Note to Shareholders:

Early in 2020, the outbreak and spread of a new coronavirus emerged as a public health emergency that had a major influence on financial markets, primarily based on its impact on the global economy and the outlook for corporate earnings. The virus causes a respiratory disease known as COVID-19. On March 11, the World Health Organization declared the COVID-19 outbreak a pandemic, citing sustained risk of further global spread.

In the weeks following, as the crisis worsened, we witnessed an escalating human tragedy with wide-scale social and economic consequences from coronavirus-containment measures. The outbreak of COVID-19 prompted a number of measures to limit the spread, 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. Amid 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.

The situation continues to unfold, and the extent and duration of its impact on financial markets and the economy remain highly uncertain. Extreme events such as the coronavirus 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’re taking extra steps to be responsive to customer needs. We encourage you to visit our websites, where we offer ongoing updates, commentary, and analysis on the markets and our funds.

Performance: The Bottom Line

Average annual total return reflects the change in the value of an investment, assuming reinvestment of distributions from dividend income and capital gains (the profits earned upon the sale of securities that have grown in value, if any) and assuming a constant rate of performance each year. The hypothetical investment and the average annual total returns do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. During periods of reimbursement by Fidelity, a fund’s total return will be greater than it would be had the reimbursement not occurred. How a fund did yesterday is no guarantee of how it will do tomorrow.

Management's Discussion of Fund Performance

Market Recap: U.S. taxable investment-grade bonds rose strongly for the 12 months ending July 31, 2020, led by healthy demand for corporate bonds from April through July, as fixed-income markets recovered from a strong sell-off in March related to the spread of the coronavirus. The Bloomberg Barclays U.S. Aggregate Bond Index gained 10.12% for the fiscal year. Early in the period, yields steadied through the end of 2019 and into early January. They then plunged in February, amid robust investor demand for most fixed-income assets – especially U.S. Treasury bonds – as the outbreak and spread of the coronavirus threatened to hamper global economic growth and corporate earnings, leading to pockets of market illiquidity in March. Market intervention by the Fed boosted liquidity and led to a broad rally for fixed-income assets from April through July, prompting many non-U.S. investors to return to U.S. markets. Within the Bloomberg Barclays index, corporate bonds rose 12.44% for the period, topping the 11.84% advance of U.S Treasuries. Conversely, agency mortgage-backed securities (+5.43%) and asset-backed securities (+5.13%) each lagged. Outside the index, U.S. corporate high-yield bonds gained 4.14%, while Treasury Inflation-Protected Securities (TIPS) rose 10.38%.

Comments from Co-Portfolio Managers Franco Castagliuolo and Sean Corcoran: For the fiscal year, the fund gained 4.71%, roughly in line, net of fees, with the 4.78% advance of the benchmark, the Bloomberg Barclays GNMA Index. In managing the fund, we attempted to exploit market inefficiencies and identify attractively valued securities in accordance with our longer-term strategy. In doing so, we added value by keeping the fund's duration longer than that of the benchmark, meaning the fund benefited more than the GNMA index as market interest rates declined the past year. We also added value through sector allocation. Specifically, our decision to increase the fund's exposure to government mortgage-backed to-be-announced (TBA) securities issued by Fannie Mae and Freddie Mac helped; the Fannie and Freddie securities outperformed GNMAs through period end. In doing so, we increased the cash stake, in case we decide to take delivery on these TBA positions. The cash position also contributed slightly to the fund's relative result. Elsewhere, our use of swaptions to manage the fund's exposure to interest-rate volatility modestly benefited performance versus the benchmark. In contrast, our decision to overweight pools of mortgages with specified pay-ups nicked the relative return.

Notes to Financial Statements

For the period ended July 31, 2020
(Amounts in thousands except percentages)

1. Organization.

Fidelity GNMA Fund (the Fund) is a fund of Fidelity Income Fund (the Trust) and is authorized to issue an unlimited number of shares. Share transactions on the Statement of Changes in Net Assets may contain exchanges between affiliated funds. 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.

