CMA OHIO MUNICIPAL MONEY FUND, MARCH 31, 2004 A Letter From the President Dear Shareholder Index returns during the most recent six-month and 12-month reporting periods indicate that fixed income markets - both taxable and tax-exempt - continued to reward those investors who were willing to accept greater risk. The high yield market, as measured by the Credit Suisse First Boston High Yield Index, provided a six-month return of +8.65% and a 12-month return of +22.86% as of March 31, 2004. By comparison, the Lehman Brothers Aggregate Bond Index returned +2.98% and +5.40% and the Lehman Brothers Municipal Bond Index returned +3.12% and +5.86% for the six-month and 12-month periods ended March 31, 2004, respectively. As of March month-end, the Federal Reserve Board maintained its accommodative policy stance, pledging "patience" in raising interest rates. As a result, short-term interest rates remained at historic lows and kept the short end of the yield curve relatively flat, making it increasingly difficult to find attractive income opportunities. Market watchers continue to monitor the economic data and Federal Reserve Board language for indications of interest rate direction. Having said that, if the economy continues to grow at its recent pace, many believe it is just a matter of time before interest rates move upward. Equity markets, in the meantime, continued to provide attractive returns. For the six-month and 12-month periods ended March 31, 2004, the Standard & Poor's 500 Index returned +14.08% and +35.12%, respectively. Much of the boost came from improving economic conditions throughout the past year. Significant fiscal and monetary stimulus, including the low interest rates and tax cuts, has opened the door to consumer spending, capital spending, increases in exports and long-awaited job growth. As expected, these positive developments have led the way to improvements in corporate earnings - a positive for stock markets. The events and efforts of the past year leave us with a much stronger economy today. With all of this in mind, we believe it is time for investors to consider what can go right in 2004. We encourage you to revisit your portfolio and your asset allocation strategy to ensure you are well positioned to take advantage of the opportunities that lie ahead. Your financial advisor can help you develop a strategy designed to perform through all types of market and economic cycles. We thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to serving you in the months and years ahead. Sincerely, (Terry K. Glenn) Terry K. Glenn President and Trustee CMA OHIO MUNICIPAL MONEY FUND, MARCH 31, 2004 A Discussion With Your Fund's Portfolio Manager We sought to maintain the Fund's stake in fixed rate municipal notes while still taking advantage of favorable price swings in shorter-term variable rate demand notes when available. How did the Fund perform during the fiscal year in light of the existing market conditions? For the 12-month period ended March 31, 2004, CMA Ohio Municipal Money Fund paid shareholders a net annualized yield of .43%.* As of March 31, 2004, the Fund's seven-day yield was .39%. Throughout the period, an accommodative Federal Reserve Board continued to maintain interest rates near historically low levels. The last in a series of interest rate cuts came in June 2003, as the Federal Reserve Board looked to stimulate economic growth and ward off the potential for deflation. Although economic growth began to accelerate later in the year, concerns over weak job growth persisted in the market. Investors tried to anticipate when the Federal Reserve Board would restore interest rates to more neutral levels. The constant interest rate analysis translated into widespread volatility, which created opportunities in the fixed income markets. Under these conditions, the Fund performed well on a relative basis. Describe conditions in the State of Ohio during the period. Despite a steadily improving national economy, Ohio's recovery continued to lag over the past 12 months. The state's manufacturing sector, facing pervasive economic weakness, continued to shed jobs. Although a real turnaround remains somewhat elusive, we have seen signs of stabilization in certain sectors. For example, the weak dollar has led to increased export activity that could help manufacturers emerge from their slowdown and make some positive progress. *Based on a constant investment throughout the period, with dividends compounded daily, and reflecting a net return to the investor after all expenses. What changes were made to the portfolio during the period? As the short-term municipal yield curve remained stable, and the Federal Reserve Board seemed content to maintain short-term interest rates at historically low levels, we found little need to vary our investment strategy during the past 12 months. Throughout the period, we sought to maintain an overweight position, relative to our peers, in fixed rate municipal notes while still taking advantage of favorable price swings in shorter-term variable rate demand notes when available. How would you characterize the portfolio's position at the close of the period? At period end, we were preparing the Fund for the anticipated redemptions associated with tax season by maintaining a higher percentage of assets in variable paper, which offers us greater liquidity. In addition, we will use this period of seasonal weakness to replace maturing municipal notes while keeping the Fund's holdings in line with those of our peer group average. We continue to monitor the changing economic climate, as well as the Federal Reserve Board's reactions to gauge the potential for policy shifts. We stand ready to adjust our investment strategy in accordance with any significant developments. Finally, we will continue to maintain the credit quality of the Fund's holdings in our ongoing effort to offer our shareholders an attractive tax- exempt yield. Kevin A.

