What makes Putnam different?

[GRAPHIC OMITTED: FOUNDER]

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.

Message from the Trustees

Dear Fellow Shareholder

During the period ended July 31, 2005, the stock market has continued to
show confidence in the strength of the economy and corporate profits, even
as the Federal Reserve Board's more restrictive monetary policy, along
with high energy prices, has begun to influence the performance of bonds
and the pace of expansion. Abroad, stocks have performed even better than
in the United States, despite weaker economic growth in most developed
markets. However, the recent strength of the U.S. dollar against foreign
currencies partially offset the effects of these gains. And in the last
three weeks, investors have just begun to assess the magnitude of
Hurricane Katrina's impact and how it will affect the U.S. economy. Amid
the uncertainties of this environment, the in-depth, professional research
and active management that mutual funds can provide make them an
intelligent choice for today's investors.

We want you to know that 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 keeping with these goals, we have redesigned and
expanded our shareholder reports to make it easier for you to learn more
about your fund. Furthermore, on page 24 we provide information about the
2005 approval by the Trustees of your fund's management contract with
Putnam.

We would also like to take this opportunity to announce the retirement of
one of your fund's Trustees, Ronald J. Jackson, who has been an
independent Trustee of the Putnam funds since 1996. We thank him for his
service.

In the following pages, members of your fund's management team discuss the
fund's performance, strategies, and their outlook for the months ahead. As
always, we thank you for your support of the Putnam funds.

Respectfully yours,

/S/GEORGE PUTNAM, III

Putnam AMT-Free Insured Municipal Fund: seeking high current income free
from federal taxes

[GRAPHIC OMITTED: IRS FORM]

IRS Form 6251 for the AMT may become as familiar as Form 1040.

Municipal bonds have long been popular investments because they provide
income exempt from federal taxes, though capital gains are taxable. With
Putnam AMT-Free Insured Municipal Fund, you get income exempt from
traditional income tax as well as from the alternative minimum tax, or
AMT.

The AMT is a federal tax that operates in parallel with the regular income
tax system. Taxpayers subject to the AMT must pay a larger amount in tax
determined by AMT rules -- and the difference can be thousands of dollars
for many with household incomes above $150,000. It is estimated that by
2010, nearly every household with income of $100,000 or more will be
paying the AMT, unless the federal government changes the law.

If you are subject to the AMT, investments that could increase your tax
liability include private-activity municipal bonds, which back development
projects such as housing and resource recovery projects.

Putnam AMT-Free Insured Municipal Fund aims to serve investors subject to
the AMT. The fund seeks to avoid bonds whose income would be taxable under
AMT rules, though income may be subject to state taxes.

The fund's portfolio team of four professionals, with a combined 55 years of
experience, researches the municipal market to avoid buying bonds subject to
the AMT. Pursuing the fund's mandate, they also keep the fund invested in
high-quality bonds, favoring bonds that are insured or carry AAA ratings, or
whose payments are backed by U.S. Treasuries. The team's goal is to provide
an attractive level of income exempt from all federal taxes.

Mutual funds that invest in bonds are subject to certain risks, including
interest-rate risk, credit risk, and inflation risk. As interest rates
rise, the prices of bonds fall. Long-term bonds are more exposed to
interest-rate risk than short-term bonds. Unlike bonds, bond funds have
ongoing fees and expenses. Income from federally exempt funds may be
subject to state and local taxes. Tax-free funds may not be suitable for
IRAs and other non-taxable accounts. Shares of this fund are not insured,
and their prices will fluctuate with market conditions.

Understanding the AMT

The AMT is a separate, parallel federal income tax system, with two
marginal tax rates, 26% and 28%, and different exemption amounts.

Under AMT rules, certain exclusions, exemptions, deductions, and credits
that would reduce your regular taxable income are not allowed. You must
"adjust" your regular taxable income to arrive at your alternative minimum
taxable income (AMTI). Then, after subtracting your AMT exemption amount,
if your AMT liability is greater than your regular tax liability, you must
pay both your regular tax and the difference. It's important to understand
that a higher level of income will not necessarily cause you to owe AMT.
Rather, it is the relationship between your income and various trigger
items, such as credits and deductions, that determines your AMT liability.

Managing this relationship can help avoid a costly surprise at tax time.
Any number of items may trigger the tax, but large capital gains, personal
exemptions, and deductions are the worst culprits.

as to timely payment of principal and interest, escrowed by securities
guaranteed by the U.S. government, and/or bonds that are rated AAA (or the
equivalent), which is the highest credit rating available. The fund is
intended and may be appropriate for investors seeking high current income
free from federal income tax.

Report from the fund managers

The year in review

Your fund's performance benefited from the pre-refunding of several
holdings during its fiscal year, which helped the fund perform in line
with the average for its Lipper category. However, the fund underperformed
its benchmark for the period, due in part to its defensive duration
position. Duration is a measure of sensitivity to changes in interest
rates, and we had shortened it to protect the fund in anticipation of
rising rates. While short-term rates did rise, long-term rates fell so the
positioning was not as beneficial as we had hoped. In addition, the fund's
benchmark includes securities from the lower tiers of the investment-grade
universe (down to Baa), while your fund invests in the highest-rated
securities. Lower-rated bonds significantly outperformed higher-rated
bonds for the period.

Market overview

Signs of accelerating economic growth and rising corporate profits
prompted the Federal Reserve Board (the Fed) to increase the federal funds
rate eight times during the 12 months ended July 31, 2005, in gradual
increments of 0.25%. The Fed uses interest-rate increases in an effort to
rein in economic growth and limit inflationary pressures. However, while
yields on shorter-term securities rose in response to the Fed's moves,
yields on longer-term bonds trended downward, causing a flattening of the
yield curve as rates on both ends of the spectrum converged.

The same conditions that prompted the Fed to raise short-term interest
rates -- an improving economy and rising corporate earnings -- were
favorable for lower-rated bonds. With bond yields generally at
historically low levels, and confidence buoyed by the growing economy,
investors sought out lower-quality bonds, which typically carry higher
yields because of their greater credit risk. Bonds at the lower end of the
credit spectrum, including Ba- and B-rated bonds, turned in the strongest
performance. Among uninsured bonds, and especially bonds rated Baa and
below, yield spreads tightened, and bond prices rose. Certain sectors were
also stronger than others. Based on continued favorable legal rulings,
yields on tobacco settlement bonds generally declined during the period,
and their prices rose accordingly. After underperforming earlier in the
year, airline-related industrial development bonds (IDBs) staged a
comeback from distressed levels and outperformed over the trailing
six-month period. Callable bonds (which can be redeemed by their issuers
before maturity) outperformed non-callable bonds, as investors expect
these bonds to be less sensitive to interest rate increases.

Strategy overview

Given our expectation for rising interest rates, your fund's portfolio
duration was relatively short, or defensive. Investing in bonds with short
duration may help protect principal when interest rates are rising, but it
can reduce the fund's potential for appreciation when rates fall. As we
had expected, the Fed increased short-term interest rates during the
period. However, rates on long-term bonds unexpectedly trended downward,
and the prices of these bonds rose as a result. Thus, the fund's
participation in this rally was limited by its defensive duration
position.

During the period, we positioned the fund to take advantage of the
flattening of the yield curve. To accomplish this we sold bonds with short
maturities and purchased those with longer maturities. We also entered into
swap agreements, an active strategy in which we swapped a portion of the
fixed interest payments received by the fund for floating-rate interest
payments. This approach allowed us to reduce exposure to shorter-term
securities, which were declining in price as short-term rates increased, and
to focus more on longer maturities.

- ------------------------------------------------------------------------------

The fund also benefited from our preference for bonds issued to fund new
projects versus bonds issued to refinance existing projects. The benefit of
owning "new money" bonds is that they can be pre-refunded -- an action that
generally results in a rise in credit quality and price. Bonds issued after
1986 cannot be advance refunded more than once per the Tax and Equity
Fiscal Responsibility Act of 1982 (TEFRA). We also increased the fund's
exposure to the single-family housing sector during the period, as we
expect this sector to outperform.

