A new $6,000 tax deduction for Social Security recipients aged 65 and older will be available from 2025-2028 under the One Big Beautiful Bill Act (OBBBA). This deduction aims to reduce federal taxes on Social Security benefits for middle and lower-income seniors. Eligibility requires meeting specific income thresholds and proper filing, with higher earners facing a phase-out. The deduction is separate from existing standard deductions for seniors.
