Moving from Belgium Tax Guide 2026: No Exit Tax, Commune Deregistration & Belgian Pension

KEY INSIGHT

Belgium has no exit tax — there is no deemed disposal of assets when you leave. The key administrative step is deregistering from your commune's National Register (Registre National / Rijksregister), which confirms your departure date for Belgian tax purposes. The Belgian special expatriate tax regime (for qualifying foreign executives) ends on departure. Belgian-source income (property income, dividends from Belgian companies) remains taxable in Belgium as non-resident via Taxe des Non-Résidents (TNR). Belgian state pension is fully portable internationally.

Key Facts

No Belgian Exit Tax: Clean Departure

Belgium does not have a general exit tax on individuals departing. There is no deemed disposal of investment portfolios, shares in Belgian or foreign companies, real estate, or other assets when you permanently leave Belgium. This means: departing Belgium residents with large investment portfolios face no immediate Belgian tax event on departure. The distinction from France (impôt de sortie) is significant — Belgian investment portfolios can be transferred abroad without any Belgian CGT consequence. Belgium does have a Taxe sur les Comptes-Titres (Securities Accounts Tax, TCT) — an annual 0.15% tax on securities accounts above €1,000,000 held by Belgian residents. On departure: this TCT ceases to apply (non-residents are no longer subject to it). Capital gains on shares: Belgium generally does not tax capital gains on shares for individuals (there is no Belgian CGT on shares, except for speculative gains — treated as taxable income). Dividends: Belgian withholding (précompte mobilier / roerende voorheffing) at 30% applies to Belgian-source dividends — this continues as a non-resident (the withholding is the final Belgian tax on dividends). Belgian real estate: if you retain Belgian property, rental income is taxable (see below). No Belgian CGT on property gains for private individuals (the general rule — though specific anti-avoidance provisions apply for quick sales).

Commune Deregistration from the National Register

Belgium's population is registered in the Registre National des Personnes Physiques (National Register) / Rijksregister, maintained at the level of each commune (municipality). When leaving Belgium permanently: visit your commune's Administration communale (gemeenteadministratie) and declare your departure. You will be 'radiation' (cancelled from) the national register. The commune deregistration date becomes your official Belgian residency cessation date for Belgian tax purposes. Documentation: bring your identity documents and proof of destination (rental agreement, employment contract abroad, or similar). Belgian eID (electronic identity card): surrender or retain — it technically expires, but the eID number is not revoked. Your Belgian national number (numéro national / rijksregisternummer) remains permanently assigned to you — useful for Belgian pension, property matters, and any future Belgian tax obligations. Belgian tax reference number (BEL tax ID): retained permanently. SPF Finances (Belgian tax authority): is automatically notified via the commune system when you deregister. Your Belgian tax dossier is transferred to the non-resident taxation unit.

Belgian Special Tax Status for Expatriates: End on Departure

Belgium's special tax status for expatriate executives and specialists (régime spécial d'imposition / bijzonder belastingregime) — reformed significantly in 2022 — allows qualifying foreign professionals working in Belgium to treat Belgium as a 'place of activity' (not domicile), excluding certain costs from Belgian taxable income. The reformed 2022 regime: offers a 30% flat expense allowance (up to €90,000/year) for qualifying foreign employees assigned to or recruited in Belgium, valid for maximum 5 years. When you leave Belgium: the special status ends immediately. There is no clawback of the tax benefits received during the special status period. Your Belgian employer should update payroll from your last day of Belgian employment. The special status is not available in the year after departure — it is a Belgium-specific relief tied to Belgian employment and residency. Non-Belgian nationals who entered Belgium under this regime should verify with their HR that all social security obligations are correctly settled on departure.

