Income tax calculator

A simplified estimate of U.S. federal income tax using marginal tax brackets. For learning and rough planning only.

Simplified estimate — not for filing: this uses recent published federal marginal tax brackets and does not account for the standard deduction being applied twice, tax credits, state/local taxes, self-employment tax, the alternative minimum tax, or FICA payroll taxes. Tax brackets are adjusted for inflation most years, so figures may not reflect the current tax year exactly. This tool should not be used to prepare or file an actual tax return — consult a tax professional or IRS.gov for authoritative figures.