Effective January 1, 2020:

Investment advisers Fidelity Investments Money Management, Inc., FMR Co., Inc., and Fidelity SelectCo, LLC, merged with and into Fidelity Management & Research Company. In connection with the merger transactions, the resulting, merged investment adviser was then redomiciled from Massachusetts to Delaware, changed its corporate structure from a corporation to a limited liability company, and changed its name to "Fidelity Management & Research Company LLC".

Fidelity Investments Institutional Operations Company, Inc. converted from a Massachusetts corporation to a Massachusetts LLC, and changed its name to "Fidelity Investments Institutional Operations Company LLC".

2. Investments in Fidelity Central Funds.

The Fund invests 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 Fund's Schedule of Investments lists each of the Fidelity Central Funds held as of period end, if any, as an investment of the Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by the investment adviser. Annualized expenses of the Money Market Central Funds as of their most recent shareholder report date ranged from less than .005% to .01%.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds, which are not covered by the Fund's Report of Independent Registered Public Accounting Firm, are available on the SEC website or upon request.

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 following summarizes the significant accounting policies of the 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 Fund's investments to the Fair Value Committee (the Committee) established by the Fund's investment adviser. In accordance with valuation policies and procedures approved by the Board, the 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 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 Fund's investments and ratifies the fair value determinations of the Committee.

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 – 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 the Fund's investments by major category are as follows:

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. Collateralized mortgage obligations, commercial mortgage securities and U.S. government agency mortgage securities are valued by pricing vendors who utilize matrix pricing which considers prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. Swaps are marked-to-market daily based on valuations from third party pricing vendors, registered derivatives clearing organizations (clearinghouses) or broker-supplied valuations. These pricing sources may utilize inputs such as interest rate curves, credit spread curves, default possibilities and recovery rates. When independent prices are unavailable or unreliable, debt securities and swaps may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. Debt securities and swaps are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Options traded over-the-counter are valued using vendor or broker-supplied valuations and are categorized as Level 2 in the hierarchy. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

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, 2020 is included at the end of the Fund's Schedule of Investments.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and 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. Gains and losses on securities sold are determined on the basis of identified cost and include proceeds received from litigation. 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.

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. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Deferred Trustee Compensation. Under a Deferred Compensation Plan (the Plan) for the Fund, certain independent Trustees have elected to defer receipt of a portion of their annual compensation. Deferred amounts are invested in a cross-section of Fidelity funds, are marked-to-market and remain in the Fund until distributed in accordance with the Plan. The investment of deferred amounts and the offsetting payable to the Trustees of $46 are included in the accompanying Statement of Assets and Liabilities in other receivables and other payables and accrued expenses, respectively.

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. As of July 31, 2020, the Fund did not have any unrecognized tax benefits in the financial statements; nor is the Fund aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. 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 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 futures contracts, swaps, market discount, deferred trustees compensation, capital loss carryforwards and losses deferred due to wash sales.

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

Gross unrealized appreciation	$156,145
Gross unrealized depreciation	(32,470)
Net unrealized appreciation (depreciation)	$123,675
Tax Cost	$4,695,808

The tax-based components of distributable earnings as of period end were as follows:

Capital loss carryforward	$(36,160)
Net unrealized appreciation (depreciation) on securities and other investments	$123,674

Capital loss carryforwards are only available to offset future capital gains of the Fund to the extent provided by regulations and may be limited. The capital loss carryforward information presented below, including any applicable limitation, is estimated as of fiscal period end and is subject to adjustment.

No expiration
Long-term	$(36,160)

The tax character of distributions paid was as follows:

	July 31, 2020	July 31, 2019
Ordinary Income	$89,664	$ 99,743

Delayed Delivery Transactions and When-Issued Securities. During the period, the Fund transacted in securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. The securities purchased on a delayed delivery or when-issued basis are identified as such in the Fund's Schedule of Investments. The Fund may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to purchase commitments, the Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.

