How EU and UK crypto platforms are already building your 2027 tax report
EU DAC8 and the UK Cryptoasset Reporting Framework (CARF) began applying on Jan. 1, 2026. Crypto providers now collect user identity and transaction data during 2026, then file annual reports in 2027; some reports are exchanged onward to the user’s country of tax residence. Reporting depends on provider location, user tax residence, and the relevant list/relationship rules. EU providers report to their home authority, which exchanges data for resident users within the bloc. UK providers report to HMRC, which may share data only with jurisdictions that have an active agreement and appear on the UK reportable-jurisdiction list. The reports are standardized summaries, not full transaction histories. They include annual aggregate values, units, and categorized cryptoasset activity, but not cost basis, gains, or tax due. Users still need detailed records across exchanges and wallets to calculate liabilities.
