Dear Shareholder:

It is a pleasure to greet you in our new roles as Chairman of the
Trustees and President of the Funds. As you know, both of us have been
members of the Board of Trustees for a number of years -- years during
which the global securities markets, the mutual fund industry, and
Putnam itself have experienced tremendous growth and change.

As we look to the future, we are certain that the changes will be
breathtaking in their scope. What will not change is the Trustees'

dedication to serving the best interests of our shareholders.

We welcome the challenges that lie ahead and are confident that Putnam
and your Board will continue to face those challenges successfully as
they have for more than 60 years. We look forward to helping you meet
your financial objectives for many years to come.

Respectfully yours,

/S/ JOHN A. HILL                   /S/GEORGE PUTNAM, III

REPORT FROM FUND MANAGEMENT

Richard P. Wyke

The tide is finally starting to turn in the financial markets. Many
equity markets have struggled and declined so far this year, but the
bond market, as measured by the 30-year Treasury bond, recorded a 6.30%
total return for the period ended July 31, 2000. It is true that the
first half of this fiscal year was a difficult one for bonds and bond
investors, but the positive performance of the  second half of the year
set the stage for improving performance from Putnam Tax-Free Insured
Fund.

* YEAR FULL OF CHANGE

Fiscal 2000 was a year full of uncertainty. The 10-year economic
expansion in the United States surpassed everyone's expectations and
provoked renewed worry over inflation. After six interest-rate increases
by the Federal Reserve Board during the period, it was clear that the
fight against inflation would be a tough one.

During the year, the Treasury announced its debt buy-back  program. The
move threw the Treasury market off balance by greatly diminishing
supply. Finally, with sufficient signs of a slowdown in the economy in
late spring and a consensus that the Fed was satisfied with the slower
pace of the economy, we have begun to experience a more comfortable
environment in the municipal bond market.

* WIDENING OF CREDIT SPREADS AFFECTS MARKET FOR INSURED BONDS

Another major event that began in the third quarter of calendar 1999 and
extended into this year was the widening of credit spreads in the
municipal bond market -- a situation in which the difference between
interest rates on lower-rated investment-grade bonds and higher-rated
bonds was growing. Lower-tier investment-grade bonds carried interest
rates that were three quarters of a percentage point above those of
Aaa/AAA-rated bonds. Numerous defaults from several troubled bond
issuers and the resulting price declines caused the wider spreads and
made potential buyers more reluctant to consider investing in this
sector.


"The bond market, by virtue of its positive performance in recent
months, seems to be comfortable with the  economy's pace and direction."

-- Richard P. Wyke, portfolio manager


The widening of credit spreads and lack of investor interest in the
lower-rated investment-grade market affected the market for insured
municipal bonds, greatly boosting demand. The guarantee of timely
principal and interest payments that comes with insured municipal bonds
suddenly became appealing to investors who were concerned about the
increase in defaults and the stock market's volatility.

* FUND USES SEVERAL STRATEGIES TO CAPTURE HIGHER INCOME

A discussion of our duration strategy is always pertinent to the fund's
performance. Duration is a measure of the portfolio's  sensitivity to
interest-rate changes. During the period, our strategy was to keep the
fund's duration at about 8 1/2 years, slightly shorter than that of its
benchmark. There was one exception to this strategy; in March, we
briefly lengthened duration during a bond market rally. This one-month
period of locking in longer maturities significantly helped the fund's
performance because we purchased bonds with higher interest rates that
have recently appreciated in value.

Sometimes we can boost performance by underweighting a certain type of
bond. This was the case recently with deeply discounted bonds, those
with a market value far below their $1,000 face amount. As interest
rates have risen, these bonds have severely underperformed. Deeply
discounted bonds usually mean a large capital gains tax and potentially
taxable regular income for investors and so demand for them is small.
Low demand drives their prices even lower than those of other discount
bonds in a rising-rate environment. Fortunately the fund did not own a
significant percentage of deeply discounted bonds, and thus this
strategy of omission helped the fund's performance.

* NEW YORK HEALTH-CARE BONDS OFFERED UNIQUE OPPORTUNITY

In previous reports, we have mentioned our strategy of taking profits
from some of our California holdings and investing the proceeds into
other states offering what we considered greater opportunity. In our
opinion, several California bonds had reached their peak in terms of
performance. We believed that New York, a state with high taxes and
strong investor demand for tax-exempt investments, had more attractive
potential.

