ExploreAbout this exam
The ITAA (Institute for Tax Advisors and Accountants) is the Belgian institute that manages the public register of accountants and tax advisors and oversees access to both professions. Its site describes the institute's task as managing that register and supervising entry to the profession by regularly organising admission examinations and competence examinations, while also following each trainee's trajectory between those examinations. The interim exams (tussentijdse proeven) sit inside that trajectory: they are the checkpoints a trainee faces during the three-year stage that the ITAA describes as required, alongside a legally recognised diploma, before obtaining the status of (intern) certified accountant or (intern) certified tax advisor. Candidates are therefore typically graduates who have already passed the admission examination and are now completing their supervised traineeship under a stage mentor, building familiarity with all facets of the profession and with professional ethics. Our practice material is organised around the two professional pillars reflected in the exam profile: accountancy and tax advice, weighted equally. Preparation should combine technical revision of accounting and tax rules with the legal and regulatory framework the ITAA publishes, notably the 2019 law on the professions of accountant and tax advisor and the related royal decrees, plus the institute's examination regulations. Because the ITAA's own interim-exam page was not reachable at the time of retrieval, candidates should confirm practical details such as exam dates, registration periods and formats directly with the ITAA before relying on any schedule. This page is independent study support and is not affiliated with or endorsed by the ITAA.
What you'll study
About ITAA Tussentijdse Proeven preparation
What exactly are the ITAA interim exams?
They are the intermediate assessments a trainee sits during the three-year stage at the ITAA, positioned between the admission examination and the final competence examination. They verify that the trainee is progressing in both accountancy and tax advice before being allowed to continue toward full certification.
Who should take these exams?
Trainees who hold a legally recognised diploma and have entered the ITAA stage, aiming at the title of (intern) certified accountant or (intern) certified tax advisor. If you are still assembling your admission dossier or awaiting exemption decisions, resolve that first; the interim exams belong to the stage trajectory, not to initial access.
How is the exam structured?
The exam profile used here divides content evenly between accountancy and tax advice. The ITAA's own interim-exam page could not be retrieved, so the number of questions, time allowed and exact paper structure are not confirmed on this page. Check the ITAA examination regulations and exam calendar for the authoritative format.
How difficult are the interim exams?
Expect professional-level depth rather than textbook recall: accounting questions tend to require applying standards and norms to a fact pattern, and tax questions require locating the correct rule and computing a consequence. Candidates who only memorise summaries usually struggle with multi-step items and with ethics-related questions.
Can I retake an interim exam if I fail?
The ITAA sets retake rules in its examination regulations, and the source material available here does not state them. Do not assume unlimited attempts or automatic resits. Confirm the position with the ITAA before planning, since a failed interim exam can affect the pace of your stage.
When are the exams held and when do I register?
The ITAA publishes an exam calendar and separate information on exam periods and registrations. Because the interim-exam page was unavailable at retrieval, no dates are given here. Treat registration deadlines as hard deadlines and check the calendar early, since late registration is typically not accommodated.
In what order should I study the two domains?
Build accountancy first: standards, norms and the logic of financial statements underpin many tax computations. Then layer tax advice on top, including procedure and the interaction between accounting profit and taxable base. Finish with professional ethics and the regulatory framework, which are easy to neglect but frequently examined.
What are the most common failure modes?
Three recurrences: skipping the legal framework and ethics because they feel non-technical; practising recognition instead of producing full computations under time pressure; and misreading which regime applies to a fact pattern. Add a fourth: relying on outdated figures instead of the current published rules.
Which official sources should I study from?
The ITAA site links the 17 March 2019 law on the professions of accountant and tax advisor, several 2019 royal decrees on the public register and professional training, and the institute's examination regulations. These, together with the published norms and recommendations, are the authoritative basis for both exam domains.
Is this page an official ITAA resource?
No. This is independent study material written for candidates preparing for the interim exams. It is not affiliated with, endorsed by or connected to the ITAA. Always verify exam dates, fees, formats and retake rules against the ITAA's own publications and service desk before making decisions.
