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.
