If you use a crypto platform in the European Union or the United Kingdom, some of your 2026 activity may already be being recorded and will be used to feed tax-information reports in 2027. The EUs DAC8 rules and the UKs Cryptoasset Reporting Framework, known as CARF, both began applying on Jan. 1, 2026. The reporting chain now has three distinct stages: a provider collects information during 2026, sends an annual report to the authority to which it must report, and, in some cases, that authority routes the information to the users country of tax residence. Coverage depends on the provider, the user, the activity and the relevant reporting regime. What providers collect and where it goes Under DAC8, crypto-asset service providers collect data on reportable transactions involving EU residents, including users living in the providers own Member State.
