Version 3.3 of Mexico’s CFDI e-invoicing programme has remained unchanged since 2017. CFDI stands for Comprobante Fiscal Digital por Internet, which means ‛digital tax return by internet’. Version 3.3 included some major changes, such as introducing the ‘Payment Complement’ (Complemento para Recepción de Pagos or just Pagos) for reporting payment received. Shortly before version 3.3 was due to be adopted, the SAT granted an extension of several months to get used to the changes. Now that CFDI 3.3 version has been in use for several years, a leap to CFDI version 4.0 is on the horizon.
CFDI 4.0 obligatory from 1st May 2022 at the latest
According to the Mexican tax authorities SAT, there will be a three-month transition period. Companies will need to have adopted the new CFDI version 4.0 by May 1, 2022. Currently, all certified providers, otherwise known as “PACs”, are scheduled to go live with CFDI version 4.0 between January 1, 2022 and May 1, 2022 at the latest. To this end, the SAT has told all PACs in advance, i.e. the most important IT providers and software vendors, to expect major changes in their e-invoicing programme.
What are the biggest changes in CFDI 4.0?
Compared to the changes introduced by CFDI 3.3 in 2017/2018, the changes expected in version CFDI 4.0 seem less complex. Version 3.3, for example, introduced “payments” as a new document type. At the time, many of our customers struggled with the challenges of correctly assigning received (partial) payments to the corresponding outgoing invoices. It doesn’t look like version 4.0 of CFDI will be introducing new document types like the above. However, we shouldn’t underestimate the changes it does contain.
The changes mainly concern the structure of the CFDI 4.0 format, processes such as the electronic waybill (“E-Waybill” or “Carta Porte”), export invoices, withholdings (“Withholdings” or “Retenciones”), cancellations of invoices (“Cancellations” or “Cancelación”) and of payments (“Payments” or “Pagos”), etc.
Phases of CFDI 4.0 implementation
The preparatory phase, scheduled for November and December 2021, is already underway. The Mexican tax authorities SAT are intending the subsequent implementation to work as follows:
- The implementation phase begins on 1st January 2022 and needs to be completed by 30th April 2022.
In the implementation phase, which also doubles as a testing and bug fixing period, the two versions CFDI 3.3 and CFDI 4.0 will exist alongside each other. The SAT first published the specifications for CFDI version 4.0 on 10th December 2021. Both the short advance notice in November 2021 and the tight implementation phase until the end of April 2022 pose a number of challenges for companies liable for Mexican tax and their service providers.
With well over 10 years of obligatory use of an e-invoicing clearance regime, Mexico is an oldtimer and pioneer in the world of Continuous Transaction Controls (CTCs). While Mexico’s SAT has continued to expand and improve the invoice clearance process, there is still a lot of untapped potential in their system, not least in the ability to automate invoice processing for recipients. Alongside an e-invoicing service for Mexico, which includes a PAC service and archiving, SEEBURGER BIS E-Invoicing Services also offer you several ways to automate the bookkeping for your incoming and outgoing invoices. Equally, SEEBURGER can provide deep process integration with any ERP system, such as the seamless integration of SAP S/4HANA via the SAP API Business Hub. We are an established cloud services provider with many years of experience in understanding the various e-invoicing requirements in EU countries and beyond, and pride ourselves on meeting these requirements them with a one-stop solution.
