As of 25 July 2025, 55 jurisdictions have signed the Addendum to the CRS MCAA.
Argentina signed the Addendum to the Multilateral Competent Authority Agreement on Automatic Exchange of Financial Account Information (CRS MCAA) on 1 July 2025.
This update from the OECD establishes a revised legal framework, enabling participating jurisdictions to exchange a broader range of information under the Common Reporting Standard (CRS).
The Addendum to the CRS MCAA introduces new data points for exchange under the agreement, reflecting the enhanced reporting requirements outlined in the 2023 update to the Common Reporting Standard.
The Common Reporting Standard (CRS) was developed in response to the G20 request and approved by the OECD Council on 15 July 2014. Based on a comprehensive review of the CRS, a number of amendments were adopted in 2023.
The CRS calls on jurisdictions to obtain information from their financial institutions and automatically exchange that information with other jurisdictions on an annual basis. It sets out the financial account information to be exchanged, the financial institutions required to report, the different types of accounts and taxpayers covered, as well as common due diligence procedures to be followed by financial institutions.
The CRS was designed with a broad scope in terms of the financial information to be reported, the Account Holders subject to reporting, and the Financial Institutions required to report, in order to limit the opportunities for taxpayers to circumvent reporting. It also requires that jurisdictions, as part of their effective implementation of the CRS, put in place anti-abuse rules to prevent any practices intended to circumvent the reporting and due diligence procedures.
As of 25 July 2025, 55 jurisdictions have signed the Addendum to the CRS MCAA.
