Dear Shareholder:

It is a pleasure to greet you in our new roles as Chairman of the
Trustees and President of the Funds.  As you know, both of us have been
members of the Board of Trustees for a number of years -- years in which
Putnam has experienced tremendous growth and transformed itself from a
respected U.S. investment management firm to a financial institution
with a global presence.

As the organization makes its way into the new century, we are certain
that the changes that lie ahead will be even more breathtaking in their
scope. What will not change is the Trustees' dedication to serving the
best interests of our shareholders.

We embark upon this new era of Putnam's rich heritage with confidence
and we look forward to the opportunity of continuing to help you meet
your financial objectives for many years to come.

Respectfully yours,

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

John A. Hill                George Putnam, III

REPORT FROM THE FUND MANAGER

Susan A. McCormack

Compared with the stock market's roller-coaster ride in recent months,
the municipal market has been far less harrowing for tax-conscious
investors. Moreover, Ohio's robust manufacturing, retailing, and service
economy has continued to provide a solid backdrop for municipal
investors. Unfortunately, steady interest-rate increases throughout the
annual period have put a damper on municipal bond performance. Municipal
bond funds have also had to contend with cash outflows, as the stock
market's previously attractive returns have lured away some municipal
investors. Putnam Ohio Tax Exempt Income Fund has met these challenges
with solid income-generating strategies and prudent total return
management.

* MUNIS RETAIN VALUE AS TREASURIES STUMBLE AND STOCKS SELL OFF

When the stock market first began to exhibit weakness in early April,
fixed-income investments enjoyed price increases as nervous investors
flocked to bonds. The rise was short lived, however, as inflation
concerns and fears of continued interest-rate increases by the Federal
Reserve Board pushed down prices throughout the fixed-income market. The
good news is that municipal bond prices held up better than most other
fixed-income securities and continue to offer solid opportunity for
investors with tax considerations.

In fact, after wavering from a year of steady interest-rate increases,
the municipal bond market may slowly be approaching the point at which
the news gets better. It may not always appear to be a positive
attribute, but a responsible Fed that proactively seeks to contain
inflation is good news for bond investors. True, Fed policy and rising
interest rates have been the main reason for the choppy municipal bond
market this year, but if you look closely, you will notice that
municipal bond yields are actually not much higher and bond prices have
not gone much lower than they were in October 1999. Rather, the
short-term Treasury rates and mortgage interest rates have seen the
greatest movement.

It is difficult to know exactly when the economy will slow significantly
and interest rates will begin to fall, but we do know that the signs are
there: 30-year mortgage interest rates are over 8%, corporate bond rates
are approaching 9%, and the Nasdaq has been quite volatile. These three
statistics have historically  correlated with a weakening economy, a
slowdown in consumer spending, and lower interest rates.

* SEEKING HIGHER INCOME AMID WIDENING CREDIT SPREADS

Your fund has continued to provide a high level of tax-exempt income
throughout the fiscal year. Total return performance suffered somewhat,
however, as credit spreads between investment-grade municipal bonds and
higher-yielding issues widened over the past several months. This
widening put price pressure on interest-rate-sensitive sectors of the
market such as airlines and hospitals, which are well represented in the
fund's portfolio.


[GRAPHIC OMITTED: pie chart CREDIT QUALITY OVERVIEW]

CREDIT QUALITY OVERVIEW*

Aaa/AAA -- 48.9%

Aa/AA -- 8.7%

A -- 9.5%

Baa/BBB -- 23.0%

Ba/BB -- 7.8%

VMIG1 -- 2.1%

Footnote reads:
*As a percentage of market value as of 5/31/00. A bond rated BBB/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.


Continuing to extend the portfolio's duration was one effective way to
keep income strong over the period. As weakness in the bond market
persisted, we took advantage of falling bond prices to add some bonds
with higher yields and longer maturities, simultaneously selling bonds
in the intermediate-maturity range. Putnam has an experienced team of
credit analysts who add a great deal of value by enabling us to evaluate
those credits that are unrated by the major rating agencies. Their
expertise allows us to purchase securities whose current ratings may not
accurately reflect their performance potential, as well as undervalued
securities, with a higher degree of confidence.


