About this tool

NetPay Atlas shows 2026 take-home pay after federal, state and FICA taxes for every US state. W-4 settings, pre-tax 401(k) and health insurance deductions are each shown as their own line, so users can see where each dollar of a paycheck goes. It runs in the browser with no signup, no email and no ads inside the calculator, and results were checked against 130 same-input cases before launch. It is an estimate, not payroll software.