Your fund's holdings

Duration management and yield curve positioning are two key strategies we
use to pursue your fund's objectives. Duration management is positioning
the portfolio to benefit from falling, or protect it from rising, interest
rates. Yield curve positioning involves adjusting the portfolio for
flattening, steepening, or some other expected shift in the yield curve.
Sector and security selection are two other important tools used by your
fund's management team.

Comparison of the fund's maturity and duration

[GRAPHIC OMITTED: bar chart COMPARISON OF THE FUND'S MATURITY AND DURATION]

This chart compares changes in the fund's duration (a measure of its
sensitivity to interest-rate changes) and its average effective maturity
(a weighted average of the holdings' maturities).

                           as of 7/31/04  as of 1/31/2005   as of 7/31/2005

Average effective
maturity in years                7.3            6.4               6.8

Duration in years                5.4            5.1               5.1

Footnote reads:
Average effective maturity also takes into account put and call features,
where applicable, and reflects prepayments for mortgage-backed securities.


As discussed in the strategy section, we increased the fund's holdings in
the single-family housing sector because we expect that this sector will
outperform as rising interest rates should result in falling mortgage
prepayment rates. During the period, we initiated a $2 million position in
single-family mortgage bonds issued by Hawaii State Housing & Community
Development Authority. As with any mortgage-backed security, this purchase
involved extensive analysis of the cash flows of the underlying mortgages
to assess and manage prepayment risk.

A preference for "new money" issues is another key element of our
strategy. This strategy proved its worth during the period as, on an
issue-specific basis, the fund benefited most from the pre-refunding of
several bonds held in its portfolio. Pre-refunding occurs when an issuer
raises money to refinance an older, higher-coupon bond by issuing new
bonds at current lower interest rates. This money is then invested in a
secure investment, usually U.S. Treasury securities, that mature at the
older bond's first call date, when it is used to pay off the old bonds.

Among Aaa-rated insured issues, which make up a significant portion of the
portfolio, the primary driver behind price appreciation in a pre-refunding
is the shortening of the bond's time to maturity. Pre-refunded bonds are
being priced to a shorter point on the yield curve, which results in a
lower yield and a higher bond price.

Credit quality overview

Credit qualities shown as a percentage of portfolio value as of 7/31/05. A
bond rated Baa or higher is considered investment grade. The chart

Ratings will vary over time.

[GRAPHIC OMITTED: pie chart CREDIT QUALITY OVERVIEW]

Three of the top five contributors to performance for the fiscal year were
bonds that significantly appreciated in value as a result of
pre-refunding.

In July 2005, FGIC-insured Massachusetts State Special Obligation Dedicated
Tax revenue bonds were pre-refunded. These bonds, which had original
maturity dates ranging from 2022 to 2024, were pre-refunded to 2014.
Similarly, in June 2005, FGIC-insured revenue bonds issued by the New Jersey
Economic Development Authority were pre-refunded to 2013. This issue had an
original maturity date of 2021. Finally, in April 2005, AMBAC-insured
revenue bonds issued by the Center Grove Building Corporation in Indiana
were pre-refunded to July 2011. These bonds had an original maturity date of
2026.

Please note that all holdings discussed in this report are subject to
review in accordance with the fund's investment strategy and may vary in
the future.


- ------------------------------------------------------------------------------
The outlook for your fund

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

Based on sustained economic growth, we expect the Fed to continue to raise
interest rates through 2005, a policy that will likely lead to rising bond
yields. We also expect more Fed tightening than is currently anticipated
by the market, and believe that bond yields may begin to rise more quickly
as other investors come to the same conclusion.

In light of current market conditions, we plan to maintain the fund's
defensive duration and to continue to increase its exposure to callable
bonds, which, in our opinion, are likely to outperform in a rising-rate
cycle. We have a positive view of the single-family housing sector and
plan to add selectively to the fund's positions.

We will continue to search for the most attractive opportunities among
insured, AAA-rated tax-exempt securities, and to balance the pursuit of
current income with prudent risk management.

The views expressed in this report are exclusively those of Putnam
Management. They are not meant as investment advice. Capital gains, if
any, are taxable for federal and, in most cases, state purposes. For some
investors, investment income may be subject to the federal alternative
minimum tax. Income from federally exempt funds may be subject to state
and local taxes. Mutual funds that invest in bonds are subject to certain
risks, including interest-rate risk, credit risk, and inflation risk. As
interest rates rise, the prices of bonds fall. Long-term bonds are more
exposed to interest-rate risk than short-term bonds. Unlike bonds, bond
funds have ongoing fees and expenses. Tax-free funds may not be suitable
for IRAs and other non-taxable accounts. Shares of this fund are not
insured, and their prices will fluctuate with market conditions.

indicated, returns would have been higher). 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 A, C, and M shares before
their inception is derived from the historical performance of class B
shares, adjusted for the applicable sales charge (or CDSC) and higher or
lower operating expenses for such shares.

For a portion of the period, this fund limited expenses, without which
returns would have been lower.

A 2% short-term trading fee may be applied to shares exchanged or sold
within 5 days of purchase.

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. In the most
recent six-month period, your fund limited these expenses; had it not done
so, expenses would have been higher. Using the information below, you can
estimate how these expenses affect your investment and compare them with
the expenses of other funds. You may also pay one-time transaction
expenses, including sales charges (loads) and redemption fees, which are
not shown in this section and would have resulted in higher total
expenses. For more information, see your fund's prospectus or talk to your
financial advisor.

- ------------------------------------------------------------------------------
Review your fund's expenses

The table below shows the expenses you would have paid on a $1,000
investment in Putnam AMT-Free Insured Municipal Fund from February 1,
2005, to July 31, 2005. It also shows how much a $1,000 investment would
be worth at the close of the period, assuming actual returns and expenses.

- ------------------------------------------------------------------------------

* 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 7/31/05.
  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 July
31, 2005, use the calculation method below. To find the value of your

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.

* 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 7/31/05.
  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.

- ------------------------------------------------------------------------------
Compare expenses using industry averages

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.

 + 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 6/30/05. 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 data for the fund is calculated based on the fund's fiscal-year
period, which ends on July 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 2005 is based on information available as of 6/30/05.


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.

- ------------------------------------------------------------------------------

Fund's Overall
Morningstar Risk       0.22

Municipal bond
fund average           0.20

0%   INCREASING RISK   100%

Your fund's Overall Morningstar Risk is shown alongside that of the
average fund in its broad asset class, as determined by Morningstar. The
risk bar broadens the comparison by translating the fund's Overall
Morningstar Risk into a percentile, which is based on the fund's ranking
among all funds rated by Morningstar as of June 30, 2005. A higher Overall
Morningstar Risk generally indicates that a fund's monthly returns have
varied more widely.

Morningstar determines a fund's Overall Morningstar Risk by assessing
variations in the fund's monthly returns -- with an emphasis on downside
variations -- over 3-, 5-, and 10-year periods, if available. Those
measures are weighted and averaged to produce the fund's Overall
Morningstar Risk. The information shown is provided for the fund's class A
shares only; information for other classes may vary. Overall Morningstar
Risk is based on historical data and does not indicate future results.
Morningstar does not purport to measure the risk associated with a current
investment in a fund, either on an absolute basis or on a relative basis.
Low Overall Morningstar Risk does not mean that you cannot lose money on
an investment in a fund. Copyright 2004 Morningstar, Inc. All Rights

Fund manager compensation

The total 2004 fund manager compensation that is attributable to your fund
is approximately $100,000. This amount includes a portion of 2004
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 2004
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 2004, the calculation reflects
annualized 2004 compensation or an estimate of 2005 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 4.50% maximum sales charge for class A
shares (since reduced to 3.75%) and 3.25% for class M shares.

Contingent deferred sales charge (CDSC) is a charge applied at the time of
the redemption of class B or C shares and assumes redemption at the end of
the period. Your fund's class B CDSC declines from a 5% maximum during the
first year to 1% during the sixth year. After the sixth year, the CDSC no
longer applies. The CDSC for class C shares is 1% for one year after
purchase.

- ------------------------------------------------------------------------------
Share classes

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

Class B shares may be subject to a sales charge upon redemption.

Class C shares are not subject to an initial sales charge and are subject
to a contingent deferred sales charge only if the shares are redeemed
during the first year.

Class M shares have a lower initial sales charge and a higher 12b-1 fee
than class A shares and no sales charge on redemption (except on certain
redemptions of shares bought without an initial sales charge).

- ------------------------------------------------------------------------------
Comparative indexes

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

Lehman Global Aggregate Bond Index is an unmanaged index of global
investment-grade fixed-income securities.

Lehman GNMA Index is an unmanaged index of Government National Mortgage
Association bonds.

Lehman Municipal Bond Index is an unmanaged index of long-term fixed-rate

Indexes assume reinvestment of all distributions and do not account for
fees. Securities and performance of a fund and an index will differ. You
cannot invest directly in an index.

Lipper is a third-party industry ranking entity that ranks funds (without
sales charges) with similar current investment styles or objectives as

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.

- ------------------------------------------------------------------------------
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 advisers. 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 currently
  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, has 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 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 in formation 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 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 performance at net asset value was in the following percentiles of
its Lipper Inc. peer group (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
- ------------------------------------------------------------------------------
                   40th                   32nd                 30th

(Because of the passage of time, these performance results may differ from
the performance results for more recent periods shown elsewhere in this
report.)

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 adviser 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 adviser. 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 net assets allocated to
remarketed preferred shares.)

Statement of operations shows the fund's net investment gain or loss. This
is done by first adding up all the fund's earnings -- from dividends and
interest income -- and subtracting its operating expenses to determine net
investment income (or loss). Then, any net gain or loss the fund realized
on the sales of its holdings -- as well as any unrealized gains or losses
over the period -- is added to or subtracted from the net investment result
to determine the fund's net gain or loss for the fiscal year.

Statement of changes in net assets shows how the fund's net assets were
affected by the fund's net investment gain or loss, by distributions to
shareholders, and by changes in the number of the fund's shares. It lists
distributions and their sources (net investment income or realized capital
gains) over the current reporting period and the most recent fiscal
year-end. The distributions listed here may not match the sources listed
in the Statement of operations because the distributions are determined on
a tax basis and may be paid in a different period from the one in which
they were earned.

Financial highlights provide an overview of the fund's investment results,
per-share distributions, expense ratios, net investment income ratios,
and portfolio turnover in one summary table, reflecting the five most
recent reporting periods. In a semiannual report, the highlight table also
includes the current reporting period. For open-end funds, a separate
table is provided for each share class.

Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of
Putnam AMT-Free Insured Municipal 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 AMT-Free
Insured Municipal Fund, formerly Putnam Tax-Free Insured Fund, (the
"fund") at July 31, 2005, 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 July 31, 2005, by correspondence with the custodian and brokers,
provide a reasonable basis for our opinion.

Notes to financial statements 7/31/05

Note 1: Significant accounting policies

Putnam AMT-Free Municipal Fund (the "fund") formerly Putnam Tax-Free
Insured Fund, is a series of Putnam Tax Free Income Trust (the "trust"), a
Massachusetts business trust, which is registered under the Investment
Company Act of 1940, as amended, as a diversified, open end management
investment company. The fund pursues its objective of seeking high current
income exempt from federal income tax by investing in tax exempt
securities that are covered by insurance guaranteeing the timely payment
of principal and interest, are rated AAA or Aaa, or are backed by the U.S.
government.

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 do not pay contingent deferred sales charges.
Prior to April 1, 2005, the maximum front-end sales charge for class A
shares was 4.50%. 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 are subject to the
same fees as class B shares, except that 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 each class' distribution fee, 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 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.

B) Security transactions and related investment income Security
transactions are recorded on the trade date (date the order to buy or sell
is executed). Gains or losses on securities sold are determined on the
identified cost basis.

Interest income is recorded on the accrual basis. All premiums/discounts
are amortized/accreted on a yield-to-maturity basis. The premium in excess
of the call price, if any, is amortized to the call date; thereafter, any
remaining premium is amortized to maturity.

Securities purchased or sold on a forward commitment basis may be settled
a month or more after the trade date; interest income is accrued based on
the terms of the securities. Losses may arise due to changes in the market
value of the underlying securities or if the counterparty does not perform
under the contract.

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

The potential risk to the fund is that the change in value of futures and
options contracts may not correspond to the change in value of the hedged
instruments. In addition, losses may arise from changes in the value of
the underlying instruments, if there is an illiquid secondary market for
the contracts, or if the counterparty to the contract is unable to
perform. 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 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 least annually. The
amount and character of income and gains to be distributed are determined
in accordance with income tax regulations which may differ from generally
accepted accounting principles. These differences include temporary and
permanent differences of losses on wash sales transactions, dividends
payable, realized and unrealized gains and losses on certain futures
contracts 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 July 31, 2005, the fund reclassified $821
to decrease undistributed net investment income with a decrease to
accumulated net realized losses of $821.

The tax basis components of distributable earnings and the federal tax
cost as of period end were as follows:

Unrealized appreciation           $22,897,738
Unrealized depreciation              (385,779)
                                  -----------
Net unrealized appreciation        22,511,959
Undistributed tax exempt
income                                698,375
Undistributed short-term gain         680,303
Undistributed long-term gain          520,094
Cost for federal income tax
purposes                         $354,360,316

G) 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

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 asset
value of the fund or (ii) the following annual rates: 0.60% of the first
$500 million of average net assets, 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 July 31, 2006 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 July 31,
2005, Putnam Management waived $6,111 of its management fee from the fund.

For the period ended July 31, 2005 Putnam Management has assumed $9,201 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 July 31, 2005,
the fund paid PFTC $370,478 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 July 31, 2005, the
fund's expenses were reduced by $37,647 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $289, 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. 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 noncontributory defined benefit pension
plan (the "Pension Plan") covering all Trustees of the fund who have
served as a Trustee for at least five years. Benefits under the Pension
Plan are equal to 50% of the Trustee's average total retainer and meeting
fees for the three years preceding retirement. Pension expense for the
fund is included in Trustee compensation and expenses in the statement of
operations. Accrued pension liability is included in Payable for Trustee
compensation and expenses in the statement of assets and liabilities. The
Trustees have terminated the Pension Plan with respect to any Trustee
first elected after 2003.

The fund has adopted distribution plans (the "Plans") with respect to its
class A, class B, class C 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

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 shareholders and the funds. The restitution amount will be
allocated to shareholders pursuant to a plan developed by an independent
consultant, with payments to shareholders 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 Investments has recorded a charge of $30 million for the estimated
cost, excluding interest, that it believes will be necessary to address
issues relating to the calculation of certain amounts paid by the Putnam
mutual funds in previous years. The previous payments were cost
reimbursements by the Putnam funds to Putnam for transfer agent services
relating to defined contribution operations. Putnam currently anticipates
that any payments made by Putnam related to this issue will be paid to the
Putnam funds. Review of this issue is ongoing.

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.


Federal tax information (Unaudited)

The fund has designated 100% of dividends paid from net investment income
during the fiscal year as tax exempt for federal income tax purposes.

Pursuant to Section 852 of the Internal Revenue Code, as amended, the fund
hereby designates $1,811,838 as long-term capital gain for its taxable
year ended July 31, 2005.

The Form 1099 you receive in January 2006 will show the tax status of all
distributions paid to your account in calendar 2005.

Item 2. Code of Ethics:
- -----------------------
(a) All officers of the Fund, including its principal executive, financial and
accounting officers, are employees of Putnam Investment Management, LLC,
the Fund's investment manager.  As such they are subject to a comprehensive
Code of Ethics adopted and administered by Putnam Investments which is
designed to protect the interests of the firm and its clients.  The Fund
has adopted a Code of Ethics which incorporates the Code of Ethics of
Putnam Investments with respect to all of its officers and Trustees who are
employees of Putnam Investment Management, LLC.  For this reason, the Fund
has not adopted a separate code of ethics governing its principal
executive, financial and accounting officers.

(c) In July 2004, 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.  Some of these
amendments were adopted as a result of Putnam Investment Management's
partial settlement order with the SEC on November 13, 2003.  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 the following:  (i) a 90-day blackout period for all shares of Putnam
open-end funds (except for money market funds) purchased or sold (including
exchanges into or out of a fund) by Putnam employees and certain family
members; (ii) a one-year holding period for all access persons that operates
in the same manner as the 90-day rule; (iii) delivery by Putnam employees to
the Code of Ethics Administrator of both quarterly account statements for
all brokerage accounts (irrespective of activity in the accounts) and
account statements for any Putnam funds not held at Putnam or for any funds
sub-advised by Putnam; (iv) a prohibition of Putnam employees from making
more than 25 trades in individual securities in their personal accounts in
any given quarter; (v) the extension of the existing prohibition of access
persons from a purchase and sale or sale and purchase of an individual
security within 60 days to include trading based on tax-lot election; (vi)
the inclusion of trades in Marsh & McLennan Companies, Inc. (ultimate parent
company of Putnam Investment Management) securities in pre-clearance and
reporting requirements; (vii) a prohibition of limit and good-until-canceled
orders as inconsistent with the requirements of daily pre-clearance; (viii)
new limits and procedures for accounts managed by outside managers and
brokers, in order for trading in such accounts to be exempt from
pre-clearance requirements; (ix) a new gift and entertainment policy that
imposes a reporting obligation on all meals and entertainment and new limits
on non-meal entertainment; (x) a number of alternatives for the reporting of
irregular activity.

In December 2004, additional amendments to the Code of Ethics were adopted.
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 the following:  (i) implementation of minimum
monetary sanctions for violations of the Code; (ii) expansion of the
definition of "access person" under the Code include all Putnam employees
with access to non-public information regarding Putnam-managed mutual fund
portfolio holdings; (iii) lengthening the period during which access persons
are required to complete quarterly reports; (iv) reducing the maximum number
of trades than can be made by Putnam employees in their personal accounts in
any calendar quarter from 25 trades to 10 trades; and (v) lengthening the
required holding period for securities by access persons from 60 days to 90
days.

In March 2005, additional amendments to the Code of Ethics were adopted,
that went into effect on April 1, 2005.  Insofar as such Code of Ethics
applies to the Fund's principal executive officer, principal financial
officer and principal accounting officer, the amendments (i) prohibit Putnam
employees and their immediate family members from having any direct or
indirect personal financial interest in companies that do business with
Putnam (excluding investment holdings in public companies that are not
material to the employee), unless such interest is disclosed and approved by
the Code of Ethics Officer; (ii) prohibit Putnam employees from using Putnam
assets, letterhead or other resources in making political or campaign
contributions, solicitations or endorsements;(iii) require Putnam employees
to obtain pre-clearance of personal political or campaign contributions or
other gifts to government officials or political candidates in certain
jurisdictions and to officials or candidates with whom Putnam has or is
seeking to establish a business relationship and (iv) require Putnam
employees to obtain pre-approval from Putnam's Director of Government
Relations prior to engaging in lobbying activities.

In July 2005, additional amendments to the Code of Ethics were adopted.
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.

Item 3. Audit Committee Financial Expert:
- -----------------------------------------
The Funds' Audit and Pricing Committee is comprised solely of Trustees
who are "independent" (as such term has been defined by the Securities
and Exchange Commission ("SEC") in regulations implementing Section 407
of the Sarbanes-Oxley Act (the "Regulations")).  The Trustees believe
that each of the members of the Audit and Pricing Committee also possess
a combination of knowledge and experience with respect to financial
accounting matters, as well as other attributes, that qualify them for
service on the Committee.  In addition, the Trustees have determined
that all members of the Funds' Audit and Pricing Committee meet the
financial literacy requirements of the New York Stock Exchange's rules
and that Mr. Patterson, Mr. Stephens and Mr. Worley qualify as "audit
committee financial experts" (as such term has been defined by the
Regulations) based on their review of their pertinent experience and
education. Certain other Trustees, although not on the Audit and Pricing
Committee, would also qualify as "audit committee financial experts."
The SEC has stated that the designation or identification of a person as
an audit committee financial expert pursuant to this Item 3 of Form N-CSR
does not impose on such person any duties, obligations or liability that
are greater than the duties, obligations and liability imposed on such
person as a member of the Audit and Pricing Committee and the Board of
Trustees in the absence of such designation or identification.

Item 4. 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 auditors:

                    Audit       Audit-Related   Tax       All Other
Fiscal year ended   Fees        Fees            Fees      Fees
- -----------------   ----------  -------------   -------   ---------
July 31, 2005       $51,560*    $--             $6,089    $26
July 31, 2004       $47,085*    $--             $5,912    $88

* Includes fees of $ 10 and $ 376   billed by the fund's independent auditor
to the fund for audit procedures necessitated by regulatory and litigation
matters for the fiscal years ended July 31, 2005 and July 31, 2004,
respectively.  These fees were reimbursed to the fund by Putnam.

For the fiscal years ended July 31, 2005 and July 31, 2004, the fund's
independent auditors billed aggregate non-audit fees in the amounts of $
201,444 and $ 139,628, 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 represents fees billed for the fund's last two fiscal years.

Audit-Related Fees represents 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 Fees represent fees billed for services relating to an
analysis of recordkeeping fees and fund expense processing.

Pre-Approval Policies of the Audit and Pricing Committee.  The Audit and
Pricing Committee of the Putnam funds has determined that, as a matter of
policy, all work performed for the funds by the funds' independent auditors
will be pre-approved by the Committee and will generally not be subject to
pre-approval procedures.

Under certain circumstances, the Audit and Pricing Committee believes that
it may be appropriate for Putnam Investment Management, LLC ("Putnam
Management") and certain of its affiliates to engage the services of the
funds' independent auditors, but only after prior approval by the Committee.
 Such requests are required to be submitted in writing to the Committee and
explain, among other things, the nature of the proposed engagement, the
estimated fees, and why this work must be performed by that particular audit
firm.  The Committee will review the proposed engagement at its next
meeting.

Since May 6, 2003, all work performed by the independent auditors for the
funds, Putnam Management and any entity controlling, controlled by or under
common control with Putnam Management that provides ongoing services to the
fund was pre-approved by the Committee or a member of the Committee pursuant
to the pre-approval policies discussed above.  Prior to that date, the
Committee had a general policy to pre-approve the independent auditor's
engagements for non-audit services with the funds, Putnam Management and any
entity controlling, controlled by or under common control with Putnam
Management that provides ongoing services to the fund.

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

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

What makes Putnam different?

[GRAPHIC OMITTED: FOUNDER]

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.

[GRAPHIC OMITTED: SIGNATURE]

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

Message from the Trustees

Dear Fellow Shareholder

During the period ended July 31, 2005, the stock market has continued to
show confidence in the strength of the economy and corporate profits, even
as the Federal Reserve Board's more restrictive monetary policy, along
with high energy prices, has begun to influence the performance of bonds
and the pace of expansion. Abroad, stocks have performed even better than
in the United States, despite weaker economic growth in most developed
markets. However, the recent strength of the U.S. dollar against foreign
currencies partially offset the effects of these gains. And in the last
three weeks, investors have just begun to assess the magnitude of
Hurricane Katrina's impact and how it will affect the U.S. economy. Amid
the uncertainties of this environment, the in-depth, professional research
and active management that mutual funds can provide make them an
intelligent choice for today's investors.

We want you to know that 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 keeping with these goals, we have redesigned and
expanded our shareholder reports to make it easier for you to learn more
about your fund. Furthermore, on page 24 we provide information about the
2005 approval by the Trustees of your fund's management contract with
Putnam.

We would also like to take this opportunity to announce the retirement of
one of your fund's Trustees, Ronald J. Jackson, who has been an
independent Trustee of the Putnam funds since 1996. We thank him for his
service.

