Putnam Michigan Tax Exempt Income Fund 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 11-30-04 [GRAPHIC OMITTED: PINECONES] [SCALE LOGO OMITTED] From the Trustees [GRAPHIC OMITTED: PHOTO OF JOHN A. HILL AND GEORGE PUTNAM, III] John A. Hill and George Putnam, III Dear Fellow Shareholder: During the past several months, Putnam has introduced a number of reforms for the benefit of shareholders, including enhanced disclosure about your fund. For example, in the spring of 2004 we began showing expense and risk comparisons in shareholder reports. We are now including in this report portfolio turnover information for your fund, which explains how the rate at which a fund buys and sells portfolio securities might affect its return and its taxable distributions to shareholders. We are also including additional disclosure about your fund's management team. Following the section entitled, "The outlook for your fund," we list any changes regarding your fund's Portfolio Leader and Portfolio Members during the prior year period, as well as information about the current Portfolio Leader's and Portfolio Members' other fund management responsibilities at Putnam. We also show how much these individuals have invested in the fund (in dollar ranges). Fund ownership (in dollar ranges) is also shown for the members of Putnam's Executive Board. We are also pleased to announce that three new Trustees have joined your fund's Board of Trustees. Nominated by your fund's independent Trustees, these individuals have had outstanding careers as leaders in the investment management industry. Myra R. Drucker is a Vice Chair of the Board of Trustees of Sarah Lawrence College and serves as Chair of the New York Stock Exchange (NYSE) Pension Managers Advisory Committee and as a Trustee of Commonfund, a not-for-profit asset management firm. Richard B. Worley is Managing Partner of Permit Capital LLC, an investment management firm. Both Ms. Drucker and Mr. Worley are independent Trustees (i.e., Trustees who are not "interested persons" of your fund or its investment advisor). Charles E. Haldeman, Jr., the third new Trustee, is President and Chief Executive Officer of Putnam Investments. During the period covered by the following report, Putnam Michigan Tax Exempt Income Fund delivered respectable results. In the following pages, the fund's management discusses fund performance, strategy, and its outlook for the remainder of fiscal 2005. We thank you for your support of the Putnam funds throughout 2004 and wish you all the best in 2005. Respectfully yours, /S/ JOHN A. HILL /S/ GEORGE PUTNAM, III John A. Hill George Putnam, III Chairman of the Trustees President of the Funds January 19, 2005 Report from Fund Management Fund highlights * For the six months ended November 30, 2004, Putnam Michigan Tax Exempt Income Fund's class A shares returned 3.57% without sales charges and -1.09% with maximum sales charges reflected. * The fund's benchmark, the Lehman Municipal Bond Index, returned 4.29% during the same period. * The average return for the fund's Lipper category, Michigan Municipal Debt Funds, was 3.50%. * See the Performance Summary beginning on page 10 for additional fund performance, comparative performance, and Lipper data. - -------------------------------------------------- TOTAL RETURN FOR PERIODS ENDED 11/30/04 - -------------------------------------------------- Class A (inception 10/23/89) NAV POP - -------------------------------------------------- 6 months 3.57% -1.09% - -------------------------------------------------- 1 year 3.04 -1.58 - -------------------------------------------------- 5 years 31.49 25.53 Annual average 5.63 4.65 - -------------------------------------------------- 10 years 79.19 71.12 Annual average 6.01 5.52 - -------------------------------------------------- Annual average (life of fund) 6.03 5.70 - -------------------------------------------------- Data is historical. Past performance does not guarantee future results. More recent returns may be less or more than those shown. Investment return and principal value will fluctuate and you may have a gain or a loss when you sell your shares. Performance assumes reinvestment of distributions and does not account for taxes. Returns at NAV do not reflect a sales charge of 4.50%. For the most recent month-end performance, visit www.putnaminvestments.com. For a portion of the period, this fund limited expenses, without which returns would have been lower. A 2% short-term trading fee may be applied to shares exchanged or sold within 5 days of purchase. Performance commentary During the six months ended November 30, 2004, despite uncertainty about the war in Iraq and the political landscape at home, the economy was on relatively solid ground and continuing to improve. The fixed-income market generally fared well in this environment. There was a flattening of the yield curve as short-term interest rates rose slightly and rates on longer-term bonds declined. This drove prices on medium- to long-term bonds higher. However, because we had positioned your fund's portfolio defensively in anticipation of a broader-based increase in rates, the fund did not benefit fully from these higher prices. The fund's underperformance of its benchmark index is due in part to this defensive strategy, but also to the fact that the benchmark is nationally diversified and will therefore reflect the strength of other states' municipal bond markets. The fund's returns at net asset value (NAV) were in line with the average for its Lipper category. FUND PROFILE Putnam Michigan Tax Exempt Income Fund seeks to provide as high a level of current income free from federal and state of Michigan personal income taxes, as is believed to be consistent with the preservation of capital. It may be suitable for Michigan investors seeking tax-free income through a diversified portfolio primarily consisting of Michigan municipal bonds. Market overview Over the past six months, most municipal yields fell and bond prices, which move in the opposite direction of yields, rose. Early 2004 was marked by rising yields, as bond market investors were anticipating that the Federal Reserve Board (the Fed) would need to raise short-term interest rates. Interestingly, when the Fed announced what had been a widely anticipated 25-basis-point (one quarter of a percentage point) increase at its June 30 meeting, the bond market changed course. Yields of municipal bonds with maturities greater than two years generally trended downward. At the same time, yields rose for bonds with very short maturities (two years and shorter). This resulted in a flattening of the yield curve -- that is, shorter- and longer-term interest rates began to converge. Among uninsured bonds and bonds rated A and below, yield spreads generally tightened and bond prices rose. These higher-yielding securities continued to provide attractive income streams that also contributed to the fund's total return. Municipal bonds issued by the State of California were generally strong performers, as the economy improved and rating agencies upgraded the state's credit rating. Yields on tobacco settlement bonds varied with the results of ongoing legal battles, but declined overall for the period and their prices rose, accordingly. Airline-related industrial development bonds (IDBs) performed poorly, in general, as the industry continued to face financial difficulties that were made worse by record high oil prices. New York City general obligation bonds rose in price over the past six months, reflecting a dearth of new issuance, as well as investors' confidence in improving economic prospects for the city. - ------------------------------------------------------------------------------- MARKET SECTOR PERFORMANCE 6 MONTHS ENDED 11/30/04 - ------------------------------------------------------------------------------- Bonds - ------------------------------------------------------------------------------- Lehman Municipal Bond Index (tax-exempt bonds) 4.29% - ------------------------------------------------------------------------------- Lehman Aggregate Bond Index (broad bond market) 3.82% - ------------------------------------------------------------------------------- Lehman Intermediate Government Bond Index (intermediate-maturity U.S. government bonds) 2.19% - ------------------------------------------------------------------------------- JP Morgan Global High Yield Index (global high-yield corporate bonds) 9.02% - ------------------------------------------------------------------------------- Equities - ------------------------------------------------------------------------------- S&P 500 Index (broad stock market) 5.68% - ------------------------------------------------------------------------------- Russell 2000 Index (stocks of small and midsize companies) 12.18% - ------------------------------------------------------------------------------- MSCI EAFE Index (international stocks) 12.58% - ------------------------------------------------------------------------------- These indexes provide an overview of performance in different market sectors for the six months ended 11/30/04. - ------------------------------------------------------------------------------- Strategy overview We believe that interest rates will likely rise and we are positioning the portfolio more defensively. This involves shortening the fund's duration, which means reducing its sensitivity to changes in interest rates. Because we believe the yield curve will likely continue to flatten, we have concentrated our bond sales in shorter and intermediate maturities, which we believe are likely to underperform. We also used interest-rate swaps to manage the fund's duration. Meanwhile, we continued to trim and diversify the fund's positions in uninsured bonds and bonds rated A and below, which have performed strongly. The fund maintained an overweight position in tobacco settlement bonds relative to its benchmark. We closely monitored developments in this sector. In previous fiscal years, the fund emphasized non-callable bonds -- bonds that the issuer is not permitted to redeem (or call) before the maturity date. These issues performed well as rates fell through March 2004, but during the spring we began to moderate this position, selling non-callable bonds and purchasing longer callable issues. We believe these callable bonds may perform better than non-callable bonds if interest rates rise and the yield curve flattens further. [GRAPHIC OMITTED: horizontal bar chart THE FUND'S MATURITY AND DURATION COMPARED] THE FUND'S MATURITY AND DURATION COMPARED 5/31/04 11/30/04 Average effective maturity in years 7.6 6.2 Duration in years 5.4 4.6 Footnotes read: This chart compares changes in the fund's duration (a measure of its sensitivity to interest-rate changes) and its average effective maturity (a weighted average of the holdings' maturities). Average effective maturity also takes into account put and call features, where applicable, and reflects prepayments for mortgage-backed securities. How fund holdings affected performance Tobacco settlement bonds continued to perform well for the fund. These bonds are secured by the income stream from tobacco companies' settlement obligations to the states and generally offer