# California paycheck calculator with bonus (2026)

California employees often get a bonus on a separate check. This page preloads California, an $80,000 salary, and a $10,000 bonus so you can see regular take-home plus the supplemental sketch already in the product.

Federal bonus withholding here uses the IRS optional flat 22% on supplemental wages, or 37% on supplemental wages over $1,000,000. Employers may instead use the aggregate method on a combined check. This is a planning sketch, not a stub.

FICA applies to bonus wages. Social Security stops at the $184,500 2026 wage base; Medicare does not. California income tax gets a simplified increment, and EDD SDI (1.3%, no cap) applies to the bonus in this model.

If the bonus field is empty after you share a bare URL, type the bonus in the calculator — the field is the same one on the national bonus page. Reviewed August 24, 2026.
