How to Use the Federal Income Tax Estimator
The US uses a progressive income tax system, meaning your tax rate increases as your income levels rise through different tax brackets. Your marginal tax rate is the tax rate applied to your last dollar of income, whereas your effective tax rate is the actual percentage of your total income paid in taxes after standard or itemized deductions.
