Federal income tax rates are set by tax brackets, not a single percentage

The federal government does not charge everyone the same tax rate. Instead, your income is divided into brackets, and each bracket has its own rate. The rate goes up as your income goes higher — this is called a progressive tax system. For 2024, there are seven brackets ranging from 10% to 37%, depending on how much you earn and your filing status.

The brackets themselves change every year because they are adjusted for inflation. The IRS publishes new brackets each January. This means the income ranges that fall into each bracket shift annually, but the percentage rates themselves have stayed the same since 2017.

A common mistake is thinking that if you move into a higher bracket, all your income gets taxed at that rate. That is not how it works. Only the income that falls within each bracket is taxed at that bracket's rate. The rest stays taxed at the lower rates.

Key Takeaways

  • Federal tax brackets for 2024 range from 10% to 37%, and the income ranges for each bracket depend on whether you file as single, married filing jointly, head of household, or married filing separately.
  • Only the income within each bracket is taxed at that bracket's rate — earning more money and moving to a higher bracket does not raise the tax rate on your entire income.
  • The IRS adjusts bracket income ranges every January for inflation, so the thresholds change yearly even though the percentage rates have remained the same since 2017.
  • Your actual federal tax bill also depends on deductions, credits, and other factors beyond just your bracket rate.

The seven federal tax brackets and their 2024 rates

For the 2024 tax year, the brackets are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Each bracket applies to a specific range of income, and that range depends on your filing status. A single filer, a married couple filing jointly, and a head of household all have different income ranges for the same bracket.

The lowest bracket (10%) applies to the first portion of income for everyone. For a single filer in 2024, that is income from $0 to $11,600. For married couples filing jointly, it is $0 to $23,200. Once your income exceeds that threshold, the next portion is taxed at 12%, and so on up the brackets.

The highest bracket (37%) only applies to income above a certain threshold. For single filers in 2024, that threshold is $578,100. For married filing jointly, it is $693,750. Very few taxpayers reach this bracket.

How tax brackets actually work with an example

Suppose you are a single filer with $60,000 in income in 2024. You do not pay 22% on all $60,000. Instead, your income is taxed like this: the first $11,600 is taxed at 10%, the next portion up to $47,150 is taxed at 12%, and the remaining income up to $60,000 is taxed at 22%. Only that last chunk is at the higher rate.

This is why moving into a higher bracket does not mean a sudden jump in your total tax bill. Your tax rate increases only on the income that falls into the new bracket, not on everything you earn. This is called your marginal tax rate — the rate you pay on your last dollar of income.

Your effective tax rate is different. It is your total federal income tax divided by your total income. For most people, the effective rate is lower than the marginal rate because lower brackets apply to the earlier portions of income.

Why brackets change every year

The IRS adjusts tax brackets annually to account for inflation. This means the income ranges shift upward each year, but the percentage rates stay the same. Without this adjustment, inflation would push more people into higher brackets even if their real income (adjusted for inflation) had not changed. This is called bracket creep.

The adjustment factor for 2024 was based on inflation data from 2023. The 2025 brackets will be announced in late 2024 and will reflect inflation from 2024. You can find the current year's brackets on the IRS website or from a tax preparer.

Standard deduction and how it affects your bracket

Before you are taxed on any income, you can subtract the standard deduction. This is a set amount that reduces your taxable income. For 2024, the standard deduction is $14,600 for single filers and $29,200 for married couples filing jointly. If your income is below the standard deduction, you owe no federal income tax.

This means your actual taxable income — the amount that gets divided into brackets — is lower than your total income. If you earn $50,000 as a single filer, your taxable income is $50,000 minus $14,600, or $35,400. That $35,400 is what gets placed into the brackets.

Credits and deductions that lower your tax bill further

Your bracket rate and standard deduction are only part of your federal tax calculation. Tax credits reduce your tax bill dollar-for-dollar. Tax deductions reduce your taxable income before it is placed into brackets. Common credits include the Earned Income Tax Credit and the Child Tax Credit. Common deductions include mortgage interest and charitable donations.

Because of these credits and deductions, two people in the same tax bracket can owe very different amounts of federal tax. Your actual tax bill depends on your full financial picture, not just which bracket your income falls into.

Self-employment and additional taxes

If you are self-employed, you pay federal income tax using the same brackets as everyone else. However, you also pay self-employment tax, which covers Social Security and Medicare. This is a separate calculation and is not part of your income tax bracket.

Self-employment tax is 15.3% on 92.35% of your net self-employment income. This is in addition to your federal income tax. So a self-employed person with income in the 22% bracket actually pays 22% federal income tax plus the self-employment tax on top of that.

Frequently Asked Questions

Does moving to a higher tax bracket mean I will take home less money?

No. Only the income that falls into the higher bracket is taxed at that rate. If you earn an extra $1,000 and it pushes you into the 24% bracket, you pay 24% on that $1,000, not on your entire income. You still take home more money overall, even after the higher tax on that portion.

What is the difference between my tax bracket and my effective tax rate?

Your tax bracket (also called marginal rate) is the percentage you pay on your last dollar of income. Your effective tax rate is your total federal tax divided by your total income. The effective rate is usually lower because earlier portions of your income are taxed at lower rates. If you earn $60,000 and owe $7,000 in federal tax, your effective rate is about 11.7%, even though your marginal bracket is 22%.

Do state income taxes use the same brackets as federal?

No. State income tax brackets are set by each state and are completely separate from federal brackets. Some states have no income tax at all. Your state tax bill is calculated independently using your state's own brackets, rates, and rules. Federal and state taxes are both withheld from your paycheck if you live in a state with income tax.

When do the 2025 tax brackets come out?

The IRS typically announces the next year's tax brackets in late October or early November. For 2025, the brackets were announced in October 2024. You can find them on the IRS website or from a tax professional. The brackets are based on inflation data from the previous year.

Can I reduce my federal income tax by choosing a different filing status?

Your filing status affects which bracket ranges apply to your income, so it does change your tax calculation. Married filing jointly usually results in a lower tax bill than filing separately. Head of household has different brackets than single. However, you must use the filing status that matches your actual situation — you cannot choose based solely on tax savings.
