Crypto capital-gains 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.

Common questions

How is crypto taxed in Hawaii?
At the federal level, crypto is property and gains are taxed as short- or long-term capital gains. At the state level, Hawaii taxes crypto capital gains as ordinary income — the same rate as your wages, with no long-term discount.
Does Hawaii have a lower rate for long-term crypto gains?
No — unlike the federal system, Hawaii does not give long-term gains a preferential state rate; they're taxed the same as short-term gains.
