US Tax Bracket Calculator (2025)
Find your marginal bracket, your effective rate, and exactly how much of your income falls in each bracket — federal or any state.
Brackets apply to taxable income (gross minus your standard deduction) — shown below.
US Tax Bracket Calculator
“What tax bracket am I in?” and “how much tax will I actually pay?” are two different questions, and this calculator is built for the first one specifically. Enter your income and filing status, and it shows exactly which 2025 federal (or state) bracket your last dollar falls into, how that compares to your effective rate, and, bracket by bracket, how much of your income sits at each rate along the way.
Marginal Rate vs. Effective Rate
Your marginal rate is the rate on your next dollar of taxable income, the bracket you’re currently “in.” Your effective rate is your total tax divided by your income: the real, blended rate you actually pay once every lower bracket is accounted for.
These two numbers are almost never equal, and the gap between them is the single most misunderstood part of how US income tax works. A common myth is that moving into a higher bracket means all your income gets taxed at the higher rate — it doesn’t. Only the slice of income that falls inside that bracket is taxed at its rate; every dollar below it stays taxed at the lower rates it always was. The bracket ladder above shows this directly: each row is a rate, an income range, and exactly how much of your income falls there.
2025 Federal Tax Brackets
| Rate | Single | Married Filing Jointly |
|---|
Example: $75,000, Single, No State Tax
Federal taxable income is $75,000 − $15,750 (2025 standard deduction) = $59,250. That amount reaches the 22% bracket, so the marginal rate is 22% — but only $10,775 of the $59,250 is actually taxed at 22%. The first $11,925 is taxed at 10% ($1,192.50), the next $36,550 at 12% ($4,386.00), and only the remaining $10,775 at 22% ($2,370.50) — $7,949.00 total, which works out to an effective rate of 13.4% on taxable income (10.6% on gross income before the deduction), well below the 22% marginal rate.
Federal vs. State Brackets
This calculator covers all 50 states. Nine have no state income tax on wages at all. Of the 41 that do, 13 use one flat rate on all taxable income (no ladder to show, since your marginal rate is just that flat rate), and 28 use their own graduated bracket system, often with very different thresholds than the federal one. Switch to the State tab once you’ve picked a state to see its own bracket ladder.
Frequently Asked Questions
What’s the difference between my marginal rate and my effective rate?
Your marginal rate is the rate on your last (highest) dollar of taxable income — the bracket you’re “in.” Your effective rate is your total tax divided by your income — the actual average rate you pay across all your income, which is always lower than your marginal rate under a progressive system.
Does moving into a higher tax bracket mean all my income is taxed at the higher rate?
No. Only the portion of your income that falls inside the higher bracket is taxed at that rate — everything below it is still taxed at the lower rates, exactly as before. The bracket ladder above shows that split explicitly.
Why don’t flat-tax states show a bracket ladder?
13 states use one flat rate on all taxable income instead of graduated brackets, so there’s no ladder to show — your marginal and effective state rate (on taxable income) end up the same number. This calculator states that directly rather than faking a bracket table for a state that doesn’t have one.
Is this the same as the US Income Tax Calculator?
It uses the same verified 2025 tax data, but this tool is built to answer a narrower question: exactly which bracket you’re in and how your income splits across brackets. For total take-home pay, FICA, and a full annual breakdown, use the Income Tax Calculator instead.
This calculator provides an estimate of your federal or state tax bracket based on the tax rules stated above. It does not model itemized deductions, tax credits, the AMT, or self-employment tax. Check the relevant government tax authority or a qualified tax professional for advice about your specific situation.
