Consider these risks before investing: Bond prices may fall or fail to rise over time for several reasons, including general financial market conditions, changing market perceptions of the risk of default, changes in government intervention in the financial markets, and factors related to a specific issuer. These and other factors may also lead to periods of high volatility and reduced liquidity in the bond markets. Single-state investments are at risk of common economic forces and other factors affecting a state’s tax-exempt investments. This may result in greater losses and volatility. Capital gains, if any, are taxed at the federal and, in most cases, state levels. For some investors, investment income may be subject to the federal alternative minimum tax. Bond investments are subject to interest-rate risk (the risk of bond prices falling if interest rates rise) and credit risk (the risk of an issuer defaulting on interest or principal payments). Interest-rate risk is greater for longer-term bonds, and credit risk is greater for below-investment-grade bonds. Unlike bonds, funds that invest in bonds have fees and expenses. Tax-exempt bonds may be issued under the Internal Revenue Code only by limited types of issuers for limited types of projects. As a result, the fund’s investments may be focused in certain market segments and be more vulnerable to fluctuations in the values of the securities it holds than a more broadly invested fund. Interest the fund receives might be taxable. You can lose money by investing in the fund.

Message from the Trustees

July 12, 2017

Dear Fellow Shareholder:

An impressive level of investor optimism has helped to fuel financial markets through the first half of 2017, and global stock and bond markets have generally fared well. At the same time, however, a number of macroeconomic and political risks around the world could disrupt the positive momentum.

While calm markets are generally welcome, we believe investors should continue to remember time-tested strategies: maintain a well-diversified portfolio, keep a long-term view, and speak regularly with your financial advisor. In the following pages, you will find an overview of your fund’s performance for the reporting period as well as an outlook for the coming months.

We would like to take this opportunity to announce some changes to your fund’s Board of Trustees. First, we are pleased to welcome the arrival of Catharine Bond Hill and Manoj P. Singh, who bring extensive professional and directorship experience to their new roles as Putnam Trustees. In addition, we would like to extend our appreciation and best wishes to Robert J. Darretta, John A. Hill, and W. Thomas Stephens, who retired from the Board, effective June 30, 2017. We are grateful for their years of work on behalf of you and your fellow shareholders, and we wish them well in their future endeavors.

Thank you for investing with Putnam.

Municipal bonds finance important public projects, such as schools, roads, and hospitals. The bonds are backed by either the issuing city, town, or other government entity or by revenues collected from usage fees.

However, unlike U.S. Treasuries or corporate bonds, the interest paid on municipal bonds is generally free from federal income taxes. Moreover, Ohio residents generally pay no state income taxes on distributions paid from municipal bonds issued in the Buckeye State. That can make municipal bonds particularly attractive to investors subject to higher personal income tax rates.

Putnam Ohio Tax Exempt Income Fund offers an active,
research-intensive investment approach.

Source: Putnam, as of 5/31/17. Past performance is no guarantee of future results. Yields for U.S. Treasuries, investment-grade corporates, and municipal bonds are represented by the average “yield to worst” — a calculation of the lowest possible yield generated without defaulting — of the Bloomberg Barclays U.S. Treasury Index, the Bloomberg Barclays U.S. Credit Index, and the Bloomberg Barclays Municipal Bond Index, respectively. You cannot invest directly in an index. Bond investments are subject to interest-rate risk (the risk of bond prices falling if interest rates rise) and credit risk (the risk of an issuer defaulting on interest or principal payments). Interest-rate risk is greater for longer-term bonds, and credit risk is greater for below-investment-grade bonds. Income from municipal bonds may be subject to the alternative minimum tax. Taxable equivalent yield and annual after-tax income are based on a 43.40% federal income tax rate. This rate reflects the American Taxpayer Relief Act of 2012 and includes the 3.80% Medicare surtax.

Current performance may be lower or higher than the quoted past performance, which cannot guarantee future results. Share price, principal value, and return will fluctuate, and you may have a gain or a loss when you sell your shares. Performance of class A shares assumes reinvestment of distributions and does not account for taxes. Fund returns in the bar chart do not reflect a sales charge of 4.00%; had they, returns would have been lower. See below and pages 10–13 for additional performance information. For a portion of the periods, the fund had expense limitations, without which returns would have been lower. To obtain the most recent month-end performance, visit putnam.com.

Paul holds a B.A. from Suffolk University. Paul has been in the investment industry since he joined Putnam in 1989.

In addition to Paul, your fund is managed by Garrett L. Hamilton, CFA. Garrett holds an M.S. in Investment Management from Boston University and a B.S. in International Business Administration from Southern New Hampshire University. He joined Putnam in 2016 and has been in the investment industry since 2006.

