Dear Shareholder:

The first half of Putnam Pennsylvania Tax Exempt Income Fund's fiscal 
year 1997 presented a significantly brighter municipal bond market 
environment than that which had prevailed in the preceding months. As 
the fiscal year unfolded, the municipal bond market -- including the 
market for Pennsylvania tax-exempt bonds -- began to develop a sense of 
serenity, closing the semiannual period on November 30, 1996, in an 
almost upbeat mood. 

During the period, Howard Manning was appointed your fund's manager. 
Howard has 14 years of investment experience and has been a member of 
Putnam's municipal bond group since 1986.

In the report that follows, Howard discusses the events and strategies 
that drove your fund's performance during the fiscal year's first half 
and takes a look at prospects for the second half.

Respectfully yours, 

/S/George Putnam

George Putnam

Chairman of the Trustees

January 15, 1997


Report from the Fund Manager
Howard K. Manning

Moderate price gains in the municipal bond market and an attractive 
income stream from portfolio holdings combined to lead Putnam 
Pennsylvania Tax Exempt Income Fund to solid total returns for the 
semiannual period ended November 30, 1996. In the first six months of 
fiscal year 1997, class A, class B, and class M shares totaled 6.44%, 
5.98%, and 6.16%, respectively, all at net asset value (1.42%, 0.98%, 
and 2.66%, respectively, at public offering price). For additional 
performance information, including a look at your fund's taxable 
equivalent dividend rate -- the amount of income you would need from a 
taxable investment to equal your fund's distributions on an after-tax 
basis -- please refer to the performance summary that begins on page 9.

* SLOWING ECONOMY AND STRONG DEMAND SPARK MUNICIPAL BOND RALLY

After a difficult and volatile year, the municipal bond market shifted 
gears and rallied during your fund's semiannual period. The U.S. 
economy's fast-paced growth of 4.6% during the third quarter of calendar 
year 1996 gave way to a projection of 2.2% growth for the final three 
months of the year. Economists expect this slowdown to continue into 
early 1997. This cooling of economic growth soothed investors' concerns 
over rising interest rates and helped lead fixed-income investments, 
including municipal bonds, to higher price levels.

Strong demand also helped spur the period's market rally. While large 
numbers of individual investors in the United States focused their 
attention on the unprecedented gains in the stock market, overseas 
investors purchased upward of $175 billion in U.S. bonds -- an amount 
that exceeds the federal budget deficit. Although foreign investors -- 
ineligible for the tax benefits of U.S. municipal bonds -- invested 
primarily in Treasury securities, their interest sparked greater demand 
and, consequently, rising prices for the municipal market as well.

In terms of supply, the market for municipal securities was relatively 
tight through the first few months of the period. June and July are 
traditionally months in which many bonds mature or reach their call 
dates and September's municipal bond issuance was the lowest in more 
than a year. Autumn's lower interest rates, however, made bond issuance 
more attractive for cash-strapped municipalities, and the overall supply 
of new bonds rose slightly.

We capitalized on the positive performance of the municipal bond market 
by maintaining an above-market duration for the past six months. 
Duration is a measure of a portfolio's sensitivity to interest-rate 
changes. A longer duration can mean a more volatile net asset value if 
rates change -- but also one more likely to appreciate substantially if 
rates decline. A shorter duration can help preserve portfolio value as 
interest rates rise. Your fund's longer duration helped boost 
performance during the period as interest rates on medium- and long-term 
municipal bonds dropped by 46 and 50 basis points, respectively.

* CREDIT RESEARCH CRUCIAL TO PORTFOLIO STRUCTURE

We continue to emphasize investments in the health-care sector of the 
municipal bond market. Consolidations, improved methods of cost 
containment, and a near-total lack of new hospital construction are some 
of the key factors supporting our favorable view of this sector's 
potential. In addition to the traditional hospital holdings, our 
investments include demographically attractive geriatric care facilities 
such as nursing homes and retirement communities. Since beginning our 
focus on this sector two years ago, our analysts have become adept at 
identifying uninsured health-care bonds with steady revenue streams and 
strong potential for credit upgrades or prerefunding.

Prerefunding occurs when an issuer floats a bond to raise capital to pay 
off, or retire, an older bond. The proceeds from the newer issue are 
held in top-quality short-term instruments until the old debt can be 
retired, usually at its first call date. The typical effect of a 
prerefunding is the same as that of an actual credit upgrade -- price 
appreciation. In the meantime, these issues make up some of your 
portfolio's core yield holdings.

Montgomery County United Hospital bonds are one such holding. Mentioned 
in your fund's most recent annual report as a possible prerefunding 
candidate, these bonds offered an 8 1/4% coupon and a B rating when we 
originally purchased them. Today, after having been prerefunded, they 
carry that same attractive level of income and a AAA rating. Thanks to 
our in-depth credit research, we were able to identify these bonds as a 
worthwhile purchase despite their initial lower rating. While these 
bonds, along with others discussed in the report, were viewed favorably 
at the end of the semiannual period, all portfolio holdings are subject 
to review and adjustment in accordance with the fund's investment 
strategy and may vary in the future.

