What makes Putnam different?

In 1830, Massachusetts Supreme Judicial Court Justice Samuel Putnam established The Prudent Man Rule, a legal foundation for responsible money management.

THE PRUDENT MAN RULE

All that can be required of a trustee to invest is that he shall conduct himself faithfully and exercise a sound discretion. He is to observe how men of prudence, discretion, and intelligence manage their own affairs, not in regard to speculation, but in regard to the permanent disposition of their funds, considering the probable income, as well as the probable safety of the capital to be invested.

A time-honored tradition in money management

Since 1937, our values have been rooted in a profound sense of responsibility for the money entrusted to us.

A prudent approach to investing

We use a research-driven team approach to seek consistent, dependable, superior investment results over time, although there is no guarantee a fund will meet its objectives.

Funds for every investment goal

We offer a broad range of mutual funds and other financial products so investors and their financial representatives can build diversified portfolios.

A commitment to doing what’s right for investors

We have below-average expenses and stringent investor protections, and provide a wealth of information about the Putnam funds.

Industry-leading service

We help investors, along with their financial representatives, make informed investment decisions with confidence.

Message from the Trustees

Dear Fellow Shareholder

Investors continue to keep a close watch on the course of the economy. Globally, it appears that, assuming economic growth exceeds 4% in 2006, we will have seen the strongest economic performance over a four-year period in over thirty years. Corporate profits have boomed around the world, business capacity utilization rates have moved up, and unemployment rates have come down. Given such a sustained period of robust growth, it is not surprising that prices have begun to rise, inflation rates have crept up, and central banks in many countries, particularly the Federal Reserve (the Fed) in the United States, have pushed interest rates higher.

In recent weeks, investors have worried that these higher rates could threaten the fundamentals of the global economy, prompting a widespread sell-off. However, we believe that today’s higher interest rates, far from being a threat to global economic fundamentals, are in fact an integral part of them. Higher interest rates are bringing business borrowing costs closer to the rate of return available from investments. In our view, this should help provide the basis for a longer and more durable business expansion and a continued healthy investment environment.

You can be assured that the investment professionals managing your fund are closely monitoring the factors that influence the performance of the securities in which your fund invests. Moreover, Putnam Investments’ management team, under the leadership of Chief Executive Officer Ed Haldeman, continues to focus on investment performance and remains committed to putting the interests of shareholders first.

In the following pages, members of your fund’s management team discuss the fund’s performance and strategies for the fiscal period ended May 31, 2006, and provide their outlook for the months ahead. As always, we thank you for your support of the Putnam funds.

Putnam Massachusetts Tax Exempt Income Fund:
potential for tax-advantaged income

Municipal bonds finance important public projects such as schools, roads, and hospitals, and they can help investors keep more of their investment income. Municipal bonds are typically issued by states and local municipalities to raise funds for building and maintaining public facilities, and they offer income that is generally exempt from federal income tax.

For residents of the state where the bond is issued, income is typically exempt from state and any local income taxes as well. While the stated yields on municipal bonds are usually lower than those on taxable bonds, state tax exemption is a powerful advantage because state income tax can erode investment income significantly. And the sheer size of the Massachusetts municipal bond market provides a wide array of investment opportunities.

Putnam Massachusetts Tax Exempt Income Fund seeks to capitalize on investment opportunities in Massachusetts by investing in bonds across a range of market sectors. The fund also combines bonds of differing credit quality to increase income potential. In addition to investing in high-quality bonds, the fund’s management team allocates a smaller portion of the portfolio to lower-rated bonds, which may offer higher income in return for more risk.

When deciding whether to invest in a bond, the fund’s management team considers the risks involved — including credit risk, interest-rate risk, and the risk that the bond will be prepaid. The management team is backed by the resources of Putnam’s fixed-income organization, one of the largest in the investment industry, in which municipal bond analysts are grouped into sector teams and conduct ongoing, rigorous research. Once a bond has been purchased, the team continues to monitor developments that affect the bond market, the sector, and the issuer of the bond.

Municipal bonds may finance a range of projects in your
community and thus play a key role in its development.

The goal of the fund’s in-depth research and active management is to stay a step ahead of the industry and pinpoint opportunities to adjust the fund’s holdings for the benefit of the fund and its shareholders.

The fund concentrates its investments by region and involves more risk than a fund that invests more broadly. Capital gains, if any, are taxable for federal and, in most cases, state purposes. For some investors, investment income may be subject to the federal alternative minimum tax. Tax-free funds may not be suitable for IRAs and other non-taxable accounts. Please consult with your tax advisor for more information. 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.

Understanding tax-equivalent yield

To understand the value of tax-free income, it is helpful to compare a municipal bond’s yield with the “tax-equivalent yield” — the before-tax yield that must be offered by a taxable bond in order to equal the municipal bond’s yield after taxes.

How to calculate tax-equivalent yield:

The tax-equivalent yield equals the municipal bond’s yield divided by “one minus the tax rate.” For example, if a municipal bond’s yield is 5%, then its tax-equivalent yield is 7.7%, assuming the maximum 35% federal tax rate for 2006.

Results for investors subject to lower tax rates would not be as advantageous.

Putnam Massachusetts Tax Exempt Income Fund seeks to provide as high a level of current income free from federal and state of Massachusetts personal income tax as we believe to be consistent with the preservation of capital. It may be suitable for Massachusetts investors seeking tax-free income through a diversified portfolio of municipal bonds issued primarily in Massachusetts.

Report from the fund managers

The year in review

Solid economic growth and rising corporate earnings provided a favorable environment for lower-quality, higher-yielding municipal bonds during the fund’s fiscal year, which ended May 31, 2006. The fund’s positions in the health-care, education, and utilities sectors appreciated as a result, as did the one tobacco settlement issue in the portfolio. The fund also benefited from its relatively short duration positioning, which was designed to reduce the portfolio’s sensitivity to rising interest rates. Consequently, the fund’s return at net asset value (NAV, or without sales charges) surpassed the average return for funds in its Lipper category for the fiscal period. However, given the fund’s single-state focus, its results lagged those of its nationally diversified benchmark. We also think the portfolio’s yield curve positioning — which emphasized intermediate-maturity bonds while limiting exposure to longer-maturity bonds — was a factor in this underperformance.

