Accounting and tax guides

There is no official scale in Belgium: accounting fees are freely set and written into the engagement letter. The ranges observed in 2026 run from roughly 40 to 250 € a month for a self-employed person, and from 2 000 to 5 500 € a year for a small company, depending on the volume of documents and the services included. What drives the bill is not the professional's title but the exact scope of the engagement.

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.
