The One Big Beautiful Bill added a brand-new deduction for older taxpayers: $6,000 per person age 65 and older - $12,000 for a couple who both qualify - for tax years 2025 through 2028. It stacks on top of the standard deduction or itemized deductions either way, which is why it is sometimes described as the 'no tax on Social Security' benefit: for most beneficiaries it shelters a Social Security check's worth of income, though the law technically applies to any income of a qualifying senior.
The catch is a fast phase-out: 6 cents per dollar of modified AGI over $75,000 single ($150,000 joint), so the deduction survives only below $175,000 / $250,000. Enter filing status, senior count, and MAGI - the calculator returns the exact surviving amount, and the table shows the whole ladder.
How to use
- Pick filing status and how many members of the household are 65 or older (you reach 65 on January 1 of the year you turn 65 for this purpose).
- Enter modified AGI - roughly AGI with certain foreign and tax-exempt additions; most retirees can read AGI straight off line 11 of Form 1040.
- Read the surviving deduction: full $6,000 per senior below the threshold, shaved 6% per dollar above it, zero at $175,000 single or $250,000 joint.
Frequently asked questions
Who counts as a senior for the $6,000 deduction?
Anyone who turns 65 by the end of the tax year - and the tax code is generous at the boundary: you are treated as reaching 65 on the day BEFORE your 65th birthday, so someone born January 1, 1961 counts as 65 for tax year 2025. The deduction is per qualifying person, is not dependent on Social Security receipt, and works whether or not you have any wage income at all.
How does the 6% phase-out actually compute?
Subtract the threshold ($75,000 single, $150,000 joint) from your MAGI, multiply the excess by 6%, and remove that from the $6,000-per-senior base. A single senior at $100,000 MAGI keeps $6,000 minus 6% of $25,000 - $1,500 - so $4,500 survives; at $125,000 it is $3,000; past $175,000 single or $250,000 joint nothing remains. The ladder table above prints the whole curve for both filing statuses.
Does it stack with the regular standard deduction?
Yes - that is the design. The senior deduction is its own line, claimable on top of the standard deduction (itself up to $16,100 / $32,200 in 2026 for under-65 amounts, plus the separate additional standard deduction for age 65+ and blind filers) or on top of itemized deductions. It also cannot turn your return into a loss: like most deductions it reduces taxable income to zero at most.
Is this really 'no tax on Social Security'?
Only loosely. Social Security benefits became taxable through a formula with unchanged thresholds since the 1980s and 1990s, which dragged more beneficiaries into tax every year; the OBBBA senior deduction is the workaround that shelters up to $6,000 ($12,000 joint) of ANY income for seniors, which for most beneficiaries covers the taxable slice of their benefits. The distinction matters for planners: higher-income seniors past the phase-out still pay tax on Social Security, and the deduction does not change benefit taxation formulas at all.
