California taxes capital gains as ordinary income — there is NO preferential rate for long-term gains. This means your stock profits, real estate gains, and crypto sales are taxed at up to 13.3%, the same as your salary. Combined with federal rates (0-20% + 3.8% NIIT), a high-income California investor can pay over 37% total on capital gains. This is a major reason tech founders and investors consider relocating before a liquidity event. Our calculator shows the full combined federal + CA tax burden on your capital gains.

Frequently Asked Questions
Does California have a lower rate for long-term capital gains?
No. California is one of the few states that taxes long-term capital gains at the same rate as ordinary income — up to 13.3%. Federally, long-term gains get preferential rates (0/15/20%), but California offers no such break.
How much total tax will I pay on capital gains in California?
A high-income Californian can pay up to 37.1% on long-term gains (20% federal + 3.8% NIIT + 13.3% CA) and up to 54.1% on short-term gains (37% federal + 3.8% NIIT + 13.3% CA).
Can I avoid California capital gains tax by moving?
Yes, but California's FTB aggressively audits 'departure year' returns. You must establish domicile in the new state before the sale and not just temporarily relocate. The FTB uses a 'closer connection' test.
Is real estate capital gains taxed differently?
Real estate gains are taxed the same as other capital gains in CA. However, you can use the federal $250K/$500K home sale exclusion (Section 121) which also applies for CA purposes.
What about the Mental Health Services surtax on gains?
Yes, the 1% Mental Health Services surtax applies to ALL taxable income over $1 million, including capital gains. So the top CA rate on gains is actually 13.3% (12.3% + 1%).
