The Registre de Commerce et des Sociétés (RCS) is Luxembourg's statutory commercial register. It records the legal existence of companies, their registered management, and the documents filed over the life of the entity. Control — who directs the company and on what authority — is the first question any cross-border buyer asks. The RCS is the first place that question is put to an official source.
What the RCS does not answer is equally important. Shareholder identity below the level of the registered entity, and the identity of the person who ultimately instructs management, are not disclosed by this register. That ceiling is stated before any work begins.

The RCS operates under the amended law of 19 December 2002 on the commercial and companies register. Every commercial entity established in Luxembourg — société anonyme (SA), société à responsabilité limitée (Sàrl), société en commandite par actions (SCA), and others — must register before commencing activity.
The register holds two categories of data. The first is the identity layer: name, number, legal form, registered seat, and date of formation. The second is the document layer: articles of incorporation, amendments to articles, resolutions appointing or removing managers and directors, and annual accounts where filing is mandatory.
Searches run by name or by registration number. The official portal returns the current status of the entity and a list of filed documents. Individual documents are available for download against payment of the applicable fee. The fee schedule is published by the registrar and is subject to periodic revision; the current tariff should be confirmed directly with the RCS before any retrieval.
The RCS is maintained by the Luxembourg Business Registers (LBR), a public-law body. Extracts issued by the LBR carry official status and are accepted by courts and notaries in Luxembourg and across EU member states.
Control: what the register establishes and where it stops
For a cross-border buyer, the control question has two layers. The first is formal authority: who is named as manager or director, and what powers does the instrument of incorporation assign to that person. The RCS answers this directly. The current managers of a Sàrl and the board members of an SA are named in the register. The articles on file state the scope of their authority — whether they act alone, jointly, or within defined limits.
The second layer is economic control: who instructs management, who holds the economic interest, and whether the registered structure reflects the actual decision-making chain. The RCS does not answer this. Luxembourg's beneficial ownership register — the Registre des bénéficiaires effectifs (RBE) — is a separate instrument. Following the Court of Justice of the EU ruling in joined cases C-37/20 and C-601/20 (November 2022), public access to UBO registers across EU member states was suspended or restricted. The RBE is no longer accessible to the general public without a demonstrated legitimate interest. Access conditions are subject to ongoing regulatory development and must be confirmed with the registrar before any request is submitted.
The gap between the RCS and the RBE is the structural limit of what official sources disclose in Luxembourg. A chain of registered entities — a Luxembourg holding company above a subsidiary — produces a register entry at each level, but the person at the top of the chain is not named in either register unless they hold a management role.
Shareholder rights: what the filed documents show
Shareholder rights in a Luxembourg company are defined in the articles of incorporation and, where applicable, in shareholders' agreements. The articles are filed with the RCS and are publicly accessible. A shareholders' agreement is a private contract and is not filed; it does not appear in the register.
The articles state the share capital, the number and class of shares or parts sociales, the voting rules, the quorum requirements for general meetings, and the conditions for transfer of shares. For a Sàrl, the list of shareholders (associés) and their respective holdings may appear in the articles or in a separate instrument filed at the time of incorporation or on each subsequent transfer. Whether a current, complete list of shareholders is on file depends on the history of transfers and the form of the entity.
For an SA, shares may be in registered or bearer form. Bearer shares were abolished in Luxembourg with effect from 2014; all shares must now be registered. The register of registered shareholders is maintained by the company itself, not by the RCS. It is not publicly accessible through the commercial register.
The practical consequence: for a Sàrl, the RCS may show the original shareholders and subsequent transfers if each was notified and filed. For an SA, the RCS shows the structure and the articles; the current shareholder list is held internally and is not a public document.
Filed financial statements: availability and scope
Luxembourg law requires certain categories of company to file annual accounts with the RCS. The obligation applies to SAs, Sàrls above defined thresholds, and other entities specified by the law of 19 December 2002 as amended. Micro-entities and certain holding structures benefit from simplified filing or exemptions.
Filed accounts are available through the RCS portal. The documents are scanned filings; structured financial data is not extracted by the register. The accounts show the balance sheet, profit and loss statement, and notes as prepared under Luxembourg GAAP or IFRS where applicable. Consolidated accounts, where filed, cover the group structure as defined by the consolidating entity.
