The Mexican fiscalization framework mandates the issuance of CFDI fiscal receipts through certified PACs. CFDI as digital documents must be validated and stamped before being considered fiscally valid. Requirements also include long-term archiving with integrity controls.
Mexico
Mexico’s fiscalization system is based on the mandatory use of CFDI (Comprobante Fiscal Digital por Internet), an electronic fiscal receipt in XML format. Issuers must use a PAC (Authorized Certification Provider) to validate and digitally stamp each fiscal document before it is sent to the recipient. This ensures compliance with the SAT (Tax Administration Service) requirements. The fiscalization model also supports continuous monitoring by tax authorities and covers various sales processes.
