Income Tax Calculator

The US uses progressive tax brackets. You pay 10% on the first portion of income, 12% on the next, 22% on the next, and so on. Only income within each bracket is taxed at that rate.

Your marginal tax rate is the rate on your last dollar of income (your highest bracket). Your effective rate is total tax divided by total income — always lower than your marginal rate.

FICA includes Social Security tax (6.2% on income up to $168,600) and Medicare tax (1.45% on all income, plus 0.9% surcharge on income over $200,000).
