* Performance data represent past results. 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. The fund began operations
September 9, 1985, offering shares now known as class B. On September 20,
1993, the fund began offering class A shares. Performance for each share
class will differ.

Terms you need to know
Total return is the change in value of an investment from the beginning to
the end of a period, assuming the reinvestment of all distributions. It may
be shown at net asset value or at public offering price.
Net asset value (NAV) is the value of all your fund's assets, minus any
liabilities, divided by the number of outstanding shares, not reflecting any
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.
Contingent deferred sales charge (CDSC) is a charge applied at the time of
the redemption of shares rather than the time of purchase. It generally
declines and eventually disappears over a stated period.
Class A shares are the shares of your fund offered subject to an initial
sales charge. Your fund's POP includes the maximum 4.75% sales charge.
Class B shares are the shares of your fund offered with no initial sales
charge. Within the first six years of purchase, they are subject to a CDSC
declining from 5% to 1%. After the sixth year, the CDSC no longer applies.
Current dividend rate is calculated by annualizing the net investment income
paid to shareholders in the fund's most recent distribution, then dividing by
the NAV or POP on the last day of the period.
Current 30-day yield, based only on the fund's net investment income
earnings, is calculated in accordance with Securities and Exchange Commission
guidelines.
Taxable equivalent return is the rate at which a taxable investment would
have to generate income to equal the fund's current dividend rate or yield.

Chairman of the Trustees
(C) Karsh, Ottawa
Dear Shareholder:
In the six months ended January 31, 1994, Putnam Tax-Free Insured Fund
continued to provide attractive tax-free income and total return performance
with its portfolio of high-quality investments. The portfolio quality is
reflected in the fund's AAAf rating from Standard & Poor's,(R) the highest
available for a mutual fund.
The past six months have been characterized by modest growth in the U.S.
economy, low interest rates, and a low rate of inflation. Amid this
encouraging investment environment, the municipal bond market flourished,
delivering some of its strongest performance in decades. Your fund's
proactive strategy of timely trading based on relative values and regional
supply/demand imbalances enabled it to benefit fully from these market
conditions.
In closing, I would like to draw your attention to the new format of this
report. Previous reports contained information on both of the portfolios that
compose Putnam Tax-Free Income Trust: Putnam Tax-Free High Yield Fund and
Putnam Tax-Free Insured Fund. Now, each fund will publish its own report,
thereby saving shareholders of only one fund the time and trouble of sorting
through information not directly related to their investment.
The following Report from Putnam Management contains fund manager Richard
Wyke's overview of the past six months and his insight into what
lies ahead.
Respectfully yours,
(SIGNATURE)

Report from
Putnam Management
Building on its well-established record of dependable performance, Putnam
Tax-Free Insured Fund provided shareholders with solid tax-free income over
the six-month period ended January 31, 1994. At the same time, the fund
maintained its superior AAAf rating from Standard & Poor's, providing a
measure of security for quality-conscious investors. This is the highest
possible rating for a mutual fund based on the S&P(R) assessment of portfolio
quality. Of course, it does not guarantee the fund's market value nor
constitute approval of the shares.
The current dividend rate for class B shares on January 31, 1994, was 4.61%,
based on net asset value. For an investor in the new maximum 39.6% federal
tax bracket,* a fully taxable investment would have had to earn 7.63% to
equal the tax-free yields of this portfolio. Compare this level of after-tax
income with the 6.23% yield for 30-year Treasury bonds as of that date to
recognize the full advantage of tax-exempt investing.
Muni market strengthens The municipal bond market's strength remained in
evidence during the fund's semiannual period. The U.S. economy grew at a
moderate rate while inflation and interest rates remained low. The entire
fixed-income market responded positively to this environment, rallying almost
daily from June through September. Bond prices increased as yields on U.S.
Treasury securities reached 20-year lows, while yields on insured municipal
bonds, like those in which your fund invests, approached their lowest levels
in more than a decade.
In November and December, the Treasury market corrected. The insured
municipal bond market followed suit. Still, the relative value of municipal
securities was so compelling that in January these securities began to
outperform Treasuries on an after-tax basis. In fact as the semiannual period
drew to a close, municipal bond values actually began to appreciate from
their December lows while Treasury values remained flat.
High-quality portfolio An investment in a municipal bond mutual fund exposes
an investor to some risk, not the least of which is credit risk. Credit risk
involves the possibility that the issuer of a debt obligation will default.
Only the U.S. Treasury's bonds, notes, and bills are considered free of
credit risk.
The credit risk of this fund's holdings has been significantly reduced,
however. This fund invests in high-quality,
- ----------------------

