This legislative proposal aims to provide a temporary reduction in the amount of certain Social Security and railroad retirement benefits that are subject to federal income tax. Specifically, it targets old-age and survivors insurance benefit payments and Tier 1 railroad retirement benefits, applying to taxable years beginning after December 31, 2025, and before January 1, 2028. The bill stipulates a 10 percent reduction in the taxable portion of these benefits for the 2026 tax year, which then increases to a 20 percent reduction for the 2027 tax year. To safeguard the financial integrity of critical federal programs, the bill includes a provision for the protection of Trust Funds . It mandates appropriations from the general fund to the Federal Old-Age and Survivors Trust Fund, the Federal Disability Insurance Trust Fund, and the Medicare Hospital Insurance Trust Fund. These appropriations are intended to fully offset any reduction in revenues to the Treasury resulting from the proposed tax amendment, ensuring that these vital funds remain unaffected by the temporary tax cut.
