Manager’s Letter

Fellow Shareholders

Tax-free municipal bonds produced good returns in the 6- and 12-month periods ended October 31, 2010. In both periods, longer-term and lower-quality securities fared better than shorter-term and higher-quality munis, as investors sought attractive yields from relatively safe assets. Demand for munis remained strong as investors braced for potentially higher federal tax rates in 2011. The Summit Municipal Intermediate and Summit Municipal Income Funds produced good returns in both periods, while returns for the Summit Municipal Money Market Fund were constrained by the Fed’s near 0% interest rate policy.

MARKET ENVIRONMENT

The U.S. economic recovery continues to struggle. According to the most recent estimates, gross domestic product (GDP) grew at a meager pace of 1.6% in the second quarter and 2.0% in the third. While national unemployment remains stubbornly above 9% and the housing recovery is far from robust, we currently believe the economy is likely to continue growing at a sluggish pace in the months ahead. Encouraging signs include continued growth in industrial production, modest expansion of payrolls, and rising capital goods shipments.

Over the year, Fed officials kept the fed funds target rate in the 0.00% to 0.25% range established in late 2008. In August, the central bank adopted a policy of reinvesting principal payments from agency debt and agency mortgage-backed securities on its balance sheet into Treasury securities. Since then, the Federal Reserve embarked on a new plan to stimulate the economy by buying $600 billion worth of Treasury bonds through mid-2011, in addition to the estimated $250 billion to $300 billion previously announced. The programs are designed to lower consumer loan rates, including mortgage rates, in an effort to entice consumers to reenter the housing market. Afterward, longer-term Treasury yields tumbled to levels not seen since the depth of the financial crisis in late 2008. Intermediate- and longer-term municipal yields also declined, but not as much as Treasury interest rates.

With municipal yields at reasonable levels relative to Treasuries, tax-free securities are an attractive alternative to taxable bonds, particularly for investors in the highest tax brackets. For example, as of October 31, 2010, the 3.86% yield offered by a 30-year tax-free municipal bond rated AAA was about 97% of the 3.98% pretax yield offered by a 30-year Treasury. An investor in the 28% federal tax bracket would need to invest in a taxable bond yielding about 5.36% in order to receive the same after-tax income. Nonetheless, as in many other fixed income markets, municipal yields are at or near historic lows across the curve. (To calculate a municipal bond’s taxable-equivalent yield, divide the municipal bond’s yield by the quantity of 1.00 minus your federal tax bracket expressed as a decimal—in this case, 1.00 – 0.28, or 0.72.)

MUNICIPAL MARKET NEWS

Year-to-date municipal bond supply through October totaled more than $340 billion, according to The Bond Buyer. New supply this year reflects a steady pace of municipal borrowings for ongoing capital needs. Investor demand has been strong for most of 2010, bolstered by concerns about higher taxes. However, cash flows into municipal bond funds, while still historically high, have trailed off recently as low absolute yields deterred investors. About one-fourth of this year’s new supply represented taxable municipal issuance under the Build America Bond (BAB) program, which reduces supply of new tax-exempt securities. While we expect this year’s overall issuance to be in line with that of recent years, aggregate new tax-exempt issuance in 2010 will be somewhat lower than in 2009 because of the BAB program.

Many states continue to face fiscal difficulties and have been forced to raise taxes and fees and cut spending to close budget deficits. Despite the increasing negative press regarding their fiscal health, we do not see a near-term threat to the states’ ability to continue servicing their outstanding debts—although we have longer-term concerns about potentially onerous future pension obligations and other retirement benefits. In any event, the fiscal woes of state governments do not necessarily limit our tax-free investment opportunities. There are thousands of unique municipal issuers in a variety of sectors, many of which have good credit profiles.

Most sectors produced good returns in our 6- and 12-month reporting periods. Health care-related bonds, especially life-care issues, were among the top-performing segments. We remain cautious on health care, in part because the reform legislation passed earlier this year will lead to tighter reimbursement policies, and state budget cuts could affect Medicaid payments to providers. However, we believe the sector offers attractive investment opportunities with reasonable credit risks. Industrial revenue and pollution control revenue bonds also did well, as these credits tend to be linked to the sentiment surrounding the companies backing them. Tobacco bonds produced strong gains, but we are underweighting this sector because fundamentals are poor, and longer-term tobacco consumption trends do not appear to be especially positive. Prerefunded and escrowed-to-maturity bonds backed by Treasuries produced mild gains.

PORTFOLIO REVIEW

Summit Municipal Money Market Fund
Your fund returned 0.01% during both the 6- and 12-month periods ended October 31, 2010, compared with 0.01% for the Lipper average during the past six months and 0.03% over the fund’s fiscal year. In its November 3 statement, the Federal Open Market Committee affirmed its continuing commitment to maintaining exceptionally low levels of the federal funds rate for an extended period” and said it will seek to “maintain the target range for the federal funds rate” at 0.00% to 0.25%. With the Fed also announcing its intent to begin another round of quantitative easing, it appears unlikely that money market rates will move significantly until some time in 2012. The Fed’s policy stance means that money market investors will continue to see near 0.00% returns for some time to come.

