Luxembourg's CNS (Caisse Nationale de Santé) is administered by the CCSS (Centre Commun de la Sécurité Sociale) and groups together health, pension, dependency and accident insurance. Combined employee + employer contributions amount to roughly 24–25% of capped gross salary, with the cap set at five times the minimum social wage — EUR 13,856.63/month or EUR 166,279.56/year from 1 June 2026 (index 992.24).
2026 CNS Contribution Rates
Health (assurance maladie): 6.10% total, split 3.05% employee + 3.05% employer. Pension (assurance pension): 16% total, split 8% employee + 8% employer. Dependency contribution (assurance dépendance): 1.4%, paid entirely by the employee, on income reduced by an annual abatement of EUR 8,313.96 (25% of the unskilled SSM). Accident insurance: 0.7%–1.0% paid by the employer only, depending on occupational risk class. Mutualité employer health fund: ~0.60% average. State contributes additional shares to pension and health.
The EUR 166,280 Contribution Ceiling
All contributions (except dependency) are capped at five times the minimum social wage. With the unskilled monthly SSM at EUR 2,771.33 under index 992.24, the maximum cotisable is EUR 13,856.63/month or EUR 166,279.56/year from 1 June 2026. Above this ceiling, no additional CNS contribution is owed. Dependency uses a different base: gross income minus an abatement of 25% of the unskilled SSM (EUR 692.83/month, EUR 8,313.96/year), uncapped. This makes Luxembourg's effective rate regressive for very high earners.
Self-Employed vs Employee Treatment
Self-employed workers (indépendants) pay both shares of health and pension — about 24.10% (8% × 2 + 3.05% × 2 + 1.4% + accident estimated). They are entitled to the same benefits (healthcare, retirement, parental leave) but bear the full employer-share cost. CNS membership is automatic the moment self-employment is registered with the Ministry of the Middle Classes.
How Indexation Changed the 2026 CNS Ceiling
Luxembourg contributions are not fixed for the calendar year — they move with the échelle mobile des salaires. An index tranche triggered on 1 June 2026 lifted the applicable index from 968.04 to 992.24, a 2.5% rise, which pushed every threshold up on the same day:
- Unskilled monthly SSM — EUR 2,771.33 (EUR 3,325.59 for qualified workers, 120%)
- Maximum cotisable (all regimes except dependency) — EUR 13,856.63/month, EUR 166,279.56/year
- Dependency abatement (25% of unskilled SSM) — EUR 692.83/month, EUR 8,313.96/year
- Minimum cotisable for pensioners (health insurance, 130%) — EUR 3,602.72
Practically, this means a payslip from May 2026 and one from July 2026 use different ceilings, so a high earner whose contributions had already capped out will see CNS deductions restart in June. Contribution rates themselves (6.10% health, 16% pension, 1.4% dependency) did not change — only the base did.

Cross-Border Workers and Sources
About 50% of Luxembourg's workforce is cross-border (France, Belgium, Germany). EU Regulation 883/2004 means CNS contributions are paid in Luxembourg and benefits are coordinated with the home country. Cross-border workers may receive healthcare in either country and access Luxembourg parental and family benefits. Source: CCSS (Centre Commun de la Sécurité Sociale), CNS. Updated 2026-08-04.