For investors in Ohio's highest tax bracket, the fund's 5.27% 30-day SEC
yield for class A shares on May 31, 2000, was equivalent to a yield of
9.43% on a taxable investment.

See pages 6 and 7 for complete performance information.


During the period, we took advantage of recession-like credit spreads to
increase the fund's holdings of BBB/Baa-rated bonds. Normally a
BBB-rated bond yields just under a half percentage point more than a
AAA-rated bond, but now we are seeing a three-quarter-point difference
between the two bonds, an attractive yield difference that, in our view,
compensates investors for the somewhat higher risk inherent in a
BBB-rated bond. One noteworthy purchase the fund made in December
involved Baa2-rated bonds issued by the Toledo Lucas County Port
Authority for CSX Transportation to fund a new transfer station and iron
ore storage facility. Another was a position in Baa1-rated bonds issued
by Montgomery County for Kettering Medical Center to finance the
hospital's acquisition of two other hospitals, Grandview Hospital and
Southview Hospital. In both cases, the issuers are in solid financial
shape, the bonds pay excellent income, and the yields on the bonds were
more attractive than they would have been one year earlier. Both bonds
also offer solid price appreciation potential.


Fiscal policy? Monetary policy?

Fiscal policy refers to the federal government's use of spending and
taxation to control the economy. If the government raises taxes, people
will have less money to spend, therefore reducing demand. If the government
lowers taxes, people will be more inclined to spend money. The government
can also spend money to influence demand.

Monetary policy attempts to influence the economy by controlling the
money supply. Monetary policy is normally carried out by a central bank.
The central bank of the United States is the Federal Reserve. Monetary
policy can influence the economy by altering interest rates. By reducing
the supply of money, monetary policy can raise interest rates and
discourage lending. Decreased lending results in less investment and
less production.

Right now the Fed is implementing tighter monetary policy, and bond
funds, including municipal bonds, are not performing well.  This is a
result of the inverse relationship of interest rates and bond prices.
Treasury bonds take the brunt of the impact when interest rates rise,
while municipal bonds (attracting only domestic investors) are somewhat
insulated but by no means exempt.  Rising interest rates also affect the
supply of municipal bonds because cities and towns do not want to float
new bonds or refund outstanding bonds when interest rates are rising.

(First two paragraphs adapted from The Importance of Independence, by
David W. Gallivan.)


* POSITIONING FUND FOR WHAT LIES AHEAD

One of our goals in the past year, as rising interest rates caused bond
prices to decline, has been to create tax swaps. We have been realizing
capital losses by selling some securities purchased in previous years
when interest rates were lower. Then we have invested the proceeds in
higher yielding issues with comparable characteristics. The losses the
fund realizes on the sale of old securities will be available to offset
any future capital gains the fund may realize, which would otherwise be
taxable to shareholders. (Only the net investment income your fund earns
is tax exempt.)

Although the fund's overweight position in higher-yielding, lower-rated
bonds hurt performance when credit spreads widened so dramatically in
December and January, we continue to believe in the value of these
issues and in the performance potential of every bond in the portfolio.
Signs that the economy may be slowing are now emerging. If the change
takes hold and interest rates begin to drop, investors seeking higher
yields will likely push up demand for the kinds of bonds that form the
backbone of this portfolio. These higher-yielding bonds would then be
poised for solid price appreciation.

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 5/31/00, there is no guarantee the fund will
continue to hold these securities in the future.


PERFORMANCE SUMMARY

This section provides information about your fund's performance, which
should always be considered in light of its investment strategy. Putnam
Ohio Tax Exempt Income Fund is designed for investors seeking a high
level of current income free from federal and Ohio state income tax
consistent with preservation of capital.

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-, 10-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
may be more or less than those shown. They do not take into account any
adjustment for taxes payable on reinvested distributions. 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. See first
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 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 and may pose different risks than the fund.
Securities in the fund do not match those in the index and performance
will differ. It is not possible to invest directly in an index.

Consumer price index (CPI) is a commonly used measure of inflation; it
does not represent an investment return.


