Mexico CFDI Tax Reform 2026: New Controls, Validity, and Legal Consequences

The Mexico CFDI tax reform 2026 is part of the proposed amendments to the Federal Tax Code (CFF), expected to take effect on January 1, 2026.

Its main objective is to strengthen the SAT’s auditing powers and combat the issuance and use of Digital Tax Receipts (CFDI) that represent simulated or non-existent transactions.

These changes reinforce traceability, authenticity, and legal accountability for both issuers and recipients.
