What Defitax is

Defitax prepares cryptocurrency transaction data for tax reporting. It calculates cost basis and gains or losses, then generates tax documents for supported jurisdictions. The web app supports Bitcoin, Solana, Ethereum, TRON, Base, BNB Chain, Polygon, and Arbitrum, with imports from listed exchanges and generic CSV. Its tracking covers DeFi and trading activity such as liquidity pool yields, prediction markets, perpetual positions, bridges, and NFTs. Users can choose FIFO, LIFO, HIFO, or Specific ID cost basis methods and track universally or by wallet. The Unlimited plan costs $199 USD per year and includes report exports, pre-filled tax forms for the United States, United Kingdom, Germany, and Australia, CSV export for other jurisdictions, and an AI Tax Agent. The free plan supports up to 500 transactions and a PnL preview, but does not export reports. Defitax uses Solana wallet authentication and says it does not collect email, name, or phone number. It warns that transaction parsing and price lookups may be inaccurate, and users are responsible for reviewing reports and filings.
