What is the AFIP’s platform for online tax compliance?

The correct choice is SiRADIG (Sistema de Registro y Actualización de Datos de la Seguridad Social) because it is specifically designed as the platform for managing and updating information related to social security and tax compliance in Argentina. SiRADIG facilitates the registration and reporting of employees' data, making it a crucial tool for both employers and employees to ensure compliance with tax regulations.

While the other options may sound plausible, they do not align with the specific function of online tax compliance that SiRADIG provides. The TaxNet Online System, for example, is more associated with electronic filing processes but isn't as directly focused on the broader spectrum of tax compliance as SiRADIG. Similarly, the eCompliance Platform and ArgentinTax System may imply some level of tax-related services, but only SiRADIG explicitly serves the role in the context of social security data updates and ensuring compliance with tax obligations in Argentina.
