Belgian expats in Spain face one of Europe's more complex cross-border inheritance tax positions: Belgium operates three separate regional inheritance tax regimes (Flemish, Walloon, Brussels-Capital) mirroring Spain's own regional structure — but with no bilateral IHT treaty between Belgium and Spain. Only Spanish Article 23 unilateral credit operates. Belgian réserve héréditaire, civil-law succession, and Brussels IV election navigate cross-border estate planning. We coordinate both sides carefully.
Belgium operates an unusually complex inheritance tax system. Inheritance tax (droits de succession/erfbelasting/Erbschaftssteuer — the three language versions) is regionalised across the Flemish Region, Walloon Region, and Brussels-Capital Region. Each has its own rate schedules, allowances, and rules. The applicable region is determined by the deceased's fiscal domicile (habitual residence for Belgian inheritance tax) in the 5 years before death — the 5-year preponderance rule.
Rate ranges broadly: direct line (spouse, children, parents) 3–27% Flemish, 3–30% Walloon, 3–30% Brussels; siblings 20–55% Flemish and 20–65% elsewhere; distant relatives and unrelated up to 80% in Walloon/Brussels regions. Spouse has specific exemptions and allowances varying by region. The rates are among the highest in Europe at the higher brackets.
Belgium has no bilateral IHT treaty with Spain. Only Spain's Article 23 unilateral credit applies on Spanish-situated assets. This puts Belgian expats in the same unilateral-credit-only position as British, American, Canadian, Australian, Dutch expats — unlike German, French, Danish, Swedish expats who have or had treaty coordination.
Belgian succession law under the Code civil / Burgerlijk Wetboek preserves a strong réserve héréditaire for descendants (half of estate with one child, two-thirds with two children, three-quarters with three or more — since 2018 reform). Spouse has right to usufruit/vruchtgebruik on the family home. Brussels IV election of Belgian law preserves this civil-law structure across Spanish assets; alternatively election of Spanish habitual-residence law switches to Spanish legítima.
This page covers Belgian regional droits de succession, Brussels IV election, réserve héréditaire vs legítima, Belgian property and pension retained, and dual-will architecture. If you are a Belgian citizen in Spain or a Belgian resident with Spanish property, open a file with us.
Six rules govern every Belgian-connected Spanish estate. Start here.
Flemish, Walloon, Brussels-Capital — each with its own rates and allowances. Applicable region determined by deceased's habitual residence in 5 years before death.
Three regions, one taxUnlike Germany/France/Denmark, no bilateral IHT treaty. Only Spanish Article 23 unilateral credit on Spanish-situated assets. Belgian side operates independently.
Unilateral credit onlyDescendants' réserve: ½ with one child, ⅔ with two, ¾ with three+. 2018 reform capped at ½ of estate total for descendants combined. Spouse usufruit on family home.
Post-2018 reformBelgian testators elect Belgian civil law on Spanish wills under EU 650/2012. Preserves Belgian réserve — or elect habitual residence law to switch to Spanish legítima.
Belgian law electionDirect line 3–30% depending on region and band. Siblings 20–55%/65%. Distant up to 80% Walloon/Brussels. Spouse allowances and family home exemptions regional.
Regional rate variation2018 reform introduced pacte successoral (global or ponctuel) — family agreements binding on signatories. Can structure Spanish-Belgian cross-border settlements under Belgian law.
Post-2018 instrumentBelgian droits de succession applicable regime depends on the deceased's fiscal domicile in the 5 years before death (5-year preponderance rule). If the deceased had their fiscal domicile in the Flemish Region for most of the 5 years, Flemish rates apply. Walloon most — Walloon. Brussels most — Brussels-Capital.
Flemish Region: direct line (spouse, children, parents) 3% up to €50k, 9% €50k–€250k, 27% above. Favourable allowances including family home exemption for spouse/cohabitant. Siblings 25% up to €75k, 30% to €125k, 55% above. Other 45% up to €75k, 55% to €125k, 65% above.
Walloon Region: direct line 3% up to €12.5k, up to 30% top bracket. Higher rates than Flemish at the top. Siblings 20–65%. Other 30–80%. Spouse benefits from family home exemption on part of value.
Brussels-Capital Region: similar to Walloon but with specific allowances. Direct line up to 30%. Siblings 20–65%. Other 40–80%. Family home exemption for spouse/cohabitant.
For Belgian expats in Spain who were Belgian-resident in the 5 years before death, the regional regime they spent most time in applies. For Belgian expats who have been Spanish-resident for >5 years, Belgian fiscal domicile has typically ceased — no Belgian regional regime applies, only the federal death duty on Belgian-situated property (if any).
Belgian tax residence for income tax requires habitual residence, family seat, or centre of economic interests in Belgium. Emigration ends residence: sale of Belgian home, family relocation abroad, centre of life shift. For Belgian inheritance tax specifically, the 5-year lookback rule catches Belgian expats dying within 5 years of departure — their regional regime applies to the whole worldwide estate.
For a Belgian retiree moving to Spain in January 2024: die before January 2029 — Belgian regional regime applies to worldwide estate. Die after January 2029 — Belgian droits de succession only on Belgian-situated assets (real property). Material planning around the 5-year mark.
Since 2018 Belgian inheritance law reform, the descendants' total réserve is capped at half of the estate, regardless of number of children. Previously: ½ with one child, ⅔ with two, ¾ with three or more — could leave as little as ¼ disposable. Post-2018: always ½ réserve total and ½ disposable (quotité disponible), giving testators much wider freedom with larger families.