To-Be-Announced (TBA) Securities and Mortgage Dollar Rolls. During the period, the Fund transacted in TBA securities that involved buying or selling mortgage-backed securities (MBS) on a forward commitment basis. A TBA transaction typically does not designate the actual security to be delivered and only includes an approximate principal amount; however delivered securities must meet specified terms defined by industry guidelines, including issuer, rate and current principal amount outstanding on underlying mortgage pools. The Fund may enter into a TBA transaction with the intent to take possession of or deliver the underlying MBS, or the Fund may elect to extend the settlement by entering into either a mortgage or reverse mortgage dollar roll. Mortgage dollar rolls are transactions where a fund sells TBA securities and simultaneously agrees to repurchase MBS on a later date at a lower price and with the same counterparty. Reverse mortgage dollar rolls involve the purchase and simultaneous agreement to sell TBA securities on a later date at a lower price. Transactions in mortgage dollar rolls and reverse mortgage dollar rolls are accounted for as purchases and sales and may result in an increase to the Fund's portfolio turnover rate.

Purchases and sales of TBA securities involve risks similar to those discussed above for delayed delivery and when-issued securities. Also, if the counterparty in a mortgage dollar roll or a reverse mortgage dollar roll transaction files for bankruptcy or becomes insolvent, the Fund's right to repurchase or sell securities may be limited. Additionally, when a fund sells TBA securities without already owning or having the right to obtain the deliverable securities (an uncovered forward commitment to sell), it incurs a risk of loss because it could have to purchase the securities at a price that is higher than the price at which it sold them. A fund may be unable to purchase the deliverable securities if the corresponding market is illiquid.

TBA securities subject to a forward commitment to sell at period end are included at the end of the Fund's Schedule of Investments under the caption "TBA Sale Commitments." The proceeds and value of these commitments are reflected in the Fund's Statement of Assets and Liabilities as Receivable for TBA sale commitments and TBA sale commitments, at value, respectively.

4. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Fund's investment objective allows the Fund to enter into various types of derivative contracts, including futures contracts, options and swaps. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party.

The Fund used derivatives to increase returns, to gain exposure to certain types of assets and to manage exposure to certain risks as defined below. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the Fund may not achieve its objectives.

The Fund's use of derivatives increased or decreased its exposure to the following risk:

Interest Rate Risk

Interest rate risk relates to the fluctuations in the value of interest-bearing securities due to changes in the prevailing levels of market interest rates.

The Fund is also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that the Fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to the Fund. Derivative counterparty credit risk is managed through formal evaluation of the creditworthiness of all potential counterparties. On certain OTC derivatives such as options, the Fund attempts to reduce its exposure to counterparty credit risk by entering into an International Swaps and Derivatives Association, Inc. (ISDA) Master Agreement with each of its counterparties. The ISDA Master Agreement gives the Fund the right to terminate all transactions traded under such agreement upon the deterioration in the credit quality of the counterparty beyond specified levels. The ISDA Master Agreement gives each party the right, upon an event of default by the other party or a termination of the agreement, to close out all transactions traded under such agreement and to net amounts owed under each transaction to one net payable by one party to the other. To mitigate counterparty credit risk on bi-lateral OTC derivatives, the Fund receives collateral in the form of cash or securities once the Fund's net unrealized appreciation on outstanding derivative contracts under an ISDA Master Agreement exceeds certain applicable thresholds, subject to certain minimum transfer provisions. The collateral received is held in segregated accounts with the Fund's custodian bank in accordance with the collateral agreements entered into between the Fund, the counterparty and the Fund's custodian bank. The Fund could experience delays and costs in gaining access to the collateral even though it is held by the Fund's custodian bank. The Fund's maximum risk of loss from counterparty credit risk related to bi-lateral OTC derivatives is generally the aggregate unrealized appreciation and unpaid counterparty payments in excess of any collateral pledged by the counterparty to the Fund. For OTC written options with upfront premiums received, the Fund is obligated to perform and therefore does not have counterparty risk. For OTC written options with premiums to be received at a future date, the maximum risk of loss from counterparty credit risk is the amount of the premium in excess of any collateral pledged by the counterparty. The Fund may be required to pledge collateral for the benefit of the counterparties on bi-lateral OTC derivatives in an amount not less than each counterparty's unrealized appreciation on outstanding derivative contracts, subject to certain minimum transfer provisions, and any such pledged collateral is identified in the Schedule of Investments. Exchange-traded futures contracts are not covered by the ISDA Master Agreement; however counterparty credit risk related to exchange-traded futures contracts may be mitigated by the protection provided by the exchange on which they trade. Counterparty credit risk related to centrally cleared OTC swaps may be mitigated by the protection provided by the clearinghouse.

