Consider these risks before investing: Capital gains, if any, are taxable for federal and, in most cases, state purposes. Income from federally tax-exempt funds may be subject to state and local taxes. Bond investments are subject to interest-rate risk (the risk of bond prices falling if interest rates rise) and credit risk (the risk of an issuer defaulting on interest or principal payments). Interest-rate risk is greater for longer-term bonds, and credit risk is greater for below-investment-grade bonds. Unlike bonds, funds that invest in bonds have fees and expenses. The fund may invest significantly in particular segments of the tax-exempt debt market, making it more vulnerable to fluctuations in the values of the securities it holds than a fund that invests more broadly. Interest the fund receives might be taxable. The value of bonds in the fund’s portfolio may fall or fail to rise over time for several reasons, including general financial market conditions, changing market perceptions of the risk of default, changes in government intervention, and factors related to a specific issuer or industry. These factors may also lead to periods of high volatility and reduced liquidity in the bond markets. You can lose money by investing in the fund.

Message from the Trustees

Dear Fellow Shareholder:

The U.S. economic recovery is gaining steam, with three consecutive quarters of positive GDP growth, accelerated hiring, and rising consumer confidence, which recently hit multi-year highs. U.S. markets, however, have experienced some turbulence since the start of the year.

Cheaper energy prices benefit consumers and many businesses, but the sharp decline in oil prices has also fostered uncertainty. A stronger U.S. dollar may hurt profits for many large multinational companies headquartered in the United States that rely on exports for growth. In addition, investors appear to be anticipating when the Federal Reserve will begin raising interest rates. Overseas growth, meanwhile, remains tepid at best.

In an economically uncertain environment, it can be worthwhile to consider a range of investment opportunities. Putnam invests across many asset classes and pursues flexible strategies that seek out opportunities for growth or income with careful awareness of risk. Our experienced equity and fixed-income teams employ new ways of thinking and integrate innovative investment ideas into time-tested, traditional strategies. In today’s environment, it is also important to rely on your financial advisor, who can ensure your portfolio matches your individual goals and tolerance for risk.

As always, thank you for investing with Putnam.

Respectfully yours,

Robert L. Reynolds

Annualized total return (%) comparison as of 1/31/15

Current performance may be lower or higher than the quoted past performance, which cannot guarantee future results. Share price, principal value, and return will fluctuate, and you may have a gain or a loss when you sell your shares. Performance of class A shares assumes reinvestment of distributions and does not account for taxes. Fund returns in the bar chart do not reflect a sales charge of 4.00%; had they, returns would have been lower. See pages 5 and 11–13 for additional performance information. For a portion of the periods, the fund had expense limitations, without which returns would have been lower. To obtain the most recent month-end performance, visit putnam.com.

Interview with your fund’s portfolio manager

Thalia Meehan, CFA

Thalia, what was the municipal bond market environment like during the six-month reporting period ended January 31, 2015?

Municipal bonds enjoyed solid absolute and relative performance during the reporting period. The asset class, as measured by the Barclays Municipal Bond Index, posted positive monthly gains and a six-month return that surpassed stocks [S&P 500 Index] and bonds [Barclays U.S. Aggregate Bond Index].

The accommodative policies of central banks around the globe to promote growth in their respective economies contributed to an environment of low interest rates, which helped to push municipal bond prices higher. With the U.S. economy further along in its recovery, however, the Federal Reserve terminated its bond-buying stimulus program this past October. The plunging price of oil added a new dimension to the debate on U.S. growth. One of the more immediate effects of falling oil prices is on inflation, which, if it stays low, should grant the Federal Reserve more flexibility to hold off raising rates.

Technical [supply/demand] factors also provided price support to municipal bonds, as strong investor demand continued to exceed supply. In addition, there were positive credit developments at the state level as the benefits of stronger U.S. growth rippled throughout the economy. Several states, including California and New York, benefited from their improving economies, disciplined fiscal leadership, and structurally

balanced operations, which in turn led to an improved ratings outlook for those states. Accordingly, upgrades for U.S. public finance rating revisions led downgrades in the fourth quarter of 2014 — the first time since 2008 [Moody’s Investors Service].

How did Putnam AMT-Free Municipal Fund perform against this backdrop?

For the six months ended January 31, 2015, the fund outperformed its benchmark, the Barclays Municipal Bond Index, and the average return of its Lipper peer group.

