Note to Shareholders :

Early in 2020, the outbreak and spread of COVID-19 emerged as a public health emergency that had a major influence on financial markets, primarily based on its impact on the global economy and corporate earnings. On March 11, 2020, the World Health Organization declared the COVID-19 outbreak a pandemic, citing sustained risk of further global spread. The pandemic prompted a number of measures to limit the spread of COVID-19, including travel and border restrictions, quarantines, and restrictions on large gatherings. In turn, these resulted in lower consumer activity, diminished demand for a wide range of products and services, disruption in manufacturing and supply chains, and - given the wide variability in outcomes regarding the outbreak - significant market uncertainty and volatility. To help stem the turmoil, the U.S. government took unprecedented action - in concert with the U.S. Federal Reserve and central banks around the world - to help support consumers, businesses, and the broader economy, and to limit disruption to the financial system.

In general, the overall impact of the pandemic lessened in 2021, amid a resilient economy and widespread distribution of three COVID-19 vaccines granted emergency use authorization from the U.S. Food and Drug Administration (FDA) early in the year. Still, the situation remains dynamic, and the extent and duration of its influence on financial markets and the economy is highly uncertain, due in part to a recent spike in cases based on highly contagious variants of the coronavirus.

Extreme events such as the COVID-19 crisis are exogenous shocks that can have significant adverse effects on mutual funds and their investments. Although multiple asset classes may be affected by market disruption, the duration and impact may not be the same for all types of assets. Fidelity is committed to helping you stay informed amid news about COVID-19 and during increased market volatility, and we continue to take extra steps to be responsive to customer needs. We encourage you to visit us online, where we offer ongoing updates, commentary, and analysis on the markets and our funds.

Notes to Financial Statements (Unaudited)

For the period ended July 31, 2022

1. Organization.

Fidelity Massachusetts Municipal Income Fund (the Income Fund) and Fidelity Massachusetts Municipal Money Market Fund (the Money Market Fund) are funds of Fidelity Massachusetts Municipal Trust (the Trust). The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Income Fund is a non-diversified fund. Each Fund is authorized to issue an unlimited number of shares. Shares of the Money Market Fund are only available for purchase by retail shareholders. Share transactions on the Statement of Changes in Net Assets may contain exchanges between affiliated funds. Each Fund may be affected by economic and political developments in the state of Massachusetts. Effective after the close of business on September 9, 2022, Fidelity Massachusetts Municipal Money Market Fund will be closed to new accounts with certain exceptions.

2. Investments in Fidelity Central Funds.

Funds may invest in Fidelity Central Funds, which are open-end investment companies generally available only to other investment companies and accounts managed by the investment adviser and its affiliates. The Schedule of Investments lists any Fidelity Central Funds held as an investment as of period end, but does not include the underlying holdings of each Fidelity Central Fund. An investing fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

Based on its investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the investing fund. These strategies are consistent with the investment objectives of the investing fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity Central Funds and thus a decline in the value of the investing fund.

Fidelity Central Fund	Investment Manager	Investment Objective	Investment Practices	Expense Ratio A
Fidelity Money Market Central Funds	Fidelity Management & Research Company LLC (FMR)	Each fund seeks to obtain a high level of current income consistent with the preservation of capital and liquidity.	Short-term Investments	Less than .005%

A Expenses expressed as a percentage of average net assets and are as of each underlying Central Fund's most recent annual or semi-annual shareholder report.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds which contain the significant accounting policies (including investment valuation policies) of those funds, and are not covered by the Report of Independent Registered Public Accounting Firm, are available on the Securities and Exchange Commission website or upon request.

3. Significant Accounting Policies.

Each Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services - Investment Companies . The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. Each Fund's Schedule of Investments lists any underlying mutual funds or exchange-traded funds (ETFs) but does not include the underlying holdings of these funds. The following summarizes the significant accounting policies of each Fund:

Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Board of Trustees (the Board) has delegated the day to day responsibility for the valuation of the Income Fund's investments to the Fair Value Committee (the Committee) established by the Income Fund's investment adviser. In accordance with valuation policies and procedures approved by the Board, the Income Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or currency exchange rates are not readily available or reliable, investments will be fair valued in good faith by the Committee, in accordance with procedures adopted by the Board. Factors used in determining fair value vary by investment type and may include market or investment specific events, changes in interest rates and credit quality. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees the Income Fund's valuation policies and procedures and reports to the Board on the Committee's activities and fair value determinations. The Board monitors the appropriateness of the procedures used in valuing the Income Fund's investments and ratifies the fair value determinations of the Committee.

Each Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - unadjusted quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value each Fund's investments by major category are as follows:

For the Income Fund, debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. Municipal securities are valued by pricing vendors who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

For the Money Market Fund, as permitted by compliance with certain conditions under Rule 2a-7 of the 1940 Act, securities are valued at amortized cost, which approximates fair value. The amortized cost of an instrument is determined by valuing it at its original cost and thereafter amortizing any discount or premium from its face value at a constant rate until maturity. Securities held by a money market fund are generally high quality and liquid; however, they are reflected as Level 2 because the inputs used to determine fair value are not quoted prices in an active market.

For the Income Fund, changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level as of July 31, 2022 is included at the end of each Fund's Schedule of Investments.

Investment Transactions and Income. For financial reporting purposes, the Funds' investment holdings and net asset value (NAV) include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day for the Income Fund and trades executed through the end of the current business day for the Money Market Fund. Gains and losses on securities sold are determined on the basis of identified cost. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Debt obligations may be placed on non-accrual status and related interest income may be reduced by ceasing current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured.

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expenses included in the accompanying financial statements reflect the expenses of that fund and do not include any expenses associated with any underlying mutual funds or exchange-traded funds. Although not included in a fund's expenses, a fund indirectly bears its proportionate share of these expenses through the net asset value of each underlying mutual fund or exchange-traded fund. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, each Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. Each Fund files a U.S. federal tax return, in addition to state and local tax returns as required. Each Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction.

Distributions are declared and recorded daily and paid monthly from net investment income. Distributions from realized gains, if any, are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Capital accounts are not adjusted for temporary book-tax differences which will reverse in a subsequent period.

Book-tax differences are primarily due to market discount and losses deferred due to wash sales and excise tax regulations.

The Funds purchase municipal securities whose interest, in the opinion of the issuer, is free from federal income tax. There is no assurance that the Internal Revenue Service (IRS) will agree with this opinion. In the event the IRS determines that the issuer does not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows for each Fund:

	Tax cost	Gross unrealized appreciation	Gross unrealized depreciation	Net unrealized appreciation (depreciation)
Fidelity Massachusetts Municipal Income Fund	$1,779,093,363	$ 20,566,272	$ (69,632,220)	$ (49,065,948)
Fidelity Massachusetts Municipal Money Market Fund	1,025,791,452	-	-	-

Certain of the Funds elected to defer to the next fiscal year capital losses recognized during the period November 1, 2021 to January 31, 2022. Loss deferrals were as follows:

	Capital losses
Fidelity Massachusetts Municipal Income Fund	$ (100,874)

Restricted Securities (including Private Placements). Funds may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities held at period end is included at the end of the Schedule of Investments, if applicable.

4. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities and in-kind transactions, as applicable, are noted in the table below.

	Purchases ($)	Sales ($)
Fidelity Massachusetts Municipal Income Fund	169,000,259	548,903,109

5. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Funds with investment management related services for which the Funds pay a monthly management fee. The management fee is the sum of an individual fund fee rate and an annualized group fee rate. The individual fund fee rate is applied to each Fund's average net assets. The group fee rate is based upon the monthly average net assets of a group of registered investment companies with which the investment adviser has management contracts. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the reporting period, each Fund's annualized management fee rate expressed as a percentage of each Fund's average net assets was as follows:

	Individual Rate	Group Rate	Total
Fidelity Massachusetts Municipal Income Fund	.25%	.10%	.35%
Fidelity Massachusetts Municipal Money Market Fund	.25%	.10%	.35%

During the period, the investment adviser or its affiliates waived a portion of these fees for Fidelity Massachusetts Municipal Money Market Fund.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company LLC (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for the Funds. FIIOC receives account fees and asset-based fees that vary according to account size and type of account. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, the transfer agent fees were equivalent to the following annualized rates expressed as a percentage of average net assets:

Fidelity Massachusetts Municipal Income Fund	.09%
Fidelity Massachusetts Municipal Money Market Fund	.12%

During the period, the investment adviser or its affiliates waived a portion of these fees for Fidelity Massachusetts Municipal Money Market Fund.

Accounting Fees. Fidelity Service Company, Inc. (FSC), an affiliate of the investment adviser, maintains each Fund's accounting records. The accounting fee is based on the level of average net assets for each month. For the period, the fees were equivalent to the following annualized rates:

	% of Average Net Assets
Fidelity Massachusetts Municipal Income Fund	.02
Fidelity Massachusetts Municipal Money Market Fund	.01

Interfund Trades. Funds may purchase from or sell securities to other Fidelity Funds under procedures adopted by the Board. The procedures have been designed to ensure these interfund trades are executed in accordance with Rule 17a-7 of the 1940 Act. For the Income Fund, any interfund trades are included within the respective purchases and sales amounts shown in the Purchases and Sales of Investments note. Interfund trades during the period are noted in the table below.

	Purchases ($)	Sales ($)	Realized Gain (Loss) ($)
Fidelity Massachusetts Municipal Income Fund	-	-	-
Fidelity Massachusetts Municipal Money Market Fund	5,612,643	3,000,000	-

6. Committed Line of Credit.

Certain Funds participate with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The participating funds have agreed to pay commitment fees on their pro-rata portion of the line of credit, which are reflected in Miscellaneous expenses on the Statement of Operations, and are listed below. During the period, there were no borrowings on this line of credit.

	Amount
Fidelity Massachusetts Municipal Income Fund	$ 1,002

7. Expense Reductions.

The investment adviser or its affiliates voluntarily agreed to waive certain fees for the Money Market Fund in order to avoid a negative yield. Such arrangements may be discontinued by the investment adviser at any time. For the period, the amount of the waiver was $489,090.

Through arrangements with each applicable Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce each applicable Fund's expenses. All of the applicable expense reductions are noted in the table below.

	Custodian credits
Fidelity Massachusetts Municipal Income Fund	$ 10,602
Fidelity Massachusetts Municipal Money Market Fund	704

In addition, during the period the investment adviser or an affiliate reimbursed and/or waived a portion of operating expenses as follows:

	Amount
Fidelity Massachusetts Municipal Income Fund	$ 17,029
Fidelity Massachusetts Municipal Money Market Fund	9,105

8. Other.

A fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the fund. In the normal course of business, a fund may also enter into contracts that provide general indemnifications. A fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against a fund. The risk of material loss from such claims is considered remote.

9. Coronavirus (COVID-19) Pandemic.

An outbreak of COVID-19 first detected in China during December 2019 has since spread globally and was declared a pandemic by the World Health Organization during March 2020. Developments that disrupt global economies and financial markets, such as the COVID-19 pandemic, may magnify factors that affect the Funds' performance.

10. Proposed Reorganization.

The Board of Trustees of Fidelity Massachusetts Municipal Money Market Fund approved an Agreement and Plan of Reorganization (the Agreement) between Fidelity Massachusetts Municipal Money Market Fund and Fidelity Massachusetts AMT Tax-Free Money Market Fund. The Agreement provides for the transfer of all the assets and the assumption of all the liabilities of Fidelity Massachusetts Municipal Money Market Fund in exchange for corresponding shares of Fidelity Massachusetts AMT Tax-Free Money Market Fund equal in value to the net assets of Fidelity Massachusetts Municipal Money Market Fund on the day the reorganization is effective. The reorganization does not require shareholder approval and is expected to become effective on September 16, 2022. The reorganization is expected to qualify as a tax-free transaction for federal income tax purposes with no gain or loss recognized by the funds or their shareholders.

Shareholder Expense Example

As a shareholder, you incur two types of costs: (1) transaction costs, which may include sales charges (loads) on purchase payments or redemption proceeds, as applicable and (2) ongoing costs, which generally include management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in a 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 period and held for the entire period (February 1, 2022 to July 31, 2022).

Actual Expenses

The first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class/Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If any fund is a shareholder of any underlying mutual funds or exchange-traded funds (ETFs) (the Underlying Funds), such fund indirectly bears its proportional share of the expenses of the Underlying Funds in addition to the direct expenses incurred presented in the table. These fees and expenses are not included in the annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. If any fund is a shareholder of any Underlying Funds, such fund indirectly bears its proportional share of the expenses of the Underlying Funds in addition to the direct expenses as presented in the table. These fees and expenses are not included in the annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. 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. In addition, if these transactional costs were included, your costs would have been higher.

	Annualized Expense Ratio- A	Beginning Account Value February 1, 2022	Ending Account Value July 31, 2022	Expenses Paid During Period- C February 1, 2022 to July 31, 2022

Fidelity® Massachusetts Municipal Income Fund	.46%
Actual		$ 1,000	$ 958.00	$ 2.23
Hypothetical- B		$ 1,000	$ 1,022.51	$ 2.31

Fidelity® Massachusetts Municipal Money Market Fund **	.40%
Actual		$ 1,000	$ 1,000.90	$ 1.98 **
Hypothetical- B		$ 1,000	$ 1,022.81	$ 2.01 **

A Annualized expense ratio reflects expenses net of applicable fee waivers.

B 5% return per year before expenses

C Expenses are equal to the annualized expense ratio, multiplied by the average account value over the period, multiplied by 181/ 365 (to reflect the one-half year period). The fees and expenses of any Underlying Funds are not included in each annualized expense ratio.

** If certain fees were not voluntarily waived by the investment adviser or its affiliates during the period, the annualized expense ratio and the expenses paid in the actual and hypothetical examples above would have been as shown in table below:

	Annualized Expense Ratio- A	Expenses Paid


Fidelity® Massachusetts Municipal Money Market Fund	.49%
Actual		$ 2.43
Hypothetical - B		$ 2.46

A Annualized expense ratio reflects expenses net of applicable fee waivers.
B 5% return per year before expenses

Liquidity Risk Management Program

The Securities and Exchange Commission adopted Rule 22e-4 under the Investment Company Act of 1940 (the Liquidity Rule) to promote effective liquidity risk management throughout the open-end investment company industry, thereby reducing the risk that funds will be unable to meet their redemption obligations and mitigating dilution of the interests of fund shareholders.

The Massachusetts Municipal Income Fund (the Income Fund) has adopted and implemented a liquidity risk management program pursuant to the Liquidity Rule (the Program) effective December 1, 2018. The Program is reasonably designed to assess and manage the Income Fund's liquidity risk and to comply with the requirements of the Liquidity Rule. The Income Fund's Board of Trustees (the Board) has designated the Income Fund's investment adviser as administrator of the Program. The Fidelity advisers have established a Liquidity Risk Management Committee (the LRM Committee) to manage the Program for each of the Fidelity Funds. The LRM Committee monitors the adequacy and effectiveness of implementation of the Program and on a periodic basis assesses each Fund's liquidity risk based on a variety of factors including (1) the Fund's investment strategy, (2) portfolio liquidity and cash flow projections during normal and reasonably foreseeable stressed conditions, (3) shareholder redemptions, (4) borrowings and other funding sources and (5) in the case of exchange-traded funds, certain additional factors including the effect of the Fund's prices and spreads, market participants, and basket compositions on the overall liquidity of the Fund's portfolio, as applicable.

In accordance with the Program, each of the Fund's portfolio investments is classified into one of four liquidity categories described below based on a determination of a reasonable expectation for how long it would take to convert the investment to cash (or sell or dispose of the investment) without significantly changing its market value.

Highly liquid investments - cash or convertible to cash within three business days or less
Moderately liquid investments - convertible to cash in three to seven calendar days
Less liquid investments - can be sold or disposed of, but not settled, within seven calendar days
Illiquid investments - cannot be sold or disposed of within seven calendar days

Liquidity classification determinations take into account a variety of factors including various market, trading and investment-specific considerations, as well as market depth, and generally utilize analysis from a third-party liquidity metrics service.

The Liquidity Rule places a 15% limit on a fund's illiquid investments and requires funds that do not primarily hold assets that are highly liquid investments to determine and maintain a minimum percentage of the fund's net assets to be invested in highly liquid investments (highly liquid investment minimum or HLIM). The Program includes provisions reasonably designed to comply with the 15% limit on illiquid investments and for determining, periodically reviewing and complying with the HLIM requirement as applicable.

At a recent meeting of the Fund's Board of Trustees, the LRM Committee provided a written report to the Board pertaining to the operation, adequacy, and effectiveness of implementation of the Program for the annual period from December 1, 2020 through November 30, 2021. The report concluded that the Program has been implemented and is operating effectively and is reasonably designed to assess and manage the Fund's liquidity risk.

Current 7-Day Yields

Fidelity® Massachusetts AMT Tax-Free Money Market Fund	.81%
Institutional Class	.91%
Service Class	.66%

Yield refers to the income paid by the Fund over a given period. Yield for money market funds is usually for seven-day periods, as it is here, though it is expressed as an annual percentage rate. Past performance is no guarantee of future results. Yield will vary and it's possible to lose money investing in the Fund. A portion of the Fund's expenses was reimbursed and/or waived. Absent such reimbursements and/or waivers the yield for the period ending July 31, 2022, the most recent period shown in the table, would have been .86% for Institutional Class and .62% for Service Class.

3. Significant Accounting Policies.

The Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services - Investment Companies . The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The Fund's Schedule of Investments lists any underlying mutual funds or exchange-traded funds (ETFs) but does not include the underlying holdings of these funds. The following summarizes the significant accounting policies of the Fund:

Investment Valuation. The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - unadjusted quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

As permitted by compliance with certain conditions under Rule 2a-7 of the 1940 Act, securities are valued at amortized cost, which approximates fair value. The amortized cost of an instrument is determined by valuing it at its original cost and thereafter amortizing any discount or premium from its face value at a constant rate until maturity. Securities held by a money market fund are generally high quality and liquid; however, they are reflected as Level 2 because the inputs used to determine fair value are not quoted prices in an active market.

Investment Transactions and Income. The net asset value per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time. Security transactions, including the Fund's investment activity in the Fidelity Central Funds, are accounted for as of trade date. Gains and losses on securities sold are determined on the basis of identified cost. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

Class Allocations and Expenses. Investment income, realized and unrealized capital gains and losses, common expenses of a fund, and certain fund-level expense reductions, if any, are allocated daily on a pro-rata basis to each class based on the relative net assets of each class to the total net assets of a fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred, as applicable. Certain expense reductions may also differ by class, if applicable. For the reporting period, the allocated portion of income and expenses to each class as a percent of its average net assets may vary due to the timing of recording these transactions in relation to fluctuating net assets of the classes. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expenses included in the accompanying financial statements reflect the expenses of that fund and do not include any expenses associated with any underlying mutual funds or exchange-traded funds. Although not included in a fund's expenses, a fund indirectly bears its proportionate share of these expenses through the net asset value of each underlying mutual fund or exchange-traded fund. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. The Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction.

Distributions are declared and recorded daily and paid monthly from net investment income. Distributions from realized gains, if any, are declared and recorded on the ex-dividend date. Income and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Book-tax differences are primarily due to short-term gain distributions from Fidelity Central Funds.

The Fund purchases municipal securities whose interest, in the opinion of the issuer, is free from federal income tax. There is no assurance that the IRS will agree with this opinion. In the event the IRS determines that the issuer does not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued.

As of period end, the cost and unrealized appreciation (depreciation) in securities for federal income tax purposes were as follows:

Gross unrealized appreciation	$-
Gross unrealized depreciation	-
Net unrealized appreciation (depreciation)	$-
Tax cost	$1,202,169,054

4. Fees and Other Transactions with Affiliates.

Management Fee and Expense Contract. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee that is based on an annual rate of .20% of the Fund's average net assets. Under the management contract, the investment adviser pays all other fund-level expenses, except the compensation of the independent Trustees and certain other expenses such as interest expense. The management fee is reduced by an amount equal to the fees and expenses paid by the Fund to the independent Trustees.

In addition, under the expense contract, the investment adviser pays class-level expenses for Massachusetts AMT Tax-Free Money Market Fund so that the total expenses do not exceed .35%, expressed as a percentage of class average net assets, with certain exceptions such as interest expense.

Distribution and Service Plan Fees. In accordance with Rule 12b-1 of the 1940 Act, the Fund has adopted separate Distribution and Service Plans for each class of shares. Service Class pays Fidelity Distributors Company LLC (FDC), an affiliate of the investment adviser, a Service Fee based on an annual percentage of Service Class' average net assets. In addition, FDC may pay financial intermediaries for selling shares of the Fund and providing shareholder support services. For the period, the Service Fee rate, total service fees and amounts retained by FDC were as follows:

	Service Fee	Total Fees	Retained by FDC
Service Class	.25%	$129	$129

During the period, the investment adviser or its affiliates waived a portion of these fees.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company LLC (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for the Fund. FIIOC receives asset-based fees with respect to each account. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. Each class, with the exception of Massachusetts AMT Tax-Free Money Market Fund, pays a transfer agent fee equal to an annual rate of .05% of class-level average net assets. Massachusetts AMT Tax-Free Money Market Fund pays a transfer agent fee equal to an annual rate of .10% of class-level average net assets. For the period, transfer agent fees for each class were as follows:

	Amount
Massachusetts AMT Tax-Free Money Market Fund	$101,205
Institutional Class	244,303
Service Class	26
	$345,534

During the period, the investment adviser or its affiliates waived a portion of these fees.

	Purchases ($)	Sales ($)	Realized Gain (Loss) ($)
Fidelity Massachusetts AMT Tax-Free Money Market Fund	8,505,000	6,865,000	-

5. Expense Reductions.

The investment adviser contractually agreed to reimburse Institutional Class and Service Class to the extent annual operating expenses, expressed as a percentage of each class' average net assets, exceed .20% and .45%, respectively. Some expenses, for example the compensation of the independent Trustees and certain other expenses such as interest expense, are excluded from this reimbursement. During the period, this reimbursement reduced Institutional Class and Service Class expenses by $251,702 and $27, respectively.

Additionally, the investment adviser or its affiliates voluntarily agreed to waive certain fees in order to avoid a negative yield. Such arrangements may be discontinued by the investment adviser at any time. For the period, the amount of the waiver for each class was as follows:

Massachusetts AMT Tax-Free Money Market Fund	$31,515
Institutional Class	27,967
Service Class	36

Through arrangements with the Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expenses. During the period, custodian credits reduced the Fund's expenses by $1,520.

6. Distributions to Shareholders.

Distributions to shareholders of each class were as follows:

	Six months ended July 31, 2022	Year ended January 31, 2022
