E-invoicing in Mexico

Live Confidence: medium Checked 21 Jul 2026
ModelClearance · CFDI via authorised PAC → SAT
Required formatCFDI 4.0 XML (Anexo 20)
TimelineLive since 2011 · CFDI 4.0 current

Who is in scope

All taxpayers. B2B, B2G and B2C. Invoices must be validated and stamped by an authorised certification provider (PAC) before they are legally valid. Five-year archiving for issuer and recipient.

Key dates

  • 2011–2014 CFDI phased in and became mandatory for all taxpayers.
  • Apr 2023 CFDI 4.0 became the sole valid version, tightening recipient-data matching against SAT records.
  • 1 Apr 2026 Digital service providers and marketplace platforms obliged to give SAT direct access to tax and operational data (Rule 2.9.21, art. 30-B CFF); 'Notice of Access' due by 30 Apr 2026.
  • 24 Apr 2026 Hydrocarbons and petroleum products supplement required on CFDIs for fuel sales.
  • 1 May 2026 Permanent online SAT access to platform information takes effect.
What practitioners get burned by

Two regimes are often conflated: issuing a compliant CFDI, and the newer obligation on digital platforms to give SAT live access to their data. Also note art. 29-A Bis now lets SAT demand photographic or video evidence that the underlying transaction occurred, and simulated CFDIs carry criminal liability from 2026.