Belgian Pension (Pensie/Pension) and Social Security Abroad

Belgium's statutory pension system (régime légal de pension / wettelijk pensioenregime) is administered by the ONSS/RSZ (Office National de Sécurité Sociale) for contributions and ONPFA/PDOS (Office National des Pensions) for payments. Belgian state pension: fully portable internationally. Payable from age 65 (standard; Belgium is moving toward 67 by 2030). The pension is based on lifetime Belgian earnings and contributions. Contact ONP (Pension.fgov.be) before departure to: (1) request your pension statement (relevé de carrière / loopbaanoverzicht); (2) register your overseas payment details. International payments: ONP pays internationally by bank transfer. Annual 'life certificate' (certificat de vie / levensbewijs) required — can be obtained at your local authority abroad. Belgian pension withholding: Belgium withholds précompte professionnel on pension income for non-residents. Under most DTAs, the country of residence has primary taxing rights on pensions — Belgian withholding is creditable. Complementary pension (2nd pillar, pension complémentaire): occupational pension plans regulated by the WAP/LPC law — benefits are preserved on departure. Contact your plan administrator or assureur (insurance company) for non-resident payout arrangements. Second pillar pension is generally payable from age 60 (or at retirement age). Belgian social security contributions (cotisations ONSS): cease when Belgian employment ends.

Final Belgian IPP/PB Return and Non-Resident Property Tax

Final Belgian income tax return: Belgium's personal income tax is called IPP (Impôt des Personnes Physiques) / PB (Personenbelasting). File your final IPP/PB return for the year of departure via Tax-on-Web (finances.belgium.be). Belgian tax year = calendar year (January–December); return deadline is June 30 (online). The return covers January 1 to your departure date for Belgian-source income, plus worldwide income for the period of Belgian residency. Commune surcharge (centimes additionnels / opcentiemen): Belgian income tax includes a commune surcharge (typically 6–8% of the federal income tax) — this applies for the period of commune residency in the departure year. Non-resident taxe communale des non-résidents (TCR): non-residents with Belgian-source income who no longer have the commune surcharge system still pay a non-resident commune surcharge via the TCR — a 7% surcharge on non-resident Belgian-source income. Belgian property: if you own Belgian real estate as a non-resident, you pay: (1) Précompte immobilier (PRI) — annual property tax based on the revenu cadastral (cadastral value); (2) income tax on rental income — non-residents declare Belgian real estate income on the non-resident return (Taxe des Non-Résidents / Belasting der Niet-Inwoners). File annually via Tax-on-Web. Capital gains on Belgian property: generally exempt for private individuals — Belgium has no CGT on private property gains (with exceptions for 'speculative' disposals).

Introduction

Belgium is home to one of Europe's largest expat communities — Brussels hosts EU institutions, NATO headquarters, and dozens of multinational headquarters, creating large inflows and outflows of international professionals. Belgium's departure rules are relatively straightforward — no exit tax, a clear deregistration process, and a well-established non-resident withholding framework. However, Belgium's unusual commune-level tax surcharges, the expat special status regime, and the complex Belgian property tax system create specific considerations for departing residents.

Moving from Belgium to the USA: Key Planning Points

Belgium-to-USA migration is common among NATO/EU institution employees, multinational executives, and Belgian nationals. Key BE-US planning points:

US-Belgium DTA: The 2006 Belgium-USA DTA is comprehensive. Belgian dividends: 15% Belgian withholding (5% for qualifying companies); creditable on US return. Belgian pensions: generally taxable in the USA under the DTA; Belgian withholding credited. Belgian real estate: Belgium retains taxing rights; US taxes worldwide income with FTC. The DTA has a saving clause for US citizens.

Belgian dividend withholding (précompte mobilier) on VVPRbis shares: Belgium has a reduced 15% dividend withholding rate for small company dividends on 'VVPRbis' shares (Vennootschappen/Sociétés — shares issued since July 2013 in exchange for new cash contributions to small companies). If you hold VVPRbis shares in a Belgian BVBA/SPRL, the 15% withholding rate is preserved as a non-resident — advantageous if your destination country's DTA rate is higher.

