The federal income tax rate depends on how much you earn and your filing status
The United States uses a progressive tax system, which means the rate you pay increases as your income increases. You do not pay one flat rate on all your income. Instead, your income is divided into brackets, and you pay a different rate on each bracket. For 2024, the federal rates range from 10 percent on the lowest bracket to 37 percent on the highest.
The brackets themselves change each year based on inflation. A single person earning $47,150 in 2024 pays a different top rate than someone earning the same amount in 2023, because the bracket thresholds shifted. This means you need to check the current year's brackets when you file, not rely on last year's numbers.
Your filing status — single, married filing jointly, married filing separately, or head of household — determines which bracket thresholds explore to you. A married couple filing jointly reaches higher income levels before hitting the top brackets than a single filer does, which is why married couples often pay less total tax on the same combined income.
Key Takeaways
- Federal tax brackets range from 10 percent to 37 percent, and you pay the lowest rate only on income within the lowest bracket, not on your entire income.
- The income thresholds for each bracket change every year, so the same salary can put you in a different bracket from one year to the next.
- Your filing status — single, married filing jointly, or head of household — determines which bracket thresholds explore to you.
- The rate printed on a bracket is your marginal rate, not your effective rate; your effective rate is always lower because you pay lower rates on the income below.
- Self-employed people pay federal income tax plus an additional 15.3 percent self-employment tax on net earnings.
How tax brackets actually work with an example
Suppose you are single and earned $60,000 in 2024. You do not pay 22 percent (the bracket rate for that income level) on all $60,000. Instead, you pay 10 percent on the first $11,600, then 12 percent on the income from $11,601 to $47,150, then 22 percent only on the income from $47,151 to $60,000.
This layering is why your effective tax rate — the percentage of your total income that goes to federal tax — is always lower than your marginal rate (the rate on your last dollar earned). In this example, your effective rate would be roughly 13 percent, not 22 percent, even though 22 percent is the bracket you fall into.
Understanding this distinction matters because it affects decisions about deductions, retirement contributions, and side income. A raise that pushes you into a higher bracket does not mean all your income is taxed at the new rate — only the income above the threshold.
The 2024 federal tax brackets for each filing status
| Tax Rate | Single Filers | Married Filing Jointly | Head of Household |
|---|---|---|---|
| 10% | $0 to $11,600 | $0 to $23,200 | $0 to $17,400 |
| 12% | $11,601 to $47,150 | $23,201 to $94,300 | $17,401 to $66,550 |
| 22% | $47,151 to $100,525 | $94,301 to $201,050 | $66,551 to $100,525 |
| 24% | $100,526 to $191,950 | $201,051 to $383,900 | $100,526 to $191,950 |
| 32% | $191,951 to $243,725 | $383,901 to $487,450 | $191,951 to $243,700 |
| 35% | $243,726 to $609,350 | $487,451 to $731,200 | $243,701 to $609,350 |
| 37% | $609,351+ | $731,201+ | $609,351+ |
These thresholds are set by the IRS each year and published before tax season begins. The brackets for 2025 will be slightly higher than 2024 to account for inflation. You can find the current year's brackets on the IRS website or on the tax forms and instructions you receive.
Standard deduction and how it reduces your taxable income
Before the brackets explore, you subtract the standard deduction from your gross income. This deduction is a set amount that depends on your age and filing status. For 2024, a single person under 65 gets a $14,600 deduction, and a married couple filing jointly gets $29,200.
This means if you earned $60,000 as a single filer, your taxable income is actually $45,400 ($60,000 minus $14,600). The brackets then explore to that $45,400, not to your full earnings. The standard deduction is one of the largest tax breaks most people receive, and it is why many people with modest incomes owe little or no federal tax.
If you have significant deductible expenses — mortgage interest, charitable donations, medical costs — you may benefit from itemizing deductions instead of taking the standard deduction. Most people use the standard deduction because it is simpler and often larger than their itemized deductions would be.
Self-employment tax on top of income tax
If you are self-employed or own a business, you pay federal income tax on your net earnings using the same brackets as everyone else. But you also pay self-employment tax, which is 15.3 percent on net earnings above $400. This covers Social Security and Medicare taxes that an employer would normally withhold from a paycheck.
Self-employment tax is calculated separately from income tax and is owed in addition to it. A self-employed person earning $50,000 in net profit pays both the income tax based on the brackets and the 15.3 percent self-employment tax. You can deduct half of your self-employment tax when calculating your adjusted gross income, which provides some relief, but the full amount is still owed.
Quarterly estimated tax payments are required if you expect to owe $1,000 or more in federal tax for the year. These payments are due on April 15, June 15, September 15, and January 15 of the following year.
Tax credits and withholding affect what you actually pay
Your federal tax bracket tells you what rate applies to your income, but the amount you actually owe depends on tax credits and how much was withheld from your paychecks during the year. A tax credit directly reduces the tax you owe, dollar for dollar, which is different from a deduction that reduces your taxable income.
Common credits include the Earned Income Tax Credit (EITC) for lower-income workers, the Child Tax Credit for parents, and the American Opportunity Credit for education expenses. These credits can reduce your tax bill to zero or even result in a refund if the credit exceeds what you owe.
If you are an employee, your employer withholds federal tax from each paycheck based on the W-4 form you filled out. If too much is withheld, you get a refund when you file. If too little is withheld, you owe when you file. The brackets determine the rate, but withholding and credits determine the final amount due.
Frequently Asked Questions
Does everyone pay the 37 percent rate if they earn enough?
No. Only the income above the threshold for the 37 percent bracket is taxed at that rate. Someone earning $750,000 pays 37 percent only on the amount above $609,350. The income below that threshold is taxed at the lower rates for each bracket. This is why high earners still have an effective tax rate well below 37 percent.
What is the difference between federal tax and state tax?
Federal tax goes to the U.S. government and uses the brackets described here. State income tax is separate and varies by state — some states have no income tax, while others have rates ranging from about 1 percent to over 13 percent. You owe both if your state has an income tax. They are calculated independently on your federal and state tax returns.
Do the tax brackets change every year?
Yes. The IRS adjusts the income thresholds for each bracket annually to account for inflation. The rates themselves (10, 12, 22, etc.) stay the same, but the dollar amounts that trigger each rate shift. This adjustment is called indexing, and it means your income can stay flat while you move into a higher bracket, or you can get a raise without moving to a higher bracket.
Can I reduce my federal tax by contributing to a retirement account?
Yes. Contributions to a traditional 401(k) or traditional IRA reduce your taxable income, which lowers the amount subject to the brackets. A Roth 401(k) or Roth IRA does not reduce your current taxable income, but the withdrawals in retirement are tax-free. The choice depends on whether you expect to be in a higher or lower tax bracket in retirement.
What happens if I do not have enough withheld during the year?
You will owe the remaining tax when you file your return. If you owe more than $1,000, you may also owe a penalty for underpayment of estimated tax. You can adjust your W-4 with your employer to increase withholding, or if you are self-employed, you can make quarterly estimated payments to avoid a large bill at filing time.
