For 2026 a single filer who is 65 or older gets a $16,100 standard deduction plus a $2,050 age-65 addition, and may add the $6,000 senior deduction (available 2025–2028, phasing out above $75,000 income) — up to $24,150 stacked. A married-filing-jointly couple both 65+ can stack up to $47,500.
Deduction stack at 65 (2026)
| Filing status (65+) | Base | Age-65 addition | Senior deduction | Stacked total |
|---|---|---|---|---|
| Single | $16,100 | $2,050 | $6,000 | $24,150 |
| Married filing jointly (both 65+) | $32,200 | $3,300 | $12,000 | $47,500 |
The senior deduction is reduced by 6% of income above $75,000 (single) or $150,000 (joint) and reaches zero well before high incomes.
Methodology
Each layer computed from QuantCalc's parity-tested federal-tax module: base STD_DEDUCTION, additionalAgedDeduction(), and the OBBBA seniorDeduction(). See the OBBBA senior-deduction study.
Every figure on this page is computed at build time from QuantCalc's parity-tested calculation modules or a committed dataset — never hand-entered. Reference for research and planning only; not tax, legal, or investment advice.
