What it is

Defitax is a web tool for preparing cryptocurrency transaction data for tax reporting. It calculates cost basis and gains or losses, then produces tax documents. The service is aimed at DeFi traders using liquidity pools, bonding curves, prediction markets, perpetual futures and related activities. It lists support for Bitcoin, Solana, Ethereum, TRON, Base, BNB Chain, Polygon and Arbitrum, with imports from Binance, Coinbase, Kraken, Bybit, OKX, Hyperliquid, MEXC, Orderly, CoinSpot and generic CSV files. Tracking covers Hyperliquid perpetuals, prediction markets, launch platforms, liquidity-pool yields, Jupiter DCA and perpetual positions, bridges and NFTs. Cost-basis choices are FIFO, LIFO, HIFO and Specific ID, applied universally or per wallet. The free plan allows up to 500 transactions and provides a dashboard but no report export. Unlimited costs $199 a year and adds exports, tax forms, multi-jurisdiction support and the AI Tax Agent.
