California Capital Gains Tax Rate 2026: 13.3% Top Rate
California does not distinguish between long-term and short-term capital gains — both are taxed as ordinary income at the state's progressive brackets, topping out at 13.3% for taxable income above $1 million (plus the 1% mental health surtax). Per the California Franchise Tax Board (FTB), this is the highest state rate in the nation for capital gains — no preferential treatment for held assets. This state tax stacks on top of the federal capital gains rate you owe to the IRS.
Federal vs California Capital Gains Tax
The federal capital gains tax rate depends on your income and how long you held the asset. For long-term gains (held over 12 months), the 2026 federal rates per IRS Topic 409 are 0% (income up to $48,350 single / $96,700 MFJ), 15% (up to $533,400 single / $600,050 MFJ), and 20% above those thresholds. Short-term gains are taxed as ordinary income at your marginal federal rate.
California's 13.3% state rate is applied on top of the federal rate. For example, a California resident in the 15% federal bracket who realizes a long-term gain would owe 15% federal + 13.3% state = a combined rate of 28.3%. Add the 3.8% Net Investment Income Tax (NIIT) for high earners and the top combined burden reaches 37.1%. This stacking effect makes state-level planning essential for high-gain transactions.
Worked Example: California Capital Gains Tax on a $500,000 Home Sale in 2026
Suppose a single filer bought a Los Angeles condo for $400,000 in 2019 and sells for $900,000 in July 2026 — a $500,000 gain over 87 months holding. First, the federal Section 121 primary-residence exclusion removes the first $250,000 (single filer), leaving a $250,000 taxable gain. Assuming $150,000 taxable income, the federal long-term rate is 15% = $37,500 federal tax. California FTB taxes the full $250,000 gain as ordinary income at roughly 9.3% (the effective bracket at this income) = $23,250 state tax. Total tax: $60,750 combined. Net after-tax proceeds from the $900,000 sale (assuming $400,000 basis + $60,750 tax) = $439,250 net cash. Married filers jointly claiming the $500,000 exclusion would owe $0 on the same sale.
California Cap Gains Strategies & Exemptions
Several strategies can help California taxpayers reduce their capital gains tax burden. First, hold assets for more than 12 months to qualify for the lower long-term federal rate. Second, harvest capital losses to offset gains — if you have losing positions, selling them in the same tax year can reduce your net taxable gain. Third, use tax-advantaged accounts (401k, IRA, HSA) to shelter future investment growth from both federal and California state tax.
For California homeowners, the federal home-sale exclusion allows you to exclude up to $250,000 (single) or $500,000 (married filing jointly) of gain from the sale of a primary residence, provided you meet the 2-of-5-year ownership and use tests. Note: California conforms to the federal Section 121 exclusion — the same $250K/$500K limits apply at the state level. Consult a California tax professional before executing large asset sales.
Advanced strategies include 1031 exchanges for investment real estate (defers state and federal tax when swapping like-kind property), Opportunity Zone reinvestment (federal deferral until 2026 recognition; California does not conform to the federal OZ program per FTB Notice 2019-05), and installment sales that spread the gain across multiple tax years. Each has strict rules — always work with a qualified California CPA before executing.
California vs No-Tax States for Capital Gains Planning
Nine states charge $0 state capital gains tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. For a Californian planning to sell a heavily-appreciated business, stock position, or crypto holding, establishing genuine residency in one of these states BEFORE the sale can save the full 13.3%. On a $2 million gain, that is $266,000 saved — enough to justify the move for many high-net-worth sellers. The catch: California aggressively audits mid-year moves under the FTB's residency rules (FTB Publication 1031). To break residency you generally must sell the CA home, register vehicles in the new state, move family and personal belongings, obtain a new driver's license, and stay out of California more than half the year in the sale year. Washington added a 7% capital gains tax on gains above $270,000 in 2022 (still far below CA's 13.3%). Compare our Washington capital gains calculator for the state-move math.

Frequently Asked Questions
What is the California capital gains tax rate in 2026?
The California capital gains tax rate in 2026 is up to 13.3% at the top marginal bracket (income above $1M). California does not offer preferential long-term rates — all capital gains are taxed as ordinary income at the state's progressive brackets, per the California Franchise Tax Board.
Does California tax short-term vs long-term capital gains differently?
No — California treats all capital gains as ordinary income regardless of holding period. There is no separate short-term/long-term rate at the state level. Only the federal government distinguishes them (0/15/20% long-term vs your marginal rate for short-term).
Are there California capital gains exemptions?
The main exemption is the federal Section 121 primary-residence exclusion, which California fully conforms to — $250,000 gain excluded for single filers, $500,000 for married filing jointly, if you owned and used the home 2 of the last 5 years. California does NOT conform to the federal Opportunity Zone program, so OZ deferral only helps federally.
How does California capital gains compare to federal rates?
Federal capital gains tax rates (0%, 15%, 20%) are set by the IRS per Topic 409 and apply in addition to California state tax. Long-term gains (assets held over 12 months) receive lower federal rates. California's state rate of up to 13.3% stacks on top, so a high earner's combined burden can reach 37.1% including the 3.8% NIIT.
Do I owe California capital gains tax if I move before selling?
If you move before selling an asset, your state tax obligation depends on residency at the time of sale. California aggressively audits mid-year moves — you must genuinely break residency (sell CA home, register vehicles elsewhere, spend >183 days out of state, obtain new driver's license) per FTB Publication 1031. Otherwise the FTB will treat the gain as California-source income.
Does the Net Investment Income Tax (NIIT) apply on top of California capital gains?
Yes. The federal 3.8% Net Investment Income Tax under IRC Section 1411 applies to single filers with MAGI above $200,000 (or $250,000 for MFJ). So a high-earning California resident selling stock could face 20% federal LTCG + 3.8% NIIT + 13.3% California = 37.1% combined marginal rate. This calculator estimates federal LTCG + California only; add 3.8% NIIT if you exceed the threshold.
How does the primary residence exclusion work for a California home sale?
Under IRS Section 121, a single filer excludes up to $250,000 of gain and a joint filer up to $500,000 on the sale of a primary residence, provided you owned AND used it as your primary home for at least 2 of the last 5 years. California conforms fully. Example: a joint filer with a $450,000 gain on a Los Angeles condo owes $0 in federal or California capital gains tax. Only the gain exceeding the exclusion is taxable.
