Key takeaways
- A missed filing, update, or annual confirmation with the UBO register exposes directors and managers to an administrative fine under the law of 18 September 2017.
- The fine targets the legal representatives responsible for the filing personally, not the company as a legal person.
- The Administration générale de la Trésorerie, part of the Federal Public Service Finance, oversees the register and in practice sends a reminder before sanctioning.
- Beyond the fine, missing or inconsistent UBO data can delay opening a business bank account or signing a notarial deed.
A skipped annual confirmation, an initial filing that was never made, data left outdated after a change of shareholder: UBO register penalties in Belgium catch out directors every year who had nothing to hide, just a formality that fell off their radar. Since the law of 18 September 2017 on preventing money laundering and terrorist financing took effect, the beneficial owners register is no longer a box ticked once at incorporation: it is a live obligation, monitored, and subject to administrative sanction on breach. This article details what a defaulting director or manager actually risks, how the sanction procedure unfolds, and how to avoid getting there.
Which breaches are sanctioned
The UBO register rests on three distinct duties, and each one can give rise to a sanctionable breach: the initial filing of beneficial owners when the entity is set up, an update within one month of any change affecting that information, and an annual confirmation that the recorded data remains accurate even when nothing has changed. A substantive breach can also arise, one less often spotted at first glance: incomplete or inaccurate information, for example a wrong ownership percentage or an omitted beneficial owner.
The annual confirmation is, in practice, the most common breach. Many directors consider their file closed after the initial filing and are unaware that a confirmation is owed every year, even when nothing has changed since the last filing. This point is covered in detail in our reference article on the UBO register.
The amount of the administrative fines
The law of 18 September 2017 provides for an administrative fine in the event of a breach of UBO register duties (art. 132, § 6, of the law of 18 September 2017). The administration has discretion to set the amount within the legal range, based on the severity and repetition of the breach found.

How the sanction procedure unfolds
The UBO register is managed by the Administration générale de la Trésorerie, part of the Federal Public Service Finance (art. 73 of the law of 18 September 2017), which is also the authority competent to find breaches and impose the fine. In practice, a control check does not immediately lead to a financial sanction.
- 1
Breach detected
Control checkThe administration identifies a missing, outdated, or inconsistent filing, either by cross-checking its own data or from a report by an obliged entity (bank, notary, accountant).
- 2
Reminder or formal notice
Correction periodA letter invites the legal representative to correct the situation within a given period, by completing or correcting the filing on the Federal Public Service Finance's dedicated application.
- 3
Correction
On the director's actionThe corrected filing ends the breach. In the large majority of recorded cases, a correction made within the given period avoids the financial sanction.
- 4
Administrative fine
If not correctedIf the situation is not corrected within the period, the administration may impose the fine, with the amount set within the legal range based on the severity and repetition of the breach.
This practice of a reminder before a sanction never removes the legal duty itself: the breach exists as soon as the filing or update deadline is missed, whether or not the administration has already detected it.
Beyond the fine: the practical consequences
The administrative fine is not the only risk tied to a UBO register in default. The law of 18 September 2017 requires entities subject to anti-money-laundering law, chiefly banks, notaries, and accountants, to check that the information they hold on a client matches the UBO register, and to electronically report any discrepancy they find to the administration (art. 74/1, § 1, of the law of 18 September 2017).
| UBO register up to date | UBO register in default | |
|---|---|---|
| Opening a business bank account | Standard processing | Delayed until corrected |
| Notarial act (deed, mortgage) | Standard processing | Extra checks, longer delay |
| Risk of administrative fine | ||
| Possible report by an obliged third party |
In practice, a bank that finds a discrepancy between its own information and the UBO register can suspend opening an account or ask for further supporting documents before continuing the relationship. A notary facing the same situation during a deed (a property sale by the company, a mortgage) can likewise delay signing. These blockages, purely operational, often reach the director before a fine is ever mentioned.
How to avoid UBO register penalties
Most sanctioned files do not stem from an intent to conceal, but from a plain oversight, particularly for the annual confirmation. A structured tracking of these deadlines avoids nearly all at-risk situations.
To stay compliant with the UBO register
Check that the initial filing was actually made at incorporation
Within one month of the entity, the company or the ASBL, acquiring legal personality.
Update the filing within one month of any change
A new shareholder, a change in a shareholding, a change of manager or director.
Add the annual confirmation to the governance calendar
Handle it alongside the general meeting or the filing of annual accounts, so it is not forgotten.
React immediately to any reminder from the administration
A quick correction, before the given period expires, is the most effective lever to avoid the fine.
Hand the tracking to a provider if internal governance is limited
A payroll office or a registered-office provider that builds deadline tracking into its service sharply cuts the risk of an oversight.
A company with a registered-office provider that builds legal-deadline tracking into its offering avoids this kind of oversight structurally, the same principle that applies to filing annual accounts applying equally to the UBO confirmation.
