The senior bonus deduction: the new $6,000 tax break for retirees 65+
Tucked inside the 2025 tax law is a benefit a lot of retirees still don’t know they have: an extra deduction worth up to $6,000 per person ($12,000 for a couple) just for being 65 or older. It stacks on top of every other deduction you already get, it’s available whether you itemize or not, and for many retirees it quietly trims the tax on their Social Security. The catch: it phases out as income rises, it leans on a MAGI figure that your pension, TSP, and RMDs all feed, and it disappears after 2028. This guide explains exactly how it works in 2026, who gets the full amount, and — with a calculator — what it’s worth to you.
1. What it is
The senior bonus deduction is a new federal income-tax deduction created by the One Big Beautiful Bill Act (OBBBA, P.L. 119-21) for tax years 2025 through 2028. If you’re 65 or older, it lets you deduct up to $6,000 from your taxable income — on top of your standard deduction (or your itemized deductions) and on top of the existing age-65 add-on. It’s claimed on the new Schedule 1-A and doesn’t require itemizing.
Despite the headlines, OBBBA did not exempt Social Security from federal tax. This deduction is what actually passed. It indirectly reduces tax on benefits for many retirees by lowering taxable income — but the underlying taxation of Social Security rules are unchanged.
2. How much — $6,000 / $12,000
The base amount is $6,000 per qualifying person. For a married couple filing jointly where both spouses are 65 or older, that’s two deductions — up to $12,000 combined. If only one spouse is 65+, the couple gets one $6,000. The figure is fixed (not inflation-indexed) for all four years it exists.
MFJ, one spouse 65+ → up to $6,000
MFJ, both spouses 65+ → up to $12,000
3. Who qualifies
Four conditions, all required:
- Age 65+ by the last day of the tax year. For 2026 returns, that means born on or before December 31, 1961. (The IRS treats you as 65 the day before your 65th birthday.)
- A valid Social Security number on the return. ITIN filers are excluded.
- Not married filing separately. MFS doesn’t qualify; couples must file jointly.
- Not a dependent on someone else’s return.
You do not have to be drawing Social Security, and you can claim it whether you take the standard deduction or itemize.
4. The income phaseout
This is where it gets real for federal retirees. The deduction shrinks as modified adjusted gross income (MAGI) climbs:
| Filing status | Phaseout begins | Fully gone at |
|---|---|---|
| Single / HoH / surviving spouse | $75,000 | $175,000 |
| Married filing jointly | $150,000 | $250,000 |
Above the threshold, the deduction drops by 6 cents per dollar of excess MAGI. A single filer with $130,000 MAGI loses $3,300 (6% × $55,000) and keeps $2,700. For most retirees, MAGI here is essentially your AGI — and it includes taxable Social Security, your FERS/CSRS pension, TSP withdrawals, and RMDs.
5. Estimate your deduction
Enter your filing status, whether one or both spouses are 65+, your expected MAGI, and your marginal rate. The calculator applies the phaseout and shows your senior bonus, your total standard deduction, and the rough tax savings.

6. It stacks on everything
The most common mistake is treating this as a replacement for the existing senior standard deduction. It isn’t — it’s additive. A single filer 65+ taking the standard deduction can claim all three layers:
| Layer (single, 65+, 2026) | Amount |
|---|---|
| Regular standard deduction | ~$16,100 |
| Existing additional deduction for age 65+ | ~$2,050 |
| New senior bonus deduction | up to $6,000 |
| Total | ~$24,150 |
A couple where both are 65+ stacks the joint standard deduction, two age-65 add-ons, and two $6,000 bonuses. Itemizers don’t get the standard-deduction layers but do still get the $6,000 bonus — so heavy itemizers (large medical or state-tax deductions) keep this benefit too.
7. Why federal retirees should care
Federal retirees are unusually exposed to the phaseout because so many income streams feed MAGI at once: a FERS or CSRS annuity, the supplement if you’re under 62, TSP withdrawals, taxable Social Security, and eventually RMDs. A retired GS-13/14 couple can easily land in the $150,000–$250,000 MAGI band where the joint deduction is shrinking fast.
Because Roth conversions add to MAGI dollar-for-dollar, a big conversion in a year you’d otherwise qualify can phase out part or all of your senior bonus — and nudge you up an IRMAA tier. Model the conversion and the lost deduction together before pulling the trigger.
8. The 2028 sunset & planning
The deduction is temporary — 2025 through 2028, then gone unless Congress extends it. That makes the timing of income matter. The sweet spot for many retirees is the age 65–72 window: you’re old enough to qualify, but RMDs (which start at 73) haven’t yet inflated your income. Keeping MAGI under the threshold in those years — by spacing out withdrawals, harvesting capital losses, or delaying a conversion — can preserve the full $6,000 (or $12,000) each year it’s available. Treat it as a four-year opportunity with a deadline, not a permanent fixture.
9. Frequently asked questions
What is the senior bonus deduction?
The senior bonus deduction is a new federal tax deduction created by the One Big Beautiful Bill Act for tax years 2025 through 2028. It lets taxpayers who are 65 or older deduct up to $6,000 each ($12,000 for a married couple where both spouses are 65 or older), on top of every other deduction they already receive. It is claimed on Schedule 1-A and is available whether you take the standard deduction or itemize. The deduction phases out at higher incomes and is scheduled to disappear after the 2028 tax year unless Congress extends it. Despite political messaging about ending tax on Social Security, the law did not exempt Social Security benefits; this deduction is the actual benefit that was enacted.
Who qualifies for the $6,000 senior deduction?
You qualify if you are 65 or older by the last day of the tax year, have a valid Social Security number, and are not a dependent on someone else's return. For 2026 returns, that generally means you were born on or before December 31, 1961. Married couples must file jointly to claim it; married filing separately does not qualify. Each spouse who is 65 or older gets their own $6,000, so a couple where both are 65+ can claim up to $12,000. You do not need to be receiving Social Security to claim it, and you can claim it whether you take the standard deduction or itemize.
How does the income phaseout work?
The deduction shrinks as modified adjusted gross income rises. It begins phasing out above $75,000 of MAGI for single filers and $150,000 for joint filers, reduced by 6 cents for every dollar of MAGI above the threshold. It disappears entirely at $175,000 for singles and $250,000 for couples. For example, a single filer with $130,000 of MAGI loses $3,300 (6 percent of the $55,000 over the threshold) and can claim $2,700. MAGI for this purpose is essentially your regular AGI, and it includes taxable Social Security, pension income, TSP withdrawals, and required minimum distributions, all of which push federal retirees toward the phaseout.
Does the senior deduction stack with the existing senior standard deduction?
Yes. The new senior bonus deduction does not replace anything; it adds on top. A single filer 65 or older can claim the regular standard deduction (about $16,100 for 2026), plus the existing additional standard deduction for age 65 (about $2,050 for 2026), plus the new $6,000 senior bonus. That can total roughly $24,150 in deductions for one person. A married couple where both spouses are 65 or older can stack the joint standard deduction, two additional age-65 amounts, and two $6,000 bonuses. The new deduction is also available to itemizers, who get the $6,000 even though they forgo the standard-deduction add-ons.
How long will the senior bonus deduction last?
It is temporary. The senior bonus deduction applies only to tax years 2025, 2026, 2027, and 2028, and is scheduled to sunset after 2028 unless Congress passes new legislation to extend it. That four-year window creates planning value, especially in the years between 65 and 73 before required minimum distributions begin, when many retirees have naturally lower income. Keeping MAGI under the phaseout threshold in those years, by timing Roth conversions or large withdrawals carefully, can preserve the full deduction while it lasts.
