Federal income tax rates are not one number — they're a series of brackets that increase as your income rises

The federal government taxes income using a progressive tax system. This means you don't pay one flat percentage on all your earnings. Instead, your income is divided into chunks, and each chunk is taxed at a different rate. The rates for 2024 range from 10% on the lowest bracket to 37% on the highest. The rate that applies to your last dollar of income is called your marginal tax rate; your effective tax rate is the average percentage you pay on all your income combined.

The specific brackets and rates change each year because they're adjusted for inflation. Your filing status matters too — single filers, married filing jointly, and head of household each have different bracket thresholds. A single person earning $50,000 pays tax at different rates than a married couple earning the same amount.

Key Takeaways

  • Federal tax brackets in 2024 range from 10% to 37%, and you pay the lowest rate only on income within the lowest bracket, not on all your income.
  • Your marginal rate is the percentage applied to your last dollar earned; your effective rate is your total tax divided by total income, which is always lower than your marginal rate.
  • Tax brackets shift each year for inflation, and your filing status (single, married, head of household) determines which bracket thresholds apply to you.
  • Deductions and credits reduce the income that gets taxed or the tax you owe, which is why two people with the same salary can owe very different amounts.

How the bracket system actually works

Here's a concrete example. For 2024, a single filer's brackets are roughly: 10% on income up to $11,600, then 12% on income from $11,601 to $47,150, then 22% on income from $47,151 to $100,525, and so on up to 37% on income over $578,100. If you earn $60,000, you don't pay 22% on all of it. You pay 10% on the first $11,600, 12% on the next $35,550, and 22% only on the remaining $12,850.

This is why your effective tax rate is always lower than your marginal rate. Someone earning $60,000 might have a marginal rate of 22% but an effective rate closer to 10% or 11%, because most of their income was taxed at lower rates. The IRS publishes tax tables and worksheets each year showing the exact brackets for each filing status.

What reduces the income that gets taxed

Your income doesn't go straight into the tax brackets. First, certain amounts are subtracted. The standard deduction is a flat amount that reduces your taxable income — for 2024, it's $14,600 for single filers and $29,200 for married couples filing jointly. If you earn $60,000 and take the standard deduction, only $45,400 is actually taxed.

Some people itemize deductions instead, listing specific expenses like mortgage interest, property taxes, or charitable donations. You choose whichever method gives you the larger deduction. Beyond deductions, tax credits work differently — they reduce the tax you owe dollar-for-dollar, not the income being taxed. A $1,000 credit saves you $1,000 in tax; a $1,000 deduction saves you roughly $220 if you're in the 22% bracket.

Why your paycheck doesn't match the tax brackets

Your employer withholds federal income tax from each paycheck based on a formula tied to your W-4 form. The withholding is an estimate meant to land close to what you'll actually owe when you file your return. If you claim too many allowances on your W-4, too little is withheld and you'll owe money in April. If you claim too few, too much is withheld and you'll receive a refund.

The withholding system uses the same brackets and rates, but it applies them to your pay period (weekly, biweekly, monthly) rather than your annual income. This is why someone earning $3,000 per week might see a different withholding percentage than someone earning $60,000 per year, even though their annual income is similar.

Self-employment and additional taxes

If you're self-employed, you owe both income tax and self-employment tax, which covers Social Security and Medicare. Self-employment tax is 15.3% on 92.35% of your net self-employment income — roughly 14.1% of your actual net earnings. This is in addition to income tax. You can deduct half of your self-employment tax when calculating your adjusted gross income, which reduces the income subject to income tax brackets.

Self-employed people also make quarterly estimated tax payments rather than having an employer withhold. The IRS provides Form 1040-ES to calculate what you owe each quarter.

State and local taxes are separate from federal rates

Federal income tax brackets apply only to federal tax. Your state may have its own income tax with its own brackets and rates, or it may have no income tax at all. Nine states — Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (on dividends and interest only) — don't tax income. Other states' rates range from roughly 1% to over 13%, and they have their own bracket systems.

Local taxes in some cities and counties add another layer. New York City, for example, has a local income tax on top of state and federal taxes. Your total tax burden depends on where you live and work, not just on federal brackets.

How to find the current year's brackets

The IRS publishes updated tax brackets each January on its website (irs.gov). You can search for "2024 tax brackets" or "2025 tax brackets" to find the current rates for your filing status. The brackets are also included in the instructions for Form 1040 and in IRS Publication 505. Tax software and payroll systems update automatically each year, so if you use either, you don't need to look them up yourself.

If you're calculating your own withholding or estimated taxes, the IRS Tax Withholding Estimator (available on irs.gov) walks you through questions about your income, deductions, and credits to suggest the right withholding amount for your situation.

Frequently Asked Questions

Does everyone in the same tax bracket pay the same percentage?

No. Two people in the 22% bracket pay 22% only on income within that bracket. Their effective rates differ based on how much income falls into lower brackets, and credits or deductions they claim. Someone earning $50,000 and someone earning $100,000 are both in the 22% bracket, but they owe different amounts.

If I get a raise, will I lose money because I move to a higher tax bracket?

No. Only the income above the bracket threshold is taxed at the higher rate. If a raise pushes you from the 12% bracket into the 22% bracket, you still pay 12% on all income up to the bracket line. Only the amount above that line is taxed at 22%. You always come out ahead with a raise.

Why do I owe taxes if my employer already withheld?

Withholding is an estimate based on your W-4 answers and pay frequency. If your actual tax liability (after deductions and credits) is higher than what was withheld, you owe the difference. This often happens if you have multiple jobs, significant investment income, or claimed too many allowances on your W-4.

Are capital gains taxed at the same rates as wages?

No. Long-term capital gains (assets held over a year) have their own lower brackets: 0%, 15%, or 20% depending on your income level. Short-term gains (held under a year) are taxed as ordinary income using the regular brackets. This is why investment income can be taxed differently than salary.
