2026 state supplemental (bonus) tax withholding rates
When a bonus or commission is paid separately from your regular wages, it is withheld as a "supplemental wage." Federally that is a flat 22% (and a mandatory 37% on supplemental pay over $1,000,000/year). Each state does its own thing — some publish a flat supplemental rate, most use the regular aggregate method, nine have no wage income tax, and three use a special formula. This table lists the 2026 method and rate for all 51 jurisdictions, from each state's Department of Revenue.

How to read this table
- Federal baseline
- The IRS flat rate on separately paid supplemental wages is 22% for 2026 (unchanged; the TCJA rates were made permanent by P.L. 119-21), with a mandatory 37% on any supplemental wages over $1,000,000 in the year. This is withholding, not your final tax — it trues up on your return (IRS Pub 15, 2026).
- The four state methods
- Flat — the state publishes its own flat supplemental rate, applied to the bonus when it is paid separately. Regular — no separate rate; the bonus is withheld with your ordinary wages using the state tables (aggregate method). None — the state has no wage income tax, so 0% is withheld at the state level. Special — a non-simple formula: California (two rates by pay type), Vermont (30% of the federal withholding), and Wisconsin (a four-band graduated rate).
- Only the income-tax portion is a prepayment
- The federal 22% and any state supplemental rate are withholding defaults, not a special "bonus tax." Your real tax on the bonus is your ordinary marginal rate; the withholding trues up when you file. FICA (7.65%) is not a prepayment — it is owed regardless.
- Sources
- Each state's rate is sourced to its Department of Revenue withholding guide and corroborated against an independent payroll provider (every flat/special rate passed a per-state confirmation gate). Federal figures are from IRS Publication 15 (2026). This is general information, not tax advice.
