How Belgium determines residency
Belgium has no statutory day-count for residency — Belgian law sets no 183-day rule. You are tax resident if your domicile (actual residence and centre of personal interests) is in Belgium, or if the seat of your wealth — the place your assets are managed from — is there. Registration in the National Register creates a rebuttable presumption of residency.
For married couples and legal cohabitants, fiscal residence is where the family home is located, regardless of where each spouse spends their days.