Market overview

Amid continuing signs of solid economic growth, and the potential for inflation that often accompanies such growth, the Fed increased the federal funds rate eight times during the fund’s fiscal year, lifting this benchmark for overnight loans between banks from 3.00% to 5.00% . Bond yields rose across the maturity spectrum, leading to a convergence of shorter- and longer-term rates. As rates converged, the yield curve — a graphical representation of yields for bonds of comparable quality plotted from the shortest to the longest maturity — flattened.

During the period, tax-exempt bonds generally outperformed comparable Treasury bonds, as prices of tax-exempt bonds declined less than Treasury prices across all maturities. Municipal bonds typically perform better than Treasuries when interest rates are rising. However, the degree to which they outperformed Treasuries was greater than we expected.

7

A robust economy and rising corporate earnings contributed to the strong relative performance of lower-rated bonds. Among uninsured bonds in general and especially bonds rated Baa and below, yield spreads tightened as lower-rated bonds performed better than higher-rated bonds. The superior performance of lower-rated bonds was primarily the result of strong demand by buyers searching for higher yields. Non-rated bonds also rallied. In addition, as a result of favorable legal rulings, tobacco settlement bonds generally outperformed the broader market. Also, airline-related industrial development bonds (IDBs) performed exceptionally well over the period.

Strategy overview

Given our expectation for rising interest rates, we maintained a short (defensive) portfolio duration relative to the fund’s Lipper peer group, a strategy that contributed positively to results for the period as rates rose. Duration is a measure of a fund’s sensitivity to changes in interest rates. Having a shorter-duration portfolio may help protect principal when interest rates rise, but it can reduce appreciation potential when rates fall.

The fund’s yield curve positioning, or the maturity profile of its holdings, detracted from performance during the period but did not negate the positive contribution provided by our duration strategy. In order to keep the fund’s duration short, we limited exposure to longer-maturity bonds,

favoring intermediate-maturity securities instead. However, as the yield curve flattened and shorter- and longer-term yields converged, bonds with longer maturities performed better than their intermediate-maturity counterparts.

In order to offset the effects of a flattening yield curve, the fund used various interest-rate swap contracts. Rather than trading large numbers of securities, which takes time and can be expensive for the fund, these contracts enabled us to manage the fund’s yield curve positioning more efficiently.

The fund’s overweight position in Baa-rated bonds, compared to other funds in its peer group, boosted results as securities in this area of the market continued to perform well. We maintained this overweight because we believed that better relative value existed in bonds rated Baa and higher at this point in the credit cycle, when the narrowing of credit spreads — or the reduced premium investors stand to receive by investing in lower-rated issues — has not been supported by credit fundamentals, in our view. Conversely, the fund’s underweight position in the lowest-rated bonds (i.e., those rated Ba and below), compared to other funds in its peer group, detracted from results as securities in this area of the market rallied.

As mentioned above, the fund’s investments in lower-rated municipal bonds delivered some of the best performance

during the reporting period. After such strong appreciation, we have become more cautious regarding this sector, since we do not believe that investors are being adequately compensated for the increased risk associated with investing in these lower-quality investments. While this decision curbed the fund’s participation in the rally, we think it may help protect the value of the portfolio when credit spreads begin to widen.

The fund’s investments in University of Massachusetts Memorial Medical Center revenue bonds exemplify our strategy in this sector. These bonds, which financed improvements to the hospital, did encounter some unexpected volatility late in 2005, in response to the voluntary closure of the cardiac surgery unit. Management responded quickly to stabilize the situation, and the bonds recovered, as we had expected. In fact, during the fiscal year, the fund sold off a number of University of Massachusetts Memorial revenue bonds and took profits. Our outlook for these bonds remains positive, especially given their attractive coupon, which is the promised rate of interest paid on the bond, and the possibility that they could be pre-refunded — or refinanced, which would elevate the bonds’ perceived credit quality while shortening their maturity.

The fund’s sole tobacco settlement bond, issued by the Children’s Trust Fund of Puerto Rico, contributed positively to results as this type of bond continued to strengthen during the

period. While tobacco settlement bonds generally carry investment-grade ratings of Baa, they are secured by the income stream from tobacco companies’ settlement obligations to the states and generally offer higher yields than bonds of comparable quality.

Puerto Rico municipal bonds offer tax-exempt income to investors in all 50 states and have, over time, proven useful in diversifying the fund’s portfolio. However, general obligation bonds issued by Puerto Rico were downgraded near the end of the period due to financial turmoil that led to a partial government shutdown. Prices of uninsured Puerto Rico bonds declined, providing the fund with an opportunity to add to its holdings at favorable levels. By the end of the period, the fund had increased its Puerto Rico holdings from an underweight position relative to the Lipper peer group to an allocation that is approximately in line with the peer group average.

Please note that the holdings discussed in this report may not have been held by the fund for the entire period. Portfolio composition is subject to review in accordance with the fund’s investment strategy and may vary in the future.

The outlook for your fund

The following commentary reflects anticipated developments that could affect your fund over the next six months, as well as your management team’s plans for responding to them.

We believe that the Fed’s tightening cycle is nearing an end but expect that rates will continue to rise over the near term. Consequently, we currently plan to maintain the fund’s defensive duration because we believe that the municipal bond market may be susceptible to weaker returns in the coming months. A key reason for this belief is the market’s unusually strong performance versus taxable equivalents for the fiscal period. In our view, the municipal market’s exceptional results can be attributed primarily to a combination of robust demand and limited new-issue supply.

It appears to us that the extended rally among lower-rated, higher-yielding bonds may be in its final stages. We base this view, in part, on the fact that the difference in yields between Aaa-rated bonds and Baa-rated bonds — the lowest investment-grade rating — is at its narrowest point since late 1999. In other words, the reward in terms of higher yields for assuming additional credit risk has diminished substantially. Therefore, we remain cautious with respect to securities at the lower end of the credit spectrum.

We continue to have a positive view of defensive sectors such as single-family housing bonds, which performed well over most of the fiscal period. Finally, our view on tobacco settlement bonds remains positive as we believe that they represent good investment opportunities relative to the inherent risks associated with the sector.

Performance assumes reinvestment of distributions and does not account for taxes. Returns at public offering price (POP) for class A and M shares reflect a sales charge of 3.75% and 3.25%, respectively. Class B share returns reflect the applicable contingent deferred sales charge (CDSC), which is 5% in the first year, declining to 1% in the sixth year, and is eliminated thereafter. Class C shares reflect a 1% CDSC the first year that is eliminated thereafter. Performance for class B, C, and M shares before their inception is derived from the historical performance of class A shares, adjusted for the applicable sales charge (or CDSC) and the higher operating expenses for such shares.

