Budget-friendly crypto tax software (formerly BearTax) for straightforward filing
Last updated: July 2026
Fyn (formerly BearTax) is a long-running, budget-friendly crypto tax platform aimed at investors who want straightforward, affordable tax reporting without premium pricing. It imports from major exchanges and wallets, computes gains and losses, handles common crypto activity, and generates tax forms for the US and several other countries, with a smart-matching feature to pair buys and sells. Its long history and low prices have made it a practical choice for investors with relatively standard trading activity who don't need the deepest DeFi tooling. It offers tiered plans by transaction volume at competitive price points. The trade-offs: as a value-focused veteran, its DeFi, NFT, and complex on-chain support trails the newer specialists (it's best for exchange-and-wallet trading rather than heavy DeFi degen activity); its interface and feature set are more utilitarian than the sleekest modern tools; and support depth reflects its budget positioning. But for investors with fairly standard crypto trading who want a proven, inexpensive tool to generate their tax reports — without paying for advanced DeFi features they don't need — Fyn is a cost-effective and established option.