As the market has gradually come to terms with the idea that this extraordinary period of low interest rates might be with us much longer than originally anticipated, money market rates continued to compress toward the Fed’s target. Yields on ultra-safe U.S. Treasury bills have moved dramatically lower; 90-day bills currently yield 0.10%, the six-month bill ended the period at 0.15%, while the one-year bill fell 19 basis points (100 basis points equal 1.00%) to end at 0.23%. The benchmark Libor curve, against which most commercial paper and certificates of deposit are priced, moved lower as well; the 90-day Libor ended the period at 0.29%, down six basis points since our last report, while the longer end of the curve fell even more. Municipal rates remained relatively attractive compared with taxable markets; 7-day variable rates averaged 0.27%, though six-month and one-year yields continued to fall, ending at 0.28% and 0.36%, respectively.

The fund’s strategy remains relatively unchanged since our last report. With the Fed on hold, we maintained a weighted average maturity somewhat longer than that of our peer group. The headlines remind us daily that the finances of state and local governments remain challenged, while the financials sector still has many obstacles to overcome. Thus, our focus remains on finding the highest-quality municipal borrowers and sound financing structures. With longer rates in our market continuing to offer little pickup in yield over shorter maturities, we have increased our holdings in commercial paper and notes, which fall in the three- to six-month range. Our weighted average maturity is somewhat longer than six months ago, ending the period at 47 days.

The short-term markets in which we invest are changing significantly as a result of the financial crisis and new regulations such as the upcoming Basel III accords. These changes are making short-term funding less attractive to many issuers, while at the same time the slow economy diminishes the credit quality of many borrowers. For now, supply and demand in the short-term markets remain in balance, but we remain concerned about further drops in variable rate supply, as issuers are either unable or unwilling to access this market. With all rates remaining near 0.00%, we remain focused on maintaining a high-quality, highly liquid portfolio.

Summit Municipal Intermediate Fund
Your fund returned 3.39% during the six months ended October 31, 2010, and 6.60% for the fund’s full fiscal year compared with respective returns of 3.49% and 6.69% for the Lipper Intermediate Municipal Debt Funds Average, which measures the performance of similarly managed funds. During the period, the fund’s net asset value per share rose from $11.29 to $11.48, while the 30-day SEC yield declined from 2.59% to 2.23% as bond prices rose (bond prices and yields move counter to each other).

The same pattern that prevailed during the first six months of the fund’s fiscal year carried over during the past six months. We continued to invest in various revenue sectors while reducing our exposure to general obligation (GO) and prerefunded debt. The yields provided by revenue sectors continued to be appealing, and their revenue streams are more predictable than tax-backed GO securities. We favored hospital and airport revenue bonds, increasing our exposure to the latter from 3% to about 13% of net assets, while hospitals rose a notch to 12%.

Cash flow into the fund has been strong, so we added new revenue bond issuers to keep up with demand while trimming back a bit elsewhere. The relatively high yields in the revenue sectors are due primarily to the large amount of new issuance. We favored revenue bonds of issuers with strong management teams and predictable income streams, while we remain leery of many GO credits because of ongoing budget deficits, which are likely to continue for the rest of the year and possibly beyond. In the past, we have typically increased our exposure to state GO securities as the economy emerged from a recession. This time, however, we are uncertain about the ability of an improving economy to lift states out of their financial predicaments.

We maintained the “barbell” structure adopted earlier in the year, with heavier exposure to short-term and 15-year bonds, and an underweight in three- to seven-year securities, which hurt our relative performance to some degree. We continued the barbell strategy primarily because heavy cash flows into intermediate-term bonds have driven their yields significantly lower. The yields on longer-term securities were quite a bit higher, making them far more attractive. Therefore, the combination of short- and longer-term bonds produces a better yield for the portfolio, and we believe it will provide some downside protection when interest rates eventually begin to go up.

Our security selection was also a slight negative; our holdings did well, but not as well as others we might have purchased since we preferred to maintain a more defensive profile, which protects investors in a down market. After the end of the period, Standard & Poor’s downgraded tobacco bonds as a group, but our holdings in the portfolio were not adversely affected. Our duration management (duration is a measure of a bond fund’s sensitivity to changes in interest rates) and sector allocations aided fund performance. Our duration, which ended the period at 4.3 years, was slightly long relative to similar funds, and our revenue bond allocations added to performance.

Summit Municipal Income Fund
During the 6- and 12-month periods ended October 31, 2010, your fund returned 4.25% and 8.70%, respectively, compared with 3.80% and 7.64% for the Lipper General Municipal Debt Funds Average. The fund’s net asset value rose from $11.07 to $11.30 during the past six months, while its 30-day SEC yield fell from 3.92% to 3.56%. The fund’s long-term results relative to its Lipper peer group average are favorable.

Our investment strategy hasn’t changed since our last report; we maintained a bias toward longer maturities as the steep yield curve made longer-term rates much more compelling. Most of our new purchases were in longer-term bonds, predominantly those in the 20- to 30-year maturity range. Relative to the Barclays Capital Municipal Bond Index, the fund is overweight maturities beyond 22 years and underweight in 3- to 15-year securities. This strategy benefited fund performance, since long-dated bonds outperformed shorter bonds by a fairly wide margin.

The portfolio’s weighted average maturity extended from 17.1 to 17.9 years, reflecting our investment strategy. Despite that extension, the fund’s duration (a measure of a bond fund’s sensitivity to changes in interest rates) remained fairly stable at 6.0 years as interest rates moved lower and more holdings priced to their call dates. We made minimal shifts in the fund’s quality diversification. Our exposure to AAA rated securities declined slightly, while our allocation of AA bonds rose by two percentage points. Exposure to all other ratings categories was unchanged. Shifts in portfolio diversification were also minimal. Overall, the fund’s structure reflects our investment bias for revenue bonds, as we continued to underweight the GO sector. Many states and localities are still under duress due to budget deficits, and our credit outlook calls for these pressures to persist.

