Crypto Tax & Regulation in California: 2026 State Guide
🇺🇸 State Tax: Up to 13.3%How California Taxes Crypto
Crypto activity in the United States is taxed at both federal and state level. The federal IRS treats cryptocurrency as property — every disposal triggers capital gains tax at federal short-term (10%–37%) or long-term (0%, 15%, 20%) rates, plus the 3.8% Net Investment Income Tax for high earners.
On top of that, California applies its own state income tax. Up to 13.3% applies to ordinary income, which most states (including California) extend to crypto capital gains.
California-specific details: California's Digital Financial Assets Law (DFAL) takes effect July 2025, creating a state-level crypto licensing regime. Highest state income tax in the US.
Money Transmission & Crypto Licensing in California
California operates one of the strictest state-level crypto licensing regimes in the United States. Exchanges and crypto-asset service providers must hold a state-specific authorisation to serve California residents. This significantly reduces the number of platforms accessible to California-based users.
Combined Federal + California Tax
Your total tax on crypto gains in California combines federal and state. As an illustration:
- Short-term gains (held ≤12 months): federal ordinary income rate (up to 37%) + Up to 13.3% state tax.
- Long-term gains (held >12 months): federal preferential rate (0%, 15%, or 20%) + Up to 13.3% state tax (most states tax long-term gains at the same rate as ordinary income — there is no federal-style discount at state level for most states).
- 3.8% NIIT if your modified AGI exceeds $200,000 single / $250,000 joint.
