In Luxembourg, the Audit Law lays down that only réviseurs d’entreprises agréés (approved statutory auditors) and cabinets de révision agréés (approved audit firms) may carry out statutory audits.

The cabinets de révision (audit firms) and the réviseurs d’entreprises (statutory auditors) wishing to carry out statutory audits must: 

  • obtain the “réviseurs d’entreprises” title for natural person or be recognised as “cabinet de révision” for legal person;
  • be approved by the CSSF.

Procedure to obtain the title

Natural persons

Upon application, the CSSF grants the title ”réviseur d’entreprises” to:

  • candidates who have passed the examination of professional competence;

Recognition of audit firms approved in another Member State

In Luxembourg, the Audit Law lays down that only réviseurs d’entreprises agréés (approved statutory auditors) and cabinets de révision agréés (approved audit firms) may carry out statutory audits.

However, a derogation to this principle exists that allows an audit firm approved in another Member State to carry out statutory audits in Luxembourg provided that the key audit partner carrying out the statutory audit on behalf of the audit firm is a réviseur d’entreprises agréé (approved statutory auditor).

While exercising its activity in Luxembourg, the audit firm must comply with the Audit Law as do the cabinets de révision agréés (approved audit firms) and réviseurs d’entreprises agréés (approved statutory auditors) and will be subject to public oversight of the audit profession with respect to the statutory audits carried out in Luxembourg.

These audit firms will be registered by the CSSF and included in the public register in this capacity.

The audit firms wishing to benefit from this derogation must fill in Form C (LU) and Annex Form C (LU) and send them duly signed and with the required supporting documents attached to it (supaudit@cssf.lu).

Not later than eight working days as from receiving the written request and provided that the file containing the information necessary to verify the prerequisites is complete, the CSSF registers the audit firm. It allocates a personal ID number to the audit firm which must be indicated in all subsequent exchanges with the CSSF.

The personal ID number allocated by the CSSF is a unique and permanent number.

Recognition of service providers from other Member States

In accordance with the Audit Law and the Grand-Ducal Regulation of 18 December 2009 determining the conditions for the recognition of service providers from other Member States in order to carry out any duties exclusively entrusted to réviseurs d’entreprises (statutory auditors) by way of free provision of services, the professionals that wish to carry out in Luxembourg, on a temporary and occasional basis, any duties entrusted exclusively to réviseurs d’entreprises (statutory auditors) by the law, by way of free provision of services and without having a stable establishment, are required to notify the CSSF before their first provision of services.

The CSSF may refer to the consultative commission to verify the professional qualifications of the providers that wish to exercise by way of free provision of services in Luxembourg.

Two cases must be distinguished:

  • the consultative commission issues a positive opinion on the professional qualification: the CSSF informs the provider that the service provision may be performed;
  • the consultative commission issues a negative opinion on the professional qualification: the CSSF informs the provider that s/he must first take an aptitude test to perform the requested service provision.