higher yields than bonds of comparable quality. This income could be jeopardized as a result of multibillion-dollar judgments against the tobacco companies, and prices in this sector have shifted as concerns about litigation overshadowed optimism. These bonds had generated mixed returns during the period, but as credit spreads -- the difference in yields between higher-quality and lower-quality bonds -- continued to narrow late in the reporting period, tobacco settlement bonds saw a meaningful uptick. We expect a certain degree of continued volatility from these holdings, but on the whole, we find them an attractive investment opportunity and remain slightly overweighted in this sector, relative to the benchmark index. While these holdings performed well, due to the size of our positions, they had a limited impact on the performance of the portfolio. Also of significance were the returns generated by your fund's other lower-quality positions. As yields on lower-rated bonds fell during the period, prices on older issues tended to rise. This trend was not surprising, and to that end, we tried to capitalize on narrowing spreads by selling into investor demand for yield. One specific example of a lower-rated bond that performed well is Flint Hospital Building Authority revenue bonds for Hurley Medical Center, which has a maturity date of 2020. Bonds from the state's hospital and health-care sectors performed well for the fund, and this particular issue was among the stronger performers over the period. In an effort to further diversify the fund's holdings and because hospitals are generally under a certain degree of pressure from rising labor costs, we sold off some of the fund's position in Pontiac Hospital Financing Authority for North Oakland Medical Center bonds. While this holding had performed well, we felt there were other, more attractive opportunities in the market, especially among callable bonds. [GRAPHIC OMITTED: pie chart CREDIT QUALITY OVERVIEW] CREDIT QUALITY OVERVIEW AAA (69.0%) Aa (6.2%) A (8.2%) Baa (7.0%) Ba (3.4%) B (1.9%) VMIG1 (4.3%) Footnote reads: As a percentage of market value as of 11/30/04. A bond rated Baa or higher is considered investment grade. The chart reflects Moody's ratings; percentages may include bonds not rated by Moody's but considered by Putnam Management to be of comparable quality. Ratings will vary over time. For the last few years, the fund has maintained a position in non-callable bonds -- bonds that cannot be refunded by the issuer before the maturity date. In a declining interest-rate environment, the fixed-income market tends to put a premium on this feature. With interest rates rising, that added layer of protection is less useful and we believe these bonds are becoming less attractive. With that in mind, we sold non-callable securities like Michigan Public Power Refunding bonds and purchased callable bonds such as Gull Lake School District bonds, which are callable in 2014. This type of move was beneficial from a relative value standpoint, since we believe callable bonds are likely to outperform their non-callable counterparts going forward. 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 outlook for your fund The following commentary reflects anticipated developments that could affect your fund over the next six months, as well as your management team's plans for responding to them. Judging from the flattened yield curve, the bond market appears to have largely shrugged off the recent Fed rate hikes. However, we believe that interest rates all along the yield curve are more likely to rise than fall. The Fed has raised the fed funds rate four times in 25-basis-point increments since June 2004, bringing it to two percent at the end of the period. We believe the Fed will likely continue to raise short-term rates incrementally through mid-2005, which is likely to cause rising yields among bonds with shorter maturities. This also suggests possible further flattening of the yield curve. The fund is positioned defensively in terms of duration, and we will continue to monitor and adjust the fund's duration as it seems appropriate. We believe inflation will likely remain low, despite the threat posed by high oil prices. We also anticipate that the rate of GDP growth may slow during the next two quarters, as the effects of the Fed's tightening policy are felt. In general, these signs indicate that we are headed into a potentially more challenging environment for bond investing. Our task will be to continue to search for the most attractive opportunities among tax-exempt securities and to balance the pursuit of attractive current income with prudent risk management. The views expressed in this report are exclusively those of Putnam Management. They are not meant as investment advice. This fund concentrates its investments in one state and involves more risk than a fund that invests more broadly. Capital gains, if any, are taxable for federal and, in most cases, state purposes. For some investors, investment income may be subject to the federal alternative minimum tax. Income from federally exempt funds may be subject to state and local taxes. Mutual funds that invest in bonds are subject to certain risks, including interest-rate risk, credit risk, and inflation risk. As interest rates rise, the prices of bonds fall. Long-term bonds are more exposed to interest-rate risk than short-term bonds. Unlike bonds, bond funds have ongoing fees and expenses. Tax-free funds may not be suitable for IRAs and other non-taxable accounts. Your fund's management Your fund is managed by the members of the Putnam Tax Exempt Fixed-Income Team.

