How it works

The enhanced deduction applies for tax years 2025–2028; this calculator uses 2026. Under Schedule 1-A Part V, calculate the income reduction for each eligible person before adding the two amounts on a joint return.

Per eligible person = max(0, $6,000 − 0.06 × max(0, MAGI − threshold)) Threshold = $150,000 for a joint return; $75,000 otherwise Total = your eligible amount + spouse’s eligible amount

Married filing separately is ineligible for the enhanced deduction. Calculations retain full precision; displayed dollars are rounded to cents. This is not a calculation of tax owed or refundable tax savings.

Rev. Proc. 2025-32 sets the separate 2026 age-based standard deduction addition at $2,050 for single and head-of-household filers, or $1,650 for married filers and qualifying surviving spouses, per qualifying person. It is available only when eligible to use the standard deduction and choosing it. The display excludes the base standard deduction and blindness additions.

Worked examples

Single filer with $90,000 MAGI

One eligible senior: $6,000 − ($90,000 − $75,000) × 6% = $5,100. If taking the standard deduction, the separate age addition is $2,050.

Two eligible spouses with $200,000 MAGI

Each spouse gets $6,000 − ($200,000 − $150,000) × 6% = $3,000. The enhanced total is $6,000; the separate age-based standard deduction addition is $3,300.

Frequently asked questions

Can I claim the enhanced deduction if I itemize?
Yes. Itemizing does not prevent this deduction. It does prevent the separate age-based standard deduction addition shown here.
When is the enhanced deduction fully phased out?
At $175,000 MAGI for eligible non-joint filers or $250,000 for joint filers. On a joint return, each eligible spouse has the same income reduction.
Does turning 65 on January 1, 2027 count for 2026?
Yes. For tax purposes, you reach age 65 the day before your birthday. Generally, you must be born before January 2, 1962. A deceased taxpayer must have reached 65 before death.
Does each spouse need an SSN?
Each spouse claiming an enhanced amount needs an SSN valid for employment, issued by the return due date including extensions. One eligible spouse can claim their amount even if the other does not qualify.
Is this only for people receiving Social Security?
No. Eligibility is based on age, filing status, SSN and income, not receipt of Social Security benefits. It does not itself make those benefits tax-free.
