Choosing a Belgian accountant: what really matters?

In brief

The choice matters. A good Belgian accountant keeps your figures in order, files your returns and warns you before deadlines. A poor choice costs fines, time and missed opportunities. Here is a simple method to decide without regrets.

Protected titles in Belgium

Since 2019, a single institute has overseen the profession: the ITAA. It merged the former institutes of accountants and bookkeeper-tax advisers. Several titles coexist under its supervision.

• A certified accountant handles accounting and tax work, including some reserved assignments.
• A certified tax adviser specialises in tax advice.
• A certified bookkeeper-tax adviser keeps the books and prepares routine returns.

For a typical SME, all these profiles can keep the books. For more specialised work, check the exact title of your future Belgian accountant.

Statutory audits belong to company auditors

Do not confuse these titles with registered company auditors. Only the latter act as statutory auditors. A large company therefore works with two separate professionals: a Belgian accountant for bookkeeping and advice, and a company auditor for the statutory audit.

Checking the title of your Belgian accountant

The check takes two minutes. The ITAA public register sits on the institute's website. Search by the name of the professional or the firm. Anyone missing from the register may not use the title.

Take the opportunity to check two more points.

• The firm's professional liability insurance.
• The engagement letter, which describes tasks and fees.

Criteria to compare firms

Knowledge of your sector

Each sector has its pitfalls. A Belgian accountant who knows your trade anticipates them.

• Hospitality: registered cash register systems and different rates depending on the service.
• Liberal professions: business expenses and supplementary pension savings.
• E-commerce: distance sales and the OSS one-stop shop.
• Construction: reverse charge and withholdings for social and tax debts.
• Real estate: depreciation and capital gains.

Size of the firm

• A sole practitioner offers a direct relationship, but fragile continuity during absences.
• A small firm combines proximity with cover during absences.
• A large firm brings specialists, often with a less personal relationship.

Services and tools

Beyond bookkeeping, compare the full offer: tax advice, payroll through a social secretariat and support during an audit. Ask your future Belgian accountant which tools the firm uses. An online portal, automatic invoice reading and electronic invoicing save you hours.

Availability

Test responsiveness before you sign. Send a precise question by email and measure the response time. A firm that needs a week to reply before signing rarely answers faster afterwards. Your Belgian accountant should reply within days, not weeks.

Fees: how a Belgian accountant charges

Three models dominate.

• A monthly or annual flat fee, for a defined set of tasks.
• An hourly rate, common for one-off advice.
• A price per service, for example per return or per year-end closing.

A flat fee gives a small business visibility. Still, check what it covers: number of documents, returns, meetings and questions. Extra charges often make the difference between two quotes.

The cheapest option does not always win. Imagine a firm that costs 1,500 euros more per year. If it spots a missed deduction that cuts your tax by 4,000 euros, the maths clearly favours it.

Questions for the first meeting

These questions help you pick a Belgian accountant with confidence.

Warning signs

Be careful in the following situations.

• The professional does not appear in the ITAA register.
• The firm refuses to provide a written engagement letter.
• Your returns go in late, again and again.
• You never receive advice unless you ask for it.
• The firm cannot show professional liability insurance.

A serious firm will also ask for your identity card and information on beneficial owners. These questions stem from anti-money laundering law. They signal diligence, not distrust.

Switching to a new Belgian accountant

You can change firms, ideally after a financial year end. Respect the notice period in the engagement letter. The new professional normally contacts the predecessor to organise the handover. Then revoke the old access mandates to your online tax files and grant new ones.

In short

A good Belgian accountant combines a verified title, knowledge of your sector and real availability. Check ITAA registration, compare flat fees in detail and ask your questions before signing.
