For tax year 2026, a married couple filing a joint federal return runs their taxable income through seven brackets: 10% on the first $24,800, 12% up to $100,800, 22% up to $211,400, 24% up to $403,550, 32% up to $512,450, 35% up to $768,700, and 37% on anything above that.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Only the income that falls inside a given band is taxed at that band’s rate, so the top rate on your return is almost never the rate you actually pay overall.
2026 Married Filing Jointly Bracket Table
These thresholds apply to taxable income, meaning gross income minus adjustments and either the standard deduction or your itemized deductions. They come from the IRS inflation adjustments under Revenue Procedure 2024-40, as amended by the One, Big, Beautiful Bill signed into law in 2025.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
- 10% on taxable income up to $24,800
- 12% on income from $24,801 to $100,800
- 22% on income from $100,801 to $211,400
- 24% on income from $211,401 to $403,550
- 32% on income from $403,551 to $512,450
- 35% on income from $512,451 to $768,700
- 37% on income above $768,700
How the Brackets Turn Into an Actual Tax Bill
Landing “in the 24 percent bracket” doesn’t mean 24 percent of your income goes to the IRS. Federal rates are marginal, so each bracket only touches the dollars inside it.
Consider a couple with $217,800 in taxable income. Their tax stacks up in layers. The first $24,800 is taxed at 10%, which is $2,480. The next slice from $24,801 to $100,800 is taxed at 12%, which is $9,120. The slice from $100,801 to $211,400 is taxed at 22%, which is $24,332. Only the last $6,400 above $211,400 hits the 24% band, adding $1,536. The total comes to roughly $37,468.
Their marginal rate is 24% because that’s the rate on their next dollar earned. Their effective rate is $37,468 divided by $217,800, or about 17.2%. A raise doesn’t reprice all their earlier income; it only moves the new dollars into the next tier.
Getting to Taxable Income
Before the bracket table applies, you have to work down to taxable income. Start with gross income (wages, interest, dividends, freelance earnings, rental income, and so on), subtract above-the-line adjustments like traditional IRA contributions or student loan interest to get adjusted gross income, then subtract either the standard deduction or your itemized deductions.
For 2026, the standard deduction for married filing jointly is $32,200.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Itemizing helps only if your combined mortgage interest, state and local taxes (capped at $10,000), charitable gifts, and other eligible expenses beat that figure. A couple earning $250,000 in gross income and taking the standard deduction has $217,800 in taxable income, the same figure used in the example above.
Senior Bonus Deduction
The One, Big, Beautiful Bill added a $6,000 deduction for taxpayers age 65 or older, effective for tax years 2025 through 2028. It stacks on top of the existing additional standard deduction for seniors. When both spouses are 65 or older, the couple can claim $12,000 in new deductions combined.2Internal Revenue Service. One, Big, Beautiful Bill Act – Tax Deductions for Working Americans and Seniors It phases out for joint filers with modified AGI above $150,000, requires a joint return, and is available even if you itemize.
Long-Term Capital Gains Use a Different Schedule
Investments held longer than a year, along with qualified dividends, don’t run through the ordinary brackets. For 2026, joint filers face three tiers:
- 0% on taxable income up to $98,900
- 15% on income from $98,901 to $613,700
- 20% on income above $613,700
The 0% tier is a true zero. A retired couple living mostly on long-term gains and qualified dividends, with taxable income under $98,900, owes no federal tax on those gains. Taxable income here includes everything, though, so wages and retirement distributions can push gains into the 15% or 20% band.
Surtaxes That Stack on Top at Higher Incomes
The bracket table isn’t the whole picture for higher-earning couples. Two surtaxes and one parallel calculation can apply on top of the regular rates.
Net Investment Income Tax
A 3.8% tax hits the lesser of your net investment income or the amount your modified AGI exceeds $250,000 for joint filers.3Office of the Law Revision Counsel. 26 USC 1411 – Imposition of Tax Net investment income covers interest, dividends, capital gains, rental income, and royalties. The $250,000 threshold is set by statute and doesn’t adjust for inflation, so more couples cross it each year.
Additional Medicare Tax
An extra 0.9% Medicare tax applies to wages and self-employment income above $250,000 for joint filers.4Internal Revenue Service. Questions and Answers for the Additional Medicare Tax That threshold also doesn’t adjust for inflation. Employers start withholding the extra 0.9% once an individual employee’s wages pass $200,000, so joint filers whose combined wages cross $250,000 may need to reconcile at filing time.
Alternative Minimum Tax
The alternative minimum tax runs a parallel calculation that disallows certain deductions and applies a flatter rate structure. For 2026, joint filers get an AMT exemption of $140,200, which begins to phase out when AMT income exceeds $1,000,000.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Most couples never owe AMT. Those most exposed exercise incentive stock options, claim large state and local tax deductions, or have significant miscellaneous deductions, typically in the roughly $250,000 to $600,000 income range.
When Joint Filing Helps or Hurts
Joint filing almost always beats married filing separately. Separate filers lose access to several credits and deductions, and their bracket thresholds are exactly half the joint amounts, so there’s no mathematical advantage for ordinary income.5Internal Revenue Service. Filing Status
The comparison that matters more is joint filing against what two unmarried people would owe as single filers. Every joint bracket from 10% through 35% is exactly double the single-filer threshold, so a couple with two equal $100,000 salaries hits the same combined brackets whether married or not. The structural marriage penalty shows up only at the top: the 37% bracket kicks in at $768,700 for joint filers, less than double the $640,600 threshold for single filers. Couples above that range pay more married than they would as two single filers.
When one spouse earns much more than the other, joint filing usually creates a marriage bonus. The higher earner’s income gets spread across the joint brackets, pulling some of it out of a higher rate. A couple where one spouse earns $300,000 and the other earns $40,000 typically owes less jointly than the higher earner would owe as a single filer.
Who Can File Jointly
Marital status is fixed on December 31. If you were legally married on the last day of the tax year, the IRS treats you as married for the whole year, even if the wedding was on New Year’s Eve.6Office of the Law Revision Counsel. 26 USC 7703 – Determination of Marital Status Living apart doesn’t change that. You’re still married unless a court has issued a final divorce decree or decree of separate maintenance before year-end.
If one spouse dies during the year, the surviving spouse can still file a joint return for that year, as long as they haven’t remarried before year-end and no executor files a separate return for the decedent.7Office of the Law Revision Counsel. 26 USC 6013 – Joint Returns of Income Tax by Husband and Wife
One boundary catches people off guard. If one spouse is a nonresident alien, the couple generally cannot file jointly unless they make a special election to treat the nonresident spouse as a U.S. resident for tax purposes. That election is binding until formally revoked, and it means the foreign spouse’s worldwide income becomes reportable on the U.S. return.7Office of the Law Revision Counsel. 26 USC 6013 – Joint Returns of Income Tax by Husband and Wife
Filing jointly also creates joint and several liability. Both spouses are responsible for the full tax owed, not just their own share. If one spouse underreports income, the other can be on the hook for the balance unless they qualify for innocent spouse relief. Worth thinking through before checking the joint box in any situation where you aren’t confident about your spouse’s financial disclosures.
