Demystifying Tax Filing for Expats in Belgium: Expert Insights and Strategies

“Expat” is not a tax category, and that is the root of most of the confusion. An EU institution employee, a NATO affiliate, a cross-border worker and someone on assignment are taxed under genuinely different rules. Before anything else, work out which one you are.
At a glance
Which kind of “expat” are you?
Eric Laurent, a partner at the ERYV law firm specialising in international income, has made the point in The Brussels Times that the word covers several groups with little in common for tax purposes:
- EU institution staff, taxed under their own arrangements rather than the Belgian system
- NATO affiliates, similarly distinct
- Cross-border workers, living in one country and working in another
- Assignees, seconded here by a foreign employer
- Ordinary local hires — most of this community — taxed as Belgian residents
Advice aimed at one group can be actively wrong for another, which is worth remembering when reading anything on this subject, including this page.
Establishing residency
Belgian tax residency turns on two tests:
- Domicile — where the centre of your personal and professional life actually is. Note that your tax domicile can differ from your civil domicile; they are not the same concept.
- The seat of your assets — not where the money is held, but from where it is effectively managed.
Registering with your commune makes you a tax resident. Under the Belgian Income Tax Code, entry in the register creates the presumption automatically. It can be rebutted — but the burden is on you to satisfy the tax administration that you do not in fact reside here, and that is an evidential exercise, not a form.
Worldwide income
A Belgian tax resident declares worldwide income, not just what was earned here. For this community that usually means Indian rental income, interest, dividends and capital gains as well as the Belgian salary.
The India–Belgium double taxation treaty exists to stop the same income being taxed twice, but relief is claimed, not automatic — it has to be declared and the treatment argued correctly on the return.
Foreign accounts and property must be declared
Belgian residents report the existence of foreign bank accounts and foreign property, separately from the income they produce. Non-declaration is where people get into trouble — not usually through avoidance, but through not knowing the obligation existed at all. If you have an Indian account, and you almost certainly do, take advice on this specifically.
Before you file
- Check the special tax regime. If you were recruited from abroad on €75,000 or more, it may cut your taxable base by 30% — see the special tax regime. It has a three-month application deadline that runs from your start date.
- Gather the Indian side early. Interest certificates, rental records and capital-gains statements take time to obtain from abroad.
- Keep the payslips. Particularly if you may leave Belgium — the final assessment can arrive a year later, when portal access is long gone.
- Get advice once, properly. A single session with an adviser who handles Indian–Belgian cases in your first year is worth more than several years of guessing, and the fee is generally recovered in what you stop over-declaring.
