# Signing bonus after taxes (2026)

A signing bonus is usually supplemental wages, not a second salary. Google suggests “signing bonus after taxes” and “signing bonus after tax calculator.” This page preloads an $80,000 salary plus a $10,000 signing bonus so you can see regular take-home plus the supplemental sketch. It is not a second copy of the national bonus calculator.

Federal withholding on a signing bonus often uses the IRS optional flat 22% on supplemental wages (37% on supplemental wages over $1,000,000). Employers may instead use the aggregate method on a combined check. This engine shows the flat supplemental sketch for planning cash, not filing a return.

FICA still applies. Social Security stops at the $184,500 2026 wage base; Medicare does not. California adds a simplified PIT increment plus 1.3% SDI on the bonus in this model. Texas zeros the state income-tax line on the same $10,000 bonus.

Use the national bonus calculator if you only care about the supplemental field, or the California-with-bonus page for a CA-first layout. Reviewed October 2, 2026.