Transportation is the fund’s largest sector holding, and our allocation moved slightly higher to 26%. Health care also occupied a significant presence in the portfolio. After thorough credit analysis, we selectively chose bonds that offered value, in our view. New additions to the fund included Port of Seattle, Massachusetts Department of Transportation Highway System, and South Dakota Regional Health, to name a few. (Please refer to the portfolio of investments for a detailed list of holdings and the amount each represents in the portfolio.)

Our high-quality bonds with maturities shorter than five years underperformed throughout the year, while lower-quality, longer-duration bonds fared exceptionally well. The one-year return for BBB rated securities in the Barclays index was 10.40%, while the return for AAA rated securities was much lower at 4.66%. The fund’s top performers were typically A and lower-rated securities, as well as nonrated holdings. Other major sectors with outsized returns included industrial development revenue/pollution control revenue and health care.

OUTLOOK

The current credit and economic environment for municipalities is the most challenging since the Great Depression and could remain so for some time. Ongoing economic sluggishness, the housing market downturn, and high unemployment have reduced the tax revenues collected by state and local governments, and municipal bond defaults, which have historically been rare, could increase moderately. Maintaining balanced budgets requires careful and dedicated work by state and local officials. Many issuers are trying to make the difficult but necessary fiscal decisions as they adjust to high unemployment, slow economic growth, lower tax revenues, and other tough conditions. These efforts will need to continue, with or without additional federal government assistance.

We still believe that municipals remain a high-quality market and that many longer-term securities offer good value, especially considering that tax rates are likely to rise in the next few years. Longer-term and lower-rated investment-grade bond valuations, though they have rebounded significantly from the lows of 2008, remain attractive and could improve further. In contrast, short- and intermediate-term securities appear to be fully valued and could be vulnerable if shorter-term interest rates increase, although that does not appear likely as long as inflation is low and the economy remains weak. Increased demand for munis due to higher anticipated tax rates and other factors, along with reduced tax-exempt issuance, should help cushion the effect of rising Treasury rates on the municipal market.

We believe T. Rowe Price’s strong credit research capabilities have been and will remain an asset for our investors. We continue to conduct our own thorough research and assign our own independent credit ratings before making investment decisions. As always, we are on the lookout for attractively valued bonds issued by municipalities with good fundamentals—an investment strategy that has served shareholders well in the past.

Thank you for investing with T. Rowe Price.

RISKS OF INVESTING IN MUNICIPAL SECURITIES

Funds that invest in municipal securities are subject to price declines due to rising interest rates, with long-term securities generally most sensitive to rate fluctuations. Other risks include credit rating downgrades, defaults on scheduled interest and principal payments, and the possibility that municipal securities will, because of legislation or a significant restructuring of federal income tax rates, lose their advantage as a source of tax-free income. Some income may be subject to state and local taxes and the federal alternative minimum tax (AMT).

RISKS OF INVESTING IN MONEY MARKET SECURITIES

Since money market funds are managed to maintain a constant $1.00 share price, they should have little risk of principal loss. However, there is no assurance the fund will avoid principal losses if fund holdings default or are downgraded or interest rates rise sharply in an unusually short period. In addition, the fund’s yield will vary; it is not fixed for a specific period like the yield on a bank certificate of deposit. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. Although a money market fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in it.

GLOSSARY

Barclays Capital Intermediate Competitive (1-17 Yr. Maturity) Bond Index: A subindex of the Barclays Capital Municipal Bond Index. It is a rules-based, market value-weighted index of bonds with maturities of one year to 16 years and 11 months engineered for the tax-exempt bond market.

Barclays Capital Municipal Bond Index: An unmanaged index that tracks municipal debt instruments.

Duration: The average time (expressed in years) needed for an investor to receive the present value of the future cash flows on a fixed income investment. It is used to measure a bond or bond fund’s sensitivity to interest rate changes. For example, a fund with a five-year duration would fall about 5% in price in response to a one-percentage-point increase in interest rates, and vice versa.

Fed funds target rate: An overnight lending rate set by the Federal Reserve and used by banks to meet reserve requirements. Banks also use the fed funds rate as a benchmark for their prime lending rates.

Inflation: A sustained increase in prices throughout the economy.

Libor: The London Interbank Offered Rate is a taxable money market benchmark.

Lipper averages: The averages of available mutual fund performance returns for specified time periods in defined categories by Lipper.

SEC yield (7-day simple): A method of calculating a money fund’s yield by annualizing the fund’s net investment income for the last 7 days of each period divided by the fund’s net asset value at the end of the period. Yield will vary and is not guaranteed.

SEC yield (30-day): A method of calculating a fund’s yield that assumes all portfolio securities are held until maturity. Yield will vary and is not guaranteed.

Weighted average maturity: In general, the longer the average maturity, the greater the fund’s sensitivity to interest rate changes. The weighted average maturity may take into account the interest rate readjustment dates for certain securities. Money funds must maintain a weighted average maturity of less than 60 days.

Yield curve: A graphic depiction of the relationship between yields and maturity dates for a set of similar securities, such as Treasuries or municipal securities. Yield curves typically slope upward, indicating that longer maturities offer higher yields. When the yield curve is flat, there is little or no difference between the yields offered by shorter- and longer-term securities.

Performance and Expenses

FUND EXPENSE EXAMPLE 

As a mutual fund shareholder, you may incur two types of costs: (1) transaction costs, such as redemption fees or sales loads, and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other fund expenses. The following example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the most recent six-month period and held for the entire period.