although many could receive tax benefits from a fund investment. Consult your
tax advisor for more guidance.
<PAGE>
tax-exempt bonds and notes. Each security that we purchase is either rated
AAA, or backed by the full faith and credit of the U.S. government or covered
by insurance guaranteeing the timely payment of principal and interest. At
least 70% of the fund's holdings are insured.
Compelling dynamics The recent relative outperformance of municipal bonds
over U.S. Treasuries has been rooted largely in a favorable supply/demand
relationship. For more than two years, the supply of municipal bonds has
surged as municipalities took advantage of low interest rates, to refinance
existing debt issued at higher interest rates.
In January 1994, the pace of this refinancing finally began to slow. At the
same time, investor demand for municipal bonds has continued to grow. With so
many other shelters now gone, municipal bonds have become one of the last tax
refuges for investment income. Their current after-tax yield advantage has
further increased investor demand. The resulting imbalance helped boost bond
prices, and in turn, the fund's net asset value, throughout the period.

Regional opportunities Regional supply/demand relationships continue to play
an important role in our investment strategy. For example, over the past six
months, we discovered some excellent values in California-insured municipal
securities. Abundant supply made these securities particularly attractive,
and the growing appetite of California investors for insured investments
should make these securities strong performers in the months ahead.
Our recent California securities purchase also highlights a new strategy of
seeking investments in states with higher taxes and where we expect higher
investor demand for tax-free income. If, as we expect, the supply of
municipal securities wanes, insured bonds issued by higher-tax, high-demand
states should perform particularly well. Thus far, we have found such
opportunities only in California. However, we are currently evaluating
investments with similar characteristics in New York, Minnesota, and Florida.
<PAGE>
Looking ahead We are maintaining our positive outlook for the municipal bond
market as a whole. Although there can never be any assurance, the market's
shift in the supply/demand balance toward higher demand should lead to strong
performance by insured bonds, especially those from higher-tax states and a
continuation of the relative advantage of tax-free yields over yields on
comparable taxable investments.
Going forward, we expect more of an income emphasis--reflecting the
beginnings of a trend toward higher interest rates. Rates began moving upward
after the end of the semiannual period and, while they may go somewhat
higher, there seems to be no serious inflationary threat driving the shift.
In this climate, municipal bonds should continue to provide solid income but
not the significant price appreciation we have seen in recent years. Your
fund's emphasis on regions and states with favorable supply/demand dynamics
and its somewhat higher-yielding portfolio position it well for what we see
ahead.

per class A and class B share of $15.79 and $15.80, respectively.
(b) The Moody's or Standard & Poor's ratings indicated are believed to be the most recent ratings available at
January 31, 1994, 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 January 31,
1994. Securities rated by Putnam are indicated by "/P" and are not publicly rated.

1994. The market value of segregated securities with the custodian for transactions on futures contracts is
$18,220,000.
(d) Restricted as to public resale. At the date of acquisition, these securities were valued at
cost. There were no outstanding unrestricted securities of the same class as those held. Total market value of
restricted securities owned at January 31, 1994 was $22,615,000, or 3.7% of net assets.
(e) The aggregate identified cost on a tax basis is $549,137,517, resulting in gross unrealized appreciation of
$62,021,225, and $289,806, respectively, or net unrealized appreciation of $61,731,419.
The rates shown on Variable Rate Demand Notes and Residual Interest Bonds are the current interest rates at
January 31, 1994, which are subject to change based on the terms of the security.

