Opening a business bank account in Luxembourg: KYC file and good practice

Opening a business bank account in Luxembourg: the principle

Quick answer. A business bank account is an account opened in the name of a legal entity (operating company, holding company, family office) for the needs of its business. In Luxembourg, opening one requires the bank to know its future customer: it reviews a KYC file before entering into any relationship.

An essential point to understand from the outset: the decision to open an account lies with the bank. A bank is free to accept or refuse to enter into a relationship, in compliance with the regulations. No adviser, lawyer or intermediary can guarantee that an account will be opened. What can be done, on the other hand, is to prepare and structure a clear and complete file that makes it easier to process.

This requirement stems from the AML/KYC compliance obligations that banks bear as entities subject to the rules on combating money laundering and terrorist financing. Understanding these obligations helps you anticipate what the bank will ask for.

Why banks review a KYC file

Luxembourg banks are obliged entities subject to customer due diligence obligations. Before opening an account, they must identify their customer, verify their identity, understand the nature of their business and the source of their funds, and identify the beneficial owner of the structure.

This review is not an incidental administrative formality: it is a regulatory obligation for which the bank answers to its supervisory authority, the CSSF (Luxembourg financial sector supervisory commission) for most of the financial sector. A poorly documented relationship exposes the bank to a compliance risk that it will not agree to take.

That is why the quality of the file matters as much as the nature of the project. A complete, consistent and documented file answers the bank's questions before it asks them, and avoids the back-and-forth that lengthens timescales.

Bear in mind too that the bank adjusts its level of requirements to the profile of the file, following a risk-based approach. A local company with a simple business does not raise the same questions as an international group with a complex shareholding. Anticipating the likely level of due diligence makes it possible to calibrate the documentation from the start and to avoid the bank having to request, as the review progresses, documents that could have been provided at the outset.

The documents generally requested

The documents required vary from one bank to another and according to the company's profile, but a common core is found in most files. It concerns the company, its directors and its beneficial owner.

On the company side, the bank generally examines the constitutional documents (articles of association, extract from the Trade and Companies Register), proof of address and, where relevant, information on the company's domiciliation in Luxembourg. On the individuals' side, it asks for identification of the directors and authorised signatories, as well as of the beneficial owner, with identity documents and supporting documents.

Added to this is information on the business (description, forecasts, main partners or expected flows) and on the source of funds and of wealth. This information allows the bank to understand how the account is expected to operate economically. The precise list is set by each bank.

The bank often also asks for information on the company's main customers, suppliers or counterparties, on the countries it deals with and on the planned transaction volumes. This information helps it check the consistency between the declared profile and the expected actual use of the account. Providing recent and legible documents and, where relevant, translated or legalised documents when the bank requires it, significantly reduces requests for additional information.

The beneficial owner at the heart of the review

Identifying the beneficial owner is a central point of any account opening file. The bank seeks to know which natural person ultimately controls the company or benefits from it. For a holding company or a multi-level structure, this means tracing the chain of ownership back to the natural persons.

A clear and documented chain of ownership makes the review considerably easier. Conversely, opaque structures, multi-jurisdictional arrangements with no apparent justification or difficulties in identifying the beneficial owner are common points of friction.

Luxembourg maintains a Register of Beneficial Owners (RBE): consistency between the information declared there and that provided to the bank is a factor in the assessment. A family office or a wealth structure benefits from preparing a clear map of its ownership in advance.

Substance and the link with Luxembourg

Beyond the documents, banks look at the company's substance and its genuine link with Luxembourg. Substance refers to the idea that the company carries on a genuine business and has resources consistent with that business, rather than being a shell with no operational reality.

The factors examined may include the location of management, the presence of human or material resources, the nature of the decisions taken in Luxembourg, or the consistency between the registered office, the business and the expected flows on the account. For many structures, domiciliation in Luxembourg goes hand in hand with consideration of substance.

Expectations of substance vary with the type of structure and its business. An operating company, a holding company and an investment vehicle do not have the same profile. Anticipating this question prevents it from becoming a late obstacle.

This requirement fits into a context in which the authorities and banks pay growing attention to the economic reality of structures. A company with no tangible business at all, and no identifiable link with Luxembourg, will be examined with greater caution. Conversely, a consistent presence, decisions taken locally and clear governance are reassuring factors for the bank approached.

The most common grounds for refusal

A refusal to open an account, or a request for information that goes nowhere, is rarely down to chance. Several recurring grounds come up, and most can be anticipated when the file is being prepared.

The most common include an incomplete file or an inconsistent one, difficulty in identifying the beneficial owner, a lack of substance or of a link with Luxembourg, a business perceived as high-risk or insufficiently explained, a poorly documented source of funds, or a profile that does not match the commercial policy or acceptance policy of the bank approached.

It bears repeating: even a flawless file does not give a right to an account, because the bank retains its discretion. But a well-built file reduces the points of friction and, if one bank refuses, makes it possible to approach another one effectively.

The same project may indeed be refused by one bank and accepted by another, as each bank has its own acceptance policy and its own appetite for a given profile. A first refusal should therefore not necessarily be read as a final obstacle, but as a sign that you should either improve the file or target a bank whose policy better matches the project.

The lawyer's role in preparing the file

The role of a law firm is not to obtain an account, but to help present the project in the best conditions. It involves understanding the structure, anticipating the bank's questions and gathering consistent and complete documentation, in line with compliance obligations.

In practice, the support may cover the structuring of the company or group, clarifying the chain of ownership and the beneficial owner, preparing the substance information, making the source of funds consistent and coordinating with domiciliation. The lawyer also helps choose the type of structure suited to the project.

This support usefully ties in with the other steps in setting up and establishing the company, from drafting the articles of association to domiciliation. Dealing with these questions together, rather than in isolation, makes it possible to build a file that is consistent from start to finish and to avoid inconsistencies between the documents given to the various parties.

Anticipating timescales and the start of the relationship

Opening a business account is not instantaneous: it requires a review by the bank, sometimes several exchanges of documents and internal checks. Timescales depend on the bank, on the complexity of the structure and on the quality of the initial file, and cannot be guaranteed in advance.

To limit the back-and-forth, it is useful to gather all the documents in advance, prepare a clear presentation of the business and of the source of funds, and have a clear map of the ownership. A file that is ready from the first submission is processed more smoothly.

It can also be useful to prepare, in addition to the documents, a concise presentation note describing the company, its business, its shareholding and the purpose of the account. Although not mandatory, this document helps the bank grasp the project quickly and shows that the approach is serious. A file structured in this way compares favourably with a simple transmission of scattered documents.

Finally, it is prudent not to overestimate the certainty of an outcome. The right approach is to maximise your chances with a solid file, while bearing in mind that the final decision rests with the bank.