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 Massachusetts Tax Exempt Income Fund from December 1, 2005, to May 31, 2006. It also shows how much a $1,000 investment would be worth at the close of the period, assuming actual returns and expenses.

	Class A	Class B	Class C	Class M
Expenses paid per $1,000*	$ 4.26	$ 7.47	$ 8.21	$ 5.71
Ending value (after expenses)	$1,012.20	$1,010.00	$1,008.90	$1,010.70

* Expenses for each share class are calculated using the fund’s annualized expense ratio for each class, which represents the ongoing expenses as a percentage of net assets for the six months ended 5/31/06. The expense ratio may differ for each share class (see the table at the bottom of the next 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.

Estimate the expenses you paid

To estimate the ongoing expenses you paid for the six months ended May 31, 2006, use the calculation method below.

Compare expenses using the SEC’s method

The Securities and Exchange Commission (SEC) has established guidelines to help investors assess fund 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.

	Class A	Class B	Class C	Class M
Expenses paid per $1,000*	$ 4.28	$ 7.49	$ 8.25	$ 5.74
Ending value (after expenses)	$1,020.69	$1,017.50	$1,016.75	$1,019.25

* Expenses for each share class are calculated using the fund’s annualized expense ratio for each class, which represents the ongoing expenses as a percentage of net assets for the six months ended 5/31/06. 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.

You can also compare your fund’s expenses with the average of its peer group, as defined 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.

	Class A	Class B	Class C	Class M
Your fund's annualized
expense ratio*	0.85%	1.49%	1.64%	1.14%
Average annualized expense
ratio for Lipper peer group†	0.91%	1.55%	1.70%	1.20%

* For the fund’s most recent fiscal half year; may differ from expense ratios based on one-year data in the financial highlights.

† Simple average of the expenses of all front-end load funds in the fund’s Lipper peer group, calculated in accordance with Lipper’s standard method for comparing fund expenses (excluding 12b-1 fees and without giving effect to any expense offset and brokerage service arrangements that may reduce fund expenses). This average reflects each fund’s expenses for its most recent fiscal year available to Lipper as of 3/31/06. To facilitate comparison, Putnam has adjusted this average to reflect the 12b-1 fees carried by each class of shares. The peer group may include funds that are significantly smaller or larger than the fund, which may limit the comparability of the fund’s expenses to the simple average, which typically is higher than the asset-weighted average.

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 or other fixed-income instruments 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
	2006	2005	2004	2003	2002
Putnam Massachusetts Tax
Exempt Income Fund	7%	18%	7%	29%	24%
Lipper Massachusetts Municipal
Debt Funds category average	18%	18%	21%	32%	26%

Turnover data for the fund is calculated based on the fund’s fiscal-year period, which ends on May 31. Turnover data for the fund’s Lipper category is calculated based on the average of the turnover of each fund in the category for its fiscal year ended during the indicated year. Fiscal years vary across funds in the Lipper category, which may limit the comparability of the fund’s portfolio turnover rate to the Lipper average. Comparative data for 2006 is based on information available as of 5/31/06.

Your fund’s risk

This risk comparison is designed 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.

Your fund’s Overall Morningstar^® Risk

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 June 30, 2006. 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 2006 Morningstar, Inc. All Rights Reserved.

Fund manager compensation

The total 2005 fund manager compensation that is attributable to your fund is approximately $150,000. This amount includes a portion of 2005 compensation paid by Putnam Management to the fund managers listed in this section for their portfolio management responsibilities, calculated based on the fund assets they manage taken as a percentage of the total assets they manage. The compensation amount also includes a portion of the 2005 compensation paid to the Chief Investment Officer of the team and the Group Chief Investment Officer of the fund’s broader investment category for their oversight responsibilities, calculated based on the fund assets they oversee taken as a percentage of the total assets they oversee. This amount does not include compensation of other personnel involved in research, trading, administration, systems, compliance, or fund operations; nor does it include non-compensation costs. These percentages are determined as of the fund’s fiscal period-end. For personnel who joined Putnam Management during or after 2005, the calculation reflects annualized 2005 compensation or an estimate of 2006 compensation, as applicable.

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.

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 3.75% 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 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. They 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.

Trustee approval of
management contract

General conclusions

The Board of Trustees of the Putnam funds oversees the management of each fund and, as required by law, determines annually whether to approve the continuance of your fund’s management contract with Putnam Management. In this regard, the Board of Trustees, with the assistance of its Contract Committee consisting solely of Trustees who are not “interested persons” (as such term is defined in the Investment Company Act of 1940, as amended) of the Putnam funds (the “Independent Trustees”), requests and evaluates all information it deems reasonably necessary under the circumstances. Over the course of several months beginning in March and ending in June 2005, the Contract Committee met five times to consider the information provided by Putnam Management and other information developed with the assistance of the Board’s independent counsel and independent staff. The Contract Committee reviewed and discussed key aspects of this information with all of the Independent Trustees. Upon completion of this review, the Contract Committee recommended and the Independent Trustees approved the continuance of your fund’s management contract, effective July 1, 2005.

This approval was based on the following conclusions:

* That the fee schedule currently in effect for your fund represents reasonable compensation in light of the nature and quality of the services being provided to the fund, the fees paid by competitive funds and the costs incurred by Putnam Management in providing such services, and

* That such fee schedule represents an appropriate sharing between fund shareholders and Putnam Management of such economies of scale as may exist in the management of the fund at current asset levels.

These conclusions were based on a comprehensive consideration of all information provided to the Trustees and were not the result of any single factor. Some of the factors that figured particularly in the Trustees’ deliberations and how the Trustees considered these factors are described below, although individual Trustees may have evaluated the information presented differently, giving different weights to various factors. It is also important to recognize that the fee arrangements for your fund and the other Putnam funds are the result of many years of review and discussion between the Independent Trustees and Putnam Management, that certain aspects of such arrangements may receive greater scrutiny in some years than others, and that the Trustees’ conclusions may be based, in part, on their consideration of these same arrangements in prior years.

