DAC8: crypto-asset service providers report from 2026
Council Directive (EU) 2023/2226 of 17 October 2023 has every member state require crypto-asset service providers to report their users' transactions, and the member states exchange what they collect. They apply it from 1 January 2026, so 2026 is the first reported year: this is about what a tax authority already holds, not a new tax.
