Short answer
- California does not give a special low rate for capital gains. For California income-tax purposes capital gains (long‑term and short‑term) are treated as ordinary income and taxed at the same progressive state rates as wages and other income.
Key details
- No preferential state rates: Unlike federal tax (which has 0/15/20 long‑term rates), California has no separate long‑term capital gains rate — gains are included in your taxable income and taxed at the same brackets as other income.
- Marginal rates: California’s individual income tax rates are progressive and currently top out at 13.3% for the highest incomes. (Bracket thresholds change year to year.)
- Federal + state: You pay both federal and California tax on gains. That means your total tax on a long‑term gain could be roughly federal long‑term rate (0/15/20%) + 3.8% NIIT if it applies + California state rate (up to 13.3%). Rough examples: long‑term gain for a top taxpayer ≈ 20% + 3.8% + 13.3% ≈ 37.1% combined; a short‑term gain taxed as ordinary income for a top taxpayer could be as high as ~54% (37% federal + 3.8% NIIT + 13.3% CA), roughly adding the rates together for intuition.
- Residents vs nonresidents: California residents are taxed on worldwide income (including capital gains). Nonresidents are taxed only on California‑source income — e.g., gains from sales of California real estate or gains attributable to a business in California. Sales of intangible property (like stock) are generally sourced to the seller’s state, so a nonresident selling stock typically won’t owe CA tax just because the company is headquartered in California.
- Flow‑through entities: Capital gains passed through from partnerships, S corps, LLCs, etc., are taxed to the owners on their California returns at ordinary rates if they are California residents (or if the gains are California‑source for nonresidents).
- Special items and deferrals: Federal rules such as the principal residence exclusion (up to $250K/$500K) generally affect California taxation similarly, and like‑kind exchange deferral for real property follows federal law. There are some conformity differences and technical exceptions — check specifics for real estate, collectibles, depreciation recapture, etc.
- Capital losses: Net capital losses are treated under the same general rules for California taxable income, but carryover and certain treatment details can differ from federal rules in some cases — consult tax guidance for your year.
If you want, I can:
- Run a concrete example with your income and gain to show estimated combined federal+CA tax,
- Explain sourcing rules for nonresidents in more detail, or
- Point you to relevant California FTB guidance or code sections.
