25/05/2026 – Latin American countries identified more than EUR 576 million in additional tax revenue in 2025 through exchange of information (EOI) and related voluntary disclosure programmes, according to a new report published today by the Global Forum on Transparency and Exchange of Information for Tax Purposes (Global Forum).
Tax Transparency in Latin America 2026: Latin America Initiative Progress Report shows how countries across the region are systematically integrating EOI deeper into compliance activities. Latin American countries have identified EUR 29 billion in additional revenue since 2009, corresponding to 21% of all additional revenue identified globally through EOI programmes, according to the report.
Latin America benefits from one of the world’s most extensive networks for international tax co‑operation, comprising over 2 000 exchange relationships, 79% of which are established through the Convention on Mutual Administrative Assistance in Tax Matters. Most Latin American countries now have fully operational EOI frameworks, including empowered competent authorities, dedicated units and robust internal procedures.
The exchange of information on request (EOIR) continues to mature across the region and its use has become more diversified: whereas four countries accounted for 95.5% of requests between 2009 and 2018, 10 countries now represent 99.9% of the requests sent, underscoring the emergence of new, increasingly active jurisdictions.
The automatic exchange information on financial accounts under the Common Reporting Standard (CRS) strongly benefits tax administrations across Latin America. Ten Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Mexico, Panama, Peru and Uruguay) have already started exchanging, as Paraguay is preparing to commence in 2027. In 2025, tax authorities in the region received information on more than 5 million foreign financial accounts, covering EUR 463 billion in assets.
Latin American countries have further strengthened the legal and practical implementation of the tax transparency standards, with Global Forum peer reviews showing steady overall improvement. More than three quarters of the jurisdictions assessed have satisfactory EOIR ratings, although some weaknesses persist in the effective supervision and enforcement of beneficial ownership requirements. CRS frameworks are largely in place from a legal perspective, but practical implementation remains uneven. Key challenges include strengthening compliance activities, ensuring effective risk‑based oversight of financial institutions, and accurately identifying the full scope of entities that fall within the CRS reporting obligations.
Six Latin American countries (Brazil, Chile, Colombia, Costa Rica, Mexico and Panama) have formally committed to implement the new Crypto‑Asset Reporting Framework, with first automatic exchanges expected in 2027 and 2028. Targeted capacity‑building activities are supporting legal transposition and operational readiness, strengthening countries’ ability to respond to emerging risks linked to digital assets.
The Global Forum Secretariat delivered bilateral technical assistance to 15 Latin American countries in 2025, and over 1 600 officials (54% of whom women) from 17 Latin American countries participated in 27 training and experience‑sharing events. More than 3 000 officials completed Global Forum e‑learning courses, while the certified trainers from the “Train the Trainer” programme collectively trained more than 800 tax officials domestically.
Tax Transparency in Latin America 2026 is a flagship publication of the Latin America Initiative, a regional effort launched in 2018 with the signing of the ministerial Punta Del Este Declaration, to promote the implementation and effective use of international tax transparency standards tailored to the priorities of Latin American countries. Its release is a key deliverable of the 14th meeting of the Latin America Initiative, held on 25-26 May 2026 in Lima, Peru, and co-organised by the National Superintendency for Customs and Tax Administration (SUNAT) and the Global Forum Secretariat.
About the Global Forum
With over 170 members, the Global Forum is the leading multilateral body mandated to ensure that jurisdictions around the world adhere to and effectively implement the standard on transparency and exchange of information on request (EOIR) and the standards of automatic exchange of information (AEOI), covering financial accounts under the Common Reporting Standard (CRS) and crypto-asset transactions under the Crypto-Asset Reporting Framework (CARF). These objectives are achieved through robust monitoring and peer review processes. The Global Forum also runs an extensive capacity-building programme to support its members to implement the standards and help tax authorities make the best use of cross-border information sharing channels.
The Global Forum capacity-building programme is supported by the following development partners, with specific contributions from the Spanish Agency for International Development Cooperation (AECID) to the Latin America Initiative:
