CRYPTO TAXES: WHAT EVERY HOLDER MUST KNOW
Plain English
The IRS treats crypto as property, not currency. That means every time you sell, swap, or spend crypto, it's a taxable event — even trading one token for another. Miss this and you could owe taxes you weren't expecting. The record-keeping requirements in crypto are far more demanding than stocks.
Going deeper
IRS crypto tax rules (US): (1) Every disposal is taxable — selling crypto for USD, trading crypto-to-crypto, or using crypto to buy goods/services all trigger a capital gains event. (2) Short-term vs. long-term: held < 1 year = taxed as ordinary income (up to 37%). Held > 1 year = taxed at long-term capital gains rates (0%, 15%, or 20%). (3) Cost basis methods: FIFO (first in, first out — default), LIFO, HIFO (highest cost first — often minimizes taxes), Specific ID. HIFO sells your most expensive tokens first, reducing realized gains. (4) Staking rewards: taxed as ordinary income when received, at fair market value. (5) DeFi complexity: each swap on Uniswap is a taxable event. Token-to-token swaps are sales + purchases. (6) Airdrops and forks: taxed as ordinary income at fair market value when received. (7) Lost or stolen crypto: may be deductible as a capital loss (consult a tax professional). Key tools: Koinly, CoinTracker, TaxBit, CryptoTaxCalculator — they import transaction history from exchanges and wallets automatically. Cost basis tracking across years of DeFi activity is one of crypto's biggest practical challenges.
Examples
The Hidden Swap Tax
You buy ETH for $3,000. ETH rises to $5,000. You swap ETH for SOL on Uniswap. The IRS treats this as: sell ETH at $5,000 (triggering a $2,000 capital gain) and buy SOL. You owe taxes on $2,000 even though you never touched USD. Many new crypto users don't realize swaps are taxable — they get a surprise tax bill.
HIFO Method Advantage
You bought 1 BTC at $10k, 1 BTC at $30k, 1 BTC at $60k. BTC is now at $70k and you sell 1 BTC. FIFO: you sell the $10k coin → $60k gain. HIFO: you sell the $60k coin → $10k gain. Same sale, but HIFO reduces your taxable gain by $50,000. Over a lifetime of trading, cost basis method selection can save tens of thousands in taxes.
