What Is an Income Tax Calculator?

How Income Tax Works
Income tax is usually based on taxable income. Taxable income is generally gross income minus eligible deductions and pre-tax contributions. Many systems use progressive brackets, meaning different portions of income are taxed at different rates.
Income Tax Calculator Formula
The calculator estimates federal tax using simplified brackets, then adds state or local tax estimates and optional other taxes. Tax credits are subtracted from the estimated federal tax.
Taxable Income vs Gross Income
Gross income is your total income before deductions. Taxable income is the amount used to estimate income tax after subtracting deductions and pre-tax contributions. Take-home pay is what remains after estimated taxes.
