Is public disclosure of shareholders required in Belgium?

Shareholder disclosure in Belgium operates on two parallel tracks: a publicly accessible company register and a beneficial ownership register with restricted access. Not every shareholder';s name appears on a freely searchable public database, but significant ownership interests and ultimate beneficial owners must be registered and, in most cases, can be inspected by third parties with a legitimate interest. This guide covers which entities are affected, what information must be disclosed, who can access it, and what happens when obligations are ignored.

Shareholder disclosure in Belgium is the obligation to record and, to varying degrees, make available information about the persons or entities that hold shares or ownership interests in a Belgian company. The obligation arises from two distinct legal frameworks: the Companies and Associations Code (Wetboek van vennootschappen en verenigingen, or WVV), which governs corporate filings with the Crossroads Bank for Enterprises (Kruispuntbank van Ondernemingen, or KBO), and the Anti-Money Laundering Law of 18 September 2017, which established the Ultimate Beneficial Owner (UBO) register administered by the Federal Public Service Finance.

These two frameworks serve different purposes. The KBO filing is primarily a commercial and administrative record. The UBO register is a transparency and anti-money laundering tool. Together they create a layered system in which some shareholder information is fully public, some is accessible only to parties with a demonstrated legitimate interest, and some remains confidential unless a court or competent authority orders otherwise.

Foreign founders frequently assume that Belgian company law mirrors the most restrictive jurisdictions they have encountered elsewhere. In practice, Belgium sits in the middle of the European spectrum: more transparent than some offshore structures, but less automatically public than, for example, the United Kingdom';s Companies House model.

The WVV applies to all Belgian legal entities, including the private limited liability company (besloten vennootschap, or BV), the public limited company (naamloze vennootschap, or NV), the cooperative company (coöperatieve vennootschap, or CV), and others. Each entity type has its own share register requirements.

For the BV, the most commonly used vehicle for foreign-owned businesses, the company must maintain an internal share register. This register records the names and addresses of all shareholders, the number of shares held, and any transfers or pledges. The register is not automatically published in full, but it must be made available to shareholders and, in certain circumstances, to third parties with a legitimate interest.

For the NV, shares may be in registered or dematerialised form. Registered shares are recorded in the company';s share register. Dematerialised shares are held through a recognised account-keeping institution, and the identity of holders is known to that institution but not necessarily to the general public.

The UBO register obligation applies broadly. Companies, foundations, non-profit associations, trusts, and similar legal arrangements must identify and register their ultimate beneficial owners. A beneficial owner is generally any natural person who directly or indirectly holds more than 25% of the shares or voting rights, or who exercises control through other means. Where no natural person meets the threshold, the senior managing official is registered as the beneficial owner by default.

The KBO is a public register. Anyone can search it online and retrieve basic company information, including the company';s registered address, legal form, date of incorporation, and the identity of directors and statutory auditors. However, the full shareholder register of a BV or NV is not automatically published in the KBO. What appears there is the company';s constitutional information, not a live list of every shareholder.

The UBO register operates differently. Under the current framework, derived from the Fourth and Fifth Anti-Money Laundering Directives transposed into Belgian law, the following information about beneficial owners is accessible to the general public: name, month and year of birth, nationality, country of residence, and the nature and extent of the beneficial interest held.

More detailed information - including the exact date of birth and full address - is accessible only to competent authorities such as the Financial Intelligence Processing Unit (Cel voor Financiële Informatieverwerking, or CFI), notaries, lawyers, accountants, and other obliged entities acting in a professional capacity. Members of the public and journalists may access the public portion of the UBO register by submitting a request and demonstrating a legitimate interest.

A non-obvious requirement is that beneficial owners may request partial restriction of access to their UBO data if they can demonstrate that disclosure would expose them to a disproportionate risk, such as fraud, kidnapping, or extortion. This exemption is narrow and must be applied for individually. It does not remove the obligation to register; it only limits who can see the data.

When shares in a BV change hands, the transfer must be recorded in the company';s internal share register. Under the WVV, share transfers in a BV are subject to approval requirements unless the articles of association waive them. The transfer is effective between the parties from the moment of agreement, but it is enforceable against the company and third parties only once it is entered in the register.

For the NV, the procedure depends on whether shares are registered or dematerialised. Transfers of registered shares are recorded in the share register. Transfers of dematerialised shares are executed through book-entry in the account-keeping system.

When a transfer results in a change to the beneficial ownership structure - for example, when a new shareholder crosses the 25% threshold - the UBO register must be updated. Belgian law requires that the register be kept accurate and up to date at all times. In practice, this means that any change in beneficial ownership must be reported to the UBO register within one month of the change occurring.

