How California taxes your crypto gains
CoinLedger serves California entirely remotely, one dedicated crypto tax expert from the first import to filed forms.
California has the highest state income tax in the country. Crypto gains are ordinary income across ten brackets, from 1% to 13.3% for tax year 2026, with no long-term discount. A gain taxed at 20% federally can owe another 13.3% to Sacramento.
The Franchise Tax Board is also one of the most aggressive state tax agencies. It receives your federal information, audits people who leave the state, and looks back four years on most returns. Messy cost basis has real consequences here.
| Taxable income over | Rate |
|---|---|
| $0 | 1% |
| $11,079 | 2% |
| $26,264 | 4% |
| $41,452 | 6% |
| $57,542 | 8% |
| $72,724 | 9.3% |
| $371,479 | 10.3% |
| $445,771 | 11.3% |
| $742,953 | 12.3% |
| $1,000,000 | 13.3% |
The top 13.3% rate includes California’s 1% mental health services tax on taxable income over $1 million.

California-specific considerations
Community property
California is a community-property state. Crypto acquired during marriage generally splits between spouses, which matters for separate returns and for divorces involving crypto.
Leaving California
California taxes gains realized while you were a resident, and the FTB audits departures aggressively. A well-documented domicile change decides which state taxes the gain.
Investors who thought it was hopeless
These are real people who handed our crypto CPAs a mess and got back a finished return.
Done For You Made My Crypto Taxes Easy.
Starting the process was easy and my assigned representative was highly knowledgeable and completed my case quickly so I was able to get the information to my tax preparer well before the tax filing deadline. Based on new IRS guidance I would never have been able to prepare the crypto portion of my return without the work done by Coinledger. This was a great experience.
Outstanding Support From the CoinLedger Team
I had multiple wallets and exchanges like Coinbase, Phantom, Exodus, and Tangem. Logan and Salvatore from the CoinLedger team were extremely helpful throughout the process... They were patient, answered all of my questions, and walked me through the process step by step. Overall, the support from Logan and Salvatore made a stressful process much easier.
CoinLedger Solved My 9 Year Crypto Tax Nightmare
Jamie and the team at CoinLedger were absolute lifesavers. I had nearly nine years of crypto transactions with missing cost basis that surfaced once I started to sell... Jamie guided me on what they needed, reconciled everything quickly, and delivered the IRS forms my CPA required. What felt like an absolute nightmare became completely manageable. I can't recommend them enough!
Highly recommend the Done-For-You program
I was very pleased with the Done For You program offered by CoinLedger. The onboarding process was quick and thorough. My contact person did a great job steering me through how to get the information needed despite my lack of technical knowledge. He was able to collect and reconcile five years of data, including Celsius bankruptcy losses, and give me US-compliant tax forms for multiple accounts.
Impressive follow-through on a genuinely complex case
I hired CoinLedger's Done For You service to reconcile several years of crypto activity across multiple exchanges and wallets, a case complicated by staking income and a high volume of transactions. When the initial report showed higher gains than I expected, they dug back in, found a handful of transactions misclassified by a software bug, corrected it, and my total capital gains came down by roughly a third. Upfront, accurate, and willing to get it right.
Professional and friendly service
Jamie did an excellent job putting my crypto data in order. I had years of disorganized data from exchange closures and transfers across wallets. Jamie was able to find the missing cost basis for my crypto and prepared accurate IRS forms for filing. I would recommend this service to anyone who needs a once-and-for-all clean up of their crypto tax data.
