Dear Shareholder:

Risk-averse investors became more adventuresome in recent months and began
to retreat from the relative security of U.S. Treasury bonds. As prices on
these and other taxable bonds declined, their yields rose. The exodus
accelerated somewhat following Federal Reserve Board Chairman Alan
Greenspan's comments in July that tighter monetary policy might help stave
off inflation.

Since this shift in investor mood had a relatively mild impact on
tax-exempt bonds, the result was a slight widening in the yield spread
relative to taxable bonds. With the gap back around a more traditional 90%
- -- a modest retreat from earlier ratios of close to 100% -- municipal
bonds are now considered to be at fair value.

In this investment climate, Putnam Tax-Free Insured Fund's manager,
Richard Wyke, continues to place heavy emphasis on maximizing current
income while maintaining a portfolio as free of volatility as possible.
Rick explains his strategies in the following review of your fund's
performance during the fiscal year that ended on July 31, 1999.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
September 15, 1999



Report from the Fund Manager

Richard P. Wyke

Considerable change has taken place in the municipal bond environment
since the midpoint of Putnam Tax-Free Insured Fund's 1999 fiscal year. In
our semiannual report, we commented on a relatively quiet year in the
municipal market, dominated by bargain prices and high yields compared to
Treasury yields. Lately the bond markets (including municipals) have been
under pressure because of concerns about rising interest rates and
inflation. While rising rates have a negative effect on bond prices,
dragging down short-term total return performance, they do provide an
opportunity to potentially lock in higher yields and increase the
portfolio's income over time. The impact of rising interest rates on your
fund's total return for the 12 months ended July 31, 1999, can be seen in
the table below.

* FED POLICY AFFECTS YIELD CURVE

Given the strength of the economy and Federal Reserve Board Chairman Alan
Greenspan's comments to Congress on June 22 implying that interest rates
could rise again, we focused on reducing volatility in the portfolio as
well as providing a steady flow of tax-free income. Although Greenspan
made it clear that the Fed did not see signs of inflation (the bond
market's enemy), he felt it might be prudent to take back the three
interest-rate cuts that occurred in late 1998. While his statements were
balanced and lacked any crisis tone, the market responded negatively,
forcing interest rates upward.

*Based on net assets as of 7/31/99. Holdings will vary over time.


Climbing interest rates and hospital credit woes continued to take their
toll on new-issue volume of municipal bonds as the national supply fell
approximately 25% in comparison to the first half of 1998. However, we
have seen continued healthy demand for municipal bonds, which provided
strong technical support for the municipal bond market and helped support
bond prices.

For most of the fiscal year, we saw opportunity in intermediate-term bonds
(8 to 15 years), but the lack of demand from insurance companies (the
primary buyers of intermediate bonds) held their performance back. Then,
at the end of June (and again in mid August, shortly after the close of
fiscal 1999), the Fed tightened short-term interest rates, each by a
quarter of a percentage point. These moves flattened the shape of the
yield curve at the shorter end and created more value for intermediate
bonds relative to longer-term bonds. A flatter yield curve means that the
difference between short- and long-term rates is relatively small.


"While rising rates have a negative effect on bond prices, dragging down
short-term total return performance, they do provide an opportunity to
potentially lock in higher yields and increase the portfolio's income over
time."

- -- Richard P. Wyke, Fund manager


The reward for extending maturities is small as well, and more investors
prefer to stay in the short and intermediate ranges of the curve. We
anticipate that this pattern will hold and look forward to better
performance from intermediate bonds in the future.

* NEW ACQUISITIONS INCREASE CALL PROTECTION

Call protection seeks to keep higher-yielding bonds in the portfolio for a
longer period of time. There are a few ways to protect the bonds in the
portfolio from being called away. One way to is to buy discount bonds with
low coupon rates. This strategy confers a certain amount of call
protection because these bonds are less likely to be refinanced by the
issuer. Another way to increase call protection is to purchase noncallable
bonds or bonds with distant call dates.

One example of a newly acquired noncallable bond is the Cook County,
Illinois, general obligation bonds that mature in 2008. Also during the
period, at a discount we purchased Portland, Oregon, sewer system revenue
bonds, which mature in 2012. While these holdings and others discussed in
this report were viewed favorably at the end of the period, all are
subject to review in accordance with the fund's investment strategy and
may vary in the future.