25

Model fee schedules and categories; total expenses

The Trustees’ review of the management fees and total expenses of the Putnam funds focused on three major themes:

* Consistency. The Trustees, working in cooperation with Putnam Management, have developed and implemented a series of model fee schedules for the Putnam funds designed to ensure that each fund’s management fee is consistent with the fees for similar funds in the Putnam family of funds and compares favorably with fees paid by competitive funds sponsored by other investment advisors. Under this approach, each Putnam fund is assigned to one of several fee categories based on a combination of factors, including competitive fees and perceived difficulty of management, and a common fee schedule is implemented for all funds in a given fee category. The Trustees reviewed the model fee schedule then in effect for your fund, including fee levels and breakpoints, and the assignment of the fund to a particular fee category under this structure. (“Breakpoints” refer to reductions in fee rates that apply to additional assets once specified asset levels are reached.) The Trustees concluded that no changes should be made in the fund’s current fee schedule at this time.

* Competitiveness. The Trustees also reviewed comparative fee and expense information for competitive funds, which indicated that, in a custom peer group of competitive funds selected by Lipper Inc., your fund ranked in the 36th percentile in management fees and in the 45th percentile in total expenses (less any applicable 12b-1 fees) as of December 31, 2004 (the first percentile being the least expensive funds and the 100th percentile being the most expensive funds). (Because the fund’s custom peer group is smaller than the fund’s broad Lipper Inc. peer group, this expense comparison may differ from the Lipper peer expense information found elsewhere in this report.) The Trustees noted that expense ratios for a number of Putnam funds, which show the percentage of fund assets used to pay for management and administrative services, distribution (12b-1) fees and other expenses, had been increasing recently as a result of declining net assets and the natural operation of fee breakpoints. They noted that such expense ratio increases were currently being controlled by expense limitations implemented in January 2004 and which Putnam Management, in consultation with the Contract Committee, had committed to maintain at least through 2006. The Trustees expressed their intention to monitor this information closely to ensure that fees and expenses of the Putnam funds continue to meet evolving competitive standards.

* Economies of scale. The Trustees concluded that the fee schedule currently in effect for your fund represents an appropriate sharing of economies of scale at current asset levels. Your fund currently has the benefit of breakpoints in its management fee that provide shareholders with significant economies of scale, which means that the effective management fee rate of a fund (as a percentage of fund assets) declines as a fund grows in size and crosses specified asset thresholds. The Trustees examined the existing breakpoint structure of the Putnam

26

funds’ management fees in light of competitive industry practices. The Trustees considered various possible modifications to the Putnam funds’ current breakpoint structure, but ultimately concluded that the current breakpoint structure continues to serve the interests of fund shareholders. Accordingly, the Trustees continue to believe that the fee schedules currently in effect for the funds represent an appropriate sharing of economies of scale at current asset levels. The Trustees noted that significant redemptions in many Putnam funds, together with significant changes in the cost structure of Putnam Management, have altered the economics of Putnam Management’s business in significant ways. In view of these changes, the Trustees intend to consider whether a greater sharing of the economies of scale by fund shareholders would be appropriate if and when aggregate assets in the Putnam funds begin to experience meaningful growth.

In connection with their review of the management fees and total expenses of the Putnam funds, the Trustees also reviewed the costs of the services to be provided and profits to be realized by Putnam Management and its affiliates from the relationship with the funds. This information included trends in revenues, expenses and profitability of Putnam Management and its affiliates relating to the investment management and distribution services provided to the funds. In this regard, the Trustees also reviewed an analysis of Putnam Management’s revenues, expenses and profitability with respect to the funds’ management contracts, allocated on a fund-by-fund basis.

Investment performance

The quality of the investment process provided by Putnam Management represented a major factor in the Trustees’ evaluation of the quality of services provided by Putnam Management under your fund’s management contract. The Trustees were assisted in their review of the funds’ investment process and performance by the work of the Investment Oversight Committees of the Trustees, which meet on a regular monthly basis with the funds’ portfolio teams throughout the year. The Trustees concluded that Putnam Management generally provides a high-quality investment process — as measured by the experience and skills of the individuals assigned to the management of fund portfolios, the resources made available to such personnel, and in general the ability of Putnam Management to attract and retain high-quality personnel — but also recognize that this does not guarantee favorable investment results for every fund in every time period. The Trustees considered the investment performance of each fund over multiple time periods and considered information comparing the fund’s performance with various benchmarks and with the performance of competitive funds. The Trustees noted the satisfactory investment performance of many Putnam funds. They also noted the disappointing investment performance of certain funds in recent years and continued to discuss with senior management of Putnam Management the factors contributing to such underperformance and actions being taken to improve performance. The Trustees recognized that, in recent years, Putnam Management has made significant changes in its investment personnel and processes and in the fund product line

27

to address areas of underperformance. The Trustees indicated their intention to continue to monitor performance trends to assess the effectiveness of these changes and to evaluate whether additional remedial changes are warranted.

In the case of your fund, the Trustees considered that your fund’s class A share cumulative total return performance at net asset value was in the following percentiles of its Lipper Inc. peer group (Lipper Massachusetts Municipal Debt Funds; compared using tax-adjusted performance to recognize the different federal income tax treatment for capital gains distributions and exempt-interest distributions) for the one-, three-, and five-year periods ended December 31, 2004 (the first percentile being the best-performing funds and the 100th percentile being the worst-performing funds):

One-year period	Three-year period	Five-year period
22nd	32nd	34th

(Because of the passage of time, these performance results may differ from the performance results for more recent periods shown elsewhere in this report. Over the one-, three-, and five-year periods ended December 31, 2004, there were 52, 51, and 46 funds, respectively, in your fund’s Lipper peer group.* Past performance is no guarantee of future performance.)

As a general matter, the Trustees believe that cooperative efforts between the Trustees and Putnam Management represent the most effective way to address investment performance problems. The Trustees believe that investors in the Putnam funds have, in effect, placed their trust in the Putnam organization, under the oversight of the funds’ Trustees, to make appropriate decisions regarding the management of the funds. Based on the responsiveness of Putnam Management in the recent past to Trustee concerns about investment performance, the Trustees believe that it is preferable to seek change within Putnam Management to address performance shortcomings. In the Trustees’ view, the alternative of terminating a management contract and engaging a new investment advisor for an underperforming fund would entail significant disruptions and would not provide any greater assurance of improved investment performance.

Brokerage and soft-dollar allocations; other benefits

The Trustees considered various potential benefits that Putnam Management may receive in connection with the services it provides under the management contract with your fund. These include principally benefits related to brokerage and soft-dollar allocations, whereby a portion of the commissions paid by a fund for brokerage is earmarked to pay for research services that may be utilized by a fund’s investment advisor, subject to the obligation to seek best execution.

