How Bonuses Are Taxed in Hawaii (2026)
A bonus paid on a separate check in Hawaii has a flat 22% federal tax withheld (37% on cumulative supplemental wages over $1,000,000 in a year), 7.65% FICA, and Hawaii state income tax at your marginal rate. Withholding is not a higher tax rate — it is just how much your employer holds back up front; your actual tax on the bonus is settled when you file, and any over-withholding comes back as refund.
| Component | Rate on the bonus |
|---|---|
| Federal income tax (supplemental, percentage method) | 22% flat · 37% above $1,000,000/yr |
| Social Security | 6.2% (up to $184,500 of total wages) |
| Medicare | 1.45% · +0.9% above $200,000 |
| Hawaii state tax | Your marginal bracket rate |
Some employers instead use the aggregate method — adding the bonus to your regular paycheck and withholding as if that were every check — which can withhold more or less than the flat 22%. The calculator above uses the flat-rate (percentage) method.

Does this estimate change if I'm married or have dependents?
This calculator uses single-filer figures only (v1 scope).

Dependents can also reduce federal withholding via the W-4. Check Hawaii Department of Taxation's married-filing-jointly tables for a precise figure.
Methodology & Source
Hawaii state tax figures sourced from Hawaii Department of Taxation (https://files.hawaii.gov/tax/), citing Haw. Rev. Stat. § 235-51 — 12-bracket schedule; standard deduction $8,000 per Act 46 2026 phase-in step. Federal brackets, standard deductions (single/MFJ/HoH), and FICA constants sourced from the IRS (Revenue Procedure 2025-32; married-filing-jointly Additional Medicare threshold of $250,000 is a separate, unindexed statutory figure). Hawaii's married-filing-jointly and head-of-household figures are not yet independently verified and currently fall back to single-filer brackets — see the caveat in the formula section above.
Bonus federal withholding uses the flat supplemental-wage rate (22%, 37% above $1,000,000 cumulative supplemental wages/year), per IRS Publication 15 (Circular E), Employer's Tax Guide, 2026 edition — the alternative "aggregate method" is not modeled. Hawaii publishes no separate supplemental withholding rate, so the calculator estimates the state tax on the bonus from your marginal bracket.
This is an estimate based on standard single-filer federal, FICA, and HI state calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions, and other factors.
