What is the OBBBA Senior Bonus Deduction?
The senior bonus deduction is a new federal tax break from the One Big Beautiful Bill Act (Public Law 119-21, § 70103), signed into law on July 4, 2025, and codified as IRC § 151(d)(5)(C). If you're 65 or older, you can deduct up to $6,000 per qualified person ($12,000 for a married couple where both spouses are 65+).
The bonus is a from-AGI deduction available to non-itemizers under § 63(b), claimed on the new Schedule 1-A and carried to Form 1040 line 13b. That is not the same as an above-the-line adjustment: it reduces taxable income but leaves your AGI alone, so it will not move any AGI-based phase-out. You can take it whether you use the regular standard deduction or itemize on Schedule A, and it stacks on top of the existing age-65 additional standard deduction, which means qualifying seniors get both.
This one is temporary. It only applies to tax years beginning before January 1, 2029, which covers 2025, 2026, 2027, and 2028 returns. Unless Congress extends it, the deduction goes away for 2029.
How the Phase-Out Works
Higher earners see the bonus shrink as MAGI rises. Each qualifying individual's $6,000 slot drops by 6 cents for every $1 of MAGI above the threshold — so a joint return with two qualifying spouses gives up 12 cents per dollar against its $12,000 base:
- Single, Head of Household, Qualifying Surviving Spouse: threshold = $75,000
- Married Filing Jointly: threshold = $150,000
- Married Filing Separately: ineligible at any income level
The reduction is capped at the base bonus (it can't go negative), so the deduction is fully phased out at these MAGI levels:
- Single / HoH / QSS, one senior: $175,000 (= $75k + $6k/0.06)
- MFJ, one spouse qualifying: $250,000 (= $150k + $6k/0.06)
- MFJ, both spouses qualifying: $250,000 as well — the extra $6,000 comes with its own 6% phase-out, so the second slot runs out at exactly the same income
Worked Examples
Example 1, single filer, age 68, MAGI $90,000: MAGI is $15,000 over the $75k threshold. Phase-out = $15,000 × 6% = $900. Final bonus = $6,000 − $900 = $5,100. At a 22% marginal rate, that's about $1,122 in federal tax savings.
Example 2, MFJ, both spouses 65+, MAGI $200,000: Base bonus = $12,000. MAGI is $50,000 over the $150k threshold. Each spouse's slot drops by $50,000 × 6% = $3,000, so the total phase-out is $6,000. Final bonus = $12,000 − $6,000 = $6,000. At a 24% marginal rate, that's roughly $1,440 saved.
Example 3, MFJ, both 65+, MAGI $260,000: Each $6,000 slot is wiped out by the 6% phase-out once MAGI passes $250,000, so the final bonus is $0. No savings at this income level.
Senior Bonus Deduction by Income Level
The table below shows the OBBBA senior bonus and estimated federal tax savings for a single filer age 65+ at the 22% marginal rate. Notice how the phase-out eats into the deduction dollar-for-dollar once MAGI crosses $75,000.

|---|---|---|---|---|
| $0 | $0 | $0 | $6,000 | $1,320 |

| $200,000+ | $125,000+ | Capped at $6,000 | $0 | $0 |
Married Filing Jointly (both spouses 65+)
| MAGI | Excess over $150k | Phase-out reduction (12% of excess) | Final senior bonus | Savings @ 22% |
|---|---|---|---|---|
| $100,000 | $0 | $0 | $12,000 | $2,640 |
| $150,000 | $0 | $0 | $12,000 | $2,640 |

Planning for 2025–2028
The four-year window opens up some real planning moves for retirees near the phase-out thresholds:
- Time Roth conversions. A big Roth conversion can spike your MAGI and wipe out the bonus. Spread conversions across multiple years, or skip them in years you'd lose the deduction.
- Delay Social Security. Waiting to claim benefits until age 70 keeps MAGI lower during the early retirement years when the bonus matters most.
- Use the 65 to 72 low-MAGI window. SECURE 2.0 pushed RMDs to age 73, so seniors between 65 and 72 often have a natural low-income window that pairs nicely with the bonus.
- Bunch charitable contributions. In years you itemize (maybe via a donor-advised fund), the senior bonus still applies on top, so you get both benefits.
- Harvest capital losses. Realized losses reduce MAGI and can keep the bonus from phasing out.
- Check your state rules. Some states decouple from federal deductions, so the senior bonus may not flow through to your state return.

Frequently Asked Questions
Common questions about senior bonus deduction calculator
What is the OBBBA senior bonus deduction?
It's a new temporary federal deduction from the One Big Beautiful Bill Act (Public Law 119-21, § 70103). If you're 65 or older, you can deduct up to $6,000 ($12,000 for a married couple where both are 65+). It's codified as IRC § 151(d)(5)(C) and applies to tax years 2025 through 2028 only. You claim it on new Schedule 1-A, and it stacks on top of the regular standard deduction. You can also take it if you itemize.
Who qualifies for the $6,000 senior deduction?
You qualify if you turn 65 on or before December 31 of the tax year, have a valid Social Security number on the return, and don't file as Married Filing Separately. Non-resident aliens and anyone claimed as a dependent are out. Your MAGI also has to fall below the full-phase-out ceiling described below.
How does the phase-out work for high earners?
The 6% phase-out runs per qualifying individual: each $6,000 slot is reduced by 6% of MAGI above $75,000 for singles / HoH / QSS, or above $150,000 for MFJ. A joint return with two qualifying spouses therefore loses 12% of the excess against its $12,000 base. Single filers lose the deduction entirely at MAGI $175,000, and MFJ couples lose it at $250,000 whether one or both spouses qualify.
Can I claim this if I itemize deductions?
Yes. The senior bonus is computed on Schedule 1-A and, unlike itemized deductions, is available to non-itemizers under § 63(b). You get it whether you take the standard deduction or itemize on Schedule A. It is a from-AGI deduction, though — it comes off after AGI on Form 1040 line 13b, so it does not lower the AGI other rules key off.
When does the senior bonus deduction expire?
It sunsets after tax year 2028. The statute at § 151(d)(5)(C)(i) specifies "a taxable year beginning before January 1, 2029." Unless Congress extends it, 2029 returns won't include the bonus. Plan any Roth conversions or income-timing moves with the four-year window in mind.
What is Modified AGI for this deduction?
MAGI is your regular AGI plus any foreign earned income exclusion (IRC § 911), Puerto Rico-source exclusion (§ 933), or U.S. territory possessions exclusion (§ 931). For most U.S. seniors, MAGI just equals AGI. Non-taxable Social Security benefits are not added back. Only the taxable portion of Social Security (already in AGI) counts.
Do both spouses need to be 65+ to get the full $12,000?
Yes. Each $6,000 slot is per qualified person. If one spouse is 66 and the other is 60 on a joint return, you get $6,000 (not $12,000), and the $150,000 phase-out threshold still applies. Once the younger spouse turns 65, the couple can claim the full $12,000 in that tax year.
How much tax will this actually save me?
Your real savings are the final deduction amount times your marginal federal tax bracket. A single filer with $80,000 MAGI in the 22% bracket would see the bonus reduced by $300 (6% of $5,000 excess) to $5,700, saving roughly $1,254 in federal tax. An MFJ couple at $140,000 MAGI with both spouses 65+ would get the full $12,000 and save $2,880 at the 24% marginal rate.
