Hawaii State Income Tax Overview
Hawaii has the highest top marginal state income tax rate among all states at 11%, which applies to income above $200,000 for single filers. Hawaii uses a graduated system with twelve brackets beginning at 1.4% on income up to $2,400. The standard deduction in Hawaii is $2,200 for single filers and $4,400 for married couples — among the lowest in the country. Hawaii does not conform to many federal tax provisions, so residents must recalculate certain items under state rules. Hawaii also imposes a General Excise Tax in lieu of a traditional sales tax, which is effectively passed on to consumers at rates ranging from 4% to 4.5%.
Hawaii Income Tax Brackets (2026) projected
These are the Hawaii state income tax brackets for single filers, carried forward from 2025 pending official 2026 figures. Only the income within each bracket is taxed at that rate -- not your entire income.

Understanding Your Hawaii Tax Estimate
Your results combine two separate bills: federal tax owed to the IRS, and Hawaii state tax owed to the Hawaii Department of Taxation. The state return is filed separately from your federal Form 1040, with a state filing deadline of April 20. For the mechanics of how bracket math actually works -- why your effective rate is almost always lower than your top bracket -- see our marginal vs. effective tax rate guide.
Lowering Your Hawaii Bill
Pre-tax retirement contributions reduce your federal and Hawaii taxable income in the same move -- see our 401(k) contribution limits and HSA limits guides for the current caps. Beyond that, Hawaii-specific credits and deductions that don't exist at the federal level are listed at the Hawaii Department of Taxation -- worth checking, since these are easy to miss if you only look at federal guidance.
Combined Sales + Income Tax Picture
Hawaii's combined state-plus-average-local sales tax rate is 4.44%. If you're self-employed, that's an added layer on top of income tax -- our self-employment tax calculator covers the SE-specific piece separately.
