The Swiss Official Gazette published Decision No. RO 2025 243 on 11 April 2025 which updates the list of countries participating in the Multilateral Competent Authority Agreement (MCAA) for the exchange of country-by-country reports (CbCR).

The updated list now includes:

  • Antigua and Barbuda, effective from 1 January 2025;
  • Serbia , effective from 1 January 2024.

The decision came into effect on 1 April 2025.

The MCAA is a multilateral framework agreement that provides a standardised and efficient mechanism to facilitate the automatic exchange of information. It avoids the need for several bilateral agreements to be concluded. Its design as a framework agreement means the MCAA always ensures each signatory has ultimate control over exactly which exchange relationships it enters into and that each signatory’s standards on confidentiality, data protection and appropriate use of information always apply.

Country-by-Country Reporting (CbCR), with the specific document for an entity known as a Country-by-Country report or CbC report, is an international initiative led by the OECD. It sets a reporting standard for multinational enterprises (MNEs) with total consolidated group revenues exceeding EUR 750 million.