In September, Nassau County, one of the wealthier counties in the state,
was preparing to issue $260 million in revenue bonds to acquire and make
capital improvements to the Nassau County Medical Center. While planning
was underway for this bond issue, it became public knowledge that the
county was having  difficulty balancing its budget. As a result, the
credit rating agencies downgraded the county's debt. When the Nassau
County Health Care System bonds came to market, they traded lower
because of the negative publicity, even though they were insured. Given
this situation, we were able to purchase Nassau County Health Care
System revenue bonds yielding 5.33% and 5.60%. Later in the year, we
also purchased Nassau County general obligation bonds at especially
attractive prices.

* BONDS MOVING INTO LIMELIGHT

The big question for the future is whether the economy will slow down to
a pace that is acceptable to the Fed and its battle against inflation.
Consumers in the United States are still buying goods and services at a
record rate, pushing up retail sales in July and causing some
uncertainty about inflation. However, many analysts are convinced that
the Fed will not raise interest rates again because several other
indicators, such as slower job growth, a drop in the rate of housing
construction, and strong productivity, suggest that the economy has
cooled.

The bond market, by virtue of its positive performance in recent months,
seems comfortable with the economy's pace and direction. Bond investors
have waited a long time for a shift in sentiment and if the equity
markets remain unsteady and economic growth without inflation becomes an
accepted reality, municipal bondholders should benefit from the
subsequent decline in interest rates.

The views expressed here are exclusively those of Putnam Management.
They are not meant as investment advice. Although the described holdings
were viewed favorably as of 7/31/00, there is no guarantee the fund will
continue to hold these securities in the future. Shares of the fund are
not insured and their price will fluctuate with market conditions.

Past performance is not indicative of future results. More recent
returns may be worth more or less than those shown. Returns for class A
and class M shares reflect the current maximum initial sales charges of
4.75% and 3.25%, respectively. Class B share returns for the 1-, 5-,
10-year, and life of fund periods reflect the applicable contingent
deferred sales charge (CDSC), which is 5% in the first year, declines to
1% in the sixth year, and is eliminated thereafter. Returns shown for
class A and class M shares for periods prior to their inception are
derived from the historical performance of class B shares, adjusted in
the case of public offering price to reflect the initial sales charge
currently applicable to each class, but have not been adjusted to
reflect differences in expenses, which are lower for class A and M
shares than for class B shares. For class C shares, returns for periods
prior to their inception are derived from the historical performance of
class B shares, adjusted to reflect both the CDSC currently applicable
to class C shares, which is 1% for the first year and is eliminated
thereafter, and the higher operating expenses applicable to class C
shares. All returns assume reinvestment of distributions at NAV.
Investment return and principal value will fluctuate so that an
investor's shares when redeemed may be worth more or less than their
original cost.

Past performance is no assurance of future results. More recent returns
may be more or less than those shown. They do not take into account any

TERMS AND DEFINITIONS

Total return shows how the value of the fund's shares changed over time,
assuming you held the shares through the entire period and reinvested
all distributions in the fund.

Class A shares are generally subject to 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.

Net asset value (NAV) is the value of all your fund's assets, minus any
liabilities, divided by the number of outstanding shares, not including
any initial or contingent deferred sales charge.

Public offering price (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance
figures shown here assume the 4.75% maximum sales charge for class A
shares 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.


COMPARATIVE BENCHMARKS

Lehman Brothers Municipal Bond Index is an unmanaged list of long-term
fixed-rate investment-grade tax-exempt bonds representative of the
municipal bond market. The index assumes reinvestment of all
distributions and interest payments and does not take into account
brokerage fees or taxes. Securities in the fund do not match those in
the index and performance of the fund will differ. It is not possible to
invest directly in an index.

Consumer price index (CPI) is a commonly used measure of  inflation; it
does not represent an investment return.


A GUIDE TO THE FINANCIAL STATEMENTS

These sections of the report, preceded by the Report of independent
accountants, 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
for the reporting period. This is determined by adding up all the fund's
earnings -- from dividends and interest income -- and subtracting its
operating expenses. This statement also lists any net gain or loss the
fund realized on the sales of its holdings and -- for holdings that
remain in the portfolio -- any change in unrealized gains or losses over
the period.

Statement of changes in net assets  shows how the fund's net assets were
affected 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 ACCOUNTANTS
For the fiscal year ended July 31, 2000

To the Trustees of Putnam Tax-Free Income Trust and
Shareholders of Putnam Tax-Free Insured Fund

In our opinion, the accompanying statement of assets and liabilities,
including the fund's portfolio (except for bond ratings), 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 Insured Fund (the "fund") at July
31, 2000, and the results of its operations, the changes in its net
assets and the financial highlights for the periods indicated, in
conformity with accounting principles generally accepted in the United
States. 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 auditing standards
generally accepted in the United States, which 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,
2000 by correspondence with the custodian, provide a reasonable basis
for the opinion expressed above.

