Summ
Accurate crypto taxes. No guesswork.

Summ (formerly Crypto Tax Calculator) is a cryptocurrency tax software that helps users import transactions from 3,500+ exchanges, wallets, and blockchains to automatically categorize trades and calculate tax liability. It supports DeFi, NFTs, and a wide range of chains including Ethereum, Solana, and Arbitrum. Users can generate audit-ready tax reports for themselves or share them directly with their accountant.
Users connect their exchange accounts and wallets, Summ imports and auto-categorizes all transactions with historical pricing, and then generates downloadable tax reports.
