How the IRS Treats Cryptocurrency

The IRS treats cryptocurrency as property, not currency. This means every transaction involving cryptocurrency — buying, selling, exchanging, or using it to purchase goods or services — is a taxable event that must be reported on your tax return. The IRS requires every taxpayer to answer a yes/no question about cryptocurrency transactions on the front page of Form 1040. Answering "no" when you had crypto transactions is a false statement on a federal tax return.

What Is a Taxable Event?

The following are taxable events for cryptocurrency: (1) Selling cryptocurrency for cash. (2) Exchanging one cryptocurrency for another (e.g., trading Bitcoin for Ethereum). (3) Using cryptocurrency to purchase goods or services. (4) Receiving cryptocurrency as payment for services (ordinary income). (5) Mining cryptocurrency (ordinary income at fair market value when received). (6) Receiving staking rewards (ordinary income). The following are NOT taxable events: buying cryptocurrency with cash, transferring cryptocurrency between your own wallets, and holding cryptocurrency.

California Crypto Tax Rules

California taxes cryptocurrency gains as ordinary income — there is no preferential capital gains rate in California. A California taxpayer who sells Bitcoin at a long-term gain pays 20% federal (plus 3.8% NIIT if applicable) plus up to 13.3% California — a combined rate of up to 37.1%. California also does not recognize any special treatment for cryptocurrency received as compensation — it is taxed as ordinary income at the time of receipt.

Reporting Requirements

Cryptocurrency gains and losses are reported on Form 8949 and Schedule D. Each transaction must be reported separately with the date acquired, date sold, proceeds, cost basis, and gain or loss. For taxpayers with hundreds or thousands of transactions, KDA uses specialized crypto tax software to import transaction data from exchanges and calculate the correct cost basis using the specific identification or FIFO method.

DeFi, NFTs & Staking

Decentralized finance (DeFi) transactions are among the most complex areas of crypto taxation. Providing liquidity to a DeFi protocol may be treated as a taxable exchange. Receiving liquidity provider tokens may be taxable income. NFT sales are taxable events — gains are reported on Form 8949. NFTs held as collectibles may be subject to a 28% federal rate rather than the standard 20% long-term rate. Staking rewards are ordinary income at fair market value when received. KDA stays current on IRS guidance for DeFi and NFT transactions.

Tax Planning for Crypto

KDA's crypto tax planning strategies: (1) Hold for long-term — holding assets more than one year qualifies for the lower federal long-term rate (though California taxes all gains as ordinary income). (2) Tax-loss harvesting — cryptocurrency is not subject to wash-sale rules (unlike stocks), so you can sell at a loss and immediately repurchase. (3) Charitable giving — donating appreciated crypto to charity avoids capital gains and generates a charitable deduction. (4) Timing — defer sales to years with lower income to stay in lower tax brackets.

Frequently Asked Questions

Common Questions About Crypto Tax California

Do I have to report crypto transactions if I only traded on a foreign exchange?
Yes. U.S. taxpayers must report all cryptocurrency transactions regardless of where the exchange is located. The IRS receives data from U.S. exchanges and is increasingly obtaining data from foreign exchanges through international information sharing agreements.
If you received cryptocurrency as a gift, your cost basis is the donor's original cost basis (for calculating gain) or the fair market value on the date of the gift (for calculating loss), whichever is lower. You also need to know the donor's holding period to determine whether your gain is short-term or long-term.
Yes. Cryptocurrency losses are deductible as capital losses. Capital losses first offset capital gains; excess losses can offset up to $3,000 of ordinary income per year, with the remainder carried forward indefinitely. Unlike stocks, crypto is not subject to wash-sale rules, so you can sell at a loss and immediately repurchase.
