Crypto capital-gains tax in Idaho

Idaho cut its income tax rate from 5.695% to 5.3% for tax year 2025 via House Bill 40, made retroactive to January 1, 2025 — the largest income tax cut in state history. The tax is effectively flat: 5.3% applies to taxable income above a small zero-rate band ($4,673 single / $9,346 married filing jointly), after a standard deduction that mirrors the federal amounts. Capital gains are taxed as ordinary income.

Common questions

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