  (a) Percentages indicated are based on net assets of $502,959,444.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to
      be the most recent ratings available at July 31, 2000 for the securities
      listed. Ratings are generally ascribed to securities at the time of
      issuance. While the agencies may from time to time revise such ratings,
      they undertake no obligation to do so, and the ratings do not
      necessarily represent what the agencies would ascribe to these
      securities at July 31, 2000. Securities rated by Putnam are indicated by
      "/P" and are not publicly rated. Ratings are not covered by the Report
      of independent accountants.

  (b) The aggregate identified cost on a tax basis is $483,493,718,
      resulting in gross unrealized appreciation and depreciation of
      $22,598,992 and $7,785,190, respectively, or net unrealized appreciation
      of $14,813,802.

(STP) The interest rate and date shown parenthetically represent the new
      interest rate to be paid and the date the fund will begin receiving
      interest income at this rate.

(RES) Restricted, excluding 144A securities, as to public resale. The
      total market value of restricted securities held at July 31, 2000 was
      $17,842,000 or 3.5% of net assets.

(SEG) A portion of this security was pledged and segregated with the
      custodian to cover margin requirements for futures contracts at July 31,
      2000.

      The rates shown on IFB and IF COP, which are securities paying
      interest rates that vary inversely to changes in the market interest
      rates, FRB's and VRDN's are the current interest rates at July 31, 2000.

      The fund had the following industry group concentrations greater

NOTES TO FINANCIAL STATEMENTS
July 31, 2000

Note 1
Significant accounting policies

Putnam Tax-Free Insured Fund (the "fund") is a series of Putnam Tax-Free
Income Trust (the "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
shares are sold with a maximum front-end sales charge of 4.75%. Class B
shares, which convert to class A shares after approximately eight years,
do not pay a front-end sales charge but pay a higher ongoing
distribution fee than class A shares, and are subject to a contingent
deferred sales charge, if those shares are redeemed within six years of
purchase. Class C shares have a higher ongoing distribution fee than
class B shares and have a one-year 1.00% contingent deferred sales
charge and do not convert to Class A shares. Class M shares are sold
with a maximum front end sales charge of 3.25% and pay an ongoing
distribution fee that is higher than class A shares but lower than class
B and class C shares.

Expenses of the fund are borne pro-rata by the holders of each class of
shares, except that each class bears expenses unique to that class
(including the distribution fees applicable to such class). Each class
votes as a class only with respect to its own distribution plan or other
matters on which a class vote is required by law or determined by the
Trustees. Shares of each class would receive their pro-rata share of the
net assets of the fund, if the fund were liquidated. In addition, the
Trustees declare separate dividends on each class of shares.

The following is a summary of significant accounting policies
consistently followed by the fund in the preparation of its financial
statements. The preparation of financial statements is in conformity
with generally accepted accounting principles and requires management to
make estimates and assumptions that affect the reported amounts of
assets and liabilities of 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 stated on the basis
of valuations provided by a pricing service, approved by the Trustees,
which uses information with respect to transactions in bonds, quotations
from bond dealers, market transactions in comparable securities and
various relationships between securities in determining value.
Restricted securities are stated 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 accounted for 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.

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. 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.

Futures contracts are valued at the quoted daily settlement prices
established by the exchange on which they trade. 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.

D) Line of credit The fund has entered into a committed line of credit
with certain banks. This line of credit agreement includes restrictions
that the fund maintain an asset coverage ratio of at least 300% and
borrowings must not exceed prospectus limitations. For the year ended
July 31, 2000, the fund had no borrowings against the line of credit.

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 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 Internal Revenue Code of 1986, 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, 2000, the fund had a capital loss carryover of approximately
$4,392,000 available to offset future capital gains, if any. The amount
of the carryover and the expiration dates are:

Loss Carryover    Expiration
--------------    ------------------
    $  468,000    July 31, 2007
     3,924,000    July 31, 2008

F) Distributions to shareholders Income dividends are recorded daily by
the fund and are paid monthly. Capital gain distributions, 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, dividends payable, 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,
2000, the fund reclassified $170,133 to decrease distributions in excess
of net investment income and $166,951 to decrease paid-in-capital, with
an increase to accumulated net realized losses of $3,182. The
calculation of net investment income per share in the financial
highlights table excludes these adjustments.

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.

