Income Tax Calculator
Estimate your federal tax, effective rate, and after-tax income.
Frequently asked questions
Which tax brackets does this use?
The official IRS federal marginal tax brackets for the tax year you select.
Standard deduction or itemized — which should I use?
The standard deduction is a flat amount based on your filing status and tax year. Itemizing totals specific deductible expenses instead — use whichever gives you the larger deduction.
Do pre-tax retirement contributions lower my taxable income here?
Yes — traditional 401(k) or IRA contributions you enter reduce the taxable income used in this estimate.
Does this include state income tax?
It includes a simplified state estimate based on an effective rate you enter (or zero for states with no income tax), not a full state-by-state bracket calculation.
