California capital gains tax overview

California taxes capital gains as ordinary income with no preferential rate. The top 13.3% rate applies above $1,000,000 (single). Ten brackets total.

No preferential long-term rate: Unlike the federal system, California taxes capital gains identically to ordinary income at the state level. This makes timing strategies especially important for California residents with large gains.

Federal + California combined rates

Your total capital gains tax bill includes both layers — federal and state. Here is what a California investor pays in 2026 for long-term gains:

15%13.30%28.3%32.1%
20%13.30%33.3%37.1%

The NIIT (Net Investment Income Tax) adds an extra 3.8% for taxpayers whose MAGI exceeds $200,000 (single) or $250,000 (married filing jointly). It is a federal tax only — California does not have an equivalent.

Detailed California capital gains tax rules

Tax history and legal basis

California has taxed capital gains as ordinary income since its personal income tax was established in 1935. It has never offered a preferential rate for long-term gains.

Exemptions and special treatment

California offers a partial exclusion for Qualified Small Business Stock (QSBS) under R&TC §18152.5 — up to 50% of gain from qualifying CA small business stock held 5+ years. There is no general long-term capital gains exclusion. The $250k/$500k federal home sale exclusion (Section 121) applies to reduce the gain before CA taxes it.

Filing requirements

File Form 540 (resident) or 540NR (non-resident/part-year). California requires estimated tax payments if you expect to owe $500+ after withholding. Mental Health Services Tax (1% surcharge) applies to taxable income over $1 million, bringing the effective top rate to 14.4%.

Recent changes and legislative updates

California's top rate of 13.3% (plus 1% Mental Health surcharge above $1M) remains the highest state income tax rate in the nation. There have been multiple ballot proposals to increase taxes on high earners further, though none passed in 2024. The state's Franchise Tax Board (FTB) aggressively audits residency claims of taxpayers who move to no-tax states.

Worked example: $50,000 capital gain in California

Here's exactly what a California resident would owe on a $50,000 long-term capital gain with $80,000 in other income (single filer, 2026):

ComponentAmountNotes
Capital gain$50,000Long-term (held over 1 year)
Federal tax (15%)−$7,500Based on $80,000 ordinary income + gain
California state tax (9.3%)−$4,650Applied to the full gain amount
Total tax owed−$12,150Federal + state combined
You keep$37,85075.7% of your gain

After both federal and California state tax, you keep $37,850 of your original $50,000 gain. The effective combined rate is 24.3%. This is significantly higher than the national average — consider tax-loss harvesting or timing strategies to reduce your bill.

Frequently asked questions — California

Does California tax short-term and long-term gains differently?

No — California taxes both short-term and long-term capital gains as ordinary income at the same rates as wages. There is no state-level preferential rate for patience. The federal system, however, taxes long-term gains at 0/15/20% vs. up to 37% for short-term — a significant difference that applies regardless of state.

Do I need to file a California tax return if I only have capital gains?

If you have capital gains income and meet California's filing threshold, you are required to file a California state income tax return. The threshold is typically similar to the standard deduction amount — check the CA Department of Revenue for the current year's filing requirements.

What if I moved to California mid-year?

If you moved to California during the year, you are a part-year resident. California generally taxes capital gains realized while you were a California resident. Gains realized before you moved may be taxable by your prior state. Keep detailed records of when each sale occurred relative to your move date.
