Social Security beneficiaries should review their accounts before January 1, 2026, to ensure uninterrupted payments and avoid potential tax complications. Experts advise checking earnings records, bank information, and direct deposit details, as the Social Security Administration (SSA) transitions to fully electronic payments. Beneficiaries may also consider adjusting federal tax withholdings using IRS Form W-4V to account for the estimated 2.8% cost-of-living adjustment (COLA) that will increase monthly benefits, preventing unexpected tax bills.
