Dear Shareholder:

The markets continued to provide their share of challenges and
opportunities as your fund closed its books on the first half of fiscal
2000. In the following report, the fund manager discusses performance for
the period and prospects for the months ahead.

This is the last letter to you and the other shareholders of Putnam
Tax-Free High Yield Fund that I will be signing. After more than 30 years
as Chairman of the Trustees and President of the Putnam Funds, the time
has come for me to step aside. In June, John Hill will become Chairman.
John is currently an independent Trustee and has served on the board for
the past 14 years. In addition, my son, George Putnam, III, will take on
the role of President. I am confident that the leadership of the funds
will be in exceptionally strong hands.

I will become Chairman Emeritus, remain a Putnam shareholder, and stay in
close touch with the funds. It has been my privilege to serve you.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
March 15, 2000


Report from the Fund Manager

Blake E. Anderson

Two of the bond market's worst enemies -- a strong economy and rising
interest rates -- played havoc with municipal bond prices over the past
six months. This hostile environment created high volatility and pushed
bond prices down, resulting in negative returns for most bond funds,
including Putnam Tax-Free High Yield Fund. But the story does not end
there. The turbulence also created unique opportunities that helped your
fund deliver high levels of tax-free monthly income while allowing us to
add more high-yield municipal bonds to the portfolio at unusually
attractive prices. We believe these new acquisitions will serve the fund
well when the bond market environment becomes more favorable.

* MUNICIPAL YIELDS HIGH RELATIVE TO TREASURY BONDS

Despite the recent negative performance, municipal bonds currently offer
an unusually high yield relative to those available in the taxable
Treasury market. Tax-exempt bonds have always had lower yields than
Treasuries because of their tax-advantaged status. But because of the high
quality and concern over a shrinking supply in the Treasury market, the
rush to Treasuries has pushed their prices up and moved their yields
lower. As a result, the yield difference between the taxable and the
tax-free bond markets has become exceptionally narrow, sometimes
vanishing, making the latter extremely attractive to investors.

*Based on net assets as of 1/31/00. Holdings will vary over time.


Furthermore, higher interest rates last year discouraged municipalities
from issuing bonds or refunding outstanding bonds, a situation that
created a dearth. As we begin to see an increase in demand for this scant
supply, we expect that municipal bond prices could move higher later this
year.

* SHORTER MATURITIES, GOOD TIMING HELP PERFORMANCE

There are two key reasons why your fund came through a difficult year with
relatively few scars. First, the portfolio contained a lower percentage of
longer-term bonds than many of its peers. As you may know, when interest
rates are rising, longer-term bond prices, because of their implicit
higher risk, experience the steepest fall. Your fund's emphasis on bonds
with intermediate maturities in the 8- to 15-year range proved
advantageous and helped to protect the portfolio's value.

Second, as we continued to downgrade the overall credit quality of the
fund (to bring the fund's high-yield weighting closer to that of its
benchmark), our timing on the purchase of many new high-yield bonds was
efficient. For the most part, we held back when prices were too high and
bought when prices became cheaper. For the first time in a long while, we
believe credit risk is properly priced in this market, and once again we
are selectively buying lower-rated higher-yield credits.

  include unrated bonds considered by Putnam Management to be of comparable
  quality. Ratings will vary over time.


* HEALTH CARE, TRANSPORTATION, UTILITIES OFFER VALUE

The hospital/health-care sector remains one of the largest in this fund.
This sector is still going through a transformation that began with the
Medicare Balanced Budget Act of 1997 and has negatively affected hospital
revenues ever since. The situation grew worse with the excess of hospitals
and empty beds, the growth of managed care, and the many unsuccessful
acquisitions that took place in the past few years. All these events have
led to poor earnings and higher risk in this sector. But higher risk, if
selectively taken, can mean higher yields and opportunity. This is where
Putnam's analysts add their value. Up until now, the fund has owned fewer
health-care bonds than its peers, but our analysts believe that there is
currently justification for a more optimistic outlook. In 1999, we
witnessed the first Balanced Budget Relief Act and are expecting another
relief act in 2000 that will help increase revenues among hospitals. Given
the brightening picture and the belief that the market is somewhere near
the bottom in terms of bad news, we plan to increase holdings cautiously
in the health-care sector.


