On 12 January 2026, Guatemala became the 148th member of the Organisation for Economic Co-operation and Development (OECD)/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS), reinforcing the country's commitment to international tax cooperation and the adoption of globally accepted tax standards. This incorporation represents a significant milestone in Guatemala's tax policy, as it formally joins a multilateral forum that promotes coordination among jurisdictions to combat base erosion and profit shifting practices and to strengthen the integrity of tax systems.

Among the most relevant aspects of this accession are the following:

• Participation in the Inclusive Framework allows Guatemala, on an equal footing with other Inclusive Framework member jurisdictions, to actively engage in the discussion, implementation and evaluation of the BEPS Actions, as well as other international tax matters of common interest.
• Participating in the Inclusive Framework demonstrates a commitment to strengthen fiscal transparency, protect national tax revenue and improve tax certainty through the progressive alignment of Guatemala's tax system with international best practices promoted by the OECD and the G20.
• By joining the Inclusive Framework, Guatemala commits to implementing the four BEPS minimum standards: Actions 5 (Combating Harmful Trade Practices), 6 (Preventing Tax Treaty Abuse), 13 (Country-by-Country Reporting), and 14 (Mutual Agreement Procedure). Although membership entails an obligation to adopt these standards, there is no specific implementation deadline.
• This participation should help promote stronger tax enforcement and greater confidence in Guatemala's tax system, contributing to economic growth and the mobilization of domestic resources through clearer rules, enhanced cooperation among tax administrations and common standards of corporate responsibility.

Adherence to the Inclusive Framework on BEPS marks an important step in the modernization of the Guatemalan tax system and its integration into the international tax architecture.

Future Global Tax Alerts will provide updates on regulatory developments and specific commitments arising from this development.
