California capital gains tax is simpler than it first looks, but the headline “13.3% capital gains rate” is misleading. California does not have a separate long-term capital-gains tax schedule. It generally adds taxable capital gains to your other California taxable income and applies the state’s ordinary income-tax rates.
That means a long-term stock gain can receive a lower federal rate while California taxes the same gain just like other taxable income. High earners can also face California’s additional 1% Behavioral Health Services Tax on taxable income above $1 million.
The practical question is not “What is California’s capital gains rate?” It is how much additional California tax does this gain create after it is stacked on top of the rest of your income?
Show the quick version
- State treatment: California does not give long-term capital gains a special lower state rate. Taxable gains are generally taxed as ordinary income.
- Top rate: The regular personal-income-tax schedule tops out at 12.3%. An additional 1% Behavioral Health Services Tax applies to taxable income above $1 million, creating a maximum 13.3% marginal state rate.
- 2026 planning: As of September 22, 2026, FTB's public tax tables and rate schedules are still 2025. Its 2026 estimated-tax instructions tell taxpayers to use the 2025 table for estimating 2026 tax.
- Federal tax: Federal treatment is separate. Long-term gains may receive 0%, 15%, or 20% federal rates, and some taxpayers also owe the 3.8% NIIT.
- Residency: Moving out of California is not a magic six-month trick. Stock and other intangible gains generally follow residency at sale, while California real property and some deferred California-source gains can remain taxable by California.

How California Capital Gains Tax Actually Works
The California Franchise Tax Board states the rule plainly: California does not have a lower rate for capital gains. Long-term and short-term gains are generally taxed through the regular personal-income-tax system.
This is the first place people get tripped up. Federal tax law cares a lot about whether you held an investment for more than one year. California generally does not give you a lower state rate just because the gain is long term.
Think of a California gain as another floor added to your income stack. The gain sits on top of the taxable income you already have. The higher that stack goes, the higher the marginal California rate on the top slices can become.
I saw this distinction confuse investors for years. Someone would hear “15% long-term capital gains” and assume the entire tax picture was 15%. That is only a federal shorthand. California can add another layer, and the 3.8% federal Net Investment Income Tax can add a third layer for some households.
- California income tax. The taxable gain is added to California taxable income and runs through California’s progressive rate schedule.
- California Behavioral Health Services Tax. The portion of taxable income above $1 million gets an additional 1% California tax.
- Federal tax. Federal short-term or long-term capital-gains rules apply separately, and the 3.8% NIIT may also apply.
California Capital Gains Tax Rates for 2026 Planning
There is an important timing wrinkle as we head toward the end of 2026. As of September 22, 2026, FTB’s public tax calculator and published rate schedules still show 2025 as the latest final schedule. FTB’s own 2026 estimated-tax instructions tell taxpayers to figure estimated 2026 tax using the 2025 tax table.
That makes the 2025 schedule the best official planning baseline today, but it is not the same thing as pretending the final 2026 bracket cutoffs have already been published.
For single filers and married/RDP taxpayers filing separately, the latest official schedule is:
| 2025 California taxable income | Marginal rate |
|---|---|
| $0 to $11,079 | 1% |
| $11,079 to $26,264 | 2% |
| $26,264 to $41,452 | 4% |
| $41,452 to $57,542 | 6% |
| $57,542 to $72,724 | 8% |
| $72,724 to $371,479 | 9.3% |
| $371,479 to $445,771 | 10.3% |
| $445,771 to $742,953 | 11.3% |
| Over $742,953 | 12.3% |
Married/RDP joint and head-of-household schedules use different thresholds. The calculator below includes those latest official schedules too.
The regular California schedule tops out at 12.3%. The additional 1% Behavioral Health Services Tax applies to taxable income above $1 million. So 13.3% is a maximum marginal state rate, not a special capital-gains bracket that applies to every gain.
California Capital Gains Tax Calculator: Estimate the Added State Tax
A useful California capital-gains calculator has to apply the gain to the tax calculation, not just calculate tax on the income you already had. The calculator below estimates the incremental California income tax created by adding a taxable gain to your other California taxable income.