"If you've taken advantage of the tremendous bull run of the equity market,
offsetting your portfolio with tax-free investments is a smart choice."

- -- CNNfn, February 2, 2000


Within the transportation sector, we favor the airlines because they have
done a good job of keeping seats full and fares high. Currently the fund
holds revenue bonds backed by Northwest Airlines, Air Canada, United
Airlines, and U.S. Airways, among others. Airport revenue bonds also
continue to supply the portfolio with a steady stream of tax-exempt
income, as evidenced by our longstanding investments in bonds issued by
the Northwest Regional Airport and Denver City & County Airport.

High fuel prices and deregulation have made it difficult to navigate the
utility sector. Furthermore, unattractive bond structures with short call
dates have deterred us from delving heavily into this sector. Of course
there has been opportunity in utility bonds, but in this sector we
generally favor insured bonds, for which the insurance guarantees the
principal and interest payments. North Carolina Eastern Municipal Power
Agency is an example of a revenue bond that is insured by MBIA (Municipal
Bond Insurance Agency).

* AFTER DIFFICULT PERIOD, LONG-TERM OUTLOOK IMPROVING

After rising significantly in 1999, interest rates continued to climb in
the new year's first month. Just as importantly, the yield curve has
become inverted; short-term interest rates are now higher than long-term
interest rates. Historically such an inversion has been associated with a
slowdown of economic growth and a decline in core inflation over time. In
the meantime, the markets remain nervous about inflation, especially with
prices of oil and other commodities rising sharply.

Inflationary concerns, accompanied by the expectation of further
tightening by the Federal Reserve Board, should help keep municipal bond
prices in a narrow range in the months ahead. However, once the Fed's
interest-rate increases have their intended effect of slowing the economic
pace, we believe that the municipal bond market will react positively and
yields will begin to trend lower. Meanwhile, we will continue to focus on
expanding the fund's high-yield allocation as long as we believe prices in
this sector offer suitable compensation for its higher risk level. If we
do not believe the pricing is right, then we will wait for better deals.
It is our opinion that as the economy eventually cools off, your fund will
be well positioned to offer strong 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 1/31/00, 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- and 5-year 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.

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 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.

      at January 31, 2000 was $185,265,080 or 11.1% of net assets.

(SEG) A portion of these securities were pledged and segregated with the custodian to cover margin requirements for

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 are subject to the same fees and expenses as class B shares, except
that class C shares 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 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 that 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
at the date 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. Short-term
investments are stated at amortized cost, which approximates market value,
and 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). 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 six months
ended January 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, 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
$81,642,000 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

F) Distributions to shareholders 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. 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.

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 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% of
the next $500 million, 0.45% of the next $5 billion, 0.425% of the next $5
billion, 0.405% of the next $5 billion, 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.

For the six months ended January 31, 2000, fund expenses were reduced by
$149,697 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 $844 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 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 six months ended January 31, 2000, Putnam Mutual Funds Corp.,
acting as underwriter received net commissions of $34,230 and $788 from
the sale of class A and class M shares, respectively, and received
$786,093 and $3,911 in contingent deferred sales charges from redemptions
of class B and C shares. A deferred sales charge of up to 1% is assessed
on certain redemptions of class A shares. For the six months ended January
31, 2000, Putnam Mutual Funds Corp., acting as underwriter received $7,824
on class A redemptions.

Note 3
Purchases and sales of securities

During the six months ended January 31, 2000, cost of purchases and
proceeds from sales of investment securities other than short-term
investments aggregated $83,108,221 and $238,847,754, respectively. There
were no purchases and sales of U.S. government obligations.
