Disability pension at the IMSS: required contribution weeks, medical report and how much you should be paid

The Mexican Social Security Institute (IMSS) has outlined the requirements for obtaining an invalidity pension as of 2026. Applicants under the 1973 Law must have a minimum of 150 weeks of contributions, while those under the 1997 Law are required to have 250 weeks. An exception to these contribution requirements applies if a medical assessment, known as the ST-4 form, confirms an invalidity level of 75% or greater.

Separately, regulations regarding unemployment subsidies for individuals over the age of 52 have been clarified. Access to these subsidies while receiving a pension is not universally prohibited; eligibility is contingent upon the specific type of benefit received, the applicant's prior employment history, and their total monthly income.
