Starting April 1, 2023, only CFDI v4.0 with Carta Porte v2.0 will be valid. This change is mandatory for all taxpayers in Mexico who transport goods and merchandise within the Mexican Territory. This means that any other version of the CFDI or Carta Porte will not be accepted by the tax authorities.

The CFDI, or Comprobante Fiscal Digital por Internet, is an electronic invoice used in Mexico to document transactions between businesses. It is required by law for all businesses to issue CFDIs for sales made within the country.

Version 4.0 of the CFDI includes new adjustments and validations to be carried out by the certification provider for the issuance of the Carta Porte complement.

The Carta Porte Complement is an additional document that must be included with the CFDI for transport services provided within Mexico.

The Carta Porte v2.0 became effective on December 1, 2021, and it became mandatory starting on January 1, 2022. This means that all taxpayers who transport goods and merchandise within Mexico must use Carta Porte v2.0 from this date forward.
