What is the senior tax deduction calculator 2026?

In short

A single 65-year-old with $100,000 MAGI gets a $4,500 senior deduction ($6,000 minus the 6% phase-out on $25,000 of excess income), saving about $990 of federal tax at 22%. A couple both 65+ with $120,000 MAGI — comfortably in the 12% bracket — gets the full $12,000, worth $1,440 at 12%.

This calculator computes the OBBBA senior deduction for tax years 2025–2028: $6,000 per person aged 65+, with EACH person's $6,000 reduced by 6% of MAGI above $75,000 (single) / $150,000 (joint) — fully phased out at $175,000 / $250,000. It stacks with the regular age-65 additional standard deduction and works whether or not you itemize.

How to use this calculator

  1. 1Pick your filing status — married couples must file jointly to claim this deduction.
  2. 2Mark whether you (and your spouse) are 65 or older by December 31 of the tax year.
  3. 3Enter your MAGI — for most retirees this is AGI including taxable Social Security, pensions, and IRA withdrawals.
  4. 4Read the deduction after phase-out and the federal tax it actually saves.

The formula

per person=max(0,$6,000−6%×MAGI excess)
deduction=per person×seniors 65+
tax saved=tax(TI)−tax(TI−deduction)
Per person 65+: deduction = max(0, $6,000 − 6% × max(0, MAGI − threshold)). Total = per-person amount × qualifying seniors. Tax saved = tax(taxable) − tax(taxable − deduction).
$6,000
— Per qualifying person 65+ ($12,000 when both spouses qualify)
threshold
— $75,000 single / $150,000 joint MAGI
6%
— Phase-out rate applied to EACH person's $6,000 — couples lose 12% of excess in total

Common use cases

  • Retirees 65+ checking what the 2025–2028 bonus deduction is worth on top of the regular senior standard deduction
  • Planning Roth conversions or IRA withdrawals around the $75,000/$150,000 phase-out line
  • Couples where only one spouse is 65 confirming they still get one $6,000 deduction

Limitations & assumptions

  • You must have a valid SSN, and married taxpayers generally must file jointly — married filing separately gets $0.
  • This is NOT the same as ‘no tax on Social Security’ — benefit taxation rules are unchanged; this is a flat deduction.
  • MAGI here is AGI plus foreign-income exclusions; the calculator treats your input as MAGI directly.
  • The amounts and thresholds are fixed by statute through 2028 and do not inflation-adjust.
