Social Security Check Tax Cut Act

S 1109, the Social Security Check Tax Cut Act, temporarily reduces how much of Social Security benefits counts toward taxable income for retirees and survivors. It applies to taxable years 2026 and 2027, cutting the taxable portion by 10% in 2026 and 20% in 2027 for benefits under old-age/survivors programs (Section 202 of the Social Security Act). The bill also requires funding equal to the revenue loss to be transferred to Social Security trust funds to protect their solvency. This change directly affects Social Security beneficiaries receiving retirement or survivor benefits during those years.
