Fund highlights

* "Given the state's strong economy and prospects for continued stable 
interest rates and low inflation, Florida municipalities may be less 
hesitant than those of other states to undertake debt for new projects. 
Even so, demand should remain high enough to absorb new issues as they 
come to market -- and to buoy the market for existing issues."

                               -- Leslie Burke, manager
                                  Putnam Florida Tax Exempt Income Fund

* "Munis from high-income-tax states such as California and Minnesota 
sell at a premium, with lower yields than bonds from income-tax-free 
states. Other locales to consider: New York and Florida, where the 
supply is heavier -- and yields may be higher -- than in other states."

Dear Shareholder:

The first half of Putnam Florida Tax Exempt Income Fund's fiscal 1997 
presented a significantly brighter municipal bond market environment 
than that which had prevailed in the preceding months. As the fiscal 
year's first half unfolded, the municipal bond market -- including the 
market for Florida 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, Leslie Burke was appointed your fund's manager. 
Leslie joined Putnam in 1992 as a credit analyst in the Tax-Exempt Bond 
Group. Before joining Putnam, she was with Fidelity Investments. She has 
10 years of investment experience.

In the report that follows, Leslie 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
Leslie J. Burke

Putnam Florida Tax Exempt Income Fund began its 1997 fiscal year last 
spring during a period of uncertainty in the municipal bond market. For 
the first three months, virtually every new economic statistic triggered 
waves of speculation about the direction of interest rates. In turn, 
bond prices, prompted by investors' reactions, fluctuated broadly. By 
autumn, however, the investment environment for bonds had improved, and 
bond prices had begun to rise. 

Because the fund had been well positioned to take advantage of the 
rally, it reached the fiscal year's midpoint on November 30, 1996, with 
total returns of 6.57%, 6.22%, and 6.29% for its class A, class B, and 
class M shares, respectively, at net asset value. Returns were 1.56%, 
1.22%, and 2.83%, respectively, at the maximum public offering price. 
Full performance details for other time periods can be found on pages 9 
and 10 of this report.

* SLOWING ECONOMY AND STRONG DEMAND SPARK MUNICIPAL BOND RALLY

After a difficult and volatile year, the municipal bond market shifted 
gears into a long-awaited rally in the fall. The U.S. economy's fast-
paced growth during calendar 1996's third quarter gave way to a 
projection of significantly slower growth for the final three months of 
the year. Economists expect this slowdown to continue into early l997. 
This cooling of economic growth soothed investors' concerns over the 
prospect of rising interest rates and helped lead fixed-income 
investments, including municipal bonds, to higher price levels.

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

In terms of supply, the market for municipal securities was relatively 
tight through the fiscal year's opening months. Traditionally, June and 
July are 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 supply of new bonds 
rose.

* MORE DEFENSIVE APPROACH SEEKS TO REDUCE PORTFOLIO VOLATILITY

Throughout the semiannual period, we maintained a strategy first put 
into place toward the end of fiscal l996, taking several steps to reduce 
the volatility of the portfolio. This more defensive strategy is 
designed to preserve the fund's net asset value, reduce its sensitivity 
to interest-rate changes, and enable it to continue providing 
shareholders with a relatively high level of tax-free income. To achieve 
these goals, we focused both on shortening the portfolio's overall 
duration and improving its call protection. 

Duration is a mathematical formula that indicates how much bond prices 
are likely to move up or down with each percentage-point shift in 
interest rates. Like maturity, duration is measured in years. Shorter 
durations generally go hand in hand with lower levels of volatility. 

To shorten the portfolio's duration, we redeployed assets to concentrate 
fund holdings in intermediate-term securities with maturities of 6 to 10 
years rather than splitting holdings between short- and long-term 
securities. Balancing longer-term holdings with shorter-term bonds is 
another way to achieve a shorter duration, but our assessment of current 
market conditions led us to use intermediate securities.

TOP INDUSTRY SECTORS*

Health care                21.1%

Utilities                  17.1%

Transportation             13.6%

Education                  12.8%

Housing                     8.3%

Footnote reads:
* Based on net assets as of 11/30/96. Sector allocations will vary over 
  time.

To protect your fund from early bond calls, we selectively replaced a 
portion of the portfolio's lower-coupon bonds that were approaching 
their call dates with bonds whose call dates were farther away and with 
higher-coupon noncallable bonds. We believe this action should provide 
your fund with the dual benefits of reducing call risk and enhancing the 
income stream.

* DESPITE SOME ROUGH AREAS, FLORIDA'S ECONOMY REMAINS SOLID

Even though Florida is currently coming to terms with a slight budget 
shortfall, the state's economy is in relatively good shape. In fact, it 
is currently part of the country's strongest region -- the Southeast. 
Florida continues to benefit from population growth and from the 
relocation of some corporations from other areas of the country. 

