Hawaii has 12 graduated brackets from 1.4% to 11%, the most brackets of any state and one of the highest top rates. Act 46 (2024) is widening brackets and raising the standard deduction in stages through 2031, cutting tax for most earners.
Note on 2026 figures: Under Act 46, the 2026 brackets carry over unchanged from 2025 (the next bracket step is 2027), and the standard deduction rises to $8,000 single / $16,000 married-jointly for 2026. Rates and thresholds shown match the Department of Taxation 2025 schedule; the standalone 2026 rate schedule had not been posted at build, so figures are marked provisional.