Paul, how was the market environment for municipal bonds during the reporting period?

Municipal bonds started the reporting period in solid fashion, benefiting from falling U.S. Treasury, municipal, and global interest rates and, in some cases, negative yields on non-U.S. sovereign bonds. Negative yields motivated many income-oriented investors to look beyond more traditional fixed-income investments.

During the fourth quarter of 2016, weaker supply/demand dynamics, higher interest rates, and President Trump’s pro-growth agenda weighed on municipal bond performance. From a demand perspective, mutual fund outflows, a measure of investor demand, increased following the presidential election. This was notable as fund flows were strongly positive for most of 2016. In our view, municipal bonds appeared to be pricing in President Trump’s economic stimulus agenda, which many economists believe could lead to improved growth in the United States, higher deficits, and possibly an uptick in inflation, as well as improving global growth. We believe the uncertainty around U.S. income tax policy changes for

individuals and corporations was an additional headwind for the asset class post-election. The spike in overall new issuance was due in part to the decision by many issuers to come to market with their municipal bond offerings ahead of the U.S. presidential election and a potential year-end interest-rate hike by the Federal Reserve, which occurred on December 14. As a result, 2016 proved to be a record-setting year for municipal bond issuance.

From January to May 2017, investor sentiment generally improved, especially for higher-yielding municipal bonds. The pace of new issuance was generally light, and demand slightly outpaced supply — contributing to rising prices and a narrowing of credit spreads of lower investment-grade as well as high-yield municipal bonds. [Credit spreads reflect the difference in yield between higher- and lower-quality municipal bonds.] Viewed in a longer-term context, the tighter spreads seemed relatively fair to us, especially considering that defaults among municipal issuers remained low and isolated.

With an unemployment rate below 4.5%, consumer and business confidence rising, and the U.S. economic backdrop improving, the Fed announced on June 14, 2017, its second interest-rate hike of 2017 and fourth since December 2015. In its assessment of inflation, the Fed revised its expectations downward, adding that it believed inflation would “remain somewhat below 2% in the near term.” Additionally, the Fed announced it will begin the process this year of reducing its $4.5 billion balance sheet, which the central bank increased by buying bonds and other securities to buttress the financial system during the housing crisis.

How did the fund perform?

For the 12 months ended May 31, 2017, the fund underperformed its benchmark index and its Lipper peer group average. The fund’s position in municipal bonds issued by FirstEnergy Solutions was negatively affected when its parent company announced possible restructuring plans.

What was your investment approach in this environment?

Given the market backdrop, many of our investment themes remained in place. We maintained an overweight exposure to lower-investment-grade municipal bonds and placed greater focus on higher-education, transportation, and continuing-care retirement community bonds relative to the Lipper group. However, we moved to a somewhat less defensive duration posture during the period, thereby slightly increasing the fund’s interest-rate sensitivity. As such, the fund’s duration positioning remained slightly below the median of the Lipper peer group.

During the reporting period, we maintained an underweight position in Puerto Rico-based issuers relative to the fund’s Lipper peers, given Puerto Rico’s weak credit fundamentals, in our view. On May 3, 2017, the federal control board petitioned for court-supervised debt restructuring under Title III of the Puerto Rico Oversight, Management and Economic Stability Act [PROMESA]. While PROMESA is not a bailout from the federal government, it did provide a way for Puerto Rico to use a bankruptcy-like restructuring tool similar to Chapter 9.

The recent move by Puerto Rico represents the largest bankruptcy in the history of U.S. public finance, exceeding Detroit’s 2013 insolvency. Despite the resulting flurry of headlines, we had anticipated this outcome. The filing does not change our current view on Puerto Rico, which is to maintain an underweight position in these bonds. In our view, we are likely to see more headline risk as Congress works with the government of Puerto Rico to come up

with a debt repayment plan that creditors can accept and that can help build a foundation for economic recovery in the coming years.

What is your current assessment of the potential for tax reform, and how might you steer the fund given that possibility?

Just before the close of the reporting period, the Trump administration presented its tax plan. More details are needed to fully assess the impact of the proposal, and the final plan may be considerably different from the initial tax plan now winding through Congress. However, the proposed plan reduces the overall number of individual tax brackets to three, eliminates targeted tax breaks and special interest, and repeals the alternative minimum tax, among other things. The good news for tax-sensitive investors, in our view, is that the tax-exempt status of municipal bonds wasn’t addressed in the recently announced tax outline. Treasury Secretary Mnuchin recently stated, “Our preference is strongly to keep the interest deductibility of state and local bonds.” (May 25, 2017). Furthermore, we do not believe the currently proposed lowering of the highest personal income tax bracket from 39.6% to 35% will materially affect demand for municipal bonds.