* The percentile rankings for your fund’s class A share annualized total return performance in the Lipper Massachusetts Municipal Debt Funds category for the one-, five-, and ten-year periods ended June 30, 2006, were 19%, 26%, and 26%, respectively. Over the one-, five-, and ten-year periods ended June 30, 2006, the fund ranked 10th out of 52, 13th out of 50, and 10th out of 38 funds, respectively. Note that this more recent information was not available when the Trustees approved the continuance of your fund’s management contract.

28

The Trustees believe that soft-dollar credits and other potential benefits associated with the allocation of fund brokerage, which pertains mainly to funds investing in equity securities, represent assets of the funds that should be used for the benefit of fund shareholders. This area has been marked by significant change in recent years. In July 2003, acting upon the Contract Committee’s recommendation, the Trustees directed that allocations of brokerage to reward firms that sell fund shares be discontinued no later than December 31, 2003. In addition, commencing in 2004, the allocation of brokerage commissions by Putnam Management to acquire research services from third-party service providers has been significantly reduced, and continues at a modest level only to acquire research that is customarily not available for cash. The Trustees will continue to monitor the allocation of the funds’ brokerage to ensure that the principle of “best price and execution” remains paramount in the portfolio trading process.

The Trustees’ annual review of your fund’s management contract also included the review of its distributor’s contract and distribution plan with Putnam Retail Management Limited Partnership and the custodian agreement and investor servicing agreement with Putnam Fiduciary Trust Company, all of which provide benefits to affiliates of Putnam Management.

Comparison of retail and institutional fee schedules

The information examined by the Trustees as part of their annual contract review has included for many years information regarding fees charged by Putnam Management and its affiliates to institutional clients such as defined benefit pension plans, college endowments, etc. This information included comparison of such fees with fees charged to the funds, as well as a detailed assessment of the differences in the services provided to these two types of clients. The Trustees observed, in this regard, that the differences in fee rates between institutional clients and the mutual funds are by no means uniform when examined by individual asset sectors, suggesting that differences in the pricing of investment management services to these types of clients reflect to a substantial degree historical competitive forces operating in separate market places. The Trustees considered the fact that fee rates across all asset sectors are higher on average for mutual funds than for institutional clients, as well as the differences between the services that Putnam Management provides to the Putnam funds and those that it provides to institutional clients of the firm, but have not relied on such comparisons to any significant extent in concluding that the management fees paid by your fund are reasonable.

Financial statements

A guide to 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 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 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.

Report of Independent Registered
Public Accounting Firm

To the Trustees and Shareholders of Putnam Massachusetts Tax Exempt Income Fund:

In our opinion, the accompanying statement of assets and liabilities, including the fund’s portfolio, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Putnam Massachusetts Tax Exempt Income Fund (the “fund”) at May 31, 2006, and the results of its operations, the changes in its net assets and the financial highlights for each of the periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of investments owned at May 31, 2006 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

Notes to financial statements 5/31/06

Note 1: Significant accounting policies

Putnam Massachusetts Tax Exempt Income Fund (the “fund”), a Massachusetts business trust, is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company. The fund seeks as high a level of current income exempt from federal income tax and Massachusetts personal income tax as Putnam Investment Management, LLC (“Putnam Management”), the fund’s manager, an indirect wholly-owned subsidiary of Putnam, LLC, believes is consistent with preservation of capital by investing in a portfolio primarily consisting of investment-grade tax exempt securities issued in the state of Massachusetts with intermediate- to long-term maturities. The fund may be affected by economic and political developments in the state of Massachusetts.

The fund offers class A, class B, class C and class M shares. Class A and class M shares are sold with a maximum front-end sales charge of 3.75% and 3.25%, respectively, and generally do not pay contingent deferred sales charges. 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 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.

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.

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 expects the risk of material loss to be remote.

The following is a summary of significant accounting policies consistently followed by the fund in the preparation of its financial statements. The preparation of financial statements is in conformity with accounting principles generally accepted in the United States of America and requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

A) Security valuation Tax-exempt bonds and notes are 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. Other investments are valued at fair value following procedures approved by the Trustees. Such valuations and procedures are reviewed periodically by the Trustees. 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

44

of a security at a given point in time and does not reflect an actual market price.

B) 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.

C) Futures and options contracts The fund may use futures and options contracts to hedge against changes in the values of securities the fund owns or expects to purchase, or for other investment purposes. The fund may also write options on swaps or securities it owns or in which it may invest to increase its current returns.

The potential risk to the fund is that the change in value of futures and options contracts may not correspond to the change in value of the hedged instruments. In addition, losses may arise from changes in the value of the underlying instruments, if there is an illiquid secondary market for the contracts, or if the counterparty to the contract is unable to perform. Risks may exceed amounts recognized on the statement of assets and liabilities. When the contract is closed, the fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Realized gains and losses on purchased options are included in realized gains and losses on investment securities. If a written call option is exercised, the premium originally received is recorded as an addition to sales proceeds. If a written put option is exercised, the premium originally received is recorded as a reduction to the cost of investments.

Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. The fund and the broker agree to exchange an amount of cash equal to the daily fluctuation in the value of the futures contract. Such receipts or payments are known as “variation margin.” Exchange traded options are valued at the last sale price or, if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by dealers. Futures and written option contracts outstanding at period end, if any, are listed after the fund’s portfolio.

D) Interest rate swap contracts The fund may enter into interest rate swap contracts, which are arrangements between two parties to exchange cash flows based on a notional principal amount, to manage the fund’s exposure to interest rates. Interest rate swap contracts are marked to market daily based upon quotations from an independent pricing service or market makers and the change, if any, is recorded as unrealized gain or loss. Payments received or made are recorded as realized gains or loss. The fund could be exposed to credit or market risk due to unfavorable changes in the fluctuation of interest rates or if the counterparty defaults on its obligation to perform. Risk of loss may exceed amounts recognized on the statement of assets and liabilities. Interest rate swap contracts outstanding at period end, if any, are listed after the fund’s portfolio.

E) Federal taxes It is the policy of the fund to distribute all of its income within the prescribed time and otherwise comply with the provisions of the Internal Revenue Code of 1986 (the “Code”) applicable to regulated investment companies. It is also the intention of the fund to distribute an amount sufficient to avoid imposition of any excise tax under Section 4982 of the Code, as amended. Therefore, no provision has been made for federal taxes on income, capital gains or unrealized appreciation on securities held nor for excise tax on income and capital gains.

