How Hawaii state tax withholding works
Hawaii taxes wage income, so your employer withholds Hawaii income tax from each paycheck in addition to federal tax. You tell your employer how much to withhold on Form HW-4 (Employee's Withholding Allowance and Status Certificate), the state’s counterpart to the federal Form W-4.
For 2026, Hawaii uses graduated tax rates. Each rate applies only to the income within its band — the single-filer schedule is:
| Rate | Taxable income over |
|---|---|
| 1.4% | $0 |
| 3.2% | $9,600 |
| 5.5% | $14,400 |
| 6.4% | $19,200 |
| 6.8% | $24,000 |
| 7.2% | $36,000 |
| 7.6% | $48,000 |
| 7.9% | $125,000 |
| 8.25% | $175,000 |
| 9% | $225,000 |
| 10% | $275,000 |
| 11% | $325,000 |
Hawaii’s standard deduction is $4,400 (single) and $8,800 (married filing jointly).

Hawaii vs. federal withholding
Your Hawaii and federal withholding are figured separately. Federal withholding follows the IRS Publication 15-T tables and your Form W-4; Hawaii withholding follows the state’s own rates and your Form HW-4. Getting one right doesn’t guarantee the other — this calculator handles both so you don’t owe a surprise bill to either the IRS or Hawaii.
Important Hawaii notes
- Hawaii has 12 brackets; standard deductions were increased under recent reforms.
