2026 tax brackets for married filing jointly

2026 joint brackets and the tax owed at each boundary

Married couples who file one return together, and qualifying surviving spouses, use the joint schedule. The table adds two columns the plain bracket list leaves out: the tax on each full band, and the running total at the top of each band. The running total tells you the federal income tax on a round taxable income figure without any math.

These figures come from the IRS revenue procedure for 2026 and apply to the joint return filed in the 2027 season. The 2027 married filing jointly brackets are not yet announced; the IRS usually releases them in October or November.

Married filing jointly tax brackets for 2025

If you are still filing, amending or checking a 2025 joint return, use these thresholds instead.

The 2025 joint standard deduction, as raised by the 2025 tax law, was $31,500. Other statuses for 2025 are on the 2025 brackets page.

Do joint brackets double the single brackets?

Up to the 32% bracket, yes, exactly. The top of every joint band from 10% through 32% is twice the matching single figure: $24,800 vs $12,400, $100,800 vs $50,400, and so on up to $512,450 vs $256,225.

The doubling stops at 35%. For a single filer the 35% band runs to $640,600, but for a couple it ends at $768,700, not $1,281,200. Two high earners who marry can therefore pay 37% on income that would have been taxed at 35% if each had filed as single. That is the main remaining marriage penalty in the bracket structure.

The joint standard deduction also doubles the single amount: $32,200 vs $16,100. Compare the full single filer brackets if one of you is deciding whether to marry before or after December 31, since your status on that date controls the whole year.

Joint filers over 65: extra deductions

Couples 65 and older get two separate breaks on top of the $32,200 standard deduction, and both lower the income that reaches the brackets.

• Additional standard deduction: $1,650 for each spouse who is 65 or older, and another $1,650 for each spouse who is blind. Two spouses 65 or older add $3,300. See standard deduction over 65.
• Senior deduction (tax years 2025 to 2028): $6,000 per eligible spouse, $12,000 if both qualify. For 2026 a spouse qualifies if born before January 2, 1962, and has a valid Social Security number. Married couples must file jointly to claim it. It phases out once modified AGI exceeds $150,000 and is claimed on Schedule 1-A whether or not you itemize. Details are on the senior deduction rules page.

Worked example: retired couple, both 66

A couple, both 66, has adjusted gross income of $90,000 in 2026 from pensions, IRA withdrawals and the taxable part of Social Security. Their deductions are $32,200 plus $3,300 for age plus $12,000 senior deduction, a total of $47,500. Taxable income is $42,500. Tax: $2,480 on the first $24,800, plus 12% of $17,700 ($2,124), for $4,604.

Without the senior deduction their taxable income would be $54,500 and the tax $6,044, so that one deduction saves them $1,440. How much of their Social Security counts toward AGI is a separate calculation, covered in tax on Social Security benefits.

MFJ tax brackets in practice: a working couple

Two spouses under 65 each earn $75,000 in wages, $150,000 combined, and take the standard deduction.

1. Combined wages: $150,000 (assume no other income or adjustments).
2. Subtract the $32,200 joint standard deduction: taxable income is $117,800.
3. Tax at the top of the 12% band: $11,600.
4. Add 22% of the $17,000 above $100,800: $3,740.
5. Federal income tax before credits: $15,340. Their marginal rate is 22%; their effective rate on taxable income is about 13%.

If they filed separately instead, each would have $58,900 of taxable income and owe $7,670, which is the same $15,340 total. For couples with similar incomes, joint and separate filing produce the same bracket result; the difference comes from the rules below.

Is it better to file jointly or separately?

For most couples, joint filing gives the same or lower tax. Married filing separately carries several built-in limits for 2026:

• If one spouse itemizes, the other spouse's standard deduction is zero.
• The 35% bracket ends at $384,350 instead of $768,700.
• The SALT deduction cap is $20,200 instead of $40,400.
• The net capital loss deduction is $1,500 instead of $3,000.
• The senior deduction and the deductions for qualified tips and overtime require a joint return if you are married.

Separate returns can still make sense for reasons outside the brackets, such as keeping liability for a spouse's return separate. Run both versions in your software before deciding.
