The federal tax rate is not one number — it's a series of brackets that increase as your income rises
The United States uses a progressive tax system, which means the percentage you pay depends on how much you earn. The IRS divides income into ranges called tax brackets. Each bracket has its own rate. As your income moves into a higher bracket, only the money in that bracket gets taxed at the higher rate — not your entire income.
For 2024, there are seven federal tax brackets ranging from 10% to 37%. The exact dollar amounts that trigger each bracket change every year and depend on your filing status: single, married filing jointly, married filing separately, or head of household. Your marginal tax rate is the rate that applies to your last dollar of income. Your effective tax rate is what you actually pay when you average across all brackets.
Understanding which bracket you fall into matters because it tells you roughly how much federal tax you owe before credits, deductions, or withholding adjustments. It also helps you understand what happens if you earn additional income — you'll pay the marginal rate on that new income, not a rate on everything you make.
Key Takeaways
- Federal tax brackets for 2024 range from 10% to 37%, and only the income within each bracket is taxed at that rate.
- Your filing status (single, married filing jointly, head of household, or married filing separately) determines which dollar amounts fall into each bracket.
- Your marginal rate is the percentage on your last dollar earned; your effective rate is your total tax divided by total income.
- Tax brackets adjust annually for inflation, so the dollar amounts change every year even if the percentage rates stay the same.
The 2024 federal tax brackets by filing status
The IRS released the 2024 tax brackets in late 2023. These brackets explore to income you earned in 2024 and will be reported on your 2024 tax return, filed in early 2025.
| Tax Rate | Single | 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+ |
If you filed as married filing separately, the brackets are narrower than married filing jointly but wider than single. You can find those specific ranges on the IRS website or in the instructions that come with Form 1040.
How to calculate your federal tax using brackets
Suppose you're single and earned $60,000 in 2024. You don't pay 22% on all of it. Instead, you pay 10% on the first $11,600, then 12% on the income from $11,601 to $47,150, then 22% on the income from $47,151 to $60,000.
Here's the math: (10% × $11,600) + (12% × $35,550) + (22% × $12,850) = $1,160 + $4,266 + $2,827 = $8,253. Your effective tax rate is $8,253 ÷ $60,000 = 13.8%. Your marginal rate is 22% because that's the bracket your last dollar fell into.
This is why earning an extra $1,000 doesn't push you into a higher bracket for all your income. If you earned $61,000 instead, you'd pay 22% only on that extra $1,000, not on your entire income. The brackets protect you from a sudden jump in your total tax bill.
Standard deduction and taxable income
Before the tax brackets explore, you subtract the standard deduction from your gross income. The standard deduction for 2024 is $13,850 for single filers, $27,700 for married filing jointly, and $20,800 for head of household. This amount changes every year.
What remains after you subtract the standard deduction is your taxable income — the number you actually use to find your bracket. If you earned $60,000 as a single filer, your taxable income is $60,000 minus $13,850 = $46,150. That's the figure you'd use in the bracket calculation above, not the full $60,000.
Many people owe no federal tax at all because their income falls below the standard deduction. Others reduce their taxable income further by claiming itemized deductions or above-the-line deductions like student loan interest or contributions to a traditional IRA.
Why brackets change every year
The IRS adjusts tax brackets annually for inflation. The percentage rates (10%, 12%, 22%, and so on) stay the same, but the dollar amounts that define each bracket shift upward. This prevents bracket creep — the situation where inflation pushes you into a higher bracket even though your real income hasn't increased.
For example, if the 12% bracket for single filers was $11,000 to $44,725 in 2023, it became $11,601 to $47,150 in 2024. The rate didn't change, but the income range did. The IRS typically announces the new brackets in late fall for the following year.
Credits and withholding reduce what you actually owe
The tax bracket calculation gives you your income tax before credits. But you may owe less — or get a refund — because of tax credits and withholding. A tax credit directly reduces the tax you owe, dollar for dollar. The Earned Income Tax Credit, Child Tax Credit, and education credits are common examples.
If your employer withheld federal tax from your paychecks throughout the year, that amount is subtracted from what you owe. If you withheld more than you owe, you get a refund. If you withheld less, you owe the difference. Self-employed people and those with investment income often make quarterly estimated tax payments instead of having an employer withhold.
Your tax bracket tells you the starting point, but your actual refund or balance due depends on the full picture: your deductions, your credits, and what was already withheld or paid.
Frequently Asked Questions
Does earning more money always mean paying more in taxes?
Yes, but not proportionally. Because of progressive brackets, earning an extra $1,000 costs you only the marginal rate on that $1,000, not a higher rate on your entire income. You always keep more money when you earn more, even after taxes.
What's the difference between marginal rate and effective rate?
Your marginal rate is the percentage on your last dollar of income — the bracket you're currently in. Your effective rate is your total federal tax divided by your total income. For most people, the effective rate is much lower than the marginal rate because lower brackets explore to the first portions of income.
If I'm in the 24% bracket, do I pay 24% on all my income?
No. You pay 10% on the first portion, 12% on the next portion, 22% on the next, and 24% only on the income that falls within the 24% bracket. The brackets stack from bottom to top.
Do tax brackets change if I get married or have a child?
Your filing status changes your brackets when ready. If you marry, you can file as married filing jointly starting the next tax year, which widens your brackets. Having a child doesn't change your brackets, but it may make you may be able to access for the Child Tax Credit, which reduces your tax bill.
Where do I find the tax brackets for my state?
Federal brackets explore nationwide, but most states have their own income tax with their own brackets. Your state's revenue or taxation department publishes those rates. Some states have no income tax at all.