Notes to
financial statements
January 31, 1994 (Unaudited)
Note 1 Significant accounting policies
The Fund is a series of Putnam Tax-Free Income Trust which is registered
under the Investment Company Act of 1940, as amended, as a diversified,
open-end management investment company. Putnam Tax-Free Insured Fund seeks
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 both Class A and Class B shares. The Fund commenced its
public offering of Class A shares on September 20, 1993. Class A shares are
sold with a front-end sales charge of 4.75%. Class B shares 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. In addition, the Trustees
declare separate dividends on each class of shares. Each class bears expenses
unique to that class (including the distribution fees applicable to such
class), and votes as a class only with respect to its own distribution plan
or other matters on which a class vote is required by law to be determined by
the Trustees, all other expenses of the Fund are borne pro-rata by the
holders of both classes of shares. 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
policies are in conformity with generally accepted accounting principles.
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.
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). Interest income is recorded on the accrual basis.
C) Option accounting principles When the Fund writes a call or put option, an
amount equal to the premium received by the Fund is included in the Fund's
"Statement of Assets and Liabilities" as an asset and an equivalent
liability. The amount of the liability is subsequently "marked-to-market" to
reflect the current market value of the option written. The current market
value of an option is the last sale price or, in the absence of a sale, the
last offering price. If an option expires on its stipulated expiration date,
or if the Fund enters into a closing purchase transaction, the Fund realizes
a gain (or loss if the cost of a closing purchase transaction exceeds the
premium received when the option was written) without regard to any
unrealized gain or loss on the underlying security, and the liability related
to such option is extinguished. If a written call option is exercised, the
Fund realizes a gain or loss from the sale of the underlying security and the
proceeds of the sale are increased by the premium originally received. If a
written put option is exercised, the amount of the premium originally
received reduces the cost of the security the Fund purchases upon exercise of
the option.
The Fund writes covered call options; that is, options for which it holds the
underlying security or its equivalent. Accordingly, the risk in writing a
call option is that the Fund relinquishes the opportunity to profit if the
market price of the underlying security increases and the option is
exercised. In writing a put option, the Fund assumes the risk of incurring a
loss if the market price of the underlying security decreases and the option
is exercised.
The premium paid by the Fund for the purchase of a call or put option is
included in the Fund's "Statement of Assets and Liabilities" as an investment
and subsequently "marked-to-market" to reflect the current market value of
the option. If an option which the Fund has purchased expires on the
stipulated expiration date, the Fund realizes a loss in the amount of the
cost of the option. If the Fund enters into a closing sale transaction, the
Fund realizes a gain or loss, depending on whether proceeds from the closing
sale transaction are greater or less than the cost of the option. If the Fund
exercises a call option, the cost of the securities acquired by exercising
the call is increased by the premium paid to buy the call. If the Fund
exercises a put option, it realizes a gain or loss from the sale of the
underlying security and the proceeds from such sale are decreased by the
premium originally paid.
<PAGE>
Futures A futures contract is an agreement between two parties to buy and
sell a security at a set price on a future date. Upon entering into such a
contract, the Fund is required to pledge to the broker an amount of cash or
U.S. government securities equal to the minimum "initial margin" requirements
of the exchange. Pursuant to the contract, the Fund agrees to receive from or
pay to the broker an amount of cash equal to the daily fluctuation in value
of the contract. Such receipts or payments are known as "variation margin,"
and are recorded by the Fund as unrealized gains or losses. 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. The potential risk to the Fund is that the change in
value of the underlying securities may not correspond to the change in value
of the futures contracts.
Options on futures Options on futures generally operate in the same manner as
options purchased or written directly on the underlying debt securities. The
Fund is required to deposit, in a manner similar to futures contracts,
"initial margin" and "variation margin" with respect to put and call options
written on futures contracts. In addition, upon exercise, net premiums will
decrease the unrealized loss or increase the unrealized gain on the future.
D) Federal taxes It is the policy of each 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. Therefore, no provision has been made for federal taxes on income,
capital gains or unrealized appreciation of securities held or excise tax on
income and capital gains.
E) Distributions to shareholders Income dividends are recorded daily by the
Fund and are distributed monthly. Capital gain distributions are recorded on
the ex-dividend date and paid annually, or as necessary to meet the
distribution requirements described above.
F) Amortization of bond premium and discount Any premium resulting from the
purchase of securities is amortized using the effective yield method for
bonds issued after September 27, 1985, and on a straight-line basis for bonds
issued prior thereto. 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. Discount on zero-coupon bonds is amortized according
to the effective yield method.
G) Expenses of the Trust Expenses directly charged or attributable to the
Fund will be paid from the assets of the Fund. Generally, expenses of the
Trust will be allocated between 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
Compensation of Putnam Investment 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 for the quarter. Such fee is based on 0.6% of the first
$500 million of average net assets; 0.5% of the next $500 million; 0.45% of
the next $500 million and 0.4% of any amount over $1.5 billion. Such fees are
subject to reduction under current law in any year to the extent that
expenses (exclusive of distribution fees, brokerage, interest and taxes) of
the Fund exceed 2.5% of the first $30 million of average net assets, 2.0% of
the next $70 million and 1.5% of any excess over $100 million and by the
amount of certain brokerage commissions and fees (less expenses) received by
affiliates of the Manager on the Fund's portfolio transactions.
The Fund also reimburses the Manager 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. For the six months
ended January 31, 1994, the Fund paid $9,187 for these services.
Trustees of the Fund receive an annual Trustee's fee of $1,270, and an
additional fee for each Trustees' meeting attended. Trustees who are not
interested persons of the Manager and who serve on committees of the Trustees
receive additional fees for attendance at certain committee meetings.
Custodial functions are being provided to the Fund by Putnam Fiduciary Trust
Company (PFTC), a subsidiary of Putnam Invest-
<PAGE>
ments, Inc. Investor servicing agent functions are provided by Putnam
Investor Services, a division of PFTC. Fees paid for these investor servicing
and custodian fees functions for the six months ended January 31, 1994
amounted to $259,010. Investor servicing and custodian fees reported in the
Statement of operations for the six months ended January 31, 1994 have been
reduced by credits allowed by PFTC.
The Fund has adopted a distribution plan with respect to its Class A shares
(the "Class A Plan") pursuant to Rule 12b-1 under the Investment Company Act
of 1940. The purpose of Class A Plan is to compensate Putnam Mutual Funds
Corp. (formerly known as Putnam Financial Services, Inc.), a wholly-owned
subsidiary of Putnam Investments, Inc., for services provided and expenses
incurred by it in distributing Class A shares. The Trustees have approved
payment by the Fund to Putnam Mutual Funds Corp. at an annual rate of up to
0.20% of the Fund's average net assets attributable to Class A shares. For
the six months ended January 31, 1994, the Fund paid Putnam Mutual Funds
Corp. distribution fees of $150,638, for Class A shares.
The Fund has adopted a separate distribution plan with respect to its Class B
shares (the "Class B Plan") pursuant to Rule 12b-1 under the Investment
Company Act of 1940. The purpose of the Class B Plan is to compensate Putnam
Mutual Funds Corp. for services provided and expenses incurred by it in
distributing Class B shares. The Class B Plan provides for payments by the
Fund to Putnam Mutual Funds Corp. at an annual rate of up to 0.85% of the
funds average net assets attributable to Class B shares. For the six months
ended January 31, 1994, the Fund paid Putnam Mutual Funds Corp. distribution
fees of $2,068,052 for Class B shares.
During the six months ended January 31, 1994, Putnam Mutual Funds Corp., a
whollyowned subsidiary of Putnam Investments, Inc., acting as an underwriter,
received net commissions of $21,860 from the sale of Class A shares of the
Fund.
Putnam Mutual Funds Corp. also receives the proceeds of contingent deferred
sales charges levied on Class B share redemptions within four years of
purchase. The charge is based on declining rates, which begin at 5.0% of the
net asset value of the redeemed shares . Putnam Mutual Funds Corp. received
contingent deferred sales charges of $370,307 from such redemptions for the
six months ended January 31, 1994.
A deferred sales charge of up to 1% is assessed on certain redemptions of
Class A shares purchased as part of an investment of $1 million or more. For
the six months ended January 31, 1994, Putnam Mutual Funds Corp., acting as
underwriter, received no monies on Class A redemptions.
Note 3 Purchases and sales of securities
During the six months ended January 31, 1994, purchases and sales of
investment securities other than short-term municipal obligations aggregated
$134,075,069 and $110,688,155, respectively. Purchases and sales of
short-term municipal obligations aggregated $29,360,000 and $19,060,000
respectively. In determining the net gain or loss on securities sold, the
cost of securities has been determined on the identified cost basis.