Belgian bank accounts: Maintain for ongoing Belgian income (property, pension). Belgium participates in CRS — your account details are reported to your new country's tax authority. US FBAR: Belgian accounts over $10,000 must be reported annually once you are a US resident.

FAQ

Frequently Asked Questions

How do I formally deregister from Belgium for tax purposes?

The deregistration process: (1) Go to your commune (town hall, maison communale / gemeentehuis) in person with your ID card. (2) Declare your intention to move abroad permanently (radiation du registre des étrangers or Belgians: radiation du registre de la population / afschrijving uit het bevolkingsregister). (3) Provide proof of your departure address abroad (rental contract, employment contract, or a declaration). (4) Receive confirmation of your deregistration date. This automatically notifies SPF Finances (Belgian tax authority) via the National Register. From this date, you are an official non-resident of Belgium. You will receive your final Belgian tax assessment for the year of departure in due course. Keep your Belgian national register number and any Belgian tax reference numbers — you will need them for property tax, pension, and any non-resident Belgian tax filings.

I own a Belgian apartment — what are my tax obligations as a non-resident?

Belgian property as a non-resident: (1) Précompte immobilier (PRI) / Onroerende voorheffing: annual property tax — billed by the Belgian regional tax authority (Brussels, Wallonia, or Flanders) based on the revenu cadastral. Amounts vary by region; typically paid in August/September. Set up bank domiciliation (direct debit) to avoid missed payments while abroad. (2) Income tax on Belgian real estate: as a non-resident, you declare Belgian real estate on the Taxe des Non-Résidents return. For Belgian property that is NOT rented: you declare the revenu cadastral indexed and increased by 40% — taxed at progressive rates minus the non-resident commune surcharge (7%). For Belgian property that IS rented to individuals: declare the revenu cadastral (not the actual rents) — same calculation. For rented to companies: declare actual rents net of 40% deduction. (3) VAT on rental: if you rent to a company and the rental is subject to Belgian VAT (optional for commercial property from 2019), register with the Belgian VAT system. (4) Capital gains on eventual sale: generally no Belgian CGT for private individuals on residential property held for personal use — clean sale.

I was on the Belgian special expat status — do I owe anything on departure?

No — there is no clawback of the Belgian special expat status benefits on departure. The 30% expense allowance (up to €90,000/year) and cost-of-living exclusions received during your Belgian assignment are not reclaimed when you leave. Your final Belgian salary is subject to normal Belgian withholding for the non-special-status portion (if you depart mid-year after the regime ends, or simply your last salary). The special status is employer-administered — your employer's payroll department handles the termination of the regime in their payroll system. You do not need to notify SPF Finances directly about the expat status ending — it is tied to your employment and Belgian residency. Your final IPP/PB return reflects the special status for the eligible period and normal Belgian tax for the departure period after the regime ends (if applicable — for most, the regime ends with employment, which ends on the same day).

What happens to my Belgian complementary pension (2nd pillar) when I move abroad?

Belgian occupational pension plans (pension complémentaire / aanvullend pensioen) are regulated by the WAP/LPC (Wet/Loi sur les Pensions Complémentaires). Your accrued second pillar benefits are fully vested after 3 years of plan participation (since the 2019 reform, vesting is from day 1 for contributions). Options: (1) Leave in Belgium: your benefits remain with your plan's assureur (insurance company or pension fund) and are payable at retirement age (typically 60 or 65, depending on plan terms). Contact the plan administrator for your individual benefit statement (fiche de pension). (2) Transfer: internal transfers within Belgium are possible; cross-border transfers outside the EU are generally not possible for Belgian second pillar plans. Taxation of Belgian second pillar on retirement: lump sum paid internationally subject to Belgian withholding (typically 10% for 'bonus' contributions; lower rates for employer contributions depending on the regime). The ONP pension simulator (pension.fgov.be) covers both first and second pillar.

Belgian IPP/PB rates, commune surcharges, second pillar pension rules, and TCR procedures change with Belgian federal and regional tax legislation.