H) Amortization of bond premium and accretion of bond discount Any
premium resulting from the purchase of securities in excess of maturity
value is amortized on a yield-to-maturity basis. The premium in excess
of the call price, if any, is amortized to the call date; thereafter,
the remaining excess premium is amortized to maturity. Discounts on zero
coupon bonds, original issue discount, and stepped-coupon bonds are
accreted according to the yield-to-maturity basis.

Note 2
Management fee, administrative
services and other transactions

Compensation of Putnam Investment Management, Inc., ("Putnam
Management") the fund's manager, a wholly owned subsidiary of Putnam
Investments, Inc., for management and investment advisory services is
paid quarterly based on the average net assets of the fund. Such fee is
based upon 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 and 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.

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 Investments, Inc.
Investor servicing agent functions are provided by Putnam Investor
Services, a division of PFTC.

For the year ended July 31, 2000, fund expenses were reduced by $205,225
under expense offset arrangements with PFTC and brokerage service
arrangements. Investor servicing and custodian fees reported in the
Statement of operations exclude these credits. The fund could have
invested a portion of the assets utilized in connection with the expense
offset arrangements in an income producing asset if it had not entered
into such arrangements.

Each Trustee of the fund receives an annual Trustee fee, of which $768
has been allocated to the fund, and an additional fee for each Trustees
meeting attended. Trustees receive additional fees for attendance at
certain committee meetings.

The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan")
which allows the Trustees to defer the receipt of all or a portion of
Trustees Fees payable on or after July 1, 1995. The deferred fees remain
invested in certain Putnam funds until distribution in accordance with
the Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension
plan (the "Pension Plan") covering all Trustees of the fund who have
served as a Trustee for at least five years. Benefits under the Pension
Plan are equal to 50% of the Trustee's average total retainer and
meeting fees for the three years preceding retirement. Pension expense
for the fund is included in Compensation of Trustees in the Statement of
operations. Accrued pension liability is included in Payable for
compensation of Trustees in the Statement of assets and liabilities.

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, Inc., a wholly-owned subsidiary of
Putnam Investments Inc., for services provided and expenses incurred by
it in distributing shares of the fund. The Plans provide for payments by
the fund to Putnam Retail Management, Inc. at an annual rate 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 an annual rate of 0.20%, 0.60%,
1.00% and 0.50% of the average net assets attributable to class A, class
B, class C and class M shares, respectively.

For the year ended July 31, 2000, Putnam Retail Management, Inc., acting
as underwriter received net commissions of $22,629 and $437 from the
sale of class A and class M shares, respectively, and received $574,692
and $2,646 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, 2000, Putnam Retail
Management, Inc., acting as underwriter received $4,973 on class A
redemptions.

Note 3
Purchases and sales of securities

During the year ended July 31, 2000, cost of purchases and proceeds from
sales of investment securities other than short-term investments
aggregated $115,655,761 and $194,157,377, respectively. There were no
purchases or sales of U.S. government obligations.

Note 4

Dear Shareholder:

It is a pleasure to greet you in our new roles as Chairman of the
Trustees and President of the Funds.  As you know, both of us have been
members of the Board of Trustees for a number of years -- years during
which the global securities markets, the mutual fund industry, and
Putnam itself have experienced tremendous growth and change.

As we look to the future, we are certain that the changes will be
breathtaking in their scope. What will not change is the Trustees'
dedication to serving the best interests of our shareholders.

We welcome the challenges that lie ahead and are confident that Putnam
and your Board will continue to face those challenges successfully as
they have for more than 60 years.  We look forward to helping you meet
your financial objectives for many years to come.

Respectfully yours,

/S/ JOHN A. HILL                   /S/GEORGE PUTNAM, III

REPORT FROM FUND MANAGEMENT

Blake E. Anderson

Compared with the stock market's swinging pendulum of performance during
the past several months, the municipal bond market has offered
tax-conscious investors relative calm. In fact, since mid May, municipal
bond performance has gradually improved. Unfortunately the Federal
Reserve Board's diligent inflation-fighting interest-rate increases have
limited the appreciation potential for all fixed-income investments.
Nonetheless, Putnam Tax-Free High Yield Fund's 2000 fiscal year has
provided numerous opportunities that we have turned to the fund's
advantage.

Total return for 12 months ended 7/31/00

Past performance is no indication of future results. Performance
information for longer periods and explanation of performance
calculation methods begin on page 6.

