Luxembourg Register of Beneficial Owners (RBE): 2026 Guide

The Luxembourg Register of Beneficial Owners (RBE), also known as the Luxembourg UBO register, records the natural persons who ultimately own or control covered entities. Administered by Luxembourg Business Registers, RBE Luxembourg supports AML compliance and corporate transparency.

The Luxembourg RBE is an ongoing compliance obligation. Ownership or control changes must be reported, and 2025 reforms strengthened access and correction procedures. In 2026, authorities inspected 73 entities and found 23 with inaccurate, incomplete or outdated RBE information.

The latest Luxembourg RBE guidance covers companies owned through trusts or foundations, including registration, beneficial-owner identification, filing requirements, access rules and record maintenance. For businesses conducting KYB or AML checks, the Luxembourg UBO register is an important source of information, but it should be used alongside independent ownership verification.

What Is the Luxembourg Register of Beneficial Owners?

The Luxembourg Register of Beneficial Owners, or Registre des bénéficiaires effectifs (RBE), records the natural persons who ultimately own or control Luxembourg-registered entities. Established in 2019, it supports corporate transparency and AML/CFT compliance. Unlike the RCS, which records legal and corporate details, the RBE Luxembourg framework identifies a company’s ultimate beneficial owners (UBOs).

The Luxembourg UBO register is therefore focused on the individuals behind a legal entity rather than only the entity’s registered shareholders, directors or corporate structure.

What Laws Govern the Luxembourg RBE in 2026?

Luxembourg’s Register of Beneficial Owners (RBE) is governed by a framework of laws and regulations designed to promote transparency and support AML/CFT compliance.

Understanding these rules helps businesses meet Luxembourg RBE filing requirements, maintain accurate beneficial ownership information, and comply with current access and verification obligations under the Luxembourg UBO register framework.

Law of 13 January 2019

The Law of 13 January 2019 established Luxembourg’s Register of Beneficial Owners (RBE) and requires covered RCS-registered entities to identify and report the natural persons who ultimately own or control them. This supports AML/CFT compliance and corporate transparency.

The law forms the foundation of RBE Luxembourg and sets out the core obligation to identify, register and maintain information about beneficial owners.

Grand-Ducal Regulation of 15 February 2019

The Grand-Ducal Regulation of 15 February 2019 sets out the practical rules for submitting and updating RBE declarations, paying registration fees, and accessing RBE information. Together with the 2019 RBE Law, it provides the operational framework for Luxembourg’s beneficial ownership requirements and the Luxembourg UBO register.

Law of 23 January 2025

The Law of 23 January 2025 reshaped Luxembourg RBE access and enforcement for 2026. It clarified access for authorities, AML/CFT professionals and individuals with a legitimate AML/CFT interest, while strengthening discrepancy reporting and penalties for inaccurate or missing UBO information.

Under Article 8, authorised users and AML professionals generally must report identified errors or omissions within 30 days. This means that information found through RBE Luxembourg checks may need to be compared with corporate records and reported or corrected where discrepancies arise.

What the 2022 CJEU Judgment Changed

On 22 November 2022, the CJEU ruled that unrestricted public access to beneficial ownership registers could violate privacy and data-protection rights. Luxembourg therefore suspended general public access to the RBE, while preserving access for authorities, regulated AML/CFT professionals and qualifying applicants.

The Luxembourg UBO register was not abolished. Instead, the rules governing who may access Luxembourg RBE information changed.

Who Is a Beneficial Owner Under Luxembourg Rules?

Under Luxembourg RBE rules, a beneficial owner is the natural person who ultimately owns or controls an entity, including through companies, partnerships, trusts or other legal structures.

Identification involves three steps: check for ownership exceeding 25%, assess control through voting rights or other arrangements, and record senior managing officials only when no individual can be identified after reasonable investigation.

This analysis is central to RBE Luxembourg compliance because the register must ultimately identify natural persons rather than simply recording another company or legal arrangement.

Ownership of More Than 25%

A person who owns strictly more than 25% of a Luxembourg entity’s capital is generally presumed to be its beneficial owner. However, ownership below that threshold does not automatically exclude someone. Voting rights, shareholder agreements and indirect ownership must also be reviewed.

The threshold is strictly more than 25%, not “25% or more.” Businesses preparing a Luxembourg UBO register filing should therefore avoid treating a 25% holding as automatically meeting the ownership threshold without reviewing other forms of control.

Control Through Other Means

A person may qualify as a beneficial owner without exceeding the 25% ownership threshold if they control the entity through other means, such as dominant voting rights, shareholder agreements, appointment rights, intermediate companies or other governance arrangements.

