on a daily basis but unpaid through the redemption date (whether or not such dividends have been declared) and, in certain circumstances, a call premium. Under the Investment Company Act of 1940, the fund is required to maintain asset coverage of at least 200% with respect to the remarketed preferred shares as of the last business day of each month in which any such shares are outstanding. Additionally, the fund is required to meet more stringent asset coverage requirements under terms of the remarketed preferred shares and the shares' rating agencies. Should these requirements not be met, or should dividends accrued on the remarketed preferred shares not be paid, the fund may be restricted in its ability to declare dividends to common shareholders or may be required to redeem certain of the remarketed preferred shares. At April 30, 2003, no such restrictions have been placed on the fund.
