Hawaii Income Tax: Graduated Brackets Up to 11.0%

Hawaii uses a progressive income tax system with 12 brackets. Rates range from 1.4% to 11.0%, with higher income taxed at higher rates. Hawaii has 12 tax brackets — the most of any state — with a top rate of 11%.

Like federal taxes, Hawaii's system is marginal — only the income within each bracket is taxed at that bracket's rate. Combined with federal taxes (10%–37%), Hawaii residents can face a total marginal rate of up to 48.0% on their highest dollars of income.

Your marginal rate is the rate on your last dollar of income. Your effective rate (total tax divided by total income) is always lower because of the progressive structure.

Tips to Lower Your Hawaii Tax

Maximize pre-tax retirement contributions to reduce both federal and Hawaii taxable income. The 2026 401(k) limit is $24,500 ($32,500 with catch-up for age 50+). If Hawaii conforms to federal deductions, your standard deduction and itemized expenses also reduce your state tax liability.
