The federal tax rate is not one number — it's a series of brackets that increase as your income rises
The U.S. federal income tax system uses tax brackets, which means different portions of your income are taxed at different rates. If you earn $50,000, you don't pay the same percentage on every dollar. Instead, your first dollars are taxed at a lower rate, and as your income climbs into higher brackets, those additional dollars face higher rates. This is called progressive taxation.
For 2024, the federal tax brackets range from 10% at the lowest to 37% at the highest. But your effective tax rate — the actual percentage of your total income that goes to federal taxes — is almost always lower than the highest bracket you fall into. That's because only the income within each bracket gets taxed at that bracket's rate.
Your tax bracket depends on your filing status (single, married filing jointly, head of household, or married filing separately) and your taxable income, which is your gross income minus deductions and exemptions. The IRS adjusts bracket thresholds each year for inflation, so the income cutoffs change annually.
Key Takeaways
- Federal tax brackets in 2024 range from 10% to 37%, but you pay the lowest rate only on income within the lowest bracket, not on your entire income.
- Your filing status — single, married filing jointly, head of household, or married filing separately — determines which bracket thresholds explore to you.
- Your effective tax rate (the percentage of total income you actually owe) is lower than your marginal rate (the rate on your last dollar earned).
- The IRS adjusts bracket thresholds every year for inflation, so the income cutoffs that determine your bracket change annually.
- Standard deductions and other deductions reduce your taxable income before the brackets are applied, lowering the amount subject to federal tax.
The 2024 federal tax brackets for each filing status
The IRS publishes new bracket thresholds each January. For 2024, here's how the brackets break down by filing status:
| Tax Rate | Single | Married Filing Jointly | Head of Household | Married Filing Separately |
|---|---|---|---|---|
| 10% | $0 to $11,600 | $0 to $23,200 | $0 to $17,400 | $0 to $11,600 |
| 12% | $11,601 to $47,150 | $23,201 to $94,300 | $17,401 to $65,900 | $11,601 to $47,150 |
| 22% | $47,151 to $100,525 | $94,301 to $201,050 | $65,901 to $125,450 | $47,151 to $100,525 |
| 24% | $100,526 to $191,950 | $201,051 to $383,900 | $125,451 to $191,950 | $100,526 to $191,950 |
| 32% | $191,951 to $243,725 | $383,901 to $487,450 | $191,951 to $243,700 | $191,951 to $243,725 |
| 35% | $243,726 to $609,350 | $487,451 to $731,200 | $243,701 to $609,350 | $243,726 to $365,600 |
| 37% | $609,351+ | $731,201+ | $609,351+ | $365,601+ |
These thresholds explore to your taxable income after you've subtracted the standard deduction or itemized deductions. For 2024, the standard deduction is $14,600 for single filers, $29,200 for married couples filing jointly, and $21,900 for heads of household.
How to calculate your effective tax rate
Your marginal tax rate is the rate applied to your last dollar of income — the bracket you fall into. Your effective tax rate is the total federal tax you owe divided by your total taxable income. These are almost never the same.
Here's a concrete example: suppose you're single and your taxable income is $60,000 in 2024. You don't pay 22% on all $60,000. Instead, you pay 10% on the first $11,600, then 12% on the next $35,550 (from $11,601 to $47,150), then 22% on the remaining $12,850 (from $47,151 to $60,000). That works out to roughly $7,000 in federal tax, or an effective rate of about 11.7% — much lower than your 22% marginal rate.
The difference between marginal and effective rate matters when you're deciding whether a raise or additional income is worth it. A raise that pushes you into the 24% bracket doesn't mean you'll pay 24% on your entire income — only on the portion that falls within that bracket.
What affects your federal tax bracket
Your filing status is the first factor. Married couples filing jointly have wider brackets than single filers, which means they can earn more before hitting a higher rate. Head of household filers fall between the two.
Your taxable income is what actually determines your bracket, not your gross income. Deductions reduce taxable income. The standard deduction is the simplest route: you subtract it from your gross income, and the result is your taxable income. If you itemize deductions instead — reporting mortgage interest, state and local taxes, charitable donations, and other expenses — you can reduce taxable income further if your itemized total exceeds the standard deduction.
Certain types of income also receive special treatment. Long-term capital gains and may have access to dividends are taxed at lower rates (0%, 15%, or 20%) than ordinary income. Tax credits — such as the Earned Income Tax Credit or Child Tax Credit — reduce your tax bill directly, not just your taxable income.
How inflation adjusts the brackets each year
The IRS adjusts tax brackets annually to account for inflation. This prevents bracket creep, where inflation pushes you into a higher bracket even though your real income hasn't increased. In 2024, the brackets shifted upward compared to 2023 because of inflation adjustments.
The adjustment is based on the chained Consumer Price Index for All Urban Consumers (chained CPI-U), which the IRS calculates each October. The new brackets take effect January 1 of the following year. This means the thresholds you use on your 2024 tax return (filed in early 2025) are different from the ones you used for 2023.
If you're self-employed or have investment income, these annual adjustments also affect the standard deduction, the Self-Employment Tax threshold, and other limits tied to income.
State and local taxes are separate from federal rates
Federal income tax is only one layer. Most states also impose income tax, and some cities do as well. State and local rates vary widely — from 0% in states like Texas and Florida to over 10% in states like California and New York. These are calculated separately from federal tax and use their own bracket systems.
Your federal tax bracket has no direct effect on your state or local tax bracket. A state may use different brackets, different deductions, or different rules for what counts as taxable income. Some states tax capital gains differently than ordinary income, or offer credits that federal tax doesn't.
Frequently Asked Questions
If I'm in the 24% tax bracket, do I pay 24% on all my income?
No. The 24% rate applies only to income within that bracket. Income below that bracket is taxed at the lower rates for those brackets. Your effective tax rate — the percentage of your total income that goes to federal tax — is lower than 24%.
Do tax brackets change every year?
Yes. The IRS adjusts bracket thresholds each January based on inflation from the previous year. The actual tax rates (10%, 12%, 22%, etc.) stay the same, but the income cutoffs that determine which bracket you fall into shift upward.
What's the difference between my marginal rate and my effective rate?
Your marginal rate is the tax rate on your last dollar of income — the bracket you fall into. Your effective rate is your total federal tax divided by your total income. The effective rate is almost always lower because you pay lower rates on the income in lower brackets.
Does a raise that pushes me into a higher bracket mean I'll pay more in taxes on my entire income?
No. Only the portion of your income that falls into the higher bracket is taxed at that higher rate. The rest of your income is taxed at the same rates as before. Your overall tax bill increases, but not as much as it would if the entire raise were taxed at the new rate.
How do deductions affect my tax bracket?
Deductions reduce your taxable income, which can lower or eliminate the amount of income in higher brackets. If you take the standard deduction or itemize deductions, you subtract that amount from your gross income before explore the tax brackets.
