Dear Shareholder:

It is a pleasure to greet you in our new roles as Chairman of the
Trustees and President of the Funds. As you know, both of us have been
members of the Board of Trustees for a number of years -- years during
which the global securities markets, the mutual fund industry, and
Putnam itself have experienced tremendous growth and change.

As we look to the future, we are certain that the changes will be
breathtaking in their scope. What will not change is the Trustees'
dedication to serving the best interests of our shareholders.

We welcome the challenges that lie ahead and are confident that Putnam
and your Board will continue to face those challenges successfully as
they have for more than 60 years. We look forward to helping you meet
your financial objectives for many years to come.

Respectfully yours,

/S/ JOHN A. HILL                   /S/ GEORGE PUTNAM, III

REPORT FROM FUND MANAGEMENT

David E. Hamlin

After months of positioning your fund for an eventual turnaround in the
fixed-income markets, we are pleased to report that this happy state of
events has come to pass. During the second half of Putnam Tax Exempt
Income Fund's fiscal year, municipal bond markets rallied as investors
sought the relative calm of fixed-income securities and the greater
diversification they afford following this spring's dramatic stock
market correction. With the increased demand for municipal securities
have come higher bond prices.

* MUNICIPAL BONDS RALLY IN SPITE OF ONGOING INFLATION CONCERNS

This year investors have been reminded of one of the basic principles of
investing: When the financial markets turn around, they move so fast
that investors who are not already positioned in the recovering sector
are often too late to take advantage of the upswing. When the Nasdaq
plunged in March, setting off a long string of declines in other equity
markets, bonds were suddenly the place to be. Even as the Federal
Reserve Board was absorbed in its agenda of raising interest rates, the
municipal bond market began anticipating the beginning of a slowdown in
the economy and better performance.

Over the past six months, we have begun to see positive total returns as
increased investor demand drove up bond prices and interest rates in the
municipal market began to fall. The AAA sector of the municipal market
has benefited the most. Since AAA bonds represent the highest quality
and most liquid area of the municipal market, the most substantial
increase in demand -- along with the greatest price increase and rate
declines -- occurred in this sector. On September 30, 2000, your fund
held 54% of its total assets in AAA-rated or insured municipal bonds.

* FLIGHT TO QUALITY SPARKS WIDER CREDIT SPREADS

When a market has fallen out of favor, lower-credit quality securities
are often the first to be sold, and investors certainly favored equities
over bonds for much of the period. However, as demand for the
highest-quality municipal bonds increased during the period, the prices
of lower-rated bonds lagged behind, widening the credit spread between
higher-quality and lower-rated bonds. In the past, we have stated that
it has been our strategy to increase lower-rated holdings in many of our
tax-exempt portfolios. We still believe this is a valid strategy
because, in our opinion, the lag in lower-rated bond prices does not
indicate rising defaults or a looming recession but simply reflects
earlier changes in investor sentiment and resulting cash flows out of
municipal bond funds.

By increasing holdings in lower-rated sectors, the fund is buying future
appreciation potential at today's lower prices and will be earning high
interest rates while waiting for an improvement in performance. We
continue to believe that as long as lower-rated credit investments are
used in a broadly diversified manner across sectors and states,
investors will be rewarded for their patience.

Our analysts sift through many municipal bond issues, but not all of
these securities meet our investment criteria. Today we think the
health-care sector offers some of the most attractive opportunities for
income and credit upgrades. Since the advent of the Balanced Budget Act
and its mandate for lower Medicare reimbursements in 1996, the
health-care industry has experienced massive restructurings and
cost-cutting programs. While the widening of credit spreads has been
most dramatic for hospitals, our outlook for this sector is improving
since Congress recently increased Medicare reimbursements.


"In a flat to down year for stocks, it's the bond investors who've got
bragging rights."

 -- Special to TheStreet.com, September 22, 2000


We took advantage of lower prices late this summer to purchase both
Louisiana Public Facility hospital revenue bonds for Lake Charles
Memorial Hospital and Colorado Springs Hospital bonds. We also added to
the fund's position in bonds issued by Oklahoma Health Care Facilities
for Hill Crest Healthcare Systems. While these holdings, along with
others discussed in this report, were viewed favorably at the end of the
period, all are subject to review and adjustment in accordance with the
fund's investment strategy and may vary in the future.

Elsewhere in the health-care sector, we purchased bonds issued by North
Carolina Medical Care Retirement Facility for United Methodist
Retirement Home, which is located in the Raleigh-Durham area. This
facility's proven management and close  proximity to Duke University
make it an attractive destination for retirees. Furthermore, North
Carolina is a high-tax state with strong demand for tax-free securities.

In our continuing effort to diversify portfolio holdings by location and
industry, we also bought municipal bonds financing land development in
Florida, where changing demographics and a strong economy are creating a
strong demand for additional housing. The Oakstead Community Development
District bonds are financing various infrastructure improvements such as
the  construction of roads and water and sewer lines.

* YIELD CURVE CHANGES PROMPTED SHIFTS IN MATURITIES BUT DURATION
  REMAINED STABLE

The fund ended its fiscal year slightly less than its duration 12 months
earlier. (Duration is a measure of the portfolio's maturity structure
and reflects the price sensitivity of holdings to changes in interest
rates.) While it would appear that little had happened during the course
of the year, nothing could be further from the truth. In fact, market
conditions have been in constant flux, and we have been on our toes
steadily monitoring the day-to-day trends in the municipal bond market.

The changing shape of the yield curve helps tell the story. We started
the year with a modestly steep yield curve, but it had steepened further
by the end of 1999, when fears about the Y2K issue and higher interest
rates in response to a booming economy created great uncertainty. At
that time, we were buying longer-maturity bonds at especially attractive
prices and selling shorter-maturity bonds on our belief that heightened
concerns were unfounded.

As the new year dawned and investors realized that the Y2K fears were
overblown, interest rates fell. The yield curve flattened in response to
a more bullish sentiment. Consequently, we found more opportunities in
intermediate maturities. Following the stock market's spring correction,
which had a dampening effect on interest rates, the yield curve
continued to flatten until summer, when it again reversed course. The
yield curve steepened through September, providing another opportunity
to sell intermediate-maturity bonds at a profit.

The Fed did not raise interest rates in October, and the odds are good
that it will move to a neutral bias if the equity markets remain
volatile. As the negative cash flow out of municipal bond funds begins
to lessen, a consequence of improving performance, the investments in
your fund, especially the lower-rated bonds, are well positioned to reap
the benefits of a market that not only has turned around but has
outperformed many equity indexes so far this year.

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 9/30/00, there is no guarantee the
fund will continue to hold these securities in the future.

*Index inception date was 12/31/79.

Past performance is no assurance of future results. More recent returns
may be 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-, 5- and 10-year,
if 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. For class C
shares, returns for periods prior to their inception are derived from
the historical performance of class A 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 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 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, preceded by the Report of independent
accountants, 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.


REPORT OF INDEPENDENT ACCOUNTANTS

The Board of Trustees and Shareholders
Putnam Tax Exempt Income Fund

We have audited the accompanying statement of assets and liabilities of
Putnam Tax Exempt Income Fund, including the fund's portfolio, as of
September 30, 2000, the related statement of operations for the year
then ended, statements of changes in net assets for each of the years in
the two-year period then ended and financial highlights for each of the
years or periods in the two-year period then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits. The
financial highlights for each of the years in the three-year period ended
September 30, 1998 were audited by other auditors whose report dated
November 10, 1998 expressed an unqualified opinion on those financial
highlights.

We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that
we plan and perform our audit to obtain reasonable assurance about
whether the financial statements and financial highlights are free of
material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as
of September 30, 2000 by correspondence with the custodian and brokers.

An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the
financial position of as of September 30, 2000, the results of its
operations, changes in its net assets and financial highlights for each
of the years or periods described above, in conformity with accounting
principles generally accepted in the United States of America.

  (a) Percentages indicated are based on net assets of $1,772,705,287.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to
      be the most recent ratings available at September 30, 2000 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, 2000. 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 $1,717,904,433,
      resulting in gross unrealized appreciation and depreciation of
      $86,944,332 and $45,909,172, respectively, or net unrealized
      appreciation of $41,035,160.

(STP) The interest rate and date shown parenthetically represent the new
      interest rate to be paid and the date the fund will begin receiving

      total market value of restricted securities held at September 30, 2000
      was $144,669,830 or 8.2% of net assets.

(SEG) A portion of these securities was pledged and segregated with the
      custodian to cover margin requirements for futures contracts at
      September 30, 2000.

      144A after the name of a security represents those exempt from
      registration under Rule 144A of the Securities Act of 1933. These
      securities may be resold in transactions exempt from registration,
      normally to qualified institutional buyers.

      The rates shown on IFB are securities paying interest rates that
      vary inversely to changes in the market interest rates, and VRDN's are
      the current interest rates at September 30, 2000.

NOTES TO FINANCIAL STATEMENTS
September 30, 2000

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, 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 and class C 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 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.
Restricted securities are stated at fair value following procedures
approved by the Trustees. 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). 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 year ended
September 30, 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 or
unrealized appreciation on securities held nor for excise tax on income
and capital gains. At September 30, 2000, the fund had a capital loss
carryover of approximately $14,731,000 available to offset future net
capital gain, if any, which will expire on September 30, 2008.

F) Distributions to shareholders Distributions to shareholders from net
investment income are recorded by the fund on the ex-dividend date.
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 sales transactions, post-October loss
deferrals, dividends payable, defaulted bond interest, unrealized gains
and losses on certain futures contracts, market discount, straddle loss
deferrals, book accretion/amortization adjustment and partnership
income. 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, 2000, the fund reclassified $558,943 to decrease
distribution in excess of net investment income and $1,662,314 to
decrease paid-in-capital, with a decrease to accumulated net realized
losses of $1,103,371. 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 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, stepped-coupon bonds and payment
in kind 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 upon the lesser of (i) an annual rate of
0.50% of the average net asset value of the Fund or (ii) 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, 0.33% 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.

Under 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, 2000, the payable to the
subcustodian bank represents the amount due for cash advance for the
settlement of a security purchased.

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, 2000, fund expenses were reduced by
$344,168 under expense offset arrangements with PFTC and brokerage
service arrangements (only if applicable to your fund). 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 $1,474
has been allocated to the fund, and an additional fee for each Trustees
meeting attended. 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 a 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 Retail Management, Inc., 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 Retail Management, Inc. 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%, 0.85%,
1.00% and 0.50% of the average net assets attributable to class A, class
B, class C and class M shares respectively.

For the year ended September 30, 2000, Putnam Retail Management, Inc.,
acting as underwriter received net commissions of $59,359 and $810 from
the sale of class A and class M shares, respectively, and received
$309,982 and $1,920 in contingent deferred sales charges from
redemptions of class B and class C shares, respectively. A deferred
sales charge of up to 1% is assessed on certain redemptions of class A
shares. For the year ended September 30, 2000, Putnam Retail Management,
Inc., acting as underwriter received $30,182 on class A redemptions.
