Washington's Unique Tax Situation
Washington State has no personal income tax — but the state Supreme Court upheld the Washington Capital Gains Tax in 2023. This tax applies a 7% rate to long-term capital gains exceeding the annual standard deduction (adjusted annually; approximately $262,000 for 2026).
For most Washington crypto holders with moderate gains, this threshold means the state capital gains tax doesn't apply. For those with large crypto positions and significant realized gains, it can add a meaningful state-level tax.
Rate: 7% on long-term capital gains exceeding the annual threshold (~$262,000 in 2026). Gains below the threshold: 0% WA state tax. No WA state income tax on wages or short-term gains (those are federal only). Verify current thresholds at the WA Department of Revenue: dor.wa.gov.
Does the WA Capital Gains Tax Apply to Crypto?
Yes. The Washington capital gains tax applies to long-term capital gains from the sale of assets including cryptocurrency. "Long-term" means held for more than one year — the same federal definition. Short-term gains (held under 12 months) are not subject to Washington's capital gains tax, since it applies only to long-term gains.
This means: if you held Bitcoin for 18 months and sell at a profit of $300,000, Washington may tax approximately $38,000 of that (the amount above the ~$262,000 threshold) at 7%, for a state tax of ~$2,660 in addition to federal taxes.
Washington Has the Highest Crypto Adoption Rate in the US
Washington State has the highest crypto ownership rate per capita in the United States — approximately 2.43% of residents own cryptocurrency, above the national average. The Seattle-Bellevue metro area's concentration of tech companies (Amazon, Microsoft, Boeing's tech operations) correlates with higher income, higher tech literacy, and higher crypto adoption.
What Counts as a Taxable Event
Same federal framework: selling crypto for USD, trading one coin for another, spending crypto. The WA capital gains tax only applies to long-term gains above the annual threshold. Federal taxes apply to all gains as they normally would.
Short-term crypto gains (held under 1 year) are not subject to the WA capital gains tax — but they are subject to federal ordinary income tax.
FAQ
Does the WA capital gains tax apply to small crypto gains?
No. The Washington capital gains tax only applies to long-term gains exceeding the annual standard deduction (approximately $262,000 in 2026, adjusted annually for inflation). Most beginning crypto investors with small positions will not reach this threshold. Federal taxes still apply to all gains regardless.
Is Washington still better than California for crypto taxes?
For most crypto holders, yes. California taxes all capital gains as ordinary income (up to 13.3%) with no threshold. Washington only applies a 7% rate on long-term gains above ~$262,000. For gains under that amount: Washington has a 0% state tax. For gains above the threshold: Washington (7%) is lower than California's top rate (13.3%).
Does Washington tax crypto mining or staking income?
Washington has no state income tax, so mining and staking income received as ordinary income is not subject to WA state tax. It is subject to federal ordinary income tax. The WA capital gains tax applies to gains from the eventual sale of assets — not to income received.