In the following pages, members of your fund's management team discuss the
fund's performance, strategies, and their outlook for the months ahead. As
always, we thank you for your support of the Putnam funds.

Respectfully yours,

/S/GEORGE PUTNAM, III

Putnam Tax-Free High Yield Fund: potential for high current income exempt
from federal income taxes

Two of the most significant challenges of fixed-income investing are low
interest rates and taxes on income. Putnam Tax-Free High Yield Fund helps
investors reduce the impact of both by investing in higher-yielding
municipal bonds, which offer the potential for a greater stream of income
along with tax advantages.

Municipal bonds are issued by states and local municipalities to raise
funds for building and maintaining public facilities. The income from a
municipal bond is exempt from federal income taxes, and from state taxes
for residents of the state in which the bond is issued. Municipal bonds
are backed by either the issuing city or town or by revenues collected
from usage fees, and as a result have varying degrees of credit risk (the
risk that the issuer won't be able to repay the bond).

Many high-yield municipal bonds are not rated by independent rating
agencies such as Standard & Poor's and Moody's. This is mainly because
many issuers decide not to pursue a rating that might be below investment
grade. As a result, investment companies must do their own research to
determine whether these bonds are prudent investments.

Evaluating a bond's credit risk is one area in which Putnam has particular
expertise. Putnam's municipal bond research team analyzes each issue in
depth and assigns unrated bonds an agency-equivalent Putnam rating --
instead of rating bonds on a pass/fail basis, which is a common practice
in the industry. Although unrated bonds typically represent only a small
portion of the fund's holdings, this analysis helps the management team in
identifying bonds with attractive risk/return profiles from among this
group.

Once the fund has invested in a bond, the fund's management team continues
to monitor developments that affect the bond market, the specific sector
(for example, hospitals or utilities), and the issuer of the bond.
Typically, higher-risk, lower-rated bonds are reviewed more frequently
because of their greater potential risk.

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 approach to research and active management is to
stay a step ahead of the industry and pinpoint opportunities to adjust the
fund's holdings -- either by acquiring more of a particular bond or selling
it -- for the benefit of the fund and its shareholders.

Capital gains, if any, are taxable for federal and, in most cases, state
purposes. For some investors, investment income may be subject to the
federal alternative minimum tax. Income from federally exempt funds may be
subject to state and local taxes. Mutual funds that invest in bonds are
subject to certain risks, including interest-rate risk, credit risk, and
inflation risk. As interest rates rise, the prices of bonds fall.
Long-term bonds are more exposed to interest-rate risk than short-term
bonds. Unlike bonds, bond funds have ongoing fees and expenses. Tax-free
funds may not be suitable for IRAs and other non-taxable accounts.

Understanding tax-equivalent yield

To understand the value of tax-free income, it's 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. The tax-equivalent yield equals the
municipal bond's yield divided by "one minus the tax rate."

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 2005.

0.05 [DIV]  (1.0 - 0.35) = 0.077 = 7.7%

Putnam Tax-Free High Yield Fund seeks to provide a high level of current
income free from federal income tax by investing in a diversified
portfolio of lower-rated and investment-grade municipal bonds. The fund is
intended and may be appropriate for investors seeking tax-advantaged
income who are willing to accept some credit risk.

Report from the fund managers

The year in review

As they have since the spring of 2003, higher-yielding bonds continued to
outperform lower-yielding, higher-quality bonds during the fiscal year
ended July 31, 2005. In this favorable environment, your fund's results at
net asset value (NAV, or without sales charges) outperformed those of its
benchmark, the Lehman Municipal Bond Index, which is composed of
higher-grade municipal bonds. We attribute this strong relative
performance to our emphasis on sectors that strengthened during the period
and our use of strategies designed to protect principal in a challenging
interest-rate environment. Your fund also slightly outperformed the
average for its Lipper peer group.

Market overview

Signs of accelerating economic growth and rising corporate profits
prompted the Federal Reserve Board (the Fed) to increase the federal funds
rate nine times during the 12 months ended July 31, 2005, in gradual
increments of 0.25%. The Fed uses interest-rate increases in its efforts
to rein in economic growth and limit inflationary pressures. However,
while yields on shorter-term securities rose in response to the Fed's
moves, yields on longer-term bonds trended downward, causing a flattening
of the yield curve as rates on both ends of the spectrum converged.

The same conditions that prompted the Fed to raise short-term interest
rates -- an improving economy and rising corporate earnings -- proved
favorable for lower-rated bonds. With bond yields generally at
historically low levels, and confidence buoyed by the growing economy,
investors sought out these bonds, which typically carry higher yields
because of their greater credit risk. Bonds at the lower end of the credit
spectrum, including Ba- and B-rated bonds, turned in the strongest
performance. Among uninsured bonds, and especially bonds rated Baa and
below, yield spreads tightened, and bond prices rose. Certain sectors were
also stronger than others. Based on continued favorable legal rulings,
yields on tobacco settlement bonds generally declined during the period, and
their prices rose accordingly. After they underperformed earlier in the
year, airline- related industrial development bonds (IDBs) staged a
comeback from distressed levels and outperformed over the trailing
six-month period. Callable bonds (which can be redeemed by their issuers
before maturity) outperformed non-callable bonds, as investors expect
these bonds to be less sensitive to interest-rate increases.

Strategy overview

Your fund's duration strategy remained slightly defensive throughout the
fiscal year. Duration is a measure of a fund's sensitivity to changes in
interest rates.

A short duration may help protect principal when interest rates are
rising, but it can reduce the fund's appreciation potential when rates
fall. Although the Fed has been adjusting the federal funds rate upwards
at a measured pace, rates on long-term bonds continued to trend downward,
and the fund's defensive position limited its participation in the price
rally. If long-term rates continue to decline as short-term rates rise,
long rates could fall below short rates. Should this occur, we believe it
is unlikely to endure, so the fund remains defensively positioned.

Increased demand for higher-yielding bonds enabled us to sell bonds into
strength, where appropriate, and to increase the fund's overall portfolio
quality by adding slightly higher-quality bonds. For example, we have been
reducing the fund's airline-related IDBs because we were concerned about
the financial risks facing this industry. We also took profits in other
positions, spreading out assets among holdings we believe have the best
prospects. A more diversified portfolio is less likely to be strongly
influenced -- positively or negatively -- by price swings affecting
individual securities.

Your fund's holdings

Your fund has a portion of assets in tobacco settlement bonds. Although
this sector has been volatile, results for the fiscal year were favorable.
Payments from these bonds are secured by income from tobacco companies'
settlement obligations to certain states, and have generally offered
higher yields than bonds of comparable quality. In what has amounted to an
ongoing threat to this income stream, the Department of Justice (DOJ)
initiated a lawsuit in 1999 against the major tobacco companies seeking
billions of dollars that the DOJ claimed had been obtained fraudulently
from the sale of cigarettes. This sector benefited from a February 4,
2005, ruling by a panel of the U.S. Circuit Court of Appeals for the
District of Columbia against the federal government. Investors believe
this has significantly mitigated the potential financial impact of the
DOJ's lawsuit on tobacco companies and demand for these bonds has
strengthened. The fund's top-performing issues included Badger Tobacco
Asset Securitization Corporation, Wisconsin; Tobacco Settlement Revenue
Management Authority, South Carolina; Tobacco Settlement Financial
Corporation of New Jersey; and Golden State Tobacco Securitization
Corporation, California. Payments by the latter are backed by guarantees
from the state as well as the tobacco companies' settlement.

The fund also benefited from the performance of high-yielding hospital
bonds. The improving economy has contributed to the financial stability of
many companies, including some well-run hospitals, and investor demand for
these bonds has been high. We have begun to take profits in some issues as
they rose in value because we felt other market areas may now provide
better potential returns.

Comparison of the fund's maturity and duration

[GRAPHIC OMITTED: bar chart COMPARISON OF THE FUND'S MATURITY AND DURATION]

This chart compares changes in the fund's duration (a measure of its
sensitivity to interest-rate changes) and its average effective maturity
(a weighted average of the holdings' maturities).

