Frequently asked questions
Which 32 categories of entities are subject to the Belgian Act of 18 September 2017?
The Belgian Act of 18 September 2017 subjects to its obligations: credit institutions, banks, life insurance undertakings, investment firms, currency exchange offices, notaries, bailiffs, lawyers (for certain activities), statutory auditors, accountants, tax advisers, real-estate agents, company service providers (including domiciliation centers), casinos, dealers in precious metals and works of art above 10,000 euros, and since the 5th Directive, crypto-asset platforms. In total, 32 categories are covered regardless of the size of the structure.
What is the maximum administrative fine under the Belgian Act of 18 September 2017?
For a legal person, the maximum administrative fine is 5,000,000 euros or 10% of annual turnover, whichever is higher. For a director or compliance officer personally, the fine can also reach 5,000,000 euros. These sanctions are imposed by the competent supervisor: SPF Economie for non-financial professions, NBB or FSMA for the financial sector. Sanctions may also be published on the supervisor's website, causing major reputational damage.
What is enhanced due diligence and when is it mandatory in Belgium?
Enhanced due diligence (EDD) consists of applying more in-depth identification and verification measures than the standard process. In Belgium it is mandatory in four main cases: the client is a politically exposed person (PEP) or a close associate of a PEP; the client is domiciled in a high-risk third country identified by the European Commission; the transaction is unusual or complex without clear economic justification; the relationship is established remotely without using a substantial-level electronic identification system. Concrete measures include senior management approval, verification of the source of funds, and increased review frequency.
How does the Act of 18 September 2017 relate to European AML directives?
The Belgian Act of 18 September 2017 transposes the 4th EU Directive (EU 2015/849) and has been supplemented to integrate the 5th Directive (EU 2018/843) on crypto-assets and public access to the UBO register, and the 6th Directive (EU 2018/1673) on harmonisation of criminal penalties. The 2024 European regulatory package (AMLA, AML-R) will further strengthen the framework from 2026-2027, making certain rules directly applicable without national transposition.
