California Capital Gains Tax: Rates, Rules, and What to Expect

California taxes capital gains as ordinary income — which means the same rate that applies to your wages applies to your investment profits, with no special break for long-term gains.

That's the short version. The longer version: between state and federal taxes, California residents can face a combined rate above 30% on certain gains. Here's how it breaks down and what you can do about it.

Does California Have a Lower Rate for Long-Term Capital Gains?

No. At the federal level, long-term capital gains (assets held more than a year) are taxed at preferential rates — 0%, 15%, or 20% depending on your income. California doesn't follow that rule.

The state taxes all capital gains — short-term and long-term — at the same rates as ordinary income. If you're in the top California bracket, that's 13.3% on top of whatever federal rate applies.

What Are the California Capital Gains Tax Rates?

California uses a graduated income tax, and since capital gains count as income, the same brackets apply. For 2024, the rates run from 1% at the low end to 13.3% for income over $1 million.

| California Rate | Taxable Income (Single Filers) |
|----------------|-------------------------------|
| 1% | Up to $10,756 |
| 2% | $10,757 – $25,499 |
| 4% | $25,500 – $40,245 |
| 6% | $40,246 – $55,866 |
| 8% | $55,867 – $70,606 |
| 9.3% | $70,607 – $360,659 |
| 10.3% | $360,660 – $432,787 |
| 11.3% | $432,788 – $721,314 |
| 12.3% | $721,315 – $1,000,000 |
| 13.3% | Over $1,000,000 |

Brackets for married filers are roughly double. These thresholds adjust periodically — verify the current year's figures directly from the California Franchise Tax Board (FTB).

How Does Federal Tax Stack on Top?

Federal rates depend on how long you held the asset and your total income:

• Short-term gains (held one year or less) are taxed as ordinary income — up to 37% federally.
• Long-term gains are taxed at 0%, 15%, or 20% depending on your taxable income.
• High earners with modified AGI over $200K (single) or $250K (married) also owe the 3.8% Net Investment Income Tax (NIIT) federally.

Add California's rate on top of federal, and a California resident in the top bracket selling appreciated stock could pay 23.8% federal (20% + 3.8% NIIT) plus 13.3% state — a combined 37.1%. That's before counting any other income that year.

What Triggers a Capital Gain in California?

Any sale of a capital asset at a profit. Common triggers:

• Selling stocks, mutual funds, or ETFs
• Selling a rental property or investment real estate
• Selling a business or business assets
• Selling cryptocurrency (the IRS and California both treat crypto as property)
• Selling collectibles or other appreciated personal property

Your gain is the selling price minus your cost basis — what you originally paid, plus qualifying improvements for real estate. If you've owned an asset for a long time, the basis can be well below current value, which means a larger taxable gain.

Does the Primary Home Sale Exclusion Apply?

Yes. California conforms to the federal home sale exclusion. If you've owned and used the home as your primary residence for at least two of the last five years, you can exclude up to $250,000 of gain (single filers) or $500,000 (married filing jointly).

Anything above the exclusion is taxable — both federally and in California. For a broader look at how California handles real estate taxes, how California property taxes work is worth reading alongside this.

What About a 1031 Exchange?

A 1031 exchange lets real estate investors defer capital gains by rolling proceeds from one investment property into another like-kind property. California generally conforms — but with a meaningful catch.

California's "clawback" provision (reported on Form 3840) means that if you exchange out of a California property into a property in another state, California can still tax the deferred gain when that replacement property is eventually sold. It requires annual reporting until the gain is recognized. Real estate investors should understand this before assuming a 1031 erases California's claim entirely. What landlords can deduct on their taxes covers the deduction side of the equation.

Can You Reduce What You Owe?

Several strategies people use — each requiring a tax professional's guidance for your specific situation:

Tax-loss harvesting. Selling investments sitting at a loss in the same year as a gain can offset what you owe. Capital losses first offset capital gains dollar-for-dollar; any excess can offset up to $3,000 of ordinary income per year, with the rest carrying forward.

Installment sales. For a business or real estate sale, structuring payments over multiple years spreads the gain — potentially keeping you in lower brackets each year. This requires upfront tax planning before the deal closes; restructuring after the fact is rarely possible.

Timing the sale. Selling in a year when your income is lower — after retirement, a down business year, or another major deduction — can reduce the bracket your gain falls into. It's the kind of move that requires looking a year or two ahead.

Estimated taxes. Capital gains don't have automatic withholding. If you sell a large asset mid-year, you may need to make estimated tax payments to the IRS and FTB to avoid underpayment penalties. Quarterly estimated taxes for the self-employed explains the mechanics, and estimated tax penalties covers what it costs to skip them.

For business owners selling an entity, the structure matters significantly — S-corps, LLCs, and C-corps are each taxed differently on a sale. That's a conversation worth having early with someone who handles business tax planning. Business owners who want capital gains modeled into a broader financial picture may also find value in fractional CFO services before making a major move.

What If You Owe the FTB After the Fact?

If a large gain went unreported or you underestimated what you'd owe, the FTB moves quickly on unpaid balances — including liens, levies, and wage garnishments. Getting ahead of it with a payment arrangement or penalty abatement request is almost always the better path. IRS and state tax problem help covers the resolution options available.
