Coinbase Expands Tax Tools with CoinTracker Integration to Simplify Crypto Tax Filing

Odaily News Coinbase announced the expansion of its tax tools ahead of the 2026 tax filing season, integrating with tax partner CoinTracker to help users automatically fill in missing cost basis information, simplifying the reporting of gains from digital asset transactions. The new Form 1099-DA will report the total proceeds from digital asset sales or exchanges, but transactions on decentralized exchanges (DEX) are not included in the form and require users to self-report. Coinbase will provide cost basis information; if assets originate from external wallets or exchanges, they will be marked as "unknown," at which point the CoinTracker tool can automatically match and supplement the missing data.
