Putnam U.S. Government 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: ANNUAL REPORT ON PERFORMANCE AND OUTLOOK 9-30-04 [GRAPHIC OMITTED: BASEBALL CARD] [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 introduced a number of reforms for the benefit of shareholders, including increasing the amount of disclosure for our funds. Beginning with this month's reports, we inform you of any change during the prior year of the Portfolio Leader and Portfolio Members of your fund's management team. Additionally, we list the other fund management responsibilities of your fund's Portfolio Leader and Portfolio Members. This new information, which you can find following the Outlook for Your Fund, complements the expense, risk, and portfolio turnover comparisons we added to the reports earlier this year. We are also pleased to announce that three new Trustees have joined your fund's Board of Trustees. Nominated by the 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 U.S. Government Income Trust delivered respectable results. In the following pages, the fund managers discuss fund performance, strategy, and their outlook for fiscal 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 November 17, 2004 Report from Fund Management Fund highlights * For the 12 months ended September 30, 2004, Putnam U.S. Government Income Trust's class A shares returned 2.81% without sales charges and -2.09% with maximum sales charges reflected. * The fund's benchmark, the Lehman GNMA Index, returned 4.16%. * The average return for the fund's Lipper category, GNMA Funds, was 2.82%. * The fund's dividend was increased to $0.034 per share in July 2004. See page 5 for details. * See the Performance Summary beginning on page 8 for additional fund performance, comparative performance, and Lipper data. Performance commentary Over the course of the year ended September 30, 2004, market sentiment about the direction of interest rates shifted several times, making it a challenging period for fixed-income investors. In this environment, we maintained a modestly defensive portfolio structure for Putnam U.S. Government Income Trust. Although this strategy detracted from results when rates trended lower, it proved more beneficial when rates rose. While our emphasis on the strong-performing mortgage-backed securities (MBS) sector was at the high end of our target range during the period, the portfolio also held Treasuries and agencies -- sectors that lagged MBSs. This explains the fund's underperformance versus its primary benchmark, the Lehman GNMA Index, which is made up entirely of MBSs. The fund performed in line with its Lipper peer group, based on results at net asset value (NAV).

