StateTaxLab

Independent, free, in-browser US paycheck and state-tax calculator. Pick a state, enter pay, and see where each dollar goes after federal and state tax, with the rule and official source behind each deduction. Updated for 2026 and 2027. Nothing typed is sent to the server.

It is for employees, job-switchers, and anyone who wants to see why a paycheck looks the way it does, not just a single take-home number. Figures come from the IRS, SSA, and state tax agencies. Dedicated calculators cover 19 states so far, with more added weekly; if a state is not listed yet, federal income tax, Social Security, and Medicare are still available. Related tools cover the federal “no tax on overtime” and “no tax on tips” deductions, plus federal tax brackets and the standard deduction.

The site is not affiliated with the IRS, any state tax agency, or any payroll company. Results are estimates for planning, not tax, legal, or financial advice. All math runs in the browser; nothing typed is sent to the server.
