Estimate only — not tax advice. This calculator gives an approximate take-home figure based on 2026 federal income tax, Social Security and Medicare (FICA), and, where shown, state income tax. It does not account for tax credits (such as the Child Tax Credit or EITC), the Alternative Minimum Tax, preferential capital-gains rates, or itemized deductions beyond the standard deduction. Your actual paycheck may differ. Consult a qualified tax professional for advice specific to your situation.
