Hawaii Bonus Tax Calculator
Data compiled and maintained by Edmond Daher · Updated 2026-06-16
A Hawaii bonus feels heavily taxed, but the missing chunk is withholding, not a bonus tax. Hawaii has no separate bonus rate, so it withholds using the aggregate method on top of the 22% federal prepayment and FICA. Enter your numbers to see what's held back now beside what the bonus will really cost when you file, and your refund or amount owed. Everything runs in your browser.
The quick take: a stand-alone Hawaii bonus has a flat 22% federal tax withheld, no separate Hawaii rate — it's withheld as ordinary wages, plus 7.65% FICA. Treat it as money on account. The real tax is your marginal rate, reconciled on your return; the tool below shows the gap either way.

Cross-border check: Hawaii vs. California, Washington and Alaska on a bonus
The same $10,000 bonus and $70,000 salary, in Hawaii and its neighbors California, Washington and Alaska:
| State | Bonus method | State withheld | Total withheld |
|---|---|---|---|
| Hawaii | aggregate method | $760 | $3,725 |
| California | 10.23% / 6.6% | $1,023 | $3,988 |
| Washington | no state income tax | $0 | $2,965 |
| Alaska | no state income tax | $0 | $2,965 |
Totals stack federal 22%, state, and FICA for a single filer — the actual income tax lands when the return is filed.
How a Hawaii bonus is withheld: 22% federal + the aggregate method
How the federal 22% works. A bonus identified separately from regular wages is withheld at a flat 22% federally (IRS Publication 15). A mandatory 37% hits supplemental pay beyond $1,000,000 a year; neither figure is a special "bonus" rate, both are withholding defaults.
Hawaii: the aggregate method. Hawaii publishes no separate bonus rate, so a bonus is withheld as if it were ordinary wages. Hawaii's income tax is graduated across twelve Hawaii brackets topping out at 11%, so an aggregated bonus is withheld somewhere along that schedule.
The 7.65% FICA slice doesn't true up. Social Security and Medicare are genuine taxes on a bonus, not a prepayment. So FICA reads identically in both columns of the calculator; only the income-tax withholding settles up at filing.

A $14,000 bonus on a $215,000 Hawaii salary: withheld vs. actually owed
Say you earn $215,000 in Hawaii and your employer cuts a separate $14,000 bonus check:
- On the check: the employer holds back $3,080 for federal, $1,155 Hawaii, and $329 for FICA — $4,564 in all (32.6% of the bonus), leaving about $9,436.
- What it actually costs: the true income tax on the bonus is about $5,405 (federal $4,250 + Hawaii $1,155), plus the same $329 FICA.
- The gap: the 22% withheld falls short of your real rate, leaving about $1,170 to owe at filing. FICA ($329) stays either way — it's a real tax.

The "Hawaii bonus tax" myth, and what's really withheld
A bonus doesn't trigger a different tax — just a flat withholding up front. When you file, it's folded into your income and taxed at your marginal rate through the normal brackets. Below a 22% real rate you get money back; above it, you settle the gap at filing. For the $14,000 bonus below, the flat withholding runs roughly $1,170 light, leaving that to owe. Only FICA (7.65%) is a true tax that never returns.
Three bonus sizes in Hawaii: $5,000, $25,000 and $100,000 withheld
Three bonuses — $5,000, $25,000, $100,000 — and what Hawaii withholds from each on a $70,000 salary:
| Bonus | Federal | Hawaii | FICA | Total | % of bonus |
|---|---|---|---|---|---|
| $5,000 | $1,100 | $380 | $383 | $1,863 | 37.3% |
| $25,000 | $5,500 | $1,900 | $1,913 | $9,313 | 37.3% |
| $100,000 | $22,000 | $7,711 | $7,650 | $37,361 | 37.4% |
That percentage moves once Social Security caps out at the wage base, and the income-tax slice still settles at filing.
Hawaii bonus tax FAQ
Does Hawaii tax bonuses more than regular pay?
No. There's no separate, higher tax on bonuses — a bonus is just withheld at a flat rate up front, then taxed like any income at your marginal rate.
Do I get a refund on my Hawaii bonus?
If 22% was more than your real rate, yes — the over-withheld income tax returns at filing. If your marginal rate tops 22%, you owe the shortfall. FICA doesn't come back either way.
What is the Hawaii bonus tax rate in 2026?
Hawaii withholds the aggregate method on a separately paid bonus, on top of the flat 22% federal rate (37% above $1,000,000/yr) and 7.65% FICA. That's withholding, not your final tax.
Does Hawaii have a separate bonus withholding rate?
No. Hawaii has no separate supplemental rate, so a bonus is withheld with the aggregate method — as if it were part of your regular wages.
