2023-05-03 | NSP-84The Norms Committee of the Central Reserve Bank of El Salvador issued Technical Standards NSP-84 to mandate the implementation of a Single Payroll System (SPU) for pension and social security contributions. These regulations require the Financial System Superintendence to manage a centralized database and a unified electronic system, obligating pension administrators, the ISSS, and employers to use this platform for real-time data sharing and declaration. The standards define specific terms, user access protocols, validation controls, and a phased implementation timeline effective from May 19, 2023, with full compliance required starting with the June 2023 payroll period.
