Dear Shareholder:

Managing a portfolio of fixed-income securities has become increasingly
complex in recent years. The variety of available investments has proliferated
and U.S. investors are increasingly looking for opportunities beyond this
country's borders.

As a result, the managers of Putnam Federal Income Trust now find themselves
not only surveying interest rates and maturities, but concerning themselves
with such strategies as credit management, hedging non-U.S. currencies against
the dollar, and readjusting the weightings of various types of securities in
the fund's portfolio.

To help them with this process, fund managers Kenneth Taubes and Max Senter
are able to call on Putnam's extensive fixed-income research and analysis
capability. In the following report, Ken and Max discuss your fund's
performance during the first half of fiscal 1997 and look at prospects for the
second half.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
June 18, 1997



Report from the Fund Managers
Kenneth J. Taubes
Max S. Senter

The Federal Reserve Board's preemptive strike against inflation in late March
capped off a challenging semiannual period for shareholders of Putnam Federal
Income Trust. Over the six months ended April 30, 1997, bond investors reacted
- -- and, in some cases, overreacted -- to a flood of data that suggested the
economy was overheating. Their fears were far from unfounded: the economy grew
around a 5.6% annual rate in the first quarter of 1997, while unemployment
dropped to its lowest level since 1973. Fortunately, your fund steered a
successful course through the resulting market volatility, reaching the
midpoint of its 1997 fiscal year with a small but positive total return.
Complete performance information for the fund appears on pages 9 and 10.

* SECTOR POSITIONING PROVES EFFECTIVE

In its search for income, Putnam Federal Income Trust primarily invests in a
variety of high-quality bonds, including U.S. and foreign government bonds,
mortgage-backed investments, and bonds issued by creditworthy corporations.
The percentage of assets in each sector of these markets is adjusted in
response to our outlook for the economy and interest rates. This flexibility
proved invaluable during the first half of the fund's 1997 fiscal year. As
sectors rotated in and out of favor with investors, we successfully positioned
the portfolio to benefit from changing sentiments.

We began the period with a relatively heavy weighting in corporate bonds
(11.0% of portfolio holdings). Strong economic growth after years of
aggressive cost cutting had put many companies on solid financial footing. As
a result, 1996 was a banner year for corporate profits. According to one
survey in The Wall Street Journal, corporate profits gained a remarkable 61%
in the fourth quarter of 1996, compared with the fourth quarter of 1995. The
result of these gains, leading to credit-rating upgrades and higher bond
prices, was readily apparent in your fund's performance.

By February 1997, however, we were concerned that the situation was ripe for
correction. As a prelude to the federal funds rate increase in late March,
Federal Reserve Chairman Greenspan remarked to Congress that the current low
level of inflation at a time of sustained economic growth appeared to be
temporary, and more ominously, that "excessive optimism sows the seeds of its
own reversal." Fearing the impact of higher rates on the fund's corporate bond
holdings, we reduced the portfolio's position, eliminating first the
lower-credit-quality bonds we considered most sensitive to changes in interest
rates. Shortly thereafter, corporate bonds did suffer a downturn and we
believe our move helped protect the portfolio's value.

* INCREASE IN ALLOCATION TO MORTGAGE-BACKED SECURITIES CONTRIBUTES TO POSITIVE
  RESULTS

Another plus for performance was our decision to increase the fund's holdings
in mortgage-backed securities. We had concluded that their callability had
become less onerous at their higher yield levels. Furthermore, supply/demand
technical factors were, and remain, excellent. Finally, these securities were
available at attractive prices on a relative value basis and we did not
believe they would be too sensitive to any further increase in the federal
funds rate.

Footnote reads:
*These indexes reflect the general performance of market sectors in which the
 fund invests. The fund's performance will differ. Past performance is not
 indicative of future results. The indexes may include bonds different from
 those in the fund. It is not possible to invest directly in an index.

The fund typically holds a large number of mortgage-backed bonds in order to
benefit from their yield advantage over U.S. Treasuries (historically, a
difference of roughly one percentage point). These bonds carry higher yields
to compensate for their prepayment risk, which can dampen performance when
interest rates head lower.

