New measures strengthening quality, accuracy, and timeliness of the data filed with the Luxembourg Business Registers

Luxembourg has strengthened corporate compliance obligations following the amendment of the Law of 19 December 2002 on the RCS and the Law of 13 January 2019 establishing the RBO. The new rules, which entered into force on 1 February 2025, aim to reinforce the corporate filing and publication compliance for entities within their scope.

In this context, the LBR has introduced a series of measures to improve the quality, accuracy, and timeliness of filings on RCS and RBO. As part of these measures, it has deployed an automated monitoring system to detect missing, expired or inconsistent data and identify non-compliance with mandatory filing formalities.

Failure to comply with these requirements may lead the LBR to initiate a formal procedure and impose administrative measures or sanctions, including:

• A public mention of non-compliance visible on the LBR website.
• The issuance of extracts and certificates flagging non-compliance.
• Daily penalty payments of €40, capped at a total of €3,600.
• Deletion of the entity from the LBR, without dissolution or loss of legal personality.
• Referral of the case to the public prosecutor as a last resort.

All registered entities are therefore requested to promptly verify the status of their data recorded in the RCS and RBO—such as their address, shareholder(s), board composition, disclosed persons on the RBO, financial statements status—and, where necessary, to update incomplete, outdated or inconsistent information.

To reduce the risk of disruptions in entities’ administration and operations, entities are strongly advised to remain fully aligned with the new requirements. Our Corporate Secretarial (CoSec) team can support you with data reviews, identification of gaps or inconsistencies, and the preparation and submission of any necessary updates to the LBR.