Note 5 Reclassification of Capital Accounts
Effective August 1, 1993, Putnam Tax-Free Income Trust--Putnam Tax-Free
Insured Fund has adopted the provisions of Statement of Position 93-2
"Determination, Disclosure and Financial Statement Presentation of Income,
Capital Gain and Return of Capital Distributions by Investment Companies
(SOP)." The purpose of this SOP is to report the accumulated net investment
income (loss) and accumulated net realized gain (loss) accounts in such a
manner as to approximate amounts available for future distributions (or to
offset future realized capital gains) and to achieve uniformity in the
presentation of distributions by investment companies.
As a result of the SOP, the Fund has reclassified $1,285,900 reducing
distributions in excess of net investment income, $1,031,356 reducing
accumulated net realized loss and $2,317,256 decreasing additional paid-in
capital.
These adjustments represent the cumulative amounts necessary to report these
balances through July 31, 1993, the close of the Fund most recent fiscal
year-end, for financial reporting and tax purposes.

Fund
Performance
Supplement
Putnam Tax-Free Insured Fund is one of two separate portfolios composing
Putnam Tax-Free Income Trust, a series investment company. Each portfolio
seeks high current income exempt from federal income tax, consistent with its
particular investment policies. Putnam Tax-Free Insured Fund invests in
tax-exempt securities covered by insurance guaranteeing the timely payment of
principal and interest, but not market value, uninsured securities rated AAA
or Aaa, or securities backed by the U.S. government.
The Lehman Brothers Municipal Bond Index is an unmanaged list of
approximately 8,000 investment-grade, fixed rate, long-term maturity
tax-exempt bonds, which are selected to be representative of the market in
terms of price movement and sector distribution. The average quality of bonds
held in the index may differ from the average quality of those bonds in which
the fund invests. The index does not include bonds in certain of the lower
rating classifications in which the fund may invest. The index does not take
into account brokerage commissions or other costs and may pose different
risks from the fund. Total return performance for the index reflects
mathematically derived changes of market price and reinvestment of interest
payments, as computed by Lehman Brothers. The fund portfolio contains
securities that do not match those in the index.
The Consumer Price Index is a commonly used measure of inflation; it does not
represent an investment return.
The fund performance supplement has been prepared by Putnam Management to
provide additional information about the fund and the indexes used for
performance comparisons. The information is not part of the portfolio of
investments owned or the financial statements.