Also beneficial to performance were the fund's holdings of so-called private
mortgages. Securitized by private lenders such as Chase Mortgage Finance Corp.
and Prudential Home Mortgage, these mortgages typically are too large (in
excess of about $210,000) to meet the standards of agencies such as the
Government National Mortgage Association (GNMA). The absence of a government
guarantee means private mortgages are somewhat less creditworthy than those
packaged by government agencies and therefore must pay more income to attract
investors. While these portfolio holdings, along with others discussed in this
report, were viewed favorably at the end of the fiscal period, all are subject
to review and adjustment in accordance with the fund's investment strategy and
may vary in the future.

Throughout the semiannual period, the U.S. dollar rose sharply against major
foreign currencies, eroding U.S. investors' returns on non-dollar-based
investments. For an investor in Italian government bonds, for example, a local
return of 1.45% became an almost 7% loss when translated into U.S. dollars,
according to J.P. Morgan. Because the fund began the period with a large
number of holdings hedged back to the dollar, the impact of the rising U.S.
currency was minimal. Furthermore, we reduced the international bond holdings
significantly, since we did not expect dramatic outperformance, especially
from European markets -- an opinion we still hold.

* SUBTLE SHIFT IN DURATION ADDS VALUE

As the period progressed, we became increasingly more cautious on the bond
market's prospects. In incremental adjustments, we gradually shifted the
portfolio's average duration from a relatively long position to a relatively
short one. The move proved well timed and added value to the fund's results.
By period's end, the move had resulted in a subtle shift from an essentially
neutral position to a mildly defensive one. An important tool for investment
professionals, duration measures a portfolio's sensitivity to changes in
interest rates and is expressed in years.

The shift was accomplished by lowering the portfolio's weighting in corporate
bonds and shifting the assets to mortgage-backed securities.

* "HISTORY COUNSELS CAUTION": ADVICE FOR BOND AND EQUITY INVESTORS

Federal Reserve Chairman Greenspan's call for prudence was directed at U.S.
equity investors but it may also be appropriate for those in the bond markets.
As this report was being written, the bond markets had recovered from their
late-March selloff, and a host of crucial economic reports suggested that
inflation was less of a threat than had earlier been predicted.

The Fed's decision to leave rates unchanged at its May meeting is no assurance
against future increases. In our view, in fact, the Fed's job is not finished,
and we believe it may find sufficient cause to raise rates again. We have
reached this conclusion because the U.S. economy's growth rate remains strong
and prospects of an upturn in foreign economies could lead the U.S. economy to
heat up further.

Going forward, therefore, we intend to keep the fund's duration neutral to
short, making the most of a flexible investment strategy by seeking income
where opportunities arise.

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 4/30/97, there is no guarantee the fund will continue to hold
these securities in the future.

Performance summary

Performance should always be considered in light of a fund's investment
strategy. Putnam Federal Income Trust is designed for investors seeking
high current income consistent with preservation of capital primarily
through U.S. government securities.

Performance data represent past results, do not reflect future
performance, and will differ for each share class. They do not take into
account any adjustment for taxes payable on reinvested distributions or,
for class A shares, distribution fees prior to implementation of the class
A distribution plan in 1990. 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. POP assumes 4.75% maximum sales charge for
class A shares and 3.25% for class M shares. CDSC for class B shares
assumes the applicable sales charge, with the maximum being 5%.

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 M shares have a lower initial sales 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 maximum 4.75% 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 shares and assumes redemption at the end of the
period. Your fund's 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.

COMPARATIVE BENCHMARKS

Lehman Brothers Government Bond Index* is an unmanaged list of publicly
issued U.S. Treasury obligations and debt obligations of U.S. government
agencies (excluding mortgage-backed securities). The average quality of
bonds included in the index may be higher than the average quality of
those bonds in which the fund customarily invests.

Lehman Brothers Corporate Bond Index* is an unmanaged list of publicly
issued, fixed-rate non-convertible investment-grade domestic corporate
debt securities frequently used as a general measure of the performance of
fixed-income securities.

Lehman Brothers Long-Term Treasury Bond Index* is composed of all bonds
covered by the Lehman Brothers Treasury Bond Index with maturities of 10
years of greater.

Lehman Brothers Mortgage-Backed Securities Index* is an unmanaged list of
GNMA bonds.

Salomon Brothers World Government Bond Index* is a market-capitalization
weighted benchmark that tracks the performance of government-bond markets
in 14 countries.

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

*Securities indexes assume reinvestment of all distributions and interest
 payments and do not take in account brokerage fees or taxes. Securities in
 the fund do not match those in the indexes and performance of the fund
 will differ. It is not possible to invest directly in an index.

