Federal income tax brackets are ranges of income that determine what percentage of tax you owe
The federal government uses a system called tax brackets to calculate how much income tax you pay. Each bracket is a range of income paired with a tax rate — the percentage of that income you owe in federal tax. The key thing to understand: you do not pay one rate on all your income. Instead, you pay different rates on different portions of your income, moving from the lowest bracket to the highest as your total income increases.
For example, if you are single and earned $50,000 in 2024, you would not pay the same rate on all $50,000. Instead, you would pay the lowest rate on the first chunk of income, a higher rate on the next chunk, and so on, until you reach $50,000. This is called the progressive tax system.
Tax brackets change every year because they are adjusted for inflation. The IRS publishes new brackets each January. Your filing status — single, married filing jointly, married filing separately, or head of household — determines which bracket table you use.
Key Takeaways
- Tax brackets are income ranges, and you pay different tax rates on different portions of your income, not one rate on everything you earn.
- The 2024 federal tax brackets for single filers range from 10% on the first $11,600 of income to 37% on income over $578,100, with six brackets in between.
- Your filing status (single, married filing jointly, head of household, or married filing separately) determines which bracket table applies to you.
- Tax brackets are adjusted each year for inflation, so the income ranges and rates change annually.
- Your marginal tax rate — the rate on your last dollar of income — is not the same as your effective tax rate, which is your total tax divided by your total income.
2024 Federal Tax Brackets for Single Filers
If you file as single, these are the 2024 federal income tax brackets:
| Tax Rate | Income Range |
|---|---|
| 10% | $0 to $11,600 |
| 12% | $11,601 to $47,150 |
| 22% | $47,151 to $100,525 |
| 24% | $100,526 to $191,950 |
| 32% | $191,951 to $243,725 |
| 35% | $243,726 to $609,350 |
| 37% | $609,351 and above |
These ranges apply to your taxable income, which is your total income minus deductions. Most people use the standard deduction, which for single filers in 2024 is $14,600. This means if you earned $50,000, your taxable income would be $35,400 ($50,000 minus $14,600).
2024 Federal Tax Brackets for Married Filing Jointly
If you file as married filing jointly, the income ranges are wider because two incomes are combined:
| Tax Rate | Income Range |
|---|---|
| 10% | $0 to $23,200 |
| 12% | $23,201 to $94,300 |
| 22% | $94,301 to $201,050 |
| 24% | $201,051 to $383,900 |
| 32% | $383,901 to $487,450 |
| 35% | $487,451 to $731,200 |
| 37% | $731,201 and above |
The standard deduction for married filing jointly in 2024 is $29,200. Notice that the income ranges for married filers are not exactly double those for single filers — this is intentional, and it is one reason why filing status matters for your tax bill.
How to Calculate Your Tax Using Brackets
To see how brackets work in practice, here is a step-by-step example. Suppose you are single, earned $60,000 in wages, and took the standard deduction of $14,600. Your taxable income is $45,400.
Using the single filer brackets above, you would calculate tax this way: 10% on the first $11,600 ($1,160), plus 12% on the next $35,550 ($4,266), for a total federal income tax of $5,426. Your marginal rate is 12% because that is the rate on your last dollar of income. But your effective rate is 12% of $45,400, or about 11.9% — lower than your marginal rate.
This is why people sometimes say "I am in the 22% bracket" when they mean their marginal rate is 22%, but their actual tax bill is lower. The brackets do not mean you pay that rate on all your income.
Other Filing Statuses: Head of Household and Married Filing Separately
Head of household filers — usually unmarried people who pay more than half the household expenses and have a dependent — get bracket ranges between single and married filing jointly. For 2024, the first bracket (10%) covers income up to $16,550.
Married filing separately filers use the same bracket ranges as single filers, which usually results in a higher total tax bill than filing jointly. This status is rarely advantageous unless spouses have very different incomes or are in the middle of a separation.
You can find the complete 2024 bracket tables for all filing statuses on the IRS website or in the tax instructions that come with your return form.
Why Brackets Change Every Year
The IRS adjusts tax brackets each year to account for inflation. If brackets stayed the same while wages rose, more of your income would fall into higher brackets even if your purchasing power had not changed. This adjustment is called bracket creep prevention.
Because brackets change annually, the income ranges you see in 2024 will be different in 2025. The IRS usually announces the new brackets in late October or early November of the prior year. If you are planning your finances or estimating your tax bill, check the current year's brackets rather than relying on old numbers.
Frequently Asked Questions
Does being in a higher tax bracket mean I pay that rate on all my income?
No. You only pay the higher rate on the portion of your income that falls into that bracket. The rest of your income is taxed at the lower rates of the brackets below it. This is why your effective tax rate is always lower than your marginal rate.
What is the difference between marginal rate and effective rate?
Your marginal rate is the tax rate on your last dollar of income — the highest bracket your income reaches. Your effective rate is your total tax bill divided by your total income. For most people, the effective rate is several percentage points lower than the marginal rate.
Do state and local taxes use the same brackets as federal tax?
No. Each state sets its own tax brackets and rates, and some states have no income tax at all. Local taxes vary by city and county. You will owe federal tax, state tax (if your state has one), and possibly local tax, each calculated separately using different brackets.
If I earn more money, will I end up paying more in total tax?
Yes, but not at the higher rate on all your income. If you move into a higher bracket, you pay the new rate only on the income above the previous bracket's limit. The income below that threshold is still taxed at the lower rates. This is why earning more money always results in more take-home pay, even though your tax rate goes up.
When do I use my filing status to determine my brackets?
You choose your filing status when you file your tax return each year. Your status on December 31 of the tax year determines which brackets you use. If you got married in December, you can file as married for that entire year. If you got divorced, you file as single for that year.
