Dear Shareholder:

Astute portfolio maneuvers, coupled with well-timed defensive strategies,
helped Putnam Federal Income Trust deliver a competitive total return during
the fiscal year that ended on October 31, 1997. To achieve this positive
result, fund managers Kenneth Taubes and Max Senter skillfully adjusted both
the portfolio's average duration and its mix of securities throughout the year
in response to a continuing stream of changing conditions.

Nevertheless, an underlying current of nervousness prevailed throughout the
period as both the Federal Reserve Board and investors kept a close watch on
inflation, fearing that the still robust economy might ignite it at any
moment. The Fed's preemptive thrust in March with a quarter-point increase in
short-term interest rates seemed to do the trick without extinguishing the
economy's long-standing growth cycle.

Plenty of challenges remain as your fund embarks on a new fiscal year. In the
following report, Ken and Max discuss performance in the year just ended and
take a look at prospects for the months ahead.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
December 17, 1997



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

Considering the winter bear market, the summer rally, and the turmoil in
emerging markets this fall, Putnam Federal Income Trust's 1997 fiscal year was
anything but dull. Although fixed-income investors had their share of ups and
downs, your fund's flexible investment strategy enabled it to complete the
12-month period ended October 31, 1997, with an 8.41% class A share return at
net asset value. At public offering price, class A shares returned 3.25%. For
more performance information, including the results for other share classes,
please see pages 8, 9, and 10.

* INVESTORS ADJUST TO GROWTH WITHOUT INFLATION

Economic activity in the first half of the fund's fiscal year was vigorous and
widespread. Consumer spending rose, unemployment fell, sales of new homes set
records, and manufacturing capacity became increasingly strained. Anticipating
a potential spike in inflation, the Federal Reserve Board raised short-term
interest rates by a quarter of a percentage point in late March. Bonds and
bond funds most sensitive to changing interest rates suffered the greatest
price declines, but returns among fixed-income investments in general were
lackluster over the first half of the fiscal year. Having become more cautious
about the bond market's prospects, we gradually reduced the portfolio's
sensitivity to changes in interest rates by shortening its duration. The move
proved well timed and boosted the fund's performance in the first half.

The fiscal year's second half brought a decidedly more upbeat mood to the
market. Economic activity tapered off in a manner that persuaded the Fed to
leave interest rates unchanged. Despite a continued strong employment picture,
retail sales declined and manufacturers slowed production. Although the
country's gross domestic product (GDP) measured growth at more than 4% in the
first six months of the period (4.9% in the first quarter of 1997), growth in
the second half remained much closer to 3%. By June, as reports of moderating
economic growth mounted, many market watchers had ruled out any further 1997
rate increases. This new landscape proved a welcome change for fixed-income
investors: bond prices rose throughout the spring and summer and yields fell.
Although encouraged, we remained cautious about lengthening portfolio duration
too much during this period -- and, consequently, increasing the fund's
interest-rate exposure -- suspecting that the Fed's concern over unsustainably
high economic growth might eventually prompt additional tightening of
short-term interest rates. Instead, we chose to focus on altering the fund's
mix of investments, including applying greater resources to the
mortgage-backed segment of the fixed-income market.

* MORTGAGES FAVORED THROUGHOUT YEAR

In its search for income, your fund invests in a variety of high-quality
bonds, including U.S. and foreign government bonds, mortgage-backed
securities, and bonds issued by creditworthy corporations. Because these
investments vary in their sensitivity to interest rates and changes in the
economy, the percentage of assets in each sector is adjusted regularly to
reflect our outlook.

For example, throughout the first half of the fiscal year, we considered that
mortgage-backed securities provided a distinct advantage over U.S. Treasuries
of comparable maturity and therefore weighted them heavily in the portfolio.
As we began the fiscal year, mortgages constituted 45% of net assets; this
level rose to 58.8% this past spring and stayed constant through the end of
October. Mortgage-backed securities generally offer higher yields than
Treasuries in order to compensate investors for the risk of prepayment.
However, prepayment risk was not an issue for a large part of the year, since
economic growth was generally strong and interest rates appeared more likely
to rise than fall. Only during the summer did Treasuries gain the upper hand.
Their sensitivity to changing interest rates translated into relatively
greater price appreciation as the market rallied and rates moved lower.

*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.

* FOREIGN AND CORPORATE BOND HOLDINGS REDUCED

To finance the additional investment in mortgage-backed securities, we scaled
back the fund's corporate and foreign bond holdings, having begun the period
with a relatively heavy weighting in corporate bonds. Corporate profits had a
banner year in 1996 and the subsequent credit-rating upgrades and higher bond
prices benefited your fund's performance.

By early 1997, however, we believed that the seeds of higher interest rates
had been sown and that an increase in rates would dampen performance of the
fund's corporate bond holdings. We first eliminated the lower-credit-quality
bonds we considered most sensitive to changes in interest rates. The move
proved timely, as higher-yielding corporate bonds did suffer a downturn
shortly thereafter.

Later in the year, as events in Southeast Asia were heating up, high-grade
corporate bonds suffered a setback on the grounds that weaker currencies in
Asian export countries would cut into U.S. corporate profits.

Throughout the first half of fiscal 1997, the U.S. dollar rose sharply against
major foreign currencies, eroding U.S. investors' returns on nondollar-based
investments. We reduced the fund's foreign holdings dramatically in early
1997, concluding that domestic bonds were more likely to outperform their
foreign counterparts, particularly in European markets.

*CAUTION PREVAILS FOR COMING MONTHS

Whether the Fed will raise rates in the coming year remains an important
question for fixed-income investors. Unemployment remains low and industrial
capacity tight. Consumer spending, which had lagged income growth in the first
half of the year, posted sharp increases in the third quarter as measured by
rising retail sales. Stronger foreign economies, particularly in Europe, have
fueled U.S. export growth of late. The U.S. economy has registered four
calendar quarters of GDP growth above 3%, and yet the Fed maintains that
noninflationary growth is something more on the order of 2.5%. In light of
these factors and considering that the summer's bond market rally may have
been overdone, we currently intend to keep the fund's slightly defensive
duration stance in the coming months, making the most of a flexible investment
strategy by seeking income wherever 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 10/31/97, there is no guarantee the fund will continue to hold
these securities in the future.

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 (where available) 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 B and class M shares for periods prior
to their inception are derived from the historical performance of class A
shares, adjusted to reflect both the initial sales charge or CDSC, if any,
currently applicable to each class and, in the case of class B and class M
shares, the higher operating expenses applicable to such shares. All
returns assume reinvestment of distributions at NAV and represent past
performance; they do not guarantee future 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.

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 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 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.

Notes to financial statements
October 31, 1997

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. Discount on
original issue bonds are accreted according to the yield-to-maturity 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 gains and losses 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 appreciation and
depreciation of assets and liabilities in foreign currencies 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 current 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. 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.

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 the 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. 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, 1997, the fund had a capital loss carryover of approximately
$69,108,000 available to offset future capital gains, if any. The amount of
the carryover and the expiration dates are:

 Loss Carryover       Expiration
- ----------------   ----------------
    $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. These differences
include treatment of realized and unrealized gains and losses on forward
foreign currency contracts, currency gains and losses on foreign bonds, losses
on wash sale transactions, expiration of a capital loss carryover, market
discount and paydown gains and losses on mortgage-backed securities.
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 October 31, 1997, the fund
reclassified $242,739 to increase undistributed net investment income and
$117,126,116 to decrease paid-in-capital, with a decrease in accumulated net
realized loss on investments of $116,883,377. The calculation of net
investment income per share in the financial highlights table excludes these
adjustments.

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.

The fund reimburses Putnam Management an allocated amount for the compensation
and related expenses of certain officers of the fund and their staff who
provide administrative services to the fund. The aggregate amount of all such
reimbursements is determined annually by the Trustees.

Custodial functions for the fund's assets are provided by Putnam Fiduciary
Trust Company (PFTC), a subsidiary of Putnam Investments, Inc. Investor
servicing agent functions are provided by Putnam Investor Services, a division
of PFTC.

For the year ended October 31, 1997, fund expenses were reduced by $220,936
under expense offset arrangements with PFTC and brokerage service
arrangements. Investor servicing and custodian fees reported in the Statement
of operations exclude these credits. The fund could have invested a portion of
the assets utilized in connection with the expense offset arrangements in an
income producing asset if it had not entered into such arrangements.

Trustees of the funds receive an annual Trustees fee of which $704 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 in the fund and are
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 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 currently limit payment by the fund to 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 year ended October 31, 1997, Putnam Mutual Funds Corp., acting as
underwriter received net commissions of $47,015 and $367 from the sale of
class A and class M shares, respectively and $22,542 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 year
ended October 31, 1997, Putnam Mutual Funds Corp., acting as underwriter
received no monies on class A redemptions.

Note 3
Purchases and sales of securities

During the year ended October 31, 1997, purchases and sales of investment
securities other than U.S. government obligations and short-term investments
aggregated $197,006,617 and $218,561,696, respectively. Purchases and sales of
U.S. government obligations aggregated $598,736,801 and $593,427,707,
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 October 31, 1997, there was an unlimited number of shares of beneficial
interest authorized. Transactions in capital shares were as follows:
