Your federal tax rate depends on your income and filing status, not on a single number the government assigns to you

The federal government does not give you one tax rate. Instead, it uses a tax bracket system: you pay different percentages on different portions of your income. The highest percentage you pay is called your marginal tax rate. The average percentage you pay across all your income is called your effective tax rate. Most people mean effective rate when they ask "what is my tax rate," because that is the real percentage of your total income that goes to federal taxes.

Your bracket depends on two things: how much you earned in the tax year, and whether you file as single, married filing jointly, married filing separately, or head of household. The IRS publishes new bracket tables every year because they adjust for inflation. For the 2024 tax year (filed in 2025), there are seven federal brackets ranging from 10 percent to 37 percent, but almost no one pays 37 percent on all their income—that rate applies only to income above a certain threshold.

Key Takeaways

  • Your marginal tax rate is the percentage you pay on your last dollar of income; your effective rate is the average percentage across all your income.
  • Federal tax brackets change every year and depend on your filing status (single, married filing jointly, head of household, or married filing separately).
  • You can estimate your effective rate by looking up your income against the IRS tax bracket table for your filing status and year.
  • Your actual federal tax rate on your return may be lower than your bracket suggests because of deductions, credits, and other adjustments.
  • The IRS website publishes current bracket tables, and the Form 1040 instructions include a tax table for most filers.

How tax brackets work: an example

Suppose you are single and earned $60,000 in 2024. You do not pay 22 percent (your bracket) on all $60,000. Instead, you pay 10 percent on the first portion, 12 percent on the next portion, and 22 percent only on the portion above a certain threshold. The IRS calls these thresholds "taxable income limits."

For a single filer in 2024, the 22 percent bracket starts at $47,150. So on $60,000 of income, you would pay 10 percent on the first $11,600, then 12 percent on the next $35,550, then 22 percent on the remaining $12,850. Your total federal tax would be around $7,000, which is roughly 11.7 percent of your $60,000 income—that is your effective rate. Your marginal rate is 22 percent because that is the rate on your last dollar.

Where to find the current tax brackets for your situation

The IRS publishes tax bracket tables on its website at irs.gov. Look for "2024 Tax Brackets" (or the current year) and select the table that matches your filing status. The tables show the income ranges for each bracket and the tax rate that applies to each range.

If you file using Form 1040, the instructions that come with the form include a tax table. You find your taxable income in the left column and your filing status across the top, then read across to find your tax. This table does the bracket math for you.

You can also use the IRS Tax Withholding Estimator on irs.gov if you want to estimate what you will owe or receive as a refund. It asks about your income, deductions, and credits, then shows you an estimate of your federal tax liability.

The difference between your bracket and what you actually owe

Your marginal bracket is not the same as your actual tax bill. Several things can lower the amount you owe: the standard deduction (a flat amount you can subtract from your income before calculating tax), itemized deductions if you choose those instead, and tax credits like the Earned Income Tax Credit or Child Tax Credit.

For example, if you earned $60,000 but took the standard deduction of $14,600 (for a single filer in 2024), your taxable income would be $45,400, not $60,000. That moves you into a lower bracket. Tax credits are even more powerful because they reduce your tax dollar-for-dollar, not just your income.

This is why two people with the same salary can owe very different amounts of federal tax. One might have children, a mortgage, or other circumstances that trigger credits or deductions the other does not have.

How to calculate your effective tax rate

Once you know your federal tax liability (the amount you owe), divide it by your total income for the year. For example, if you owed $7,000 in federal tax on $60,000 of income, your effective rate is 7,000 ÷ 60,000 = 0.1167, or about 11.7 percent.

Your effective rate is almost always lower than your marginal rate because of how brackets work. It is the number that tells you what percentage of your actual earnings went to federal income tax.

Why your withholding might not match your actual rate

If you work as an employee, your employer withholds federal tax from each paycheck based on the W-4 form you filled out. That withholding is an estimate. It might be too high, too low, or roughly correct depending on your situation.

If you have two jobs, a spouse who also works, significant investment income, or major life changes during the year, your withholding might not match what you actually owe. That is why some people get refunds and others owe money when they file. The IRS Tax Withholding Estimator can help you adjust your W-4 mid-year if you realize your withholding is off.

Self-employed and business income: a different calculation

If you are self-employed, you pay federal income tax on your net profit (income minus business expenses), but you also pay self-employment tax (Social Security and Medicare), which is separate from your income tax rate. Self-employment tax is 15.3 percent on 92.35 percent of your net earnings, and it is in addition to your federal income tax bracket.

You report self-employment income on Schedule C and calculate self-employment tax on Schedule SE. The combination of income tax plus self-employment tax is what you owe. A tax professional or tax software can help you calculate this correctly because the math is more complex than for W-2 employees.

Frequently Asked Questions

Is my tax bracket the same as my tax rate?

No. Your tax bracket is the highest rate you pay, applied only to income above a certain threshold. Your effective tax rate is the average percentage of your total income that goes to federal tax. Most people pay an effective rate well below their bracket because of how the bracket system works.

Do I pay the same federal tax rate on all my income?

No. You pay 10 percent on the first portion of your income, then 12 percent on the next portion, and so on, depending on your filing status and total income. Only the income in your highest bracket is taxed at your marginal rate.

Can my effective tax rate be zero even if I earned income?

Yes. If your income is below the standard deduction for your filing status, you owe no federal income tax. You may still need to file to claim refundable credits like the Earned Income Tax Credit, which can result in a refund even if you owe zero tax.

Where do I find my actual federal tax rate from last year?

Look at your completed Form 1040 from last year. Divide the total tax (line 24) by your total income (line 9). That is your effective rate. You can also look at your tax return transcript from the IRS, which shows the same information in a different format.

Does my state income tax count toward my federal tax rate?

No. Federal and state income taxes are separate. Your federal tax rate applies only to federal income tax. State rates vary by state and are calculated independently. Some states have no income tax at all.
