How It Works
The One Big Beautiful Bill Act added a temporary "bonus" deduction for seniors age 65 and older, in effect for tax years 2025 through 2028. It is worth up to $6,000 per qualifying person, so a married couple filing jointly where both spouses are 65 or older can claim up to $12,000. The figures here are verified against IRS guidance and Rev. Proc. 2025-32. Importantly, this deduction stacks on top of the existing extra standard deduction for people 65 and older — it does not replace it. It is a below-the-line deduction, but unlike itemized deductions it is available to everyone: you can claim it whether you take the standard deduction or itemize. There is no requirement to receive Social Security, but a valid Social Security number is required on the return. The deduction phases out based on modified adjusted gross income (MAGI). The base amount is reduced by 6 cents for every dollar of MAGI above the threshold — $75,000 for single and head-of-household filers, or $150,000 for joint filers. In plain English: subtract the threshold from your MAGI, multiply by 6%, and subtract that from your base deduction. Because the phaseout is a flat 6%, the point at which the deduction disappears entirely is dynamic — it depends on your base amount. It equals the threshold plus base ÷ 6%. For a single filer with a $6,000 base, that is $75,000 + $100,000 = $175,000. For a joint couple with two qualifying seniors ($12,000 base), it is $150,000 + $200,000 = $350,000. This calculator computes that endpoint for your exact situation. Worked example: a single filer age 68 with MAGI of $90,000 has a $6,000 base. The amount over the threshold is $90,000 − $75,000 = $15,000, so the phaseout is 6% × $15,000 = $900, leaving a $5,100 deduction. This is an estimate for planning only and is not tax advice.
Formula
Base = $6,000 × number of qualifying persons 65+ Phaseout = 6% × max(0, MAGI − threshold) Deduction = max(0, base − phaseout) Fully phased out at: threshold + base ÷ 6%
Examples
Single, age 68, one qualifying person, $90,000 MAGI
Base $6,000 minus 6% × ($90,000 − $75,000) = $900, leaving a $5,100 deduction.
Married filing jointly, both 65+, $160,000 MAGI
Base $12,000 minus 6% × ($160,000 − $150,000) = $600, leaving an $11,400 deduction.
Frequently Asked Questions
Who qualifies for the senior deduction?
Taxpayers who are age 65 or older by the end of the tax year. On a joint return, each spouse who is 65 or older counts separately, so a couple where both qualify can claim two $6,000 amounts (up to $12,000 before phaseout). A valid Social Security number is required for each person claiming it.
Does this replace the existing extra standard deduction for seniors?
No. This new bonus deduction stacks on top of the existing additional standard deduction that people 65 and older already receive. You get both, subject to the income phaseout on the new bonus amount.
Can I claim it if I take the standard deduction?
Yes. Although it is technically a below-the-line deduction, it is available to both standard-deduction filers and itemizers. You do not have to itemize to benefit from it.
Do I need to be receiving Social Security?
No. There is no requirement to be collecting Social Security benefits. Eligibility is based on your age (65 or older) and your income, not on whether you have claimed Social Security. You do, however, need a valid SSN on the return.
How does the phaseout work?
Your base deduction is reduced by 6% of the amount your MAGI exceeds the threshold ($75,000 single/HoH, $150,000 joint). The deduction is fully phased out at the threshold plus your base divided by 6% — for example $175,000 for a single filer with a $6,000 base, or $350,000 for a joint couple with a $12,000 base.
What is the maximum deduction?
Up to $6,000 per qualifying person age 65 or older, before phaseout. A single senior can claim up to $6,000; a married couple filing jointly where both are 65+ can claim up to $12,000. Higher-income taxpayers receive a reduced amount or none at all.
How long is the senior deduction available?
It is temporary, applying to tax years 2025 through 2028. Unless Congress extends it, it sunsets after 2028. The amounts and thresholds are based on current IRS/OBBBA guidance.
Is this the same as tax on Social Security being eliminated?
No. This is a separate income deduction for seniors; it does not change how Social Security benefits themselves are taxed. It simply reduces your taxable income by up to $6,000 per qualifying person, subject to the phaseout.
