California Crypto Tax: State Rates, Rules & Calculator
Everything California crypto holders need: how your gains are taxed at the state level, a worked example, the cities we cover, and free tools to calculate exactly what you owe.
How crypto is taxed in California
California follows California's graduated state income tax. Crypto gains realized while you are a California resident are taxed as income at the state level — with a top marginal rate of about 13.3% — on top of federal capital gains tax. California has the highest top marginal income-tax rate in the US (13.3%) and taxes crypto gains as ordinary income, with no special long-term rate.
Worked example: on a $10,000 long-term crypto gain, a California resident could owe roughly $1,500 federally (15% long-term bracket) plus up to about $1,330 to California at the top marginal rate — a combined ballpark of $2,830. Your real rate depends on your total income.
However it is taxed where you live, the federal rules are the same: the IRS treats crypto as property, every sell or swap is a taxable event, gains held one year or less are short-term (ordinary income) and gains held longer are long-term (0%, 15%, or 20%). Losses offset gains and up to $3,000 of ordinary income per year.