How was the fund positioned during the reporting period?

We maintained our defensive bias in the portfolio because we believed that the municipal bond market’s attractive returns during the period could be attributed primarily to a combination of lower interest rates and strong market technicals. We kept the fund’s duration positioning, or interest-rate sensitivity, below that of its Lipper peer group. This included maintaining a slightly higher-than-average cash position in the portfolio to help shelter it from price pressures, given the risk of interest rates moving higher. We also believed that carrying a slightly higher-than-average cash balance gave us greater flexibility to act swiftly when timely investment opportunities presented themselves.

We continued to emphasize essential service revenue bonds, which are typically issued by state and local government entities to finance

specific revenue-generating projects. While we believed that conditions were improving at the state and local levels, we continued to underweight local general obligation [G.O.] bonds relative to the benchmark. These securities rely on the taxing power of the issuer and the health of the local economy to make payments from property taxes or sales and income taxes.

Relative to the benchmark, the fund retained an overweight exposure to municipal bonds rated Baa. In terms of sectors, we favored transportation, higher education, and essential service utilities bonds in the portfolio relative to the fund’s Lipper peer group. Overall, this positioning contributed positively to performance. Our shorter-duration interest-rate positioning was one of the biggest detractors from relative performance versus our Lipper peers, as interest rates moved lower during the period. Underweight exposures to Puerto Rico bonds also dampened results as compared with the fund’s Lipper peer group. However, we currently plan to maintain our underweight exposure to issuers in Puerto Rico, given our negative credit outlook for the Commonwealth. Finally, our underweight to non-rated bonds versus our Lipper peers was a headwind for performance, as demand

Credit qualities are shown as a percentage of the fund’s net assets as of 1/31/15. A bond rated Baa or higher (MIG3/VMIG3 or higher, for short-term debt) is considered investment grade. The chart reflects Moody’s ratings; percentages may include bonds or derivatives not rated by Moody’s but rated by Standard & Poor’s (S&P) or, if unrated by S&P, by Fitch ratings, and then included in the closest equivalent Moody’s rating based on analysis of these agencies’ respective ratings criteria. Moody’s ratings are used in recognition of its prominence among rating agencies and breadth of coverage of rated securities. Ratings may vary over time.

for high-yield municipal bonds helped push prices higher.

What is contributing to the imbalance in supply and demand?

The declining volume of new long-term municipal bonds coming to market was due in part to state and local governments undertaking fewer projects while turning their fiscal attention toward funding employee pensions and other fixed costs in their budgets. Combined with maturing debt and early redemptions of existing municipal bonds, the municipal bond market contracted 4% to $3.6 trillion in 2014, according to Bloomberg.

Meanwhile, crossover buyers and hedge fund investors, who appeared to have been drawn to the competitive yields and attractive relative value offered by this asset class rather than by its tax benefit, joined traditional tax-sensitive retail investors to create strong demand. Consequently, the municipal market saw positive inflows to tax-free mutual funds in 2014 — making the year one of the best on record for the asset class, historically speaking. Tax-free high-yield and intermediate-term bond funds were the primary beneficiaries of this strong investor interest.

Some isolated credit situations continue to make headlines, but would you say that the creditworthiness of the municipal bond market remains strong?

While revenue growth has been sluggish in comparison with past recoveries, we believe

the overall fiscal health and creditworthiness of the municipal bond market improved during 2014. Of course, there are outliers, but for the most part, these have been isolated credit situations, in our view. Despite a volatile year that included a downgrade to below investment grade and fluctuating bond performance, Puerto Rico underperformed the broader municipal market but still managed to post positive returns during 2014. We continue to maintain a negative fundamental outlook on the territory given the continued contraction of the island’s economy, which we believe will continue to weigh on credits of the various issuing entities. In Detroit, Michigan, and Stockton, California, we saw the bankruptcy processes play out. The outcomes call into question the long-held notion that G.O. bonds are safer than revenue bonds.

What should tax-sensitive investors know about the alternative minimum tax [AMT] as we enter 2015?

The AMT is a separate, parallel income tax system introduced in 1969 that disallows some popular tax breaks and certain itemized deductions to make sure wealthier taxpayers pay their share of taxes. The Urban-Brookings Tax Policy Center estimates that 3.8 million taxpayers filing in 2015 will be subject to the AMT and will pay an average AMT of $7,028 [Aggregate AMT Projections, 2011–2022]. Putnam AMT-Free Municipal Fund is actively managed to avoid bonds whose income would be subject to the AMT, thereby helping to reduce taxpayers’ tax burden.

