SAT Updates CFDI 4.0 Catalogs for Customs Declarations
Jul
The Mexican Tax Administration Service (SAT) has published an update to the CFDI 4.0 catalogs, effective July 17, 2026. This update adds new records related to customs declarations and customs broker licenses while keeping the technical structure (XSD) used for generating electronic tax invoices unchanged.
For companies operating with Microsoft Dynamics 365 Business Central, staying up to date with these changes is essential to ensure compliance with Mexican tax regulations and avoid inconsistencies when issuing CFDIs.
