IMSS Modalidad 40: Requirements to enroll for pension

Mexico's Mexican Social Security Institute (IMSS) offers Modalidad 40, a voluntary continuation program for individuals who have left formal employment but wish to maintain and strengthen their contribution history for retirement. Officially known as "Continuación Voluntaria en el Régimen Obligatorio," this mechanism allows former workers to continue making contributions independently, aiming to secure a higher pension amount.

A significant advantage of Modalidad 40 is the ability for participants to select their Base Contribution Salary. Since this figure heavily influences pension calculations, many workers strategically use this scheme as part of their retirement planning. Participants also retain protection under the insurance for disability and life, along with benefits related to old age and retirement.

However, enrollment is not universal. To qualify, individuals must have been previously covered under the IMSS mandatory regime and have at least 52 weeks of contributions within the five years preceding their job separation. Crucially, the application must be submitted within 12 months of the employment termination date; missing this window may forfeit the opportunity to join the program.

The application process can be completed online through the IMSS portal or in person at IMSS offices. Both methods require the applicant's CURP, Social Security Number (NSS), and a valid email address. The chosen contribution salary cannot be lower than the last registered salary before separation and cannot exceed 25 times the UMA (Unit of Measurement and Update). IMSS typically processes applications within five business days.