Investing in derivatives may involve greater risks than investing in the underlying assets directly and, to varying degrees, may involve risk of loss in excess of any initial investment and collateral received and amounts recognized in the Statement of Assets and Liabilities. In addition, there may be the risk that the change in value of the derivative contract does not correspond to the change in value of the underlying instrument.

Net Realized Gain (Loss) and Change in Net Unrealized Appreciation (Depreciation) on Derivatives. The table below, which reflects the impacts of derivatives on the financial performance of the Fund, summarizes the net realized gain (loss) and change in net unrealized appreciation (depreciation) for derivatives during the period as presented in the Statement of Operations.

Primary Risk Exposure / Derivative Type	Net Realized Gain (Loss)	Change in Net Unrealized Appreciation (Depreciation)
Interest Rate Risk
Futures Contracts	$(42,619)	$(2,319)
Purchased Options	4,662	1,232
Swaps	(1,761)	2,110
Written Options	(3,783)	(2,869)
Totals	$(43,501)	$(1,846)

A summary of the value of derivatives by primary risk exposure as of period end is included at the end of the Schedule of Investments.

Futures Contracts. A futures contract is an agreement between two parties to buy or sell a specified underlying instrument for a fixed price at a specified future date. The Fund used futures contracts to manage its exposure to the bond market and fluctuations in interest rates.

Upon entering into a futures contract, a fund is required to deposit either cash or securities (initial margin) with a clearing broker in an amount equal to a certain percentage of the face value of the contract. Futures contracts are marked-to-market daily and subsequent daily payments (variation margin) are made or received by a fund depending on the daily fluctuations in the value of the futures contracts and are recorded as unrealized appreciation or (depreciation). This receivable and/or payable, if any, is included in daily variation margin on futures contracts in the Statement of Assets and Liabilities. Realized gain or (loss) is recorded upon the expiration or closing of a futures contract. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on futures contracts during the period is presented in the Statement of Operations.

Any open futures contracts at period end are presented in the Schedule of Investments under the caption "Futures Contracts". The notional amount at value reflects each contract's exposure to the underlying instrument or index at period end. Securities deposited to meet initial margin requirements are identified in the Schedule of Investments.

Options. Options give the purchaser the right, but not the obligation, to buy (call) or sell (put) an underlying security or financial instrument at an agreed exercise or strike price between or on certain dates. Options obligate the seller (writer) to buy (put) or sell (call) an underlying instrument at the exercise or strike price or cash settle an underlying derivative instrument if the holder exercises the option on or before the expiration date. The Fund uses OTC options, such as swaptions, which are options where the underlying instrument is a swap, to manage its exposure to fluctuations in interest rates.

Upon entering into an options contract, a fund will pay or receive a premium. Premiums paid on purchased options are reflected as cost of investments and premiums received on written options are reflected as a liability on the Statement of Assets and Liabilities. Certain options may be purchased or written with premiums to be paid or received on a future date. Options are valued daily and any unrealized appreciation (depreciation) is reflected on the Statement of Assets and Liabilities. When an option is exercised, the cost or proceeds of the underlying instrument purchased or sold is adjusted by the amount of the premium. When an option is closed the Fund will realize a gain or loss depending on whether the proceeds or amount paid for the closing sale transaction is greater or less than the premium received or paid. When an option expires, gains and losses are realized to the extent of premiums received and paid, respectively. The net realized and unrealized gains (losses) on purchased options are included in the Statement of Operations in net realized gain (loss) and change in net unrealized appreciation (depreciation) on investment securities. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on written options are presented in the Statement of Operations.