Actual Expenses
The first line of the following table (“Actual”) provides information about actual account values and expenses based on the fund’s actual returns. You may use the information in this line, together with your account balance, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes
The information on the second line of the table (“Hypothetical”) is based on hypothetical account values and expenses derived from the fund’s actual expense ratio and an assumed 5% per year rate of return before expenses (not the fund’s actual return). You may compare the ongoing costs of investing in the fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Note: T. Rowe Price charges an annual small-account maintenance fee of $10, generally for accounts with less than $2,000 ($500 for UGMA/UTMA). The fee is waived for any investor whose T. Rowe Price mutual fund accounts total $25,000 or more, accounts employing automatic investing, and IRAs and other retirement plan accounts that utilize a prototype plan sponsored by T. Rowe Price (although a separate custodial or administrative fee may apply to such accounts). This fee is not included in the accompanying table. If you are subject to the fee, keep it in mind when you are estimating the ongoing expenses of investing in the fund and when comparing the expenses of this fund with other funds.

You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs, such as redemption fees or sales loads. Therefore, the second line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. To the extent a fund charges transaction costs, however, the total cost of owning that fund is higher.

NOTES TO FINANCIAL STATEMENTS 

T. Rowe Price Summit Municipal Funds, Inc. (the corporation), is registered under the Investment Company Act of 1940 (the 1940 Act). The Summit Municipal Income Fund (the fund), a diversified, open-end management investment company, is one portfolio established by the corporation. The fund commenced operations on October 29, 1993. The fund seeks a high level of income exempt from federal income taxes.

NOTE1 - SIGNIFICANTACCOUNTING POLICIES

Basisof PreparationThe accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), which require the use of estimates made by fund management. Fund management believes that estimates and valuations are appropriate; however, actual results may differ from those estimates, and the valuations reflected in the accompanying financial statements may differ from the value ultimately realized upon sale of securities.

InvestmentTransactions,InvestmentIncome,andDistributions Income and expenses are recorded on the accrual basis. Premiums and discounts on debt securities are amortized for financial reporting purposes. Income tax-related interest and penalties, if incurred, would be recorded as income tax expense. Investment transactions are accounted for on the trade date. Realized gains and losses are reported on the identified cost basis. Distributions to shareholders are recorded on the ex-dividend date. Income distributions are declared daily and paid monthly. Capital gain distributions, if any, are generally declared and paid by the fund annually.

NewAccounting Pronouncements On May 1, 2010, the fund adopted new accounting guidance that requires enhanced disclosures about fair value measurements in the financial statements. Adoption of this guidance had no impact on the fund’s net assets or results of operations.

NOTE2 - VALUATION

The fund’s financial instruments are reported at fair value as defined by GAAP. The fund determines the values of its assets and liabilities and computes net asset value per share at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day that the NYSE is open for business.

ValuationMethods Debt securities are generally traded in the over-the-counter (OTC) market. Securities with remaining maturities of one year or more at the time of acquisition are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service, which considers the yield or price of bonds of comparable quality, coupon, maturity, and type, as well as prices quoted by dealers who make markets in such securities. Securities with remaining maturities of less than one year at the time of acquisition generally use amortized cost in local currency to approximate fair value. However, if amortized cost is deemed not to reflect fair value or the fund holds a significant amount of such securities with remaining maturities of more than 60 days, the securities are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service.

Other investments, including restricted securities, and those financial instruments for which the above valuation procedures are inappropriate or are deemed not to reflect fair value are stated at fair value as determined in good faith by the T. Rowe Price Valuation Committee, established by the fund’s Board of Directors.

ValuationInputs Various inputs are used to determine the value of the fund’s financial instruments. These inputs are summarized in the three broad levels listed below:

Level 1 – quoted prices in active markets for identical financial instruments

Level 2 – observable inputs other than Level 1 quoted prices (including, but not limited to, quoted prices for similar financial instruments, interest rates, prepayment speeds, and credit risk)

Level 3 – unobservable inputs

Observable inputs are those based on market data obtained from sources independent of the fund, and unobservable inputs reflect the fund’s own assumptions based on the best information available. The input levels are not necessarily an indication of the risk or liquidity associated with financial instruments at that level. On October 31, 2010, all of the fund’s financial instruments were classified as Level 2, based on the inputs used to determine their values.

NOTE3 - DERIVATIVEINSTRUMENTS

During the year ended October 31, 2010, the fund invested in derivative instruments. As defined by GAAP, a derivative is a financial instrument whose value is derived from an underlying security price, foreign exchange rate, interest rate, index of prices or rates, or other variable; it requires little or no initial investment and permits or requires net settlement. The fund invests in derivatives only if the expected risks and rewards are consistent with its investment objectives, policies, and overall risk profile, as described in its prospectus and Statement of Additional Information. The fund may use derivatives for a variety of purposes, such as seeking to hedge against declines in principal value, increase yield, invest in an asset with greater efficiency and at a lower cost than is possible through direct investment, or to adjust portfolio duration and credit exposure. The risks associated with the use of derivatives are different from, and potentially much greater than, the risks associated with investing directly in the instruments on which the derivatives are based. Investments in derivatives can magnify returns positively or negatively; however, the fund at all times maintains sufficient cash reserves, liquid assets, or other SEC-permitted asset types to cover the settlement obligations under its open derivative contracts.

The fund values its derivatives at fair value, as described below and in Note 2, and recognizes changes in fair value currently in its results of operations. Accordingly, the fund does not follow hedge accounting, even for derivatives employed as economic hedges. The fund does not offset the fair value of derivative instruments against the right to reclaim or obligation to return collateral. As of October 31, 2010, the fund held no derivative instruments.

Additionally, during the year ended October 31, 2010, the fund recognized $11,000 of realized gain on Futures and a $79,000 change in unrealized gain on Futures related to its investments in interest rate derivatives; such amounts are included on the accompanying Statement of Operations.

Counterparty risk related to exchange-traded derivatives, including futures and options contracts, is minimal because the exchange’s clearinghouse provides protection against defaults. Additionally, for exchange-traded derivatives, each broker, in its sole discretion, may change margin requirements applicable to the fund.

FuturesContractsThe fund is subject to interest rate risk in the normal course of pursuing its investment objectives and uses futures contracts to help manage such risk. The fund may enter into futures contracts to manage exposure to interest rate and yield curve movements, security prices, foreign currencies, credit quality, and mortgage prepayments; as an efficient means of adjusting exposure to all or part of a target market; to enhance income; as a cash management tool; and/or to adjust portfolio duration and credit exposure. A futures contract provides for the future sale by one party and purchase by another of a specified amount of a particular underlying financial instrument at an agreed-upon price, date, time, and place. The fund currently invests only in exchange-traded futures, which generally are standardized as to maturity date, underlying financial instrument, and other contract terms. Upon entering into a futures contract, the fund is required to deposit with the broker cash or securities in an amount equal to a certain percentage of the contract value (initial margin deposit); the margin deposit must then be maintained at the established level over the life of the contract. Subsequent payments are made or received by the fund each day to settle daily fluctuations in the value of the contract (variation margin), which reflect changes in the value of the underlying financial instrument. Variation margin is recorded as unrealized gain or loss until the contract is closed. The value of a futures contract included in net assets is the amount of unsettled variation margin; net variation margin receivable is reflected as an asset, and net variation margin payable is reflected as a liability on the accompanying Statement of Assets and Liabilities. Risks related to the use of futures contracts include possible illiquidity of the futures markets, contract prices that can be highly volatile and imperfectly correlated to movements in hedged security values and/or interest rates, and potential losses in excess of the fund’s initial investment. During the year ended October 31, 2010, the trust’s exposure to futures, based on underlying notional amounts, was generally less than 1% of net assets.

NOTE4 - OTHERINVESTMENTTRANSACTIONS

Consistent with its investment objective, the fund engages in the following practices to manage exposure to certain risks and/or to enhance performance. The investment objective, policies, program, and risk factors of the fund are described more fully in the fund’s prospectus and Statement of Additional Information.

Noninvestment-GradeDebtSecurities At October 31, 2010, approximately 10% of the fund’s net assets were invested, either directly or through its investment in T. Rowe Price institutional funds, in noninvestment-grade debt securities, commonly referred to as “high yield” or “junk” bonds. The noninvestment-grade bond market may experience sudden and sharp price swings due to a variety of factors, including changes in economic forecasts, stock market activity, large sustained sales by major investors, a high-profile default, or a change in the market’s psychology. These events may decrease the ability of issuers to make principal and interest payments and adversely affect the liquidity or value, or both, of such securities.

RestrictedSecurities The fund may invest in securities that are subject to legal or contractual restrictions on resale. Prompt sale of such securities at an acceptable price may be difficult and may involve substantial delays and additional costs.

Residual-Interest Bonds During the year ended October 31, 2010, the fund held residual-interest bonds (RIBs) purchased from third-party special purpose trusts, which securitize an underlying bond into RIBs and short-term floating rate bonds. RIBs generally are entitled to the cash flows of the underlying bond that remain after payment of amounts due to the floating rate bondholders and trust-related fees; they also generally have the right to acquire the underlying bond from the trust. RIBs can only be traded in accordance with Rule 144A of the Securities Act of 1933 and cannot be offered for public resale. Risks arise from changes in interest rates and the value of the underlying bond, and the sale of the RIBs may involve delay or additional costs.

Other Purchases and sales of portfolio securities other than short-term securities aggregated $182,770,000 and $55,997,000, respectively, for the year ended October 31, 2010.

NOTE5 - FEDERALINCOMETAXES

No provision for federal income taxes is required since the fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code and distribute to shareholders all of its income and gains. Distributions determined in accordance with federal income tax regulations may differ in amount or character from net investment income and realized gains for financial reporting purposes. Financial reporting records are adjusted for permanent book/tax differences to reflect tax character but are not adjusted for temporary differences.

The fund files U.S. federal, state, and local tax returns as required. The fund’s tax returns are subject to examination by the relevant tax authorities until expiration of the applicable statute of limitations, which is generally three years after filing of the tax return, but which can be extended to six years in certain circumstances. Tax returns for open years have incorporated no uncertain tax positions that require a provision for income taxes.

Reclassifications to paid-in capital relate primarily to a tax practice that treats a portion of the proceeds from each redemption of capital shares as a distribution of taxable net investment income and/or realized capital gain and undistributed income on which the fund paid tax. Reclassifications between income and gain relate primarily to differences between book/tax amortization policies. For the year ended October 31, 2010, the following reclassifications were recorded to reflect tax character; there was no impact on results of operations or net assets:

Distributions during the years ended October 31, 2010 and October 31, 2009, totaled $20,538,000 and $16,363,000, respectively, and were characterized as tax-exempt for tax purposes. At October 31, 2010, the tax-basis cost of investments and components of net assets were as follows:

The fund intends to retain realized gains to the extent of available capital loss carryforwards. During the year ended October 31, 2010, the fund utilized $1,114,000 of capital loss carryforwards. The fund’s unused capital loss carryforwards as of October 31, 2010, expire: $297,000 in fiscal 2015, $4,456,000 in fiscal 2016, and $2,106,000 in fiscal 2017.

NOTE6 - RELATED PARTYTRANSACTIONS

The fund is managed by T. Rowe Price Associates, Inc. (the manager or Price Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. The investment management and administrative agreement between the fund and the manager provides for an all-inclusive annual fee equal to 0.50% of the fund’s average daily net assets. The fee is computed daily and paid monthly. The agreement provides that investment management, shareholder servicing, transfer agency, accounting, custody services, and directors’ fees and expenses are provided to the fund, and interest, taxes, brokerage commissions, and extraordinary expenses are paid directly by the fund.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Tothe BoardofDirectorsofT.Rowe PriceSummitMunicipalFunds,Inc.and ShareholdersofT.Rowe PriceSummitMunicipalIncomeFund

In our opinion, the accompanying statement of assets and liabilities, including the portfolio of investments, 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 T. Rowe Price Summit Municipal Income Fund (one of the portfolios comprising T. Rowe Price Summit Municipal Funds, Inc., hereafter referred to as the “Fund”) at October 31, 2010, 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. We believe that our audits, which included confirmation of securities at October 31, 2010 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

Item 2. Code of Ethics.

The registrant has adopted a code of ethics, as defined in Item 2 of Form N-CSR, applicable to its principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of this code of ethics is filed as an exhibit to this Form N-CSR. No substantive amendments were approved or waivers were granted to this code of ethics during the period covered by this report.

Item 3. Audit Committee Financial Expert.

The registrant’s Board of Directors/Trustees has determined that Mr. Anthony W. Deering qualifies as an audit committee financial expert, as defined in Item 3 of Form N-CSR. Mr. Deeering is considered independent for purposes of Item 3 of Form N-CSR.

Item 4. Principal Accountant Fees and Services.

(a) – (d) Aggregate fees billed to the registrant for the last two fiscal years for professional services rendered by the registrant’s principal accountant were as follows:

Audit fees include amounts related to the audit of the registrant’s annual financial statements and services normally provided by the accountant in connection with statutory and regulatory filings. Audit-related fees include amounts reasonably related to the performance of the audit of the registrant’s financial statements and specifically include the issuance of a report on internal controls and, if applicable, agreed-upon procedures related to fund acquisitions. Tax fees include amounts related to services for tax compliance, tax planning, and tax advice. The nature of these services specifically includes the review of distribution calculations and the preparation of Federal, state, and excise tax returns. All other fees include the registrant’s pro-rata share of amounts for agreed-upon procedures in conjunction with service contract approvals by the registrant’s Board of Directors/Trustees.

(e)(1) The registrant’s audit committee has adopted a policy whereby audit and non-audit services performed by the registrant’s principal accountant for the registrant, its investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant require pre-approval in advance at regularly scheduled audit committee meetings. If such a service is required between regularly scheduled audit committee meetings, pre-approval may be authorized by one audit committee member with ratification at the next scheduled audit committee meeting. Waiver of pre-approval for audit or non-audit services requiring fees of a de minimis amount is not permitted.

    (2) No services included in (b) – (d) above were approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Less than 50 percent of the hours expended on the principal accountant’s engagement to audit the registrant’s financial statements for the most recent fiscal year were attributed to work performed by persons other than the principal accountant’s full-time, permanent employees.

(g) The aggregate fees billed for the most recent fiscal year and the preceding fiscal year by the registrant’s principal accountant for non-audit services rendered to the registrant, its investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant were $1,429,000 and $2,179,000, respectively.

(h) All non-audit services rendered in (g) above were pre-approved by the registrant’s audit committee. Accordingly, these services were considered by the registrant’s audit committee in maintaining the principal accountant’s independence.

EX-99.CODE ETH

CODE OF ETHICS FOR PRINCIPAL EXECUTIVE AND SENIOR FINANCIAL     

OFFICERS OF THE PRICE FUNDS     

UNDER THE SARBANES-OXLEY ACT OF 2002     

I. General Statement. This Code of Ethics (the “Price Funds S-O Code”) has been designed 

to bring the Price Funds into compliance with the applicable requirements of the Sarbanes-Oxley 

Act of 2002 (the “Act”) rules promulgated by The Securities and Exchange Commission 

thereunder (“Regulations”). The Price Funds S-O Code applies solely to the Principal 

Executive Officer, Principal Financial Officer, Principal Accounting Officer or Controller of, or 

persons performing similar functions for, a Price Fund (whether such persons are employed by a 

Price Fund or third party) (“Covered Officers”). The “Price Funds” shall include each mutual 

fund that is managed, sponsored and distributed by affiliates of T. Rowe Price Group, Inc. 

(“Group”). The investment managers to the Price Funds will be referred to as the “Price Fund 

Advisers.” A list of Covered Officers is attached as Exhibit A. 

The Price Fund Advisers have, along with their parent, T. Rowe Price Group, Inc. (“Group”) 

also maintained a comprehensive Code of Ethics and Conduct (the “Group Code”) since 1972, 

which applies to all officers, directors and employees of the Price Funds, Group and its affiliates. 

As mandated by the Act, Group has adopted a Code (the “Group S-O Code”), similar to the 

Price Funds S-O Code, which applies solely to its principal executive and senior financial 

officers. The Group S-O Code and the Price Funds S-O Code will be referred to collectively as 

the “S-O Codes”. 

