Fund highlights

* "[T]here is one type of staid, secure bond fund that has been overlooked
   amid the global scramble for safety, and that is now emerging as the best
   bargain in the bond market: municipal-bond funds." 

                        -- The Wall Street Journal, October 5, 1998

* "Tax-free securities are in the midst of a renaissance.
   Higher-than-expected tax revenues, largely the result of a strong economy,
   and the healthy pace of credit upgrades at the state and city level are
   fostering greater confidence in the nation's municipal bond market."

Dear Shareholder:

Thanks in part to the rush of foreign investors to the safety of the U.S.
bond market, yields on long-term municipal bonds have moved remarkably
close to yields on taxable 30-year Treasury bonds. The increased demand
for tax-exempt bonds fed by this unusual environment has not been matched
by new supply; most issuers have already refinanced outstanding bonds at
lower rates and the flow of refundings has fallen off markedly. 

One of the greatest challenges for Putnam Tax Exempt Income Fund's
management has thus become that of finding securities that meet Putnam's
strict selection criteria. You will find details of this and other aspects
of the fund's fiscal 1998 performance in the following report.

I am pleased to introduce David E. Hamlin as your fund's new manager.
David was appointed just before the close of the fiscal year, joining
Putnam from the Vanguard Group, where he had been a principal since 1986.
He has 16 years of investment experience.

Respectfully yours, 

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
November 18, 1998



Report from the Fund Manager
David E. Hamlin

With so much uncertainty in the world's financial markets, municipal bonds
are providing a welcome retreat from the day-to-day volatility in stocks
and taxable bonds. Putnam Tax Exempt Income Fund's performance
demonstrates this relative safety, with class A shares delivering a total
return of 7.22% at net asset value (2.17% at public offering price) for
the 12 months ended September 30, 1998. The fund's focus on intermediate
bonds and its barbelled credit structure helped boost returns. Performance
for other shares and over longer periods is detailed beginning on page 8.

* MUNICIPAL MARKET OVERVIEW

Throughout the dramatic market shifts of August and September 1998, the
municipal market has stood its ground and even rallied slightly. Treasury
yields fell more dramatically than municipal bonds over the past 12
months, bringing yields on taxable and tax-free securities remarkably
close. On September 30, 1998, the yields on the Lehman Brothers Treasury
Bond Index and the Bond Buyer Municipal Bond Index were 5.08% and 5.04%,
respectively. Factoring in the tax advantages of municipal bonds, the
tax-free yield translates to an after-tax yield of 7.00%, assuming the top
39.6% federal income tax rate.

The unusual market volatility was set off by an unprecedented string of
international events: the unabated financial chaos in the Pacific Rim,
currency devaluations and defaults in Russia, and most recently, plunging
stock markets in Latin America. As foreign investors panicked about
plummeting stock markets, they began a flight to quality, selling hedge
funds and emerging-markets funds in favor of the safety of U.S. Treasury
bonds. This buying drove up the prices of Treasuries and pushed down their
yields. Since foreign investors do not benefit from the tax advantages of
municipal bonds, prices in this market did not rise as much as Treasuries.
However, municipal yields remain quite high relative to Treasuries, making
them an exceptional investment choice for U.S. investors.

In addition, the supply of municipal bonds has moderated. Normally, when
interest rates fall, refundings boost the bond supply. But rates have been
low for some time, most issuers have already completed their refundings,
and the supply of new issues has slowed down. In addition, with Treasury
rates close to municipal bond rates, refinancings have become less
attractive for municipalities.

* INTERMEDIATE FOCUS AND CREDIT BARBELL PROVE ADVANTAGEOUS

Throughout the year, we found the greatest value to be in the intermediate
part of the yield curve, that is, bonds with maturities ranging from 8 to
15 years. Intermediate bonds have benefited from the steepening yield
curve, which is the result of falling interest rates on short-term
securities. The Federal Reserve Board's recent adjustments to the federal
funds rate have pushed rates even lower. Over the period, intermediate
bonds offered more attractive income and greater price stability than
would have been obtained from a combination of shorter- and
longer-maturity bonds.

With regard to credit quality, the fund employed a barbell structure,
concentrating holdings at both the higher-quality and higher-yielding ends
of the municipal market. Our goal is to tap the volatility-dampening
effects of certain issues while simultaneously taking advantage of the
income potential of others. More than half of portfolio holdings are
securities of the highest credit quality (Aaa), while almost 21% of the
holdings are invested in bonds rated Baa, Ba, and B. This translates to an
average quality rating of Aa.

 unless noted otherwise; percentages may include unrated bonds considered
 by Putnam Management to be of comparable quality. Ratings will vary over
 time.


* SECTOR STRATEGY TAKES ADVANTAGE OF STRONG ECONOMY

Over the period, our emphasis on several key industry sectors contributed
to the fund's performance. The ongoing strength of the economy and weak
petroleum prices were boons for the transportation sector. Having priced
themselves effectively in their respective hub markets, airline-backed
industrial revenue bonds represented some of the best opportunities in the
lower-rated end of the municipal bond market. With increased passenger
capacity has come increased fees and cash flow from airport operations and
associated facilities such as restaurants, parking, hotels, and retail
outlets. The fund's current airline-related holdings involve carriers that
are diversified and operate outside the Pacific Rim.

At nearly 17% of total assets, health-care holdings performed well over
the period. Years of cost cutting, industry consolidation, and Medicare
reform are changing the landscape, and stringent credit research is
required to determine the likely winners. When evaluating performance
potential, the location, level, and quality of services offered by a
health-care facility are important. Abilene Health of Texas for Sears
Methodist Retirement with its attractive 5 7/8% coupon is a fund holding
that we believe will thrive in the future. While this holding, as well as
others discussed in this report, was viewed favorably during the period,
all holdings are subject to review in accordance with the fund's
investment strategy and may vary in the future.

State general obligation bonds (GOs) have also benefited from the stronger
economy. Many states around the nation have seen their credit ratings
improve as rising tax receipts, surplus state budgets, and favorable
credit fundamentals contributed to their fiscal health. In fact, just
after the close of the period, Moody's upgraded California GOs, and prices
rallied. We will be watching these and other GOs carefully to assess the
impact of a potential economic slowdown.

* OUTLOOK REMAINS CAUTIONARY

In this unusual bond market, the concern is more about what the equity
market will do than over what interest rates will do. We believe that the
bond market's positive performance depends upon stability in stocks and
global economies. New ground is being broken every day, and given the
uncertain environment, we have opted to maintain a conservative outlook. 

Our emphasis has been providing the best tax-free return while minimizing
downside performance if bond prices should fall. Consequently, we have
given up some income potential to help protect the value of the fund's
portfolio, and in turn, your share price. In such an environment, we don't
believe that our shareholders want to take on the risk that a higher
income bias would add. We reiterate our belief that this is not a good
time to invest in bonds with longer maturities and higher risk. Rather, we
currently expect to continue our emphasis on intermediate maturities (8 to
15 years) with solid yields, which offer more protection in a volatile
market.

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 9/30/98, there is no guarantee the fund will
continue to hold these securities in the future.

Past performance is no assurance of future results. 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. 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.

This performance information does not reflect any market volatility that
may have occurred since the date of the information. As a result, more
recent returns may be more or less than those shown.

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 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 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 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 does not take into account brokerage
commissions or other costs, may include bonds different from those in the
fund, and may pose different risks than the fund. 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.

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

  (a) Percentages indicated are based on net assets of 2,258,118,137.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to be the most recent ratings available at
      September 30, 1998 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 September 30, 1998. Securities
      rated by Putnam are indicated by "/P" and are not publicly rated. Ratings are not covered by the Report of
      independent accountants.

  (b) The aggregate identified cost on a tax basis is $2,046,192,178, resulting in gross unrealized appreciation and
      depreciation of $226,158,567 and $6,604,796, respectively, or net unrealized appreciation of $219,553,771.

(NON) Non income producing security.

Notes to financial statements
September 30, 1998 

Note 1
Significant accounting policies

Putnam Tax Exempt Income Fund (the "fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The fund seeks as high a level of current
income exempt from federal income tax as is consistent with preservation
of capital by investing primarily in a diversified portfolio of
longer-term tax exempt 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 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. The fair
value of restricted securities is determined by Putnam Investment
Management, Inc. ("Putnam Management") the fund's Manager, a wholly-owned
subsidiary of Putnam Investment, Inc., following procedures approved by
the Trustees, and such valuations and procedures are reviewed periodically
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). Interest income is recorded on the accrual basis.

Securities purchased or sold on a when-issued basis may be settled a month
or more after the trade date; interest income is accrued based on the
terms of the security. Losses may arise due to changes in the market value
of the underlying securities or if the counterparty does not perform under
the contract.

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.

Futures contracts are valued at the quoted daily settlement prices
established by the exchange on which they trade. Exchange traded options
are valued at the last sale price, or if no sales are reported, the last
bid price for purchased options and the last ask price for written
options. Options traded over-the-counter are valued using prices supplied
by dealers.

D) Line of credit The fund has entered into a committed line of credit
with certain banks. This line of credit agreement includes restrictions
that the fund maintain an asset coverage ratio of at least 300% and
borrowings must not exceed prospectus limitations. For the year ended
September 30, 1998 the fund had no borrowings against the line of credit.

E) Federal taxes It is the policy of the fund to distribute all of its
income within the prescribed time and otherwise comply with the provisions
of the Internal Revenue Code applicable to regulated investment companies.
It is also the intention of the fund to distribute an amount sufficient to
avoid imposition of any excise tax under Section 4982 of the Internal
Revenue Code of 1986, as amended. Therefore, no provision has been made
for federal taxes on income, capital gains or unrealized appreciation on
securities held nor for excise tax on income and capital gains.

F) Distributions to 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. These differences include temporary and
permanent differences of losses on wash sale transactions, dividends
payable, unrealized gains and losses on certain futures contracts and
straddle loss deferrals. 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 September 30, 1998, the fund reclassified $33,787 to increase
paid-in-capital, with an increase to accumulated net realized loss on
investments of $33,787. The calculation of net investment income per share
in the financial highlights table excludes these adjustments.

G) Amortization of bond premium and accretion of bond 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. 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: 0.60% of the first $500
million of average net assets, 0.50% of the next $500 million, 0.45% of
the next $500 million, 0.40% of the next $5 billion, 0.375% of the next $5
billion, 0.355% of the next $5 billion, 0.34% of the next $5 billion, and
0.33% thereafter.

As part of the subcustodian contract between the subcustodian bank and
Putnam Fiduciary Trust Company (PFTC), a subsidiary of Putnam Investments,
Inc., 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 September 30, 1998, 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 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 PFTC. Investor
servicing agent functions are provided by Putnam Investor Services, a
division of PFTC.

For the year ended September 30, 1998, fund expenses were reduced by
$296,863 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 $1,360
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 0.20%, 0.85%, and 0.50% of the average net assets
attributable to class A, class B, and class M shares respectively.

For the year ended September 30, 1998, Putnam Mutual Funds Corp., acting
as underwriter received net commissions of $123,040 and $1,951 from the
sale of class A and class M shares, respectively and $445,492 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 September 30, 1998, Putnam Mutual Funds
Corp., acting as underwriter received $12,061 on class A redemptions.
