Estimate only. Each qualifying person gets $6,000, reduced by 6% of modified AGI over $150,000. Tax saved assumes the regular 2026 standard deduction and ignores the additional standard deduction for age 65+, credits, and other deductions.

How the senior deduction is calculated

  1. Count qualifying people: you, and your spouse if filing jointly, who are 65 or older by December 31 and have a valid Social Security number.
  2. Start with $6,000 for each qualifying person.
  3. Reduce each $6,000 by 6% of modified AGI over $75,000 ($150,000 for married filing jointly).
  4. Subtract the result from taxable income on Schedule 1-A. Your savings equal the federal tax on the amount deducted.

Example: a married couple filing jointly, both 65 or older, with $160,000 of modified AGI. They are $10,000 over the $150,000 threshold, so each deduction is reduced by $600 to $5,400, for a total of $10,800. After the $32,200 standard deduction their taxable income is $127,800, in the 22% bracket, so the deduction saves about $2,376 in federal income tax.

The senior deduction lowers taxable income, but it does not change how much of your Social Security is taxable. To see that number, use the taxable Social Security calculator.

Frequently asked questions

Is Social Security tax-free now?

No. Despite the "no tax on Social Security" headlines, the law did not change how Social Security benefits are taxed. Up to 85% of your benefits can still be taxable. What changed is a new deduction of up to $6,000 per person age 65 or older, which lowers taxable income from any source. For many retirees with modest income, that deduction offsets the taxable part of their benefits, so they owe little or no federal tax on them.

Who qualifies for the $6,000 senior deduction?

You must be 65 or older by December 31 of the tax year. For 2026 that means born before January 2, 1962 (for 2025, before January 2, 1961). You need a valid Social Security number, and if you are married you must file a joint return. Married filing separately cannot claim it.

Do I need to itemize to get the senior deduction?

No. It is claimed on Schedule 1-A and is available whether you take the standard deduction or itemize. It is also in addition to the existing additional standard deduction for age 65 and older ($2,050 for single or head of household, $1,650 per qualifying spouse for married filers in 2026).

Does my spouse need to be 65 too?

Only if you want two deductions. On a joint return each spouse who is 65 or older and has a valid Social Security number gets their own $6,000, so the maximum is $12,000. If only one spouse is 65 or older, the couple gets one $6,000 deduction, subject to the joint phase-out.

What is the income limit for the senior deduction?

Each $6,000 deduction is reduced by 6% of modified AGI above $75,000 ($150,000 for married filing jointly). It reaches zero at $175,000 of MAGI for single and head of household filers and $250,000 for joint filers. For most people MAGI is simply their AGI.

What years is the senior deduction available?

Tax years 2025 through 2028. Unless Congress extends it, the deduction expires after the 2028 tax year. The regular additional standard deduction for age 65 and older is permanent and continues after 2028.

Does the senior deduction reduce how much of my Social Security is taxable?

No. The taxable portion of your benefits is figured from provisional income (other income plus tax-exempt interest plus half your benefits), and the senior deduction is not part of that formula. It is subtracted later, from taxable income. Use the taxable Social Security calculator to see how much of your benefits counts as income.

Is this calculator exact?

It is an estimate. The tax savings assume the regular standard deduction and do not include the additional 65+ standard deduction, itemized deductions, credits, or capital gains rates. Your actual savings depend on your full return.