FUND PROFILE Putnam U.S. Government Income Trust seeks current income by investing in obligations of the U.S. government and its agencies and instrumentalities, such as Government National Mortgage Association certificates (Ginnie Maes), Federal National Mortgage Association certificates (Fannie Maes), Federal Home Loan Mortgage Corporation certificates (Freddie Macs), and U.S. Treasury securities. Ginnie Maes, Fannie Maes, and Freddie Macs are generally high quality and can provide higher yields than Treasury securities of similar maturities. The fund is designed primarily for investors seeking income, but it can also lower volatility in a well-diversified portfolio. Market overview Conflicting signals about the strength of U.S. economic growth drove bond market performance during the year. While some signs pointed to expansion -- a strong housing market, reports of solid corporate profits, and respectable GDP growth -- others, such as disappointing job growth and low capacity utilization, did not support perceptions of economic growth. Bond investors watch these signals closely as they can indicate the likely direction of interest rates, which is determined by both Federal Reserve Board (Fed) policy and by the sentiment of market participants. Bond prices move inversely with interest rates, declining when rates rise and increasing when rates fall. Interest rates meandered up and down in response to contrasting economic signals until April 2004 when investors aggressively bid up rates because they believed that the Fed would need to significantly raise short-term interest rates to reign in growth. The Fed's approach proved more gradualist, however, as it raised rates three times in the final months of the period in modest 0.25% increments. Signs of more modest growth supported this approach and worked with it to lower bond market volatility. Yields on securities with shorter maturities rose significantly while yields at the long end of the maturity spectrum remained fairly stable, resulting in a flattening in the shape of the yield curve. Lower volatility, which resulted from clear guidance on the direction of interest rates from the Fed, created a favorable environment for MBSs, enabling them to outperform Treasuries and agencies, the other sectors in which your fund can invest. Prices of MBSs also benefited from increased investor demand worldwide, as their higher yields, and generally high credit quality, proved especially attractive in a low-rate environment. - ------------------------------------------------------------------------------- MARKET SECTOR PERFORMANCE 12 MONTHS ENDED 9/30/04 - ------------------------------------------------------------------------------- Bonds - ------------------------------------------------------------------------------- Lehman GNMA Index (Government National Mortgage Association bonds) 4.16% - ------------------------------------------------------------------------------- Lehman Aggregate Bond Index (broad bond market) 3.68% - ------------------------------------------------------------------------------- Lehman Municipal Bond Index (tax-exempt bonds) 4.59% - ------------------------------------------------------------------------------- JP Morgan Global High Yield Index (global high-yield corporate bonds) 13.13% - ------------------------------------------------------------------------------- Equities - ------------------------------------------------------------------------------- S&P 500 Index (broad stock market) 13.87% - ------------------------------------------------------------------------------- Russell 1000 Growth Index (large-company growth stocks) 7.51% - ------------------------------------------------------------------------------- Russell 1000 Value Index (large-company value stocks) 20.52% - ------------------------------------------------------------------------------- These indexes provide an overview of performance in different market sectors for the 12 months ended 9/30/04. - ------------------------------------------------------------------------------- Strategy overview There are six key strategy decisions that we make in managing the fund. The first is called term structure and reflects our views of the direction of interest rates based on factors such as economic indicators, Fed statements and strategy, and market sentiment. We also analyze the shape of the yield curve and strive to position your fund's portfolio to benefit from expected movements. Our second strategic decision involves sector allocation. We seek to determine the relative attractiveness among the sectors in which your fund can invest -- Treasuries, agencies, and MBSs -- and then position your fund's portfolio to take advantage of our sector preferences. We also weigh the relative attractiveness among the various programs in the MBS market: Government National Mortgage Association certificates (Ginnie Maes), Federal National Mortgage Association certificates (Fannie Maes), and Federal Home Loan Mortgage Corporation certificates (Freddie Macs). We make three other strategic decisions related to MBSs: We seek to determine what maturity is most attractive (e.g., 30-year, 15-year, or adjustable-rate); we assess what coupon level (e.g., 5.5%, 6.5%, 7%, etc.) or what combination of coupons provides the best risk/return trade off. Seasoning is our fifth consideration, as mortgages with the same coupon level may vary in issue date and an older or more "seasoned" mortgage is typically less likely to be prepaid. Our sixth strategic decision concerns out-of-benchmark exposure; we consider the relative attractiveness of securities that are not in your primary benchmark, but are allowable within your fund's guidelines. [GRAPHIC OMITTED: horizontal bar chart THE FUND'S MATURITY AND DURATION COMPARED] THE FUND'S MATURITY AND DURATION COMPARED 9/30/03 3/31/04 9/30/04 Average effective maturity in years 3.4 3.6 5.2 Duration in years 1.9 2.1 2.2 Footnote reads: 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 sector allocations and fund