Income tax in Hawaii

Hawaii has 12 brackets from 1.4% to 11%, and Act 46 — the state's largest-ever income tax cut — dramatically widened the 2025 brackets, with the 11% top rate now starting at $325,000 single / $650,000 married filing jointly. The standard deduction is $4,400 / $8,800 for 2025, with further Act 46 increases arriving in 2026. Hawaii caps the tax on long-term capital gains at 7.25%, so this estimate can overstate tax on large gains.
