For the 2026 tax year, the federal tax brackets for married filing jointly run from 10 percent on the first $24,800 of taxable income up to 37 percent on income above $768,700, with five rates in between. The brackets are progressive, so each rate applies only to the slice of income that falls inside its range, not to every dollar you earn together.
2026 Brackets at a Glance
These thresholds apply to your taxable income, meaning what’s left after you subtract the standard deduction (or itemized deductions) from your gross income:
- 10% on taxable income from $0 to $24,800
- 12% from $24,801 to $100,800
- 22% from $100,801 to $211,400
- 24% from $211,401 to $403,550
- 32% from $403,551 to $512,450
- 35% from $512,451 to $768,700
- 37% on taxable income above $768,700
The IRS set these figures in its annual inflation adjustments for 2026, which reflected changes from the One, Big, Beautiful Bill Act signed into law in July 2025. That legislation made the seven-rate structure from the 2017 Tax Cuts and Jobs Act permanent, so the rates themselves (10, 12, 22, 24, 32, 35, and 37 percent) will carry into future years even as the dollar thresholds continue to shift with inflation.1Internal Revenue Service.

How the Bracket Math Really Works
Landing in the 22 percent bracket does not mean 22 percent of everything you and your spouse earn goes to the IRS. Each bracket is a bucket. It fills at its own rate, and only after it’s full does the next rate start taxing the next dollar.
Say your household has $120,000 in taxable income in 2026. The tax breaks down like this:
- The first $24,800 is taxed at 10% = $2,480
- The next $76,000 (from $24,801 to $100,800) is taxed at 12% = $9,120
- The remaining $19,200 (from $100,801 to $120,000) is taxed at 22% = $4,224
Total federal income tax: $15,824. That’s an effective rate of roughly 13.2 percent, even though your marginal rate (the rate on your last dollar of income) is 22 percent. Every couple’s first $24,800 is taxed identically, whether their total taxable income is $50,000 or $5 million.2Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed
Start with the Standard Deduction
Before any bracket applies, you subtract either the standard deduction or your itemized deductions from your gross income. For 2026, the standard deduction for married couples filing jointly is $32,200, up from $30,000 in 2025.1Internal Revenue Service.

So if the two of you bring in $150,000 gross and claim the standard deduction, only $117,800 gets fed into the bracket table. Overlooking that step is one of the most common reasons people overestimate what they owe. Personal exemptions remain at $0 for 2026.1Internal Revenue Service.

Capital Gains Use a Different Table
Long-term capital gains and qualified dividends do not run through the brackets above. They have their own, lower rate schedule. For 2025 (the most recent year with confirmed thresholds), joint filers pay 0 percent on long-term gains when taxable income stays at or below $96,700, 15 percent up to $600,050, and 20 percent above that.3Internal Revenue Service. Topic No. 409, Capital Gains and Losses The 2026 numbers will be slightly higher after inflation adjustments. Ordinary income (wages, interest, short-term gains, retirement distributions) still uses the seven brackets above.
Extra Taxes That Can Stack on Top
Two additional federal taxes can raise your effective rate beyond what the brackets suggest.
Net Investment Income Tax
If your modified adjusted gross income as a joint filer exceeds $250,000, you owe an additional 3.8 percent on the smaller of your net investment income or the amount by which your MAGI exceeds $250,000. Net investment income covers interest, dividends, capital gains, rental income, and royalties. The $250,000 threshold has never been indexed for inflation, so it captures more households every year.
Alternative Minimum Tax
The AMT is a parallel calculation meant to keep high-income taxpayers from shrinking their regular tax bill too far through deductions and exclusions. For 2026, joint filers get an AMT exemption of $140,200, and the exemption begins phasing out once AMT income crosses $1,000,000.1Internal Revenue Service.

It tends to surface with large state and local tax deductions, incentive stock options, or significant tax-exempt interest.
Credits Come Off After the Brackets
Once you’ve calculated tax using the brackets, credits subtract directly from that figure. The child tax credit is worth up to $2,200 per qualifying child for 2026.4Internal Revenue Service. Child Tax Credit The earned income tax credit can be worth several thousand dollars for lower-income joint filers with children. Both credits phase out at higher incomes, and both are unavailable if you file married filing separately. Credits can move your effective rate well below what the bracket math alone would predict, so check eligibility before assuming the brackets settle your bill.
When Filing Separately Might Beat Filing Jointly
Most couples pay less by filing jointly because the joint brackets are wider and several credits require it. A few situations flip that answer:
- Large medical expenses. Deductible medical costs must exceed 7.5 percent of adjusted gross income. Filing separately keeps only one spouse’s income in the denominator, making it easier to clear the floor. On $50,000 of income, $10,000 in bills is 20 percent of AGI. Combined with a spouse earning $85,000, the same bills are only 7.4 percent of $135,000 and fall just short.
- Income-driven student loan payments. If one spouse repays federal loans under an income-driven plan, filing separately bases the monthly payment on that spouse’s income alone rather than the household total.
- Liability concerns. If you have reason to doubt the accuracy of a joint return your spouse is preparing, filing separately keeps your name off it.
The downsides are real. Filing separately locks you out of the earned income tax credit, the education credits, and the child and dependent care credit, and the standard deduction drops to $16,100 for 2026, half the joint amount. Run the numbers both ways.
The Marriage Penalty at the Top
For most of the bracket table, the joint thresholds are exactly twice the single-filer thresholds, so two comparable earners pay about the same tax whether they marry or not. The symmetry breaks at the top. A single filer in 2026 doesn’t hit 37 percent until income clears $640,600. Two unmarried partners each earning $640,000 stay entirely inside the 35 percent bracket. Marry the same two people, and their combined $1,280,000 sails past the joint 37 percent threshold of $768,700 by more than half a million dollars.1Internal Revenue Service.

The penalty bites hardest when both spouses earn high and roughly equal incomes. When one spouse earns most of the household income, marriage usually produces a bonus instead, because the higher earner’s income gets stretched across wider brackets than a single filer would see. Filing status alone won’t fix it: married filing separately uses even narrower brackets than single filing.
