A new tax deduction for seniors aged 65 and over, available through 2028, allows a $6,000 deduction per person, reducing taxable income and potentially lowering taxes on Social Security benefits. Eligibility requires a modified adjusted gross income below set thresholds and filing a tax return. The deduction can be claimed alongside standard or itemized deductions, helping retirees avoid taxable Social Security income by lowering provisional income below key limits.
