Mauritius has joined the OECD’s global crypto-asset transparency initiative by signing the CARF MCAA, as jurisdictions continue to expand automatic information exchange frameworks to address emerging crypto risks and strengthen cross-border tax compliance.
The OECD announced, on 12 December 2025, that Mauritius signed the Multilateral Competent Authority Agreement on Automatic Exchange of Information under the Crypto-Asset Reporting Framework (CARF MCAA).
The CARF MCAA establishes a framework for the automatic exchange of information on crypto-assets, in line with the OECD’s reporting and due diligence standards. Its goal is to help tax authorities address risks linked to the fast-growing crypto market and maintain transparency across borders.
The CRS MCAA Addendum expands the scope of information to be exchanged under the CRS MCAA, incorporating additional reporting obligations introduced by the 2023 revision of the Common Reporting Standard. These enhancements are intended to maintain the CRS’s effectiveness in tackling international tax compliance issues.
As of 12 December 2025, 55 jurisdictions have signed the Addendum to the CRS.
