An internal audit of the Social Security Institute (IPS) uncovered a scheme to conceal employer social security contribution debts involving more than 50 companies and individuals, with an estimated financial loss of over PYG 7.670 billion (Guaraní 7.670 billion). The irregularities were identified in a January 2026 report covering the period from January 2024 to May 2025.
The modus operandi involved altering data from the Single Taxpayer Registry (RUC) and ID numbers in the Electronic Information Registry (REI) system, used by the IPS to track contributions and employer obligations. Through these modifications, the debts of defaulting companies were transferred to shell companies or even to deceased individuals, allowing the original debtors to appear with no outstanding balances on their statements.
Among the largest amounts illegally transferred are Empresa de Transporte Padre Fidel Maíz SRL, with PYG 885 million; Da Vinci SA, with PYG 658 million; Silvero Báez Claudio, with PYG 552 million; Paludo SA, with PYG 500 million; Campos Ortiz Jaime Blas Narciso, with PYG 430 million; Jorge Samudio Ferreira, with PYG 426 million; and Multi-Servicios SA, with PYG 355 million. Also on the list are well-known companies from various sectors, including Milano Internacional SA, Víctor y Romi SRL, Rancho Ysapy SA, Agro Ganadera Monte Alto SA, Makin'g Group SA, Mercado Móvil SRL, Importquartz SA, Osorio Card SA, Carrocería Paraguaya SA (Carpasa), Empresa de Transporte Ñane Reta SA, and Tatter SRL.
The audit identified 54 initial records and five additional cases with multiple irregular modifications, some dating back to 2010. Among the cases with repeated alterations are Laureano Espínola, with changes between 2014 and 2024; Estudio Libertad SA Consultores e Abogados, with 19 irregular alterations in 2017; Antonio Romero Escobar; Hugo Cantero López; Héctor Luis Núñez Cabañas; Henririch Giesbretch Kauenhowen; and Cristian Eduardo Quintana. Combined, the five additional cases account for PYG 445.7 million in unpaid contributions.
The report identified around 14 IPS employees linked to the irregular modifications. Employee Analía Aide Machuca Caballero, using the username "anamachu," accounted for the highest number of detected alterations, with 55 modifications. María Lorena González ("malgonza") reported the misuse of her username and password. Renán Leguizamón ("rleguiza") retained administrator privileges even after requesting the revocation of his access. Also named are Fidelina Almada Benítez ("falmada"), Jazmín Rocío Díaz López ("jardiaz"), Albert Martínez Romero, Rodrigo Fabián Zelaya, Lis Mabel Pereira Krissel, Albino Vallejos Gracia, Juan Manuel Álvarez, Elizabeth Frey, Robert Acosta, Luis Adolfo Bobadilla Colman, Liliana Patiño, and Osvaldo Bareiro.
The document concludes that the facts may constitute crimes of data tampering and computer sabotage. The alterations allowed companies with large social security obligations to appear with no registered debts, facilitating procedures, document requests, participation in public tenders, and other processes requiring proof of compliance with the IPS.