In the most recent six-month period, your fund limited these expenses; had it not done so, expenses would have been higher. Using the information below, you can estimate how these expenses affect your investment and compare them with the expenses of other funds. You may also pay one-time transaction expenses, including sales charges (loads) and redemption fees, which are not shown in this section and would have resulted in higher total expenses. For more information, see your fund's prospectus or talk to your financial advisor. Review your fund's expenses The table below shows the expenses you would have paid on a $1,000 investment in Putnam Michigan Tax Exempt Income Fund from June 1, 2004, to November 30, 2004. It also shows how much a $1,000 investment would be worth at the close of the period, assuming actual returns and expenses. - ------------------------------------------------------------------------------- EXPENSES AND VALUE OF A $1,000 INVESTMENT assuming actual returns for the 6 months ended 11/30/04 - ------------------------------------------------------------------------------- Class A Class B Class M - ------------------------------------------------------------------------------- Expenses paid per $1,000* $4.64 $7.95 $6.17 - ------------------------------------------------------------------------------- Ending value (after expenses) $1,035.70 $1,032.30 $1,034.10 - ------------------------------------------------------------------------------- * Expenses for each share class are calculated using the fund's annualized expense ratio for each class, which represents the ongoing expenses as a percentage of net assets for the six months ended 11/30/04.

Expenses are calculated by multiplying the expense ratio by the average account value for the period; then multiplying the result by the number of days in the period; and then dividing that result by the number of days in the year. Using industry averages to compare expenses You can also compare your fund's expenses with industry averages, as determined by Lipper, an independent fund-rating agency that ranks funds relative to others that Lipper considers to have similar investment styles or objectives. The expense ratio for each share class shown below indicates how much of your fund's net assets have been used to pay ongoing expenses during the period. - ----------------------------------------------------------------------------- EXPENSE RATIO COMPARISONS USING ANNUALIZED DATA - ----------------------------------------------------------------------------- Class A Class B Class M - ----------------------------------------------------------------------------- Your fund's annualized expense ratio 0.91% 1.56% 1.21% - ----------------------------------------------------------------------------- Average annualized expense ratio for Lipper peer group+ 0.95% 1.60% 1.25% - ----------------------------------------------------------------------------- + Average of the expenses of front-end load funds viewed by Lipper as having the same investment classification or objective as the fund, as of 9/30/04, calculated in accordance with Lipper's standard reporting methodology for comparing expenses within a given universe (excluding 12b-1 fees and without giving effect to any expense offset and brokerage service arrangements that may reduce fund expenses). To facilitate comparison, Putnam has adjusted this average to reflect the 12b-1 fees carried by each class of shares. The peer group may include funds that are significantly larger or smaller than the fund, which may limit the comparability of the fund's expenses to the Lipper average. Understanding your fund's portfolio turnover Putnam funds are actively managed by teams of experts who buy and sell securities based on intensive analysis of companies, industries, economies, and markets. Portfolio turnover is a measure of how often a fund's managers buy and sell securities for your fund. A portfolio turnover of 100%, for example, means that the managers sold and replaced securities valued at 100% of a fund's assets within a one-year period. Funds with high turnover may be more likely to generate capital gains and dividends that must be distributed to shareholders as taxable income. High turnover may also cause a fund to pay more brokerage commissions and other transaction costs, which may detract from performance. Funds that invest in bonds may have higher turnover than funds that invest only in stocks. Short-term bond funds tend to have higher turnover than longer-term bond funds, because shorter-term bonds will mature or be sold more frequently than longer-term bonds. You can use the table below to compare your fund's turnover with the average turnover for funds in its Lipper category. - ----------------------------------------------------------------------------- TURNOVER COMPARISONS percentage of holdings that change every year - ----------------------------------------------------------------------------- 2004 2003 2002 2001 2000 - ----------------------------------------------------------------------------- Putnam Michigan Tax Exempt Income Fund 10% 24% 21% 14% 7% - ----------------------------------------------------------------------------- Lipper Michigan Municipal Debt Funds category average 26% 30% 20% 29% 47% - ----------------------------------------------------------------------------- Turnover data for the fund is calculated based on the fund's fiscal-year period, which ends on May 31. Turnover data for the fund's Lipper category is calculated based on the average of the turnover of each fund in the category for its fiscal year ended during the indicated year. Fiscal years vary across funds in the Lipper category, which may limit the comparability of the fund's portfolio turnover rate to the Lipper average. Comparative data for 2004 is based on information available as of 9/30/04. Risk comparison As part of new initiatives to enhance disclosure, we are including a risk comparison to help