Federal income tax rates are percentages the IRS uses to calculate how much tax you owe based on your income

The federal government taxes your income using a progressive tax system, which means the rate increases as your income increases. You do not pay one flat rate on all your income. Instead, your income is divided into brackets, and each bracket has its own rate. The lowest bracket starts at 10%, and the highest goes to 37%. The bracket you fall into depends on how much you earned that year and your filing status — whether you file as single, married filing jointly, head of household, or another category.

The key thing to understand is that moving into a higher bracket does not mean all your income gets taxed at that higher rate. Only the income that falls within each bracket gets taxed at that bracket's rate. For example, if you are single and earn $50,000, you do not pay 22% on the entire amount. Instead, you pay 10% on the first portion, 12% on the next portion, and 22% on only the portion that falls in the 22% bracket.

Key Takeaways

  • Federal tax brackets range from 10% to 37%, and the rate that applies to each portion of your income depends on which bracket that income falls into.
  • Tax brackets change each year for inflation, so the income ranges that trigger each rate are different in 2024 than they were in 2023.
  • Your filing status — single, married filing jointly, head of household, or other — determines which bracket thresholds explore to you.
  • The bracket you are in is not the same as your effective tax rate, which is the average rate you pay on all your income combined.

The seven federal tax brackets and how they work

There are seven federal income tax brackets for the 2024 tax year. Each bracket has a rate and an income range. The ranges differ based on your filing status. For a single filer in 2024, the brackets start at 10% for income up to $11,600, then 12% for income from $11,601 to $47,150, then 22% for income from $47,151 to $100,525, and so on up to 37% for income over $578,100. For married couples filing jointly, the ranges are wider — for example, the 22% bracket runs from $47,151 to $100,525 for singles but from $94,301 to $201,050 for married filing jointly.

The IRS publishes new bracket ranges every year because they adjust for inflation. This means the income thresholds that trigger each rate shift annually. A salary that put you in the 22% bracket in 2023 might fall into the 12% bracket in 2024 if the brackets widened enough. You can find the current year's brackets on the IRS website or on your tax software when you file.

What "marginal rate" and "effective rate" mean

Your marginal tax rate is the rate that applies to your last dollar of income — the highest bracket you reach. If you are single and earn $60,000, your marginal rate is 22% because that is the bracket your income falls into. However, your effective tax rate is the average rate you pay on all your income combined. It is always lower than your marginal rate because you paid 10% on the first chunk, 12% on the next chunk, and only 22% on the remainder. Your effective rate might be around 13% or 14% in this example.

This distinction matters when you think about earning more money. If you are in the 22% bracket and get a raise, you do not pay 22% on your entire new salary — only on the portion that exceeds your current income. That is why earning more money always results in more take-home pay, even though you move into a higher bracket.

How filing status affects your tax brackets

The IRS offers several filing statuses, and each one has different bracket thresholds. Single filers have the narrowest brackets. Married filing jointly filers have the widest brackets, which is one reason married couples often pay less total tax than two single people earning the same combined income. Head of household filers — usually unmarried people who pay more than half the household expenses for themselves and a dependent — fall between single and married filing jointly. Married filing separately is available but usually results in higher tax. may have access to widow or widower status is available for two years after a spouse's death and uses the same brackets as married filing jointly.

Your filing status is determined on December 31 of the tax year. If you get married on December 31, you can file as married for that entire year. If you get divorced on December 31, you file as single for that year. This status affects not only your tax brackets but also your standard deduction and your access to certain tax credits.

Standard deduction versus tax brackets

Before you calculate which bracket applies to you, you subtract your standard deduction from your income. The standard deduction is a set amount the IRS lets you deduct without itemizing expenses. For 2024, the standard deduction is $14,600 for single filers, $29,200 for married filing jointly, and $21,900 for head of household. These amounts also change each year for inflation.

This means if you are single and earn $50,000, you subtract $14,600 first, leaving $35,400 of taxable income. That $35,400 is what gets divided into brackets and taxed. You do not pay tax on the first $14,600. This is why people with lower incomes often owe no federal income tax at all — their income falls below the standard deduction.

Tax credits and deductions that reduce what you owe

Tax brackets tell you what rate applies to your income, but the amount you actually owe can be reduced by tax credits and deductions. Deductions lower your taxable income before the brackets are applied — like the standard deduction, or deductions for student loan interest or retirement contributions. Credits reduce the tax you owe after it is calculated. A $1,000 credit saves you $1,000 in tax, regardless of your bracket. Common credits include the Earned Income Tax Credit, the Child Tax Credit, and the American Opportunity Credit for education expenses.

This is why two people in the same tax bracket can owe very different amounts. One person might have no credits or deductions beyond the standard deduction, while another might have children, education expenses, or retirement savings that reduce their final tax bill significantly.

How to find out what your tax bracket is

To find your bracket, start with your filing status and your total income for the year. Subtract your standard deduction. Look at the remaining amount — your taxable income — and find which bracket range it falls into using the IRS's current-year bracket tables. You can find these tables on IRS.gov, or you can use tax software like TurboTax, H&R Block, or TaxAct, which will calculate your bracket automatically as you enter your information.

If you have a complicated situation — self-employment income, investment income, or multiple jobs — your tax software or a tax professional can help you understand which bracket applies and whether you owe estimated taxes throughout the year. Many employers use a W-4 form to withhold the right amount from each paycheck so you do not owe a large bill at tax time.

Frequently Asked Questions

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

No. Only the income that falls within each bracket gets taxed at that bracket's rate. If you earn $60,000 as a single filer, you pay 10% on the first $11,600, 12% on the next portion, and 22% on the remainder. Your overall effective rate is lower than your marginal rate.

What happens if I earn more money and move to a higher tax bracket?

You pay the higher rate only on the income that falls into the higher bracket, not on your entire salary. Earning more money always results in more take-home pay, even though a portion of it is taxed at a higher rate.

Are tax brackets the same every year?

No. The IRS adjusts bracket ranges annually for inflation. The income thresholds that trigger each rate change each year, which is why you should check the current year's brackets when you file.

How do tax credits differ from tax brackets?

Tax brackets determine the rate applied to your income. Tax credits reduce your final tax bill dollar-for-dollar after the rate is applied. A $1,000 credit saves you $1,000 regardless of your bracket.

What is the difference between my marginal rate and my effective rate?

Your marginal rate is the highest bracket you reach — the rate on your last dollar of income. Your effective rate is the average rate you pay on all your income combined. Your effective rate is always lower because you paid lower rates on earlier portions of your income.
