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.
