The enhanced deduction for seniors
For tax years 2025 through 2028, each eligible individual who is 65 or older by the end of the year can claim an extra $6,000 deduction. A married couple who are both 65 or older can claim $12,000 on a joint return. The deduction is separate from, and in addition to, the long-standing additional standard deduction for age 65 — $1,650 per qualifying spouse or $2,050 for an unmarried filer in 2026 — and it is available whether or not you itemize.
How the 6% phase-out works
Each person's $6,000 is reduced by 6% of modified AGI above $75,000, or $150,000 for joint filers. There is no rounding to a whole thousand here; the reduction is a straight percentage. A single filer with $100,000 of MAGI is $25,000 over and loses $1,500, leaving $4,500. The deduction reaches zero $100,000 above the threshold, at $175,000 for single filers and $250,000 for joint filers. On a joint return where both spouses qualify, each $6,000 is reduced by the same amount.
Social Security and this deduction
The deduction does not make Social Security benefits tax-free by itself. Benefits are still included in income under the usual formula. What changes is that the extra deduction lowers taxable income, which for many retirees with modest income means less or no federal tax on their benefits in practice. Whether you see a benefit depends on your other income and deductions, which is why the combined calculator lets you test your whole picture.
Eligibility details
The age test is based on the last day of the tax year. A valid Social Security number is required for each qualifying person, and married individuals must file a joint return; the calculator returns $0 for married filing separately. A head of household or single filer can claim only their own $6,000 — a qualifying relative's age does not create a deduction for you.
Planning ideas
Because the phase-out uses MAGI, the timing of IRA withdrawals, Roth conversions and capital gains can change the deduction. A $10,000 Roth conversion that pushes MAGI further over the threshold costs an additional $600 of deduction per qualifying person, on top of the tax on the conversion itself. Model scenarios before December 31 if you have control over income timing.
Worked example
Consider a married couple, both 67, with $170,000 of MAGI on a joint return. They are $20,000 over the $150,000 threshold, so each person's deduction falls by 6% of $20,000, or $1,200. Each keeps $4,800 and together they deduct $9,600. If they also take the regular additional standard deduction of $1,650 each, their total standard deduction for 2026 is $32,200 plus $3,300 plus the $9,600 senior deduction. In the 22% bracket that $9,600 is worth roughly $2,100 of federal income tax.
