Coinbase expands tax tools and integrates CoinTracker to simplify cryptocurrency tax reporting Odaily Planet Daily News: Coinbase announced the expansion of its tax tools before the 2026 tax season, integrating with tax partner CoinTracker to help users automatically fill in missing cost bases and simplify the reporting of digital asset trading profits. The new Form 1099-DA will report the total revenue from the sale or exchange of digital assets, but decentralized exchange (DEX) transactions are not included in the form and users need to declare them themselves. Coinbase will provide cost based information, and if the asset comes from an external wallet or exchange, it will be displayed as "unknown". At this time, the CoinTracker tool can automatically match and supplement missing data.
