Federal income tax is not one flat percentage—it uses a bracket system where you pay different rates on different portions of your income

The federal government taxes your income using tax brackets, which means the percentage you pay increases as your income rises. You do not pay one rate on all your money. Instead, your income is divided into chunks, and each chunk is taxed at its own rate. For 2024, the brackets range from 10 percent on the lowest income to 37 percent on the highest, but most people pay an effective rate—the actual percentage of total income that goes to taxes—that is lower than their top bracket.

Your tax bracket depends on your filing status (single, married filing jointly, head of household, or married filing separately) and your total income for the year. The Internal Revenue Service (IRS) updates these brackets annually to account for inflation, so the income ranges that fall into each bracket change from year to year.

Key Takeaways

  • Federal income tax uses seven brackets ranging from 10 percent to 37 percent, and you pay each rate only on the income that falls within that bracket.
  • Your effective tax rate—the actual percentage of your total income that goes to federal taxes—is almost always lower than your highest bracket rate.
  • Tax brackets are adjusted each year for inflation, so the income ranges shift annually.
  • Your filing status (single, married, head of household) determines which bracket table applies to your income.
  • Deductions and credits can lower your taxable income and the amount of tax you owe.

The seven federal tax brackets for 2024

For the 2024 tax year, there are seven federal income tax brackets. The rates are 10 percent, 12 percent, 22 percent, 24 percent, 32 percent, 35 percent, and 37 percent. The income ranges for each bracket differ based on whether you file as single, married filing jointly, head of household, or married filing separately.

For a single filer in 2024, the brackets work like this: 10 percent on income up to $11,600; 12 percent on income from $11,601 to $47,150; 22 percent on income from $47,151 to $100,525; and so on, up to 37 percent on income over $578,100. If you are married filing jointly, the income ranges are wider at each bracket level, which is one reason married couples often pay less total tax than two single filers with the same combined income.

These numbers change each year. The IRS publishes updated brackets in the fall for the following tax year, so you should check the current year's brackets when you file or estimate your taxes.

How the bracket system actually works with an example

Suppose you are a single filer in 2024 with a taxable income of $60,000. You do not pay 22 percent on all $60,000. Instead, you pay 10 percent on the first $11,600, then 12 percent on the next $35,550 (from $11,601 to $47,150), then 22 percent on the remaining $12,850 (from $47,151 to $60,000). Your total federal tax would be about $7,000, which is roughly 11.7 percent of your income—your effective rate.

This is why people often say "I am in the 22 percent bracket" when they really mean that 22 percent is their marginal rate—the rate applied to the last dollar they earned. Your effective rate is what matters for your actual tax bill, and it is always lower than your marginal rate unless you are in the lowest bracket.

Standard deduction and taxable income

Before the tax brackets explore, you subtract the standard deduction from your gross income to arrive at your taxable income. The standard deduction for 2024 is $14,600 for single filers and $29,200 for married couples filing jointly. This means a single person earning $50,000 only pays federal income tax on $35,400 (the amount above the standard deduction).

You can also claim itemized deductions instead of the standard deduction if your deductible expenses (mortgage interest, state and local taxes, charitable donations, and others) add up to more than the standard deduction. Either way, deductions reduce the income that the tax brackets explore to, which lowers your tax bill.

Tax credits reduce your tax bill directly

Tax credits are different from deductions. A deduction reduces your taxable income; a credit reduces the actual tax you owe, dollar for dollar. Common credits include the Earned Income Tax Credit (EITC) for lower-income workers, the Child Tax Credit, and the American Opportunity Credit for education expenses. A $1,000 credit saves you $1,000 in taxes, regardless of your bracket.

Some credits are refundable, meaning if the credit is larger than the tax you owe, the IRS sends you the difference. Others are non-refundable, so they can only reduce your tax to zero but cannot result in a refund. Understanding which credits you may be may have access to to can significantly lower your final tax bill.

Why your effective rate matters more than your bracket

Many people focus on their tax bracket and worry they are paying too much, but your effective rate is the real measure of your tax burden. Someone in the 32 percent bracket might pay an effective rate of only 18 percent because of the way brackets work and because of deductions and credits. Conversely, someone in the 24 percent bracket might have a higher effective rate if they have fewer deductions.

When you see news stories about tax rates or hear politicians discuss tax policy, they are often talking about marginal rates or the top bracket, not what typical people actually pay. Your own tax return shows your effective rate, which is what you actually owe divided by your total income.

State and local income taxes are separate

Federal income tax is only one part of your total tax bill. Most states also charge income tax, and some cities do as well. State and local rates vary widely—some states have no income tax at all, while others charge up to 13 percent. These are separate from federal tax and are calculated on their own brackets and rules.

When you file your federal return, you report your state and local taxes paid as an itemized deduction (up to $10,000 per year under current rules), which can lower your federal taxable income slightly. But state and local taxes are not part of the federal bracket system.

Frequently Asked Questions

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

No. The 37 percent rate applies only to income above the threshold for that bracket. If you are a single filer with $600,000 in taxable income, you pay 37 percent only on the amount above $578,100. The rest of your income is taxed at the lower rates for each bracket below it.

What is the difference between a tax bracket and an effective tax rate?

Your tax bracket (or marginal rate) is the percentage applied to your last dollar of income. Your effective tax rate is your total tax divided by your total income. The effective rate is always lower because you pay lower percentages on the income in lower brackets.

Do tax brackets change every year?

Yes. The IRS adjusts the income ranges for each bracket annually to account for inflation. The rates themselves (10 percent, 12 percent, etc.) stay the same, but the dollar amounts that define each bracket shift upward each year.

Can deductions lower my tax bracket?

Deductions lower your taxable income, which can move you into a lower bracket or reduce the amount of income taxed at your current bracket. They do not change your bracket directly, but they reduce the income the brackets explore to.

Is federal income tax the only tax I owe?

No. You may also owe state income tax, local income tax, self-employment tax (if you are self-employed), and other taxes. Federal income tax is separate from these and uses its own bracket system.
