Putnam Managed Municipal Income Trust SEMIANNUAL REPORT ON PERFORMANCE AND OUTLOOK 4-30-02 [SCALE LOGO OMITTED] FROM THE TRUSTEES [GRAPHIC OMITTED: PHOTO OF JOHN A. HILL AND GEORGE PUTNAM III] Dear Fellow Shareholder: In a market environment unsettled by the residual anxiety of the September 11 terrorist attacks, the collapse of Enron, and the new set of uncertainties created by unrest in the Middle East, Putnam Managed Municipal Income Trust posted negative results during the semiannual period ended April 30, 2002. On the following pages, the report from your fund's management team will provide a full review of what has been driving fund performance, including a discussion of the reasons for the underperformance. The team also presents its view of prospects for the remainder of fiscal 2002. You may notice as you read this report that we are now listing the team that manages your fund. We do this to reflect more accurately how your fund is managed as well as Putnam's firm belief in the value of team management. The names of the individuals who comprise the management team are shown at the end of Management's discussion of performance. We know that Putnam Investments values its relationship with you and its other shareholders and appreciates your loyalty during these times of restructuring of staff and products in the pursuit of superior investment performance in the future. 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 19, 2002 REPORT FROM FUND MANAGEMENT This fund is managed by the Putnam Tax Exempt Fixed-Income Team Terrorist attacks, dramatic rebounds and selloffs, and, finally, a wavering recovery were all part of Putnam Managed Municipal Income Trust's turbulent semiannual period ended April 30, 2002. In the first half of the period, the Federal Reserve Board concluded its easing of short-term interest rates, bringing them down to a forty-year low by the end of calendar 2001. This contributed to a steep yield curve and a generally positive bond market for most of the period. Later, the Fed shifted its bias to neutral as the economy showed some signs of strength, although spotty corporate earnings and concerns about shady corporate accounting practices kept investors uncertain in the last half of the semiannual period. In the end, the fund's total return for the six-month period trailed both its Lipper category average and benchmark, as the fund's overweighting in lower-rated, higher-yielding bonds hurt performance in the months after the terrorist attacks on September 11, 2001. While these lower-rated bonds detracted from performance, we believe they will rebound as the economy improves, providing not just high current income but price appreciation as well. Total return for 6 months ended 4/30/02 NAV Market price ----------------------------------------------------------------------- -0.11% -3.94% ----------------------------------------------------------------------- Past performance does not indicate future results. Performance based on market prices for the shares will vary from performance based on the portfolio's net asset value. Performance information for longer periods begins on page 7. * HEALTH-CARE HOLDINGS HELPED DIVERSIFY FUND Over the period, we used bottom-up, issue-by-issue analysis to make smaller, more numerous purchases in an effort to diversify and protect the fund's portfolio. These smaller investments seek to guard against the rise in single-issue risk, as investors, spooked by the terrorist attacks and widely reported examples of corporate malfeasance, have been tending to overreact to the slightest rumor about a security. The health-care sector has provided many of these smaller, less concentrated positions. One example is an issue from New Jersey Health Care Facilities Financing Authority for Atlantic City Medical Center (coupon 5.75%, maturity 7/01/2025). Atlantic City MC has a dominant market share of 72% and is a sole provider in its primary market area. Management is focusing future growth on capturing patient migration from the area to facilities in Camden and Philadelphia, over an hour away. Most patients leave the area for cardiac, vascular, and thoracic services, as well as women's and newborn services. Cardiac services were recently added, and thoracic and OB physicians are being recruited. This is a significant opportunity to increase revenue and cash flow. Also among our recent purchases were bonds issued by the Health, Educational and Housing Facility Board of the County of Shelby, Tennessee (coupon 6.5%, maturity 9/01/2026) for Methodist Healthcare of Memphis. Methodist Healthcare is the number one provider in Memphis, and has good geographic coverage in the area. It controls the mortgages on three key Memphis facilities and is run by a solid management team.

