In order to recruit staff, a business must submit an operating declaration to the Joint Social Security Centre (Centre commun de la sécurité sociale - CCSS) in order to register as an employer.
This operating declaration enables the CCSS to assign a registration number to the business and the risk class for their business activities.
Who is concernedAny new employer, natural or legal person that wishes to recruit staff for the first time.
A company that wishes to recruit personnel must:
- have published its articles of association in the Official Journal (Mémorial C);
- or submit a copy of the constitutional documents together with its operating declaration.
Natural persons who wish to recruit staff must first have requested a business permit from the General Directorate for Small and Medium-Sized Enterprises. The General Directorate will automatically forward the permit to the CCSS.
How to proceed
All new employers must register with the CCSS in order to recruit personnel.
The employer must submit an operating declaration within 8 days of entry into service of the 1st employee hired.
If the business permit application was submitted online, the employer can use the pre-filled form which is automatically generated and stored in his business eSpace.
The data to be provided in the operating declaration concern the business, the employer and the person in charge in the Grand Duchy.
Note: the operating declaration enables the business to register with the CCSS as an employer. This declaration should not be mistaken for the entry declaration which must be made for every newly recruited employee in order to register him with the social security.
The CCSS will automatically inform the Accident Insurance Association (Association d'assurance accidents - AAA) that the employer is registered.
Business will pay their premiums to the accident insurance according to a single rate set each year by ministerial order approving the contribution rate for accident insurance contributions.
Employers' mutual insurance scheme
The CCSS also registers the employer with the employers' mutual insurance scheme (Mutualité des employeurs), which determines the contribution class applicable. Businesses are divided into 4 contribution classes. Any new compulsory or voluntary insured person is paying contributions in class 2 until the end of the financial year following the year in which he/she joined the scheme. Subsequently, the class applicable will be reassessed each year according to the level of financial absenteeism of the staff during the past year.
Certificate of affiliation
Following the registration via the operating declaration, the CCSS sends a certificate of affiliation with the business registration number and the risk class allocated to the registered business address.
This certificate of affiliation can be requested at any time from the CCSS by telephone, fax or post.
An employer can also request at any time, by electronic means:
- a certificate indicating the number of employees at a given date;
- a certificate indicating the total wage bill in a given year;
