California taxes capital gains as ordinary income with no preferential rate for long-term gains. This makes California one of the most expensive states for investors and property sellers, with a top combined federal-plus-state rate that can exceed 37% on long-term capital gains. For anyone selling stock, real estate, or a business in California, understanding how the state taxes gains — and what strategies are available — is essential.
California Capital Gains Tax Rates (2026)
California does not distinguish between short-term and long-term capital gains at the state level. All capital gains are added to your ordinary income and taxed at your marginal income tax rate.
| Tax Rate | Taxable Income Range (Single) |
|---|---|
| 1.00% | $0 — ~$10,756 |
| 2.00% | ~$10,757 — ~$25,499 |
| 4.00% | ~$25,500 — ~$40,245 |
| 6.00% | ~$40,246 — ~$55,866 |
| 8.00% | ~$55,867 — ~$70,606 |
| 9.30% | ~$70,607 — ~$360,659 |
| 10.30% | ~$360,660 — ~$432,787 |
| 11.30% | ~$432,788 — ~$721,314 |
| 12.30% | ~$721,315 — ~$1,000,000 |
| 13.30% | Over ~$1,000,000 |
The 13.30% top rate includes the 1% Mental Health Services Tax (Proposition 63) on income exceeding $1 million.
Combined Federal + California Rate on Long-Term Gains
| Income Level | Federal Rate | CA State Rate | NIIT | Combined |
|---|---|---|---|---|
| Below ~$48,350 | 0% | ~1%—4% | — | ~1%—4% |
| ~$48,351 — ~$533,400 | 15% | ~9.3%—12.3% | 3.8%* | ~24.3%—31.1% |
| Over ~$1,000,000 | 20% | 13.30% | 3.8% | ~37.1% |
NIIT applies to taxpayers with MAGI above $200,000 (single) or $250,000 (MFJ).
How It Works
No Preferential State Rate
The federal tax code provides lower rates for long-term capital gains (0%, 15%, or 20%). California does not follow this treatment. At the state level, a $500,000 long-term gain is taxed identically to $500,000 of salary income. This is the single most important distinction for California investors to understand.
Primary Residence Exclusion
California conforms to the federal exclusion of up to $250,000 (single) or $500,000 (married filing jointly) in capital gains from the sale of a primary residence, provided you have lived in the home for at least two of the past five years. Given California’s high home values, many homeowners with gains exceeding these thresholds face substantial state tax obligations.
1031 Exchange Conformity
California generally conforms to federal 1031 like-kind exchange rules, allowing deferral of gains on the sale of investment real estate when proceeds are reinvested in qualifying replacement property. However, if you do a 1031 exchange and then move to another state before selling the replacement property, California may claw back the deferred gain (Form 3840 is used to track deferred gains from California 1031 exchanges).
Installment Sales
Spreading a sale over multiple years through an installment agreement can keep income in lower brackets. California conforms to federal installment sale rules, allowing gain to be recognized proportionally as payments are received.
Comparison to National Average
| Metric | California | Typical State |
|---|---|---|
| State capital gains rate | Up to 13.30% | ~0%—5% (most states) |
| Long-term preferential rate | None | Most states follow federal |
| Primary residence exclusion | Yes (federal conformity) | Yes (most states) |
| 1031 exchange | Yes (with clawback tracking) | Yes (most states) |
California’s treatment of capital gains as ordinary income at rates up to 13.30% is the harshest in the nation. Most states either follow the federal preferential rate, impose a flat rate, or have no income tax at all.
Tips for Minimizing California Capital Gains Tax
- Use the primary residence exclusion. Ensure you meet the two-out-of-five-year residency test before selling. For married couples, the $500,000 exclusion can shelter significant gains in high-value markets.
- Consider your residency timing carefully. California aggressively taxes former residents on California-source gains. If you plan to move out of state before selling assets, consult a tax professional about “safe harbor” rules and the date of sale versus the date of gain recognition.
- Harvest losses to offset gains. California conforms to federal capital loss rules. You can offset gains with losses and deduct up to $3,000 in net capital losses against ordinary income per year.
- Spread gains through installment sales. For business or real estate sales, structuring the transaction as an installment sale can keep income in lower brackets across multiple years.
- Donate appreciated assets. Donating stock or property held more than one year to a qualified charity avoids both federal and state capital gains tax on the appreciation, while providing a fair market value deduction.
- Track 1031 exchange obligations. If you defer gain through a 1031 exchange, California requires annual reporting on Form 3840. Failing to file can trigger penalties.
- Maximize retirement account contributions. Gains within IRAs, 401(k)s, and other qualified accounts are not subject to state capital gains tax until withdrawal (or never, in the case of Roth accounts).