Notes to financial statements
April 30, 1997 (Unaudited)

Note 1
Significant accounting policies

Putnam Federal Income Trust (the "fund") is registered under the Investment
Company Act of 1940, as amended, as a diversified, open-end management
investment company. The fund seeks high current income, consistent with
preservation of capital, through investments primarily in U.S. government
securities.

The fund offers class A, class B 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 M shares are sold with a maximum
front-end sales charge of 3.25% and pay an ongoing distribution fee that is
lower than class B shares and higher than class A 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 Investments for which market quotations are readily
available are stated at market value, which is determined using the last
reported sale price, or, if no sales are reported -- as in the case of some
securities traded over-the-counter -- the last reported bid price. Securities
quoted in foreign currencies are translated into U.S. dollars at the current
exchange rate. Short-term investments having remaining maturities of 60 days
or less are stated at amortized cost, which approximates market value, and
other investments, are stated at fair value following procedures approved by
the Trustees. Market quotations are not considered to be readily available for
long-term corporate bonds and notes; such investments are stated at fair value
on the basis of valuations furnished by a pricing service, approved by the
Trustees, which determines valuations for normal, institutional-size trading
units of such securities using methods based on market transactions for
comparable securities and various relationships between securities which are
generally recognized by institutional traders.

B) Joint trading account Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the fund may transfer uninvested cash
balances into a joint trading account along with the cash of other registered
investment companies and certain other accounts managed by Putnam Investment
Management, Inc. ("Putnam Management"), the fund's Manager, a wholly-owned
subsidiary of Putnam Investments, Inc.. These balances may be invested in one
or more repurchase agreements and/or short-term money market instruments.

C) Repurchase agreements The fund, or any joint trading account, through its
custodian, receives delivery of the underlying securities, the market value of
which at the time of purchase is required to be in an amount at least equal to
the resale price, including accrued interest. Putnam Management is responsible
for determining that the value of these underlying securities is at all times
at least equal to the resale price, including accrued interest.

D) 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.

E) Foreign currency translation The accounting records of the fund are
maintained in U.S. dollars. The market value of foreign securities, currency
holdings, other assets and liabilities are recorded in the books and records
of the fund after translation to U.S. dollars based on the exchange rates on
that day. The cost of each security is determined using historical exchange
rates. Income and withholding taxes are translated at prevailing exchange
rates when accrued or incurred. The fund does not isolate that portion of
realized or unrealized gains or losses resulting from changes in the foreign
exchange rate on investments from fluctuations arising from changes in the
market prices of the securities. Such fluctuations are included with the net
realized and unrealized gain or loss on investments. Net realized gains and
losses on foreign currency transactions represent net exchange gains or losses
on closed forward currency contracts, disposition of foreign currencies and
the difference between the amount of investment income and foreign withholding
taxes recorded on the fund's books and the U.S. dollar equivalent amounts
actually received or paid. Net unrealized gains and losses on foreign currency
transactions arise from changes in the value of open forward currency
contracts and assets and liabilities other than investments at the period end,
resulting from changes in the exchange rate.

F) Forward currency contracts The fund may engage in forward currency
contracts, which are agreements between two parties to buy and sell currencies
at a set price on a future date, to protect against a decline in value
relative to the U.S. dollar of the currencies in which its portfolio
securities are denominated or quoted (or an increase in the value of a
currency in which securities a fund intends to buy are denominated, when a
fund holds cash reserves and short-term investments). The U.S. dollar value of
forward currency contracts is determined using forward currency exchange rates
supplied by a quotation service. The market value of the contract will
fluctuate with changes in currency exchange rates. The contract is "marked to
market" daily and the change in market value is recorded as an unrealized gain
or loss. 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 fund could be exposed to
risk if the value of the currency changes unfavorably, if the counterparties
to the contracts are unable to meet the terms of their contracts or if the
fund is unable to enter into a closing position.

G) 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.

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.

H) TBA purchase commitments The fund may enter into "TBA" (to be announced)
purchase commitments to purchase securities for a fixed unit price at a future
date beyond customary settlement time. Although the unit price has been
established, the principal value has not been finalized. However, the amount
of the commitments will not fluctuate more than 1.0% from the principal
amount. The fund holds, and maintains until settlement date, cash or
high-grade debt obligations in an amount sufficient to meet the purchase
price, or the fund may enter into offsetting contracts for the forward sale of
other securities it owns. Income on the securities will not be earned until
settlement date. TBA purchase commitments may be considered securities in
themselves, and involve a risk of loss if the value of the security to be
purchased declines prior to the settlement date, which risk is in addition to
the risk of decline in the value of the fund's other assets. Unsettled TBA
purchase commitments are valued at the current market value of the underlying
securities, according to the procedures described under "Security valuation"
above.