Any open options at period end are presented in the Schedule of Investments under the captions "Purchased Options," "Purchased Swaptions," "Written Options" and "Written Swaptions," as applicable.

Writing puts and buying calls tend to increase exposure to the underlying instrument while buying puts and writing calls tend to decrease exposure to the underlying instrument. For purchased options, risk of loss is limited to the premium paid, and for written options, risk of loss is the change in value in excess of the premium received.

Swaps. A swap is a contract between two parties to exchange future cash flows at periodic intervals based on a notional principal amount. A centrally cleared OTC swap is a transaction executed between a fund and a dealer counterparty, then cleared by a futures commission merchant (FCM) through a clearinghouse. Once cleared, the clearinghouse serves as a central counterparty, with whom a fund exchanges cash flows for the life of the transaction, similar to transactions in futures contracts.

Centrally cleared OTC swaps require a fund to deposit either cash or securities (initial margin) with the FCM, at the instruction of and for the benefit of the clearinghouse. Securities deposited to meet initial margin requirements are identified in the Schedule of Investments. Centrally cleared OTC swaps are marked-to-market daily and subsequent payments (variation margin) are made or received depending on the daily fluctuations in the value of the swaps and are recorded as unrealized appreciation or (depreciation). These daily payments, if any, are included in receivable or payable for daily variation margin on centrally cleared OTC swaps in the Statement of Assets and Liabilities. Any premiums for centrally cleared OTC swaps are recorded periodically throughout the term of the swap to variation margin and included in unrealized appreciation (depreciation) in the Statement of Assets and Liabilities. Any premiums are recognized as realized gain (loss) upon termination or maturity of the swap.

Payments are exchanged at specified intervals, accrued daily commencing with the effective date of the contract and recorded as realized gain or (loss). Some swaps may be terminated prior to the effective date and realize a gain or loss upon termination. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on swaps during the period is presented in the Statement of Operations.

Any open swaps at period end are included in the Schedule of Investments under the caption "Swaps" and are representative of volume of activity during the period.

Interest Rate Swaps. Interest rate swaps are agreements between counterparties to exchange cash flows, one based on a fixed rate, and the other on a floating rate. The Fund entered into interest rate swaps to manage its exposure to interest rate changes. Changes in interest rates can have an effect on both the value of bond holdings as well as the amount of interest income earned. In general, the value of bonds can fall when interest rates rise and can rise when interest rates fall.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities and U.S. government securities, are noted in the table below.

	Purchases ($)	Sales ($)
Fidelity GNMA Fund	6,471,176	6,484,120

6. Fees and Other Transactions with Affiliates.

Management Fee. 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. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .20% of the Fund's average net assets and an annualized group fee rate that averaged .10% during the period. 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, the total annual management fee rate was .30% of the Fund's average net assets.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company LLC (FIIOC), an affiliate of the investment adviser, is the Fund's transfer, dividend disbursing and shareholder servicing agent. FIIOC receives an asset-based fee of .10% of the Fund's average net assets. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements.

Fund Wide Operations Fee. Pursuant to the Fund Wide Operations and Expense Agreement (FWOE), the investment adviser has agreed to provide for fund level expenses (which do not include transfer agent, compensation of the independent Trustees, interest (including commitment fees), taxes or extraordinary expenses, if any) in return for a FWOE fee equal to .35% of the Fund's average net assets less the total amount of the management fee. The FWOE paid by the Fund is reduced by an amount equal to the fees and expenses paid to the independent Trustees. For the period, the FWOE fee was equivalent to an annual rate of .05% of average net assets.

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. Interfund trades are included within the respective purchases and sales amounts shown in the Purchases and Sales of Investments note.

Other. During the period, the investment adviser reimbursed the Fund for certain losses in the amount of $36.

7. 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 Commitment fees on the Statement of Operations, and are as follows:

	Amount
Fidelity GNMA Fund	$11

During the period, there were no borrowings on this line of credit.

8. Expense Reductions.

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 by $3.

9. Other.

The 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, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

10. 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 Fund's performance.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Income Fund and Shareholders of Fidelity GNMA Fund

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Fidelity GNMA Fund (one of the funds constituting Fidelity Income Fund, referred to hereafter as the “Fund”) as of July 31, 2020, the related statement of operations for the year ended July 31, 2020, the statement of changes in net assets for each of the two years in the period ended July 31, 2020, including the related notes, and the financial highlights for each of the five years in the period ended July 31, 2020 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of July 31, 2020, 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 ended July 31, 2020 and the financial highlights for each of the five years in the period ended July 31, 2020 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of July 31, 2020 by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Trustees and Officers

The Trustees, Members of the Advisory Board (if any), and officers of the trust and fund, as applicable, are listed below. The Board of Trustees governs the fund and is responsible for protecting the interests of shareholders. The Trustees are experienced executives who meet periodically throughout the year to oversee the fund's activities, review contractual arrangements with companies that provide services to the fund, oversee management of the risks associated with such activities and contractual arrangements, and review the fund's performance. Each of the Trustees oversees 280 funds.

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust. Each Trustee who is not an interested person (as defined in the 1940 Act) of the trust and the fund is referred to herein as an Independent Trustee. Each Independent Trustee shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs. The Independent Trustees may waive this mandatory retirement age policy with respect to individual Trustees. Officers and Advisory Board Members hold office without limit in time, except that any officer or Advisory Board Member may resign or may be removed by a vote of a majority of the Trustees at any regular meeting or any special meeting of the Trustees. Except as indicated, each individual has held the office shown or other offices in the same company for the past five years.

The fund’s Statement of Additional Information (SAI) includes more information about the Trustees. To request a free copy, call Fidelity at 1-800-544-8544.

Experience, Skills, Attributes, and Qualifications of the Trustees. The Governance and Nominating Committee has adopted a statement of policy that describes the experience, qualifications, attributes, and skills that are necessary and desirable for potential Independent Trustee candidates (Statement of Policy). The Board believes that each Trustee satisfied at the time he or she was initially elected or appointed a Trustee, and continues to satisfy, the standards contemplated by the Statement of Policy. The Governance and Nominating Committee also engages professional search firms to help identify potential Independent Trustee candidates who have the experience, qualifications, attributes, and skills consistent with the Statement of Policy. From time to time, additional criteria based on the composition and skills of the current Independent Trustees, as well as experience or skills that may be appropriate in light of future changes to board composition, business conditions, and regulatory or other developments, have also been considered by the professional search firms and the Governance and Nominating Committee. In addition, the Board takes into account the Trustees' commitment and participation in Board and committee meetings, as well as their leadership of standing and ad hoc committees throughout their tenure.

In determining that a particular Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Trustees have balanced and diverse experience, qualifications, attributes, and skills, which allow the Board to operate effectively in governing the fund and protecting the interests of shareholders. Information about the specific experience, skills, attributes, and qualifications of each Trustee, which in each case led to the Board's conclusion that the Trustee should serve (or continue to serve) as a trustee of the fund, is provided below.

Board Structure and Oversight Function. Abigail P. Johnson is an interested person and currently serves as Chairman. The Trustees have determined that an interested Chairman is appropriate and benefits shareholders because an interested Chairman has a personal and professional stake in the quality and continuity of services provided to the fund. Independent Trustees exercise their informed business judgment to appoint an individual of their choosing to serve as Chairman, regardless of whether the Trustee happens to be independent or a member of management. The Independent Trustees have determined that they can act independently and effectively without having an Independent Trustee serve as Chairman and that a key structural component for assuring that they are in a position to do so is for the Independent Trustees to constitute a substantial majority for the Board. The Independent Trustees also regularly meet in executive session. Arthur E. Johnson serves as Chairman of the Independent Trustees and as such (i) acts as a liaison between the Independent Trustees and management with respect to matters important to the Independent Trustees and (ii) with management prepares agendas for Board meetings.

