Crypto Tax Guide for US Investors 2026: Every Rule Explained
The IRS treats crypto as property. Every trade, swap, and DeFi interaction may be taxable. This guide covers every US crypto tax rule, minimization strategies, and reporting requirements.
The IRS has treated cryptocurrency as property since 2014. This means every disposal (sale, trade, exchange, spending) is potentially a taxable event. In 2026, with expanded 1099-DA reporting requirements, the IRS has unprecedented visibility into crypto activity.
What Is a Taxable Event
- Selling crypto for USD/fiat: capital gains/loss (long or short term)
- Trading one crypto for another: taxable at fair market value of received asset
- Using crypto to buy goods or services: capital gains on the crypto used
- Receiving staking rewards, mining income, airdrops: ordinary income at receipt
What Is NOT a Taxable Event
- Buying crypto with fiat (buying is not taxable — only selling)
- Transferring between your own wallets
- Holding crypto (unrealized gains are not taxed until realized)
- Wrapping tokens (e.g., ETH→WETH) — treated as same asset per most interpretations
Tax-Loss Harvesting in Crypto
Unlike stocks, crypto is not subject to the wash-sale rule (as of 2026). You can sell Bitcoin at a loss, immediately buy it back, and claim the loss for tax purposes. This "tax-loss harvesting" can offset gains from other crypto sales, reducing your tax bill. Platforms like Koinly and CoinTracker automate loss harvesting recommendations.
DeFi-Specific Tax Issues
- LP entry: adding tokens to a pool may be a taxable exchange
- LP exit: taxable at fair market value of received tokens
- Yield farming: each reward token receipt is income at FMV
- Gas fees: can be deducted as a cost basis addition to the transaction
