Fund Summary

Fund/Class:

Fidelity® Municipal Income 2025 Fund

/Fidelity Advisor® Municipal Income 2025 Fund A, I

Investment Objective

Fidelity® Municipal Income 2025 Fund seeks as high a level of current income, exempt from federal income tax, as is consistent with the preservation of capital.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy and hold shares of the fund. In addition to the fees and expenses described below, your broker may also require you to pay brokerage commissions on purchases and sales of certain share classes of the fund.

You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the fund or certain other Fidelity® funds. More information about these and other discounts is available from your investment professional and in the "Fund Distribution" section beginning on page 38 of the prospectus. Different intermediaries may provide additional waivers or reductions of the sales charge. Please see "Sales Charge Waiver Policies Applied by Certain Intermediaries" in the "Appendix" section of the prospectus.

Shareholder fees

(fees paid directly from your investment)

	Class A	Class I
Maximum sales charge (load) on purchases (as a % of offering price)	2.75%	None
Maximum contingent deferred sales charge (as a % of the lesser of original purchase price or redemption proceeds)	NoneA	None

APurchases of $250,000 or more will not be subject to a front-end sales charge, but may be subject to a 0.50% contingent deferred sales charge (CDSC) if the intermediary firm has elected an upfront finder's fee at the time the shares are purchased, or a 0.75% CDSC if the shares purchased are recordkept in a Fidelity Advisor® 401(k) Retirement Plan.

Annual Operating Expenses

(expenses that you pay each year as a % of the value of your investment)

	Class A	Class I
Management fee	0.30%	0.30%
Distribution and/or Service (12b-1) fees	0.25%	None
Other expenses	0.10%	0.10%
Total annual operating expenses	0.65%	0.40%

This example helps compare the cost of investing in the fund with the cost of investing in other funds.Let's say, hypothetically, that the annual return for shares of the fund is 5% and that the fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

	Class A		Class I
1 year	$	340	$	41
3 years	$	477	$	128
5 years	$	627	$	224
10 years	$	1,063	$	505

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 7% of the average value of its portfolio.

Principal Investment Strategies

• Normally investing at least 80% of assets in investment-grade municipal securities whose interest is exempt from federal income tax (but may be subject to the federal alternative minimum tax).
• Managing the fund to have similar overall interest rate risk compared to a customized municipal bond index representing Fidelity Management & Research Company LLC (FMR)'s view of the performance of the fund's competitive universe.
• Allocating assets across different market sectors and maturities.
• Potentially investing more than 25% of total assets in municipal securities that finance similar types of projects.
• Analyzing the credit quality of the issuer, security-specific features, current and potential future valuation, and trading opportunities to select investments.
• Liquidating shortly after the fund's target end-date of June 30, 2025.

Principal Investment Risks

• Municipal Market Volatility.

The municipal market is volatile and can be significantly affected by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities.

• Interest Rate Changes.

Interest rate increases can cause the price of a debt security to decrease.

• Issuer-Specific Changes.

The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a security to decrease.

• Declining Yield Risk.

As the fund approaches its liquidation date, the fund's securities will mature and the fund may reinvest the proceeds in money market securities with lower yields than the securities previously held by the fund.

• Fluctuation of Yield & Liquidation Amount Risk

The amount of the fund's income distributions will vary over time, and the breakdown of returns between fund distributions and liquidation proceeds will not be predictable at the time of your investment, and you may experience a gain or loss for tax purposes.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.You could lose money by investing in the fund.

Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate.

Performance

The following information is intended to help you understand the risks of investing in the fund.

The information illustrates the changes in the performance of the fund's shares from year to year and compares the performance of the fund's shares to the performance of a securities market index and an additional index over various periods of time. The indexes have characteristics relevant to the fund's investment strategies. Index descriptions appear in the "Additional Index Information" section of the prospectus. Past performance (before and after taxes) is not an indication of future performance.

Year-by-Year Returns

The returns in the bar chart do not reflect any applicable sales charges; if sales charges were reflected, returns would be lower than those shown.

2018	2019	2020	2021
0.93%	7.18%	3.37%	0.55%

During the periods shown in the chart for Class A:	Returns	Quarter ended
Highest Quarter Return	3.00%	March 31, 2019
Lowest Quarter Return	-1.83%	March 31, 2020
Year-to-Date Return	-5.07%	June 30, 2022

Average Annual Returns

Unlike the returns in the bar chart, the returns in the table reflect the maximum applicable sales charges. After-tax returns are calculated using the historical highest individual federal marginal income tax rates, but do not reflect the impact of state or local taxes. After-tax returns for Class A are shown in the table below and after-tax returns for other classes will vary. Actual after-tax returns may differ depending on your individual circumstances. Return After Taxes on Distributions and Sale of Fund Shares may be higher than other returns for the same period due to a tax benefit of realizing a capital loss upon the sale of fund shares.

For the periods ended December 31, 2021	Past 1 year	Life of class
Class A - Return Before Taxes	-2.21%	2.04%A
Return After Taxes on Distributions	-2.21%	2.04%A