See Notes to Financial Statements. CMA OHIO MUNICIPAL MONEY FUND, MARCH 31, 2004 Notes to Financial Statements 1. Significant Accounting Policies: CMA Ohio Municipal Money Fund (the "Fund") is part of CMA Multi-State Municipal Series Trust (the "Trust"). The Fund is registered under the Investment Company Act of 1940, as amended, as a non-diversified, open-end management investment company. The Fund's financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments--Investments are valued at amortized cost, which approximates market value. For the purpose of valuation, the maturity of a variable rate demand instrument is deemed to be the demand notice payment period. In the case of a floating rate instrument, the remaining maturity is the next coupon date on which the interest rate is to be adjusted. (b) Income taxes--It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no Federal income tax provision is required. (c) Security transactions and investment income--Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Interest income (including amortization of premium and discount) is recognized on the accrual basis. (d) Prepaid registration fees--Prepaid registration fees are charged to expense as the related shares are issued. (e) Dividends and distributions to shareholders--The Fund declares dividends daily and reinvests daily such dividends (net of non- resident alien tax and backup withholding tax withheld) in additional fund shares at net asset value. Dividends are declared from the total of net investment income, excluding discounts earned other than original issue discounts. Net realized capital gains, if any, are normally distributed annually after deducting prior years' loss carryforward. The Fund may distribute capital gains more frequently than annually in order to maintain the Fund's net asset value at $1.00 per share. (f) Expenses--Certain expenses have been allocated to the individual funds in the Trust on a pro rata basis based upon the respective aggregate net asset value of each fund included in the Trust. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. FAM is responsible for the management of the Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, the Fund pays a monthly fee based upon the average daily value of the Fund's net assets, at the following annual rates: .50% of the first $500 million of average daily net assets; .425% of average daily net assets in excess of $500 million but not exceeding $1 billion; and .375% of average daily net assets in excess of $1 billion. Pursuant to the Distribution and Shareholder Servicing Plan in compliance with Rule 12b-1 under the Investment Company Act of 1940, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S") receives a distribution fee from the Fund at the end of each month at the annual rate of .125% of average daily net assets of the Fund. The distribution fee is to compensate MLPF&S financial advisors and other directly involved branch office personnel for selling shares of the Fund and for providing direct personal services to shareholders. The distribution fee is not compensation for the administrative and operational services rendered to the Fund by MLPF&S in processing share orders and administering shareholder accounts. Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is the Fund's transfer agent. For the year ended March 31, 2004, the Fund reimbursed FAM $8,959 for certain accounting services. Certain officers and/or trustees of the Fund are officers and/or directors of FAM, PSI, FDS, and/or ML & Co. CMA OHIO MUNICIPAL MONEY FUND, MARCH 31, 2004 Notes to Financial Statements (concluded) 3. Shares of Beneficial Interest: The number of shares sold, reinvested and redeemed during the years corresponds to the amounts included in the Statements of Changes in Net Assets for net proceeds from sale of shares, value of shares reinvested and cost of shares redeemed, respectively, since shares are recorded at $1.00 per share. 4. Distributions to Shareholders: The tax character of distributions paid during the fiscal years ended March 31, 2004 and March 31, 2003 was as follows: 3/31/2004 3/31/2003 Distributions paid from: Tax-exempt income $ 1,924,097 $ 4,156,316 Ordinary income -- 2,228 ------------ ------------ Total distributions $ 1,924,097 $ 4,158,544 ============ ============ As of March 31, 2004, there were no significant differences between the book and tax components of net assets. CMA OHIO MUNICIPAL MONEY FUND, MARCH 31, 2004 Independent Auditors' Report To the Shareholders and Board of Trustees of CMA Multi-State Municipal Series Trust: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of CMA Ohio Municipal Money Fund of CMA Multi-State Municipal Series Trust (the "Trust") as of March 31, 2004, and the related statement of operations for the year then ended, the statements of changes in 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. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of March 31, 2004, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of CMA Ohio Municipal Money Fund of CMA Multi- State Municipal Series Trust as of March 31, 2004, 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 its 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.
