Can I use a virtual office as my registered office (siège social) in Belgium?

When setting up a company in Belgium, one of the first practical questions is whether you can use a virtual office address as your registered office. The answer is yes, but understanding how it works legally will save you time and prevent unnecessary complications later.

What a registered office ?

Under Belgian company law, the registered office (siège social) is the official legal address of your company. It is recorded in the articles of association and registered with the Crossroads Bank for Enterprises (Banque-Carrefour des Entreprises, BCE), the central database of Belgian businesses.

This address serves several concrete functions: it determines which Belgian court has jurisdiction over disputes involving your company, it is where official correspondence from the tax authorities (SPF Finances) and other public bodies is sent, and it is the address banks and notaries refer to when verifying your company's registration.

Belgian law also distinguishes between the registered office and the business unit address (unité d'établissement), the place where your actual activity takes place. These can be different addresses. For companies that operate remotely, from client sites, or across multiple locations, the registered office and the business unit address often do not coincide. This distinction is what makes business domiciliation a legally recognised and practical solution.

The legal framework for business domiciliation in Belgium

Virtual offices are formally regulated. Any organisation offering domiciliation services must be registered with the SPF Économie, specifically with the Directorate-General for SME Policy. This requirement came into force on September 18, 2017, as part of Belgium's anti-money laundering and counter-terrorism financing framework.

To obtain this registration, a domiciliation provider must be registered with the BCE, hold a valid lease or title for the premises, maintain physical infrastructure (furnished offices, secure document storage, IT equipment, a reception area), carry professional liability insurance, and apply full KYC and AML due diligence to its clients.

When you sign a domiciliation contract with a registered provider, you are contracting with an organisation that has been formally authorised by the Belgian state. That contract serves as legal proof that your registered office address is legitimately secured, and your notary will request a copy of it as part of the incorporation process.

What This Means in Practice

A registered office address provided by an accredited business domiciliation provider carries full legal validity. It appears in the BCE with the same status as any other registered office, the SPF Finances recognises it for tax purposes, banks accept it for business account opening and courts recognise it for jurisdictional purposes. The Belgian administration does not distinguish between a traditional office and a domiciliation address in terms of legal validity. What matters is that the address is real, that the provider is accredited, and that the relationship is formalised in a written contract.

One common concern is whether banks will accept a virtual office address. In practice, Belgian banks regularly accept domiciliation addresses for business account opening, provided the company presents a valid BCE registration certificate and a copy of the domiciliation contract. The accreditation of the provider is the deciding factor.

Another concern relates to tax authorities. The SPF Économie accreditation requirement exists precisely to ensure that domiciliation addresses meet the standards expected by the tax administration. An address provided by an accredited provider is recognised as a legitimate registered office, with no additional scrutiny attached to it simply because it is a domiciliation address.

Changing your registered office later is also straightforward. For an SRL, the process involves amending the articles of association, publishing the change in the Belgian Official Gazette, and updating the BCE. The associated cost is €207.76.

Why a postal code 1000 address

Choosing Brussels for your registered office has practical implications beyond prestige. Brussels 1000 is where the BCE's central administrative services are based, along with the SPF Finances offices, the Brussels Commercial Court, and a concentration of notaries and legal professionals who handle company incorporations regularly. Official correspondence reaches these institutions reliably and quickly.

Brussels is also the de facto capital of the European Union, which matters for companies working with EU institutions, seeking international partnerships, or navigating cross-border regulatory requirements.

Yelomex is located in Brussels, postal code 1000.