The new administration has stated that tax reform remains a major policy goal. However, we have not seen major tax reform in over 30 years, and we believe it will continue to be difficult to achieve any such reform today given the competing demands on the current administration. As such, we believe it is too early to boldly position the fund. That said, we continue to closely monitor tax policy developments in Washington to see what form the final tax plan may take, and how it may shape the outlook for municipal bonds.

What are your thoughts about Fed policy for the balance of 2017?

We anticipate a continuation of slow, steady improvement in U.S. and global economic growth in the year ahead. The global growth environment continues to be positive, in our view, and we are encouraged by the breadth of the growth.

This chart shows how the fund’s top weightings have changed over the past six months. Allocations are shown as a percentage of the fund’s net assets. Current period summary information may differ from the information in the portfolio schedule notes included in the financial statements due to the inclusion of derivative securities, any interest accruals, the use of different classifications of securities for presentation purposes, and rounding. Holdings and allocations may vary over time.

In our view, the market also appears to be focused on how much fiscal stimulus might come from the new administration, and how those initiatives will affect the pulse of the U.S. economy. Should additional stimulus augment U.S. growth, we believe the Fed might be inclined to tighten a little faster, or, conversely, tighten more slowly if fiscal policy proves less stimulative.

Thank you, Paul, for your time and insights today.

Current performance may be lower or higher than the quoted past performance, which cannot guarantee future results. After-sales-charge returns for class A and M shares reflect the deduction of the maximum 4.00% and 3.25% sales charge, respectively, levied at the time of purchase. Class B share returns after contingent deferred sales charge (CDSC) reflect the applicable CDSC, which is 5% in the first year, declining over time to 1% in the sixth year, and is eliminated thereafter. Class C share returns after CDSC reflect a 1% CDSC for the first year that is eliminated thereafter. Class Y shares have no initial sales charge or CDSC. Performance for class B, C, M, and Y shares before their inception is derived from the historical performance of class A shares, adjusted for the applicable sales charge (or CDSC) and the higher operating expenses for such shares, except for class Y shares, for which 12b-1 fees are not applicable.

For a portion of the periods, the fund had expense limitations, without which returns would have been lower.

Class B share performance reflects conversion to class A shares after eight years.

Terms and definitions

Important terms

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.

Before sales charge, or net asset value, is the price, or value, of one share of a mutual fund, without a sales charge. Before-sales-charge figures fluctuate with market conditions, and are calculated by dividing the net assets of each class of shares by the number of outstanding shares in the class.

After sales charge is the price of a mutual fund share plus the maximum sales charge levied at the time of purchase. After-sales-charge performance figures shown here assume the 4.00% maximum sales charge for class A shares and 3.25% for class M shares.

Contingent deferred sales charge (CDSC) is generally a charge applied at the time of the redemption of class B or C shares and assumes redemption at the end of the period. Your fund’s class B CDSC declines over time from a 5% maximum during the first year to 1% during the sixth year. After the sixth year, the CDSC no longer applies. The CDSC for class C shares is 1% for one year after purchase.

Share classes

Financial statements

These sections of the report, as well as the accompanying Notes, preceded by the Report of Independent Registered Public Accounting Firm, 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 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 liquidation preference of preferred shares.)

Statement of operations shows the fund’s net investment gain or loss. This is done by first adding up all the fund’s earnings — from dividends and interest income — and subtracting its operating expenses to determine net investment income (or loss). Then, any net gain or loss the fund realized on the sales of its holdings — as well as any unrealized gains or losses over the period — is added to or subtracted from the net investment result to determine the fund’s net gain or loss for the fiscal year.

Statement of changes in net assets shows how the fund’s net assets were affected by the fund’s net investment gain or loss, 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 highlights table also includes the current reporting period.

Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of
Putnam Ohio Tax Exempt Income Fund:

In our opinion, the accompanying statement of assets and liabilities, including the portfolio, 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”) as of May 31, 2017, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. 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 the standards of the Public Company Accounting Oversight Board (United States). Those standards 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. Our procedures included confirmation of securities owned as of May 31, 2017 by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Within the following notes to the portfolio, references to “ASC 820” represent Accounting Standards Codification 820 Fair Value Measurements and Disclosures, references to “Putnam Management” represent Putnam Investment Management, LLC, the fund’s manager, an indirect wholly-owned subsidiary of Putnam Investments, LLC and references to “OTC”, if any, represent over-the-counter.