* BOND MARKET INCHES UPWARD; MUNI PRICES STAY  RELATIVELY STRONG

As the period began, municipal bonds were laboring under  difficult
market conditions. Later in the year, rising interest rates and a
seasonal surge in demand brought on by January's large number of coupon
payments and bond calls put quite a damper on performance. In April, the
entire fixed-income market enjoyed a brief bump up in price as the stock
market began to sell off and nervous investors flocked to bonds. The
rally was short-lived, however, as inflation concerns and fears of
continued interest-rate increases by the Fed proceeded to push down
prices throughout the fixed-income market. The good news is that
municipal bond prices held up better than Treasuries -- and continue to
offer solid opportunity for investors with tax considerations.

Beginning in June, municipal bond performance began to pick up relative
to U.S. Treasuries, the traditional taxable investment used as a
benchmark for munis. The market began to anticipate the next big
seasonal surge in demand, which typically occurs after the July 1 coupon
payments and bond calls. Consequently municipal bond prices began to
rise again, and your fund's  holdings appreciated.


[GRAPHIC OMITTED: horizontal bar chart TOP INDUSTRY SECTORS]

TOP INDUSTRY SECTORS*

Health care              21.6%

Housing                   9.6%

Utilities                 8.2%

Transportation            6.2%

Waste management          3.5%

Footnote reads:
*Based on net assets as of 7/31/00. Holdings will vary over time.


In fact, the entire fixed-income market began to strengthen in mid May.
Market participants began to anticipate correctly that the Fed would not
raise short-term interest rates again in June, and that the tightening
cycle was nearing its end. Investors began to ease back into the bond
market, believing that the Fed had inflation under control and that the
economy was beginning to slow.

On balance, munis performed well relative to comparable taxable
investments over the period. They did modestly underperform Treasuries,
however, largely because of the unusual technical  factors affecting
Treasury performance rather than difficulties with munis. Federal
government tax surpluses and a program of buying back large numbers of
long-term Treasuries have reduced Treasury supply and created a uniquely
favorable performance situation for these bonds.


[GRAPHIC OMITTED: pie chart CREDIT QUALITY OVERVIEW]

CREDIT QUALITY OVERVIEW*

Aaa/AAA -- 28.0%

Aa/AA -- 5.6%

A -- 7.0%

Baa/BBB -- 15.7%

Ba/BB -- 20.3%

B -- 19.6%

Other -- 3.8%

Footnote reads:
*As a percentage of market value as of 7/31/00. A bond rated BBB/Baa or
 higher is considered investment grade. Percentages may include unrated
 bonds considered by Putnam Management to be of comparable quality.
 Ratings will vary over time.


* WIDENING SPREADS PROVIDE OPPORTUNITY

Over the past year, we have continued to seek opportunities to add
lower-rated higher-yielding securities to the portfolio in order to
bring the fund more in line with its competitive universe. This process
takes time, however, and in the meantime, the portfolio's quality
remains somewhat higher than that of its competitors. As credit spreads
widened between investment-quality bonds and lower-quality bonds over
the period, the fund's higher-quality portfolio helped protect the share
price.

Widening credit spreads also provide us with additional opportunities to
strengthen the fund's income stream. When weakness in the bond market
persisted during the early part of the period, we took advantage of
falling bond prices to purchase some bonds with higher yields and longer
maturities, simultaneously selling bonds in the intermediate range of
maturities. This strategy slightly extended portfolio duration, which
proved beneficial when the outperformance by longer-term Treasuries
helped lift the performance of longer-term bonds, inluding municipals.
During periods of municipal market strength, we selectively sold some
holdings to capture profits for the fund.

Putnam has an experienced team of credit analysts who enable us to
evaluate even those credits that are unrated by major rating agencies.
This allows us to purchase undervalued securities and securities whose
current ratings may not fully reflect their performance potential. In
recent months, yields on BAA-rated bonds have been about 75 to 100 basis
points more than yields on AAA-rated bonds -- an attractive yield
difference that, in our view, compensates investors for the slightly
higher risk inherent in a BBB-rated bond.

"Against a backdrop of  continued economic growth, today's wide spread
between yields on lower quality, high-yield securities and investment
grade issues presents a very attractive opportunity for us to add
holdings with solid  fundamentals that will be well-positioned to
appreciate when credit spreads begin to tighten."

-- Blake E. Anderson, portfolio manager


In our search for higher-yielding lower-quality bonds, we discovered
opportunities in the health-care and transportation sectors. In the
health-care sector, hospital bonds have provided some of the best
opportunities recently. In fact, credit spreads have begun to tighten in
this sector and some of the fund's holdings have enjoyed solid price
appreciation. For example, in February, we purchased some Baa2-rated
bonds issued by the Johnson City, Tennessee Health & Educational
Facility Hospital Board (Mountain States Hospital), a well-managed
system that dominates its market. We were able to obtain these bonds at
exceptionally attractive yields. Among transportation issues, airline
bonds have provided the best opportunities as higher fuel prices and
uncertainty surrounding merger talks among United, U.S. Airways, and
American Airlines have led to widening credit spreads and bargain
prices. Nonetheless, airline financial fundamentals remain strong and
the fund's holdings are performing well.