For example, someone holding 20% of the shares may still be the Luxembourg UBO if a voting agreement gives them decisive influence. Ownership percentages should therefore be assessed alongside actual control when completing an RBE Luxembourg analysis.

Businesses should also trace indirect ownership through intermediate companies and other legal structures before concluding that no individual can be identified.

Senior Managing Officials as the Fallback

Senior managing officials are recorded as beneficial owners only when reasonable efforts fail to identify a natural person through ownership or control. This fallback may apply when ownership is widely dispersed, documentation is incomplete or no individual exercises decisive influence.

It does not allow a company to skip its ownership analysis or automatically list its CEO. Businesses should document their investigation, explain why no UBO was identified, and register the appropriate senior managing official or officials in the Luxembourg UBO register.

Important 2026 Update for Companies Owned by Trusts or Foundations

Companies owned through trusts or foundations require careful beneficial ownership analysis. On 19 August 2026, Luxembourg Business Registers issued Circular LBR 26/01 stating that companies should generally report the natural persons behind the underlying trust or foundation, including the settlor, trustee, protector, beneficiaries or other individuals exercising ultimate control.

This guidance is particularly relevant to RBE Luxembourg filings involving complex ownership structures. A corporate trustee, foundation or other legal entity should not automatically be treated as the final beneficial owner where the individuals behind the structure can be identified.

LBR states that Circular LBR 26/01 is explanatory rather than legally binding. However, it indicates how Luxembourg authorities may interpret beneficial ownership rules and anticipates principles under Article 55 of the EU’s new AML Regulation.

Businesses should document their ownership analysis, retain relevant trust or foundation records, and avoid treating a corporate trustee or foundation as the final beneficial owner. Where appropriate, the Luxembourg UBO register filing should reflect the natural persons connected with the trust or foundation and any individuals exercising ultimate control.

2027 Watch: EU Beneficial Ownership Rules

Regulation (EU) 2024/1624 will generally apply from 10 July 2027, further harmonising EU AML and beneficial ownership requirements. Companies with trust, foundation or complex international ownership structures should review their Luxembourg RBE procedures now, including UBO identification, ownership documentation, control analysis and ongoing monitoring.

Preparing early can help businesses keep RBE Luxembourg information accurate and ensure that their Luxembourg UBO register records remain consistent with broader EU beneficial ownership requirements.

How to File a Luxembourg RBE Declaration

Filing a Luxembourg RBE declaration requires identifying the entity’s ultimate beneficial owners, gathering the required information, and submitting it through the Luxembourg Business Registers (LBR) portal.

The process helps ensure compliance with Luxembourg beneficial ownership, RBE filing, KYB, and AML requirements. It is also the main process for keeping information accurate in the RBE Luxembourg framework and the Luxembourg UBO register.

Step 1: Identify the beneficial owner(s)

Map the entity’s complete direct and indirect ownership structure, including intermediate companies, trusts, foundations and shareholder agreements. Identify every natural person who owns strictly more than 25% of the capital or exercises control through voting rights, appointment rights or other means.

If no individual can be identified after a reasonable ownership and control analysis, register the relevant senior managing official(s) as the fallback beneficial owner(s). This step is essential for accurate Luxembourg RBE registration, Luxembourg UBO register reporting and UBO verification.

Step 2: Collect required information

Gather the beneficial owner’s surname, first name(s), nationality, full date and place of birth, country of residence, precise address and applicable identification numbers. You should also document the nature and extent of the beneficial interest, such as direct ownership, indirect ownership or control through other means.

Keep supporting corporate records, ownership charts and identification documents available. These materials help demonstrate how the beneficial owner was determined and support Luxembourg KYB, AML and Luxembourg RBE compliance checks.

Step 3: Access the LBR portal

Submit the Luxembourg RBE declaration electronically through the Luxembourg Business Registers (LBR) online portal. The registered entity or its authorised representative should ensure that the filing is made through the correct account and for the correct RCS-registered entity.

Authentication may be completed using supported methods such as LuxTrust, GouvID or an eligible eIDAS certificate. Before starting, confirm that the filer has the authority to submit the beneficial ownership declaration to the RBE Luxembourg register.

Step 4: Select the beneficial-owner procedure

Enter the entity’s RCS number and select the appropriate beneficial-owner registration or modification procedure. Check the entity details carefully before proceeding to avoid filing information against the wrong Luxembourg company.

Choose the relevant category, such as identified beneficial owner(s), senior managing official(s) where no beneficial owner can be identified, or the applicable listed-company treatment. Ensure the selected procedure matches the ownership analysis and supporting documentation required for the Luxembourg UBO register.

Step 5: Select the correct beneficial-owner category

When filing through the Luxembourg Business Registers (LBR) portal, select the category that accurately reflects the entity’s ownership structure. Available options generally include identified beneficial owners, senior managing officials where no beneficial owner can be identified after a reasonable analysis, and stock exchange listing where the relevant entity qualifies for that treatment.

Do not select senior managing officials simply as a shortcut. The Luxembourg RBE requires businesses to assess direct ownership, indirect ownership and control through other means before using the senior-management fallback. Listed-company treatment should also be applied only where the registered entity itself meets the applicable requirements.

Step 6: Submit the declaration and supporting documentation

Submit the Luxembourg RBE declaration electronically through the LBR portal, together with any required supporting documents. The filer must also provide a declaration of honour confirming that they are authorised to act for the registered entity and that the information submitted is accurate and complete.

Supporting evidence may be requested where ownership is complex, the beneficial owner lacks a Luxembourg identification number, or the entity is relying on a special filing treatment. Keep corporate records, ownership charts and verification documents available in case LBR or another competent authority requests evidence for the RBE Luxembourg filing.

Step 7: Pay the filing fee

After completing the RBE filing, pay the applicable Luxembourg Business Registers fee. Current LBR guidance lists the standard registration or modification fee as €15 excluding VAT, although businesses should confirm the amount and payment requirements before submitting the declaration.

The fee generally applies when registering beneficial owners or updating existing Luxembourg RBE information in the Luxembourg UBO register. Keep the payment confirmation with the filing receipt and supporting records as part of the entity’s ongoing beneficial ownership compliance file.

Step 8: Maintain the information

Luxembourg RBE compliance does not end with the initial filing. The registered entity must monitor changes in ownership, voting rights, control arrangements, beneficial-owner details and senior managing officials used as a fallback, then update the register within the applicable one-month deadline.

Businesses should periodically compare their RBE entry with current corporate documents, shareholder registers and ownership charts. Keeping beneficial ownership information accurate, complete and up to date helps reduce the risk of discrepancies, enforcement action and Luxembourg RBE penalties.

What Is the Deadline for RBE Registration and Updates?

Luxembourg entities generally have one month to register or update their beneficial ownership information with the Registre des bénéficiaires effectifs (RBE) from the date they become aware, or should reasonably become aware, of a relevant change.

This Luxembourg RBE deadline applies after share transfers, ownership-percentage changes, restructurings, changes in voting or control rights, the appointment of a new controlling person, updates to a beneficial owner’s identity or residence details, or changes involving senior managing officials recorded as fallback beneficial owners.

Because RBE compliance is ongoing, companies should maintain a documented ownership-monitoring process and promptly submit any required RBE modification through Luxembourg Business Registers (LBR). This helps ensure that information remains current across the RBE Luxembourg framework and the Luxembourg UBO register.

Who Can Access Luxembourg's RBE in 2026?

The Luxembourg Register of Beneficial Owners (RBE) is not generally open to the public in 2026. Following the CJEU’s 22 November 2022 judgment, Luxembourg suspended unrestricted access to protect privacy and personal-data rights.

Under the Law of 23 January 2025, access remains available to authorities, AML/CFT-regulated professionals, certain public bodies and institutions, and applicants who can demonstrate a legitimate AML/CFT interest. The RBE remains a valuable KYB and AML resource, but it is no longer freely searchable. Access to RBE Luxembourg information therefore depends on the applicant’s legal status and purpose.

What Counts as a Legitimate Interest?

A legitimate interest must relate to combating money laundering or terrorist financing, not simple curiosity or general commercial research. Examples may include journalists investigating financial crime, qualifying EU-based AML/CFT organisations, and parties considering a transaction with a Luxembourg company who need to assess beneficial ownership and financial-crime risks. Certain authorities may also qualify. Applicants should support their request, as legitimate interest does not provide unrestricted public access to the Luxembourg UBO register.

What Can Authorised Users See?

The information available depends on the applicant’s status and purpose. Luxembourg authorities generally have the broadest access for supervisory, investigative and AML/CFT purposes.

Regulated professionals, self-regulatory bodies and approved legitimate-interest applicants may access relevant beneficial-owner details, including names, nationalities, birth details, residence countries and the nature and extent of ownership or control. Precise addresses and identification numbers are generally excluded for non-authority users to protect privacy. The scope of access should therefore be confirmed before relying on Luxembourg RBE information for KYB or AML decisions.

Can a Beneficial Owner Restrict Access to Their RBE Information?

Yes. A beneficial owner may request restricted access to their Luxembourg RBE information in exceptional cases involving risks such as fraud, kidnapping, blackmail, harassment, violence or intimidation. Similar protections may apply to minors and individuals lacking legal capacity.

