Moving abroad — Dienst Bevolking van de gemeente · Belgium

Direct answer

Deregister from the population register at Dienst Bevolking van de gemeente / Mijn Burgerprofiel (belgium.be) in the days before or after you leave — it ends your municipal obligations and starts your emigration for tax and social security. Then FOD Financiën — bezwaar / MyMinfin (02 572 57 57): a final tax return, your new address, and whether you stay taxable on income from Belgium. RVA / RSZ / mutualiteit — ombudsdienst (rva.be): what happens to your pension rights, health insurance and any benefits, and the forms to take (S1, U1, A1, pension statements). Keep your digital ID active if the country allows non-residents to use it — it makes everything from abroad easier.

❓ Frequently asked

Can I keep my health insurance?

Usually not once you no longer live in the country, unless you are posted by an employer (A1). Pensioners moving within the EU get the S1 form.

Will I lose my pension years?

No — EU coordination adds them up and each country pays its share when you retire. Keep every statement.

I might come back

Nothing prevents re-registering. Do not keep a fake registration "just in case" — it creates tax and benefit problems.
