NetPay Atlas

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 rather than a single total. It runs in the browser with no signup, no email and no ads inside the calculator, and its results were checked against 130 same-input cases before launch. It is an estimate, not payroll software — an employer's payroll system remains the source of truth.
