How to use this calculator
Choose your filing status and tick the box for each person who will be 65 or older by December 31. Enter your modified adjusted gross income (MAGI), including taxable Social Security, pension income, IRA withdrawals and investment income. The calculator shows the senior deduction, your total deductions, and the tax it saves.
Two different deductions for people 65 and older
Seniors now have two boosts, and they are separate. The first is the regular additional standard deduction for being 65 or older, which has existed for years and is permanent. The second is the senior deduction, up to $6,000 per qualifying person, created by the One Big Beautiful Bill Act for tax years 2025 through 2028. The new one is available whether you itemize or take the standard deduction, and it phases out as income rises.
How the deduction is calculated
Full deduction = $6,000 x number of qualifying people (65 or older by December 31) Excess income = MAGI minus $75,000 ($150,000 if married filing jointly) Reduction = 6% x excess income Deduction = full deduction minus reduction (not below zero), per person
The deduction disappears completely at a MAGI of $175,000 for a single filer and $250,000 for a joint return.
A worked example
A single retiree who is 66 has a MAGI of $82,000. That is $7,000 over the $75,000 threshold, so the reduction is 6% x $7,000 = $420 and the senior deduction is $6,000 - $420 = $5,580. Combined with the regular standard deduction of $18,150 (which includes the age 65 add-on), total deductions reach $23,730. Federal income tax falls by about $1,228.
A married couple filing jointly, both 66, with a MAGI of $180,000: the full deduction is $12,000. Income is $30,000 over the $150,000 threshold, so each spouse loses 6% x $30,000 = $1,800, for a combined reduction of $3,600. The deduction is $8,400.
What it does not do
The senior deduction lowers taxable income. It does not make Social Security benefits tax-free and does not change how much of your benefit is taxable, which depends on a separate formula. It also expires after tax year 2028.
Assumptions and limitations
- Tax years 2025 through 2028. The deduction is temporary.
- Age test. Each person must reach age 65 on or before the last day of the tax year and have a Social Security number on the return.
- Joint filing. Married couples must file jointly. Married filing separately cannot claim it.
- Taxable income. The saving assumes taxable income equals MAGI minus the standard deduction with the age-65 add-on. Itemizers, credits and state taxes are not modelled.
Common mistakes
Mixing up the two deductions. The $6,000 is on top of the regular age 65 standard deduction add-on, not a replacement for it.
Using the wrong income. The phase-out uses modified AGI, which includes taxable Social Security, IRA withdrawals and capital gains.
Forgetting the spouse. On a joint return each eligible spouse gets a deduction of up to $6,000.
Planning past 2028. The deduction is scheduled to end, so avoid building a long plan on it.
Frequently asked questions
Any taxpayer who is 65 or older by the end of the tax year, with a Social Security number on the return. Married couples must file jointly, and each spouse who is 65 or older can claim up to $6,000.
No. It is claimed on Schedule 1-A and is available if you take the standard deduction or itemize.
The deduction is reduced by 6% of the amount by which modified AGI exceeds $75,000, or $150,000 on a joint return. It is gone entirely at $175,000 for single filers and $250,000 for joint filers.
No. The additional standard deduction for age 65 and older is a long-standing, permanent rule. The $6,000 senior deduction is separate, temporary, and applies on top of it.
Not directly. The deduction reduces taxable income, which can lower your tax bill, but the formula that decides how much of your Social Security benefit is taxable has not changed.
It applies to tax years 2025 through 2028. Unless Congress extends it, it will not be available for 2029 and later.