How much California tax could this gain add?
Estimate the incremental California income tax created by a standard taxable capital gain. California does not give long-term gains a special lower state rate.
2026 planning note: FTB's current public rate schedules are still the official 2025 schedules, and the 2026 estimated-tax worksheet tells taxpayers to use the 2025 tax table for estimating 2026 tax. This tool uses those latest official schedules for planning and should be refreshed when FTB publishes the final 2026 schedules.
This is the estimated increase in California income tax from adding the gain to the taxable income you entered.
What this estimate does not include
- Federal capital-gains tax or the 3.8% NIIT.
- Home-sale Section 121 exclusions, depreciation recapture, 1031 exchanges, QSBS, or California/federal basis differences.
- Credits, AMT, special deductions, capital-loss netting, withholding, penalties, or transaction-specific sourcing rules.
- A final 2026 California rate schedule that FTB has not yet published.
The calculator intentionally does not try to become a federal tax return. For a broader federal capital-gains explanation, use my capital gains tax guide.
Federal vs. California Capital Gains Tax: The Same Gain Can Be Treated Two Ways
Federal law still distinguishes short-term from long-term gains. Most long-term capital gains use the 0%, 15%, or 20% federal structure, while short-term gains generally fall into ordinary federal income-tax rates. The 3.8% Net Investment Income Tax can also apply when MAGI exceeds its statutory threshold.
California generally ignores that federal long-term-rate discount. If California recognizes the gain, it goes into the state ordinary-income calculation.
Holding an investment longer than one year can still be very valuable because of federal tax treatment. But do not expect the holding period by itself to create a lower California state rate.
How Can You Reduce Capital Gains Tax in California?
There is no single California loophole that erases a large gain. The useful planning moves generally fall into four buckets.
1. Use legitimate capital losses
Capital losses can offset capital gains under the applicable federal and California rules, although California and federal basis or conformity differences can create adjustments. Tax-loss harvesting can be useful when it is driven by the investment and tax facts, not merely by a desire to manufacture a deduction.
2. Compare the gain across different income years
Because California stacks gains on top of other taxable income, the same gain can create a different state-tax cost in a year when your other taxable income is lower. This is especially relevant around retirement, sabbaticals, business-sale years, large bonuses, option exercises, and other unusually lumpy income.
This is a modeling question, not a rule that says “always delay the sale.” Market risk, diversification, cash needs, federal tax, and the possibility of future law changes still matter.
3. Consider charitable planning before the sale when it already fits your goals
Donating appreciated assets directly to a qualified charity or using a properly structured charitable vehicle can change the tax result, but the economics only make sense when the charitable gift itself is something you genuinely want to make. A tax deduction does not turn away a dollar of wealth loss into free money.
4. Remember where the investment is held
Taxable brokerage accounts, traditional retirement accounts, Roth accounts, and other wrappers can produce very different tax consequences. A gain inside a tax-deferred or tax-free retirement account is not taxed the same way as a sale in a normal taxable account. Account choice belongs in the broader investment plan, not as a last-minute reaction after a gain already exists.
Does Moving Out of California Avoid Capital Gains Tax?
Sometimes. But this is where the internet’s “move for six months and sell” advice becomes dangerous.
California residency is a facts-and-circumstances question. For stocks and other intangible personal property, gain is generally sourced to the taxpayer’s residence at the time of sale. FTB examples show that a qualifying stock gain realized after a genuine move out of California can be sourced outside California.
But California real property is different. Gain from California real estate remains California-source income even when the seller is a nonresident. Deferred gain can also carry California reporting or sourcing consequences. FTB’s Publication 1100 is the better starting point than a residency rule of thumb.
A calendar count alone does not prove that you stopped being a California resident. If a move is being coordinated around a major sale, document the real change in domicile and verify how the specific asset is sourced before assuming California is out of the picture.
What About Capital Gains on a California Home?
