Adrián Bueno May 4, 2026

This newsletter gathers the primary tax and legal criteria, resolutions, and updates relevant in Mexico, issued by authorities such as PRODECON, SAT, the Judiciary, TFJA, and the SCJN.

Among the most prominent topics are criteria that strengthen the legal certainty of taxpayers, clarifications on the exercise of auditing powers, the scope of tax refunds, as well as new regularization programs and reference parameters for measuring fiscal risks.

Furthermore, it incorporates relevant legal theses and resolutions that impact the interpretation and application of tax provisions, along with recent publications in the Official Gazette of the Federation.

This compendium aims to provide a clear and updated view of the regulatory environment, facilitating the identification of risks, opportunities, and key actions for compliance and decision-making.

We invite you to review the full document to learn the details of these changes and their impact on your organization's operation and compliance.
