Federal income tax on Social Security benefits is still on the books after President Trump’s 2025 tax law, the One Big Beautiful Bill Act. What the law added is a separate deduction. People 65 and older can subtract up to $6,000 from taxable income for 2025 through 2028, and the break shrinks once income passes $75,000 for a single filer.
A deduction, not an exemption
The IRS describes the break as an extra $6,000 per eligible person, stacked on top of the additional standard deduction seniors already get. It is effective for 2025 through 2028. Taxpayers can claim it whether they itemize or take the standard deduction.
The age test is simple. A taxpayer must reach 65 on or before the last day of the tax year, according to the IRS. Someone who turns 65 on December 30, 2026, counts for the whole 2026 return, even though the birthday lands two days before the year ends.
None of that touches the rule that decides whether benefits are taxed. The IRS’s tax topic on Social Security, last updated October 7, says benefits are taxable only when a combined income figure exceeds the base amount for the filer’s status. If benefits are the only income, they may not be taxable at all.
A deduction works at a different step. It reduces taxable income after the return has already figured how much of the benefit counts. Retirees whose benefits are partly taxable will still see that line on Form 1040. The new $6,000 simply lowers the income the tax rates are applied to.

The confusion has a source. The White House’s October 22 release on Iowa says the average senior is expected to owe no federal tax on Social Security benefits. That is an average claim, not a rule. The IRS describes a deduction with an age test and an income limit, and benefits stay taxable once combined income clears the base amount.
Married couples add the spouse’s income to their own when figuring whether benefits are taxable, the IRS tax topic says. One spouse’s pension therefore counts against the other spouse’s benefit on a joint return, and the $6,000 or $12,000 deduction comes later in the calculation.
Where the $75,000 line falls
The deduction starts to phase out when modified adjusted gross income, the IRS’s income measure after certain adjustments, tops $75,000. For joint filers the line is $150,000. Below those numbers the full amount is available. Above them, the deduction is reduced.
A single retiree at $70,000 sits under the line and keeps the full $6,000. One at $90,000 is past it and gets a smaller deduction. The IRS fact sheet gives the thresholds but not a worked example, so the exact reduction comes from the form itself.
That form is Schedule 1-A. The IRS’s notice on the senior deduction says taxpayers complete Part V of the schedule, and the result carries to line 13b of Form 1040 or 1040-SR.
Taxable IRA withdrawals, pension payments and part-time wages all count toward the income line. A retiree who takes an extra distribution to cover a roof repair can push income over $75,000 and shrink the deduction in the same year. Timing withdrawals matters more than it did before the law.
Claiming it on a return
Each person who qualifies must put a Social Security number on the return, the IRS says. Married couples must file jointly to claim the deduction. When both spouses qualify, the total is $12,000, and the phase-out begins at $150,000 of joint income.
The break is already in use. It applied to 2025 returns filed this past filing season, and the IRS published an eligibility article for seniors on February 27, 2026. The next return that carries it is the 2026 return, filed in early 2027.
The IRS now files the law’s individual provisions under its Working Families Tax Cuts banner, updated October 22. The senior deduction is linked there along with the other changes, and that is where revised guidance would appear before filing.
What a 2026 return will show
Three numbers decide the outcome: birth year, total income and how much of the benefit is taxable. A person who turned 65 in 2026 qualifies for this tax year. A person who turns 65 in January 2027 does not qualify until the 2027 return.
Income is the harder variable. Social Security alone rarely reaches $75,000, but benefits plus a pension plus withdrawals can. Retirees in that band need a projection before December, because the choices that lower income, such as delaying a withdrawal, have to be made before the year closes.
The $6,000 is not permanent. The IRS lists it only through 2028, which means the same retiree faces a different calculation on the 2029 return unless Congress extends it. Anyone planning multi-year withdrawals should treat the deduction as a four-year window, not a fixed feature.
The open question for most 65-plus households is simple: after the pension, the IRA and the benefit are added up, does the 2026 income land under the $75,000 line, or does the full $6,000 start to fade?
Will 2026 income leave the full $6,000 intact?
A retiree whose pension and IRA withdrawals push income past $75,000 in 2026 can lose part of the $6,000 deduction and not learn it until the return is prepared. Partly taxable benefits add a second calculation on top, and the two interact.
The Retirement Tax & Withdrawal Planner has a section on the senior deduction and four calculators: provisional income, IRMAA tier, RMD schedule and Roth bracket fill. The provisional-income calculator is the one that tests a planned withdrawal against the Social Security tax thresholds before the money comes out.
