Every taxable crypto disposal (sell, swap, spend) is one row. Each row needs: description (e.g. "0.5 BTC"), date acquired, date sold, proceeds, cost basis, gain or loss. Short-term and long-term are reported in separate sections of the form (Part I and Part II).
What this tool does
It runs FIFO lot matching across your transactions and outputs the exact rows. Copy them into your filing software or attach the CSV. Not tax advice — confirm with a CPA, especially if you have airdrops, staking rewards, NFTs, DeFi swaps, or wallet-to-wallet transfers (those need extra handling not yet supported here).