^**The Moody’s, Standard & Poor’s or Fitch ratings indicated are believed to be the most recent ratings available at the close of the reporting period 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 the close of the reporting period. Securities rated by Fitch are indicated by “/F.” Securities rated by Putnam are indicated by “/P.” The Putnam rating categories are comparable to the Standard & Poor’s classifications. If a security is insured, it will usually be rated by the ratings organizations based on the financial strength of the insurer. Ratings are not covered by the Report of Independent Registered Public Accounting Firm. For further details regarding security ratings, please see the Statement of Additional Information.

144A after the name of an issuer represents securities exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These securities may be resold in transactions exempt from registration, normally to qualified institutional buyers.

On Mandatory Put Bonds, the rates shown are the current interest rates at the close of the reporting period and the dates shown represent the next mandatory put dates.

The dates shown parenthetically on prerefunded bonds represent the next prerefunding dates.

The dates shown on debt obligations are the original maturity dates.

The fund had the following sector concentrations greater than 10% at the close of the reporting period
(as a percentage of net assets):


Education	19.1%

Prerefunded	16.2

Local debt	15.7

Healthcare	15.7

Utilities	13.8

ASC 820 establishes a three-level hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of the fund’s investments. The three levels are defined as follows:

Level 1: Valuations based on quoted prices for identical securities in active markets.

Level 2: Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3: Valuations based on inputs that are unobservable and significant to the fair value measurement.

The following is a summary of the inputs used to value the fund’s net assets as of the close of the reporting period:


		Valuation inputs

Investments in securities:	Level 1	Level 2	Level 3

Municipal bonds and notes	$—	$133,559,502	$—

Totals by level	$—	$133,559,502	$—

During the reporting period, transfers within the fair value hierarchy, if any, did not represent, in the aggregate, more than 1% of the fund’s net assets measured as of the end of the period. Transfers are accounted for using the end of period pricing valuation method.

Notes to financial statements 5/31/17

Within the following Notes to financial statements, references to “State Street” represent State Street Bank and Trust Company, references to “the SEC” represent the Securities and Exchange Commission, references to “Putnam Management” represent Putnam Investment Management, LLC, the fund’s manager, an indirect wholly-owned subsidiary of Putnam Investments, LLC and references to “OTC”, if any, represent over-the-counter. Unless otherwise noted, the “reporting period” represents the period from June 1, 2016 through May 31, 2017.

Putnam Ohio Tax Exempt Income Fund (the fund) is a Massachusetts business trust, which is registered under the Investment Company Act of 1940, as amended, as a diversified open-end management investment company. The goal of the fund is to seek as high a level of current income exempt from federal income tax and Ohio personal income tax as Putnam Management believes is consistent with preservation of capital. The fund invests mainly in bonds that pay interest that is exempt from federal income tax and Ohio personal income tax (but that may be subject to federal alternative minimum tax (AMT)), are investment-grade in quality, and have intermediate- to long-term maturities (i.e., three years or longer). Under normal circumstances, Putnam Management invests at least 80% of the fund’s net assets in tax-exempt investments. This investment policy cannot be changed without the approval of the fund’s shareholders. Tax-exempt investments are issued by or for states, territories or possessions of the United States or by their political subdivisions, agencies, authorities or other government entities, and the income from these investments is exempt from both federal and the applicable state’s income tax. Interest income from private activity bonds may be subject to federal AMT for individuals. These investments are not included for the purpose of complying with the 80% investment policy. Putnam Management may consider, among other factors, credit, interest rate and prepayment risks, as well as general market conditions, when deciding whether to buy or sell investments.

The fund offers class A, class B, class C, class M and class Y shares. The fund registered class T shares in February 2017, however, as of the date of this report, class T shares had not commenced operations and are not available for purchase. Effective April 1, 2017, purchases of class B shares are closed to new and existing investors except by exchange from class B shares of another Putnam fund or through dividend and/or capital gains reinvest-ment. Class A and class M shares are sold with a maximum front-end sales charge of 4.00% and 3.25%, respectively. Class A shares generally are not subject to a contingent deferred sales charge, and class M and class Y shares are not subject to a contingent deferred sales charge. Class B shares, which convert to class A shares after approximately eight years, are not subject to a front-end sales charge and are subject to a contingent deferred sales charge if those shares are redeemed within six years of purchase. Class C shares are subject to a one-year 1.00% contingent deferred sales charge and do not convert to class A shares. The expenses for class A, class B, class C, and class M shares may differ based on the distribution fee of each class, which is identified in Note 2. Class Y shares, which are sold at net asset value, are generally subject to the same expenses as class A, class B, class C, and class M shares, but do not bear a distribution fee. Class Y shares are not available to all investors.