The Price Funds S-O Code has been adopted by the Price Funds in accordance with the Act and 

Regulations thereunder and will be administered in conformity with the disclosure requirements 

of Item 2 of Form N-CSR. The S-O Codes are attachments to the Group Code. In many respects 

the S-O Codes are supplementary to the Group Code, but the Group Code is administered 

separately from the S-O Codes, as the S-O Codes are from each other. 

II. Purpose of the Price Funds S-O Code. The purpose of the Price Funds S-O Code, as 

mandated by the Act and the Regulations, is to establish standards that are reasonably designed 

to deter wrongdoing and to promote: 

             Ethical Conduct. Honest and ethical conduct, including the ethical handling of actual or 

             apparent conflicts of interest between personal and professional relationships. 

             Disclosure. Full, fair, accurate, timely and understandable disclosure in reports and 

             documents that the Price Funds file with, or submit to, the SEC and in other public 

             communications made by the Price Funds. 

             Compliance. Compliance with applicable governmental laws, rules and regulations. 

             Reporting of Violations. The prompt internal reporting of violations of the Price Funds 

             S-O Code to an appropriate person or persons identified in the Price Funds S-O Code. 

             Accountability. Accountability for adherence to the Price Funds S-O Code. 

III. Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest. 

Overview. Each Covered Officer owes a duty to the Price Funds to adhere to a high standard of 

honesty and business ethics and should be sensitive to situations that may give rise to actual as 

well as apparent conflicts of interest. 

A “conflict of interest” occurs when a Covered Officer’s private interest interferes with the 

interests of, or his or her service to, the Price Funds. For example, a conflict of interest would 

arise if a Covered Officer, or a member of his or her family, receives improper personal benefits 

as a result of his or her position with a Price Fund. 

Certain conflicts of interest covered by the Price Funds S-O Code arise out of the relationships 

between Covered Officers and the Price Funds and may already be subject to provisions 

regulating conflicts of interest in the Investment Company Act of 1940 (“Investment Company 

Act”), the Investment Advisers Act of 1940 (“Investment Advisers Act”) and the Group Code. 

For example, Covered Officers may not individually engage in certain transactions (such as the 

purchase or sale of securities or other property) with a Price Fund because of their status as 

“affiliated persons” of a Price Fund. The compliance programs and procedures of the Price 

Funds and Price Fund Advisers are designed to prevent, or identify and correct, violations of 

these provisions. 

Although typically not presenting an opportunity for improper personal benefit, conflicts arise 

from, or as a result of, the contractual relationship between a Price Fund and its Price Fund 

Adviser (and its affiliates) of which the Covered Officers may also be officers or employees. As 

a result, the Price Funds S-O Code recognizes that the Covered Officers will, in the normal 

course of their duties (whether formally for the Price Funds or for the Price Fund Advisers, or for 

both), be involved in establishing policies and implementing decisions which will have different 

effects on these entities. The participation of the Covered Officers in such activities is inherent 

in the contractual relationship between each Price Fund and its respective Price Fund Adviser. 

Such participation is also consistent with the performance by the Covered Officers of their duties 

as officers of the Price Funds and, if consistent with the provisions of the Investment Company 

Act and the Investment Advisers Act, it will be deemed to have been handled ethically. 

Other conflicts of interest are covered by the Price Funds S-O Code, even if these conflicts of 

interest are not addressed by or subject to provisions in the Investment Company Act and the 

Investment Advisers Act. 

Whenever a Covered Officer is confronted with a conflict of interest situation where he or she is 

uncertain as to the appropriate action to be taken, he or she should discuss the matter with the 

Chairperson of Group’s Ethics Committee or another member of the Committee. 

Handling of Specific Types of Conflicts. Each Covered Officer (and close family members) 

must not: 

              Entertainment. Accept entertainment from any company with which any Price 

              Fund or any Price Fund Adviser has current or prospective business dealings, 

              including portfolio companies, unless such entertainment is in full compliance 

              with the policy on entertainment as set forth in the Group Code. 

              Gifts. Accept any gifts, except as permitted by the Group Code. 

               Improper Personal Influence. Use his or her personal influence or personal 

               relationships improperly to influence investment decisions, brokerage allocations 

               or financial reporting by the Price Funds to the detriment of any one or more of 

               the Price Funds. 

               Taking Action at the Expense of a Price Fund. Cause a Price Fund to take 

               action, or fail to take action, for the personal benefit of the Covered Officer rather 

               than for the benefit of one or more of the Price Funds. 

               Misuse of Price Funds’ Transaction Information. Use knowledge of portfolio 

               transactions made or contemplated for a Price Fund or any other clients of the 

               Price Fund Advisers to trade personally or cause others to trade in order to take 

               advantage of or avoid the market impact of such portfolio transactions. 

               Outside Business Activities. Engage in any outside business activity that 

               detracts from a Covered Officer’s ability to devote appropriate time and attention 

               to his or her responsibilities to a Price Fund. 

               Service Providers. Excluding Group and its affiliates, have any ownership 

               interest in, or any consulting or employment relationship with, any of the Price 

               Funds’ service providers, except that an ownership interest in public companies is 

               permitted 

               Receipt of Payments. Have a direct or indirect financial interest in commissions, 

               transaction charges, spreads or other payments paid by a Price Fund for effecting 

               portfolio transactions or for selling or redeeming shares other than an interest 

               (such as compensation or equity ownership) arising from the Covered Officer’s 

               employment by Group or any of its affiliates. 

