Mexico is becoming an increasingly attractive destination for expansion among European Union sellers. This is due in part to the rapidly growing e-commerce market, the strong presence of Amazon and its Latin American counterpart, Mercado Libre, and Mexico’s status as a more accessible alternative to the U.S. market. Furthermore, Mexico is a pioneer in e-invoicing…
E-invoicing in Mexico
CFDI (Comprobante Fiscal Digital por Internet) is an electronic invoice composed of two components: an XML file (technical format) and an optional PDF (visual representation for the recipient). The invoice must be validated by the Mexican tax authority – the Servicio de Administración Tributaria (SAT). Taxpayers are required to submit the invoice to the authority in real time. Since 2014, the obligation to issue CFDI applies to all entities registered for tax purposes in Mexico – including foreign businesses.
Before a business can access the CFDI system, it must first take several key steps. This includes obtaining an electronic signature (FIEL) and a Digital Seal Certificate (Certificado de Sello Digital, CSD) from the tax authority. Additionally, it is mandatory to use a PAC (Proveedor Autorizado de Certificación) – a government-authorized provider that validates and submits invoices to SAT.
The responsibilities of a PAC include:
- Receiving the XML – formatted invoice prepared by the taxpayer
- Authorizing the invoice (i.e., formally validating the data)
- Submitting the approved document to SAT, which assigns it a unique UUID and returns it within 72 hours with a digital seal, ready to be forwarded to the recipient.
Are there penalties for not issuing a CFDI?
Yes. Failure to issue electronic invoices can result in penalties for non-compliance with e-invoicing obligations. In addition, the recipient loses the right to deduct VAT. It can also hinder cooperation with local partners, who may refuse to accept invoices not authorized under the CFDI system.
Does a foreign company need a physical presence in Mexico to issue CFDI invoices?
No. A physical presence in Mexico is not required. However, the company must be VAT registered, hold an electronic signature (FIEL), and cooperate with a local PAC. In practice, this often necessitates working through a local representative or advisor.
Must CFDI invoices be issued in Spanish?
Yes. All CFDI documentation – including both the XML and PDF files – must be issued in Spanish, as per the requirements of the Mexican tax authority. If needed, companies may attach unofficial translations for foreign clients.
Is a PDF file sufficient as an invoice?
No. The PDF is only a visual representation of the invoice for reference. Only the XML file, approved by SAT and containing the UUID, is considered the legally valid version of the invoice in Mexico.
