If you heard Social Security isn't taxed anymore, that's not what passed. Congress added a deduction instead: an extra $6,000 off taxable income for people 65 and older. For plenty of retirees, that wipes out a small federal bill. Others keep only part of it, or none, depending on income and how they file. And one big December withdrawal can change the answer for the whole year.

A deduction isn't a check. It lowers the income your tax is figured on, so what it's worth depends on your bracket. In the 12% bracket, it saves about $720. A couple who both qualify can double that.

It won't last, either. The break covers tax years 2025 through 2028, then lapses unless Congress renews it, and it isn't adjusted for inflation in the meantime. So does it lower the tax on your benefits? Yes and no, and the "no" part catches a lot of people off guard.

Did last year's return pick it up?

Most software and preparers caught the deduction on returns filed this spring. Checking still takes a couple of minutes, and all you need is your copy of that return.

  1. Schedule 1-A. Open last year's Form 1040 or 1040-SR and look for this schedule, with an amount in the senior section. If you were 65 by the end of 2025 and your income was under the limits, a blank or missing schedule probably means you overpaid.
  2. The birth date. When the deduction goes missing, the software often had the wrong birth date. A paper return copied from an old template is another usual suspect.
  3. The fix, if you need one. It's Form 1040-X, and there's no rush. You generally have three years from when you filed to claim a refund.
  4. This year's withholding. Tax taken out of a pension through Form W-4P, or out of Social Security through Form W-4V, may still be set at amounts chosen before the deduction existed. Lowering it keeps more of each monthly check with you.

That settles last year. The article goes on to who qualifies for 2026, how income trims the $6,000, and what it does to the tax on your benefits.
