URSSAF (Union de Recouvrement des cotisations de Sécurité Sociale et d'Allocations Familiales) is the network of French bodies responsible for collecting social-security contributions from employers and self-employed individuals. Contributions collected by URSSAF finance health insurance (assurance maladie), family allowances (allocations familiales), occupational accident and disease coverage, and other branches of the French social-protection system.
Every employer in France must register with the relevant regional URSSAF before the first employee starts work. Monthly or quarterly declarations are submitted via the Déclaration Sociale Nominative (DSN), a single digital payroll report that feeds contribution data directly to URSSAF and other agencies. Failure to register, under-declare wages, or pay late results in penalties, late-payment surcharges, and potential personal liability for company directors.
For foreign companies employing staff in France, either through a local entity or via an employer of record (EOR), URSSAF registration and ongoing compliance are non-negotiable obligations. The total effective employer contribution rate typically runs between 40 and 45 per cent of gross salary, depending on the sector, applicable collective agreement, and any exemption schemes in force.