Duration in years           5.4             5.0              4.0

Footnote reads:
Average effective maturity also takes into account put and call features,
where applicable, and reflects prepayments for mortgage-backed securities.


In an improving economy, some lower-rated issues may achieve a higher
credit rating or they may be pre-refunded. This occurs when an issuer
refinances an older, higher-coupon bond by issuing new bonds at current,
lower interest rates. This money is then invested in a secure investment --
usually U.S. Treasury securities -- that mature at the older bond's first
call date, effectively raising the bonds' perceived rating and frequently
its market value. For example, the fund owns bonds issued for Medical
University of South Carolina, which were pre-refunded in December,
effectively raising the credit rating from Baa2/BBB+ to Aaa. A similar,
more recent example was Arkansas State Hospital Development Authority's
Washington Regional Medical Center, which was pre-refunded in July. Both
positions appreciated following the pre-refundings.

Credit quality overview

[GRAPHIC OMITTED: pie chart CREDIT QUALITY OVERVIEW]

Credit qualities shown as a percentage of portfolio value as of July 31,
2005. A bond rated Baa or higher is considered investment grade. The chart
reflects Moody's ratings; percentages may include bonds not rated by
Moody's but considered by Putnam Management to be of comparable quality.
Ratings will vary over time.

A (16.0%)

Aaa (16.0%)

Although the fund has less exposure to airline-related IDBs than most
funds in its peer group, those it did hold contributed positively to
results. The high yields on these bonds continue to attract investors.
However, we do not believe the risks justify the returns available, so we
have limited the fund's holdings to debt backed by what we consider to be
stronger carriers.

Please note that all holdings discussed in this report are subject to
review in accordance with the fund's investment strategy and may vary in
the future.

- ------------------------------------------------------------------------------
The outlook for your fund

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

Based on sustained economic growth, we expect the Fed to continue to raise
interest rates through 2005, a policy that will likely lead to rising bond
yields. Therefore, we plan to maintain the fund's defensive duration
position and to continue to increase its exposure to callable bonds,
which, in our opinion, are likely to outperform in a rising-rate cycle.

We have a positive view of the single-family housing sector and plan to
add selectively to the fund's positions. We believe that the recent
strength of lower-rated, higher-yielding bonds will likely slow and we
plan to modestly upgrade the fund's overall credit exposure. Despite the
sector's recent strength, we remain bearish on airline-related IDBs in
light of likely continued fundamental weaknesses in this sector. Our view
on tobacco settlement bonds is positive and we are seeking to increase the
fund's exposure as opportunities arise.

The views expressed in this report are exclusively those of Putnam
Management. They are not meant as investment advice. Lower-rated bonds may
offer higher yields in return for more risk. Capital gains, if any, are
taxable for federal and, in most cases, state purposes. For some
investors, investment income may be subject to the federal alternative
minimum tax. Income from federally exempt funds may be subject to state
and local taxes. Mutual funds that invest in bonds are subject to certain
risks, including interest-rate risk, credit risk, and inflation risk. As
interest rates rise, the prices of bonds fall. Long-term bonds are more
exposed to interest-rate risk than short-term bonds. Unlike bonds, bond
funds have ongoing fees and expenses. Tax-free funds may not be suitable
for IRAs and other non-taxable accounts.

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 4.50% and 3.25%, respectively (which for class A
shares does not reflect a reduction in sales charges that went into effect
on April 1, 2005; if this reduction had been in place for all periods
indicated, returns would have been higher). 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 A, C, and M shares before
their inception is derived from the historical performance of class B
shares, adjusted for the applicable sales charge (or CDSC) and higher or
lower operating expenses for such shares.

For a portion of the period, this fund limited expenses, without which
returns would have been lower.

A 2% short-term trading fee may be applied to shares exchanged or sold
within 5 days of purchase.

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. In the most
recent six-month period, your fund limited these expenses; had it not done
so, expenses would have been higher. Using the information below, you can
estimate how these expenses affect your investment and compare them with
the expenses of other funds. You may also pay one-time transaction
expenses, including sales charges (loads) and redemption fees, which are
not shown in this section and would have resulted in higher total
expenses. For more information, see your fund's prospectus or talk to your
financial advisor.

- ------------------------------------------------------------------------------
Review your fund's expenses

The table below shows the expenses you would have paid on a $1,000
investment in Putnam Tax-Free High Yield Fund from February 1, 2005, to
July 31, 2005. It also shows how much a $1,000 investment would be worth
at the close of the period, assuming actual returns and expenses.

* 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 7/31/05.
  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

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.

* 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 7/31/05.
  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.

- ------------------------------------------------------------------------------
Compare expenses using industry averages

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.

- ------------------------------------------------------------------------------

 + 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 6/30/05. 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 data for the fund is calculated based on the fund's fiscal-year
period, which ends on July 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 2005 is based on information available as of 6/30/05.

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.

Fund's Overall
Morningstar Risk       0.11

Municipal bond
fund average           0.20

0%   INCREASING RISK   100%

Your fund's Overall Morningstar Risk is shown alongside that of the
average fund in its broad asset class, as determined by Morningstar. The
risk bar broadens the comparison by translating the fund's Overall
Morningstar Risk into a percentile, which is based on the fund's ranking
among all funds rated by Morningstar as of June 30, 2005. A higher Overall
Morningstar Risk generally indicates that a fund's monthly returns have
varied more widely.

Morningstar determines a fund's Overall Morningstar Risk by assessing
variations in the fund's monthly returns -- with an emphasis on downside
variations -- over 3-, 5-, and 10-year periods, if available. Those
measures are weighted and averaged to produce the fund's Overall
Morningstar Risk. The information shown is provided for the fund's class A
shares only; information for other classes may vary. Overall Morningstar
Risk is based on historical data and does not indicate future results.
Morningstar does not purport to measure the risk associated with a current
investment in a fund, either on an absolute basis or on a relative basis.
Low Overall Morningstar Risk does not mean that you cannot lose money on
an investment in a fund. Copyright 2004 Morningstar, Inc. All Rights

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 4.50% maximum sales charge for class A
shares (since reduced to 3.75%) and 3.25% for class M shares.

Contingent deferred sales charge (CDSC) is a charge applied at the time of
the redemption of class B or C shares and assumes redemption at the end of
the period. Your fund's class B CDSC declines from a 5% maximum during the
first year to 1% during the sixth year. After the sixth year, the CDSC no
longer applies. The CDSC for class C shares is 1% for one year after
purchase.

- ------------------------------------------------------------------------------
Share classes

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

Class B shares may be subject to a sales charge upon redemption.

Class C shares are not subject to an initial sales charge and are subject
to a contingent deferred sales charge only if the shares are redeemed
during the first year.

Class M shares have a lower initial sales charge and a higher 12b-1 fee
than class A shares and no sales charge on redemption (except on certain
redemptions of shares bought without an initial sales charge).

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.

- ------------------------------------------------------------------------------
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 advisers. 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 currently
  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 69th percentile in management fees and in the 50th 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). (These expense comparisons do not reflect
  a reduction in your fund's management fee schedule that took effect in
  March 2005. In addition, 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, has 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 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 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 performance at net asset value was in the following percentiles of
its Lipper Inc. peer group (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               62nd              54th

(Because of the passage of time, these performance results may differ from
the performance results for more recent periods shown elsewhere in this
report.)

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 adviser 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 adviser. 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 net assets allocated to
remarketed preferred shares.)

Statement of operations shows the fund's net investment gain or loss. This
is done by first adding up all the fund's earnings -- from dividends and
interest income -- and subtracting its operating expenses to determine net
investment income (or loss). Then, any net gain or loss the fund realized
on the sales of its holdings -- as well as any unrealized gains or losses
over the period -- is added to or subtracted from the net investment result
to determine the fund's net gain or loss for the fiscal year.

