Luxembourg SOPARFI structures operate under the Luxembourg Law of 10 August 1915 on commercial companies
(Loi du 10 août 1915 concernant les sociétés commerciales), which remains the central legislative act governing corporate entities in the country. The current SOPARFI regime replaced the former Luxembourg “Holding 1929” regime, which was abolished following European Commission state aid investigations in the late 2000s.
Companies are registered with the
Registre de Commerce et des Sociétés (RCS Luxembourg) and corporate documentation is filed with the Luxembourg Business Registers (LBR).
Corporate filings, including annual accounts, are submitted electronically through the Luxembourg filing platform managed by the LBR.
In practice, most holding companies are established in the form of:
- Société à responsabilité limitée (S.à r.l.)
- Société anonyme (S.A.)
The S.à r.l. structure is more commonly used for international holding platforms due to its flexible governance structure and lower minimum capital requirements.
