US Federal Income Tax Calculator
Calculate your US federal income tax for 2025. See your tax bracket, effective rate, and take-home pay after federal tax.
The US federal income tax uses a progressive bracket system — you don't pay one flat rate on all income. Instead, different portions are taxed at different rates (10% to 37%). This calculator shows your exact tax, effective rate, and take-home pay.
Tips for US Federal Income Tax
The US has 7 tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, 37% — you only pay the higher rate on income ABOVE each threshold
Your marginal rate (highest bracket) is NOT your effective rate — most people's effective rate is 15-22%
Standard deduction for 2025: $15,000 (single), $30,000 (married filing jointly)
This calculator shows federal tax only — state tax varies (0% in Texas/Florida, up to 13.3% in California)
