A cross-holding structure in Luxembourg places two or more entities in mutual ownership. Each entity holds shares in the other. Control does not flow in a single direction. The Registre de Commerce et des Sociétés (RCS) records the formal layer of that structure. It does not resolve where effective control sits.
The angle here is control: who holds voting rights, who can block a resolution, and what a shareholder can enforce against the structure as filed. The RCS provides the starting point. The ceiling of that starting point is stated before any payment is made.

Access to the RBE is restricted following CJEU C-37/20. The RCS alone does not identify the natural person in ultimate control. Access conditionRCS filings are accessible to any requester. The RBE requires a demonstrated legitimate interest for access beyond the restricted baseline. Cross-holding visibilityMutual shareholdings appear in the articles and shareholder lists only to the extent each entity has filed updated documents. Gaps between filing dates create a structural blind spot.Luxembourg accommodates cross-holdings across its principal corporate forms: the société à responsabilité limitée (Sàrl), the société anonyme (SA), and holding vehicles under the 1929 or SOPARFI regimes. Each entity in the structure has its own RCS file. The files are not linked by the registry system.
A cross-holding between two Sàrls means Entity A holds a share in Entity B, and Entity B holds a share in Entity A. Both shareholdings must appear in the respective articles or shareholder lists. If one entity has not filed an updated list, the cross-holding is visible on one side only.
The RCS file for each entity contains:
For an SA, the shareholder register is not filed with the RCS. Registered shares are recorded in the company's own register, held at its seat. Bearer shares were abolished under the 2014 law on dematerialisation. Nominative shares in an SA are therefore traceable — but only through the company's internal register, not through the RCS.

Control in a cross-holding is not a single fact. It is a set of positions: who holds a blocking minority, who appoints the board, who can call a general meeting, and who can prevent a resolution from passing.
The articles of association filed at the RCS state the voting rules. For a Sàrl, the articles typically specify the majority required for ordinary and extraordinary resolutions. For an SA, the Luxembourg Companies Law of 10 August 1915 (as amended) sets default thresholds, which the articles may modify.
A cross-holding creates a structural question: if Entity A and Entity B each hold shares in the other, and both are controlled by the same natural person, that person's effective voting weight across both entities may exceed what any single shareholding percentage suggests. The RCS does not compute this. It records each shareholding in isolation.

Luxembourg transposed the Fourth and Fifth Anti-Money Laundering Directives through the law of 13 January 2019, creating the Registre des bénéficiaires effectifs (RBE). Every Luxembourg entity subject to the law must file the identity of its beneficial owner — defined as the natural person holding, directly or indirectly, more than 25% of shares or voting rights, or exercising control by other means.
In a cross-holding structure, the 25% threshold calculation is not straightforward. If Entity A holds 30% of Entity B, and Entity B holds 30% of Entity A, the indirect ownership calculation depends on the chain, not the face value of either holding. The RBE filing reflects what the entity itself has declared. It is not independently verified by the registry.
Following the CJEU judgment in Joined Cases C-37/20 and C-601/20 (WM and Sovim, November 2022), public access to the RBE was suspended in Luxembourg. Access is now restricted to:
The legitimate interest standard is applied by the Luxembourg Business Registers (LBR). It is not automatic. A foreign requester must establish the basis for the request. The outcome is not guaranteed.

A shareholder in a Luxembourg entity holds rights defined by the Companies Law and the articles. The filed articles state what those rights are. The question of enforceability is separate from the question of what is on record.
From the filed documents, the following can be established:
In a cross-holding, the practical question is whether a minority shareholder in Entity A can exercise rights against Entity A when Entity A's manager is also the manager of Entity B, and Entity B holds a blocking stake in Entity A. The articles and the Companies Law define the formal answer. The RCS provides the documents. The analysis of what those documents mean for a specific position is outside the scope of a registry report.

Luxembourg entities above certain thresholds are required to file annual accounts with the RCS. The thresholds are set by the law of 19 December 2002 (as amended). Small entities may file abbreviated accounts. Micro-entities may be exempt from filing a full balance sheet.
For a cross-holding structure, the consolidated accounts — if filed — show the group as a whole. Standalone accounts show each entity separately. The relationship between the two reveals whether the cross-holding is reflected in the carrying value of investments.
Where financial statements are filed, they are accessible through the RCS. Where an entity is exempt or has not filed within the statutory deadline, the RCS file contains no financial data for that period. The absence of a filing is itself a fact.

The RCS records what has been filed. It does not record what has not been filed, what has changed since the last filing, or what has been agreed outside the articles.
Specific limits in a Luxembourg cross-holding analysis:
Shareholder lists. For a Sàrl, the shareholder list is filed when changes occur. Between filings, the RCS reflects the last known position. A transfer of shares that has not yet been filed is not visible.
SA shareholder register. For an SA, the internal nominative share register is held at the company's seat. It is not part of the RCS file. Access requires a formal request to the company or a court order.
Shareholders' agreements. Voting agreements, tag-along rights, drag-along rights, and pre-emption arrangements are typically set out in a shareholders' agreement. These are not filed. They are not visible from the RCS.
RBE access. The beneficial owner declaration is filed but not publicly accessible. Establishing the natural person in ultimate control requires either a legitimate interest request to the LBR or access through an obliged entity.
Indirect control. The RCS records direct shareholdings. A chain of three entities, each holding a minority in the next, is not resolved by the registry into a single control percentage. That calculation requires analysis across multiple files.
Filing currency. The RCS does not guarantee that filed documents reflect the current legal position. The gap between a corporate event and its registration can be days or months.
The ceiling of what the sources allow is stated before payment. Where a fact cannot be established from the filed record, the report states that — and names the level at which the chain breaks.

What does the RCS show about a cross-holding between two Luxembourg Sàrls? The RCS shows the shareholder list for each Sàrl as last filed, the articles of association, and the identity of managers. If each Sàrl has filed an updated list reflecting its shareholding in the other, both sides of the cross-holding are visible. If one side has not filed, only one side appears.
Can the beneficial owner of a Luxembourg holding structure be identified from public sources? Not from public sources alone. The RBE holds beneficial owner declarations, but public access was suspended following the CJEU judgment of November 2022. Access requires a demonstrated legitimate interest or a request through an obliged entity acting within AML obligations.
Does a shareholders' agreement affect control in a Luxembourg cross-holding? A shareholders' agreement can define voting arrangements, pre-emption rights, and transfer restrictions that override or supplement the articles. These agreements are not filed with the RCS and are not visible from the registry record. Their existence can sometimes be inferred from the articles, but their content cannot be established from filed documents.
What is the difference between a Signal and a Standard report for a Luxembourg cross-holding? Signal establishes the filed record: who owns what, who manages, and where the filing gaps are. Standard adds the financial statements and a reading of the voting thresholds from the articles. Extended adds the RBE application and a cross-entity control map.
How current is the RCS record? The RCS reflects the last filed document. There is no statutory deadline that guarantees same-day registration of corporate events. A change in shareholders or managers may not appear in the RCS for days or weeks after it occurs.
