Federal tax brackets are income ranges where you pay a set tax rate on money within that range
The federal government divides income into brackets, and you pay a different percentage on the money that falls into each one. The brackets change every year because they adjust for inflation. For 2024, there are seven brackets ranging from 10% to 37%. The key thing to understand: you do not pay one rate on all your income. Instead, you pay 10% on the first chunk, then 12% on the next chunk, and so on, depending on how much you earn and your filing status.
Your filing status — single, married filing jointly, married filing separately, or head of household — determines which bracket you fall into. Two people earning the same amount might owe different taxes because they file differently. The IRS publishes new bracket ranges each January, so the dollar amounts shift annually even if the rates stay the same.
Key Takeaways
- Tax brackets are income ranges, not a single rate applied to all your earnings; you pay different percentages on different portions of your income.
- The seven federal tax rates for 2024 are 10%, 12%, 22%, 24%, 32%, 35%, and 37%, and the income ranges that trigger each rate depend on whether you file as single, married jointly, or head of household.
- Earning more money can move you into a higher bracket, but only the income above the threshold is taxed at the new rate — your existing income is not retroactively taxed higher.
- Bracket ranges adjust annually for inflation, so the dollar amounts change every year even when the tax rates remain the same.
How the bracket system actually works with an example
Say you are single and earned $50,000 in 2024. You do not pay 22% on all $50,000. Instead, you pay 10% on the first $11,600, then 12% on the income between $11,601 and $47,150, then 22% on the remaining $2,850. Your total tax is the sum of those three amounts, not 22% of $50,000. This is called progressive taxation — the rate increases as your income rises, but each bracket applies only to the income within that range.
If you earn $1,000 more and move into the next bracket, that extra $1,000 is taxed at the higher rate. The income you already earned is not recalculated at the new rate. This is why people sometimes worry about a raise pushing them into a higher bracket and leaving them worse off — it does not work that way. A higher bracket always means more take-home pay, even if the percentage you owe on new income is higher.
The 2024 federal tax brackets by filing status
| Tax Rate | Single | Married Filing Jointly | Head of Household |
|---|---|---|---|
| 10% | $0–$11,600 | $0–$23,200 | $0–$17,400 |
| 12% | $11,601–$47,150 | $23,201–$94,300 | $17,401–$65,900 |
| 22% | $47,151–$100,525 | $94,301–$201,050 | $65,901–$100,500 |
| 24% | $100,526–$191,950 | $201,051–$383,900 | $100,501–$191,950 |
| 32% | $191,951–$243,725 | $383,901–$487,450 | $191,951–$243,700 |
| 35% | $243,726–$609,350 | $487,451–$731,200 | $243,701–$609,350 |
| 37% | $609,351+ | $731,201+ | $609,351+ |
These ranges apply to ordinary income — wages, salary, and self-employment income. Investment income, capital gains, and certain other types of income may be taxed differently. Married couples filing jointly have wider brackets than single filers, which is why marriage can affect your overall tax burden. Head of household status (usually for unmarried parents supporting dependents) falls between single and married filing jointly.
The bracket ranges shown here are for the 2024 tax year. When you file your 2024 taxes in 2025, you will use these numbers. The IRS will announce 2025 brackets in late October or early November 2024, and those will apply to income earned in 2025.
Why brackets change every year
The IRS adjusts bracket ranges annually to account for inflation. If brackets never changed, inflation would push more of your income into higher tax rates even if your actual purchasing power stayed the same. This is called bracket creep. By adjusting the ranges upward each year, the government keeps the tax system roughly aligned with the cost of living.
The adjustment is usually small — often a few hundred dollars per bracket — but it compounds over time. The IRS announces the new brackets in late October or early November for the following tax year. If you are self-employed or manage your own withholding, you should check the new brackets when they come out to see if you need to adjust how much tax you set aside.
How your employer uses brackets to withhold taxes
Your employer does not calculate your taxes using the bracket system directly. Instead, they use a W-4 form and IRS withholding tables to estimate how much federal income tax to take from each paycheck. The withholding tables are built on the bracket system, but they spread the annual tax across your paychecks so you do not owe a large lump sum on April 15.
If your withholding is too high, you get a refund. If it is too low, you owe money when you file. You can adjust your withholding by submitting a new W-4 to your employer — for example, if you got a raise, had a second job, or got married. The more accurately your W-4 reflects your situation, the closer your withholding will be to what you actually owe.
Effective tax rate versus marginal tax rate
Your marginal tax rate is the rate you pay on your last dollar of income — the highest bracket you reach. Your effective tax rate is the average rate you pay on all your income. For most people, the effective rate is much lower than the marginal rate because most of their income is taxed at lower brackets.
If you are single and earn $50,000, your marginal rate is 22%, but your effective rate is roughly 8%. This matters when you are thinking about whether a raise is worth it or whether a deduction saves you money. A deduction saves you money at your marginal rate, not your effective rate. A $1,000 deduction saves you $220 in taxes if your marginal rate is 22%, not $80.
Frequently Asked Questions
Does earning more money ever put me in a worse financial position because of taxes?
No. Moving into a higher tax bracket means you pay a higher rate only on the income above the threshold. Your existing income is taxed at the same rates as before. Earning an extra $1,000 might mean paying $220 in taxes on that $1,000 if your marginal rate is 22%, but you still take home $780 more than you did before.
What is the difference between federal tax brackets and state tax brackets?
Federal brackets apply to income tax owed to the U.S. government. State brackets apply to income tax owed to your state, and they are separate. Some states have no income tax, while others have their own bracket systems. You may owe federal tax, state tax, both, or neither depending on where you live and work.
Can I reduce my taxable income to stay in a lower bracket?
Yes, through deductions and contributions to certain accounts. Contributing to a traditional 401(k) or IRA reduces your taxable income, as do itemized deductions or the standard deduction. However, the goal is usually to reduce your total tax owed, not to stay in a lower bracket — reducing taxable income saves you money at your marginal rate regardless of which bracket you end up in.
Do tax brackets apply to self-employed income?
Yes, but self-employed people also owe self-employment tax (Social Security and Medicare), which is separate from income tax. Self-employment tax is roughly 15.3% on 92.35% of your net self-employment income. You pay income tax on top of that using the same brackets as employees, though you can deduct half of your self-employment tax.
