Senior bonus deduction
$4,500
Max before phase-out
$6,000
Based on IRC Section 70103 (OBBBA), tax years 2025-2028. Stacks on top of the regular standard deduction and the existing age-65+ add-on. Not available to Married Filing Separately. Not tax advice.

The formula

Per qualifying person (age 65+): $6,000, reduced by 6 cents per $1 of MAGI above the threshold Threshold: $75,000 (Single/HoH) or $150,000 (Married Filing Jointly) Fully phased out: $175,000 (Single/HoH) or $250,000 (MFJ, both spouses 65+) For MFJ with both spouses 65+, EACH spouse's $6,000 phases out independently using the same household MAGI
Example

Single filer, age 70, MAGI $100,000: $25,000 over the threshold means a $1,500 reduction, leaving a $4,500 deduction - worth about $990 in federal tax savings at a 22% marginal rate.

Step-by-step guide

  1. Confirm you were 65 or older by December 31 of the tax year - no separate certification needed, just your date of birth on the return.
  2. Select your filing status and how many spouses qualify (Married Filing Separately is not eligible at all).
  3. Enter your MAGI and read your estimated deduction - this is above-the-line, meaning you get it whether you itemize or take the standard deduction.

Why this stacks with (and differs from) the existing senior deduction

This new $6,000 OBBBA bonus is completely separate from the older, permanent additional standard deduction for age 65+ (about $2,000 single or $1,600 per spouse married) that's existed in the tax code for decades. You can claim both at the same time - they're not alternatives. The key difference: the older age-65 add-on only benefits people who take the standard deduction, while this new $6,000 bonus applies whether you take the standard deduction or itemize on Schedule A. A senior who itemizes substantial mortgage interest and state taxes still gets the full $6,000 bonus on top, as long as their MAGI is under the phase-out.

Common mistakes

Assuming Married Filing Separately still gets a partial bonus - it doesn't. Filing separately disqualifies you from this deduction entirely, not just reduces it.
Confusing this with the older age-65+ standard deduction add-on - they're separate, stackable benefits, not the same thing described differently.

Frequently asked questions

Does taxable Social Security income count toward MAGI for this deduction?

Yes - the taxable portion of your Social Security benefits counts toward your Modified Adjusted Gross Income, which can be an easy detail to overlook when estimating where you fall relative to the phase-out threshold.

Is this deduction available every year going forward?

No - it's only available for tax years 2025 through 2028 as currently written. It would take new legislation from Congress to extend it beyond 2028.

Can someone claimed as a dependent on another return claim this?

No - if you're claimed as a dependent on someone else's tax return, you're not eligible for this deduction, regardless of your age.