Economically, Miami is going through a difficult period. Because of a 
$69 million budget deficit, the city's general obligation bonds were 
recently downgraded to below investment-grade status. Although your fund 
does not own any Miami general obligation bonds, when such a situation 
occurs, we review as a matter of course all of the portfolio's holdings 
to make sure that other bonds in the portfolio will not be affected. In 
analyzing your fund's portfolio, we have determined that none of its 
current holdings are dependent on Miami's financial health. Of course, 
we will be closely monitoring the situation in Miami to see what effect, 
if any, its financial difficulties have on the rest of the state.

* HOSPITAL BONDS LEAD LIST OF RECURRING THEMES

Health care has been a consistent theme in the portfolio and a sector 
that has made a strong contribution to your fund's performance; many 
Florida hospitals are benefiting from the changing health-care 
environment. While nonprofit and for-profit hospitals exist in the 
state, Florida has evolved into a primarily for-profit health-care 
market, a factor that has particular implications for our security-
selection process. 



[GRAPHIC PIE CHART OMITTED: PORTFOLIO QUALITY OVERVIEW]

PORTFOLIO QUALITY OVERVIEW*

Ba--    1.5%

Baa--  16.0%

A--     9.7%

Aa--   12.7%

VMIG1-- 2.6%

B--     2.1%

Aaa--  55.4%

Footnote reads:
* As a percentage of market value as of 11/30/96. A bond rated Baa or  
  higher is considered investment grade. All ratings reflect Moody's 
  descriptions, unless noted otherwise; percentages may include unrated 
  bonds considered by Putnam Management to be of comparable quality. 
  Ratings will vary over time.

When we select a hospital bond for the portfolio, we evaluate its 
individual merits -- its credit quality, funding sources, and long-term 
prospects. However, we are also aware that many of the attractive 
nonprofit hospitals in the state may be appealing to profit-oriented 
institutions as future acquisition candidates. When a nonprofit hospital 
is acquired by a for-profit facility, the quality of the nonprofit's 
bonds is usually enhanced. More often than not, this upgraded quality is 
reflected in higher prices for the bonds. 

In examining other areas for investment opportunities, we continue to 
favor the cogeneration and resource-recovery sectors -- areas involved 
in recycling and converting trash to fuel. While both are relatively 
young industries, we believe the trend toward recycling will make them 
more valuable in the future. 

We have found infrastructure financing to be another important 
investment area. One success story is the fund's investment in the new 
Mid-Bay Bridge construction project. The fund has a meaningful position 
in the project's bonds, which were issued about three years ago. Not 
only did the new bridge open ahead of schedule, its financial condition 
has exceeded all projections. In addition, the quality and sturdiness of 
the bridge's construction have now been tested by two severe hurricanes 
which it withstood with no resulting damage. The success of the Mid-Bay 
Bridge construction project has contributed to the appreciation in value 
of its bonds.

* CONSTRUCTIVE, YET CAUTIOUS, OUTLOOK PREVAILS

Going forward, we expect economic growth to remain at a moderate level 
and interest rates to remain stable or move only slightly higher. We 
also expect inflation to remain relatively low.

As your fund enters the second half of fiscal l997, we 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 an inevitable 
tax consequence -- taxable capital gains from the sales of portfolio 
holdings that have risen in value. In keeping with the fund's objective 
of providing tax-free income, we plan to shift portfolio holdings only 
when the potential benefits will substantially outweigh the effects of 
any taxable distributions. 

Footnote reads:
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 summary

Performance should always be considered in light of a fund's investment 
strategy. Putnam Florida Tax Exempt Income Fund is designed for 
investors seeking a high level of current income free from federal tax 
consistent with preservation of capital by investing in securities 
exempt from the Florida intangibles tax. 

This section provides, at a glance, information about your fund's 
performance. 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. We show total 
return in two ways: on a cumulative long-term basis and on average how 
the fund might have grown each year over varying periods.

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 assumes reinvestment of all 
distributions and interest payments and does not take in account 
brokerage fees or taxes. 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.

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 non-diversified, open-end management investment company. 
The fund seeks as high a level of current income exempt from federal 
income tax as Putnam Investment Management ("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 portfolio of Florida 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 Manager 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.

At May 31, 1996, the fund had a capital loss carryover of approximately 
$4,236,000 available to offset future capital gains, if any. The amount 
of the carryover and the expiration dates are:

Loss Carryover                Expiration
- ------------------------------------------
  $ 218,000                   May 31, 2002
  3,111,000                   May 31, 2003
    907,000                   May 31, 2004

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 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, stepped-coupon 
bonds and original issue 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 
$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. 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 $159,991 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 $750 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 compensation 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 $13,620 and $177 from 
the sale of class A and class M shares, respectively and $63,376 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 no monies 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 
$75,661,455 and $87,090,706, 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.
