From 1 October 2025, entities will be unable to submit RCS filings unless the Luxembourg national identification number (LNIN) of relevant individuals is provided.

Purpose

Persons and entities registered with the RCS (Luxembourg Trade and Companies Register) will have to communicate the Luxembourg national identification number – "LNIN" (also known as a "CNS number or "matricule") of all natural persons registered with the RCS. Once provided to the RCS, the LNIN will not be publicly accessible.

Existing and future entities must therefore be updated, for natural persons resident and non-resident in Luxembourg.

For natural persons who are not Luxembourg residents, the RCS will proceed to assign an LNIN number when registering a new entity or filing a change in the relevant entity.

Luxembourg Business Registers Clarifies RBE Filings For Companies Held By A Trust Or Foundation

Luxembourg's Business Register has clarified how beneficial ownership rules apply when companies are held through trusts or foundations, requiring entities to register the underlying trust or foundation's beneficial owners rather than applying the standard corporate ownership test. This interpretation, issued without a transitional period, means affected entities must immediately review their beneficial ownership filings to ensure compliance with the Register's position.
