Estimate net bonus pay with 22% supplemental federal withholding, FICA, and optional state tax.
Estimates only — not tax, payroll, or financial advice. This is a simplified educational calculator (2026-ish federal brackets + standard deduction, employee FICA, optional flat state tax). It is not IRS Publication 15-T withholding, a substitute for your W-4, or a tax return. Real paystubs vary with credits, benefits, local taxes, additional Medicare tax, and your employer’s payroll system. Confirm numbers with a qualified tax or payroll professional.

22% federal is only one piece. FICA (~7.65% until the SS cap) plus state tax also come out. Aggregate withholding can be higher if the bonus is stacked on a regular check.
No. Bonus net is an educational estimate — not tax, payroll, or financial advice.
