Defitax
What it is
Defitax prepares cryptocurrency transaction data for tax reporting by calculating cost basis and gains or losses, then generating tax documents. The web tool is aimed at DeFi traders, including those using liquidity pools, bonding curves, prediction markets, and perpetual futures. Listed supported chains include Bitcoin, Solana, Ethereum, TRON, Base, BNB Chain, Polygon, and Arbitrum; imports include Binance, Coinbase, Kraken, Bybit, OKX, Hyperliquid, MEXC, Orderly, CoinSpot, and generic CSV.
The product describes automatic tracking for Hyperliquid perpetuals, prediction markets, launch platforms, liquidity pool yields, Jupiter DCA and perpetual positions, bridges, and NFTs. Cost basis options are FIFO, LIFO, HIFO, and Specific ID, with universal or per-wallet tracking. Unlimited includes pre-filled IRS Form 8949 and Schedule D, UK SA108, German Anlage SO, Australian CGT forms, CSV exports for other jurisdictions, and an AI Tax Agent for questions about transaction data, PnL, cost basis, and classifications. The Free plan allows up to 500 transactions but has no report export. Unlimited costs $199 a year, paid once with USDC on Solana. Defitax warns that transaction parsing, classification, and price lookups may be inaccurate; users are responsible for reviewing reports and filings.