The relatively light supply of Pennsylvania municipal bonds adds an 
extra challenge to our attempts to identify holdings that meet your 
fund's stringent investment criteria and fit into our desired portfolio 
structure. Although our monthly surveillance meetings are designed, in 
part, to highlight attractive market sectors, it is rarely possible for 
us to build up a significant weighting in a promising sector as soon as 
we identify it as such. Instead, our analysts scour the new-issue and 
secondary markets on a daily basis, allowing us to acquire portfolio 
holdings whenever we find what we believe to be the right balance of 
price, credit quality, yield, and potential reward. Recently, issues 
from U.S. Steel and a City of Philadelphia Parking Garage bond exhibited 
this blend of factors and were added to your fund's portfolio.

bonds considered by Putnam Management to be of comparable quality. 
Ratings will vary over time.

* CONSTRUCTIVE, YET CAUTIOUS, OUTLOOK PREVAILS

After the market's positive performance during the past six months, we 
now believe municipal bonds may be fully priced and are scaling back 
your portfolio's duration accordingly. We are also aiming to re-position 
the portfolio from a barbell structure, which favors holdings in both 
short- and long-term bonds, to one that emphasizes bonds in the 15- to 
20-year maturity range, where we expect to find better values. Seeking 
improved call protection is another of our priorities, intended to help 
protect your fund against the loss of bonds in a falling interest-rate 
environment. 

As your fund enters the second half of fiscal year 1997, our large staff 
of experienced research analysts will continue to scrutinize existing 
and new municipal bond issues to find securities that will contribute to 
your fund's stream of tax-exempt income. In a post-rally environment, 
however, we must remain mindful of another tax consequence -- capital 
gains from the sales of portfolio holdings that have risen in value. 
Although it is unlikely that any fund could avoid capital gains 
altogether, we plan to shift portfolio holdings only when the benefits 
will substantially outweigh the potential effects of any taxable 
distributions.

Pre-election talks of sweeping tax reforms, such as the flat tax and the 
elimination of the Internal Revenue Service, have been shelved, most 
likely for the duration of the current administration. Although we 
remain aware that these issues are merely dormant, not dead, the short-
term outlook for tax-advantaged income investments remains constructive. 

Footnote reads:s
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 11/30/96, there is no guarantee the fund 
will continue to hold these securities in the future.

Performance data represent past results, do not reflect future 
performance, and will differ for each share class. They do not take into 
account any adjustment for taxes payable on reinvested distributions or 
for distribution fees prior to implementation of the class A 
distribution plan in 1990. Investment returns and principal value will 
fluctuate so that an investor's shares, when sold, may be worth more or 
less than their original cost. POP assumes 4.75% maximum sales charge 
for class A shares and 3.25% for class M shares. CDSC for class B shares 
assumes the applicable sales charge, with the maximum being 5%.

TERMS AND DEFINITIONS

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.

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. 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.

Notes to financial statements
November 30, 1996 (Unaudited)

Note 1 
Significant accounting policies

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 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 the Putnam Management 
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.

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) 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. 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.

E) 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 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.

F) Amortization of bond premium and accretion of bond discount Any 
premium resulting from the purchase of securities in excess of maturity 
value 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. Discounts on zero coupon bonds are accreted according to 
the effective yield method.

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, 0.50% of the next $500 million, 0.45% of the next 
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. Prior to September 20, 1996, any amount over $1.5 billion 
was based on 0.40%.

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

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

For the six months ended November 30, 1996, fund expenses were reduced 
by $109,518 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.

Trustees of the fund receive an annual Trustees fee of $740 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 adopted a Trustee Fee Deferral Plan (the "Plan") which allows 
the Trustees to defer the receipt of all or a portion of Trustees Fees 
payable on or after July 1, 1995. The deferred fees remain in the fund 
and are invested in certain Putnam funds until distribution in 
accordance with the 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 have approved payment 
by the fund at 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, 1996, Putnam Mutual Funds Corp., 
acting as underwriter received net commissions of $18,002 and $353 from 
the sale of class A and class M shares, respectively and $65,755 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, 1996, Putnam 
Mutual Funds Corp., acting as underwriter received $18 on class A 
redemptions.

Note 3
Purchase and sales of securities

During the six months ended November 30, 1996, purchases and sales of 
investment securities other than short-term investments aggregated 
$41,551,411 and $31,932,971, respectively. There were no purchases and 
sales of U.S. government obligations. 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 November 30, 1996, there was an unlimited number of shares of 
beneficial interest authorized. Transactions in capital shares were as
