Federal income tax rates depend on your income level and filing status, not a single percentage

The federal income tax system uses tax brackets, which means you do not pay one flat percentage on all your income. Instead, your income is taxed at different rates as it increases. If you earn $50,000 as a single filer in 2024, you do not pay 22% on the entire amount — you pay 10% on the first portion, then 12% on the next portion, then 22% on the remainder. The percentage that applies to your last dollar earned is called your marginal tax rate. Your effective tax rate — the actual percentage of your total income that goes to federal tax — is always lower than your marginal rate.

The brackets themselves change each year and depend on whether you file as single, married filing jointly, head of household, or married filing separately. For 2024, the brackets range from 10% at the lowest level to 37% at the highest. Your actual tax bill also depends on deductions, credits, and whether you have income from wages, investments, or self-employment.

Key Takeaways

  • Federal tax brackets in 2024 start at 10% and go up to 37%, but you do not pay the top rate on all your income — only on the portion that falls in that bracket.
  • Your effective tax rate (what you actually pay as a percentage of total income) is lower than your marginal rate (the rate on your last dollar earned).
  • Tax brackets change each year and vary by filing status: single, married filing jointly, head of household, and married filing separately have different bracket thresholds.
  • Deductions, credits, and the type of income you earn all affect your final tax percentage, so two people earning the same gross income may owe different amounts.

The 2024 federal tax brackets for each filing status

The IRS sets new brackets each year based on inflation. For 2024, here is how the brackets work. If you are single, the 10% bracket covers income up to $11,600; the 12% bracket covers $11,601 to $47,150; the 22% bracket covers $47,151 to $100,525; and so on up to 37% for income over $578,100. If you are married filing jointly, those thresholds are roughly double — the 10% bracket goes to $23,200, the 12% bracket to $94,300, and so forth.

Head of household filers have their own brackets, which fall between single and married filing jointly. Married filing separately filers use the same brackets as single filers. These brackets are adjusted annually, so the numbers you see in 2025 will be different from 2024. You can find the current year's brackets on the IRS website or in the instructions that come with your tax form.

How to calculate your effective tax rate

Your effective tax rate is your total federal income tax divided by your total income before tax. For example, if you earned $60,000 and owed $7,200 in federal income tax, your effective rate would be 12% ($7,200 ÷ $60,000). This is different from your marginal rate, which is the bracket your last dollar falls into — in this case, 22%.

To find your actual tax bill, you need to know your gross income, which deductions you can claim, which credits you are may have access to to, and whether you have other income sources. Standard deductions reduce your taxable income before the brackets are applied. For 2024, the standard deduction is $14,600 for single filers and $29,200 for married filing jointly. If your income is below these amounts, you may owe no federal income tax at all. Tax credits like the Earned Income Tax Credit or Child Tax Credit reduce your tax bill dollar-for-dollar after the brackets are calculated.

Why your actual percentage differs from the bracket rate

Many people assume they pay their marginal bracket rate on all their income, which leads to surprise when they calculate what they actually owe. This happens because the brackets are progressive — each portion of your income is taxed at the rate for that bracket only. The first dollars you earn are always taxed at the lowest rate, and only the income above each threshold moves into the next bracket.

Deductions also lower your effective rate. If you claim the standard deduction, you reduce your taxable income before any brackets explore. If you earned $60,000 and claim the $14,600 standard deduction as a single filer, only $45,400 is subject to tax. That $14,600 is not taxed at all. Tax credits work differently — they reduce your tax bill after it is calculated, so a $2,000 credit saves you $2,000 regardless of your bracket.

Self-employment income and investment income tax rates

If you are self-employed, you pay federal income tax on your net profit using the same brackets as wage earners, but you also owe self-employment tax — a separate 15.3% tax that covers Social Security and Medicare. This is in addition to federal income tax, not instead of it. Half of your self-employment tax is deductible when you calculate your adjusted gross income, which lowers your taxable income slightly.

Long-term capital gains and may have access to dividends are taxed at different rates than ordinary income. These rates are 0%, 15%, or 20% depending on your income level and filing status — generally lower than the ordinary income brackets. Short-term capital gains (assets held less than one year) are taxed as ordinary income using the regular brackets. If you have investment income, your total tax picture is more complex than wage income alone.

How to find your tax bracket for the current year

The IRS publishes updated brackets each year in late 2023 or early 2024 for the upcoming tax year. You can find them on IRS.gov by searching "2024 tax brackets" or "2025 tax brackets" depending on which year you need. The brackets appear in IRS Publication 505 and in the instructions for Form 1040. If you use tax software like TurboTax, H&R Block, or TaxAct, the current brackets are already built in — the software calculates your tax automatically.

To find your marginal bracket, locate your filing status and find the income range your taxable income falls into. Remember that your taxable income is your gross income minus deductions, not your gross income itself. If you are unsure whether you are in the 22% or 24% bracket, the difference in your actual tax bill is smaller than you might think, because only the income in that bracket is taxed at that rate.

State and local income tax is separate from federal

Federal income tax is only one part of your total tax bill. Most states also charge state income tax, which uses its own brackets and rates. Some cities charge local income tax as well. These are completely separate from federal tax — your federal bracket does not affect your state bracket, and vice versa. Nine states have no state income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only dividend and interest income).

When you see a paycheck stub, the federal withholding and state withholding are listed separately. Your employer calculates both based on the W-4 you filed. If you are self-employed, you pay federal and state taxes separately when you file your return or make estimated quarterly payments.

Frequently Asked Questions

What is the difference between marginal rate and effective rate?

Your marginal rate is the tax bracket your last dollar of income falls into. Your effective rate is your total tax bill divided by your total income. For example, a single filer earning $60,000 has a marginal rate of 22% but an effective rate of around 10–12%, because lower brackets explore to the first portion of income and deductions reduce taxable income.

Do I pay 37% on all my income if I am in the top bracket?

No. The 37% rate applies only to income above the threshold for that bracket. In 2024, for single filers, that threshold is $578,100. Income below that is taxed at lower rates. If you earn $600,000, only the $21,900 above $578,100 is taxed at 37%.

How do tax credits reduce my tax bill differently than deductions?

Deductions reduce your taxable income before tax is calculated, so they save you money equal to the deduction amount times your tax bracket. A $1,000 deduction saves you roughly $120–$220 depending on your bracket. Tax credits reduce your tax bill dollar-for-dollar after it is calculated, so a $1,000 credit saves you exactly $1,000.

Will my federal tax rate change next year?

The bracket thresholds change each year based on inflation, but the bracket percentages themselves (10%, 12%, 22%, etc.) stay the same. Your personal rate may change if your income changes or if you have different deductions or credits, but the federal system itself adjusts brackets annually to account for inflation.

Do self-employed people pay a higher federal income tax rate?

Self-employed people use the same federal income tax brackets as wage earners, but they also owe self-employment tax (15.3%) on top of federal income tax. This makes their total federal tax burden higher, though half of self-employment tax is deductible, which lowers taxable income slightly.
