Accounting and tax guides

You can change accountant at any time: no law ties you to a firm, only your engagement letter sets any notice period. In practice, the new firm contacts the previous one to arrange the handover, and the transfer of documents is formalised with an inventory dated and signed by both parties. The best moment remains just after the annual accounts have been filed.

Accountant and tax accountant are professional titles protected by law, governed by the ITAA since 30 September 2020. « Fiduciaire », the common Belgian word for an accounting firm, is not a title: it names a business that employs one or the other of these professionals. The practical difference between the titles concerns the assignments the law reserves for certified professionals, not the quality of routine accounting work.
