DAC8

DAC8 governs reporting, not tax liability itself: it gives tax authorities visibility into crypto-asset transactions, while calculating and declaring what's actually owed remains the individual taxpayer's responsibility under each member state's domestic tax rules. Formally Council Directive (EU) 2023/2226, DAC8 amends Directive 2011/16/EU, the EU's core framework for administrative cooperation in tax matters, to incorporate the OECD's CARF alongside the OECD's parallel amendments to the Common Reporting Standard (CRS).

It requires Reporting Crypto-Asset Service Providers (RCASPs), regardless of where they are established, to report on EU-resident users' crypto-asset transactions. It also updates the EU's existing DAC2/CRS rules to bring in Central Bank Digital Currencies (CBDCs) and specified e-money products, an approach often referred to as "CRS 2.0."

Certain users are carved out as "Excluded Persons": listed entities and their related entities, government bodies, international organizations, central banks, and financial institutions other than certain investment entities. Transactions with them are not reportable. 

Crypto-Asset Operators must register with one member state, determined by their nexus or branch. Non-EU operators are relieved of reporting only where their jurisdiction has an effective information-exchange agreement with the member states concerned. 

Data is exchanged in a standardized XML format based on the OECD's CARF and CRS schemas with EU extensions. 

The core obligations of a Reporting Crypto-Asset Service Provider include:

• Collecting self-certifications confirming each user's name, address, tax residence, TIN, date of birth and, for entities, their controlling persons 
• Monitoring for changes in circumstances affecting a user's reportable status
• Reporting annually to their home member state's tax authority on both the user and their transactions

DAC8 is one of several reporting regimes now operating in parallel. CARF, CRS 2.0, and the US Form 1099-DA each have distinct scopes, data schemas, and implementation timelines. High-frequency, wallet-based activity generates large volumes of structured and unstructured data that must be reconciled and reported accurately at scale.

Lessons from the Foreign Account Tax Compliance Act (FATCA) and CRS show that most compliance failures stem not from complex rules but from operational gaps and poor data quality. Scalable, cloud-native infrastructure, with automated classification, defensible audit trails, and adaptable workflows, is what lets firms absorb new jurisdictions and schema changes without rebuilding each time.