F) 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

45

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 dividends payable and straddle loss deferrals. 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 May 31, 2006, the fund reclassified $75,175 to decrease undistributed net investment income with a decrease to accumulated net realized losses of $75,175.

The tax basis components of distributable earnings and the federal tax cost as of May 31, 2006 were as follows:

Unrealized appreciation	$ 12,171,257
Unrealized depreciation	(986,910)
	—————————————
Net unrealized appreciation	11,184,347
Undistributed tax-exempt income	472,797
Undistributed long-term gain	105,471
Cost for federal income
tax purposes	$294,376,399

Note 2: Management fee, administrative services and other transactions

Putnam Management is paid for management and investment advisory services quarterly based on the average net assets of the fund. Such fee is based on the lesser of (i) an annual rate of 0.50% of the average net assets of the fund or (ii) the following annual rates expressed as a percentage of the fund’s average net assets: 0.60% of the first $500 million, 0.50% of the next $500 million, 0.45% of the next $500 million, 0.40% of the next $5 billion, 0.375% of the next $5 billion, 0.355% of the next $5 billion, 0.34% of the next $5 billion and 0.33% thereafter.

Putnam Management has agreed to waive fees and reimburse expenses of the fund through May 31, 2007 to the extent necessary to ensure that the fund’s expenses do not exceed the simple average of the expenses of all front-end load funds viewed by Lipper Inc. as having the same investment classification or objective as the fund. The expense reimbursement is based on a comparison of the fund’s expenses with the average annualized operating expenses of the funds in its Lipper peer group for each calendar quarter during the fund’s last fiscal year, excluding 12b-1 fees and without giving effect to any expense offset and brokerage service arrangements that may reduce fund expenses. For the year ended May 31, 2006, Putnam Management did not waive any of its management fee from the fund.

For the year ended May 31, 2006, Putnam Management has assumed $2,140 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. PFTC receives fees for custody services based on the fund’s asset level, the number of its security holdings and transaction volumes. Putnam Investor Services, a division of PFTC, provides investor servicing agent functions to the fund. Putnam Investor Services receives fees for investor servicing based on the number of shareholder accounts in the fund and the level of defined contribution plan assets in the fund. During the year ended May 31, 2006, the fund incurred $251,876 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 May 31, 2006, the fund’s expenses were reduced by $165,977 under these arrangements.

46

Each independent Trustee of the fund receives an annual Trustee fee, of which $304, 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, industry seminars and for certain compliance-related matters. Trustees also are reimbursed for expenses they incur relating to their services as Trustees. George Putnam, III, who is not an independent Trustee, also receives the foregoing fees for his services as Trustee.

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 noncontribu-tory 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. 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, 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% 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% 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% on the net assets of the fund attributable to class A shares purchased and paid for prior to April 1, 2005 and (ii) 0.25% on all other net assets of the fund attributable to class A shares.

For the year ended May 31, 2006, Putnam Retail Management, acting as underwriter, received net commissions of $18,691 and $93 from the sale of class A and class M shares, respectively, and received $88,010 and $1,850 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 that were purchased without an initial sales charge as part of an investment of $1 million or more. For the year ended May 31, 2006, Putnam Retail Management, acting as underwriter, received $638 on class A redemptions.

Note 3: Purchases and sales of securities

During the year ended May 31, 2006, cost of purchases and proceeds from sales of investment securities other than short-term investments aggregated $22,332,829 and $38,841,831, respectively. There were no purchases or sales of U.S. government securities.

Note 5: Regulatory matters and litigation

Putnam Management has entered into agreements with the Securities and Exchange Commission and the Massachusetts Securities Division settling charges connected 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. Pursuant to these settlement agreements, Putnam Management will pay a total of $193.5 million in penalties and restitution, with $153.5 million being paid to certain open-end funds and their shareholders. The amount will be allocated to shareholders and funds pursuant to a plan developed by an independent consultant, and will be paid following approval of the plan by the SEC and the Massachusetts Securities Division.

The Securities and Exchange Commission’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 will bear any costs incurred by Putnam funds in connection with these lawsuits. 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.

Putnam Management and Putnam Retail Management are named as defendants in a civil suit in which the plaintiffs allege that the management and distribution fees paid by certain Putnam funds were excessive and seek recovery under the Investment Company Act of 1940. Putnam Management and Putnam Retail Management have contested the plaintiffs’ claims and the matter is currently pending in the U.S. District Court for the District of Massachusetts. Based on currently available information, Putnam Management believes that this action is without merit and that it is unlikely to have a material effect on Putnam Management’s and Putnam Retail Management’s ability to provide services to their clients, including the fund.

Item 2. Code of Ethics:

(a) The fund’s 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.

(c) In July 2005, Putnam Investment Management, LLC, the Fund's investment manager, Putnam Retail Management Limited Partnership, the Fund's principal underwriter, and Putnam Investments Limited, the sub-manager for a portion of the assets of certain funds as determined by Putnam Management from time to time, adopted several amendments to their Code of Ethics. Insofar as such Code of Ethics applies to the Fund's principal executive officer, principal financial officer and principal accounting officer, the amendments provided for an exception to the standard 90-day holding period (one year, in the case of employees deemed to be “access persons” under the Code) for shares of Putnam mutual funds in the case of redemptions from an employee’s account in a college savings plan qualified under Section 529 of the Internal Revenue Code. Under this exception, an employee may, without penalty under the Code, make “qualified redemptions” of shares from such an account less than 90 days (or one year, as applicable) after purchase. “Qualified redemptions” include redemptions for higher education purposes for the account beneficiary and redemptions made upon death or disability. The July 2005 amendments also provide that an employee may, for purposes of the rule limiting the number of trades per calendar quarter in an employee’s personal account to a maximum of 10, count all trades of the same security in the same direction (all buys or all sells) over a period of five consecutive business days as a single trade.

The July 2005 amendments were incorporated into a restated Code of Ethics dated December 2005 (filed as an exhibit hereto).

Item 3. Audit Committee Financial Expert:

The Funds' Audit and Compliance 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 Compliance 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 Compliance Committee meet the financial literacy requirements of the New York Stock Exchange's rules and that Mr. Patterson, Mr. Stephens and Mr. Hill 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 Compliance 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 Compliance Committee and the Board of Trustees in the absence of such designation or identification.

