DAC8 (Directive on Administrative Cooperation 8)
Web3 / regulatory frameworks
DAC8, the eighth amendment to the EU's Directive on Administrative Cooperation, incorporates the OECD's Crypto-Asset Reporting Framework into European law and extends existing automatic information exchange mechanisms to cryptocurrency transactions. This directive mandates that EU member states require crypto-asset service providers—including exchanges, custodians, and wallet providers—to report comprehensive customer transaction data to national tax authorities, which then exchange this information with other member states automatically. DAC8 represents a critical step in harmonizing crypto tax transparency across Europe and aligning EU practices with international CARF standards. Example: Under DAC8, a Portuguese cryptocurrency exchange must report detailed transaction information about its German customers to Portuguese tax authorities, which then automatically forward that data to German tax authorities for verification against domestic tax returns. Why it matters for crypto regulation: DAC8 creates a unified European tax reporting system for crypto assets. It prevents regulatory arbitrage where individuals exploit weaker reporting requirements in certain jurisdictions, ensuring equitable tax enforcement and significantly raising compliance standards across all member states.
