Do foreign owners of a Belgian company have to file the UBO register?

Yes. If you own a Belgian company, you are legally responsible for filing its beneficial owners in the UBO register, and it makes no difference whether you live in Brussels or on the other side of the world. You registered the company, you thought the paperwork was done, and there is one register most foreign owners have never heard of. Forgetting it can cost up to €50,000.

What catches people is that the obligation does not end at registration. You have to confirm the data at least once a year, even when nothing has changed (verified August 2026).

The UBO register (Ultimate Beneficial Owners) is run by the Belgian FPS Finance, General Administration of the Treasury. It exists under the anti-money-laundering Law of 18 September 2017 (Art. 73 to 75), which transposes EU Directive 2015/849, and the Royal Decree of 30 July 2018. Source: FPS Finance.

What is the UBO register, and why does it apply to you?

The UBO register is a national list of the natural persons who ultimately own or control a company. Every Belgian company has to declare the real people behind its corporate structure, so that authorities can see past the company name.

You are a beneficial owner if you hold more than 25% of the shares, capital, or voting rights of the company, according to FPS Finance. Control can also count through other means, such as the right to appoint directors. And if no single person passes the 25% line, the register falls back to the senior managing official, usually the main director, so a company is never left with nobody to declare.

The obligation covers companies, non-profit associations (ASBL/VZW), foundations, and fiduciaries, and the legal representatives, meaning the directors, are the ones held responsible (FPS Finance). This is the point foreign owners miss most often: the duty attaches to the Belgian entity, not to where its owner lives. A French, American, or Indian owner of a Belgian company is still a UBO of that company and still has to be registered.

The yearly step most foreign owners forget: annual confirmation

Filing your UBO once is not the end of it. Belgian law requires you to confirm the registered data at least once a year, even if nothing has changed, by validating the entry in the register (FPS Finance).

This is a separate duty from updating. If a shareholder changes, you have 30 days to update the register (FPS Finance). But even in a quiet year with no change at all, the annual confirmation still has to happen. It is a small click that is easy to forget precisely because nothing prompts it in your own calendar, and it is the single most common reason an otherwise compliant company slips into breach.

For a solo founder who set the company up once and now just invoices, this is the trap. The company runs fine, the accountant files the VAT, and the UBO confirmation quietly lapses in the background.

What happens if you don't, or you're abroad when the letter arrives?

The sanctions are real and they are aimed at you personally, not an abstract company.

Under Art. 132 of the Law of 18 September 2017, non-compliance with the identification and registration obligations carries an administrative fine of €250 to €50,000, imposed on the legal representatives (FPS Finance; ejustice). On top of that, a separate €500 fine can be imposed jointly on the legal representatives if the UBOs are still not registered after the first reminder (FPS Finance). Prolonged non-compliance can even lead to a strike-off from the Crossroads Bank for Enterprises, which is the register your company legally needs to exist (FPS Finance).

The enforcement step is also what catches absent owners. Before any fine lands, FPS Finance sends a reminder letter to the home address of the legal representative, who then has 30 days to register or ask for a hearing (FPS Finance). If you run your Belgian company from abroad and that letter goes to an address you no longer check, the clock runs out without you ever seeing it. In practice, the owners who get fined are usually not the ones who refused to comply, but the ones who never received the warning.

How do you check and file your UBO in Belgium?

You file online, and it takes minutes once you have the information ready.

Registration is done through the FPS Finance online application by the legal representative or a mandated third party such as your accountant, and you must attach a document proving the registered information is correct (FPS Finance). The three deadlines to hold in mind are simple: within one month (about 30 days) of incorporation for a new company, within 30 days of any change, and the annual confirmation on top (FPS Finance). If you use an accountant, confirm in writing who owns the annual confirmation, because "I assumed my accountant did it" is not a defence the register recognises.

Is your UBO information public in Belgium?

No, not freely. This is worth knowing if privacy is part of why you set up carefully.

After the Court of Justice of the EU judgment of 22 November 2022 (Joined Cases C-37/20 and C-601/20), general public access to UBO registers was struck down. Access is now limited to competent authorities, obliged entities such as banks and notaries, and members of the public who can demonstrate a legitimate interest (FPS Finance access rules). Your ownership is transparent to the state and to regulated professionals, not to anyone who feels like looking.

Where does your registered office fit in?

Your UBO filing and your registered office are two separate things, but they meet at one practical point: the reminder letter goes to the address on file. If your registered office is a real, monitored address, a UBO reminder is opened, scanned, and reaches you in time to act. If it is an address nobody watches, the first you hear of a problem is the fine.

A provider like Yelomex supplies and monitors that registered office and forwards your official mail, which is what keeps a letter like this from turning into a €50,000 surprise. The UBO filing itself stays yours to do, through FPS Finance or your accountant. No address provider files it for you, and any that claims to hide your ownership is describing the exact thing the UBO register was built to stop.

Frequently asked questions

Do I have to file a UBO register if I own my Belgian company from abroad?

Yes. The obligation applies to the Belgian entity regardless of where its owners live. As a foreign owner holding more than 25% of the company, you are a beneficial owner and must be registered, and the company's legal representatives are responsible for filing (FPS Finance).

Do I need to confirm my UBO every year even if nothing changed?

Yes. Belgian law requires an annual confirmation of the UBO data even when there has been no change, in addition to updating within 30 days whenever something does change (FPS Finance).

What is the fine for not registering a UBO in Belgium?

Non-compliance carries an administrative fine of €250 to €50,000 on the legal representatives under Art. 132 of the Law of 18 September 2017, plus a possible €500 fine after a first unanswered reminder, and continued non-compliance can lead to a strike-off from the Crossroads Bank for Enterprises (FPS Finance; ejustice).
