Legal definition, obligations, differences with the place of business, and practical advantages of professional domiciliation. Complete guide for entrepreneurs in Belgium.
Under Belgian law, the registered office is the official and legal address of a company. It corresponds to the place where the management and administration centre of the company is located. This is the address written into the company's articles of association, published in the Belgian Official Gazette and registered in the Crossroads Bank for Enterprises (CBE).
Legal definition (Belgian CAC)
The registered office is the place where the company's main establishment is located, as mentioned in the articles of association. It determines the nationality of the company and the applicable law.
In practice, the registered office fulfils several essential functions:
Many entrepreneurs confuse these two concepts. Yet they are fundamentally different under Belgian law.
Good to know: An entrepreneur can have their registered office at a domiciliation centre in Brussels and carry out their activity from home or a coworking space. These are two distinct addresses with different functions.
Establishing a registered office in Belgium entails precise legal obligations that every entrepreneur must know.
Every company must declare its registered office to the Crossroads Bank for Enterprises upon incorporation. The address is public and appears on every official company document.
The registered office must appear on your invoices, contracts, website, commercial correspondence, and all official deeds.
The registered office determines the competent court in the event of a dispute, the applicable legislation, and the registration office where deeds must be filed.
The general meeting of partners or shareholders is held by default at the registered office, unless otherwise provided in the articles of association.
Opting for professional domiciliation offers concrete advantages well beyond a simple postal address.
By using a domiciliation address, you avoid publishing your personal address in the Crossroads Bank for Enterprises (CBE) and the Belgian Official Gazette. Your data remains confidential.
An address in a prestigious business district of Brussels, Liège or Antwerp inspires confidence in your clients, partners and investors from the very first contact.
Renting a physical office costs several hundred euros per month. Professional domiciliation offers you all the advantages of a prestigious address from just a few dozen euros.
With a domiciled registered office, you can carry out your activity remotely, while travelling or abroad, with no geographical constraints imposed by your official address.
Your official mail (CBE, tax authorities, court, clients) is received and managed at your registered office address. You are notified immediately, without the risk of missing an important document.
A professional address facilitates the opening of your business account and strengthens your financing file with financial institutions.
The choice of your registered office address is a strategic decision. Here are the essential criteria to consider:
The registered office determines your affiliation with a region (Brussels-Capital, Wallonia or Flanders). Some grants, subsidies and tax exemptions are specific to each region. Analyse the advantages of each region according to your sector of activity.
An address in the centre of Brussels, in a business district or in a prestigious municipality strengthens your credibility. This is particularly important if you regularly deal with clients, banks or investors.
If you do not wish to expose your home address, opt for a professional domiciliation address. It will be your public address in the CBE and on all your official documents.
Choose a provider that offers mail management, digital notification, access to meeting rooms and administrative support. These services will save you time and peace of mind.
Make sure your domiciliation provider is legally authorised to provide this service in Belgium and that your contract complies with the requirements of the CBE and the Companies and Associations Code (CAC).

Reluctant landlord, fear of higher taxes, co-ownership regulations… Here are the concrete obstacles entrepreneurs face when they want to work from home, and how to address them.
Common situation
In Belgium, a landlord can legally prohibit any professional use of a rented property in the lease agreement. Disregarding this exposes you to termination of your lease. This is a real constraint that many entrepreneur tenants face.
The solution
Domicile your registered office at MonSiegeSocial. In most cases, if you do not receive physical clients at your home, you are not required to register a business establishment there. You continue to work from home — which is not prohibited — without any professional address being registered at your home. Your landlord has nothing to object to.
Common misconception
This fear is widespread but largely overstated. Property tax only changes if part of the property is officially designated for exclusive professional use. For an intellectual or service activity carried out at home without specific fittings, the tax impact is generally nil.
The clean solution
Domiciling your registered office at an external professional address eliminates the tax question at the root. If you also do not register a business establishment at your home, no reclassification is possible, no risk of audit related to mixed use of the property, and your home remains purely private in the eyes of the tax authorities.
Legal constraint
Co-ownership regulations are legally binding. If they prohibit commercial activities, registering a business establishment at that address may trigger a complaint from co-owners and a formal notice from the building manager. Ignoring this clause is risky and can lead to legal action.
The solution
External domiciliation clearly separates the legal address (CBE) from your actual place of work. You can work from home without receiving clients or goods there — generally tolerated even in strict co-ownerships — while having an official professional address registered elsewhere.
Unknown risk
Once your private address is registered as a registered office or business establishment, it is accessible to anyone consulting the CBE, and appears on your invoices, website, and all official documents. Bailiffs, canvassers, or any dissatisfied client can knock on your door.
Our recommendation
Domicile from the start. It is much simpler to never expose your private address than to have to remove it afterwards — which requires a costly registered office transfer (notarial deed, Official Gazette, CBE update). For a few dozen euros a month, you permanently protect your privacy.
