California tax on stocks and ETFs

California generally taxes stocks and ETFs gains under its graduated income-tax framework (Graduated income tax (top rate up to 13.3%)). This estimate applies the top modeled California rate to remaining taxable gain.

Federal rules for stocks and ETFs: Broker sales generally report on Form 1099-B and flow to Form 8949 and Schedule D. Wash-sale disallowance can apply if you repurchase a substantially identical security within 30 days. Holding period still matters for LTCG vs STCG except where a longer QSBS or real-estate test applies.

Open the parent California calculator for a generic sale, or the national Stocks lander for asset-only copy. Nearby states below keep the same stocks preset so you can compare residency. Estimates are not tax advice.

A stock or ETF loss can be disallowed if you buy the same or a substantially identical security inside the 30-day wash-sale window. This illustration does not turn that disallowance on.

California does not give capital gains a preferential state rate. The model applies graduated income tax with a top rate up to 13.3% to taxable gain, the same way it treats wages. A long-term federal 15% or 20% bill can therefore sit next to a larger California line on a big sale.

The Mental Health Services Tax is not added on top of that 13.3% figure in this calculator. Residency, not the exchange where the shares traded, is what this page assumes for the state line.

FAQ

California Stocks FAQs

How does California tax stocks and ETFs capital gains?

Do wash sales change a California stocks estimate?

Federally, a wash sale can disallow a securities loss. California then taxes remaining recognized gain under graduated income tax (top rate up to 13.3%). Mark the wash-sale checkbox if you replaced shares inside 30 days.

Which IRS forms apply to a California stocks sale?

Plan around Form 1099-B, Form 8949, and Schedule D. California may require its own income-tax return when the state line is not $0. NIIT, if any, is computed on Form 8960.

Does California tax stocks gains if I am a part-year resident?

This page assumes full-year California residency and applies graduated income tax (top rate up to 13.3%) to taxable stocks and ETFs gain. Part-year allocation and nonresident sourcing are not modeled — use California instructions or a CPA.

What does the California Stocks illustration assume?

The California Stocks rows use a single filer with $80,000 of other income and a long-term gain in 2026. A stock or ETF loss can be disallowed if you buy the same or a substantially identical security inside the 30-day wash-sale window. This illustration does not turn that disallowance on. Texas is the no-tax comparison, not a second residency.
