The Growing Challenge of DAC8 & CARF Compliance
The EU's DAC8 directive and global CARF framework require crypto-asset service providers to report transaction information to tax authorities. Non-compliance can result in penalties ranging from EUR 20,000 to EUR 500,000 and operational disruptions.
Manual Data Collection
Manual collection of crypto transaction data, wallet addresses, and tax residency information is error-prone, leading to rejected filings and fines up to EUR 500,000.
Fragmented Sources
Crypto transaction data is scattered across blockchain networks, exchanges, and wallets, making manual collection extremely complex.
Heavy Penalties
Authorities impose fines from EUR 20,000 to EUR 500,000 for non-compliance, with additional requirements to block non-compliant users..
Cross-Border Complexity
Navigating reporting requirements across 58+ CARF-implementing jurisdictions including EU, UK, Australia, Canada, and Singapore is complex.
