Acoss (Agence Centrale des Organismes de Sécurité Sociale) is the French national agency responsible for managing the treasury of the general scheme of Social Security. It coordinates and steers the network of URSSAF (Unions de Recouvrement des Cotisations de Sécurité Sociale et d'Allocations Familiales), which are responsible for collecting social security contributions and taxes from employers and self-employed workers in France. Acoss plays a vital role in financing France's social protection system, ensuring the funding for health insurance, family benefits, pensions, and unemployment benefits.
Serves as the central administrative and strategic hub for Acoss, overseeing national collection strategies, financial management for social security, IT systems, and coordination of the URSSAF network.
Modern office building (often referred to as 'Acropolis') designed for administrative functions, equipped with advanced IT infrastructure to manage vast amounts of financial data and national operations. Emphasis on security and accessibility.
Professional, mission-driven, and collaborative, focused on public service, accuracy in financial management, and efficient operation of the social security collection system. Emphasis on expertise in social legislation, data management, and IT.
The strategic core for the financial stability of France's social security system, processing billions of euros in contributions and ensuring the operational effectiveness of the nationwide URSSAF network.
As a French national agency, Acoss's primary operations are domestic. Its global presence is mainly through international cooperation with equivalent social security institutions in other countries, sharing expertise, participating in international social security forums, and managing contributions for situations involving international workers (e.g., French citizens working abroad or foreign nationals working in France under specific agreements). It does not operate 'offices' globally in a commercial sense but engages in cross-border administrative collaboration and adherence to international social security agreements.