In the normal course of business, the fund enters into contracts that may include agreements to indemnify another party under given circumstances. The fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be, but have not yet been, made against the fund. However, the fund’s management team expects the risk of material loss to be remote.

The fund has entered into contractual arrangements with an investment adviser, administrator, distributor, shareholder servicing agent and custodian, who each provide services to the fund. Unless expressly stated otherwise, shareholders are not parties to, or intended beneficiaries of these contractual arrangements, and these contractual arrangements are not intended to create any shareholder right to enforce them against the service providers or to seek any remedy under them against the service providers, either directly or on behalf of the fund.

Under the fund’s Declaration of Trust, any claims asserted against or on behalf of the Putnam Funds, including claims against Trustees and Officers, must be brought in state and federal courts located within the Commonwealth of Massachusetts.

Note 1: Significant accounting policies

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 accounting principles generally accepted in the United States of America and requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and the reported amounts of increases and decreases in net assets from operations. Actual results could differ from those estimates. Subsequent events after the Statement of assets and liabilities date through the date that the financial statements were issued have been evaluated in the preparation of the financial statements.


32 Ohio Tax Exempt Income Fund

Investment income, realized and unrealized gains and losses and expenses of the fund are borne pro-rata based on the relative net assets of each class to the total net assets of the fund, except that each class bears expenses unique to that class (including the distribution fees applicable to such classes). 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. If the fund were liquidated, shares of each class would receive their pro-rata share of the net assets of the fund. In addition, the Trustees declare separate dividends on each class of shares.

Security valuation Portfolio securities and other investments are valued using policies and procedures adopted by the Board of Trustees. The Trustees have formed a Pricing Committee to oversee the implementation of these procedures and have delegated responsibility for valuing the fund’s assets in accordance with these procedures to Putnam Management. Putnam Management has established an internal Valuation Committee that is responsible for making fair value determinations, evaluating the effectiveness of the pricing policies of the fund and reporting to the Pricing Committee.

Tax-exempt bonds and notes are generally valued on the basis of valuations provided by an independent pricing service approved by the Trustees. Such services use information with respect to transactions in bonds, quotations from bond dealers, market transactions in comparable securities and various relationships between securities in determining value. These securities will generally be categorized as Level 2.

Certain investments, including certain restricted and illiquid securities and derivatives, are also valued at fair value following procedures approved by the Trustees. To assess the continuing appropriateness of fair valuations, the Valuation Committee reviews and affirms the reasonableness of such valuations on a regular basis after considering all relevant information that is reasonably available. Such valuations and procedures are reviewed periodically by the Trustees. These valuations consider such factors as significant market or specific security events such as interest rate or credit quality changes, various relationships with other securities, discount rates, U.S. Treasury, U.S. swap and credit yields, index levels, convexity exposures, recovery rates, sales and other multiples and resale restrictions. These securities are classified as Level 2 or as Level 3 depending on the priority of the significant inputs. The fair value of securities is generally determined as the amount that the fund could reasonably expect to realize from an orderly disposition of such securities over a reasonable period of time. By its nature, a fair value price is a good faith estimate of the value of a security in a current sale and does not reflect an actual market price, which may be different by a material amount.

Security transactions and related investment income Security transactions are recorded on the trade date (the 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. All premiums/discounts are amortized/accreted on a yield-to-maturity basis. The premium in excess of the call price, if any, is amortized to the call date; thereafter, any remaining premium is amortized to maturity.

Interfund lending The fund, along with other Putnam funds, may participate in an interfund lending program pursuant to an exemptive order issued by the SEC. This program allows the fund to borrow from other Putnam funds that permit such transactions. Interfund lending transactions are subject to each fund’s investment policies and borrowing and lending limits. Interest earned or paid on the interfund lending transaction will be based on the average of certain current market rates. During the reporting period, the fund did not utilize the program.

Lines of credit The fund participates, along with other Putnam funds, in a $317.5 million unsecured committed line of credit and a $235.5 million unsecured uncommitted line of credit, both provided by State Street. Borrowings may be made for temporary or emergency purposes, including the funding of shareholder redemption requests and trade settlements. Interest is charged to the fund based on the fund’s borrowing at a rate equal to the higher of (1) the Federal Funds rate and (2) the overnight LIBOR plus 1.25% for the committed line of credit and the Federal Funds rate plus 1.30% for the uncommitted line of credit. A closing fee equal to 0.04% of the committed line of credit plus a $25,000 flat fee and 0.04% of the uncommitted line of credit has been paid by the participating funds. In addition, a commitment fee of 0.21% per annum on any unutilized portion of the committed line of credit is allocated to the participating funds based on their relative net assets and paid quarterly. During the reporting period, the fund had no borrowings against these arrangements.

