What RCASPs Must Report Under CARF and How Local Rules Change the Filing

FinTax has published a detailed breakdown of what crypto platforms must actually report under the Crypto-Asset Reporting Framework, or CARF, after the questions of who reports and where they report have already been settled. Under the OECD standard, a Reporting Crypto-Asset Service Provider (RCASP) must identify reportable users and relevant controlling persons through due diligence, classify their crypto transactions, and submit three main categories of information: RCASP data, user data, and transaction data. The article says the OECD framework sets a common international baseline, but final filing obligations are shaped by local law and technical guidance in each jurisdiction. That creates practical differences in several areas, including whether domestic tax residents must be reported, which fiat currency must be used for valuation, whether the $50,000 retail payment threshold is converted into a local-currency standard, how tax identification numbers are defined, and whether nil returns are required when no reportable information exists. FinTax also argues that CARF preparation cannot be left to the filing deadline. For RCASPs, compliance work needs to be built into customer management, KYC and tax due diligence, valuation methods, and transaction data architecture. For firms operating across borders, the same customer and transaction set may need to be configured differently for different jurisdictions when annual CARF reports are prepared.
