Mexico's IMSS uncovers 55,000 fake workers, exposing massive payroll fraud

The Mexican Institute of Social Security (IMSS) identified a phantom employer that had registered about 55,000 fictitious workers. The scheme, revealed after a business in San Pedro, Coahuila discovered 300 bogus affiliates, inflated employment figures and generated losses for legitimate employers. IMSS eliminated the fraudulent payroll, explaining the drop in official employment reported for May. The institute uses risk‑modeling and on‑site inspections to detect such false registrations, which can also affect workers’ pension rights when spurious contribution weeks are removed.

June data showed a rebound in formal job creation, with 61,000 new positions—the strongest monthly increase since 2021—partly driven by platform‑based workers. However, overall employer registrations remain down, marking a second consecutive year of decline and the longest negative streak in over two decades. The combined reports highlight both the impact of the fraud on Mexico’s labor statistics and the broader challenges facing the formal employment market.
