Beyond simple buys and sells, Ethereum users hit extra taxable events: staking rewards are income at fair-market-value when received (and then capital gains on later sale), swaps on Uniswap or any DEX are taxable disposals, and airdrops and forks are income at the moment you have control. Wallet-to-wallet transfers (e.g. moving ETH from Coinbase to a Ledger) are not taxable.
The calculator below handles ETH buys and sells (FIFO matched). For staking income and DEX swap chains, talk to a CPA — or run the paid portfolio audit for a full-stack analysis.