Fidelity^® funds are overseen by different Boards of Trustees. The fund's Board oversees Fidelity's investment-grade bond, money market, asset allocation and certain equity funds, and other Boards oversee Fidelity's high income and other equity funds. The asset allocation funds may invest in Fidelity^® funds that are overseen by such other Boards. The use of separate Boards, each with its own committee structure, allows the Trustees of each group of Fidelity^® funds to focus on the unique issues of the funds they oversee, including common research, investment, and operational issues. On occasion, the separate Boards establish joint committees to address issues of overlapping consequences for the Fidelity^® funds overseen by each Board.

The Trustees operate using a system of committees to facilitate the timely and efficient consideration of all matters of importance to the Trustees, the fund, and fund shareholders and to facilitate compliance with legal and regulatory requirements and oversight of the fund's activities and associated risks. The Board, acting through its committees, has charged FMR and its affiliates with (i) identifying events or circumstances the occurrence of which could have demonstrably adverse effects on the fund's business and/or reputation; (ii) implementing processes and controls to lessen the possibility that such events or circumstances occur or to mitigate the effects of such events or circumstances if they do occur; and (iii) creating and maintaining a system designed to evaluate continuously business and market conditions in order to facilitate the identification and implementation processes described in (i) and (ii) above. Because the day-to-day operations and activities of the fund are carried out by or through FMR, its affiliates, and other service providers, the fund's exposure to risks is mitigated but not eliminated by the processes overseen by the Trustees. While each of the Board's committees has responsibility for overseeing different aspects of the fund's activities, oversight is exercised primarily through the Operations and Audit Committees. In addition, an ad hoc Board committee of Independent Trustees has worked with FMR to enhance the Board's oversight of investment and financial risks, legal and regulatory risks, technology risks, and operational risks, including the development of additional risk reporting to the Board. Appropriate personnel, including but not limited to the fund's Chief Compliance Officer (CCO), FMR's internal auditor, the independent accountants, the fund's Treasurer and portfolio management personnel, make periodic reports to the Board's committees, as appropriate, including an annual review of Fidelity's risk management program for the Fidelity^® funds. The responsibilities of each standing committee, including their oversight responsibilities, are described further under "Standing Committees of the Trustees."

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, 2020 to July 31, 2020).

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.

	Annualized Expense Ratio-^A	Beginning Account Value February 1, 2020	Ending Account Value July 31, 2020	Expenses Paid During Period-^B February 1, 2020 to July 31, 2020
Fidelity GNMA Fund	.45%
Actual		$1,000.00	$1,028.20	$2.27
Hypothetical-^C		$1,000.00	$1,022.63	$2.26

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

^B Expenses are equal to the annualized expense ratio, multiplied by the average account value over the period, multiplied by 182/ 366 (to reflect the one-half year period). The fees and expenses of any Underlying Funds are not included in each annualized expense ratio.

^C 5% return per year before expenses

Distributions (Unaudited)

A total of 0.45% of the dividends distributed during the fiscal year was derived from interest on U.S. Government securities which is generally exempt from state income tax.

The fund designates $45,014,122 of distributions paid during the period January 01, 2020 to July 31, 2020 as qualifying to be taxed as interest-related dividends for nonresident alien shareholders.

The fund will notify shareholders in January 2021 of amounts for use in preparing 2020 income tax returns.

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 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 Fund’s liquidity risk and to comply with the requirements of the Liquidity Rule. The Fund’s Board of Trustees (the Board) has designated the 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, 2018 through November 30, 2019. 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.
