Accounting and tax guides

Starting a business in Belgium comes down to eight steps: choosing between a sole proprietorship and a company, drafting the financial plan, opening the bank account, going to the notary (companies only), registering with the CBE through a business counter, activating VAT, joining a social insurance fund, and then sorting out health insurance, the UBO register and insurance cover. As a sole proprietor, the whole process costs around €200 and fits in a week. For an SRL/BV, budget €1,600 to €3,900 excluding contributions and two to four weeks.

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.