Statement of changes in net assets shows how the fund's net assets were
affected by the fund's net investment gain or loss, by distributions to
shareholders, and by changes in the number of the fund's shares. It lists
distributions and their sources (net investment income or realized capital
gains) over the current reporting period and the most recent fiscal
year-end. The distributions listed here may not match the sources listed
in the Statement of operations because the distributions are determined on
a tax basis and may be paid in a different period from the one in which
they were earned.

Financial highlights provide an overview of the fund's investment results,
per-share distributions, expense ratios, net investment income ratios,
and portfolio turnover in one summary table, reflecting the five most
recent reporting periods. In a semiannual report, the highlight table also
includes the current reporting period. For open-end funds, a separate
table is provided for each share class.

Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of
Putnam Tax-Free High Yield 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 Tax-Free High
Yield Fund (the "fund") at July 31, 2005, 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 July 31,
2005, by correspondence with the custodian and brokers, provide a
reasonable basis for our opinion.

Notes to financial statements 7/31/05

Note 1: Significant accounting policies

Putnam Tax-Free High Yield Fund (the "fund") is a series of Putnam Tax
Free Income Trust (the "trust"), a Massachusetts business trust, which is
registered under the Investment Company Act of 1940, as amended, as a
diversified, open end management investment company. The fund pursues its
objective of seeking high current income exempt from federal income tax by
investing primarily in high-yielding, lower rated tax-exempt securities
constituting a portfolio that Putnam Investment Management, LLC ("Putnam
Management"), the fund's manager, an indirect wholly-owned subsidiary of
Putnam, LLC, believes does not involve undue risk to income or principal.
The fund invests in higher yielding, lower rated bonds that have a higher
rate of default due to the nature of the investments.

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 do not pay contingent deferred sales charges.
Prior to April 1, 2005, the maximum front-end sales charge for class A
shares was 4.50%. 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 are subject to the
same fees as class B shares, except that 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 each class' distribution fee, 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 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.

Investments for which market quotations are readily available are valued
at the last reported sales price on their principal exchange, or official
closing price for certain markets. If no sales are reported -- as in the
case of some securities traded over-the-counter -- a security is valued at
its last reported bid price. Many securities markets and exchanges outside
the U.S. close prior to the close of the New York Stock Exchange and
therefore the closing prices for securities in such markets or on such
exchanges may not fully reflect events that occur after such close but
before the close of the New York Stock Exchange. Accordingly, on certain
days, the fund will fair value foreign securities taking into account
multiple factors, including movements in the U.S. securities markets. The
number of days on which fair value prices will be used will depend on
market activity and it is possible that fair value prices will be used by
the fund to a significant extent.

B) Security transactions and related investment income Security
transactions are recorded on the trade date (date the order to buy or sell
is executed). Gains or losses on securities sold are determined on the
identified cost basis.

Interest income is recorded on the accrual basis. Non-cash dividends, if
any, are recorded at the fair market value of the securities received. 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 forward commitment basis may be settled
a month or more after the trade date; interest income is accrued based on
the terms of the securities. Losses may arise due to changes in the market
value of the underlying securities or if the counterparty does not perform
under the contract.

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

The potential risk to the fund is that the change in value of futures and
options contracts may not correspond to the change in value of the hedged
instruments. In addition, losses may arise from changes in the value of
the underlying instruments, if there is an illiquid secondary market for
the contracts, or if the counterparty to the contract is unable to
perform. 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 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.

At July 31, 2005, the fund had a capital loss carryover of $218,734,176
available to the extent allowed by the Code to offset future net capital
gain, if any. This amount includes $43,937,109 of capital losses acquired
in connection with the acquisition of Putnam Municipal Income Fund which
are subject to limitations imposed by the Internal Revenue Code. The
amount of the carryover and the expiration dates are:

Loss Carryover               Expiration

   $23,145,357            July 31, 2006
    34,691,361            July 31, 2007
     8,579,409            July 31, 2008
     1,682,906            July 31, 2009
     1,466,587            July 31, 2010
    24,697,987            July 31, 2011
    87,799,907            July 31, 2012
    36,670,662            July 31, 2013

Pursuant to federal income tax regulations applicable to regulated
investment companies, the fund has elected to defer to its fiscal year
ending July 31, 2006 $2,773,207 of losses recognized during the period
November 1, 2004 to July 31, 2005 a portion of which could be limited by
Section 381 of the Code.

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 least annually. The
amount and character of income and gains to be distributed are determined
in accordance with income tax regulations which may differ from generally
accepted accounting principles. These differences include temporary and
permanent differences of losses on wash sale transactions, post-October
loss deferrals, the expiration of capital loss carryover, dividends
payable, defaulted bond interest, unrealized gains on certain futures
contracts, market discount, straddle loss deferrals, and partnership
income. 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 July
31,2005, the fund reclassified $98,808 to increase undistributed net
investment income and $8,645,185 to decrease paid-in-capital, with an
decrease to accumulated net realized losses of $8,546,377.

G) 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

Putnam Management is paid for management and investment advisory services
monthly 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 asset value
of the fund or (ii) the following annual rates: 0.60% of the first $500
million of average net assets, 0.50% of the next $500 million, 0.45% of
the next $500 million, 0.40% of the $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. Prior to March 18, 2005, such fee was based on the
following annual rates: 0.65% of the first $500 million of average net
assets, 0.55% of the next $500 million, 0.50% of the next $500 million,
0.45% of the next $5 billion, 0.425% of the next $5 billion, 0.405% of the
next $5 billion, and 0.39% of the next $5 billion and 0.38% thereafter.

Putnam Management has agreed to waive fees and reimburse expenses of the
fund through July 31, 2006 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 July 31,
2005, Putnam Management waived $266,693 of its management fee from the
fund.

For the period ended July 31, 2005, Putnam Management has assumed $22,457
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 6).

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 July 31, 2005,
the fund paid PFTC $913,458 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 July 31, 2005, the
fund's expenses were reduced by $98,522 under these arrangements.

Each independent Trustee of the fund receives an annual Trustee fee, of
which $494, 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. 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 noncontributory defined benefit pension
plan (the "Pension Plan") covering all Trustees of the fund who have
served as a Trustee for at least five years. Benefits under the Pension
Plan are equal to 50% of the Trustee's average total retainer and meeting
fees for the three years preceding retirement. Pension expense for the
fund is included in Trustee compensation and expenses in the statement of
operations. Accrued pension liability is included in Payable for Trustee
compensation and expenses in the statement of assets and liabilities. The
Trustees have terminated the Pension Plan with respect to any Trustee
first elected after 2003.

The fund has adopted distribution plans (the "Plans") with respect to its
class A, class B, class C 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 March 21, 2005 and (ii) 0.25% on all other
net assets of the fund attributable to class A shares.

For the year ended July 31, 2005, Putnam Retail Management, acting as
underwriter, received net commissions of $21,321 and $336 on the sale of
class A and class M shares, respectively, and received $191,406 and $671
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 July 31,
2005, Putnam Retail Management, acting as underwriter, received $165 on
class A redemptions.

Note 3: Purchases and sales of securities

During the year ended July 31, 2005, cost of purchases and proceeds from
sales of investment securities other than short-term investments
aggregated $249,587,975 and $311,269,687, respectively. There were no
purchases or sales of U.S. government securities.

Note 6: 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 shareholders and the funds. The restitution amount will be
allocated to shareholders pursuant to a plan developed by an independent
consultant, with payments to shareholders 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 Investments has recorded a charge of $30 million for the estimated
cost, excluding interest, that it believes will be necessary to address
issues relating to the calculation of certain amounts paid by the Putnam
mutual funds in previous years. The previous payments were cost
reimbursements by the Putnam funds to Putnam for transfer agent services
relating to defined contribution operations. Putnam currently anticipates
that any payments made by Putnam related to this issue will be paid to the
Putnam funds. Review of this issue is ongoing.

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.