Reimbursement and regulatory concerns have hurt some of the credit ratings
of issuers within the health-care industry. However, there are some
attractive fundamental values in this sector that make health-care
holdings like the Fredericksburg, Virginia, revenue bonds valuable
contributors to performance. The health-care industry is a good example of
a sector in which bond insurance -- which reduces risk by assuring the
timely payment of principal and interest of the bonds -- is especially
beneficial.

* VOLATILITY EXPECTED NEAR TERM, FOLLOWED BY IMPROVED OUTLOOK

In summary, there are many high-profile issues to be concerned about that
may affect the bond markets: inflationary and Fed fears and irrational
reactions to the arrival of the year 2000 (Y2K). After much research, we
believe that a sharp reaction in the markets to Y2K is not warranted by
the fundamentals and is not a likely event.

The rise in interest rates over the past few months is a normal reaction
to fears of inflation and an overheated economy. While such an environment
is not ideal, it is part of the cyclical nature of the financial markets
and one of the reasons we have always advised shareholders to diversify
their investments. Interest rates are likely to trend higher over the next
several months, but over the longer term we believe that inflation will be
held in check by the Fed's vigilant stance. Interest rates should
eventually decline, providing a positive environment for future
performance.

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 7/31/99, 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 no assurance of future results. More recent returns
may be 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-, and 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 A 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.

</TABLE>


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.

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 is determined. All investment and non-investment assets are
added together. Any unpaid expenses and other liabilities are subtracted
from this total. The result is divided by the number of shares to
determine the net asset value per share, which is calculated separately
for each class of shares. (For funds with preferred shares, the amount
subtracted from total assets includes the 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-ended funds, a separate
table is provided for each share class.



Report of independent accountants
For the fiscal year ended July 31, 1999

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 portfolio of investments owned (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, 1999, and the results of its operations, the changes in its net assets
and the financial highlights for the periods indicated, in conformity with
generally accepted accounting principles. 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
generally accepted auditing standards 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,
1999 by correspondence with the custodian, provide a reasonable basis for
the opinion expressed above.

Notes to financial statements
July 31, 1999

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. The fund
began offering class C shares on July 26, 1999. 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 pay
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. 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.

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). Gain or loss 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, 1999, 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, 1999, the fund had a capital loss carryover of approximately
$468,000 available to offset future net capital gain, if any, which will
expire on July 31, 2007.

F) Distributions to shareholders Distributions to shareholders from net
investment income are recorded by the fund on the ex-dividend date.
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, and
unrealized gains and losses on certain futures contracts.
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,
1999, the fund reclassified $36,521 to increase distributions in excess of
net investment income and $36,521 to decrease distributions in excess of
gains on investments. 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 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 on 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. On June 4,
1999, the Trustees approved a management fee schedule to become effective
July 1, 1999, based upon the lesser of (i) an annual rate of 0.50% of the
average net asset value of the fund or (ii) the initial tiers mentioned
above.

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.

As part of 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, 1999, 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, 1999, fund expenses were reduced by $164,318
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 $845 has
been allocated to the fund, and an additional fee for each Trustee's
meeting attended. Trustees who are not interested persons of Putnam
Management and who serve on committees of the 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 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 Mutual Funds Corp., 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 Mutual Funds Corp. at annual rates 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 to an annual rate of 0.20%, 1.00% and 0.50% of the
average net assets attributable to class A, class C and class M shares,
respectively. Effective April 21, 1999, the Trustees approved
reinstatement of payment by the fund to an annual rate of 0.60% of the
average net assets attributable to class B shares.

For the year ended July 31, 1999, Putnam Mutual Funds Corp., acting as
underwriter received net commissions of $32,325 and $1,398 from the sale
of class A and class M shares, respectively and $371,865 and no monies in
contingent deferred sales charges from redemptions of class B and class C
shares. A deferred sales charge of up to 1% is assessed on certain
redemptions of class A shares. For the year ended July 31, 1999, Putnam
Mutual Funds Corp., acting as underwriter received $9,702 on class A
redemptions.

Note 3
Purchase and sales of securities

During the year ended July 31, 1999, cost of purchases and proceeds from
sales of investment securities other than short-term investments
aggregated $244,450,558 and $205,954,639, respectively. There were no
purchases and sales of U.S. government obligations.