Restrictions are not automatic. Applicants must provide evidence of the specific risk. An approved restriction generally lasts only while the risk continues, up to three years, with renewal possible. A restriction limits access to information in the RBE Luxembourg system and the Luxembourg UBO register; it does not remove the underlying obligation to provide accurate beneficial ownership information.

Can Businesses Rely Solely on the RBE for KYC or KYB?

No. The Luxembourg RBE is useful for confirming declared ownership, but it does not replace independent KYC, KYB or AML due diligence. Regulated professionals may consult the RBE Luxembourg register when identifying UBOs, but cannot rely on it exclusively. 

A robust process should combine RCS records, corporate documents and ownership mapping, then compare the results with the Luxembourg UBO register, resolve discrepancies, verify UBOs, conduct sanctions, PEP and adverse-media screening, apply risk-based CDD or EDD, and monitor changes over time.

What Are the Penalties for RBE Non-Compliance?

Luxembourg treats Register of Beneficial Owners (RBE) compliance as an ongoing obligation, not a one-time filing. Entities and beneficial owners may face fines of €1,250 to €1,250,000 for failing to register or submitting inaccurate, incomplete or outdated information. LBR may also require corrective action when it identifies discrepancies in a Luxembourg RBE filing.

Under the 2025 enforcement framework, ignoring an LBR verification request may lead to deficiency notices, publication of the review, a €40 daily penalty and, if unresolved, administrative deregistration or referral to the authorities. Accurate UBO identification, timely RBE Luxembourg updates and documented KYB checks are therefore essential.

RBE Enforcement in Luxembourg in 2026

Luxembourg’s Register of Beneficial Owners (RBE) is an actively enforced compliance obligation, not a one-time filing. In 2026, authorities announced systematic checks, and 73 entities were reportedly inspected and cited, including 23 cases involving inaccurate, incomplete or outdated information.

This shows that companies can remain non-compliant even after filing with the Luxembourg UBO register if ownership, control rights or senior managing officials change without a timely update. Companies should regularly review their Luxembourg RBE registration, compare it with corporate records and correct discrepancies within the applicable deadline.

Common Luxembourg RBE Mistakes to Avoid

Avoiding common Luxembourg RBE compliance errors helps businesses keep beneficial ownership records accurate, meet filing deadlines, and reduce AML and KYB risks.

The following mistakes can lead to inaccurate RBE information, failed due diligence, administrative action, or significant penalties.

Registering another company as the beneficial owner - A company or other legal entity cannot be the ultimate beneficial owner (UBO). Businesses must trace ownership and control through intermediate structures to identify the relevant natural person. If no individual can be identified after a reasonable assessment, senior managing officials may be registered as a fallback in the RBE Luxembourg filing.

Automatically using the CEO - Listing the CEO automatically is a common Luxembourg RBE mistake. Senior managing officials should generally be recorded only after ownership and control have been assessed and no natural-person beneficial owner can be identified. The CEO’s role alone does not establish UBO status under the Luxembourg UBO register framework.

Assuming the RBE is publicly searchable - The Luxembourg Register of Beneficial Owners is not publicly accessible. Following the CJEU’s 2022 judgment, access is limited to authorities, AML/CFT professionals and certain persons with a legitimate interest. Businesses should therefore distinguish between the Luxembourg RBE as a compliance resource and unrestricted public access to RBE Luxembourg information.

Treating the RBE as definitive KYB evidence - An RBE extract supports Luxembourg KYB and AML checks but does not conclusively prove ownership. Regulated professionals should compare it with corporate records, verify the natural-person UBOs, and investigate any discrepancies before relying on the information recorded in the Luxembourg UBO register.

Ignoring indirect or overseas ownership - Beneficial ownership may be hidden behind holding companies, trusts, partnerships or overseas entities. Luxembourg companies should trace ownership and control across jurisdictions, assess voting rights and identify the natural persons at the end of the chain. Cross-border ownership mapping and enhanced due diligence are especially important for complex or high-risk structures and for maintaining accurate Luxembourg RBE records.

Bottom Line

For Luxembourg companies, RBE compliance means identifying the correct UBOs, tracing ownership and control, and keeping Luxembourg RBE filings accurate as structures change. The RBE supports KYB and AML checks but does not replace corporate documents, KYC, sanctions screening or ongoing due diligence.

With authorities actively reviewing inaccurate or outdated information, companies should also prepare for broader EU requirements from 2027. Binderr Services brings company verification, ownership mapping, UBO identification, KYC, AML screening, risk assessment and monitoring into one workflow.