* STAYING FLEXIBLE AMID UNCERTAINTY

Although our efforts to bring the fund's high-yield weighting closer to
that of its benchmark, duration remained relatively neutral as the fund
began fiscal 2001. The market seems to be looking for positive news such
as signs that the economy is slowing gradually. In the meantime, the
economy's strength and wide credit spreads make this a good time to add
attractively priced lower-quality bonds to the portfolio. This strategy
not only can help the fund's income stream but also should position the
fund to capture price  appreciation when credit spreads begin to shrink
again.

The views expressed here are exclusively those of Putnam Management.
They are not meant as investment advice. Although the described holdings
were viewed favorably as of 7/31/00, there is no guarantee the fund will
continue to hold these securities in the future. The lower credit rating
of high-yield bonds reflects a greater possibility that adverse changes
in the economy or poor performance by the issuers of these bonds may
affect the issuer's ability to pay principal and interest.


PERFORMANCE SUMMARY

This section provides information about your fund's performance, which
should always be considered in light of its investment strategy. Putnam
Tax-Free High Yield Fund is designed for investors seeking high current
income free from federal income tax through  investments primarily in
high-yield tax-exempt securities.

Past performance is not indicative of future results. More recent
returns may be worth more or less than those shown. Returns for class A
and class M shares reflect the current maximum initial sales charges of
4.75% and 3.25%, respectively. Class B share returns for the 1-, 5-,
10-year, and life of fund periods reflect the applicable contingent
deferred sales charge (CDSC), which is 5% in the first year, declines to
1% in the sixth year, and is eliminated thereafter. Returns shown for
class A and class M shares for periods prior to their inception are
derived from the historical performance of class B shares, adjusted in
the case of public offering price to reflect the initial sales charge
currently applicable to each class, but have not been adjusted to
reflect differences in expenses, which are lower for class A and M
shares than for class B shares. For class C shares, returns for periods
prior to their inception are derived from the historical performance of
class B shares, adjusted to reflect both the CDSC currently applicable
to class C shares, which is 1% for the first year and is eliminated
thereafter, and the higher operating expenses applicable to class C
shares. All returns assume reinvestment of distributions at NAV.
Investment return and principal value will fluctuate so that an
investor's shares when redeemed may be worth more or less than their
original cost.

Performance data represent past results, do not reflect future
performance, and will differ for each share class. Investment returns
and principal value will fluctuate so that an investor's shares when
sold, may be worth more or less than their original cost. See first page
of performance section for performance calculation method.


TERMS AND DEFINITIONS

Total return shows how the value of the fund's shares changed over time,
assuming you held the shares through the entire period and reinvested
all distributions in the fund.

Class A shares are generally subject to 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.

Net asset value (NAV) is the value of all your fund's assets, minus any
liabilities, divided by the number of outstanding shares, not including
any initial or contingent deferred sales charge.

Public offering price (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance
figures shown here assume the 4.75% maximum sales charge for class A
shares 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.


COMPARATIVE BENCHMARKS

Lehman Brothers Municipal Bond Index is an unmanaged list of long-term
fixed-rate investment-grade tax-exempt bonds  representative of the
municipal bond market. The index assumes reinvestment of all
distributions and interest payments and does not take into account
brokerage fees or taxes. Securities in the fund do not match those in
the index and  performance of the fund will differ. It is not possible
to invest directly in an index.

Consumer price index (CPI) is a commonly used measure of  inflation; it
does not represent an investment return.


A GUIDE TO THE FINANCIAL STATEMENTS

These sections of the report, preceded by the Report of independent
accountants, 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
for the reporting period. This is determined by adding up all the fund's
earnings -- from dividends and interest income -- and subtracting its
operating expenses. This statement also lists any net gain or loss the
fund realized on the sales of its holdings and -- for holdings that
remain in the portfolio -- any change in unrealized gains or losses over
the period.

