The Rules That Decide Your Number
The senior phase-out is the steepest in the whole bill: 6 cents off per dollar of MAGI above $75,000 (single) — meaning the $6,000 is fully gone by $175,000. RMD planning interacts directly: a QCD (qualified charitable distribution) moves money out of MAGI entirely, restoring deduction room in a way a plain charitable deduction cannot match at these levels.
The full rules, caps and phase-outs for every deduction are in one table on the OBBBA rules page.
Worked Example
Flo is 76 with $92,000 of MAGI from RMDs, pension and interest.
- • Deductible amount: $4,980
- • Federal income tax savings: $1,096 (at the 22% marginal rate)
- • Per biweekly paycheck: $42
The deduction is above-the-line, so it stacks on your standard deduction automatically — nothing to itemize, nothing to elect.

Frequently Asked Questions
Can a QCD increase my senior deduction?
Yes, indirectly and powerfully: QCDs satisfy your RMD while excluding that income from MAGI, which lowers the phase-out reduction on your $6,000 deduction. At the margin, a QCD dollar can save more than an itemized charitable dollar for seniors near the phase-out.
Do I need to itemize deductions to claim the $6,000 senior deduction?
No. The senior deduction is an above-the-line adjustment on Schedule 1-A, so it applies even if you take the standard deduction (which most seniors do).
