California Tax on Capital Gains Guide – California taxes capital gains as ordinary income with no preferential long-term rates, unlike the federal system. This comprehensive guide explains the latest rules for 2025 tax year (returns filed in 2026), based on official Franchise Tax Board (FTB) sources. It helps California residents, part-year residents, and nonresidents understand their obligations, calculate taxes, and explore legal ways to minimize liability.
What Is Capital Gains Tax in California?
Capital gains arise when you sell or exchange a capital asset—like stocks, bonds, real estate, cryptocurrency, or collectibles—for more than your adjusted basis (purchase price plus improvements minus depreciation). California requires all taxpayers to report these gains and losses. Unlike the federal government, California does not offer lower rates for long-term holdings. All capital gains are taxed at the same progressive ordinary income tax rates as wages or salary.
California vs. Federal Capital Gains Tax: Key Differences
- Federal rules: Short-term gains (assets held 1 year or less) are taxed as ordinary income (up to 37%). Long-term gains (held more than 1 year) qualify for preferential rates of 0%, 15%, or 20%, depending on your taxable income. High earners may also owe the 3.8% Net Investment Income Tax (NIIT).
- California rules: No distinction between short-term and long-term. All gains are added to your taxable income and taxed at California’s ordinary income rates (1% to 12.3%, plus 1% Mental Health Services Tax on income over $1 million, for a top marginal rate of 13.3%). California generally conforms to federal rules for calculating the gain itself (basis, holding period, etc.) but applies its own tax rates.
This difference often means higher overall taxes for California taxpayers selling appreciated assets.

Short-Term vs. Long-Term Capital Gains in California
California ignores the federal holding-period distinction. A stock held for 10 years or 10 days is taxed the same way—as ordinary income at the rates above. Federally, the long-term holding period can save you thousands in taxes.
How to Calculate Your California Capital Gains Tax?
- Determine your adjusted basis (cost + improvements – depreciation).
- Subtract basis from selling price to get the gain (or loss).
- Report on federal Schedule D; carry to California Form 540.
- Add the taxable gain to your other California taxable income.
- Apply the brackets above to your total taxable income.
- Capital losses offset gains dollar-for-dollar; excess losses (up to $3,000 net per year) offset ordinary income, with carryover allowed.
Use FTB Schedule D (540) only if federal and California treatment differs.
Capital Gains Tax on Home Sales in California
California fully conforms to federal Section 121 rules. You can exclude up to $250,000 (single) or $500,000 (married/RDP filing jointly) of gain on your principal residence if you owned and lived in it for at least 2 of the last 5 years. No reporting is required if your gain is fully excluded. Gains above the limit are taxable at California ordinary income rates.
Tax on Sale of Stocks, Crypto, Real Estate, and Other Assets
- Stocks and investments: Same ordinary-income treatment.
- Cryptocurrency: Treated as property; gains are taxable.
- Real estate (non-primary): Gains are fully taxable in California unless you qualify for a like-kind (1031) exchange (California generally conforms).
- Nonresidents: Only California-source gains (e.g., California real estate) are taxable by the state.
Reporting Capital Gains on Your California Tax Return
- File federal Form 1040 + Schedule D.
- File California Form 540 (or 540NR for nonresidents).
- Use California Schedule D (540) only for differences between federal and state treatment.
- Keep detailed records of basis, purchase/sale dates, and expenses.
Strategies to Minimize California Capital Gains Tax
- Tax-loss harvesting: Sell losing investments to offset gains.
- Time your sales: Spread large gains over multiple years if possible.
- Maximize home-sale exclusion: Plan moves carefully to meet the 2-out-of-5-year test.
- Use retirement accounts: Hold assets in IRAs or 401(k)s (tax-deferred).
- Consider 1031 exchanges for investment real estate.
- Charitable contributions or donor-advised funds for appreciated assets.
- Move out of state before sale (nonresidents pay CA tax only on CA-source assets).
Always consult a tax professional; strategies depend on your full financial picture.
Special Considerations for Nonresidents and Part-Year Residents
Nonresidents and part-year residents pay California tax only on California-source capital gains (primarily real estate located in the state). FTB Publication 1100 provides detailed sourcing rules.
