Summary Prospectus

Proposed Reorganization. The Board of Trustees of Fidelity Income Fund has unanimously approved an Agreement and Plan of Reorganization ("Agreement") between Fidelity Managed Retirement 2030 Fund℠ and Fidelity Freedom® Blend 2025 Fund pursuant to which Fidelity Managed Retirement 2030 Fund℠ would be reorganized on a tax-free basis with and into Fidelity Freedom® Blend 2025 Fund. As a result of the proposed Reorganization, shareholders of Fidelity Managed Retirement 2030 Fund℠ would receive, respectively, corresponding shares of Fidelity Freedom® Blend 2025 Fund.

The Agreement provides for the transfer of all of the assets of Fidelity Managed Retirement 2030 Fund℠ in exchange for corresponding shares of Fidelity Freedom® Blend 2025 Fund equal in value to the net assets of Fidelity Managed Retirement 2030 Fund℠ and the assumption by Fidelity Freedom® Blend 2025 Fund of all of the liabilities of Fidelity Managed Retirement 2030 Fund℠. After the exchange, Fidelity Managed Retirement 2030 Fund℠ will distribute the Fidelity Freedom® Blend 2025 Fund shares to its shareholders pro rata, in liquidation of Fidelity Managed Retirement 2030 Fund℠. As a result, shareholders of Fidelity Managed Retirement 2030 Fund℠ will become shareholders of Fidelity Freedom® Blend 2025 Fund (these transactions are collectively referred to as the "Reorganization").

The Reorganization, which requires shareholder approval, is expected to take place on or about June 5, 2026. The Reorganization is expected to be a tax-free transaction. This means that neither Fidelity Managed Retirement 2030 Fund℠ nor its shareholder will recognize any gain or loss as a direct result of the Reorganization.

Effective after the close of business on the business day prior to the Reorganization, new positions in the fund may no longer be opened. Existing shareholders may continue to hold their shares and purchase additional shares through the reinvestment of dividend and capital gain distributions until the fund's Reorganization takes place.

If shareholder approval of the Reorganization cannot be achieved, Fidelity Managed Retirement 2030 Fund℠ will be liquidated pursuant to a liquidation plan approved by the Board of Trustees for Fidelity Managed Retirement 2030 Fund℠. Prior to such liquidation, Fidelity Managed Retirement 2030 Fund℠ assets will be managed to provide for sufficient liquidity to meet redemptions prior to liquidation.