Federal taxes It is the policy of the fund to distribute all of its income within the prescribed time period and otherwise comply with the provisions of the Internal Revenue Code of 1986, as amended (the 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 Code.

Ohio Tax Exempt Income Fund 33

The fund is subject to the provisions of Accounting Standards Codification 740 Income Taxes (ASC 740). ASC 740 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The fund did not have a liability to record for any unrecognized tax benefits in the accompanying financial statements. 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. Each of the fund’s federal tax returns for the prior three fiscal years remains subject to examination by the Internal Revenue Service.

At May 31, 2017, the fund had a capital loss carryover of $2,485,083 available to the extent allowed by the Code to offset future net capital gain, if any. For any carryover, the amount of the carryover and that carryover’s expiration date is:


	Loss carryover

Short-term	Long-term	Total	Expiration

$788,831	$1,384,882	$2,173,713	*

97,718	N/A	97,718	May 31, 2018

213,652	N/A	213,652	May 31, 2019

^*Under the Regulated Investment Company Modernization Act of 2010, the fund will be permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. However, any losses incurred will be required to be utilized prior to the losses incurred in pre-enactment tax years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law.

Distributions to shareholders Income dividends are recorded daily by the fund and are paid monthly. Distributions from capital gains, 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/or permanent differences from the expiration of a capital loss carryover. 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. At the close of the reporting period, the fund reclassified $2,161 to increase undistributed net investment income $413,222 to decrease paid-in capital and $411,061 to decrease accumulated net realized loss.

The tax basis components of distributable earnings and the federal tax cost as of the close of the reporting period
were as follows:


Unrealized appreciation	$6,949,367

Unrealized depreciation	(317,547)

Net unrealized appreciation	6,631,820

Undistributed ordinary income	15,687

Undistributed tax-exempt income	65,998

Capital loss carryforward	(2,485,083)

Cost for federal income tax purposes	$126,927,682

Note 2: Management fee, administrative services and other transactions

The fund pays Putnam Management a management fee (based on the fund’s average net assets and computed and paid monthly) at annual rates that may vary based on the average of the aggregate net assets of all open-end mutual funds sponsored by Putnam Management (excluding net assets of funds that are invested in, or that are invested in by, other Putnam funds to the extent necessary to avoid “double counting” of those assets). Such annual rates may vary as follows:


0.590%	of the first $5 billion,	0.390%	of the next $50 billion,

0.540%	of the next $5 billion,	0.370%	of the next $50 billion,

0.490%	of the next $10 billion,	0.360%	of the next $100 billion and

0.440%	of the next $10 billion,	0.355%	of any excess thereafter.


34 Ohio Tax Exempt Income Fund

For the reporting period, the management fee represented an effective rate (excluding the impact from any expense waivers in effect) of 0.436% of the fund’s average net assets.

Putnam Management has contractually agreed, through September 30, 2018, to waive fees or reimburse the fund’s expenses to the extent necessary to limit the cumulative expenses of the fund, exclusive of brokerage, interest, taxes, investment-related expenses, extraordinary expenses, acquired fund fees and expenses and payments under the fund’s investor servicing contract, investment management contract and distribution plans, on a fiscal year-to-date basis to an annual rate of 0.20% of the fund’s average net assets over such fiscal year-to-date period. During the reporting period, the fund’s expenses were not reduced as a result of this limit.

Putnam Investments Limited (PIL), an affiliate of Putnam Management, is authorized by the Trustees to manage a separate portion of the assets of the fund as determined by Putnam Management from time to time. PIL did not manage any portion of the assets of the fund during the reporting period. If Putnam Management were to engage the services of PIL, Putnam Management would pay a quarterly sub-management fee to PIL for its services at an annual rate of 0.40% of the average net assets of the portion of the fund managed by PIL.

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 State Street. Custody fees are based on the fund’s asset level, the number of its security holdings and transaction volumes.

Putnam Investor Services, Inc., an affiliate of Putnam Management, provides investor servicing agent functions to the fund. Putnam Investor Services, Inc. received fees for investor servicing for class A, class B, class C, class M and class Y shares that included (1) a per account fee for each direct and underlying non-defined contribution account (“retail account”) of the fund; (2) a specified rate of the fund’s assets attributable to defined contribution plan accounts; and (3) a specified rate based on the average net assets in retail accounts. Putnam Investor Services, Inc. has agreed that the aggregate investor servicing fees for each fund’s retail and defined contribution accounts for these share classes will not exceed an annual rate of 0.25% of the fund’s average assets attributable to such accounts.

Prior to September 1, 2016, Putnam Investor Services, Inc. received fees for investor servicing for class A, class B, class C, class M and class Y shares that included (1) a per account fee for each retail account of the fund and each of the other funds in its specified category, which was totaled and then allocated to each fund in the category based on its average daily net assets; (2) a specified rate of the fund’s assets attributable to defined contribution plan accounts; and (3) a specified rate based on the average net assets in retail accounts. Prior to September 1, 2016, Putnam Investor Services, Inc. had agreed that the aggregate investor servicing fees for each fund’s retail and defined contribution accounts for these share classes would not exceed an annual rate of 0.320% of the fund’s average assets attributable to such accounts.

During the reporting period, the expenses for each class of shares related to investor servicing fees
were as follows:


Class A	$81,828	Class M	383

Class B	1,103	Class Y	8,952

Class C	7,988	Total	$100,254

The fund has entered into expense offset arrangements with Putnam Investor Services, Inc. and State Street whereby Putnam Investor Services, Inc.’s and State Street’s fees are reduced by credits allowed on cash balances. For the reporting period, the fund’s expenses were reduced by $6,466 under the expense offset arrangements.

Each Independent Trustee of the fund receives an annual Trustee fee, of which $102, as a quarterly retainer, has been allocated to the fund, and an additional fee for each Trustees meeting attended. Trustees also are reimbursed for expenses they incur relating to their services as Trustees.

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 and were first elected prior to 2004. Benefits under the Pension Plan are equal to 50% of the Trustee’s average annual attendance and retainer fees for

Ohio Tax Exempt Income Fund 35

the three years ended December 31, 2005. The retirement benefit is payable during a Trustee’s lifetime, beginning the year following retirement, for the number of years of service through December 31, 2006. Pension expense for the fund is included in Trustee compensation and expenses in the Statement of operations. Accrued pension liability is included in Payable for Trustee compensation and expenses in the Statement of assets and liabilities. The Trustees have terminated the Pension Plan with respect to any Trustee first elected after 2003.

The fund has adopted distribution plans (the Plans) with respect to the following share classes pursuant to Rule 12b–1 under the Investment Company Act of 1940. The purpose of the Plans is to compensate Putnam Retail Management Limited Partnership, an indirect wholly-owned subsidiary of Putnam Investments, LLC, for services provided and expenses incurred in distributing shares of the fund. The Plans provide payments by the fund to Putnam Retail Management Limited Partnership at an annual rate of up to the following amounts (“Maximum %”) of the average net assets attributable to each class. The Trustees have approved payment by the fund at the following annual rate (“Approved %”) of the average net assets attributable to each class. During the reporting period, the class-specific expenses related to distribution fees were as follows:


	Maximum %	Approved %	Amount

Class A	0.35%	*	$258,013

Class B	1.00%	0.85%	13,113

Class C	1.00%	1.00%	111,736

Class M	1.00%	0.50%	2,673

Total			$385,535

^*Equals the weighted average of (i) 0.20% on the net assets of the fund attributable to class A shares purchased and paid for prior to April 1, 2005 and (ii) 0.25% on all other net assets of the fund attributable to class A shares.

For the reporting period, Putnam Retail Management Limited Partnership, acting as underwriter, received net commissions of $13,161 and $39 from the sale of class A and class M shares, respectively, and received $291 and $27 in contingent deferred sales charges from redemptions of class B and class C shares, respectively.

A deferred sales charge of up to 1.00% is assessed on certain redemptions of class A shares. For the reporting period, Putnam Retail Management Limited Partnership, acting as underwriter, received no monies on class A redemptions

Note 3: Purchases and sales of securities

During the reporting period, the cost of purchases and the proceeds from sales, excluding short-term investments, were as follows:


	Cost of purchases	Proceeds from sales

Investments in securities (Long-term)	$20,231,441	$27,566,370

U.S. government securities (Long-term)	—	—

Total	$20,231,441	$27,566,370

The fund may purchase or sell investments from or to other Putnam funds in the ordinary course of business, which can reduce the fund’s transaction costs, at prices determined in accordance with SEC requirements and policies approved by the Trustees. During the reporting period, purchases or sales of long-term securities from or to other Putnam funds, if any, did not represent more than 5% of the fund’s total cost of purchases and/or total proceeds from sales.

Note 5: Market, credit and other risks

In the normal course of business, the fund trades financial instruments and enters into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the contracting party to the transaction to perform (credit risk). The fund may be exposed to additional credit risk that an institution or other entity with which the fund has unsettled or open transactions will default. The fund focuses a majority of its investments in the state of Ohio and may be affected by economic and political developments in that state.

