Employers in Monaco must register with the Caisses Sociales de Monaco (CCSS), the body administering the general social security scheme covering health insurance, pensions, and family benefits. Employer contributions average around 35% of gross salary (range 28-40%, varying by sector and benefits provided), and employee contributions average around 13% (range 10-14%). Contributions are generally remitted monthly. Self-employed individuals contribute directly to CCSS at a flat quarterly rate (€1,095/quarter as of 2026) rather than through payroll withholding. Given the high combined contribution burden and strict CCSS reporting standards, engaging local payroll/accounting expertise is standard practice for employers operating in the Principality.
