What CARF means for you
The OECD’s Crypto-Asset Reporting Framework (CARF) took effect on 1 January 2026 in the first group of committed jurisdictions. That includes the UK, Ireland and the rest of the EU through DAC8, the Cayman Islands, Japan and Korea. If you run an exchange, brokerage, custodial wallet or similar crypto service, you are now a Reporting Crypto-Asset Service Provider (RCASP).
That means collecting tax residence and TIN details from every user, tracking their crypto-to-fiat, crypto-to-crypto and transfer activity, and filing an annual return in your tax authority’s XML schema. The first returns, covering 2026, fall due from 31 May 2027. Tax authorities begin exchanging the data with each other by 30 September 2027.
DataTracks Oxbow does the heavy lifting. Connect your user and transaction data, and the platform populates the data, validates it, structures it and generates the CARF XML for each jurisdiction you report in.