Note 6: New pronouncements

In October 2016, the SEC adopted amendments to rules under the Investment Company Act of 1940 (“final rules”) intended to modernize the reporting and disclosure of information by registered investment companies. The final rules amend Regulation S-X and require funds to provide standardized, enhanced derivative disclosure in fund financial statements in a format designed for individual investors. The amendments to Regulation S-X also update the disclosures for other investments and investments in and advances to affiliates and amend the rules regarding the general form and content of fund financial statements. The compliance date for the amendments to Regulation S-X is August 1, 2017. Putnam Management has evaluated the amendments and its adoption will have no effect on the fund’s net assets or results of operations.

	Item 2. Code of Ethics:

(a) The fund's principal executive, financial and accounting officers are employees of Putnam Investment Management, LLC, the Fund's investment manager. As such they are subject to a comprehensive Code of Ethics adopted and administered by Putnam Investments which is designed to protect the interests of the firm and its clients. The Fund has adopted a Code of Ethics which incorporates the Code of Ethics of Putnam Investments with respect to all of its officers and Trustees who are employees of Putnam Investment Management, LLC. For this reason, the Fund has not adopted a separate code of ethics governing its principal executive, financial and accounting officers.


	Item 3. Audit Committee Financial Expert:

The Funds' Audit, Compliance and Distributions Committee is comprised solely of Trustees who are “independent” (as such term has been defined by the Securities and Exchange Commission (“SEC”) in regulations implementing Section 407 of the Sarbanes-Oxley Act (the “Regulations”)). The Trustees believe that each of the members of the Audit, Compliance and Distributions Committee also possess a combination of knowledge and experience with respect to financial accounting matters, as well as other attributes, that qualify them for service on the Committee. In addition, the Trustees have determined that each of Mr. Patterson, Ms. Baumann and Mr. Singh qualifies as an “audit committee financial expert” (as such term has been defined by the Regulations) based on their review of his or her pertinent experience and education. The SEC has stated, and the funds' amended and restated agreement and Declaration of Trust provides, that the designation or identification of a person as an audit committee financial expert pursuant to this Item 3 of Form N-CSR does not impose on such person any duties, obligations or liability that are greater than the duties, obligations and liability imposed on such person as a member of the Audit, Compliance and Distribution Committee and the Board of Trustees in the absence of such designation or identification.


	Item 4. Principal Accountant Fees and Services:


	The following table presents fees billed in each of the last two fiscal years for services rendered to the fund by the fund's independent auditor:


Fiscal year ended	Audit Fees	Audit-Related Fees	Tax Fees	All Other Fees


May 31, 2017	$53,035	$ —	$12,187	$ —
May 31, 2016	$45,006	$ —	$11,832	$ —


	For the fiscal years ended May 31, 2017 and May 31, 2016, the fund's independent auditor billed aggregate non-audit fees in the amounts of $364,080 and $642,268 respectively, to the fund, Putnam Management and any entity controlling, controlled by or under common control with Putnam Management that provides ongoing services to the fund.


	Audit Fees represent fees billed for the fund's last two fiscal years relating to the audit and review of the financial statements included in annual reports and registration statements, and other services that are normally provided in connection with statutory and regulatory filings or engagements.


	Audit-Related Fees represent fees billed in the fund's last two fiscal years for services traditionally performed by the fund's auditor, including accounting consultation for proposed transactions or concerning financial accounting and reporting standards and other audit or attest services not required by statute or regulation.


	Tax Fees represent fees billed in the fund's last two fiscal years for tax compliance, tax planning and tax advice services. Tax planning and tax advice services include assistance with tax audits, employee benefit plans and requests for rulings or technical advice from taxing authorities.


	Pre-Approval Policies of the Audit, Compliance and Distributions Committee. The Audit, Compliance and Distributions Committee of the Putnam funds has determined that, as a matter of policy, all work performed for the funds by the funds' independent auditors will be pre-approved by the Committee itself and thus will generally not be subject to pre-approval procedures.

The Audit, Compliance and Distributions Committee also has adopted a policy to pre-approve the engagement by Putnam Management and certain of its affiliates of the funds' independent auditors, even in circumstances where pre-approval is not required by applicable law. Any such requests by Putnam Management or certain of its affiliates are typically submitted in writing to the Committee and explain, among other things, the nature of the proposed engagement, the estimated fees, and why this work should be performed by that particular audit firm as opposed to another one. In reviewing such requests, the Committee considers, among other things, whether the provision of such services by the audit firm are compatible with the independence of the audit firm.


	The following table presents fees billed by the fund's independent auditor for services required to be approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X.


Fiscal year ended	Audit-Related Fees	Tax Fees	All Other Fees	Total Non-Audit Fees
