Hawaii income tax goes up to 11% at the top bracket. Calculate your combined federal + state effective tax rate for 2026. Formula shown, sources cited — no account required.
The state uses a graduated income tax structure with rates that climb from a low of 1.4% to a top marginal rate of 11.0% — the highest state income tax rate in the country. For a median-income household earning $100,745, state tax alone can represent a meaningful four-figure annual payment before federal taxes apply. Federal and state brackets do not mirror each other, so a taxpayer may face different marginal rates at each level simultaneously. One notable feature is that the state allows a standard deduction and personal exemption, which reduce taxable income slightly before rates apply. There is no special deduction for retirement account contributions beyond federal rules, but the exclusion of Social Security from state tax provides relief for older filers. High earners, particularly those in finance, real estate, and healthcare, face the steepest combined federal-plus-state burden of any US state.

Hawaii's High State Taxes: Federal + State Brackets Explained (2026)
Hawaii has a state income tax with a top marginal rate of 11%. On top of federal rates (10%–37%), residents can face a combined marginal rate exceeding 40% at higher income levels. However, your effective rate is always lower than the marginal rate because only income above each threshold is taxed at that bracket's rate.
The median household in Hawaii earns $100,745/year. At that income (single filer), the federal effective rate is approximately 12–14%, bringing total income tax (federal + state) to roughly 19–22%.
How Marginal vs. Effective Rate Works
The marginal rate is the rate on your last dollar of income — it does not apply to all income. The effective rate is your total tax divided by total income. For example, someone earning $100,000 in Hawaii has a 22% federal marginal rate but an effective federal rate of roughly 15%, because the first $44,725 (2024) is taxed at 10% and 12%, not 22%.