California generally conforms to the federal main-home exclusion rules. A qualifying homeowner may exclude up to $250,000 of gain, or up to $500,000 on a qualifying joint return. The ownership, use, prior-exclusion, rental, depreciation, and reporting rules can make that calculation more complicated than the state-rate question on this page.
That is why the full home-sale job belongs in my capital gains tax on a home sale guide rather than being duplicated here.
Three California Traps the Old Advice Often Misses
1. Federal Opportunity Zone tax treatment does not automatically carry to California
California does not conform to the federal capital-gain deferral and exclusion rules for Qualified Opportunity Zone funds. That means a strategy that changes federal tax can still leave a California tax bill.
2. A 1031 exchange does not necessarily make California forget the old property
California generally recognizes qualifying Section 1031 deferral for real property, but a California property exchanged for out-of-state replacement property can carry a California filing trail. California requires annual information reporting in certain deferred-gain situations until the gain is eventually recognized.
3. California can differ from federal law on special assets
California does not conform to every federal capital-gain preference. One important example is federal qualified small business stock treatment under Sections 1045 and 1202. This is why a California calculation should not simply take the federal taxable gain and assume every special rule carries over unchanged.
How Does California Tax Crypto Gains?
For this page’s purpose, crypto is not a separate California rate system. A taxable capital gain from selling or exchanging crypto generally feeds into the same California capital-gain and ordinary-income framework. Federal holding-period rules can still change the federal result, but California does not create a lower state rate merely because a crypto gain is long term.
The practical challenge with crypto is often records. Frequent trades, transfers between wallets, missing basis records, and taxable exchanges can make the gain calculation harder long before the California rate becomes the main problem.
California Capital Gains Example: Why the Marginal Rate Is Not the Whole Bill
Suppose a single California taxpayer has $100,000 of California taxable income before selling an investment and realizes a $50,000 taxable gain.
The $50,000 is not simply multiplied by 9.3% or 13.3%. Instead, the gain is stacked on top of the existing $100,000 and the incremental California tax is the difference between the tax on $150,000 and the tax on $100,000 under the applicable schedule.
That is exactly why I rebuilt the calculator on this page around the tax before versus tax after method. It mirrors the decision you are actually trying to make.
California Capital Gains Tax FAQ
Does California have a separate long-term capital gains tax rate?
No. California generally taxes long-term and short-term capital gains through the ordinary state income-tax schedule. The holding period can still matter greatly for federal tax.
Is California’s capital gains tax really 13.3%?
13.3% is the maximum marginal California personal-income-tax rate after combining the 12.3% top regular rate with the additional 1% Behavioral Health Services Tax on taxable income above $1 million. It is not a flat 13.3% tax on every capital gain.
Are the final 2026 California tax brackets available yet?
As of September 22, 2026, FTB’s public tax calculator and rate-schedule page still list 2025 as the latest final schedule. FTB’s 2026 estimated-tax worksheet instructs taxpayers to use the 2025 tax table for the estimate. This page should be refreshed when the final 2026 schedule is published.
Does California tax capital gains if I move to Nevada, Texas, or Florida?
It depends on whether you actually became a nonresident and what asset produced the gain. Stock and other intangible gains often follow residency at sale. California real property generally remains California-source income, and deferred California gains can have continuing state consequences.
Does California follow the federal home-sale exclusion?
Generally, yes. California allows the main-home exclusion under rules that substantially track the federal Section 121 framework. The dedicated home-sale article covers the ownership, use, partial-exclusion, rental, depreciation, and reporting details.
My Take: Model the Gain, Not the Headline Rate
California’s capital-gains system gets described as complicated because people mash federal and state rules together. The California part is easier to understand once you separate it.
First determine the gain California actually taxes. Then stack that gain on top of the rest of your California taxable income. Then calculate the state-tax difference. Only after that should you layer in federal capital-gains tax and NIIT.
That sequence prevents the two mistakes I see most often: assuming every California gain is taxed at 13.3%, or assuming a 15% federal long-term rate is the whole tax bill.
