How to calculate

Works out the new $6,000 senior deduction for people 65 or older (tax years 2025 to 2028), its phase-out above $75,000 or $150,000 of income, and the federal tax it saves.

Example with the default inputs (Filing status Single, You are 65 or older Yes, Modified AGI $50,000.00, Tax year 2,026): At $50,000.00 of modified AGI, the new senior deduction is $6,000.00 and saves $720.00 of federal tax.

Method: Per person = $6,000 − 6% × (modified AGI − $75,000), or − $150,000 on a joint return, not below 0. Deduction = per person × people 65 or older on the return (both spouses on a joint return). Married filing separately gets none. Tax saved = Form 1040 tax without it − tax with it, both with the standard deduction and its $2,050 (single, head of household) or $1,650 (married) addition for each person 65 or older.

  • The deduction is for tax years 2025 to 2028 (P.L. 119-21 section 70103). It is taken whether you itemize or not.
  • Each person 65 or older must have a Social Security number valid for work, and the return must include it.
  • The tax saved treats your modified AGI as ordinary income with the standard deduction and no credits; years other than 2026 use the 2026 federal tax tables and say so.
  • An estimate, not tax advice.

  1. Filing status Single, You are 65 or older yes, Modified AGI $50,000.00 gives Senior deduction $6,000.00, Federal tax saved $720.00, Deduction ends at modified AGI $175,000.00.Source: IRC 151(d)(5)(C) (P.L. 119-21 section 70103)

How it works

  1. People who qualify: you, if 65 or older, and on a joint return your spouse, if 65 or older. Married filing separately: none.
  2. Per person = $6,000 − 6% × (modified AGI − threshold), not below 0. The threshold is $150,000 for married filing jointly and $75,000 for single, head of household, and qualifying surviving spouse.
  3. Senior deduction = per person × people who qualify.
  4. The deduction ends where 6% of the excess reaches $6,000: threshold + $100,000.

Tax saved: two 2026 Forms 1040, one without and one with the deduction. Both treat the modified AGI as ordinary income, take the standard deduction ($16,100 single, $32,200 jointly or surviving spouse, $24,150 head of household, $16,100 separately) plus $2,050 (single, head of household) or $1,650 (married, surviving spouse) for each person 65 or older, and use the Tax Table below $100,000 of taxable income (the rate schedule at the middle of the $50 row, rounded to whole dollars) and the rate schedule above. Tax saved = tax without − tax with.

When the data is out of date

The deduction is fixed by law at $6,000 for 2025 to 2028 and is not indexed. The tax saved uses the 2026 federal tables: a tax year other than 2026 uses them and says so.

Worked examples by hand

Single, 65, $50,000 of modified AGI. Below $75,000, so the full $6,000. Without it: 50,000 − 18,150 = $31,850 taxable; Tax Table row middle $31,875: 1,240 + 12% × 19,475 = $3,577. With it: $25,850 taxable; row middle $25,875: 1,240 + 12% × 13,475 = $2,857. Tax saved $720.

Married filing jointly, both 65, $180,000. 6% × (180,000 − 150,000) = $1,800 off each: $4,200 each, $8,400 in all.

Single, $120,000. 6,000 − 6% × 45,000 = $3,300.

Single, $200,000. 6% × 125,000 = $7,500 is more than $6,000: $0.

Other questions people ask

What is the new senior tax deduction?

A deduction of up to $6,000 for each person aged 65 or older, added by P.L. 119-21 (the 2025 tax law) for tax years 2025 to 2028. A married couple who are both 65 or older can deduct up to $12,000. It is on Schedule 1-A and is in addition to the regular standard deduction and its extra amount for age 65.

Who qualifies?

You must be 65 or older at the end of the year (for 2026, born before January 2, 1962), have a Social Security number valid for work, and file jointly if you are married. Married people filing separately cannot claim it.

What are the income limits?

The $6,000 falls by 6% of your modified AGI over $75,000, or over $150,000 on a joint return. It reaches 0 at $175,000 for a single filer and at $250,000 on a joint return.

Do I need to itemize to get it?

No. You can take it with the standard deduction or with itemized deductions. It lowers taxable income, not AGI.

Does it make Social Security tax-free?

Not directly. It is a deduction from income, so it lowers the tax on any income, taxable Social Security included. Many retirees with modest income then owe no federal tax on their benefits.

How much tax does it save?

The deduction times your top tax rate, roughly. At 12%, $6,000 saves $720; at 22%, $1,320. If your taxable income is already 0, it saves nothing.