Although the fund will generally enter into TBA purchase commitments with the
intention of acquiring securities for their portfolio or for delivery pursuant
to options contracts it has entered into, the fund may dispose of a commitment
prior to settlement if Putnam Management deems it appropriate to do so.

I) TBA sale commitments The fund may enter into TBA sale commitments to hedge
its portfolio positions or to sell mortgage-backed securities it owns under
delayed delivery arrangements. Proceeds of TBA sale commitments are not
received until the contractual settlement date. During the time a TBA sale
commitment is outstanding, equivalent deliverable securities, or an offsetting
TBA purchase commitment deliverable on or before the sale commitment date, are
held as "cover" for the transaction.

Unsettled TBA sale commitments are valued at the current market value of the
underlying securities, generally according to the procedures described under
"Security valuation" above. The contract is "marked-to-market" daily and the
change in market value is recorded by a fund as an unrealized gain or loss. If
the TBA sale commitment is closed through the acquisition of an offsetting
purchase commitment, the fund realizes a gain or loss on the underlying
security. If the fund delivers securities under the commitment, the fund
realizes a gain or a loss from the sale of the securities based upon the unit
price established at the date the commitment was entered into.

J) 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 October 31, 1996, the fund had a capital loss carryover of approximately
$187,373,000 available to offset future capital gains, if any. The amount of
the carryover and the expiration dates are:

Loss Carryover                        Expiration
- ---------------------------------------------------
$118,265,000                       October 31, 1997

  15,005,000                       October 31, 1998

  54,103,000                       October 31, 2002

K) Distributions to shareholders Distributions to shareholders are recorded by
the fund on the ex-dividend date. At certain times, the fund may pay
distributions at a level rate even though, as a result of market conditions or
investment decisions, the fund may not achieve projected investment results
for a given period. 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.

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: 0.75% of the first $100 million of
average net assets, 0.65% of the next $100 million, 0.55% of the next $300
million, 0.45% of the next $500 million, and 0.40% of any amount over $1
billion.

As part of the custodian 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 April 30, 1997, the payable to the subcustodian bank represents the amount
due for cash advance for the settlement of a security purchased.

The fund reimburses Putnam Management 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 wholly-owned subsidiary of Putnam Investments, Inc.
Investor servicing agent functions are provided by Putnam Investor Services, a
division of PFTC.

For the six months ended April 30, 1997, fund expenses were reduced by $89,475
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 these assets utilized in connection with the
expense offset arrangements in an income producing asset if it had not entered
into such arrangements.

Trustees of the fund receive an annual Trustees fee of $750 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 "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 in the fund and are invested
in the fund or in other Putnam funds until distribution in accordance with the
Plan.

The fund has adopted an unfunded noncontributory defined benefit pension plan
covering all Trustees of the Fund who have served as Trustee for at least five
years. Benefits under the plan are equal to 50% of the Trustee's average total
retainer and meeting fees for the three years preceding retirement. Pension
expense for the fund is included in Trustee fees 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 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% and 1.00% of the average net assets
attributable to class A, class B and class M shares, respectively. The
Trustees have approved payment by the fund at an annual rate of 0.25%, 1.00%
and 0.50% of the average net assets attributable to class A, class B and class
M shares respectively.

For the six months ended April 30, 1997, Putnam Mutual Funds Corp., acting as
underwriter received net commissions of $27,899 and $178 from the sale of
class A and class M shares, respectively and received $16,759 in contingent
deferred sales charges from redemptions of class B shares. A deferred sales
charge of up to 1% is assessed on certain redemptions of class A shares. For
the six months ended April 30, 1997, 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 April 30, 1997, purchases and sales of investment
securities other than U.S. government obligations and short-term investments
aggregated $87,515,297 and $112,783,528, respectively. Purchases and sales of
U.S. government obligations aggregated $377,628,638 and $367,043,391,
respectively. In determining the net gain or loss on securities sold, the cost
of securities has been determined on the identified cost basis.

Note 4
Capital shares

At April 30, 1997, there was an unlimited number of shares of beneficial
interest authorized. Transactions in capital shares were as follows:
