2026 Senior Deduction
Standard Deduction Over 65 Married Filing Separately (2026)
This is the one filing status the senior deduction is not available for. Filing separately the amount is $0 however old you are, so the useful question is what the same household income would be worth on a joint return. That is what the table below shows.
Deduction by MAGI, married filing separately
Combined household MAGI. The joint columns assume you elect married filing jointly instead, which is what makes the deduction available in the first place.
| Combined MAGI | Filing separately | Jointly, one 65+ | Jointly, both 65+ |
|---|---|---|---|
| $50,000 | $0 | $6,000 | $12,000 |
| $75,000 | $0 | $6,000 | $12,000 |
| $100,000 | $0 | $6,000 | $12,000 |
| $125,000 | $0 | $6,000 | $12,000 |
| $150,000 | $0 | $6,000 | $12,000 |
| $175,000 | $0 | $4,500 | $10,500 |
| $200,000 | $0 | $3,000 | $9,000 |
| $225,000 | $0 | $1,500 | $7,500 |
| $250,000 | $0 | $0 | $6,000 |
The bold row is $150,000, where the phase-out begins on a joint return. Available for tax years 2025 through 2028; a valid Social Security number is required for each qualifying person. Estimates only, not tax advice.
What this means for married filing separately
The third column is the cost of the election, and it is at its largest well before the phase-out does anything. A couple who are both 65 or older with combined MAGI under $150,000 are giving up the full $12,000 by filing separately, and the figure only starts falling once income passes the joint threshold. Filing separately does not halve the deduction or shift it to the higher earner. It removes it.
That said, the deduction is one line in a larger decision. Separate returns are usually chosen for reasons that have nothing to do with it, such as keeping liability apart or protecting an income-driven student loan repayment calculation, and those reasons can still win. What the table gives you is the price tag: read your combined MAGI down the left, and the difference between the second and fourth columns is what the separate election costs your household in deduction for the year.
Other filing statuses
To enter your own age and income rather than reading a row, the senior deduction calculator runs the same figures live. If you are still drawing a salary past 65, 2026 take-home pay shows what federal tax and FICA leave from it, which is the income this phase-out is measured against.
Frequently asked questions
Can married filing separately claim the senior deduction?
Generally no. The deduction is not available on a married filing separately return, so the amount is $0 even if both of you are 65 or older. The existing age-65 extra standard deduction is a different provision and is not what this page is about.
How much does filing separately cost us?
Up to $12,000 of deduction if you are both 65 or older, or $6,000 if one of you is, assuming your combined MAGI is under the $150,000 joint threshold. Above that the joint amount tapers by 6 cents per dollar, so the gap narrows as income rises and closes entirely at $350,000.
What if we file separately and only one of us is 65?
The deduction is still unavailable to both of you. On a joint return that same household would start from $6,000 for the qualifying spouse, measured against $150,000 of joint MAGI.
Should we switch to filing jointly?
That is a full-return question rather than a deduction question, but this page gives you one side of it. Compare the fourth column against whatever the separate returns are saving you elsewhere. Note also that a valid Social Security number is required for each qualifying person, and the deduction only runs for tax years 2025 through 2028.
