2026 bonus tax calculator
Estimate federal supplemental withholding, FICA, and a simplified state amount on a separately paid bonus.

For a separately identified supplemental payment, employers may use the IRS percentage method: 22% up to $1 million of supplemental wages and 37% above that threshold. Social Security and Medicare can also apply. Withholding is not necessarily your final tax liability.