Ratings will vary over time. * AIRLINES PROVIDE BUMPY RIDE WHILE HIGHLIGHTING FUND'S STRENGTHS The trials and troubles of the airline industry provide an illustration of the value added by Putnam's research capabilities and long-term investment focus. Although certainly not the largest sector of the portfolio, airlines and airport authority bonds have represented a significant portion of your fund's holdings in years past. These bonds have a history of high current income and have been one of the most liquid sectors of the municipal bond market. However, perceptions of these bonds changed drastically on September 11, 2001. Airline-backed securities were hurt significantly, including those in your fund's portfolio. Maintaining calm amidst the widespread concern, your fund's management team took full advantage of the research capabilities available to it. Existing airline holdings were analyzed on an issue-by-issue basis, considering creditworthiness while factoring in the top-down issues of airline industry restructuring in the post-crisis environment and the influx of federal relief dollars. As a result of this reevaluation, we decided to trim the fund's airline-related positions only slightly in expectation of a long-term rebound. While we expect further losses for the airlines in 2002, our airline holdings continue to pay their coupons and signs are pointing to a bottom and eventual recovery for the industry. Airline travel was down a third in October of 2001; however, it was down only 10 percent later in the period, based on lower industry-wide capacity. Demand, induced by fare cuts, continues to grow and our expectation is for airlines to increase their bond issuance sometime in the coming year. Volatile oil prices stalled the recovery in the last couple of months of the period but we believe that with the continued assurance of government relief money that our airline holdings will continue to be a good investment. Our initial analysis proved its effectiveness as the airline sector was one of the strongest-performing areas of the portfolio in the last half of the period. 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 suitable for investors seeking tax-exempt income and willing to accept the risks associated with below-investment-grade bonds. * MUNI BOND MARKETS STABLE RELATIVE TO OTHER INVESTMENTS The municipal bond market as a whole remained relatively stable during the period despite the fallout from New York's terrorist attacks. New York City, thanks in part to generous federal assistance, has had no problems meeting its debt obligations although the prices of its bonds have declined. From a bond investor's perspective, the New York City picture is now less focused on the aftermath of the attacks and more concerned with opportunity for undervalued bond issues in the coming months. The city's reputation among muni-bond investors has been bolstered by financial disclosure statutes put in place after the city's budget crisis in the 1970s. Your fund's management team has been extremely cautious in the purchase of General Obligation bonds, which are secured by tax revenues, from issuers nationwide. As the economy recovered slowly over most of the period, tax revenues dropped and many states and municipalities moved from surplus to deficit status, issuing bonds to make up the difference. We have found great valuations nationally in bonds backed by the distribution of proceeds from the tobacco industry's settlement with individual states. These bonds are consistently rated single As with yields at the level of BBB hospital bonds. Based on analysis of the tobacco industry's current growth levels and the outcome of recent court cases, we believe these bonds will continue to be stable investments. * OUTLOOK CAUTIOUS IN COMING SIX MONTHS In the near term, we remain cautious on rates. Our view is that the economy may continue to struggle in its recovery, which should keep the Federal Reserve from tightening interest rates until it sees a credible threat of inflation. Right now there is no such threat, and for the first four months of 2002, the Fed has appeared more concerned about the progress of the recovery than about inflation. Since the capital markets have retracted, with significant declines in capital spending and corporate investment, this lack of funding is in itself a restraint on the economy. As a result, we believe the Fed may hold off on tightening even if growth begins to pick up. Over the longer term, we feel that the national profile of municipal bonds has been raised and believe that the days of aggressive stock investing have given way to an understanding of the importance of asset allocation within investors' portfolios. We believe fixed-income investments and municipal bonds in particular will benefit. Later, as the Enron scandal fades and the economy improves, high-yield municipals -- which are less sensitive to interest-rate increases and perform better in a growing economy -- should bolster the return of your fund. Because of the fund's high-yield exposure, we think it will end up with a competitive advantage relative to its peers. The views expressed here are exclusively those of Putnam Management. They are not meant as investment advice. Although the described holdings were viewed favorably as of 4/30/02, there is no guarantee the fund will continue to hold these securities in the future. Government securities guarantee principal and interest; mutual funds that invest in these securities are not guaranteed. Mortgage-backed securities are subject to prepayment risk. This fund is managed by the Putnam Tax Exempt Fixed-Income Team. The members of the team are Jerome Jacobs, Blake Anderson, Joyce Dragone, David Hamlin, Susan McCormack, and Richard Wyke.

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. COMPARATIVE BENCHMARKS Lehman Municipal Bond Index is an unmanaged index of long-term fixed-rate investment-grade tax-exempt bonds. Indexes assume reinvestment of all distributions and do not account for fees. Securities and performance of a fund and an index will differ. You cannot invest directly in an index. Consumer price index (CPI) is a commonly used measure of inflation; it does not represent an investment return. Lipper Inc. is a third-party industry ranking entity that ranks funds (without sales charges) with similar current investment styles or objectives as determined by Lipper. 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.

NOTES TO FINANCIAL STATEMENTS April 30, 2002 (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 stated on the basis of valuations provided by an independent 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. Restricted securities are stated 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 accounted for 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, the remaining excess 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 agrees to receive from or pay to the broker 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. 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, 2001, the fund had a capital loss carryover of approximately $22,799,000 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 -------------- ------------------ $ 1,887,000 October 31, 2002 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 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 remarketed 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, respectively, and a 7-day period for Series C shares. The applicable dividend rate for the remarketed preferred shares on April 30, 2002 was 1.55% for Series A, 1.42% for Series B and 1.60% 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. Note 2 Management fee, administrative services and other transactions Compensation of Putnam Management, 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: 0.70% 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 0.70% 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, 2002, the fund's expenses were reduced by $23,296 under these arrangements. Each independent Trustee of the fund receives an annual Trustee fee, of which $643 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, 2002, cost of purchases and proceeds from sales of investment securities other than short-term investments aggregated $68,198,902 and $63,220,062, respectively. There were no purchases and sales of U.S. government obligations. Note 4 Remarketed 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 accrued 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, 2002, no such restrictions have been placed on the fund. Under Emerging Issues Task Force (EITF) promulgation Topic D-98, Classification and Measurement of Redeemable Securities, which was issued on July 19, 2001, preferred securities that are redeemable for cash or other assets are to be classified outside of permanent equity to the extent that the redemption is at a fixed or determinable price and at the option of the holder or upon the occurrence of an event that is not solely within the control of the issuer. Subject to the guidance of the EITF, the Trust's preferred stock, which was previously classified as a component of net assets, has been reclassified outside of permanent equity (net assets) in the accompanying financial statements. Prior year amounts have also been reclassified to conform with this presentation. The impact of this reclassification creates no change to the net assets available to common shareholders. Note 5 New accounting pronouncement As required, effective January 1, 2001, the fund has adopted the provisions of the AICPA Audit and Accounting Guide, Audits of Investment Companies. This Guide requires that the fund amortize premium and accrete discount on all fixed-income securities, and classify as interest income gains and losses realized on paydowns on mortgage-backed securities. Prior to November 1, 2001, the fund did not accrete discounts for certain fixed income securities. Adopting these accounting principles will not affect the fund's net asset value, but will change the classification of certain amounts between interest income and realized and unrealized gain/loss in the Statement of operations. The adoption of this principle is not material to the financial statements.
