Crypto Tax Calculator

Calculate crypto capital gains and losses using FIFO cost-basis accounting from a CSV of buy/sell transactions across BTC, ETH, SOL, and any other tracked asset. Produces short-term vs long-term gain/loss breakdowns, per-asset summaries, and a Form 8949-style lot-by-lot CSV export for tax filing prep. Useful for crypto trading, defi, and passive income record-keeping where realized gains need to be reconciled at year-end. Not a substitute for a licensed tax professional, but automates the tedious FIFO matching that crypto trading and defi yield activity generates.
