Verify a licensed pro in 3 steps

Before you hand over documents, confirm the preparer’s credentials against the official source.

Step 1: Search the ITAA public register at itaa.be to confirm that the certified accountant or certified tax professional is currently enrolled and authorised to practice; the register is searchable by name and displays the member's registration status.
Step 2: Ask the practitioner for their ITAA registration number; a currently authorised ITAA member can provide this immediately and it can be cross-checked against the ITAA register to confirm the name, registration category, and active status.
Step 3: For practitioners who describe themselves as company auditors (reviseurs d'entreprises), verify their current authorisation through the IRE/IBR at ibr-ire.be, which publishes a searchable list of authorised statutory auditors in Belgium.
