This section requires Reporting Crypto‑Asset Service Providers carrying out Relevant Transactions who meet residency, incorporation, place‑of‑management, regular place of business or branch criteria to register with the Revenue Commissioners by 31 December in the year they first qualify and to file an annual return by the specified return date (31 May) for the calendar year. Returns must include provider identity, Reportable Users and Reportable Controlling Persons details, and aggregated transaction data by crypto‑asset and transaction type with fiat‑valuation and currency reporting rules. Due diligence follows Section III of the CARF; providers may elect to rely on equivalent Partner Jurisdiction reporting where notified to Revenue.

Providers must obtain required information from Crypto‑Asset Users and, after two written reminders and 60 days, may block Relevant Transactions. Records and due‑diligence documentation must be retained (six years generally; five years where a company is wound up or dissolved). Authorised officers may make enquiries, inspect premises and, with a District Court warrant, enter private dwellings. Penalties specified include €3,000 for record‑retention breaches, €1,265 for non‑compliance with authorised officers and €4,000 for failure to register or to make required returns. The section applies to reporting periods commencing on or after 1 January 2026 and does not apply where the information is included in a return under section 891M; anti‑avoidance provisions apply.
