Tax Bracket Calculator
See exactly how much federal tax you owe at each bracket.
ℹ️À propos de cette Calculatrice
The US federal income tax uses a progressive system — you don't pay one flat rate on all income. Instead, each portion of your income is taxed at the rate for that bracket. This calculator shows exactly how much tax applies at each level so you can see your true effective rate versus your marginal (highest) rate.
Questions Fréquentes
What is a marginal vs. effective tax rate?
Your marginal rate is the tax rate on your last dollar of income — the highest bracket you reach. Your effective rate is total tax divided by total income, which is always lower because earlier dollars are taxed at lower rates.
What is the standard deduction for 2025?
For 2025 the standard deduction is $15,000 (single), $30,000 (married filing jointly), and $22,500 (head of household). If your itemized deductions exceed these amounts, itemizing saves you more.
Does this include state taxes?
No — this calculates federal income tax only. State taxes vary widely (some states like Texas and Florida have none). Add your state tax separately for a complete picture.
