How crypto is taxed in San Diego, CA
San Diego, CA 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.