A common mistake among foreign founders is treating the UBO registration as a one-time formality completed at incorporation. In reality, it is a continuous obligation. Each time the ownership structure changes - through a share transfer, a new investment round, a restructuring, or a change in control - the register must be updated promptly.

Failure to comply with UBO register obligations carries meaningful consequences under Belgian law. The Anti-Money Laundering Law provides for administrative fines ranging from moderate to substantial amounts, applied per violation and per period of non-compliance. The Federal Public Service Finance has the authority to impose these fines directly, without requiring a court proceeding.

Beyond administrative fines, non-compliance can affect the company';s ability to operate. Notaries and other obliged entities are required to verify UBO registration before completing certain transactions, including real estate transfers and corporate restructurings. A company that has not fulfilled its UBO obligations may find that a notary refuses to proceed until the register is updated.

Directors bear personal responsibility for ensuring that the UBO register is accurate. Under the WVV, directors owe a duty of care to the company and its stakeholders. Persistent failure to maintain accurate records can expose directors to civil liability claims, particularly if a third party suffers loss as a result of relying on inaccurate information.

In practice, the Belgian authorities have moved from an awareness phase to an enforcement phase. Obliged entities such as banks and accountants are required to report discrepancies they discover between the UBO register and information they hold. This creates a secondary enforcement mechanism that operates independently of direct inspections.

Consider a foreign entrepreneur who sets up a BV in Belgium as a wholly owned subsidiary of a holding company incorporated outside the EU. The holding company is the direct shareholder, but the natural person who controls the holding company is the ultimate beneficial owner. Both the holding company';s shareholding and the natural person';s beneficial ownership must be registered. The UBO register will show the natural person';s name, nationality, country of residence, and the nature of their interest. The holding company';s identity will appear in the company';s constitutional documents filed with the KBO.

A second scenario involves a Belgian startup with five co-founders, each holding 20% of the shares. Because no single founder exceeds the 25% threshold, none of them qualifies as a beneficial owner under the standard ownership criterion. In this case, the company must assess whether any founder exercises control through other means - for example, through a shareholders'; agreement that gives one person veto rights or the ability to appoint a majority of the board. If such control exists, that person must be registered as a beneficial owner. If no natural person can be identified, the senior managing official - typically the CEO or managing director - must be registered by default.

These scenarios illustrate why a mechanical application of the 25% threshold is insufficient. The beneficial ownership analysis requires a substantive review of the actual control structure, not just the nominal shareholding percentages.

Does the Belgian UBO register show the full address and date of birth of shareholders?

The public portion of the UBO register does not display a beneficial owner';s full address or exact date of birth. The public record shows name, month and year of birth, nationality, country of residence, and the nature and extent of the interest held. Full address and exact date of birth are accessible only to competent authorities and obliged entities such as notaries, lawyers, and accountants acting in a professional capacity. A beneficial owner who faces a specific personal risk may apply for a restriction on even the public portion of their data, though this exemption is granted only in narrow circumstances and does not remove the underlying registration obligation.

How quickly must changes in beneficial ownership be reported, and what does it cost to register?

Changes in beneficial ownership must be reported to the UBO register within one month of the change. There is no separate registration fee charged by the Federal Public Service Finance for UBO filings; the cost is primarily the professional time required to prepare and submit the update. In practice, most companies use an accountant, lawyer, or company secretary to manage UBO filings, and professional fees for a straightforward update are typically modest. Delays beyond the one-month window can trigger administrative fines, so prompt action after any ownership change is strongly advisable.

Can a Belgian company keep its shareholder list entirely private?

Complete privacy is not achievable for Belgian companies. The UBO register requires disclosure of beneficial owners to the public in summary form and to competent authorities in full. The internal share register of a BV is not published automatically, but it must be accessible to shareholders and, in certain legal proceedings, to courts and regulators. For listed NVs, additional disclosure obligations apply under securities law. The most that a beneficial owner can achieve is a partial restriction of their UBO data on personal safety grounds, which limits public access but does not affect access by authorities. Structures that attempt to obscure beneficial ownership through nominee arrangements without genuine economic substance are subject to scrutiny under Belgian anti-money laundering rules.

Belgium requires meaningful shareholder disclosure through two complementary systems: the KBO for corporate filings and the UBO register for beneficial ownership. Public access to the UBO register is real but limited to summary information. Full details are reserved for authorities and obliged entities. Compliance is an ongoing obligation, not a one-time filing, and enforcement has intensified in recent years.
