A Letter From the President

Dear Shareholder

As we ended the current reporting period, the financial markets were facing a
number of uncertainties. At the top of investors' minds were questions about
economic expansion, corporate earnings, interest rates and inflation, politics,
oil prices and terrorism.

After benefiting from aggressive monetary and fiscal policy stimulus, some fear
the U.S. economy has hit a "soft patch." In fact, economic expansion has slowed
somewhat in recent months, but we believe it is easing into a pace of growth
that is sustainable and healthy. The favorable economic environment has served
to benefit American corporations, which have continued to post strong earnings.
Although the most impressive results were seen earlier in the year, solid
productivity, improved revenue growth and cost discipline all point to a vital
corporate sector.

In terms of inflation and interest rates, the Federal Reserve Board (the Fed)
has signaled its confidence in the economic recovery by increasing the Federal
Funds target rate three times in the past several months, from 1% to 1.75%.
Inflation, for its part, has remained in check. Investors and economists are
focused on how quickly Fed policy will move from here, anxiously absorbing every
bit of economic data and Fed innuendo.

While any market jitters associated with the presidential election should
subside after November, the effect of oil prices is more difficult to predict.
At around $50 per barrel, the price of oil is clearly a concern. However, on an
inflation-adjusted basis and considering modern usage levels, the situation is
far from the crisis proportions we saw in the 1980s. Finally, although terrorism
and geopolitical crises are realities we are forced to live with today, history
has shown us that the financial effects of any single event tend to be
short-lived.

Amid the uncertainty, the Lehman Brothers Municipal Bond Index posted a 12-month
return of +4.60% as of September 30, 2004. Yields, although volatile, were not
dramatically changed year over year. As always, our investment professionals are
closely monitoring the markets, the economy and the overall environment in an
effort to make well-informed decisions for the portfolios they manage. For the
individual investor, the key during uncertain times is to remain focused on the
big picture. Investment success comes not from reacting to short-term
volatility, but from maintaining a long-term perspective and adhering to the
disciplines of asset allocation, diversification and rebalancing. We encourage
you to work with your financial advisor to ensure these time-tested techniques
are incorporated into your investment plan.

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,


                                        /s/ Terry K. Glenn

                                        Terry K. Glenn

A Discussion With Your Fund's Portfolio Manager

      We continued to focus on increasing the Fund's yield while also looking to
improve credit and coupon diversification, allowing the Fund flexibility to take
advantage of various market opportunities.

Describe the recent market environment relative to municipal bonds.

Despite considerable monthly volatility, long-term U.S. Treasury bond yields
ended the 12-month period little changed from year-ago levels. Tax-exempt bonds
were not as volatile as their taxable counterparts and registered modest gains
for the year.

Early in the period, U.S. Treasury bond yields declined while their prices,
which move in the opposite direction, rose. Somewhat surprisingly, this increase
in bond prices came as the U.S. economy continued to improve. However, solid job
creation remained elusive, producing a drag on consumer confidence. Against this
backdrop, investors became convinced that the Federal Reserve Board (the Fed)
would hold short-term interest rates near their historic lows. By mid-March
2004, yields on 30-year U.S. Treasury bonds had declined to 4.65%.

In early April, however, monthly employment reports began to reveal unexpectedly
large gains in job growth. Consumer confidence increased, and investors started
to anticipate that the Fed would soon be forced to raise short-term interest
rates to ward off potential inflation. Yields rose in response, with long-term
Treasury bond yields surpassing 5.50% early in June 2004.

For the rest of the period, bond yields generally fell as payroll growth began
to wane and inflation appeared negligible. Although the Fed embarked on a
tightening cycle with a 25 basis point (.25%) interest rate hike in June, it
also telegraphed its intention to continue raising interest rates at a measured
pace, removing earlier concerns about the potential for more dramatic increases.
Despite additional Fed interest rate hikes in August and September, the prospect
for a moderate tightening helped support higher bond prices, and lower yields,
for the remainder of the Fund's fiscal year.