holdings affected performance With rates at historic lows and key indicators pointing toward faster economic growth, we believed that the most likely direction for interest rates was higher. Therefore, the portfolio's duration, which is a measure of interest-rate sensitivity, was kept modestly shorter, or defensive, in comparison to its benchmark through most of the period. This aspect of our term-structure decision proved detrimental to performance as interest rates defied expectations and generally declined through mid-period. Regarding the shape of the yield curve, it was our expectation that short-term rates would rise more quickly than long-term rates, resulting in yield-curve flattening. This proved true and your fund's portfolio was positioned to benefit from the shift. Generally, our sector allocation strategy had a positive impact on performance. Believing that mortgage-backed securities (MBSs) were attractive on a relative basis, we emphasized this sector over agency and Treasury securities -- the other sectors in which your fund invests. The fund benefited from this strategy on an absolute basis. Among the various programs within the MBS market, our strategy included exposure to securities issued by the Federal National Mortgage Association (Fannie Maes) and the Federal Home Loan Mortgage Corporation (Freddie Macs) as well as a significant position in the standard pass-through securities issued by the Government National Mortgage Association (Ginnie Maes), as our valuation analysis showed that investors were being well rewarded with higher yields for the marginal additional risks posed by Fannie- and Freddie-issued securities. Fannie Mae and Freddie Mac are not represented in your fund's benchmark so these allocations represent an out-of-benchmark exposure. Our program strategy detracted from results as Ginnie Maes marginally outperformed securities issued by the other programs based on strong overseas demand from Asia. Ginnie Maes were attractive to overseas investors as they are backed by the full faith and credit of the U.S. government, while the other MBSs are backed only by the credit of the issuing agency. [GRAPHIC OMITTED: horizontal bar chart PORTFOLIO COMPOSITION AS OF 9/30/04] PORTFOLIO COMPOSITION AS OF 9/30/04 Ginnie Mae Fannie Mae Freddie Mac U.S. government and agency obligations 71.8% 9.9% 1.9% Short-term investments 20.4% Collateralized mortgage obligations 8.9% Footnote reads: Weightings are shown as a percentage of net assets. Holdings will vary over time. A portion of short-term investments reflects amounts used to settle TBA purchase commitments. Our strategy of emphasizing higher-coupon MBSs was rewarded during the period, as this market segment outperformed. Likewise, our decision to favor seasoned or older mortgages also worked to the fund's advantage as these securities proved less subject to prepayments. Our maturity decision -- an emphasis on 30-year maturities -- also contributed to relative results. Regarding other out-of-benchmark exposures, the fund continued to hold a type of collateralized mortgage obligation (CMO) known as interest-only strips. These are high-quality investments that typically offer slightly higher yields than conventional mortgage-backed securities in exchange for increased sensitivity to prepayments. We believe that the market is currently offering a greater yield on these securities than is warranted by the prepayment risk. In addition, late in the period we took advantage of what we believed were attractive prices to initiate a position in adjustable-rate mortgages (ARMs). 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. OF SPECIAL INTEREST Your fund's dividend depends on yields available on the types of fixed-income securities in which your fund invests. Modestly rising yields on Treasury and mortgage-backed securities resulted in a dividend increase from $0.028 to $0.034 per share for class A shares in July 2004. 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. We believe that interest rates will continue to rise as the Fed seeks to manage the pace of economic growth with steady, modest rate increases and as rates continue to rebound from abnormally low levels. Therefore, your portfolio remains conservatively positioned with a modestly short duration in an effort to protect principal value. We have moved to a more neutral stance with regard to yield curve positioning because, although we expect the curve to continue to flatten, we believe that the market has already anticipated much of this flattening. Given the strong performance recorded by MBSs over the past year, we believe they are currently overpriced. Therefore, we have reduced the fund's MBSs exposure in favor of short-term fixed income securities. Within the MBS sector, we continue to favor Fannie Maes and Freddie Macs over Ginnie Maes, because we believe that investors are being well compensated for the slight additional risks they carry. We also think that many investors have overreacted to the negative headlines about the management of these programs. In addition, the market for Fannie Maes is much larger and more liquid than either the market for Ginnie Maes or Freddie Macs, offering greater flexibility in trading and more opportunities in coupons and seasoning. We believe that the more tools we have at our disposal, the more opportunities we have to add value. We currently favor higher-coupon issues as we believe the market is currently overcompensating investors for the higher prepayment risk posed by these securities. Where available, we are also seeking out more seasoned issues. We will continue to employ our multi-step strategy in pursuit of high current income that is also consistent with preservation of capital. The views expressed in this report are exclusively those of Putnam Management. They are not meant as investment advice. 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. Mutual funds that invest in government securities are not guaranteed. Mortgage-backed securities are subject to prepayment risk.

Understanding your fund's expenses As a mutual fund investor, you pay ongoing expenses, such as management fees, distribution fees (12b-1 fees), and other expenses. 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 U.S. Government Income Trust from April 1, 2004, to September 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.

Per these guidelines, the table below shows your fund's expenses based on a $1,000 investment, assuming a hypothetical 5% annualized return. You can use this information to compare the ongoing expenses (but not transaction expenses or total costs) of investing in the fund with those of other funds. All mutual fund shareholder reports will provide this information to help you make this comparison. Please note that you cannot use this information to estimate your actual ending account balance and expenses paid during the period.

The expense ratio may differ for each share class (see the table at the bottom of this page). 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.

All Lipper data is for the most recent fiscal periods available as of 9/30/04. For class B, C, M and R shares, Putnam has adjusted the Lipper total expense average to reflect higher 12b-1 fees incurred by these classes 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 U.S. Government Income Trust 198% 332% 277% 157% 133% - ------------------------------------------------------------------------------ Lipper GNMA Funds Average 313% 286% 257% 221% 209% - ------------------------------------------------------------------------------ Turnover data for the fund is calculated based on the fund's fiscal-year period, which ends on September 30. 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 compatibility 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 0.07 Taxable bond fund average 0.31 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 comparison 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 September 30, 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, assuming 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 purchase. POP performance figures shown here assume the 4.75% maximum sales charge for class A shares (since reduced to 4.50%) 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 or C 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. The CDSC for class C shares is 1% for one year after purchase. 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 C shares are not subject to an initial sales charge and are subject to a contingent deferred sales charge only if the shares are redeemed during the first year. 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). Class R shares are not subject to an initial sales charge or CDSC and are available only to certain defined contribution plans. 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 GNMA Index is an unmanaged index of Government National Mortgage Association bonds. Lehman Municipal Bond Index is an unmanaged index of long-term fixed-rate investment-grade tax-exempt bonds. Russell 1000 Growth Index is an unmanaged index of those companies in the Russell 1000 Index chosen for their growth orientation. Russell 1000 Value Index is an unmanaged index of those companies in the Russell 1000 Index chosen for their value orientation. 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.

We may also share this information with our Putnam affiliates to service your account or provide you with information about other Putnam products or services.

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.

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, preceded by the Report of Independent Registered Public Accounting Firm, 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 year. 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. Report of Independent Registered Public Accounting Firm The Board of Trustees and Shareholders Putnam U.S. Government Income Trust: We have audited the accompanying statement of assets and liabilities of Putnam U.S. Government Income Trust, including the fund's portfolio, as of September 30, 2004, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended and the financial highlights for each of the periods presented. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform our audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of September 30, 2004 by correspondence with the custodian and brokers or by other appropriate auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Putnam U.S. Government Income Trust as of September 30, 2004, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented, in conformity with U.S. generally accepted accounting principles.

The accompanying notes are an integral part of these financial statements. Notes to financial statements September 30, 2004 Note 1 Significant accounting policies Putnam U.S. Government Income Trust (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's investment objective is to seek as high a level of current income as is consistent with preservation of capital by investing mainly in securities which have short to long-term maturities and are backed by the full faith and credit of the United States. The fund also invests in repurchase agreements and forward commitments relating to those investments. The fund offers class A, class B, class C, class M, class R and class Y shares. Class A shares are sold with a maximum front-end sales charge of 4.50%. Prior to January 28, 2004, the maximum front-end sales charge for class A shares was 4.75%. 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, class M and class R shares, and are subject to a contingent deferred sales charge, if those shares are redeemed within eight years of purchase. Class C shares are subject to the same fees and expenses as class B shares, except that class C shares have a one-year 1.00% contingent deferred sales charge and do not convert to class A shares. 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 shares but lower than class B and class C shares. Class R shares are sold without a front-end sales charge and pay an ongoing distribution fee that is higher than class A shares, but lower than class B and class C shares. Class R shares are offered to qualified employee-benefit plans. Class Y shares, which are sold at net asset value, are generally subject to the same expenses as class A, class B, class C, class M and class R shares, but do not bear a distribution fee. Class Y shares are sold to certain eligible purchasers including certain defined contribution plans (including corporate IRAs), bank trust departments and trust companies. Effective April 19, 2004 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 Investments, including mortgage backed securities, are valued at fair value on the basis of valuations provided by an independent pricing service, approved by the Trustees. Such service providers 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. Short-term investments having remaining maturities of 60 days or less are valued at amortized cost, which approximates fair value. B) Joint trading account The fund may transfer uninvested cash balances, including cash collateral received under security lending arrangements, into a joint trading account along with the cash of other registered investment companies and certain other accounts managed by Putnam Investment Management, LLC ("Putnam Management"), the fund's manager, an indirect wholly-owned subsidiary of Putnam, LLC. These balances may be invested in issuers of high-grade short-term investments having maturities of up to 397 days for collateral received under security lending arrangements and up to 90 days for other cash investments. C) Repurchase agreements The fund, or any joint trading account, through its custodian, receives delivery of the underlying securities, the market value of which at the time of purchase is required to be in an amount at least equal to the resale price, including accrued interest. Collateral for certain tri-party repurchase agreements is held at the counterparty's custodian in a segregated account for the benefit of the fund and the counterparty. Putnam Management is responsible for determining that the value of these underlying securities is at all times at least equal to the resale price, including accrued interest. D) 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. E) TBA purchase commitments The fund may enter into "TBA" (to be announced) commitments to purchase securities for a fixed unit price at a future date beyond customary settlement time. Although the unit price has been established, the principal value has not been finalized. However, the amount of the commitments will not significantly differ from the principal amount. The fund holds, and maintains until settlement date, cash or high-grade debt obligations in an amount sufficient to meet the purchase price, or the fund may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities themselves, and involve a risk of loss if the value of the security to be purchased declines prior to the settlement date, which risk is in addition to the risk of decline in the value of the fund's other assets. Unsettled TBA purchase commitments are valued at fair value of the underlying securities, according to the procedures described under "Security valuation" above. The contract is "marked-to-market" daily and the change in market value is recorded by the fund as an unrealized gain or loss. Although the fund will generally enter into TBA purchase commitments with the intention of acquiring securities for its portfolio or for delivery pursuant to options contracts it has entered into, the fund may dispose of a commitment prior to settlement if Putnam Management deems it appropriate to do so. F) TBA sale commitments The fund may enter into TBA sale commitments to hedge its portfolio positions or to sell mortgage-backed securities it owns under delayed delivery arrangements. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, equivalent deliverable securities or an offsetting TBA purchase commitment deliverable on or before the sale commitment date, are held as "cover" for the transaction. Unsettled TBA sale commitments are valued at fair value of the underlying securities, generally according to the procedures described under "Security valuation" above. The contract is "marked-to-market" daily and the change in market value is recorded by the fund as an unrealized gain or loss. If the TBA sale commitment is closed through the acquisition of an offsetting purchase commitment, the fund realizes a gain or loss. If the fund delivers securities under the commitment, the fund realizes a gain or a loss from the sale of the securities based upon the unit price established at the date the commitment was entered into. TBA sale commitments outstanding at period end, if any, are listed after the fund's portfolio. G) Federal taxes It is the policy of the fund to distribute all of its taxable 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 September 30, 2004, the fund had a capital loss carryover of $63,668,213 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 - ----------------------------------- $8,892,718 September 30, 2005 23,731,356 September 30, 2008 31,044,139 September 30, 2009 H) Distributions to shareholders Distributions to 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. 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. These differences include temporary and permanent differences of losses on wash sales transactions and the expiration of a capital loss carryover. 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. For the year ended September 30, 2004, the fund reclassified $42,025,303 to decrease paid-in-capital, with a decrease to accumulated net realized losses of $42,025,303. The tax basis components of distributable earnings and the federal tax cost as of period end were as follows: Unrealized appreciation $34,943,401 Unrealized depreciation (8,735,810) ------------ Net unrealized appreciation 26,207,591 Undistributed ordinary income 17,470,854 Capital loss carryforward (63,668,213) Cost for federal income tax purposes $2,212,583,119 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: 0.57% of the first $500 million of average net assets, 0.475% of the next $500 million, 0.4275% of the next $500 million and 0.38% thereafter. Effective January 28, 2004, Putnam Management has agreed to limit its compensation (and, to the extent necessary, bear other expenses) through September 30, 2005, to the extent that the fund's net expenses as a percentage of average net assets exceed the average expense ratio for the fund's Lipper peer group of front-end load funds. For the year ended September 30, 2004, Putnam Management did not waive any of its management fee to the fund. For the year ended September 30, 2004, Putnam Management has assumed $89,352 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 year ended September 30, 2004, the fund paid PFTC $3,051,408 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 year ended September 30, 2004, the fund's expenses were reduced by $156,334 under these arrangements. Each independent Trustee of the fund receives an annual Trustee fee, of which $2,236, 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, class C, class M and class R 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 an annual rate of up to 0.35%, 1.00%, 1.00%, 1.00% and 1.00% of the average net assets attributable to class A, class B, class C, class M and class R shares, respectively.

Note 5 Regulatory matters and litigation On April 8, 2004, Putnam Management entered into agreements with the Securities and Exchange Commission ("SEC") and the Massachusetts Securities Division representing a final settlement of all charges brought against Putnam Management by those agencies on October 28, 2003 in connection with excessive short-term trading by Putnam employees and, in the case of the charges brought by the Massachusetts Securities Division, by participants in some Putnam-administered 401(k) plans. 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. Review of these matters by counsel for Putnam Management and by separate independent counsel for the Putnam funds and their independent Trustees is continuing. The fund may experience increased redemptions as a result of these matters, which could result in increased transaction costs and operating expenses.

