California Capital Gains Tax 2026
Estimate the state tax attributable to a gain, then separate it from the federal capital-gains calculation.
State-specific rule
Federal exclusions and basis rules can affect the amount entering California taxable income, but the state rate applied to a taxable gain depends on the taxpayer’s other income.
Calculate the California state layer
Enter other state taxable income so the calculator can measure the incremental tax created by the gain.
State tax on gain
$9,300State tax before gain
$5,842State tax after gain
$15,142Models the gain as additional state taxable income using the selected year’s state brackets. State-specific exclusions, credits and local taxes are not included.
Frequently asked questions
Does California have a lower rate for long-term capital gains?
California generally taxes capital gains as ordinary income under its progressive personal-income-tax brackets; it does not provide a lower general rate for long-term gains.
Does this include federal capital gains tax?
No. This page estimates the state layer. Use the federal capital gains calculator for the 0%, 15% or 20% long-term rate, ordinary short-term rates and possible 3.8% NIIT.
Why does other income change the result?
The gain can stack on top of other taxable income. In a progressive system, some or all of the gain may therefore fall into higher state brackets.
