Dear Shareholder:

Because of their limited attractiveness to non-U.S. investors, municipal
bonds did not experience the turbulence endured by taxable bonds,
especially U.S. Treasury issues, in the wake of global investors' flight
to quality last fall. For U.S. investors, however, municipals have
provided unusually handsome current income both in real terms, thanks to
low inflation, and relative to after-tax returns on taxable securities,
especially for higher-bracket taxpayers.

Putnam Florida Tax Exempt Income Fund's management has been focusing on
generating maximum current income without undue risk to principal,
primarily through careful selection of portfolio holdings and strategies
aimed at risk reduction. Management is also cautiously seeking out bonds
with longer maturities and is currently focusing on noncallable bonds,
both moves designed to lock in attractive current returns.

I am pleased to announce the appointment of David E. Hamlin as your fund's
new manager. Before joining Putnam in 1998 as a senior portfolio manager,
he was with Vanguard Group, Provident Institutional Management Corp., and
Provident Bank. He has 17 years of investment experience.

Respectfully yours,

/S/GEORGE PUTNAM
George Putnam
Chairman of the Trustees
July 21, 1999



Report from the Fund Manager

David E. Hamlin

The municipal bond universe encountered many conflicting forces during the
year ended May 31, 1999. Falling and rising interest rates, tightening and
widening credit spreads, and dwindling supply in the face of steady demand
were just a few of the trends characterizing the period. With so many
complex market factors at play, maintaining a relatively stable price over
this period was a major challenge, but one that we feel has been
successfully met.

Total return for 12 months ended 5/31/99

* CAUTIOUS STANCE MUTES IMPACT OF RISING RATES

Bond market headlines currently belong to U.S. Treasuries, with the
long-term bond moving up to just about 6% as this report was being
written. This is the highest level for these bonds since spring of 1998.
Long-term municipal bond yields have risen too but not as dramatically,
illustrating the resistance of the municipal market to a rise in interest
rates. On June 2, 1999, the 30-year municipal bond yielded 5.375% -- 89.5%
of the Treasury yield -- which is clearly still an attractive ratio.

As interest rates have moved up, Putnam's municipal bond funds have
performed well, primarily due to our focus on the higher-yield sectors
(which outperformed the higher-grade sectors) and our overall cautious
stance toward interest rates during the year. We cannot predict when
interest rates will reach their peak, but we do believe that this is a
good time to begin incrementally lengthening maturities in the funds and
locking in higher rates.

*Based on net assets as of 5/31/99. Holdings will vary over time.


Concerns are gradually beginning to surface about the effects of Y2K and
Medicare reform proposals on certain sectors of the municipal bond market.
Such concerns are one reason why we have always considered security
selection and credit analysis crucial as a fundamental investment strategy
of the fund. Opportunity comes from choosing bonds correctly, not from
overall sector performance. Security and credit research have become even
more important when we invest in bonds that carry ratings below investment
grade. These are the bonds that can add tremendously to a fund's income
level, but they also mean taking on greater credit risk and require the
most meticulous research efforts.

One strategy we have used to maintain the relative stability of your
fund's net asset value involves an emphasis on discount and premium bonds.
Discount bonds trade below par value, which makes the purchase price of
these securities less than the value of the bond's face amount. Conversely
premium bonds trade above par, making the purchase price of these
securities more than the value of the bond's face amount. We have tried to
steer clear of bonds that are trading close to par. Once a bond's price
hovers around par, the bond starts to trade to its 10-year call date
rather than to its longer maturity date. Since investors assume the issuer
will call the bond and retire the debt, the bond's price fluctuates
dramatically. This is especially prevalent during periods of relatively
low interest rates as we have seen recently.

Baa/BBB -- 18.7%

Ba/BB -- 1.7%

Footnote reads:
* Based on a percentage of market value as of 5/31/99. A bond rated Baa or
  higher is considered investment grade. Percentages may include unrated
  bonds considered by Putnam Management to be of comparable quality. Ratings
  will vary over time.


* AMID TIGHT SUPPLY, GUAM AND PUERTO RICO BONDS PROVIDE DIVERSIFICATION

The level of new bond issuance dropped significantly in Florida this year,
mirroring a similar trend on the national level. From January through the
end of May, the supply of Florida municipal bonds declined more than 15%.
Given the heady pace of municipal bond offerings in 1998, it's likely that
many issuers have already addressed funding needs and that the supply will
consequently remain low for some time. The recent uptick in interest rates
is also responsible for a reduction in new offerings thus far in 1999.
Given the scarcity of new bonds coming to market, many investors are
holding on to their bonds, since there are few opportunities to replace
them. On the demand side, cash flow to municipal bonds has increased -- a
by-product of a volatile stock market and investors' need to rebalance
their portfolios. The ensuing supply/demand relationship is positive for
municipal bond prices and strengthens their resistance to rising interest
rates.


