Leaving Belgium: the questions people actually ask

Yes. Under an agreed review engagement, our team reviews your residency file and supporting package, provides a written advisory opinion and recommends revisions. That is our opinion — not an FPS Finance determination or an advance ruling.

No. Belgium has no residency-opinion request and no residency certificate for leavers. Residency is decided on the facts — domicile, or seat of wealth — with a rebuttable presumption for anyone in the National Register. If you want binding certainty on a specific structured question, the Service for Advance Decisions can issue a ruling. FPS Finance guidance ↗

There is no general exit tax on a person leaving Belgium, and none on real estate. But since 1 January 2026 the tax on capital gains on financial assets (Law of 6 April 2026) treats your financial assets as disposed of when you cease to be resident. Moving to an EEA state or a treaty country with exchange of information gives an automatic deferral; elsewhere you request deferral and give a guarantee. If you do not sell within 24 months the tax is cancelled definitively. Separately, since 29 July 2025 a Belgian company that emigrates triggers a deemed dividend for its shareholders.

Not automatically. Deregistration removes the National Register presumption, but the test is still where your domicile or the seat of your wealth actually is. For married couples and legal cohabitants the domicile is where the household is established — if your partner stays in the family home in Belgium, FPS Finance treats both of you as resident.

You keep paying the regional property tax (précompte immobilier / onroerende voorheffing) as before. If you let it out and your total income from Belgian immovable property is 2,500 euro or more, you must also file the non-resident income tax return; below that, with no other Belgian income, there is nothing to file. A home you keep available to yourself is also a residency fact and needs to be explained in the file. Non-resident return ↗

Belgian pensions for employees, civil servants and the self-employed are paid abroad by the Federal Pensions Service; you must notify it of your new address in writing and return a certificate of life each year. Your mutuality cover follows Belgian social security status — within the EU/EEA the coordination rules apply, in some countries a bilateral agreement, and outside Europe you can join Overseas Social Security. Belgian pensions and Belgian professional income remain reportable in the non-resident return. Your Belgian pension abroad ↗

No blanket rule requires it. Accounts are one element of the seat-of-wealth analysis, alongside your home, your household and where your economic life runs. Keep what you need, put it on non-resident status, disclose it, and be able to explain it.

Re-registering in a Belgian commune restores the presumption of residency, so a short absence followed by a return invites the question whether you ever left. Under the 2026 capital gains rule, returning within the 24-month window without having sold cancels the deferred exit tax. Keep the departure file: it is the same evidence you will need to show the gap was real.