Statement of changes in net assets  shows how the fund's net assets were
affected 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 ACCOUNTANTS
For the fiscal year ended July 31, 2000

To the Trustees and Shareholders of
Putnam Tax-Free High Yield Fund
(a series of Putnam Tax-Free Income Trust)

In our opinion, the accompanying statement of assets and  liabilities,
including the fund's portfolio (except for bond  ratings), 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, 2000, and the results of its operations, the changes in its net
assets and the financial highlights for the periods indicated, in
conformity with accounting principles generally accepted in the United
States. 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 auditing standards
generally accepted in the United States, which 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,
2000, by correspondence with the custodian, provide a  reasonable basis
for the opinion expressed above.

  (a) Percentages indicated are based on net assets of $1,573,705,196.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to
      be the most recent ratings available at July 31, 2000 for the securities
      listed. Ratings are generally ascribed to securities at the time of
      issuance. While the agencies may from time to time revise such ratings,
      they undertake no obligation to do so, and the ratings do not
      necessarily represent what the agencies would ascribe to these
      securities at July 31, 2000. Securities rated by Putnam are indicated by
      "/P" and are not publicly rated. Ratings are not covered by the Report
      of independent accountants.

  (b) The aggregate identified cost on a tax basis is $1,581,894,853,
      resulting in gross unrealized appreciation and depreciation of
      $59,874,886 and $84,843,966, respectively, or net unrealized
      depreciation of $24,969,080

(NON) Non-income-producing security.

(RES) Restricted, excluding 144A securities, as to public resale. The
      total market value of restricted securities held at July 31, 2000 was
      $221,822,401 or 14.1% of net assets.

(SEG) A portion of these securities were pledged and segregated with the
      custodian to cover margin requirements for futures contracts at July 31,
      2000.

      144A after the name of a security represents those exempt from
      registration under Rule 144A of the Securities Act of 1933. These
      securities may be resold in transactions exempt from registration,
      normally to qualified institutional buyers.

      The rates shown on IFB and IF COP, which are securities paying
      interest rates that vary inversely to changes in the market interest
      rates, FRB's and VRDN's are the current interest rates at July 31, 2000.

      The fund had the following industry group concentrations greater
      than 10% at July 31,2000 (as a percentage of net assets):

NOTES TO FINANCIAL STATEMENTS
July 31, 2000

Note 1
Significant accounting policies

Putnam Tax-Free High Yield Fund (the "fund") is a series of Putnam
Tax-Free Income Trust (the "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, Inc.
("Putnam Management") the fund's manager, a wholly-owned subsidiary of
Putnam Investments, Inc., believes does not involve undue risk to income
or principal.

The fund offers class A, class B, class C and class M shares. Class A
shares are sold with a maximum front-end sales charge of 4.75%. Class B
shares, which convert to class A shares after approximately eight years,
do not pay a front-end sales charge but pay a higher ongoing
distribution fee than class A shares, and are subject to a contingent
deferred sales charge, if those shares are redeemed within six years of
purchase. Class C shares have a higher ongoing distribution fee than
class B shares and have a one-year 1.00% contingent deferred sales
charge and do not convert to Class A shares. Class M shares are sold
with a maximum front end sales charge of 3.25% and pay an ongoing
distribution fee that is higher than class A shares but lower than class
B and class C shares.

Expenses of the fund are borne pro-rata by the holders of each class of
shares, except that each class bears expenses unique to that class
(including the distribution fees applicable to such class). Each class
votes as a class only with respect to its own distribution plan or other
matters on which a class vote is required by law or determined by the
Trustees. Shares of each class would receive their pro-rata share of the
net assets of the fund, if the fund were liquidated. In addition, the
Trustees declare separate dividends on each class of shares.

The following is a summary of significant accounting policies
consistently followed by the fund in the preparation of its financial
statements. The preparation of financial statements is in conformity
with generally accepted accounting principles and requires management to
make estimates and assumptions that affect the reported amounts of
assets and liabilities of 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 stated on the basis
of valuations provided by a pricing service, approved by the Trustees,
which uses information with respect to transactions in bonds, quotations
from bond dealers, market transactions in comparable securities and
various relationships between securities in determining value.
Restricted securities are stated at fair value following procedures
approved by the Trustees. Such valuations and procedures are reviewed
periodically by the Trustees. Short-term investments having remaining
maturities of 60 days or less are stated at amortized cost, which
approximates market value.

B) Security transactions and related investment income Security
transactions are accounted for 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.

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. 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.

Futures contracts are valued at the quoted daily settlement prices
established by the exchange on which they trade. 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.

D) Line of credit The fund has entered into a committed line of credit
with certain banks. This line of credit agreement includes restrictions
that the fund maintains an asset coverage ratio of at least 300% and
borrowings must not exceed prospectus limitations. For the year ended
July 31, 2000, the fund had no borrowings against the line of credit.

