What Is the Senior Bonus Deduction?
The Senior Bonus Deduction is an additional federal deduction available to U.S. taxpayers who are age 65 or older by year-end. It provides $6,000 per eligible taxpayer (i.e., $12,000 when both spouses qualify on a joint return). Under current law, it applies to tax years 2025 through 2028.
- Eligibility: You’re considered 65 on the day before your 65th birthday; each spouse is tested separately.
- Coordination: This bonus is in addition to the base standard deduction and the existing age/blind additional standard deduction.
- Phaseout: Reduced by 6% of the amount your modified AGI exceeds $75,000 (single) or $150,000 (MFJ). It phases out completely at higher income levels.
- 2026 status: The $6,000 amount continues in 2026; base standard deduction amounts will be inflation-adjusted by the IRS.
Note: Always verify the year-specific instructions for Form 1040/1040-SR before filing; line references and worksheets can shift with annual updates.
How the Senior Bonus Deduction Stacks with Other Deductions
For 2025, the base standard deduction is $15,000 (Single/MFS), $22,500 (Head of Household), and $30,000 (Married Filing Jointly/Qualifying Surviving Spouse). Seniors can also claim the age/blind additional amount ($2,000 for Single/HOH, $1,600 per eligible spouse for MFJ). The Senior Bonus Deduction stacks on top of these.
| Filing Status & Situation (Age 65+) | Base Standard Deduction (2025) | Age/Blind Add-On | Senior Bonus | Potential Total |
|---|---|---|---|---|
| Single (not blind) | $15,000 | $2,000 | $6,000 | $23,000 |
| Head of Household (not blind) | $22,500 | $2,000 | $6,000 | $30,500 |
| Married Filing Jointly — one spouse 65+ | $30,000 | $1,600 | $6,000 | $37,600 |
| Married Filing Jointly — both spouses 65+ | $30,000 | $3,200 | $12,000 | $45,200 |
| Single 65+ and blind | $15,000 | $4,000 | $6,000 | $25,000 |
2026 figures will be similar but reflect inflation-adjusted base standard deduction amounts set by the IRS before the filing season.

Income Phaseout: Quick Math
Thresholds: MAGI of $75,000 (Single) or $150,000 (MFJ). Your Senior Bonus is reduced by 6% of the amount above the threshold. It phases out completely at higher incomes (e.g., around $175,000 Single and $250,000 MFJ).
| Scenario | MAGI | Reduction | Allowed |
|---|---|---|---|
| Single 65+ | $85,000 | 6% × ($85,000 − $75,000) = $600 | $5,400 |
| MFJ (both 65+) | $160,000 | 6% × ($160,000 − $150,000) = $600 | $11,400 |
| Single 65+ | $176,000 | ≥ $6,000 (fully phased out) | $0 |
MAGI = Adjusted Gross Income with certain add-backs used in phaseout tests. Check the year’s instructions for exact MAGI definition.
How to Claim It on Form 1040/1040-SR
- Confirm eligibility: You (and your spouse, if MFJ) are age 65+ by December 31 of the tax year.
- Check the age box(es): On Form 1040/1040-SR, mark the “Age 65 or older” checkbox for each eligible filer to trigger age-based computations.
- Standard vs. itemizing: Compare itemized deductions to the sum of base standard deduction + age/blind add-on + Senior Bonus; take whichever is larger.
- Watch the phaseout: If your MAGI is near/over the thresholds, use software or the IRS worksheet to compute the allowed bonus accurately.
- 2026 filing: Repeat the process; use the IRS-published 2026 inflation-adjusted standard deduction figures at that time.
Tax software typically handles the calculation automatically once you enter age and income. Paper filers should follow the year-specific worksheet and line instructions.
Planning Strategies to Maximize Your Savings
- Manage MAGI around thresholds: Time IRA withdrawals/RMDs, capital gains, and Roth conversions across years to remain under or reduce the phaseout impact.
- Coordinate with Social Security taxation: Lowering provisional income can reduce benefit taxation while preserving more of the Senior Bonus.
- Use Qualified Charitable Distributions (QCDs): If 70½+, QCDs can satisfy RMDs without boosting AGI.
- Estimate quarterly taxes: Avoid penalties by meeting safe-harbor rules (e.g., 90% current-year or 100%/110% prior-year tax).
- Re-check mid-year: Update projections each quarter if your income changes.