               Service as a Director or Trustee. Serve as a director, trustee or officer of any 

               public or private company or a non-profit organization that issues securities 

               eligible for purchase by any of the Price Funds, unless approval is obtained as 

               required by the Group Code. 

IV. Covered Officers’ Specific Obligations and Accountabilities.   

               A. Disclosure Requirements and Controls. Each Covered Officer must 

               familiarize himself or herself with the disclosure requirements (Form N-1A registration 

               statement, proxy (Schedule 14A), shareholder reports, Forms N-SAR, N-CSR, etc.) 

               applicable to the Price Funds and the disclosure controls and procedures of the Price 

               Fund and the Price Fund Advisers. 

               B. Compliance with Applicable Law. It is the responsibility of each Covered 

               Officer to promote compliance with all laws, rules and regulations applicable to the Price 

               Funds and the Price Fund Advisers. Each Covered Officer should, to the extent 

               appropriate within his or her area of responsibility, consult with other officers and 

               employees of the Price Funds and the Price Fund Advisers and take other appropriate 

               steps with the goal of promoting full, fair, accurate, timely and understandable disclosure 

               in the reports and documents the Price Funds file with, or submit to, the SEC, and in 

               other public communications made by the Price Funds. 

               C. Fair Disclosure. Each Covered Officer must not knowingly misrepresent, or 

               cause others to misrepresent, facts about a Price Fund to others, whether within or 

               outside the Price organization, including to the Price Fund’s directors and auditors, and 

               to governmental regulators and self-regulatory organizations. 

               D. Initial and Annual Affirmations. Each Covered Officer must:

                     1. Upon adoption of the Price Funds S-O Code (or thereafter, as applicable, upon 

                     becoming a Covered Officer), affirm in writing that he or she has received, read, 

                     and understands the Price Funds S-O Code. 

                     2. Annually affirm that he or she has complied with the requirements of the Price 

                     Funds S-O Code. 

               E. Reporting of Material Violations of the Price Funds S-O Code. If a 

               Covered Officer becomes aware of any material violation of the Price Funds S-O Code 

               or laws and governmental rules and regulations applicable to the operations of the 

               Price Funds, he or she must promptly report the violation (“Report”) to the Chief 

               Legal Counsel of the Price Funds (“CLC”). Failure to report a material violation will 

               be considered itself a violation of the Price Funds S-O Code. The CLC is identified in 

               the attached Exhibit B. 

               It is the Price Funds policy that no retaliation or other adverse action will be taken 

               against any Covered Officer or other employee of a Price Fund, a Price Fund Adviser 

               or their affiliates based upon any lawful actions of the Covered Officer or employee 

               with respect to a Report made in good faith. 

               F. Annual Disclosures. Each Covered Officer must report, at least annually, all 

               affiliations or other relationships as called for in the “Annual Questionnaire for 

               Executive Officers and/or Employee Directors/Trustees of Group and the Price Funds.” 

V. Administration of the Price Funds S-O Code. The Ethics Committee is responsible for 

administering the Price Funds S-O Code and applying its provisions to specific situations in 

which questions are presented. 

               A. Waivers and Interpretations. The Chairperson of the Ethics Committee has 

               the authority to interpret the Price Funds S-O Code in any particular situation and to 

               grant waivers where justified, subject to the approval of the Joint Audit Committee of 

               the Price Funds. All material interpretations concerning Covered Officers will be 

               reported to the Joint Audit Committee of the Price Funds at its next meeting. Waivers, 

               including implicit waivers, to Covered Officers will be publicly disclosed as required 

               in the Instructions to N-CSR. Pursuant to the definition in the Regulations, an implicit 

               waiver means a Price Fund’s failure to take action within a reasonable period of time 

               regarding a material departure from a provision of the Price Funds S-O Code that has 

               been made known to an “executive officer” (as defined in Rule 3b-7 under the 

               Securities Exchange Act of 1934) of a Price Fund. An executive officer of a Price 

               Fund includes its president and any vice-president in charge of a principal business 

               unit, division or function. 

               B. Violations/Investigations. The following procedures will be followed in 

               investigating and enforcing the Price Funds S-O Code: 

                     1. The CLC will take or cause to be taken appropriate action to 

                     investigate any potential or actual violation reported to him or her. 

                     2. The CLC, after consultation if deemed appropriate with Outside 

                     Counsel to the Price Funds, will make a recommendation to the 

                     appropriate Price Funds Board regarding the action to be taken with 

                     regard to each material violation. Such action could include any of the 

                     following: a letter of censure or suspension, a fine, a suspension of trading 

                     privileges or termination of officership or employment. In addition, the 

                     violator may be required to surrender any profit realized (or loss avoided) 

                     from any activity that is in violation of the Price Funds S-O Code. 

VI. Amendments to the Price Funds S-O Code. Except as to the contents of Exhibit A and 

Exhibit B, the Price Funds S-O Code may not be materially amended except in written form, 

which is specifically approved or ratified by a majority vote of each Price Fund Board, including 

a majority of the independent directors on each Board. 

VII. Confidentiality. All reports and records prepared or maintained pursuant to the Price 

Funds S-O Code will be considered confidential and shall be maintained and protected 

accordingly. Except as otherwise required by law, the Price Funds S-O Code or as necessary in 

connection with regulations under the Price Funds S-O Code, such matters shall not be disclosed 

to anyone other than the directors of the appropriate Price Fund Board, Outside Counsel to the 

Price Funds, members of the Ethics Committee and the CLC and authorized persons on his or 

her staff.