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 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 Internal Revenue Code of 1986, 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 2000, the fund had a capital loss carryover of approximately
$89,456,000 available to offset future capital gains, if any. The amount
of the carryover and the expiration dates are:

Loss Carryover    Expiration
--------------    ------------------
   $24,429,000    July 31, 2003
    12,477,000    July 31, 2004
    21,345,000    July 31, 2006
    23,391,000    July 31, 2007
     7,814,000    July 31, 2008

F) Distributions to shareholders Income dividends are recorded daily by
the fund and are distributed monthly. Capital gain distributions, 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 post-October loss deferrals,
dividends payable, defaulted bond interest, 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,
2000, the fund reclassified $132,626 to increase undistributed net
investment income and $132,626 to increase accumulated net realized
loss. The calculation of net investment income per share in the
financial highlights table excludes these adjustments.

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.

H) Amortization of bond premium and accretion of bond discount Any
premium resulting from the purchase of securities in excess of maturity
value is amortized on a yield-to-maturity basis. The premium in excess
of the call price, if any, is amortized to the call date; thereafter,
the remaining excess premium is amortized to maturity. Discounts on zero
coupon bonds and original issue discount bonds are accreted according to
the yield-to-maturity basis.

Note 2
Management fee, administrative
services and other transactions

Compensation of Putnam Management, for management and investment
advisory services is paid quarterly based on the average net assets of
the fund. Such fee is 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% next $500 million, 0.45% of the next $5 billion, 0.425%
of the next $5 billion, 0.405% of the next $5 billion, 0.39% of the next
$5 billion, and 0.38% thereafter.

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 Investments, Inc.
Investor servicing agent functions are provided by Putnam Investor
Services, a division of PFTC.

Under the subcustodian contract between the subcustodian bank and PFTC,
the subcustodian bank has a lien on the securities of the fund to the
extent permitted by the fund's investment restrictions to cover any
advances made by the subcustodian bank for the settlement of securities
purchased by the fund. At July 31, 2000, the payable to the subcustodian
bank represents the amount due for cash advance for the settlement of a
security purchased.

For the year ended July 31, 2000, fund expenses were reduced by $307,042
under expense offset arrangements with PFTC. Investor servicing and
custodian fees reported in the Statement of operations exclude these
credits. The fund could have invested a portion of the assets utilized
in connection with the expense-offset arrangements in an
income-producing asset if it had not entered into such arrangements.

Each Trustee of the fund receives an annual Trustee fee, of which $1,515
has been allocated to the fund, and an additional fee for each Trustees
meeting attended. Trustees receive additional fees for attendance at
certain committee meetings.

The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan")
which allows the Trustees to defer the receipt of all or a portion of
Trustees Fees payable on or after July 1, 1995. The deferred fees remain
invested in certain Putnam funds until distribution in accordance with
the Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension
plan (the "Pension Plan") covering all Trustees of the fund who have
served as a Trustee for at least five years. Benefits under the Pension
Plan are equal to 50% of the Trustee's average total retainer and
meeting fees for the three years preceding retirement. Pension expense
for the fund is included in Compensation of Trustees in the Statement of
operations. Accrued pension liability is included in Payable for
compensation of Trustees in the Statement of assets and liabilities.

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, Inc., a wholly owned subsidiary of
Putnam Investments Inc., for services provided and expenses incurred by
it in distributing shares of the fund. The Plans provide for payments by
the fund to Putnam Retail Management, Inc. at an annual rate 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 an annual rate of 0.20%, 0.80%,
1.00% and 0.50% of the average net assets attributable to class A, class
B, class C and class M shares respectively. Prior to September 14, 1999,
the Trustees had approved payment by the fund at an annual rate of 0.70%
of the average net assets attributable to class B shares.

For the year ended July 31, 2000, Putnam Retail Management, Inc., acting
as underwriter received net commissions of $60,937 and $1,460 from the
sale of class A and class M shares, respectively, and received
$1,383,162 and $4,519 in contingent deferred sales charges from
redemptions of class B and class C shares, respectively. A deferred
sales charge of up to 1% is assessed on certain redemptions of class A
shares. For the year ended July 31, 2000, Putnam Retail Management,
Inc., acting as underwriter received $18,293 on class A redemptions.

Note 3
Purchases and sales of securities

For the year ended July 31, 2000, cost of purchases and proceeds from
sales of investment securities other than short-term investments
aggregated $203,493,477 and $443,118,169, respectively. There were no
purchases and sales of U.S. government obligations.

Note 4

At July 31, 2000, there was an unlimited number of shares of beneficial
interest authorized. Transactions in capital shares were as follows:
