We built StateTax to make tax estimates easier to understand.
What StateTax is forStateTax makes tax estimates easier to understand. It brings federal, state, and payroll taxes, supported contributions, and withholding together in one clear calculator.
Planning, not filingThe calculator provides a quick estimate based on the details you enter. It is not a tax return, tax preparation service, or substitute for professional tax or financial advice.
Published tax rulesCalculations use published federal guidance, Social Security and Medicare rules, and supported state tax rates. The methodology summary beside the calculator identifies the principal official sources used.
Privacy by designYour estimate is produced locally in your browser. Calculator entries are not sent to or stored on a StateTax server.
