Dear Shareholder:

This is the last letter to you and the other shareholders of Putnam
Pennsylvania Tax Exempt Income Fund that I will be signing. After more
than 30 years as Chairman of the Trustees and President of the Putnam
Funds, the time has come for me to step aside.

In June, John Hill will become Chairman. John is currently an independent
Trustee and has served on the board for the past 14 years. In addition, my
son, George Putnam, III, will take on the role of President. I am
confident that the leadership of the funds will be in exceptionally strong
hands.

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

In one final piece of news, I am pleased to announce the appointment of
Susan A. McCormack as your fund's manager. Before joining Putnam as a
tax-exempt bond analyst in 1994, Susan was with Merrill Lynch. She has 13
years of investment experience.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees

Report from the Fund Manager

Susan A. McCormack

Fixed-income investors had a tough time making money in 1999. A strong
U.S. economy and tight labor markets prompted the Federal Reserve Board to
raise interest rates on three occasions, which made the yields on existing
bonds less attractive. Although bond prices suffered and Putnam
Pennsylvania Tax Exempt Income Fund's returns for the six months ended
November 30 reflect this unfavorable environment, we took advantage of
opportunities to boost the fund's yield and position the portfolio for the
next turn in the market. The fund's 30-day SEC yield for class A shares at
NAV increased more than a full percentage point during the period to 4.96%
on November 30, 1999, equivalent to an 8.45% after-tax yield for investors
in Pennsylvania's top tax bracket.

* FUND'S CONSERVATIVE APPROACH HELPS

Your fund's chief investment objective is tax-free income. Where possible,
we also try to achieve the best total return with the least amount of
risk. This conservative approach means we are more likely to outperform in
a down market than to be industry leaders in an up market. Although
performance for this period was negative, the fund's makeup at the start
of the period enabled us to avoid greater losses.

*Based on net assets as of 11/30/99. Holdings will vary over time.


We began the fiscal year with a healthy amount of money invested in
short-term bonds, those maturing in less than five years. All bonds share
an inverse relationship with interest rates -- that is, their prices tend
to decline as rates rise -- but short-term instruments are generally less
sensitive to rate increases than longer-term bonds. Our roughly 20%
weighting in these short-term investments provided a buffer against some
of the market's selloff. The fund's modest holdings of higher-yielding,
lower-rated bonds also helped. From a credit standpoint, bonds rated below
investment grade are riskier investments. However, when interest rates are
rising these lower-rated bonds tend to be relatively stable as long as
investors are earning premium yields.

* STRATEGY FOCUSED ON HIGHER YIELDS

After nine consecutive years of economic growth, most states in the Union
are running fiscal surpluses, and Pennsylvania is no exception. With tax
revenues high, municipalities have fewer reasons to take on additional
debt, so new bond issuance is down sharply. The dearth of new issues this
year has prompted money managers to look for opportunity in the secondary
market, and the selloff provided plenty of it.

As the period progressed, we pared back our short-term holdings and bought
long-term bonds on weakness. The transfer of assets from short- to
long-term investments helped the fund in two ways. First, we were able to
increase the fund's yield more than a full percentage point without
increasing our exposure to credit risk. Second, by adding bonds with
greater sensitivity to interest rates, we believe the fund is better
positioned for a positive turn in the market.

 will vary over time.


Within the municipal market, we also found opportunity in weaker sectors,
including the hospital sector. Hospitals continue to suffer from the
Balanced Budget Act of 1996, which set reimbursement limits for Medicare
patients regardless of cost and effectively capped hospital income.
Hospitals have also been the victims of poor management, acquiring
physician practices and HMOs, for example, that eventually lost far more
money than they earned. Although many hospital issues remained downtrodden
throughout the period, some have begun to shape up. With our staff of
seasoned analysts, we believe we have the ability to pick and choose
successfully in this distressed sector. One opportunity we took advantage
of during the period was a bond for Bloomsberg Hospital, offering a 6%
yield on a depressed price. While this holding and 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.