Item 4. Principal Accountant Fees and Services:

The following table presents fees billed in each of the last two fiscal years for services rendered to the fund by the fund’s independent auditor:

Fiscal		Audit-
year	Audit	Related	Tax	All Other
ended	Fees	Fees	Fees	Fees
May 31, 2006	$44,704*	$--	$6,798	$ -
May 31, 2005	$40,336*	$--	$6,463	$24

* Includes fees of $ 191 and $ 9 billed by the fund’s independent auditor to the fund for audit procedures necessitated by regulatory and litigation matters for the fiscal years ended May 31, 2006 and May 31, 2005, respectively. These fees were reimbursed to the fund by Putnam Investment Management, LLC (“Putnam Management”).

For the fiscal years ended May 31, 2006 and May 31, 2005, the fund’s independent auditor billed aggregate non-audit fees in the amounts of $238,572 and $188,600 respectively, to the fund, Putnam Management and any entity controlling, controlled by or under common control with Putnam Management that provides ongoing services to the fund.

Audit Fees represent fees billed for the fund’s last two fiscal years.

Audit-Related Fees represent fees billed in the fund’s last two fiscal years for services traditionally performed by the fund’s auditor, including accounting consultation for proposed transactions or concerning financial accounting and reporting standards and other audit or attest services not required by statute or regulation.

Tax Fees represent fees billed in the fund’s last two fiscal years for tax compliance, tax planning and tax advice services. Tax planning and tax advice services include assistance with tax audits, employee benefit plans and requests for rulings or technical advice from taxing authorities.

All Other Fees represent fees billed for services relating to an analysis of recordkeeping fees.

Pre-Approval Policies of the Audit and Compliance Committee. The Audit and Compliance 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 itself and thus will generally not be subject to pre-approval procedures.

The Audit and Compliance Committee also has adopted a policy to pre-approve the engagement by Putnam Management and certain of its affiliates of the funds’ independent auditors, even in circumstances where pre-approval is not required by applicable law. Any such requests by Putnam Management or certain of its affiliates are typically submitted in writing to the Committee and explain, among other things, the nature of the proposed engagement, the estimated fees, and why this work should be performed by that particular audit firm as opposed to another one.

The following table presents fees billed by the fund’s independent auditor for services required to be approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X.

Fiscal	Audit-		All	Total
year	Related	Tax	Other	Non-Audit

                             THE PUTNAM FUNDS

                              Code of Ethics

Each of The Putnam Funds (the "Funds") has determined to adopt this Code
of Ethics with respect to certain types of personal securities
transactions by officers and Trustees of the Funds which might be deemed
to create possible conflicts of interest and to establish reporting
requirements and enforcement procedures with respect to such
transactions.

I. Rules Applicable to Officers and Trustees Affiliated with Putnam
Investments Trust or Its Subsidiaries

A. Incorporation of Adviser's Code of Ethics.  The provisions of the
Code of Ethics for employees of Putnam Investments Trust and its
subsidiaries (the "Putnam Investments Code of Ethics"), which is
attached as Appendix A hereto, are hereby incorporated herein as the
Funds' Code of Ethics applicable to officers and Trustees of the Funds
who are employees of the Funds or officers, directors or employees of
Putnam Investments Trust or its subsidiaries.  A violation of the Putnam
Investments' Code of Ethics shall constitute a violation of the Funds'
Code.

B. Reports.  Officers and Trustees of each of the Funds who are made
subject to the Putnam Investments' Code of Ethics pursuant to the
preceding paragraph shall file the reports required by the Putnam
Investments' Code of Ethics with the Code of Ethics Officer designated
therein.  A report filed with the Code of Ethics Officer shall be deemed
to be filed with each of the Funds of which the reporting individual is
an officer or Trustee.

C. Review and Reporting.

(1) The Code of Ethics Officer shall cause the reported personal
securities transactions to be compared with completed and contemplated
portfolio transactions of each of the Funds to determine whether a
violation of this Code may have occurred.  Before making any
determination that a violation has been committed by any person, the
Code of Ethics Officer shall give such person an opportunity to supply
additional explanatory material.

(2) If the Code of Ethics Officer determines that a violation of any
provision of this Code has or may have occurred, he shall submit his
written determination, together with any additional explanatory
material, to the Audit and Pricing Committee of the Funds at its next
meeting.

D. Sanctions.  In addition to reporting violations of this Code to the
Audit and Pricing Committee of the Funds as provided in Section I-C(2),
the Code of Ethics officer shall also report to such Committee any
sanctions imposed with respect to such violations.  The Committee
reserves the right to impose such additional sanctions as it deems
appropriate.

II. Rules Applicable to Unaffiliated Trustees

A. Definitions.

(1) "Beneficial ownership" shall be interpreted in the same manner as it
would be in determining whether a person is subject to the provisions of
Section 16 of the Securities Exchange Act of 1934 and the rules and
regulations thereunder.

(2) "Control" means the power to exercise a controlling influence over
the management or policies of a company, unless such power is solely the
result of an official position with such company.

(3) "Interested Trustee" means a Trustee of a Fund who is an "interested
person" of the Fund within the meaning of the Investment Company Act.

(4) "Purchase or sale of a security" includes, among other things, the
writing of an option to purchase or sell a security.

(5) "Security" shall have the same meaning as that set forth in Section
2(a)(36) of the Investment Company Act (in effect, all securities)
except that it shall not include securities issued by the Government of
the United States or an agency thereof, bankers' acceptances, bank
certificates of deposit, commercial paper and high-quality short-term
debt investments, including repurchase agreements, and shares of
registered open-end investment companies, but shall include any security
convertible into or exchangeable for a security.

(6) "Unaffiliated Trustee" means a Trustee who is not made subject to
the Putnam Investments Code of Ethics pursuant to Part I hereof.

B. Prohibited Purchases and Sales.  No Unaffiliated Trustee of any of
the Funds shall purchase or sell, directly or indirectly, any security
in which he has, or by reason of such transaction acquires, any direct
or indirect beneficial ownership and which to his actual knowledge at
the time of such purchase or sale:

(1) is being considered for purchase or sale by the Fund;

(2) is being purchased or sold by the Fund; or

(3) was purchased or sold by the Fund within the most recent five days
if such person participated in the recommendation to, or the decision
by, Putnam Investment Management to purchase or sell such security for
the Fund.

