EU’s DAC8 Brings Crypto Under Full Tax Transparency From 2026

The European Union is set to tighten oversight of digital assets with Council Directive (EU) 2023/2226 — known as DAC8 — which takes effect on Jan. 1, 2026. While the rules do not introduce new crypto taxes, they significantly expand tax transparency by requiring crypto-asset service providers (CASPs) to collect and report user identity details, tax residency information and transaction data in a standardized format. That information will then be automatically exchanged between EU tax authorities, closing long-standing cross-border reporting gaps.

DAC8 extends the EU’s existing Directive on Administrative Cooperation framework to crypto, placing digital assets under the same transparency regime as traditional financial accounts. The move aligns closely with the Organisation for Economic Co-operation and Development’s Crypto-Asset Reporting Framework (CARF), ensuring compatibility with non-EU jurisdictions adopting similar standards. Together with Markets in Crypto-Assets Regulation (MiCA), the directive forms a dual-layer system governing both market conduct and tax reporting.