you understand how your fund compares with other funds. The comparison utilizes a risk measure developed by Morningstar, an independent fund-rating agency. This risk measure is referred to as the fund's Overall Morningstar Risk. [GRAPHIC OMITTED: chart MORNINGSTAR [REGISTRATION MARK] RISK] MORNINGSTAR [REGISTRATION MARK] RISK Fund's Overall Morningstar Risk 0.16 Municipal bond fund average 0.21 0% INCREASING RISK 100% Your fund's Overall Morningstar Risk is shown alongside that of the average fund in its broad asset class, as determined by Morningstar. The risk bar broadens the com par ison by translating the fund's Overall Morningstar Risk into a percentile, which is based on the fund's ranking among all funds rated by Morningstar as of December 31, 2004. A higher Overall Morningstar Risk generally indicates that a fund's monthly returns have varied more widely. Morningstar determines a fund's Overall Morningstar Risk by assessing variations in the fund's monthly returns -- with an emphasis on downside variations -- over 3-, 5-, and 10-year periods, if available. Those measures are weighted and averaged to produce the fund's Overall Morningstar Risk. The information shown is provided for the fund's class A shares only; information for other classes may vary. Overall Morningstar Risk is based on historical data and does not indicate future results. Morningstar does not purport to measure the risk associated with a current investment in a fund, either on an absolute basis or on a relative basis. Low Overall Morningstar Risk does not mean that you cannot lose money on an investment in a fund. Copyright 2004 Morningstar, Inc. All Rights Reserved.

Terms and definitions Total return shows how the value of the fund's shares changed over time, assum ing you held the shares through the entire period and reinvested all distributions in the fund. Net asset value (NAV) is the price, or value, of one share of a mutual fund, without a sales charge. NAVs fluctuate with market conditions. NAV is calculated by dividing the net assets of each class of shares by the number of outstanding shares in the class. Public offering price (POP) is the price of a mutual fund share plus the maximum sales charge levied at the time of pur chase. POP performance figures shown here assume the 4.50% maximum sales charge for class A shares and 3.25% for class M shares. 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 class B 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. Class A shares are generally subject to an initial sales charge and no sales charge on redemption (except on certain redemptions of shares bought without an initial sales charge). Class B shares may be subject to a sales charge upon redemption. Class M shares have a lower initial sales charge and a higher 12b-1 fee than class A shares and no sales charge on redemption (except on certain redemptions of shares bought without an initial sales charge). Comparative indexes JP Morgan Global High Yield Index is an unmanaged index used to mirror the investable universe of the U.S. dollar global high-yield corporate debt market of both developed and emerging markets. Lehman Aggregate Bond Index is an unmanaged index used as a general measure of U.S. fixed-income securities. Lehman Intermediate Government Bond Index is an unmanaged index of government bonds with maturities between 1 and 10 years. Lehman Municipal Bond Index is an unmanaged index of long-term fixed-rate investment-grade tax-exempt bonds. Morgan Stanley Capital International (MSCI) EAFE Index is an unmanaged index of international stocks from Europe, Australasia, and the Far East. Russell 2000 Index is an unmanaged index of common stocks that generally measure performance of small to midsize companies within the Russell 3000 Index. S&P 500 Index is an unmanaged index of common stock performance. 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. Lipper is a third-party industry ranking entity that ranks funds (without sales charges) with similar current investment styles or objectives as determined by Lipper. Lipper category averages reflect performance trends for funds within a category and are based on results at net asset value. A note about duplicate mailings In response to investors' requests, the SEC has modified mailing regulations for proxy statements, semiannual and annual reports, and prospectuses. Putnam is now able to send a single copy of these materials to customers who share the same address. This change will automatically apply to all shareholders except those who notify us. If you would prefer to receive your own copy, please call Putnam at 1-800-225-1581. Proxy voting Putnam is committed to managing our mutual funds in the best interests of our shareholders. The Putnam funds' proxy voting guidelines and procedures, as well as information regarding how your fund voted proxies relating to portfolio securities during the 12-month period ended June 30, 2004, are available on the Putnam Individual Investor Web site, www.putnaminvestments.com/individual, and on the SEC's Web site, www.sec.gov. If you have questions about finding forms on the SEC's Web site, you may call the SEC at 1-800-SEC-0330. You may also obtain the Putnam funds' proxy voting guidelines and procedures at no charge by calling Putnam's Shareholder Services at 1-800-225-1581. Fund portfolio holdings For periods ending on or after July 9, 2004, the fund will file a complete schedule of its portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. Shareholders may obtain the fund's Forms N-Q on the SEC's Web site at www.sec.gov. In addition, the fund's Forms N-Q may be reviewed and copied at the SEC's public reference room in Washington, D.C. You may call the SEC at 1-800-SEC-0330 for information about the SEC's Web site or the operation of the public reference room. 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 the fund's net investment gain or loss, 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.

