About the Federal Income Tax Calculator
The Federal Income Tax Calculator gives you an instant answer from just a few inputs — filing status, taxable income. It runs entirely in your browser, so the numbers you enter stay private and never touch a server, and the result recalculates the moment you change a value. It's free to use with no sign-up, no limits, and nothing to install.
Worth Knowing
The number this calculator reports as your "marginal tax bracket" is not the rate you pay on your whole income — it's the rate applied only to the last dollar you earned. Every dollar below that bracket is still taxed at the lower rates that came before it, which is why your effective tax rate (shown above) is always lower than your marginal bracket unless your income sits entirely in the 10% bracket. A common and costly mistake is assuming a raise or bonus that crosses into a new bracket somehow reduces your take-home pay — it doesn't, since only the portion above the threshold is taxed at the higher rate.
