What Is the 24% Tax Bracket and How Does It Work?

The 24% tax bracket for 2026 applies to taxable income between $105,701 and $201,775 for single filers, between $211,401 and $403,550 for married couples filing jointly, and between $105,701 and $201,750 for heads of household.¹ Only the income that falls inside those ranges is taxed at 24%. Every dollar below the range is taxed at a lower rate, so the total share of your income going to federal tax is always less than 24%, often much less.

What “Marginal” Actually Means

The federal income tax is progressive. Rates stack in layers, and each layer taxes only the income that sits inside it.² Being “in the 24% bracket” means your last dollar of taxable income was taxed at 24%, not that all of it was.

Consider a single filer in 2026 with $120,000 in taxable income:

The first $12,400 is taxed at 10% ($1,240)
$12,401 to $50,400 is taxed at 12% ($4,560)
$50,401 to $105,700 is taxed at 22% ($12,166)
$105,701 to $120,000 is taxed at 24% ($3,432)

Total federal income tax: $21,398. That is an effective rate of about 17.8%. Only $14,300 of this filer’s income was actually taxed at 24%. A raise that nudges you into a higher bracket never leaves you with less take-home pay than before, because only the newly-earned dollars above the threshold get the higher rate.

Taxable Income Is Not the Same as Salary

The bracket thresholds apply to taxable income, which is what remains after you subtract either the standard deduction or your itemized deductions from your gross income. Your paycheck can be well above $105,700 and none of it end up taxed at 24%.

The 2026 standard deduction amounts are $16,100 for single filers, $32,200 for joint filers, and $24,150 for heads of household.¹ A single person earning $120,000 in wages subtracts $16,100 and lands at $103,900 in taxable income. That is below the $105,701 threshold, so not a single dollar is taxed at 24%.

Itemizing can push taxable income lower still if you have significant mortgage interest, state and local taxes (capped at $10,000), or charitable contributions. For most filers at this income level, the standard deduction is larger than what they could itemize.

Using Retirement Contributions to Stay Out of the 24% Range

Pre-tax retirement contributions reduce taxable income dollar for dollar. The 2026 limit for a 401(k) is $24,500, with a $8,000 catch-up for workers 50 and older and a higher $11,250 catch-up for those between 60 and 63.³

A single filer earning $140,000 who contributes $24,500 to a traditional 401(k) brings gross income down to $115,500. After the $16,100 standard deduction, taxable income is $99,400, which sits below the 24% bracket entirely. Every dollar contributed that would have been taxed at 24% saved 24 cents in federal tax.

Traditional IRAs carry a $7,500 limit for 2026, with a $1,100 catch-up at 50 and older.³ If you are covered by a workplace retirement plan, the IRA deduction phases out at higher incomes. For a single filer covered at work, the phase-out runs from $81,000 to $91,000 in modified adjusted gross income, which means most people at 24%-bracket incomes cannot deduct traditional IRA contributions. A Roth IRA or a traditional 401(k) usually makes more sense at this income level.

Capital Gains Are Taxed on a Different Schedule

Long-term capital gains, on assets held more than a year, are taxed under a separate schedule and top out at 15% for most people whose ordinary income lands in the 24% bracket.⁴ Short-term gains, on assets held a year or less, are taxed as ordinary income and get the full 24% treatment.

The Net Investment Income Tax adds a 3.8% surcharge on investment income once modified adjusted gross income passes $200,000 for single filers or $250,000 for joint filers.⁵⁶ Those thresholds are not indexed to inflation. The 24% bracket for joint filers runs to $403,550, so many couples in it clear the $250,000 NIIT line and pay 18.8% on long-term gains instead of 15%. Single filers in the 24% bracket top out at $201,775, so only those near the top of the bracket cross the $200,000 NIIT line.

State Income Tax Still Applies

The 24% figure is federal only. Most states impose their own income tax, with top marginal rates ranging from zero in states without an income tax to more than 13%. A 24% federal bracket earner in a high-tax state can face a combined marginal rate near 37% on the next dollar of ordinary wages. In no-income-tax states, the federal 24% is the whole marginal picture. Any planning around bracket thresholds should account for your state rate too.

The Child Tax Credit at This Income Level

Parents in the 24% bracket generally keep the Child Tax Credit. The credit phases out by $50 for every $1,000 of adjusted gross income above $200,000 for single filers and $400,000 for joint filers. Because the joint 24% bracket starts at $211,401, most married couples in the bracket receive the full credit. Single filers near the top of the bracket see a partial reduction, though the credit does not disappear entirely within the 24% range.

Why the 24% Rate Is Sticking Around

The seven-bracket structure that includes the 24% rate came from the Tax Cuts and Jobs Act of 2017 and was originally set to expire after 2025, at which point the rate would have reverted to 28%. The One, Big, Beautiful Bill Act, enacted in 2025, made the individual rates permanent.¹ The dollar thresholds will keep moving up with inflation each year, but the 24% rate itself is no longer scheduled to change.
