Services for authorised representatives on MyGuichet.lu

1. Access to the certified business eSpace

To access CCSS services on behalf of a principal, the authorised representative must certify their business eSpace. To do so, the principal must designate the authorised representative when submitting their own certification request. If the principal did not designate the authorised representative during this request, they may submit a new certification request including the authorised representative without affecting their own access rights. The authorised representative social security numbers provided in the request must correspond to those assigned by the CCSS: 13 digits for legal entities and 15 digits for self-employed persons.

The certification procedure is described in detail on the dedicated certification page ausführlich beschrieben.

As part of this procedure:

  • The CCSS sends the access codes directly to the authorised representative.
  • The principal provides the security codes to the authorised representative.

The combination of these two codes enables the authorised representative to certify their business eSpace.

The CCSS services available on MyGuichet.lu are organised by activity area, each providing access to a range of services. For example, the "Affiliations" activity area allows users to consult employee affiliation data, while the "Remuneration and work incapacities" activity area allows users to consult declared salary information.

The principal should restrict the authorised representative's access to only those activity areas for which they are responsible.

Managing business eSpaces

The authorised representative may create up to 4 business eSpaces (one per activity area) and add authorised users to them. An activity area can only be assigned to one business eSpace, whereas a business eSpace may contain up to 4 activity areas.

Example

An employer has three employees (Employee A, Employee B and Employee C) with the following responsibilities:

  • Employee A is responsible for entry and exit declarations as well as salary declarations. This employee also requires access to Employer Mutuality the settings of the Employers’ Mutual Insurance (Mutualité des employeurs - MDE)
  • Employees B and C are responsible for accounting activities.

If the employer does not wish to grant the same access rights to all three employees (it is recommended to grant only the access rights required), they may create two business eSpaces:

  • one business eSpace certified for the business areas "Affiliations", "Employer data" and "Remuneration and work incapacities", to which Employee A is added;
  • one business eSpace certified for the business area "Calculation, billing and accounting", to which Employees B and C are added.

3. Procedures

Declarations via SECUline

Authorised representatives who already submit declarations via SECUline (DECSAL, DECMAL, DECAFF, DEMMAT)  may continue to use this communication channel.

Declarations currently submitted on paper

Authorised representatives who currently submit declarations on paper (salaries, work incapacities or entry or exit declarations) are encouraged to switch to digital declarations:

  • via SECUline, particularly if they manage a high volume of declarations or wish to integrate these data flows directly into their management software (subject to accounting);
  • via MyGuichet.lu for all other authorised representatives.

Other procedures available to all authorised representatives on MyGuichet.lu, regardless of whether they use SECUline or not

The authorised representative may also carry out the following procedures:

  • request for direct debit of social security contributions;
  • request for reimbursement of a credit balance.

4. Receiving monthly account statements via eDelivery

The eDelivery service enables CCSS documents to be received in a MyGuichet.lu business eSpace instead of by post. One of its advantages is a shorter delivery time. However, the receipt of account statements depends on the authorised representative's situation and on whether the eDelivery service has been activated.

Authorised representative using SECUline AND receiving all CCSS correspondence on behalf of the principal

If the authorised representative meets both of the following conditions:

  • they submit the principal's declarations via SECUline;
  • they receive all CCSS correspondence intended for the principal;

then account statements will continue to be sent by post, regardless of the status of the eDelivery option.

Other situations

In all other cases, if the eDelivery service is activated, the account statement is deposited in the certified business eSpaces of both the authorised representative and the principal.

For both parties to receive the account statement via eDelivery, both business eSpaces (the employer's and the authorised representative's) must be certified for the business area "Calculation, billing and accounting" and the eDelivery service must be activated for that specific business area.

For example, if the authorised representative has certified their business eSpace and activated the eDelivery service, while the principal has not certified their business eSpace, the account statement will only be deposited via eDelivery in the authorised representative's business eSpace.
