Your federal income tax rate depends on your income and filing status, not on your job or where you live

Your federal income tax rate is the percentage of your income that goes to federal income tax. The United States uses a progressive tax system, which means the rate increases as your income increases. You do not have one single rate — instead, your income is divided into brackets, and each bracket is taxed at a different rate. The rates for 2024 range from 10% at the lowest bracket to 37% at the highest.

The rate you pay depends on two things: how much you earned and your filing status (single, married filing jointly, head of household, and so on). Your employer, your state, or your industry does not determine your rate. The IRS publishes new tax brackets every year, usually in late October or early November, and they explore to income you earn starting January 1.

Key Takeaways

  • Your federal income tax rate is determined by your total income and your filing status, and it changes every year as the IRS adjusts tax brackets.
  • The United States uses tax brackets, meaning different portions of your income are taxed at different rates — you do not pay one flat rate on all your income.
  • Your "marginal rate" is the highest bracket you fall into; your "effective rate" is the average rate you pay on all your income, which is always lower.
  • You can find the 2024 tax brackets on the IRS website, and the IRS publishes new brackets each fall for the following year.
  • Deductions and credits reduce the income that is actually taxed, which lowers your effective rate even if your marginal rate stays the same.

How tax brackets work

Tax brackets are ranges of income, each with its own tax rate. When you earn income, it fills up the brackets from the bottom. The first portion of your income is taxed at 10%, the next portion at 12%, and so on, until all your income is assigned to a bracket. You do not jump to a higher rate all at once.

For example, if you are single in 2024 and earned $50,000, your income would be taxed like this: the first $11,600 is taxed at 10%, the next $47,150 (up to $58,750) is taxed at 12%, and the remaining $38,400 is taxed at 22%. You do not pay 22% on all $50,000. This is why your effective tax rate (the average rate on all your income) is always lower than your marginal tax rate (the highest bracket you reach).

Finding your marginal tax rate for 2024

Your marginal rate is the tax rate of the highest bracket your income reaches. To find it, you need to know your filing status and your taxable income (income after deductions). The IRS publishes tax brackets on its website at irs.gov under "Tax Brackets and Rates." Look for the table that matches your filing status.

The five filing statuses are: Single, Married Filing Jointly, Married Filing Separately, Head of Household, and may have access to Widow(er). Find the row that contains your taxable income, and that row shows your marginal rate. If your taxable income is $50,000 and you are single, you would look at the Single column and find the bracket that includes $50,000. In 2024, that is the 22% bracket.

Your taxable income is not the same as your gross income. Taxable income is what remains after you subtract the standard deduction (or itemized deductions if you itemize) and certain other deductions. If you are single in 2024, the standard deduction is $14,600, so if you earned $50,000, your taxable income would be $35,400.

The difference between marginal rate and effective rate

Many people confuse these two rates. Your marginal rate is the rate applied to your last dollar of income — the highest bracket you reach. Your effective rate is the average rate you pay on all your income combined. Your effective rate is always lower than your marginal rate because the lower brackets are taxed at lower rates.

Using the same example: if you are single, earned $50,000, and took the standard deduction, your taxable income is $35,400. Your marginal rate is 22% (the bracket that includes $35,400). But your effective rate is lower — roughly 12.5% — because much of your income was taxed at 10% and 12%. You can calculate your effective rate by dividing your total federal income tax by your taxable income.

Your marginal rate matters when you are deciding whether to earn more income or take a deduction. If you are in the 22% bracket, an extra $1,000 of income will cost you roughly $220 in federal tax. A $1,000 deduction will save you roughly $220. Your effective rate does not change your tax bill — it is just a way to see the big picture of what you paid overall.

How deductions and credits affect your rate

Deductions reduce your taxable income, which lowers the amount of income that is taxed. The standard deduction is the most common one — in 2024 it ranges from $14,600 for single filers to $29,200 for married couples filing jointly. If you itemize deductions instead (mortgage interest, state and local taxes, charitable donations), you can reduce your taxable income further if your itemized total exceeds the standard deduction.

Tax credits are different from deductions. A credit reduces your tax bill directly, dollar for dollar. The Earned Income Tax Credit (EITC) and the Child Tax Credit are the most common ones. A $1,000 deduction reduces your taxable income by $1,000, which saves you money based on your marginal rate. A $1,000 credit reduces your tax bill by $1,000 no matter what your rate is. Credits are more valuable than deductions of the same amount.

When tax brackets change

The IRS adjusts tax brackets every year to account for inflation. The brackets for the current year are published in October or November of the previous year. For example, the 2024 brackets were published in October 2023. If you are filing your 2024 taxes in 2025, you will use the 2024 brackets that were published in late 2023.

The brackets usually increase slightly each year, which means more of your income may fall into a higher bracket than it did the year before — even if your actual income did not increase much. This is called bracket creep. The IRS adjusts brackets to reduce this effect, but it still happens. You can find the current year's brackets and the previous year's brackets on irs.gov to compare.

Where to find the official tax brackets

The IRS publishes tax brackets on its official website at irs.gov. Search for "Tax Brackets and Rates" or look under the "Individuals" section. The page shows all five filing statuses and all seven tax rate brackets (10%, 12%, 22%, 24%, 32%, 35%, and 37%). The brackets are updated each fall for the following year.

You can also find tax brackets in IRS Publication 17, which is the official guide to federal income tax. Many tax software programs (TurboTax, H&R Block, TaxAct) display your marginal and effective rates when you enter your income and filing status. These software programs use the current year's brackets automatically, so you do not have to look them up yourself.

Frequently Asked Questions

Does my state income tax rate affect my federal rate?

No. Your federal income tax rate and your state income tax rate are completely separate. Some states have no income tax at all. Your federal rate depends only on your federal taxable income and filing status. State taxes are calculated separately and do not change your federal bracket.

If I earn more money, will I pay more in taxes on all my income?

No. Only the income in the higher bracket is taxed at the higher rate. If you earn an extra $1,000 and it pushes you into the next bracket, only that $1,000 (or the portion of it in the new bracket) is taxed at the new rate. Your existing income is still taxed at the same rates as before.

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

Your tax bracket is the range of income you fall into (for example, $11,601 to $47,150). Your tax rate is the percentage applied to that bracket (for example, 12%). You can have income in multiple brackets at once — the lower portions of your income are in lower brackets with lower rates.

Can I lower my federal tax rate by taking deductions?

Deductions lower your taxable income, which can move you into a lower bracket and reduce your effective rate. However, your marginal rate (the rate on your last dollar) stays the same unless your income drops enough to move you into a completely different bracket. Deductions always help, but they do not change your bracket unless you reduce your income significantly.

Where do I enter my tax rate when I file my taxes?

You do not enter your tax rate yourself. Tax software and tax forms calculate it automatically based on your income and filing status. When you file Form 1040, you report your income and deductions, and the IRS calculates your tax using the current year's brackets. The software you use will do this calculation for you.