Class Y shares are offered exclusively to clients that meet the eligibility requirements specified in the fund's prospectus for such shares. Performance of class Y shares, which do not incur a front-end load, a distribution fee, or a contingent deferred sales charge, will differ from the performance of class A, B, C, M, and R shares, which are discussed more extensively in the annual report. RESULTS AT A GLANCE - ---------------------------------------------------------------------------- Total return for periods ended 9/30/04 NAV 1 year 3.09% 5 years 33.92 Annual average 6.02 10 years 91.45 Annual average 6.71 Life of fund (since class A inception, 2/8/84) Annual average 7.71 Share value: NAV 9/30/03 $13.18 9/30/04 $13.22 - ---------------------------------------------------------------------------- Distributions: No. Income Capital gains Total 12 $0.36 -- $0.36 - ---------------------------------------------------------------------------- Please note that past performance is not indicative of future results. More recent returns may be more or less than those shown. Returns shown for class Y shares for periods prior to their inception (4/11/94) are derived from the historical performance of class A shares, and are not adjusted to reflect the initial sales charge currently applicable to class A shares. These returns have not been adjusted to reflect differences in operating expenses which, for class Y shares, typically are lower than the operating expenses applicable to class A shares. All returns assume reinvestment of distributions at net asset value. Investment return and principal value will fluctuate so your shares, when redeemed, may be worth more or less than their original cost. See full report for information on comparative benchmarks.

Code of Ethics: - ----------------------- All officers of the Fund, including its principal executive, financial and accounting officers, are employees of Putnam Investment Management, LLC, the Fund's investment manager. As such they are subject to a comprehensive Code of Ethics adopted and administered by Putnam Investments which is designed to protect the interests of the firm and its clients. The Fund has adopted a Code of Ethics which incorporates the Code of Ethics of Putnam Investments with respect to all of its officers and Trustees who are employees of Putnam Investment Management, LLC. For this reason, the Fund has not adopted a separate code of ethics governing its principal executive, financial and accounting officers. Item 3. Audit Committee Financial Expert: - ----------------------------------------- The Funds' Audit and Pricing Committee is comprised solely of Trustees who are "independent" (as such term has been defined by the Securities and Exchange Commission ("SEC") in regulations implementing Section 407 of the Sarbanes-Oxley Act (the "Regulations")). The Trustees believe that each of the members of the Audit and Pricing Committee also possess a combination of knowledge and experience with respect to financial accounting matters, as well as other attributes, that qualify them for service on the Committee. In addition, the Trustees have determined that all members of the Funds' Audit and Pricing Committee meet the financial literacy requirements of the New York Stock Exchange's rules and that Mr. Patterson and Mr. Stephens qualify as "audit committee financial experts" (as such term has been defined by the Regulations) based on their review of their pertinent experience and education. Certain other Trustees, although not on the Audit and Pricing Committee, would also qualify as "audit committee financial experts." The SEC has stated that the designation or identification of a person as an audit committee financial expert pursuant to this Item 3 of Form N-CSR does not impose on such person any duties, obligations or liability that are greater than the duties, obligations and liability imposed on such person as a member of the Audit and Pricing Committee and the Board of Trustees in the absence of such designation or identification. Item 4.

All Other Fees Fees represent fees billed for services relating relating interfund trading and the registration of securities in Japan. Pre-Approval Policies of the Audit and Pricing Committee. The Audit and Pricing Committee of the Putnam funds has determined that, as a matter of policy, all work performed for the funds by the funds' independent auditors will be pre-approved by the Committee and will generally not be subject to pre-approval procedures. Under certain circumstances, the Audit and Pricing Committee believes that it may be appropriate for Putnam Investment Management, LLC ("Putnam Management") and certain of its affiliates to engage the services of the funds' independent auditors, but only after prior approval by the Committee. Such requests are required to be submitted in writing to the Committee and explain, among other things, the nature of the proposed engagement, the estimated fees, and why this work must be performed by that particular audit firm. The Committee will review the proposed engagement at its next meeting. Since May 6, 2003, all work performed by the independent auditors for the funds, Putnam Management and any entity controlling, controlled by or under common control with Putnam Management that provides ongoing services to the fund was pre-approved by the Committee or a member of the Committee pursuant to the pre-approval policies discussed above. Prior to that date, the Committee had a general policy to pre-approve the independent auditor's engagements for non-audit services with the funds, Putnam Management and any entity controlling, controlled by or under common control with Putnam Management that provides ongoing services to the fund. The following table presents fees billed by the fund's principal auditor for services required to be approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X.