The accompanying notes are an integral part of these financial statements. Notes to financial statements November 30, 2004 (Unaudited) Note 1 Significant accounting policies Putnam Michigan Tax Exempt Income Fund (the "fund"), a Massachusetts business trust, 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 exempt from federal income tax and Michigan personal income tax as Putnam Investment Management, LLC ("Putnam Management"), the fund's Manager, an indirect wholly-owned subsidiary of Putnam, LLC, believes is consistent with preservation of capital by investing primarily in a portfolio of investment-grade Michigan tax-exempt securities with intermediate to long-term maturities. The fund may be affected by economic and political developments in the state of Michigan. The fund offers class A, class B and class M shares. Class A shares are sold with a maximum front-end sales charge of 4.50%. Class B shares, which convert to class A shares after approximately eight years, do not pay a front-end sales charge, but pay a higher ongoing distribution fee than class A shares, and are subject to a contingent deferred sales charge, if those shares are redeemed within six years of purchase. Class M shares are sold with a maximum front-end sales charge of 3.25% and pay an ongoing distribution fee that is higher than class A but lower than class B shares. Effective April 19, 2004 (May 3, 2004 for defined contribution plans administered by Putnam) a 2.00% redemption fee may apply to any shares that are redeemed (either by selling or exchanging into another fund) within 5 days of purchase. The redemption fee is accounted for as an addition to paid-in-capital. Investment income, realized and unrealized gains and losses and expenses of the fund are borne pro-rata based on the relative net assets of each class to the total net assets of the fund, except that each class bears expenses unique to that class (including the distribution fees applicable to such classes). Each class 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 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 at fair value 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. Other investments 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) Interest rate swap contracts The fund may enter into interest rate swap contracts, which are arrangements between two parties to exchange cash flows based on a notional principal amount, to manage the fund's exposure to interest rates. Interest rate swap contracts are marked to market daily based upon quotations from market makers and the change, if any, is recorded as unrealized gain or loss. Payments received or made are recorded as realized gains or loss. The fund could be exposed to credit or market risk due to unfavorable changes in the fluctuation of interest rates or if the counterparty defaults on its obligation to perform. Risk of loss may exceed amounts recognized on the statement of assets and liabilities. Interest rate swap contracts outstanding at period end, if any, 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 of 1986 (the "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 Code, 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 May 31, 2004, the fund had a capital loss carryover of $2,703,197 available to the extent allowed by the Code to offset future net capital gain, if any. The amount of the carryover and the expiration dates are: Loss Carryover Expiration - ---------------------------------- $939,071 May 31, 2008 1,546,980 May 31, 2009 217,146 May 31, 2012 Pursuant to federal income tax regulations applicable to regulated investment companies, the fund has elected to defer to its fiscal year ending May 31, 2005 $162,284 of losses recognized during the period November 1, 2003 to May 31, 2004. The aggregate identified cost on a tax basis is $128,154,610, resulting in gross unrealized appreciation and depreciation of $5,213,718 and $1,332,488, respectively, or net unrealized appreciation of $3,881,230. E) Distributions to shareholders Income dividends are recorded daily by the fund and are paid monthly. Distributions from capital gains, if any, are recorded on the ex-dividend date and paid at least annually. 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. 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 lesser of (i) an annual rate of 0.50% of the average net assets of the fund or (ii) the following annual rates expressed as a percentage of the fund's average net assets: 0.60% of the first $500 million, 0.50% of the next $500 million, 0.45% of the next $500 million, 0.40% of the next $5 billion, 0.375% of the next $5 billion, 0.355% of then next $5 billion, 0.34% of the next $5 billion and 0.33% thereafter. Effective January 28, 2004, Putnam Management has agreed to waive fees and reimburse expenses of the fund through May 31, 2005 to the extent necessary to ensure that the fund's expenses do not exceed the average expenses of the front-end load funds viewed by Lipper Inc. as having the same investment classification or objective as the fund. The expense reimbursement is based on a comparison of the fund's expenses with the average annualized operating expenses of the funds in its Lipper peer group for each calendar quarter during the fund's last fiscal year, excluding 12b-1 fees and without giving effect to any expense offset and brokerage service arrangements that may reduce fund expenses. For the period ended November 30, 2004, Putnam Management waived $17,489 of its management fee from the fund. For the period ended November 30, 2004, Putnam Management has assumed $2,510 of legal, shareholder servicing and communication, audit and Trustee fees incurred by the fund in connection with certain legal and regulatory matters, (including those described in Note 5). 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 subsidiary of Putnam, LLC. Putnam Investor Services, a division of PFTC, provides investor servicing agent functions to the fund. During the six months ended November 30, 2004, the fund paid PFTC $99,142 for these services. 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 November 30, 2004, the fund's expenses were reduced by $9,120 under these arrangements. Each independent Trustee of the fund receives an annual Trustee fee, of which $635, as a quarterly retainer, 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 Trustee compensation and expenses in the statement of operations. Accrued pension liability is included in Payable for Trustee compensation and expenses in the statement of assets and liabilities. The Trustees have terminated the Pension Plan with respect to any Trustee first elected after 2003. The fund has adopted distribution plans (the "Plans") with respect to its class A, class B and class M shares pursuant to rule 12b-1 under the Investment Company Act of 1940. The purpose of the Plans is to compensate Putnam Retail Management, a wholly-owned subsidiary of Putnam, LLC and Putnam Retail Management GP, Inc., for services provided and expenses incurred in distributing shares of the fund. The Plans provide for payments by the fund to Putnam Retail Management at annual rates of up to 0.35%, 1.00% and 1.00% of the average net assets attributable to class A, class B and class M shares, respectively. The Trustees have approved payment by the fund at the annual rates of 0.20%, 0.85% and 0.50% of the average net assets attributable to class A, class B and class M shares, respectively. For the six months ended November 30, 2004, Putnam Retail Management, acting as underwriter, received net commissions of $76 and $11 from the sale of class A and class M shares, respectively, and $28,357 in contingent deferred sales charges from redemptions of class B shares. A deferred sales charge of up to 1.00% is assessed on certain redemptions of class A shares that were purchased without an initial sales charge as part of an investment of $1 million or more. For the six months ended November 30, 2004, Putnam Retail Management, acting as underwriter, received no monies on class A redemptions.

The settlement with the SEC requires Putnam Management to pay $5 million in disgorgement plus a civil monetary penalty of $50 million, and the settlement with the Massachusetts Securities Division requires Putnam Management to pay $5 million in restitution and an administrative fine of $50 million. The settlements also leave intact the process established under an earlier partial settlement with the SEC under which Putnam Management agreed to pay the amount of restitution determined by an independent consultant, which may exceed the disgorgement and restitution amounts specified above, pursuant to a plan to be developed by the independent consultant. Putnam Management, and not the investors in any Putnam fund, will bear all costs, including restitution, civil penalties and associated legal fees stemming from both of these proceedings. The SEC's and Massachusetts Securities Division's allegations and related matters also serve as the general basis for numerous lawsuits, including purported class action lawsuits filed against Putnam Management and certain related parties, including certain Putnam funds. Putnam Management has agreed to bear any costs incurred by Putnam funds in connection with these lawsuits. Based on currently available information, Putnam Management believes that the likelihood that the pending private lawsuits and purported class action lawsuits will have a material adverse financial impact on the fund is remote, and the pending actions are not likely to materially affect its ability to provide investment management services to its clients, including the Putnam funds. The fund may experience increased redemptions as a result of these matters, which could result in increased transaction costs and operating expenses.