What the accounts do not show: intercompany flows that are netted at consolidation, off-balance-sheet arrangements, and the economic substance of intragroup transactions. A holding company with a single asset — a participation in a subsidiary — will show that participation at cost or at fair value depending on the accounting policy applied. The underlying asset of the subsidiary is not visible in the Luxembourg filing.
The limit of what the sources allow
The RCS is a registration and disclosure instrument, not a transparency instrument. Its ceiling is defined by what the law requires to be filed, not by what a buyer needs to know.
Four limits apply consistently across entity types in Luxembourg.
Beneficial ownership is not in the RCS. The RBE holds UBO data, but public access has been suspended following the CJEU ruling of November 2022. Access requires a demonstrated legitimate interest and is subject to conditions set by the registrar. The current access procedure must be confirmed before any request is submitted.
Shareholders of an SA are not in the RCS. The internal share register is a company document. It is accessible only to shareholders and, in certain circumstances, to courts. A buyer cannot retrieve it through the commercial register.
Shareholders' agreements are not filed. Voting arrangements, drag-along and tag-along rights, pre-emption clauses, and deadlock mechanisms exist in private contracts that are invisible to the register.
Nominee arrangements are not flagged. A registered manager acting on instructions from an undisclosed principal appears in the register identically to a manager acting on their own account. The register records the name; it does not record the instruction.
These limits are not defects in the register. They are the boundary of what official disclosure in Luxembourg covers. Work beyond that boundary requires a different instrument or a different jurisdiction's filing.
Where the sources disagree
The RCS and the RBE are maintained by the same body (LBR) but draw on different filing obligations. Discrepancies arise in two recurring patterns.
The first is timing. A change of manager filed with the RCS takes effect on publication in the Recueil électronique des sociétés et associations (RESA). A corresponding update to the RBE, if the manager is also a beneficial owner, is a separate filing obligation. The two updates may not be simultaneous. A buyer reading both registers on the same day may see different names in each.
The second is scope. The RBE records the beneficial owner as declared by the entity. The RCS records the manager as appointed by the shareholders. Where a beneficial owner exercises control through a management role, both registers will name the same person. Where control is exercised through a chain of entities, the RBE entry reflects the declaration made at the time of filing; the RCS entry reflects the current registered management. Neither register independently verifies the accuracy of the other.
A discrepancy between the two registers is itself a finding. It does not resolve the question of control; it identifies where the question requires further investigation.
FAQ
What does the RCS show about a Luxembourg Sàrl? The RCS shows the company's registration number, legal form, registered address, date of incorporation, current and former managers, and filed documents including the articles of incorporation and any amendments. For a Sàrl, the original shareholder list and subsequent transfer instruments may also be on file, depending on the history of the entity.
Can a buyer retrieve the current shareholder list of a Luxembourg SA from the RCS? No. The internal share register of an SA is maintained by the company and is not a public document accessible through the RCS. The RCS holds the articles and filed resolutions, which describe the share structure but do not identify current shareholders by name.
Is the Luxembourg beneficial ownership register publicly accessible? Following the CJEU ruling of November 2022, public access to the RBE was suspended. Access now requires a demonstrated legitimate interest. The current conditions for access must be confirmed directly with the Luxembourg Business Registers before any request is submitted.
What is the difference between the RCS and the RESA? The RCS is the register itself — the database of corporate records. The RESA (Recueil électronique des sociétés et associations) is the official gazette where filings are published. A filing takes legal effect on publication in the RESA, not on submission to the RCS. Both are maintained by the LBR.
Does the RCS show whether a company is solvent? The RCS records insolvency proceedings that have been opened and published. A negative result — no insolvency entry — does not confirm solvency; it confirms that no proceeding has been published in the register as of the date of search. A proceeding filed but not yet published will not appear.
What filed financial statements are available through the RCS? Annual accounts filed by entities subject to the filing obligation under Luxembourg law are available through the RCS portal as scanned documents. Structured data is not provided. Entities benefiting from exemptions — including certain holding companies and micro-entities — may have reduced or no filing obligations.