"Examine your needs for municipal bonds now. If you can use more, market
conditions are very favorable now. Technical factors built into the market
may make today's yields and spreads look very attractive in the future."

- -- "Munis Are Back," Northwestern Financial Review, March 20, 1999



A closer look at municipal credit ratings

Rating agencies such as Moody's Investors Service and Standard & Poor's Corp.
assign ratings to municipal issuers based on an in-depth analysis of the
issuer's financial condition and management, economic and debt
characteristics, and the specific revenue sources securing the bond. The
highest ratings are Aaa (Moody's) and AAA (Standard & Poor's). Bonds rated
in the Baa/BBB category or higher (A and Aa/AA) are considered to be
investment grade. Securities in the Ba/BB group and below are considered to
be below investment grade or high yield. If you look at "The fund's portfolio"
in the back of this report, you will see ratings next to each issuer's name.
The pie chart on page 3 summarizes this listing to give you a sense of the
portfolio's overall quality.

Sometimes smaller bonds are not rated because the cost of obtaining a rating
is not justifiable. Unrated bonds can still offer attractive investment
opportunities and may end up in your fund's portfolio. In such case, Putnam's
analysts perform their own ratings and the bonds are identified in the
portfolio listing by a /P rating.


During the period, we invested in Guam and Puerto Rico general obligation
bonds, adding valuable diversification and attractive total return
potential to the portfolio. Income from securities issued in U.S.
territories and commonwealths is tax free to U.S. investors. These
holdings have appreciated in response to growing demand.

* THREE SECTORS OFFER ATTRACTIVE OPPORTUNITIES

Within the Florida municipal market, we found attractive opportunities in
the health-care, transportation, and utility sectors. Cyprus Cove in Fort
Myers and Shell Point on Sanibel Island are two retirement communities
delivering high-quality health care to an aging population. Changing
demographics point to a bright future for both communities. Their bonds
carry coupons of 6 3/8% and 5 1/2%, respectively.

The utility industry is changing rapidly in response to deregulation and
increased competition, and change usually signals opportunity. Among
utility bonds, we prefer those issued by investor-owned companies, which
are for-profit entities and thus better equipped to compete in a
market-driven environment. Holdings in this sector are rated AAA, AA, or
insured. Florida Power and Light is one example.

The healthy economy, high passenger demand, and relatively low petroleum
prices continue to support strong performance for the airline-backed
industrial development bonds. Airlines are posting record profits and are
in the best fiscal shape of the decade. Current holdings include bonds
backed by American Airlines and Delta Airlines. While these holdings,
along with others discussed in this report, were viewed favorably during
the period, all holdings are subject to review in accordance with the
fund's investment strategy and may vary in the future.

* DESPITE RATE UPTICK, INFLATION REMAINS LOW

With indications that inflation may be starting to rise, the consumer
price index is moving toward an annualized core inflation rate of
approximately 2%. Since inflation in 1998 was practically nonexistent, a
move to 2% may seem tremendous but is actually well below what has been
considered average. And despite some signs of returning inflation, we
still live predominately in a deflationary world, one in which many prices
are falling. Just look at online stock trading prices and the discounts
available from online bookstores for evidence of deflation.

In the coming months, we expect that economic and market stability will be
more the rule than the exception. If rates continue to climb gradually as
we expect, the fund's multi-pronged investment strategy should continue to
yield positive results in the coming fiscal 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 5/31/99, 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-year, 5-year 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.

Past performance is no assurance of future results. More recent returns

Terms and definitions

Total return shows how the value of the fund's shares changed over time,
assuming you held the shares through the entire period and reinvested all
distributions in the fund.

Class A shares are generally subject to an initial sales charge.

Class B shares may be subject to a sales charge upon redemption.

Class M shares have a lower initial sales charge and a higher 12b-1 fee
than class A shares and no sales charge on redemption.

Net asset value (NAV) is the value of all your fund's assets, minus any
liabilities, divided by the number of outstanding shares, not including
any initial or contingent deferred sales charge.

Public offering price (POP) is the price of a mutual fund share plus the
maximum sales charge levied at the time of purchase. POP performance
figures shown here assume the 4.75% maximum sales charge for class A
shares and 3.25% for class M shares.

Contingent deferred sales charge (CDSC) is a charge applied at the time of
the redemption of class B shares and assumes redemption at the end of the
period. Your fund's CDSC declines from a 5% maximum during the first year
to 1% during the sixth year. After the sixth year, the CDSC no longer
applies.


Comparative benchmarks

Lehman Brothers Municipal Bond Index is an unmanaged list of long-term
fixed-rate investment-grade tax-exempt bonds representative of the
municipal bond market. The index does not take into account brokerage
commissions or other costs, may include bonds different from those in the
fund, and may pose different risks than the fund. 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 is determined. All investment and non-investment 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
amounts 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-ended funds, a separate table is
provided for each share class.