By September 30, 2004, the 30-year Treasury bond yield stood at 4.89%,
essentially unchanged from a year earlier. The yield on the 10-year U.S.
Treasury note increased more than 15 basis points, ending the period at 4.12%.
Yields on long-term revenue bonds, as measured by the Bond Buyer Revenue Bond
Index, fell approximately 20 basis points during the past 12 months. According
to Municipal Market Data, yields on AAA-rated issues maturing in 30 years
declined 5 basis points to 4.68%, while yields on 10-year AAA-rated issues
remained essentially unchanged at 3.47%.

More than $360 billion in new long-term tax-exempt bonds was issued in the past
12 months, a drop of approximately 8% compared to the previous year. During the
third quarter of 2004, approximately $78 billion in long-term tax-exempt bonds
was issued, a decline of nearly 12% compared to the same three months in 2003.
The trend of declining municipal bond issuance allowed tax-exempt bond prices to
register moderate gains and outperform the taxable market.

Describe conditions in the State of New York.

New York maintains credit ratings of A2 from Moody's, AA from Standard & Poor's
and AA- from Fitch. Moody's recently assigned a positive outlook to the state's
credit rating, while Fitch carries a stable trend and Standard & Poor's applies
a negative outlook. New issuance of New York municipal bonds has slowed in the
past year and, year-to-date as of September 30, is down about 18% versus the
same period a year ago. The limited availability of new bonds has kept portfolio
turnover relatively muted.

The weakened economy continued to put pressure on New York's budget. Despite
spending cuts and significant increases in personal and sales tax rates, the
state relied on one-time revenue sources, particularly $4.2 billion in proceeds
from tobacco settlement revenue bonds, to close its budget gap in fiscal year
2004 (which ended March 31, 2004).

The state's 2005 fiscal year opened without an adopted budget. The governor's
executive budget totals $99 billion and recommends closing a $5 billion gap
through $2.6 billion in spending cuts and $1.5 billion in non-recurring sources,
significantly less than the prior two fiscal years. Adopting and maintaining a
balanced budget has been complicated by political resistance to additional tax
hikes and cuts in popular programs, as well as pressures from local governments
for pension and Medicaid relief, and a lack of readily available one-time
revenue sources. The proposed budget also does not address a lawsuit recently
won by the Campaign for Fiscal Equity that could require up to $2 billion in
annual state education spending.


4      MERRILL LYNCH NEW YORK MUNICIPAL BOND FUND      SEPTEMBER 30, 2004


How did the Fund perform during the fiscal year in light of the existing market
conditions?

For the 12-month period ended September 30, 2004, the Fund's Class A, Class B,
Class C and Class I Shares had total returns of +3.05%, +2.72%, +2.53% and
+3.15%, respectively. (Fund results shown do not reflect sales charges and would
be lower if sales charges were included. Complete performance information can be
found on pages 6 - 8 of this report to shareholders.) The unmanaged Lehman
Brothers Municipal Bond Index, which measures the performance of municipal bonds
throughout the nation, returned +4.60% for the same period while the Lipper New
York Municipal Debt Funds category had an average return of +3.94%. (Funds in
this Lipper category invest in securities that are exempt from New York State or
City taxes.)

In the past year, we found ourselves in an unusual market situation -- one
without historical precedent. The Fed had begun increasing interest rates, yet
longer-dated bond prices rallied as their yields declined. We had positioned the
Fund for interest rate hikes by maintaining a relatively short duration. This
normally would be a prudent approach in a rising interest rate environment, as a
shorter duration helps to limit an investment's sensitivity to rate increases
while also providing a level of protection to its underlying net asset value.
Our shorter, defensive positioning hampered performance as the market rallied
this summer, but we believe this is the appropriate posture for the anticipated
higher interest rate environment ahead. Also detracting from Fund performance
during the year was the default of the bonds of Cicero, New York. These revenue
bonds, issued to finance a recreation facility in Cicero, were sold out of the
portfolio in mid-summer.

During the year, we continued to focus on enhancing shareholder value through an
emphasis on providing attractive tax-exempt income and reducing the level of
portfolio volatility. The Fund benefited from strong couponing and a higher
accrual than many of its peers, making its yield quite favorable.

What changes were made to the portfolio during the year?

We looked to purchase bonds in the 20-year - 30-year maturity range as
compelling opportunities arose. Our observations and research revealed that the
longer end of the yield curve has held firm, while the 10-year - 15-year sector
has continued to be more volatile.

We consistently looked for opportunities to pick up yield and actively added new
credits with yields exceeding 5% whenever possible. Most recently, however, we
have seen a decline in new issuance, making it difficult to significantly
restructure the portfolio. We also sought to enhance the Fund's flexibility in
responding to the markets. Our goal is to build a more diversified portfolio
that incorporates a variety of credits and coupons. For example, we added some
discounted bonds with 4.5% coupons as well as attractive retail names in an
effort to capitalize on market opportunities not necessarily associated with
interest rate movements.

Finally, as our research turned negative on tobacco bonds, we reduced our
exposure from over 1% of net assets to less than 0.5%. While underweight in the
tobacco sector, the positions we did maintain contributed to the Fund's
above-average yield. Overall, we maintained our focus on increasing the income
provided to shareholders while seeking to mute the Fund's net asset value
volatility.

How would you characterize the Fund's position at the close of the period?

We ended the period on course for higher interest rates. That is, we maintained
a defensive position with relatively short duration vis-a-vis our benchmarks. We
expect the Fed to continue its measured program of interest rate increases,
which should force long-term bond yields higher. While the duration and
magnitude of the Fed tightening is unknown, we believe we are not yet at the end
of the cycle. For that reason, we find it prudent to maintain a defensive
stance. The benefit of this approach is that it should lessen the Fund's net
asset value volatility, while also continuing to generate an attractive yield
for our shareholders.

Finally, we expect New York municipal bond issuance to increase as the state and
its municipalities capitalize on the still low short-term interest rates to
lower their financing costs. Several large issues that had been held up pending
the required approval look to take advantage of legislation resulting from the
events of 9/11. The legislation allowed for additional refunding and provided
for certain projects that would benefit New York City rebuilding efforts. We
expect that the increased issuance should provide the Fund with more attractive
trading opportunities.

Performance Data

About Fund Performance

Investors are able to purchase shares of the Fund through multiple pricing
alternatives:

o     Class A Shares incur a maximum initial sales charge (front-end load) of 4%
      and an account maintenance fee of 0.10% per year (but no distribution
      fee).

o     Class B Shares are subject to a maximum contingent deferred sales charge
      of 4%, declining to 0% after six years. All Class B Shares purchased prior
      to December 1, 2002 will maintain the four-year schedule. In addition,
      Class B Shares are subject to a distribution fee of 0.25% per year and an
      account maintenance fee of 0.25% per year. These shares automatically
      convert to Class A Shares after approximately ten years. (There is no
      initial sales charge for automatic share conversions.)

o     Class C Shares are subject to a distribution fee of 0.35% per year and an
      account maintenance fee of 0.25% per year. In addition, Class C Shares are
      subject to a 1% contingent deferred sales charge if redeemed within one
      year of purchase.

o     Class I Shares incur a maximum initial sales charge (front-end load) of 4%
      and bear no ongoing distribution or account maintenance fees. Class I
      Shares are available only to eligible investors.

None of the past results shown should be considered a representation of future
performance. Current performance may be lower or higher than the performance
data quoted. Refer to www.mlim.ml.com to obtain performance data current to the
most recent month-end. Performance results do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. Figures shown in each of the following tables assume reinvestment of all
dividends and capital gain distributions, if any, at net asset value on the
payable date. Investment return and principal value of shares will fluctuate so
that shares, when redeemed, may be worth more or less than their original cost.
Dividends paid to each class of shares will vary because of the different levels
of account maintenance, distribution and transfer agency fees applicable to each
class, which are deducted from the income available to be paid to shareholders.
The Fund's Investment Adviser voluntarily waived a portion of its fee. Without
such waiver, the Fund's performance would have been lower.

Disclosure of Expenses

Shareholders of this Fund may incur the following charges: (a) expenses related
to transactions, including sales charges, redemption fees and exchange fees; and
(b) operating expenses, including advisory fees, distribution fees including
12(b)-1 fees, and other Fund expenses. The following example (which is based on
a hypothetical investment of $1,000 invested on April 1, 2004 and held through
September 30, 2004) is intended to assist shareholders both in calculating
expenses based on an investment in the Fund and in comparing these expenses with
similar costs of investing in other mutual funds.

The first table below provides information about actual account values and
actual expenses. In order to estimate the expenses a shareholder paid during the
period covered by this report, shareholders can divide their account value by
$1,000 and then multiply the result by the number in the first line under the
heading entitled "Expenses Paid During the Period."

The second table below provides information about hypothetical account values
and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses. In order to assist
shareholders in comparing the ongoing expenses of investing in this Fund and
other funds, compare the 5% hypothetical example with the 5% hypothetical
examples that appear in other funds' shareholder reports.

The expenses shown in the table are intended to highlight shareholders ongoing
costs only and do not reflect any transactional expenses, such as sales charges,
redemption fees, or exchange fees. Therefore, the second table is useful in
comparing ongoing expenses only, and will not help shareholders determine the
relative total expenses of owning different funds. If these transactional
expenses were included, shareholder expenses would have been higher.

*     For each class of the Fund, expenses are equal to the annualized expense
      ratio for the class (.85% for Class A, 1.26% for Class B, 1.35% for Class
      C and .75% for Class I), multiplied by the average account value over the
      period, multiplied by 183/366 (to reflect the one-half year period shown).
**    Hypothetical 5% annual return before expenses is calculated by pro-rating
      the number of days in the most recent fiscal half year divided by 366.

Notes to Financial Statements

1. Significant Accounting Policies:

Merrill Lynch New York Municipal Bond Fund (the "Fund") is part of the Merrill
Lynch Multi-State Municipal Series Trust (the "Trust"). The Fund is registered
under the Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund's financial statements are prepared in
conformity with U.S. generally accepted accounting principles, which may require
the use of management accruals and estimates. Actual results may differ from
these estimates. The Fund offers multiple classes of shares. Class A and Class I
Shares are sold with a front-end sales charge. Class B and Class C Shares may be
subject to a contingent deferred sales charge. All classes of shares have
identical voting, dividend, liquidation and other rights and the same terms and
conditions, except that Class A, Class B and Class C Shares bear certain
expenses related to the account maintenance of such shares, and Class B and
Class C Shares also bear certain expenses related to the distribution of such
shares. Each class has exclusive voting rights with respect to matters relating
to its account maintenance and distribution expenditures. Income, expenses
(other than expenses attributable to a specific class) and realized and
unrealized gains and losses are allocated daily to each class based on its
relative net assets. The following is a summary of significant accounting
policies followed by the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the last available bid price in the
over-the-counter market or on the basis of values as obtained by a pricing
service. Pricing services use valuation matrixes that incorporate both
dealer-supplied valuations and valuation models. The procedures of the pricing
service and its valuations are reviewed by the officers of the Fund under the
general direction of the Board of Trustees. Such valuations and procedures will
be reviewed periodically by the Board of Trustees of the Trust. Financial
futures contracts and options thereon, which are traded on exchanges, are valued
at their closing prices as of the close of such exchanges. Options written or
purchased are valued at the last sale price in the case of exchange-traded
options. In the case of options traded in the over-the-counter market, valuation
is the last asked price (options written) or the last bid price (options
purchased). Swap agreements are valued by quoted fair values received daily by
the Fund's pricing service. Short-term investments with a remaining maturity of
60 days or less are valued at amortized cost which approximates market value,
under which method the investment is valued at cost and any premium or discount
is amortized on a straight line basis to maturity. Investments in open-end
investment companies are valued at their net asset value each business day.
Securities and other assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
direction of the Board of Trustees of the Trust.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies both to increase the return of the Fund and to hedge, or
protect, its exposure to interest rate movements and movements in the securities
markets. Losses may arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

o     Financial futures contracts -- The Fund may purchase or sell financial
      futures contracts and options on such futures contracts. Futures contracts
      are contracts for delayed delivery of securities at a specific future date
      and at a specific price or yield. Upon entering into a contract, the Fund
      deposits and maintains as collateral such initial margin as required by
      the exchange on which the transaction is effected. Pursuant to the
      contract, the Fund agrees to receive from or pay to the broker an amount
      of cash equal to the daily fluctuation in value of the contract. Such
      receipts or payments are known as variation margin and are recorded by the
      Fund as unrealized gains or losses. 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.