There have not been any new developments with regard to the AMT since the American Taxpayer Relief Act of 2012. This legislation set a higher permanent exemption for 2012 and indexed that exemption amount and other AMT parameters for inflation going forward. Looking ahead, we do not foresee any changes to the AMT, as we believe it is unlikely that Congress will enact any major overhaul of the tax code in today’s polarized political environment.

What factors are likely to influence the performance of municipal bonds in the coming months?

While investors should stay mindful of the long-term potential for tax reform, we believe the most significant driver of municipal bond returns in 2015 will be the Fed’s interest-rate policy and its effect on demand for the asset class. At their closely watched meeting this past December, Fed officials modified their policy statement by adding that they “can be patient” on the timing of rate increases. But questions about the timing of an increase are likely to dominate the public discourse until the central bank implements its first rate increase. Accordingly, we believe the Fed’s actions, along with the direction of longer-term U.S. Treasuries, will highly influence the performance of municipal bonds in 2015.

Lower oil and energy prices should be a net positive for the municipal bond market, in our opinion. Certain sectors, such as transportation — notably airlines — and toll roads, could see a positive impact from the decline in prices. However, we believe oil-producing states, such as Texas, North Dakota, and Alaska, are likely to see falling revenues as production decreases or ceases for a period of time.

In the cases of Alaska and North Dakota, however, these states do not issue much municipal bond debt and have set aside what we believe are healthy reserves to ease budget pressures that typically accompany such a downturn. In the case of Texas, we believe the decline in oil and energy prices is likely to be more widely felt. If oil prices remain low for an extended period of time, affected issuers may come under more pressure and be subject to credit downgrades or defaults, in our view. The susceptibility of local G.O. bonds to macroeconomic

AMT-Free Municipal Fund     9

developments, such as a sharp decline in oil prices, reinforces our predisposition to underweight G.O. bonds in the portfolio relative to the benchmark.

In this environment, we will continue to manage the fund with an eye toward keeping its interest-rate sensitivity lower than that of its Lipper peers. As part of this strategy, we believe overweighting bonds rated A and Baa while managing duration with cash and security selection will be the best path.

IN THE NEWS

How can an increase in the unemployment rate — to 5.7% in January 2015 from 5.6% in December 2014 — mean good news? The answer: More than one million people entered the workforce in January — which includes those actively seeking work. This is good news because it appeared that many people had abandoned looking for a job altogether in the wake of the Great Recession. That’s changing. The labor participation rate ticked up to 62.9% in January from 62.7% in December, according to the Bureau of Labor Statistics (BLS). Many believe that, for the economic recovery to continue, more people who have been sitting on the sidelines will need to reenter the labor market, even though they may not land a job right away. The BLS also noted that 257,000 jobs were added in January, slightly above expectations. More importantly, figures from previous months were revised higher: There were 329,000 additional jobs in December and an even more impressive 423,000 jobs in November. The BLS also reported a gain in average hourly earnings, which rose 0.5% in January after declining slightly in December. Wage growth might be luring people back to the workforce, particularly within lower-paying industries such as retail.

Current performance may be lower or higher than the quoted past performance, which cannot guarantee future results. After-sales-charge returns for class A and M shares reflect the deduction of the maximum 4.00% and 3.25% sales charge, respectively, levied at the time of purchase. Class B share returns after contingent deferred sales charge (CDSC) reflect the applicable CDSC, which is 5% in the first year, declining over time to 1% in the sixth year, and is eliminated thereafter. Class C share returns after CDSC reflect a 1% CDSC for the first year that is eliminated thereafter. Class Y shares have no initial sales charge or CDSC. Performance for class A, C, M, and Y shares before their inception is derived from the historical performance of class B shares, adjusted for the applicable sales charge (or CDSC) and, for class C shares, the higher operating expenses for such shares.

For a portion of the periods, the fund had expense limitations, without which returns would have been lower.

Class B share performance reflects conversion to class A shares after eight years.

Ending value (after expenses)	$1,021.32	$1,018.20	$1,017.44	$1,019.96	$1,022.48

*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 average net assets for the six months ended 1/31/15. The expense ratio may differ for each share class.

†Expenses are calculated by multiplying the expense ratio by the average account value for the six-month period; then multiplying the result by the number of days in the six-month period; and then dividing that result by the number of days in the year.

Terms and definitions

Important terms

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.

Before sales charge, or net asset value, is the price, or value, of one share of a mutual fund, without a sales charge. Before-sales-charge figures fluctuate with market conditions, and are calculated by dividing the net assets of each class of shares by the number of outstanding shares in the class.

After sales charge is the price of a mutual fund share plus the maximum sales charge levied at the time of purchase. After-sales-charge performance figures shown here assume the 4.00% maximum sales charge for class A shares and 3.25% for class M shares.

Contingent deferred sales charge (CDSC) is generally 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 over time 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.

Share classes

Class A shares are generally subject to an initial sales charge and no CDSC (except on certain redemptions of shares bought without an initial sales charge).

Class B shares are not subject to an initial sales charge and may be subject to a CDSC.

Class C shares are not subject to an initial sales charge and are subject to a CDSC 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 CDSC.

Class Y shares are not subject to an initial sales charge or CDSC, and carry no 12b-1 fee. They are generally only available to corporate and institutional clients and clients in other approved programs.

Fixed-income terms

Current rate is the annual rate of return earned from dividends or interest of an investment. Current rate is expressed as a percentage of the price of a security, fund share, or principal investment.

Yield curve is a graph that plots the yields of bonds with equal credit quality against their differing maturity dates, ranging from shortest to longest. It is used as a benchmark for other debt, such as mortgage or bank lending rates.

Comparative indexes

Barclays Municipal Bond Index is an unmanaged index of long-term fixed-rate investment-grade tax-exempt bonds.

Barclays U.S. Aggregate Bond Index is an unmanaged index of U.S. investment-grade fixed-income securities.

BofA Merrill Lynch U.S. 3-Month Treasury Bill Index is an unmanaged index that seeks to measure the performance of U.S. Treasury bills available in the marketplace.

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 mutual funds. Its rankings do not reflect sales charges. Lipper rankings are based on total return at net asset value relative to other funds that have similar current investment styles or objectives as determined by Lipper. Lipper may change a fund’s category assignment at its discretion. Lipper category averages reflect performance trends for funds within a category.

Fund portfolio holdings

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 Form N-Q on the SEC’s website at www.sec.gov. In addition, the fund’s Form N-Q may be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C.

Financial statements

A guide to 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 non-investment 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 liquidation preference of 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. Dividend sources are estimated at the time of declaration. Actual results may vary. Any non-taxable return of capital cannot be determined until final tax calculations are completed after the end of the fund’s fiscal year.

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 highlights table also includes the current reporting period.

	Notes to the fund’s portfolio
	Unless noted otherwise, the notes to the fund’s portfolio are for the close of the fund’s reporting period, which ran from August 1, 2014 through January 31, 2015 (the reporting period). Within the following notes to the portfolio, references to “ASC 820” represent Accounting Standards Codification 820 Fair Value Measurements and Disclosures and references to “OTC”, if any, represent over-the-counter.
*	Percentages indicated are based on net assets of $381,899,915.
**	The Moody’s, Standard & Poor’s or Fitch ratings indicated are believed to be the most recent ratings available at the close of the reporting period for the securities listed. Ratings are generally ascribed to securities at the time of issuance. While the agencies may from time to time revise such ratings, they undertake no obligation to do so, and the ratings do not necessarily represent what the agencies would ascribe to these securities at the close of the reporting period. Securities rated by Putnam are indicated by “/P.” Securities rated by Fitch are indicated by “/F.” If a security is insured, it will usually be rated by the ratings organizations based on the financial strength of the insurer. For further details regarding security ratings, please see the Statement of Additional Information.
	Debt obligations are considered secured unless otherwise indicated.
	144A after the name of an issuer represents securities exempt from registration under Rule 144A under the Securities Act of 1933, as amended. These securities may be resold in transactions exempt from registration, normally to qualified institutional buyers.
	On Mandatory Put Bonds, the rates shown are the current interest rates at the close of the reporting period and the dates shown represent the next mandatory put dates.
	The dates shown parenthetically on prerefunded bonds represent the next prerefunding dates.
	The dates shown on debt obligations are the original maturity dates.
	The fund had the following sector concentrations greater than 10% at the close of the reporting period (as a percentage of net assets):
	Utilities	17.4%
	Health care	16.1
	Transportation	13.6
	Local debt	13.2
	The fund had the following insurance concentration greater than 10% at the close of the reporting period (as a percentage of net assets):
	NATL	11.2%

ASC 820 establishes a three-level hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of the fund’s investments. The three levels are defined as follows:

Level 1: Valuations based on quoted prices for identical securities in active markets.

Level 2: Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3: Valuations based on inputs that are unobservable and significant to the fair value measurement.

The following is a summary of the inputs used to value the fund’s net assets as of the close of the reporting period:

	Valuation inputs
Investments in securities:	Level 1	Level 2	Level 3
Municipal bonds and notes	$—	$377,439,512	$—
Totals by level	$—	$377,439,512	$—
During the reporting period, transfers within the fair value hierarchy, if any, did not represent, in the aggregate, more than 1% of the fund’s net assets measured as of the end of the period.

Within the following Notes to financial statements, references to “State Street” represent State Street Bank and Trust Company, references to “the SEC” represent the Securities and Exchange Commission, references to “Putnam Management” represent Putnam Investment Management, LLC, the fund’s manager, an indirect wholly-owned subsidiary of Putnam Investments, LLC and references to “OTC”, if any, represent over-the-counter. Unless otherwise noted, the “reporting period” represents the period from August 1, 2014 through January 31, 2015.

Putnam AMT-Free Municipal Fund (the fund) is a diversified series of Putnam Tax-Free Income Trust (the Trust), a Massachusetts business trust registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. The goal of the fund is to seek high current income exempt from federal income tax. The fund invests mainly in bonds that pay interest that is exempt from federal income tax, are investment grade in quality and have intermediate- to long-term maturities (three years or longer). The fund does not intend to invest in securities the interest on which is subject to the alternative minimum tax (AMT). Putnam Management may consider, among other factors, credit, interest rate and prepayment risks, as well as general market conditions, when deciding whether to buy or sell investments.

The fund offers class A, class B, class C, class M and class Y shares. Class A and class M shares are sold with a maximum front-end sales charge of 4.00% and 3.25%, respectively, and generally do not pay a contingent deferred sales charge. Class B shares, which convert to class A shares after approximately eight years, do not pay a front-end sales charge and are subject to a contingent deferred sales charge if those shares are redeemed within six years of purchase. Class C shares have a one-year 1.00% contingent deferred sales charge and do not convert to class A shares. The expenses for class A, class B, class C, and class M shares may differ based on the distribution fee of each class, which is identified in Note 2. Class Y shares, which are sold at net asset value, are generally subject to the same expenses as class A, class B, class C, and class M shares, but do not bear a distribution fee. Class Y shares are not available to all investors.

In the normal course of business, the fund enters into contracts that may include agreements to indemnify another party under given circumstances. The fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be, but have not yet been, made against the fund. However, the fund’s management team expects the risk of material loss to be remote.

Note 1: Significant accounting policies

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. Actual results could differ from those estimates. Subsequent events after the Statement of assets and liabilities date through the date that the financial statements were issued have been evaluated in the preparation of the financial statements.

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. If the fund were liquidated, shares of each class would receive their pro-rata share of the net assets of the fund. In addition, the Trustees declare separate dividends on each class of shares.

Security valuation Portfolio securities and other investments are valued using policies and procedures adopted by the Board of Trustees. The Trustees have formed a Pricing Committee to oversee the implementation of these procedures and has delegated responsibility for valuing the fund’s assets in accordance with these procedures to Putnam Management. Putnam Management has established an internal Valuation Committee that is responsible for making fair value determinations, evaluating the effectiveness of the pricing policies of the fund and reporting to the Pricing Committee.

Tax-exempt bonds and notes are generally valued on the basis of valuations provided by an independent pricing service approved by the Trustees. Such services use information with respect to transactions in bonds, quotations from bond dealers, market transactions in comparable securities and various relationships between securities in determining value. These securities will generally be categorized as Level 2.

AMT-Free Municipal Fund     37

Certain investments, including certain restricted and illiquid securities and derivatives, are also valued at fair value following procedures approved by the Trustees. To assess the continuing appropriateness of fair valuations, the Valuation Committee reviews and affirms the reasonableness of such valuations on a regular basis after considering all relevant information that is reasonably available. Such valuations and procedures are reviewed periodically by the Trustees. These valuations consider such factors as significant market or specific security events such as interest rate or credit quality changes, various relationships with other securities, discount rates, U.S. Treasury, U.S. swap and credit yields, index levels, convexity exposures, recovery rates, sales and other multiples and resale restrictions. These securities are classified as Level 2 or as Level 3 depending on the priority of the significant inputs. The fair value of securities is generally determined as the amount that the fund could reasonably expect to realize from an orderly disposition of such securities over a reasonable period of time. By its nature, a fair value price is a good faith estimate of the value of a security in a current sale and does not reflect an actual market price, which may be different by a material amount.

Security transactions and related investment income Security transactions are recorded on the trade date (the 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.

Securities purchased or sold on a delayed delivery basis may be settled at a future date beyond customary settlement time; interest income is accrued based on the terms of the securities. Losses may arise due to changes in the fair value of the underlying securities or if the counterparty does not perform under the contract.

Interfund lending The fund, along with other Putnam funds, may participate in an interfund lending program pursuant to an exemptive order issued by the SEC. This program allows the fund to borrow from other Putnam funds that permit such transactions. Interfund lending transactions are subject to each fund’s investment policies and borrowing and lending limits. Interest earned or paid on the interfund lending transaction will be based on the average of certain current market rates. During the reporting period, the fund did not utilize the program.

Lines of credit The fund participates, along with other Putnam funds, in a $392.5 million unsecured committed line of credit and a $235.5 million unsecured uncommitted line of credit, both provided by State Street. Borrowings may be made for temporary or emergency purposes, including the funding of shareholder redemption requests and trade settlements. Interest is charged to the fund based on the fund’s borrowing at a rate equal to the Federal Funds rate plus 1.25% for the committed line of credit and the Federal Funds rate plus 1.30% for the uncommitted line of credit. A closing fee equal to 0.04% of the committed line of credit and 0.04% of the uncommitted line of credit has been paid by the participating funds. In addition, a commitment fee of 0.11% per annum on any unutilized portion of the committed line of credit is allocated to the participating funds based on their relative net assets and paid quarterly. During the reporting period, the fund had no borrowings against these arrangements.

Federal taxes It is the policy of the fund to distribute all of its income within the prescribed time period and otherwise comply with the provisions of the Internal Revenue Code of 1986, as amended (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.

The fund is subject to the provisions of Accounting Standards Codification 740 Income Taxes (ASC 740). ASC 740 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The fund did not have a liability to record for any unrecognized tax benefits in the accompanying financial statements. 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. Each of the fund’s federal tax returns for the prior three fiscal years remains subject to examination by the Internal Revenue Service.

At July 31, 2014, the fund had a capital loss carryover of $9,541,054 available to the extent allowed by the Code to offset future net capital gain, if any. The amounts of the carryovers and the expiration dates are:

Loss carryover
Short-term	Long-term	Total	Expiration
$3,772,457	$2,004,593	$5,777,050	*
3,337,309	N/A	3,337,309	July 31, 2018
426,695	N/A	426,695	July 31, 2019

*Under the Regulated Investment Company Modernization Act of 2010, the fund will be permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. However, any losses incurred will be required to be utilized prior to the losses incurred in pre-enactment tax years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law.

Pursuant to federal income tax regulations applicable to regulated investment companies, the fund has elected to defer certain capital losses of $938,847 recognized during the period between November 1, 2013 and July 31, 2014 to its fiscal year ending July 31, 2015.

The aggregate identified cost on a tax basis is $336,495,911, resulting in gross unrealized appreciation and depreciation of $41,360,902 and $417,301, respectively, or net unrealized appreciation of $40,943,601.

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. Dividend sources are estimated at the time of declaration. Actual results may vary. Any non-taxable return of capital cannot be determined until final tax calculations are completed after the end of the fund’s fiscal year. 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.

Expenses of the Trust Expenses directly charged or attributable to any fund will be paid from the assets of that fund. Generally, expenses of the Trust will be allocated among and charged to the assets of each fund on a basis that the Trustees deem fair and equitable, which may be based on the relative assets of each fund or the nature of the services performed and relative applicability to each fund.

Note 2: Management fee, administrative services and other transactions

The fund pays Putnam Management a management fee (based on the fund’s average net assets and computed and paid monthly) at annual rates that may vary based on the average of the aggregate net assets of most open-end funds, as defined in the fund’s management contract, sponsored by Putnam Management. Such annual rates may vary as follows:

0.590%	of the first $5 billion,
0.540%	of the next $5 billion,
0.490%	of the next $10 billion,
0.440%	of the next $10 billion,
0.390%	of the next $50 billion,
0.370%	of the next $50 billion,
0.360%	of the next $100 billion and
0.355%	of any excess thereafter.

Putnam Management has contractually agreed, through June 30, 2015, to waive fees or reimburse the fund’s expenses to the extent necessary to limit the cumulative expenses of the fund, exclusive of brokerage, interest, taxes, investment-related expenses, extraordinary expenses, acquired fund fees and expenses and payments under the fund’s investor servicing contract, investment management contract and distribution plans, on a fiscal year-to-date basis to an annual rate of 0.20% of the fund’s average net assets over such fiscal year-to-date period. During the reporting period, the fund’s expenses were not reduced as a result of this limit.

Putnam Investments Limited (PIL), an affiliate of Putnam Management, is authorized by the Trustees to manage a separate portion of the assets of the fund as determined by Putnam Management from time to time. Putnam Management pays a quarterly sub-management fee to PIL for its services at an annual rate of 0.40% of the average net assets of the portion of the fund managed by PIL.

AMT-Free Municipal Fund     39

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 State Street. Custody fees are based on the fund’s asset level, the number of its security holdings and transaction volumes.

Putnam Investor Services, Inc., an affiliate of Putnam Management, provides investor servicing agent functions to the fund. Putnam Investor Services, Inc. received fees for investor servicing based on the fund’s retail asset level, the number of shareholder accounts in the fund and the level of defined contribution plan assets in the fund. Investor servicing fees will not exceed an annual rate of 0.32% of the fund’s average net assets. During the reporting period, the expenses for each class of shares related to investor servicing fees were as follows:

Class A	$76,616
Class B	735
Class C	6,231
Class M	235
Class Y	6,664
Total	$90,481

The fund has entered into expense offset arrangements with Putnam Investor Services, Inc. and State Street whereby Putnam Investor Services, Inc.’s and State Street’s fees are reduced by credits allowed on cash balances. For the reporting period, the fund’s expenses were reduced by $181 under the expense offset arrangements.

Each Independent Trustee of the fund receives an annual Trustee fee, of which $213, as a quarterly retainer, has been allocated to the fund, and an additional fee for each Trustees meeting attended. Trustees also are reimbursed for expenses they incur relating to their services as Trustees.

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 and were first elected prior to 2004. Benefits under the Pension Plan are equal to 50% of the Trustee’s average annual attendance and retainer fees for the three years ended December 31, 2005. The retirement benefit is payable during a Trustee’s lifetime, beginning the year following retirement, for the number of years of service through December 31, 2006. 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 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 Limited Partnership, an indirect wholly-owned subsidiary of Putnam Investments, LLC, for services provided and expenses incurred in distributing shares of the fund. The Plans provide for payments by the fund to Putnam Retail Management Limited Partnership at an annual rate of up to 0.35%, 1.00%, 1.00% and 1.00% of the average net assets attributable to class A, class B, class C and class M shares, respectively. The Trustees have approved payment by the fund at the annual rate of 0.85%, 1.00% and 0.50% of the average net assets for class B, class C and class M shares, respectively. For class A shares, the annual payment rate will equal the weighted average of (i) 0.20% of the net assets of the fund attributable to class A shares purchased and paid for prior to April 1, 2005 and (ii) 0.25% of all other net assets of the fund attributable to class A shares. During the reporting period, the class specific expenses related to distribution fees were as follows:

Class A	$379,096
Class B	13,314
Class C	132,822
Class M	2,503
Total	$527,735

For the reporting period, Putnam Retail Management Limited Partnership, acting as underwriter, received net commissions of $5,710 and $222 from the sale of class A and class M shares, respectively, and received $0 and $8 in contingent deferred sales charges from redemptions of class B and class C shares, respectively.

A deferred sales charge of up to 1.00% is assessed on certain redemptions of class A shares. For the reporting period, Putnam Retail Management Limited Partnership, acting as underwriter, received $13,897 on class A redemptions.
