Audit professions

Last update

In order to work in the audit profession, it is necessary to be a holder of the title statutory auditor (réviseur d'entreprises).

The title is conferred to candidates who:

  • meet the legal requirements in terms of theoretical qualification and professional integrity in order to allowed to take the professional training required;
  • meet the conditions for the professional training and continuing education;
  • have set up a professional establishment in Luxembourg or exercise their profession as a salaried worker in an audit firm.

To work as an auditor in a company (set up under the legal form of a company), the legal person must have the official title 'audit firm' (cabinet de révision).

The fulfilment of mandatory conditions is verified by the Luxembourg Financial Sector Supervisory Commission (Commission de Surveillance du Secteur Financier - CSSF) at the time of registration for the professional training and again when the title is conferred.

Certain professionals may benefit from the recognition of their professional qualifications obtained abroad and/or experience in order to gain access to the profession of auditor.

The statutory auditor / audit firm must have received an approval from the CSSF before they can carry out the statutory audit of accounts.

Who is concerned

The activities of statutory auditors (and audit firms) include audit activities which are not necessarily exclusively reserved for audit professionals, i.e.:

  • domiciliation;
  • the contractual audit of accounts;
  • tax advice;
  • administration of accounts and bookkeeping;
  • the analysis, through the use of accounting techniques, of the economic and financial situation of businesses from an economic, legal and financial standpoint.

The activities of statutory auditors (and audit firms) include audit activities, in addition to the ones mentioned before, which are exclusively reserved for audit professionals, i.e.:

  • the issue of reports on contributions other than in cash;
  • the tasks of an internal auditor in mergers/demergers;
  • the tasks of a liquidator;
  • the distribution of interim dividends;
  • the verification and certification of the annual financial statements of the National Film Fund (Fonds national de soutien à la production audiovisuelle).

The auditor may be entrusted by the fund to proceed with specific verifications.

Only approved statutory auditors (réviseur d'entreprises agréé) and approved audit firms (cabinet de révision agréé) are authorised to carry out the statutory audit of accounts in Luxembourg.

The activities of a statutory auditor are incompatible with any other activity which may affect the auditor's professional independence.