o     Forward interest rate swaps -- The Fund may enter into forward interest
      rate swaps. In a forward interest rate swap, the Fund and the counterparty
      agree to make periodic net payments on a specified notional contract
      amount, commencing on a specified future effective date, unless terminated
      earlier. When the agreement is closed, the Fund records a realized gain or
      loss in an amount equal to the value of the agreement.

(c) 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.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are


22     MERRILL LYNCH NEW YORK MUNICIPAL BOND FUND      SEPTEMBER 30, 2004


Notes to Financial Statements (continued)

entered into (the trade dates). Realized gains and losses on security
transactions are determined on the identified cost basis. Dividend income is
recorded on the ex-dividend dates. Interest income is recognized on the accrual
basis. The Fund amortizes all premiums and discounts on debt securities.

(e) Prepaid registration fees -- Prepaid registration fees are charged to
expense as the related shares are issued.

(f) Dividends and distributions -- Dividends from net investment income are
declared daily and paid monthly. Distributions of capital gains are recorded on
the ex-dividend dates.

(g) 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.

(h) Reclassifications -- U.S. generally accepted accounting principles require
that certain components of net assets be adjusted to reflect permanent
differences between financial and tax reporting. Accordingly, during the current
year, $61,758 has been reclassified between undistributed net investment income
and accumulated realized capital losses as a result of permanent differences
attributable to the characterization of distributions. This reclassification has
no effect on net assets or net asset values per share.

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. The Fund has entered into a Distribution
Agreement and Distribution Plans with FAM Distributors, Inc. ("FAMD" or the
"Distributor"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc.

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: .55% of the Fund's average daily net assets not exceeding $500
million; .525% of average daily net assets in excess of $500 million but not
exceeding $1 billion; and .50% of average daily net assets in excess of $1
billion. The Investment Adviser has agreed to waive its management fee by the
amount of management fees the Fund pays to FAM indirectly through its investment
in CMA New York Municipal Money Fund. For the year ended September 30, 2004, FAM
reimbursed the Fund in the amount of $12,204.

Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule
12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor an
ongoing account maintenance fee and a distribution fee. These fees are accrued
daily and paid monthly, at the annual rates based upon the average daily net
assets of the shares as follows:

- --------------------------------------------------------------------------------
                                                     Account        Distribution
                                                 Maintenance Fee        Fee
- --------------------------------------------------------------------------------
Class A ..................................             .10%             --
Class B ..................................             .25%            .25%
Class C ..................................             .25%            .35%
- --------------------------------------------------------------------------------

Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner
& Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., also provides account
maintenance and distribution services to the Fund. The ongoing account
maintenance fee compensates the Distributor and MLPF&S for providing account
maintenance services to Class A, Class B and Class C shareholders. The ongoing
distribution fee compensates the Distributor and MLPF&S for providing
shareholder and distribution-related services to Class B and Class C
shareholders.

For the year ended September 30, 2004, FAMD earned underwriting discounts and
direct commissions and MLPF&S earned dealer concessions on the sales of the
Fund's Class A and Class I Shares as follows:

- --------------------------------------------------------------------------------
                                                     FAMD                 MLPF&S
- --------------------------------------------------------------------------------
Class A ..............................              $ 3,733              $29,039
Class I ..............................              $   137              $ 1,500
- --------------------------------------------------------------------------------

For the year ended September 30, 2004, MLPF&S received contingent deferred sales
charges of $58,101 and $5,661 relating to transactions in Class B and Class C
Shares, respectively.

Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is
the Fund's transfer agent.

For the year ended September 30, 2004, the Fund reimbursed FAM $5,943 for
certain accounting services.

5. Short-Term Borrowings:

The Fund, along with certain other funds managed by FAM and its affiliates, is a
party to a $500,000,000 credit agreement with Bank One, N.A. and certain other
lenders. The Fund may borrow under the credit agreement to fund shareholder
redemptions and for other lawful purposes other than for leverage. The Fund may
borrow up to the maximum amount allowable under the Fund's current prospectus
and statement of additional information, subject to various other legal,
regulatory or contractual limits. The Fund pays a commitment fee of .09% per
annum based on the Fund's pro rata share of the unused portion of the credit
agreement. Amounts borrowed under the credit agreement bear interest at a rate
equal to, at each fund's election, the Federal Funds rate plus .50% or a base
rate as determined by Bank One, N.A. On November 28, 2003, the credit agreement
was renewed for one year under the same terms. The Fund did not borrow under the
credit agreement during the year ended September 30, 2004.

6. Distributions to Shareholders:

The tax character of distributions paid during the fiscal years ended September
30, 2004 and September 30, 2003 was as follows:

- -------------------------------------------------------------------------------
                                                  9/30/2004          9/30/2003
- -------------------------------------------------------------------------------
Distributions paid from:
   Tax-exempt income .....................      $ 11,246,864       $ 12,145,597
   Ordinary income .......................            61,758                 --
                                                -------------------------------
Total distributions ......................      $ 11,308,622       $ 12,145,597
                                                ===============================

As of September 30, 2004, the components of accumulated losses on a tax basis
were as follows:

- -----------------------------------------------------------------------------
Undistributed tax-exempt income--net ....................         $   223,361
Undistributed long-term capital gains--net ..............                  --
                                                                  -----------
Total undistributed earnings--net .......................             223,361
Capital loss carryforward ...............................          (8,612,548)*
Unrealized gains--net ...................................           3,807,456**
                                                                  -----------
Total accumulated losses--net ...........................         $(4,581,731)
                                                                  ===========

*     On September 30, 2004, the Fund had a net capital loss carryforward of
      $8,612,548, all of which expires in 2009. This amount will be available to
      offset like amounts of any future taxable gains.
**    The difference between book-basis and tax-basis net unrealized gains is
      attributable primarily to the tax deferral of losses on wash sales, the
      tax deferral of losses on straddles, the realization for tax purposes of
      unrealized losses on certain futures contracts, the difference between
      book and tax amortization methods for premiums and discounts on fixed
      income securities and the deferral of post-October capital losses for tax
      purposes.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Trustees
of Merrill Lynch Multi-State Municipal
Series Trust:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Merrill Lynch New York Municipal Bond Fund of
Merrill Lynch Multi-State Municipal Series Trust (the "Trust") as of September
30, 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 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 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 September 30, 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
Merrill Lynch New York Municipal Bond Fund of Merrill Lynch Multi-State
Municipal Series Trust as of September 30, 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 U.S. generally accepted
accounting principles.

         (e)(1) The registrant's audit committee (the "Committee") has adopted
         policies and procedures with regard to the pre-approval of services.
         Audit, audit-related and tax compliance services provided to the
         registrant on an annual basis require specific pre-approval by the
         Committee. The Committee also must approve other non-audit services
         provided to the registrant and those non-audit services provided to the
         registrant's affiliated service providers that relate directly to the
         operations and the financial reporting of the registrant. Certain of
         these non-audit services that the Committee believes are a) consistent
         with the SEC's auditor independence rules and b) routine and recurring
         services that will not impair the independence of the independent
         accountants may be approved by the Committee without consideration on a
         specific case-by-case basis ("general pre-approval"). However, such
         services will only be deemed pre-approved provided that any individual
         project does not exceed $5,000 attributable to the registrant or
         $50,000 for all of the registrants the Committee oversees. Any proposed
         services exceeding the pre-approved cost levels will require specific
         pre-approval by the Committee, as will any other services not subject
         to general pre-approval (e.g., unanticipated but permissible services).
         The Committee is informed of each service approved subject to general
         pre-approval at the next regularly scheduled in-person board meeting.

         (h) The registrant's audit committee has considered and determined that
         the provision of non-audit services that were rendered to the
         registrant's investment adviser and any entity controlling, controlled
         by, or under common control with the investment adviser that provides
         ongoing services to the registrant that were not pre-approved pursuant
         to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible
         with maintaining the principal accountant's independence.