Report of independent accountants
For the fiscal year ended May 31, 1999

To the Trustees and Shareholders of
Putnam Florida Tax Exempt Income Fund

In our opinion, the accompanying statement of assets and liabilities,
including the fund's portfolio (except for bond ratings), and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial
position of Putnam Florida Tax Exempt Income Fund (the "fund") at May 31,
1999, and the results of its operations, the changes in its net assets and
the financial highlights for the periods indicated, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are
the responsibility of the fund's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with
generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting
principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of investments owned at May 31,
1999 by correspondence with the custodian, provide a reasonable basis for
the opinion expressed above.

Notes to financial statements
May 31, 1999

Note 1
Significant accounting policies

Putnam Florida Tax Exempt Income Fund (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 securities exempt from
the Florida intangibles tax.

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. 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 May
31, 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.

At May 31, 1999, the fund had a capital loss carryover of approximately
$1,133,000 available to offset future capital gains, if any. The amount of
the carryover and the expiration dates are:

Loss Carryover        Expiration
- --------------       ------------
      $221,000       May 31, 2003
       908,000       May 31, 2004
         4,000       May 31, 2005

F) Distributions to shareholders Income dividends are recorded daily by
the fund and are distributed monthly. Capital gain distributions, if any,
are recorded on the ex-dividend date and paid at least annually. The
amount and character of income and gains to be distributed are determined
in accordance with income tax regulations which may differ from generally
accepted accounting principles. These differences include temporary and
permanent differences of losses on wash sale transactions, dividends
payable, straddle loss deferrals and unrealized gains and losses on
certain futures contracts. 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 May 31, 1999, the fund reclassified $4,114 to decrease
undistributed net investment income and $4,114 to increase
paid-in-capital. 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. Discounts on zero coupon bonds and
original issue discount bonds are accreted according to the
yield-to-maturity basis.

Note 2
Management fee, administrative
services and other transactions

Compensation of Putnam Management, for management and investment advisory
services is paid quarterly based on the average net assets of the fund.
Such fee is based on the following annual rates: 0.60% of the first $500
million of average net assets, 0.50% of the next $500 million, 0.45% of
the next $500 million, 0.40% of the next $5 billion, 0.375% of the next $5
billion, 0.355% of the next $5 billion, 0.34% of the next $5 billion and
0.33% thereafter. On June 4, 1999, the Trustees approved a management fee
schedule to become effective 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 year ended May 31, 1999, fund expenses were reduced by $81,179
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 $390 has
been allocated to the fund, and an additional fee for each Trustee's
meeting attended. Trustees who are not interested persons of Putnam
Management and who serve on committees of the Trustees receive additional
fees for attendance at certain committee meetings.

The fund has adopted a Trustee Fee Deferral Plan (the "Deferral Plan")
which allows the Trustees to defer the receipt of all or a portion of
Trustees Fees payable on or after July 1, 1995. The deferred fees remain
in the fund and are invested in certain Putnam funds until distribution in
accordance with the Deferral Plan.

The fund has adopted an unfunded noncontributory defined benefit pension
plan (the "Pension Plan") covering all Trustees of the fund who have
served as Trustee for at least five years. Benefits under the Pension Plan
are equal to 50% of the Trustee's average total retainer and meeting fees
for the three years preceding retirement. Pension expense for the fund is
included in Compensation of Trustees in the Statement of operations.
Accrued pension liability is included in Payable for compensation of
Trustees in the Statement of assets and liabilities.

The fund has adopted distribution plans (the "Plans") with respect to its
class A, class B and class M shares pursuant to Rule 12b-1 under the
Investment Company Act of 1940. The purpose of the Plans is to compensate
Putnam Mutual Funds Corp., a wholly-owned subsidiary of Putnam Investments
Inc., for services provided and expenses incurred by it in distributing
shares of the fund. The Plans provide for payments by the fund to Putnam
Mutual Funds Corp. at an annual rate up to 0.35%, 1.00% and 1.00% of the
average net assets attributable to class A, class B and class M shares,
respectively. The Trustees have approved payment by the fund to an annual
rate of 0.20%, 0.85% and 0.50% of the average net assets attributable to
class A, class B and class M shares, respectively.

For the year ended May 31, 1999, Putnam Mutual Funds Corp., acting as
underwriter received net commissions of $50,272 and $437 from the sale of
class A and class M shares, respectively, and $143,456 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 that were purchased without an initial sales charge as part of an
investment of $1 million or more. For the year ended May 31, 1999, Putnam
Mutual Funds Corp., acting as underwriter received $18,386 on class A
redemptions.

Note 3
Purchase and sales of securities

During the year ended May 31, 1999, purchases and sales of investment
securities other than short-term investments aggregated $111,164,041 and
$100,007,998, 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.

Capital shares

At May 31, 1999, there was an unlimited number of shares of beneficial
interest authorized. Transactions in capital shares were as follows:
