Amendment to Article 29 of the INFONAVIT Law Version 3.6.7 of the SUA for the calculation and payment of amortizations

27/08/2025

The Mexican Social Security Institute (IMSS) released version 3.6.7 of the Single Self-Determination System (SUA) to ensure the proper implementation of the amendment to Article 29 of the INFONAVIT Law.

This update enables the correct calculation of amortizations not withheld due to insufficient salaries of workers on medical leave or absences during July and August 2025. The deadline for payment of these amortizations is September 17, 2025, making it essential for employers to promptly implement the required adjustments in the SUA. Pérez-Llorca México’s Social Security team is available to provide guidance on the operational implementation of this new version of the system.
