Estimate what you take home.

Paycheck calculators for every state, federal tax and withholding tools, and the money calculators people use every day. Federal withholding follows IRS Publication 15-T. State pages identify the payroll method or annual tax estimate they use, with sources, examples and limits beside the calculation.

How the estimates are built

Sources and review dates

Federal figures cite IRS publications and the SSA wage base ($184,500 for 2026). The state rate inventory starts with the Tax Foundation's 2026 dataset; reviewed payroll methods cite state employer guides. Each state page lists the sources and date checked.

Tested calculations, stated coverage

Automated tests cover federal withholding examples, FICA caps and the state payroll methods implemented here. Some state pages still use an annual income-tax estimate. The result states which method applies; payroll exceptions and complete tax returns remain outside its scope.

Formulas on the page

Calculator pages explain their assumptions and show reproducible examples. Compare individual deduction lines with your paystub, and read how we calculate before using an estimate for planning.
