Federal income tax rates are set by Congress and change based on how much you earn

The federal government taxes income using a system called tax brackets. You do not pay one flat rate on all your income. Instead, your income is divided into chunks, and each chunk is taxed at a different rate. The rates range from 10% to 37%, depending on your income level and filing status. The higher your income, the higher the bracket you enter — but only the money in that bracket gets taxed at that rate.

For example, if you are single and earn $50,000 in 2024, you do not pay 22% on all of it. You pay 10% on the first portion, 12% on the next portion, and 22% only on the amount above a certain threshold. This is called progressive taxation. Your actual tax rate — the percentage you pay on your total income — is lower than your highest bracket rate.

Tax brackets change every year because Congress adjusts them for inflation. The IRS publishes new brackets each January. Your filing status matters: single filers, married couples filing jointly, married couples filing separately, and heads of household all have different bracket thresholds.

Key Takeaways

  • Federal tax brackets range from 10% to 37%, and you pay different rates on different portions of your income, not one rate on everything.
  • Your actual tax rate is lower than your highest bracket because only income above each threshold is taxed at that rate.
  • Tax brackets change yearly for inflation, so the income thresholds that trigger each rate shift every January.
  • Your filing status — single, married filing jointly, head of household, or married filing separately — determines which bracket thresholds apply to you.
  • Deductions and credits can lower your taxable income or your tax bill, which is separate from your bracket rate.

The seven federal tax brackets and how they work

There are seven federal tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Each bracket applies to a range of income. For single filers in 2024, the 10% bracket covers roughly the first $11,000 of income. The 12% bracket covers income above that up to roughly $44,725. The 22% bracket covers income above that up to roughly $95,375, and so on up to the 37% bracket, which applies to income above roughly $578,100.

The exact dollar amounts where each bracket begins and ends change every year. The IRS adjusts them based on inflation. Married couples filing jointly have higher thresholds for each bracket than single filers — meaning you can earn more before entering a higher bracket. Heads of household have thresholds between single and married filing jointly.

To find your bracket, you locate your filing status and your total income, then see which range it falls into. That tells you your marginal tax rate — the rate you pay on your last dollar of income. It does not tell you your effective tax rate, which is your total tax divided by your total income.

The difference between marginal rate and effective rate

Your marginal rate is the tax rate on your highest bracket — the rate you pay on your last dollar earned. Your effective rate is your total federal tax bill divided by your total income. These are almost never the same, and understanding the difference matters.

Say you are single and earn $60,000. Your marginal rate might be 22% because $60,000 falls in the 22% bracket. But your effective rate is lower — perhaps 10% or 11% — because you paid 10% on the first chunk, 12% on the next chunk, and 22% only on the portion above the 22% bracket threshold. When someone asks "what tax rate do you pay," they usually mean your effective rate, not your marginal rate.

This is why earning more money does not mean you take home less. Moving into a higher bracket only affects the income in that bracket, not all your income. The money you earn in a lower bracket is always taxed at that lower rate.

How deductions and credits affect your tax bill

Your tax bracket is based on your income, but your actual tax bill depends on deductions and credits. A deduction reduces the income that gets taxed — your taxable income. A credit reduces your tax bill dollar for dollar.

The most common deduction is the standard deduction. For 2024, the standard deduction is roughly $14,600 for single filers and $29,200 for married couples filing jointly. You subtract this amount from your total income before calculating tax. So if you earn $50,000 and take the standard deduction, your taxable income is $35,400, not $50,000. You pay tax only on $35,400.

Some people itemize deductions instead — listing specific expenses like mortgage interest or charitable donations. Others claim tax credits, which directly reduce the tax owed. The Earned Income Tax Credit (EITC) and the Child Tax Credit are common examples. These credits can lower your tax bill below what your bracket alone would suggest, or even result in a refund.

Why tax brackets changed in 2017 and when they change again

In 2017, Congress passed the Tax Cuts and Jobs Act, which changed tax brackets, standard deductions, and many other rules. The law lowered rates for most brackets and widened the income ranges for each bracket. These changes were set to expire at the end of 2025 unless Congress acts to extend them.

If no action is taken, tax brackets will revert to their pre-2017 levels starting in 2026. This means rates would go up for most filers, and the income ranges for each bracket would narrow. Congress may vote to extend the current brackets, modify them, or let them expire. The outcome is uncertain and depends on political decisions made in 2025.

Regardless of what Congress does, the IRS adjusts bracket thresholds every year for inflation. Even if the rates themselves stay the same, the income levels that trigger each bracket shift upward annually. You can find the current year's brackets on the IRS website or on your tax software.

How to find your tax bracket for the current year

The IRS publishes tax bracket tables every January on its official website (irs.gov). Search for "tax brackets" and the current year. You will find tables organized by filing status: single, married filing jointly, married filing separately, and head of household.

Locate your filing status and your total income. Find the row where your income falls. That row shows your marginal tax rate — your bracket. Remember that this is not your effective rate; it is only the rate on your highest income.

Your tax software — whether you use TurboTax, H&R Block, or the IRS Free File program — calculates your effective rate and your total tax automatically. You do not need to do the math yourself. But knowing your bracket helps you understand how your income is taxed and why earning more does not always mean paying proportionally more in tax.

Frequently Asked Questions

Does everyone in the same tax bracket pay the same amount of tax?

No. Two people in the same bracket can owe very different amounts because deductions and credits vary. One person might claim the standard deduction; another might itemize. One might have children and claim the Child Tax Credit; another might not. Your bracket is just the starting point.

If I earn one more dollar and move to a higher bracket, do I lose money?

No. Only the income in the higher bracket is taxed at the higher rate. The money you earned in the lower bracket stays taxed at the lower rate. Earning more always means taking home more, even if you move to a higher bracket.

Why do tax brackets change every year?

The IRS adjusts brackets annually for inflation so that wage increases due to inflation do not push you into a higher bracket. Without this adjustment, you would pay more tax even if your purchasing power stayed the same. This is called "bracket creep."

What is the difference between federal tax and state tax?

Federal tax is collected by the IRS and goes to the national government. State tax is collected by your state and goes to your state government. Some states have no income tax; others have rates ranging from 1% to over 13%. Your total tax bill includes both federal and state, plus local taxes in some areas.

Can I lower my tax bracket by taking deductions?

Deductions lower your taxable income, which can move you into a lower bracket. But your bracket is based on your actual income, not your taxable income. Deductions reduce the income that gets taxed, but they do not change which bracket your income falls into — they just reduce how much of your income is subject to tax.
