Company domiciliation in Luxembourg

A Luxembourg company needs an identifiable registered office. A holding or special-purpose vehicle may not need private premises of its own, but it still needs a stable address for corporate records, official correspondence and legal notices. Domiciliation allows that address to sit with a regulated professional when the activity is compatible with the arrangement.

The service is more than mail forwarding. The consolidated Societies and Associations collection includes the Law of 31 May 1999, which regulates who may provide domiciliation, requires a written agreement and gives the provider continuing duties. The arrangement should therefore be considered at the beginning of company formation and kept aligned with the company’s later activity.

The role of the registered office

The registered office identifies the company under Luxembourg law. It is the address used for corporate filings and formal communications. For a commercial company, the main establishment is presumed to be the registered office unless the facts show otherwise.

The official domiciliation guidance describes domiciliation as a company establishing an office at a third party’s premises and receiving services there. It is suitable where the nature of the activity does not require separate operating premises.

This distinction matters. A SOPARFI holding participations may need a registered office, corporate administration and meeting support without needing a public-facing workplace. A trading, production or retail business normally needs premises that match its operations.

The authorised providers

Professional domiciliation is reserved to specified regulated professions. The official list includes credit institutions, certain professionals in the financial and insurance sectors, Luxembourg avocats à la Cour, European lawyers registered on List IV, company auditors, approved statutory auditors and chartered accountants.

The restriction protects more than the address. These providers are subject to professional standards and oversight. An unregulated office supplier cannot become a domiciliary agent simply by offering a postal address and company services.

The 1999 law also excludes certain arrangements from its domiciliation definition. An office provided within the same parent group, for example, can fall outside the professional domiciliation regime. That exception does not remove the need for a valid registered office or any operational conditions attached to the company’s activity.

The written agreement

The domiciliary agent and the company must enter into a written agreement. It sets the service perimeter, communication process, access to corporate information, responsibilities of each party, duration and termination.

For a regulated financial professional, CSSF rules specify minimum content. Other authorised professions follow their own professional framework. The agreement should match the service actually delivered. A document describing only the use of an address is incomplete when the provider also receives official mail, maintains company records or supports governance.

The company remains responsible for its own corporate, accounting and tax obligations. Domiciliation organises part of the operating framework but does not transfer management responsibility to the provider.

Identity and ongoing information

Before entering the relationship, the domiciliary agent must verify the legal conditions for the registered office and establish the true identity of the members of the company’s governing bodies. The relevant information must be kept current, and identifying documentation must be retained for five years after the agreement ends.

Changes in directors, ownership, beneficial owners or activity can affect the provider’s understanding of the company and its risk. A file that was coherent at incorporation may therefore need updating during the year, not only at the annual accounts date.

Mail handling also requires a clear operating process. Court notices, tax letters and RCS communications can carry deadlines. The agreed route from receipt to the responsible decision-maker should remain reliable even when directors or external advisers change.

Domiciliation and substance

Domiciliation answers where the company has its legal address. It does not by itself answer where material decisions are taken or where the business is operated. Those questions depend on the facts.

A board that understands the transactions, receives useful information and records its decisions supports a different profile from a company whose decisions are made elsewhere and merely signed in Luxembourg. The accounting records, contracts, bank mandates and corporate minutes should describe the same operating reality.

The registered office also cannot replace physical facilities required by the activity. The business-permit conditions require an installation in Luxembourg that is appropriate to the nature and scale of the business. A domiciliation address may fit a holding vehicle but not an activity that needs stock, a workshop or permanent customer access.

The fit across company types

Holdings and acquisition vehicles often use domiciliation because their activity is centred on ownership, financing and governance rather than a large local workforce. An SCSp or its general partner may also need a stable address and coordinated corporate administration.

The analysis changes when the vehicle starts providing services, employing a team or carrying on regulated activity. The registered office can remain with the domiciliary agent, but it may become only one address within a wider Luxembourg operating setup.

Property ownership does not change the basic distinction. An SCI may use domiciliation for its corporate address while the property, leases and related administration remain separate from the registered-office service.

The end of the arrangement

Termination is not complete through a private exchange between the parties. The notice must be filed with the Trade and Companies Register and published in the Electronic Compendium of Companies and Associations.

If the domiciliation address was the registered office, the company loses its legal address from the filing date unless a replacement has already been registered. Official mail, banking reviews and corporate filings can then be disrupted.

The domiciliary agent may revoke the agreement immediately when specified company-law or establishment-law breaches are identified. Continuity is therefore best managed by registering the replacement address before the existing arrangement ends.

Conclusion

Company domiciliation provides a regulated registered office for an activity that does not require separate premises. It depends on an authorised provider, a written agreement and current company information. It supports corporate administration but does not replace effective management, operating premises or the company’s own compliance duties.
