Who is obliged to use e‑Invoicing in Mexico

E-invoicing regulation in Mexico has been introduced gradually to become mandatory for all taxpayers from 2014. Mexico was the one of the earliest countries to implement that solution and is considered as a pioneer in the LATAM region.

Implementation timeline

  • January 1, 2022 - CFDI has been updated to version 4.0, which will co-exist with CFDI version 3.3 until March 2023.
  • From April 1, 2023, the only applicable version will be 4.0.

E-invoicing process description

The use of the services of the Mexican tax authorities, called SAT services, is mandatory for issuing invoices (in the case of electronic invoices, this has been delegated to certified PAC providers).

The issuer must communicate the invoice to the recipient within three days following issuance. The issuer has to be capable of providing a printed copy if this is required by the buyer.

How integrity and authenticity may be ensured?

Each invoice must be signed with the supplier's CSD (certificate issued by the tax authorities) and then sent to the Provincial Administrative Court. The PAC is obliged to verify the XML format and the signature, assign the folio (UUID), sign with the key provided to the tax authority. PAC performs these processes known as "Timbrado" and returns the result to the supplier (or service provider).
