Key Facts

Key Facts About Crypto Taxes in California

  • California taxes crypto gains as ordinary income at rates up to 13.3%, the highest in the U.S.
  • California conforms to federal crypto tax treatment (cost basis, FIFO/specific-ID, capital gains classification).
  • California does not offer preferential long-term capital gains rates at the state level.
  • The Franchise Tax Board (FTB) actively audits crypto-related residency claims for high earners exiting California.
  • Federal crypto tax preparation by a CPA licensed in any state is legally valid for California residents.

California crypto investors face a unique double-stack: federal capital gains tax PLUS the highest state income tax in the country at 13.3%. We help residents from Los Angeles to San Diego to the Bay Area properly reconcile their portfolios, claim every legitimate basis adjustment, and plan for exit scenarios when relocating to lower-tax states like Nevada or Texas. Garrett's California CPA license (#133092) means he understands FTB nuances first-hand, but because federal tax law is uniform, his federal return preparation works for residents anywhere.

Common Issues

Common Crypto Tax Issues in California

Missing or incomplete cost basis

Exchanges lose data, wallets get abandoned, and chain history gets fragmented. Reconstructing accurate cost basis across years of trading is the #1 challenge we solve.

DeFi and cross-chain complexity

Liquidity pool entries, yield farming, cross-chain bridges, wrapped tokens, and restaking events each create taxable moments that most software misses or misclassifies.

Unreported prior-year activity

Many crypto investors discover years of unreported trades after receiving an IRS letter. We help with back-year reconstruction, voluntary disclosure, and getting compliant without panic.

Exit-planning before relocating to a no-income-tax state (FTB residency audits)

AB-150 PTET interplay for crypto trading entities
