Do I have to declare my house, plot of land or field abroad to Belgium?
In short
Yes. If you pay taxes in Belgium, you must declare each property abroad separately to the tax authorities. A newly bought property must be declared within 4 months; someone who has just moved to Belgium must declare their existing property within 30 days.
Video transcript
You own a house and a field abroad. Required: If you pay tax in Belgium, each property is declared separately to the tax office. Newly acquired property within 4 months. The right way: Declare every property. Belgium has double tax treaties with many countries, so it is usually about the duty to declare rather than extra tax. If you don't declare: For each plot: 1.000 € – 3.000 € fine; Also: Back taxes; Social assistance: Can be stopped, reclaimed.
What is not allowed, what is required?
- Every property, including houses, flats, plots of land, fields and shops, must be declared separately to the land registry service of the tax authorities.
- A newly bought (or inherited) property must be declared within 4 months; a person who has just settled in Belgium must declare their existing property within 30 days.
- The tax authorities set a cadastral income for each property; you write this income in part III of your tax return every year. If you rent the property out, in some cases you must also declare the actual rent.
- Belgium has double taxation agreements with many countries. If there is an agreement, the issue is usually the duty to declare rather than extra tax.
- If you receive social assistance or live in social housing, you must also declare this property to the organisation concerned.
Penalty and indirect consequences
- Fine / payment
- Not declaring or declaring late: an administrative fine of 1.000 €, 2.000 € or 3.000 €, depending on the cadastral income. The fine applies separately to each plot (legal range 250–3.000 €).