A GUIDE TO THE FINANCIAL STATEMENTS

These sections of the report, preceded by the Report of independent
accountants, constitute the fund's financial statements.

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

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

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

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

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


REPORT OF INDEPENDENT ACCOUNTANTS
For the fiscal year ended May 31, 2000

To the Trustees and Shareholders of
Putnam Ohio 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 Ohio Tax Exempt Income Fund (the "fund") at
May 31, 2000, and the results of its operations, the changes in its net
assets and the financial highlights for the periods indicated, in
conformity with accounting principles generally accepted in the United
States. 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 auditing standards
generally accepted in the United States, 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,
2000 by correspondence with the custodian, provide a reasonable basis
for the opinion expressed above.

  (a) Percentages indicated are based on net assets of $199,483,670.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to
      be the most recent ratings available at May 31, 2000 for the securities
      listed. Ratings are generally ascribed to securities at the time of
      issuance. While the agencies may from time to time revise such ratings,
      they undertake no obligation to do so, and the ratings do not
      necessarily represent what the agencies would ascribe to these
      securities at May 31, 2000. Securities rated by Putnam are indicated by
      "/P" and are not publicly rated. Ratings are not covered by the Report
      of independent accountants.

NOTES TO FINANCIAL STATEMENTS
May 31, 2000

Note 1
Significant accounting policies

Putnam Ohio 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 Ohio 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
portfolio of Ohio 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 year ended May 31, 2000, the fund had no borrowings against the
line of credit.

E) Federal taxes It is the policy of the fund to distribute all of its
income within the prescribed time and otherwise comply with the
provisions of the Internal Revenue Code applicable to regulated
investment companies. It is also the intention of the fund to distribute
an amount sufficient to avoid imposition of any excise tax under Section
4982 of the Internal Revenue Code of 1986, as amended. Therefore, no
provision has been made for federal taxes on income, capital gains or
unrealized appreciation on securities held nor for excise tax on income
and capital gains.

At May 31, 2000, the fund had a capital loss carryover of approximately
$1,234,000 available to offset future net capital gain, if any. The
amount of the carryover and the expiration dates are:

Loss Carryover    Expiration
--------------    ------------------
      $876,000    May 31, 2007
       358,000    May 31, 2008

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. For
the year ended May 31, 2000, the fund had no such reclassification.

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 lesser of (i) an annual rate of 0.50%
of the average net assets of the fund or (ii) the following annual
rates: 0.60% of the first $500 million of average net assets, 0.50% of
the next $500 million, 0.45% of the next $500 million, 0.40% of the next
$5 billion, 0.375% of the next $5 billion, 0.355% of the next $5
billion, 0.34% of the next $5 billion, and 0.33% thereafter. Prior to
July 1, 1999, the management fee was based on (ii) above. Through July
1, 1999, a management fee waiver of 0.10% on each tier was in effect.

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, 2000, fund expenses were reduced by $138,414
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 $553
has been allocated to the fund, and an additional fee for each Trustees
meeting attended. Trustees receive additional fees for attendance at
certain committee meetings.

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

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

The fund has adopted distribution plans (the "Plans") with respect to
its class A, class B and class M shares pursuant to Rule 12b-1 under the
Investment Company Act of 1940. The purpose of the Plans is to
compensate Putnam Retail Management, Inc., a wholly-owned subsidiary of
Putnam Investments Inc., for services provided and expenses incurred by
it in distributing shares of the fund. The Plans provide for payments by
the fund to Putnam Retail Management, Inc. at an annual rate up to
0.35%, 1.00% 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, 2000, Putnam Retail Management, Inc., acting
as underwriter received net commissions of $16,826 and $243 from the
sale of class A and class M shares, respectively, and $133,257 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 year ended May 31, 2000, Putnam Retail
Management, Inc., acting as underwriter received $6,794 on class A
redemptions that were purchased without an initial sales charge as part
of an investment of $1 million or more.

Note 3
Purchases and sales of securities

During the year ended May 31, 2000, cost of purchases and proceeds from
sales of investment securities other than short-term investments
aggregated $23,612,488 and $53,434,027, respectively. There were no
purchases or sales of U.S. government obligations.