For the 12 months ended December 31, 1999, the fund's class A share return
ranked in the top third of its peers (20 out of 60 Pennsylvania tax-free
funds), according to Lipper.

Lipper is an industry research firm, whose rankings are based on total return
performance, vary overtime, and do not reflect the effects of sales charges.
The fund's class A shares ranked 20 out of 60 (33rd percentile), 32 out of 50
(63rd percentile), and 4 out of 12 (31st percentile) for l- 5- and 10-year
performance, respectively, as of 12/31/99. Performance of other share classes
will vary. Past performance is not indicative of future results.


Thousands of projects, just two types of bonds

Although municipal bonds are used to finance thousands of different public
projects, from highways to water treatment plants, there are only two basic
types of bonds. The difference is in how each type repays its investors. With
general obligation bonds (GOs), investors receive their interest and principal
from property taxes. The bonds are secured by the ability of the municipality
to raise taxes. Cities and towns usually issue general obligation bonds to
finance schools, parks, or public building projects. Revenue bonds, on the
other hand, are repaid through fees derived from tolls, charges, or rents.
Highways, bridges, and water and sewage treatment plants are typical projects
financed or improved by revenue bond proceeds. Industrial revenue bonds
operate under the same principle but are used to finance projects for
corporations and other private users in cases where a state or local
government thinks the project is good for the community.


Outside the hospital sector, the pickings were slimmer. Our purchases
included two Philadelphia school district bonds bought with the proceeds
from sales of Puerto Rico bonds. Occasionally, we look to Puerto Rico as a
source of portfolio diversification because municipal bonds issued by the
commonwealth offer tax-free yields to U.S. residents. As state issuance
has dropped around the Continental United States, investors have bid up
the prices of Puerto Rico municipal bonds despite a generally higher
degree of credit risk. We sold several Puerto Rico holdings at a premium
during the period, including Puerto Rico Electric and Puerto Rico Highway,
and these sales reduced the fund's overall stake in the island to 3.63% at
the end of November.

* TAX-EFFICIENT INVESTING

One of the byproducts of active portfolio management is the generation of
capital gains distributions. When the fund sells a holding at a profit,
the gain must by law be passed to shareholders unless offset by capital
losses. Unlike income distributions, which are generally tax free, capital
gains are taxable at a 20% rate. Since shareholders in the fund generally
wish to limit the taxes they pay, we try to make our portfolio decisions
tax efficient by either trading less or offsetting capital gains with
losses. During the period just ended, the market afforded us ample
opportunity to make use of tax losses while accomplishing some of our
other objectives. The following is a good example. At the start of the
period, we bought $5 million worth of a Westmoreland County bond earning a
5.32% yield. By the end of the period, the price had declined enough so
that the yield, which moves in the opposite direction, had risen to 6.24%.
Just after the close of the period, we sold the Westmoreland issue at a
loss and purchased Bethlehem Water bonds yielding 6.24% and 6.23% with
maturity dates farther in the future. In short, we used the tax loss to
offset gains in other areas and secured a higher yield for a longer period
of time.

* OPTIMISTIC OUTLOOK FAVORS LONG-TERM BONDS

Our outlook is cautiously optimistic. Municipal bond yields have risen and
the fund is earning more income than just six months ago. Prices are cheap
in our estimation. We have taken advantage of this opportunity by
purchasing longer-term bonds that are more sensitive to changes in
interest rates. If rates change direction and start falling, the fund
should benefit. If rates rise further, we intend to add to our long-term
position. Either way, we believe the fund is well positioned for the
balance of fiscal year 2000.

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 11/30/99, there is no guarantee the fund will
continue to hold these securities in the future.

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
(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.

page of performance section for performance calculation method.


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 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.


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 guide to the financial statements

These sections of the report constitute the fund's financial
statements.

The fund's portfolio lists all the fund's investments and their values as
of the last day of the reporting period. Holdings are organized by asset
type and industry sector, country, or state to show areas of concentration
and diversification.

Statement of assets and liabilities shows how the fund's net assets and
share price are determined. All investment and noninvestment assets are
added together. Any unpaid expenses and other liabilities are subtracted
from this total. The result is divided by the number of shares to
determine the net asset value per share, which is calculated separately
for each class of shares. (For funds with preferred shares, the amount
subtracted from total assets includes the net assets allocated to
remarketed preferred shares.)

Statement of operations shows the fund's net investment gain or loss for
the reporting period. This is determined by adding up all the fund's
earnings -- from dividends and interest income -- and subtracting its
operating expenses. This statement also lists any net gain or loss the
fund realized on the sales of its holdings and -- for holdings that remain
in the portfolio -- any change in unrealized gains or losses over the
period.

Statement of changes in net assets shows how the fund's net assets were
affected by distributions to shareholders and by changes in the number of
the fund's shares. It lists distributions and their sources (net
investment income or realized capital gains) over the current reporting
period and the most recent fiscal year-end. The distributions listed here
may not match the sources listed in the Statement of operations because
the distributions are determined on a tax basis and may be paid in a
different period from the one in which they were earned.

Financial highlights provide an overview of the fund's investment results,
per-share distributions, expense ratios, net investment income ratios and
portfolio turnover in one summary table, reflecting the five most recent
reporting periods. In a semiannual report, the highlight table also
includes the current reporting period. For open-end funds, a separate
table is provided for each share class.

      contracts at November 30, 1999.

Notes to financial statements
November 30, 1999 (Unaudited)

Note 1
Significant accounting policies

Putnam Pennsylvania 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 and Pennsylvania personal
income tax as Putnam Investment Management, Inc., ("Putnam Management"),
the fund's manager, a wholly-owned subsidiary of Putnam Investments, Inc.,
believes is consistent with preservation of capital by investing primarily
in a diversified portfolio of Pennsylvania 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 higher than class A but lower than class B
shares.

Expenses of the fund are borne pro-rata by the holders of each class of
shares, except that each class bears expenses unique to that class
(including the distribution fees applicable to such class). Each class
votes as a class only with respect to its own distribution plan or other
matters on which a class vote is required by law or determined by the
Trustees. Shares of each class would receive their pro-rata share of the
net assets of the fund, if 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
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 six months
ended November 30, 1999, 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 paid monthly.Capital gain distributions, if any, are
recorded on the ex-dividend date and paid at least annually. The amount
and character of income and gains to be distributed are determined in
accordance with income tax regulations which may differ from generally
accepted accounting principles. Reclassifications are made to the fund's
capital accounts to reflect income and gains available for distribution
(or available capital loss carryovers) under income tax regulations.

G) 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. Discounts on zero coupon bonds and
original issue discount 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, 0.340% of the next $5 billion, and
0.330% thereafter. On June 4, 1999, the trustees approved a management fee
schedule which became effective on July 1, 1999, based upon the lesser of
(I) an annual rate of 0.50% of the average net asset value of the fund or
(ii) the initial tiers mentioned above.

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

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

For the six months ended November 30, 1999, fund expenses were reduced by
$26,059 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 $557 has
been allocated to the fund, and an additional fee for each Trustee's
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 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 six months ended November 30, 1999, Putnam Mutual Funds Corp.,
acting as underwriter received net commissions of $9,969 and $187 from the
sale of class A and class M shares, respectively and $134,889 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 November 30, 1999, Putnam Mutual
Funds Corp., acting as underwriter received no monies on class A
redemptions.

Note 3
Purchase and sales of securities

During the six months ended November 30, 1999, purchases and sales of
investment securities other than short-term investments aggregated
$7,263,824 and $19,024,327, respectively. There were no purchases and
sales of U.S. government obligations.
