On June 7, the Decree amending, adding, and repealing various provisions of the Social Security Law regarding digital tools was published in the Official Gazette of the Federation (the “DOF”).

Previously, electronic notifications were optional and required the express consent of the employer or obligated party. Through this reform, the formal operation and administration of the new IMSS Mailbox is established as an electronic communication system, in which the Mexican Social Security Institute (the “IMSS”) can issue summons, notifications, orders of any act, requests for information, or administrative resolutions in digital documents.

Individuals, in turn, can submit promotions, requests, notices, comply with their obligations and requirements, and make inquiries about their fiscal and administrative status before the Institute.

It is important to highlight that actions carried out through the IMSS Mailbox, which is implemented on the IMSS website www.imss.gob.mx, will have the same legal effects as documents signed in handwriting and, consequently, will have the same probative value.

When individuals do not enable the IMSS Mailbox, provide incorrect information, do not register, or do not update their contact details, the IMSS may make notifications via public notices.

Therefore, within 60 days following the publication of the aforementioned reform, the IMSS must issue the procedures and services available in the IMSS Mailbox, as well as its general rules for operation.

Until these general rules are published, the “General Guidelines for the Use of the IMSS Mailbox,” approved by the Technical Council through Agreement ACDO.AS2.HCT.240620/170.P.DIR, published on July 9, 2020, in the DOF, will apply.