Note 7: Acquisition of Putnam Municipal Income Fund

On March 21, 2005, the fund issued 47,117,436; 7,626,046; 953,897; and
535,178 class A, class B, class C and class M shares, respectively, in
exchange for 69,692,992; 11,303,507; 1,410,792; and 791,929 class A, class
B, class C and class M shares of Putnam Municipal Income Fund to acquire
that fund's net assets in a tax-free exchange approved by the
shareholders. The net assets of the fund and Putnam Municipal Income Fund
on March 18, 2005, valuation date, were $965,410,122 and $722,220,765
respectively. On March 18, 2005, Putnam Municipal Income Fund had
distributions in excess of net investment income of $114,175, accumulated
net realized loss of $57,858,443 and unrealized appreciation of
$28,646,579. The aggregate net assets of the fund immediately following
the acquisition were $1,687,630,887.

Information presented in the Statement of operations and changes in net
assets reflect only operations of Putnam Tax-Free High Yield Fund.

Item 2. Code of Ethics:
- -----------------------
(a) All officers of the Fund, including its principal executive, financial and
accounting officers, are employees of Putnam Investment Management, LLC,
the Fund's investment manager.  As such they are subject to a comprehensive
Code of Ethics adopted and administered by Putnam Investments which is
designed to protect the interests of the firm and its clients.  The Fund
has adopted a Code of Ethics which incorporates the Code of Ethics of
Putnam Investments with respect to all of its officers and Trustees who are
employees of Putnam Investment Management, LLC.  For this reason, the Fund
has not adopted a separate code of ethics governing its principal
executive, financial and accounting officers.

(c) In July 2004, 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.  Some of these
amendments were adopted as a result of Putnam Investment Management's
partial settlement order with the SEC on November 13, 2003.  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 the following:  (i) a 90-day blackout period for all shares of Putnam
open-end funds (except for money market funds) purchased or sold (including
exchanges into or out of a fund) by Putnam employees and certain family
members; (ii) a one-year holding period for all access persons that operates
in the same manner as the 90-day rule; (iii) delivery by Putnam employees to
the Code of Ethics Administrator of both quarterly account statements for
all brokerage accounts (irrespective of activity in the accounts) and
account statements for any Putnam funds not held at Putnam or for any funds
sub-advised by Putnam; (iv) a prohibition of Putnam employees from making
more than 25 trades in individual securities in their personal accounts in
any given quarter; (v) the extension of the existing prohibition of access
persons from a purchase and sale or sale and purchase of an individual
security within 60 days to include trading based on tax-lot election; (vi)
the inclusion of trades in Marsh & McLennan Companies, Inc. (ultimate parent
company of Putnam Investment Management) securities in pre-clearance and
reporting requirements; (vii) a prohibition of limit and good-until-canceled
orders as inconsistent with the requirements of daily pre-clearance; (viii)
new limits and procedures for accounts managed by outside managers and
brokers, in order for trading in such accounts to be exempt from
pre-clearance requirements; (ix) a new gift and entertainment policy that
imposes a reporting obligation on all meals and entertainment and new limits
on non-meal entertainment; (x) a number of alternatives for the reporting of
irregular activity.

In December 2004, additional amendments to the Code of Ethics were adopted.
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 the following:  (i) implementation of minimum
monetary sanctions for violations of the Code; (ii) expansion of the
definition of "access person" under the Code include all Putnam employees
with access to non-public information regarding Putnam-managed mutual fund
portfolio holdings; (iii) lengthening the period during which access persons
are required to complete quarterly reports; (iv) reducing the maximum number
of trades than can be made by Putnam employees in their personal accounts in
any calendar quarter from 25 trades to 10 trades; and (v) lengthening the
required holding period for securities by access persons from 60 days to 90
days.

In March 2005, additional amendments to the Code of Ethics were adopted,
that went into effect on April 1, 2005.  Insofar as such Code of Ethics
applies to the Fund's principal executive officer, principal financial
officer and principal accounting officer, the amendments (i) prohibit Putnam
employees and their immediate family members from having any direct or
indirect personal financial interest in companies that do business with
Putnam (excluding investment holdings in public companies that are not
material to the employee), unless such interest is disclosed and approved by
the Code of Ethics Officer; (ii) prohibit Putnam employees from using Putnam
assets, letterhead or other resources in making political or campaign
contributions, solicitations or endorsements;(iii) require Putnam employees
to obtain pre-clearance of personal political or campaign contributions or
other gifts to government officials or political candidates in certain
jurisdictions and to officials or candidates with whom Putnam has or is
seeking to establish a business relationship and (iv) require Putnam
employees to obtain pre-approval from Putnam's Director of Government
Relations prior to engaging in lobbying activities.

In July 2005, additional amendments to the Code of Ethics were adopted.
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.

Item 3. Audit Committee Financial Expert:
- -----------------------------------------
The Funds' Audit and Pricing Committee is comprised solely of Trustees
who are "independent" (as such term has been defined by the Securities
and Exchange Commission ("SEC") in regulations implementing Section 407
of the Sarbanes-Oxley Act (the "Regulations")).  The Trustees believe
that each of the members of the Audit and Pricing Committee also possess
a combination of knowledge and experience with respect to financial
accounting matters, as well as other attributes, that qualify them for
service on the Committee.  In addition, the Trustees have determined
that all members of the Funds' Audit and Pricing Committee meet the
financial literacy requirements of the New York Stock Exchange's rules
and that Mr. Patterson, Mr. Stephens and Mr. Worley qualify as "audit
committee financial experts" (as such term has been defined by the
Regulations) based on their review of their pertinent experience and
education. Certain other Trustees, although not on the Audit and Pricing
Committee, would also qualify as "audit committee financial experts."
The SEC has stated that the designation or identification of a person as
an audit committee financial expert pursuant to this Item 3 of Form N-CSR
does not impose on such person any duties, obligations or liability that
are greater than the duties, obligations and liability imposed on such
person as a member of the Audit and Pricing Committee and the Board of
Trustees in the absence of such designation or identification.

Item 4. 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
auditors:

                    Audit       Audit-Related   Tax       All Other
Fiscal year ended   Fees        Fees            Fees      Fees
- -----------------   ----------  -------------   -------   ---------
July 31, 2005       $64,546*    $5,500**        $7,040    $906
July 31, 2004       $69,779*    $--             $6,306    $206

* Includes fees of $ 25 and $ 888  billed by the fund's independent
auditor to the fund for audit procedures necessitated by regulatory and
litigation matters for the fiscal years ended July 31, 2005 and July 31,
2004, respectively.  These fees were reimbursed to the fund by Putnam.

** Includes fees billed to the fund for services relating to one or more
fund mergers.  A portion of such fees was paid by Putnam Management.

For the fiscal years ended July 31, 2005 and July 31, 2004, the fund's
independent auditors billed aggregate non-audit fees in the amounts of $
208,775 and $ 140,140 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 represents fees billed for the fund's last two fiscal years.

Audit-Related Fees represents 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 Fees represent fees billed for services relating to an
analysis of recordkeeping fees and fund expense processing.

Pre-Approval Policies of the Audit and Pricing Committee.  The Audit and
Pricing Committee of the Putnam funds has determined that, as a matter
of policy, all work performed for the funds by the funds' independent
auditors will be pre-approved by the Committee and will generally not be
subject to pre-approval procedures.

Under certain circumstances, the Audit and Pricing Committee believes
that it may be appropriate for Putnam Investment Management, LLC
("Putnam Management") and certain of its affiliates to engage the
services of the funds' independent auditors, but only after prior
approval by the Committee.  Such requests are required to be submitted
in writing to the Committee and explain, among other things, the nature
of the proposed engagement, the estimated fees, and why this work must
be performed by that particular audit firm.  The Committee will review
the proposed engagement at its next meeting.

Since May 6, 2003, all work performed by the independent auditors for
the funds, Putnam Management and any entity controlling, controlled by
or under common control with Putnam Management that provides ongoing
services to the fund was pre-approved by the Committee or a member of
the Committee pursuant to the pre-approval policies discussed above.
Prior to that date, the Committee had a general policy to pre-approve
the independent auditor's engagements for non-audit services with the
funds, Putnam Management and any entity controlling, controlled by or
under common control with Putnam Management that provides ongoing
services to the fund.

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