C. Exempted Transactions.  The prohibitions of Section II-B of this Code
shall not apply to:

(1) purchases or sales of securities effected in any account over which
the Unaffiliated Trustee has no direct or indirect influence or control;

(2) purchases or sales of securities which are non-volitional on the
part of either the Unaffiliated Trustee or the Fund;

(3) purchases of securities which are part of an automatic dividend
reinvestment plan;

(4) purchases of securities effected upon the exercise of rights issued
by an issuer pro rata to all holders of a class of its securities, to
the extent such rights were acquired from such issuer, and sales of such
rights so acquired;

(5) purchases or sales of securities other than those exempted in (1)
through (4) above which do not cause the Unaffiliated Trustee to gain
improperly a personal benefit through his relationship with the Fund and
are only remotely potentially harmful to a Fund because they would be
very unlikely to affect a highly institutional market, and are
previously approved by the Legal and Compliance Liaison Officer of the
Funds, in consultation with the Code of Ethics Officer, which approval
shall be confirmed in writing.

D. Reporting.

(1) Whether or not one of the exemptions listed in Section II-C applies
and except as provided in Section II-C(5), every Unaffiliated Trustee of
a Fund shall file with the Funds' Legal and Compliance Liaison Officer a
report containing the information described in Section II-D(2) of this
Code with respect to purchases or sales of any security in which such
Unaffiliated Trustee has, or by reason of such transaction acquires, any
direct or indirect beneficial ownership, if such Trustee, at the time of
that transaction, knew or, in the ordinary course of fulfilling his
official duties as a Trustee of the Fund, should have known that, during
the 15-day period immediately preceding or after the date of the
transaction by the Trustee:

(a) such security was or is to be purchased or sold by the Fund or

(b) such security was or is being considered for purchase or sale by the
Fund;

provided, however, that an Unaffiliated Trustee shall not be required to
make a report with respect to transactions effected for any account over
which such person does not have any direct or indirect influence or
control.

(2) Every report shall be made not later than 10 days after the end of
the calendar quarter in which the transaction to which the report
relates was effected, and shall contain the following information:

(a) The date of the transaction, the title, the number of shares, the
interest rate and maturity date (if applicable) and the principal amount
of each security involved;

(b) The nature of the transaction (i.e., purchase, sale or any other
type of acquisition or disposition);

(c) The price at which the transaction was effected; and

(d) The name of the broker, dealer or bank with or through whom the
transaction was effected; and

(e) the date that the report is submitted by each Unaffiliated Trustee.

(3) Every report concerning a purchase or sale prohibited under Section
II-B hereof with respect to which the reporting person relies upon one
of the exemptions provided in Section II-C shall contain a brief
statement of the exemption relied upon and the circumstances of the
transaction.

(4) Any such report may contain a statement that the report shall not be
construed as an admission by the person making such report that he has
any direct or indirect beneficial ownership in the security to which the
report relates.

(5) Notwithstanding anything to the contrary contained herein, an
Unaffiliated Trustee who is an "interested person" of the Funds shall
file the reports required by Rule 17j-1(d)(1) under the Investment
Company Act of 1940 with the Code of Ethics Officer of Putnam
Investments.  Such reports shall be reviewed by such Officer as provided
in Section I-C(1) and any related violations shall be reported by him to
the Audit and Pricing Committee as provided in Section I-C(2).  The
Committee may impose such additional sanctions as it deems appropriate.

E. Review and Reporting.

(1) The Legal and Compliance Liaison Officer of the Funds, in
consultation with the Code of Ethics Officer of Putnam Investments,
shall cause the reported personal securities transactions that he
receives pursuant to Section II-D(1) to be compared with completed and
contemplated portfolio transactions of the Funds to determine whether
any transaction ("Reviewable Transactions") listed in Section II-B
(disregarding exemptions provided by Section II-C(1) through (5)) may
have occurred.

(2) If the Legal and Compliance Liaison Officer determines that a
Reviewable Transaction may have occurred, he shall then determine
whether a violation of this Code may have occurred, taking into account
all the exemptions provided under Section II-C.  Before making any
determination that a violation has occurred, the Legal and Compliance
Liaison Officer shall give the person involved an opportunity to supply
additional information regarding the transaction in question.

F. Sanctions.  If the Legal and Compliance Liaison determines that a
violation of this Code has occurred, he shall so advise the Funds' Audit
and Pricing Committee, and provide the Committee with a report of the
matter, including any additional information supplied by such person.
The Committee may impose such sanctions as it deems appropriate.

III. Miscellaneous

A. Amendments to the Putnam Investments' Code of Ethics.  Any amendment
to the Putnam Investments' Code of Ethics shall be deemed an amendment
to Section I-A of this Code effective 30 days after written notice of
such amendment shall have been received by the Chairman of the Funds,
unless the Trustees of the Funds expressly determine that such amendment
shall become effective at an earlier or later date or shall not be
adopted.

B. Records.  The Funds shall maintain records in the manner and to the
extent set forth below, which records may be maintained on microfilm
under the conditions described in Rule 31a-2(f)(1) under the Investment
Company Act and shall be available for examination by representatives of
the Securities and Exchange Commission.

(1) A copy of this Code and any other code which is, or at any time
within the past five years has been, in effect shall be preserved in an
easily accessible place;

(2) A record of any violation of this Code and of any action taken as a
result of such violation shall be preserved in an easily accessible
place for a period of not less than five years following the end of the
fiscal year in which the violation occurs;

(3) A copy of each report made by an officer or Trustee pursuant to this
Code shall be preserved for a period of not less than five years from
the end of the fiscal year in which it is made, the first two years in
an easily accessible place; and

(4) A list of all persons who are, or within the past five years have
been, required to make reports pursuant to this Code shall be maintained
in an easily accessible place.

To the extent any record required to be kept by this section is also
required to be kept by Putnam Investments pursuant to the Putnam
Investments' Code of Ethics, Putnam Investments shall maintain such
record on behalf of the Funds as well.

C. Confidentiality.  All reports of securities transactions and any
other information filed with any Fund pursuant to this Code shall be
treated as confidential, but are subject to review as provided herein
and by personnel of the Securities and Exchange Commission.

D. Interpretation of Provisions.  The Trustees may from time to time
adopt such interpretations of this Code as they deem appropriate.

E. Delegation by Chairman.  The Chairman of the Funds may from time to
time delegate any or all of his responsibilities under this Code, either
generally or as to specific instances, to such officer or Trustee of the
Funds as he may designate.
