The new $6,000 senior tax deduction is available to those 65 and older with valid Social Security numbers and married couples must also file jointly to claim the deduction. This could result in significant savings for the average qualifying senior of $670 in after-tax income, according to a June 2025 report from the Council of Economic Advisors. The deduction is also worth $2,000 for single adults or $1,600 per married senior. However, it is difficult to determine exactly how much savings the new deduction will give without filing your return. The new deduction is only in effect through the 2028 tax year, and the government may extend it or make it permanent.
