Mexico signed the Addendum to the Multilateral Competent Authority Agreement on Automatic Exchange of Financial Account Information (CRS MCAA) on 21 November 2025.
The addendum updates the Common Reporting Standard (CRS) with additional reporting requirements adopted in 2023, including expanded information on crypto-assets, and strengthens due diligence procedures.
The measure is intended to ensure the CRS remains effective in promoting international tax compliance. According to the OECD, 69 jurisdictions have signed the addendum as of 12 December 2025.
The Addendum to the CRS MCAA reflects ongoing global efforts to enhance transparency in cross-border financial reporting and strengthen measures against tax evasion.
