What is a federal tax bracket?
A federal tax bracket is a band of taxable income taxed at a single rate. The United States uses a progressive system with seven brackets — 10%, 12%, 22%, 24%, 32%, 35%, and 37% — so different slices of your income are taxed at different rates. This tax bracket lookup takes your taxable income and tells you instantly which bracket your top dollar lands in.
The rate on that top dollar is your marginal tax rate — and it is the single most misunderstood number in personal tax. Being "in the 22% bracket" does not mean you pay 22% of all your income. It means the last portion of your income is taxed at 22%, while the earlier portions are taxed at the lower rates beneath it.
How tax brackets work
Income is taxed in layers, not all at one rate. As your taxable income rises, it fills each bracket from the bottom up. Only the dollars that fall inside a given bracket are taxed at that bracket's rate — the dollars below it keep their lower rates.
- Find your taxable income. That is your gross income minus deductions (most filers take the standard deduction — $14,600 for a single filer in 2024).
- Fill the brackets from the bottom. The first dollars are taxed at 10%, the next band at 12%, and so on up the ladder.
- Your marginal rate is the bracket your last dollar reaches. That is the number this lookup returns.
A worked example using the tax bracket lookup
Maya is a single filer with $75,000 of taxable income for 2024. She enters 75,000 into the lookup — the tool's default — and wants to understand both her bracket and what she actually owes.
Step 1 — Find the marginal bracket
$75,000 is above the 22% threshold of $47,150 but below the 24% threshold of $100,525. So her top dollar lands in the 22% bracket — exactly what the lookup returns.
Step 2 — Tax each band at its own rate
- 10% × $11,600 (the first band) = $1,160.00
- 12% × $35,550 ($11,600 to $47,150) = $4,266.00
- 22% × $27,850 ($47,150 to $75,000) = $6,127.00
Step 3 — Add the bands and find the effective rate
Marginal vs effective tax rate
These are the two rates people mix up most. Your marginal rate is the rate on your next (or last) dollar of income — your bracket. Your effective rate is the average rate across all your income: total tax divided by taxable income. Because lower bands are taxed at lower rates, your effective rate is always below your marginal rate.
2024 federal income tax brackets
Below are the official IRS brackets for the 2024 tax year (returns filed in early 2025) — the data this lookup uses for the Single column. The thresholds are adjusted for inflation each year, so a future year's numbers will differ.
| Rate | Single | Married filing jointly | Head of household |
|---|---|---|---|
| 10% | $0 – $11,600 | $0 – $23,200 | $0 – $16,550 |
| 12% | $11,600 – $47,150 | $23,200 – $94,300 | $16,550 – $63,100 |
| 22% | $47,150 – $100,525 | $94,300 – $201,050 | $63,100 – $100,500 |
| 24% | $100,525 – $191,950 | $201,050 – $383,900 | $100,500 – $191,950 |
| 32% | $191,950 – $243,725 | $383,900 – $487,450 | $191,950 – $243,700 |
| 35% | $243,725 – $609,350 | $487,450 – $731,200 | $243,700 – $609,350 |
| 37% | $609,350+ | $731,200+ | $609,350+ |
Source: IRS Revenue Procedure 2023-34 (2024 inflation adjustments). This lookup applies the Single column. The 2024 standard deduction is $14,600 (single), $29,200 (married filing jointly), and $21,900 (head of household).
What counts as taxable income?
The brackets apply to taxable income, not your salary or your gross pay. Taxable income is what is left after subtracting deductions from your total income — and getting this number right is the difference between an accurate bracket and a misleading one.

Common tax bracket questions
What tax bracket am I in?
You are in the bracket your last dollar of taxable income reaches. For a single filer in 2024, $50,000 of taxable income is in the 22% bracket, $40,000 is in the 12% bracket, and $120,000 is in the 24% bracket. Enter your taxable income above to see your marginal bracket instantly.
Does being in the 22% bracket mean I pay 22% of my income?
No. The 22% applies only to the dollars inside the 22% band; the income below it is taxed at 10% and 12%. That is why your effective (average) rate is lower than your bracket — in the $75,000 example above, the bracket is 22% but the effective rate is about 15.4%.
Will a raise that bumps me into a higher bracket lower my take-home pay?
No. Only the income above the new bracket threshold is taxed at the higher rate; everything below it is unchanged. Earning more always leaves you with more after-tax money — there is no penalty for crossing a bracket line.
Is this the same for married or head-of-household filers?
The rates (10%–37%) are the same, but the income thresholds differ by filing status. This lookup uses the Single thresholds. Joint and head-of-household brackets are wider, so the same taxable income can land in a lower bracket — see the reference table above.