Spouse reserve: usufruit on at least family home and household goods, plus half-usufruit on estate remainder if children present (more if no children). The spousal usufruit regime is a distinctive feature of Belgian civil law, differing from outright-share systems in most other jurisdictions.
Under Brussels IV election of Belgian law, réserve and usufruit govern the Spanish estate. Spanish legítima displaced. The usufruit structure on Spanish property works in practice: Spanish notaries recognise usufructo (the Spanish analogue) and Land Registry records the divided property between bare owner and usufruct holder.
Each Belgian region has a family home (gezinswoning/habitation familiale) exemption for the surviving spouse or registered cohabitant. Flemish: 100% exemption on the family home for spouse/legal cohabitant. Walloon: similar exemption with conditions. Brussels: up to €250k exempt. This is the single largest Belgian regional planning instrument for couples.
For Belgian expats relocating to Spain, the Belgian family home exemption continues to apply if the property remains the family home (occupied by the couple before death). An emigrated Belgian family that has let out or sold the Belgian home may lose the exemption; care needed on emigration mechanics to preserve.
Belgian pensions and life insurance have specific death transfer rules. Assurance-vie (tak 21, tak 23 products) typically pay to named beneficiaries outside the estate for civil succession purposes, but inside the droits de succession base for tax purposes (specific rules). Belgian pension payouts to beneficiaries generally fall within droits de succession if Belgian-taxed.
For Spanish-resident Belgian beneficiaries, Spanish IHT applies to received death benefits with regional bonificación. No treaty credit — only Article 23 unilateral credit to the extent applicable.
We determine your applicable Belgian region, map the 5-year lookback window, and identify when your Spanish residence falls cleanly out of the Belgian net.
We draft coordinated Belgian and Spanish wills with Brussels IV Belgian-law election, preserving réserve héréditaire and spousal usufruit over the Spanish estate.
We leverage Belgian Flemish Region low rates, family home exemption, and bankgift timing alongside Spanish regional bonificación — both regional systems working together.
On bereavement we run Belgian notaris/notaire estate procedures, Belgian regional droits de succession filing (within 4 months of death in Flemish Region, varied in others), Spanish IHT Modelo 650, and dual property registrations.
The 2018 Belgian inheritance law reform introduced the pacte successoral (global or ponctuel) — a family agreement on inheritance matters that binds the signatories. Global pacts address the whole estate balance between children; ponctuel pacts address specific assets or gifts. They require notarial form and broad family consent.
For Belgian expats with Spanish assets, a pacte successoral under Belgian law can bind the family to an agreed distribution including Spanish real property. Brussels IV election of Belgian law on Spanish wills coordinates with the pacte. This is one of the few civil-law systems that has introduced binding family succession agreements — a useful planning tool for complex blended-family situations.
Belgian gift tax (droits de donation) operates regionally alongside droits de succession. For registered gifts at Belgian notary: direct line 3% (movables) or 3/9/18/27% banded (immovables) at Flemish rates; Walloon 3–30%; Brussels 3–30%. Unregistered informal gifts of movables attract no Belgian tax — but if the donor dies within 3 years (Flemish) or 5 years (Walloon/Brussels) of the gift, the value comes back into the inheritance tax base.
Belgian gift planning strategy for Spanish-resident children: register at Belgian notary for Flemish Region direct line 3% on movables — very low rate. Spanish gift tax side applies on the Spanish-resident recipient's region with full regional bonificación available. Exceptionally efficient for substantial lifetime wealth transfer.
A different route: unregistered informal gift (bankgift through account transfer), survive the 3/5-year lookback, then out of Belgian tax entirely. Risky if donor health uncertain, but maximally tax-efficient if safe.
Belgian expats often retain Belgian property (family home, maison secondaire). Belgian-situated property remains within Belgian inheritance tax net on death regardless of emigration. Regional rates apply based on deceased's last fiscal domicile in Belgium (often a Belgian region where they lived before moving to Spain).
Belgian real property CGT: generally exempt for 5+ year held private residence; otherwise progressive rate. Non-resident owners face Belgian CGT on sale.
On inheritance: heir takes at stepped-up value for Belgian CGT purposes; subsequent heir sale measures from inherited value. For Spanish-resident Belgian heirs inheriting Belgian property, no step-up issue for Belgian tax; Spanish Modelo 720 reporting obligation for the foreign asset.
Belgian tax residence turns on habitual residence, family seat or centre of economic interests. Emigration requires genuine break. Belgium-Spain income tax treaty (1970, updated) allocates primary rights between the two countries. For IHT specifically no treaty — each country applies its own rules, Spanish Article 23 provides partial relief.
The 5-year Belgian inheritance-tax lookback is separate from income-tax residence. A Belgian expat can be Spanish income-tax resident from year 1 but still Belgian-inheritance-tax-regional-resident for years 1–5 post-emigration. Dual-track position matters for planning.
Belgian law recognises three couple statuses: marriage (huwelijk/mariage), statutory cohabitation (wettelijke samenwoning/cohabitation légale), and factual cohabitation (feitelijke samenwoning/cohabitation de fait). Statutory cohabitation gives partial spouse-equivalent succession rights under 2018 reform — limited reserve, specific exemptions. Factual cohabitation gives no automatic succession rights.
For Belgian expats in Spain, statutory cohabitation may be recognised as equivalent to Spanish pareja de hecho in some regions. Practical advice: register Spanish pareja de hecho in your Spanish community for clear local recognition alongside the Belgian statutory cohabitation.
Our architecture: Belgian-form authentic will (testament authentique) at Belgian notary, covering Belgian assets under Belgian law; Spanish-form notarial will at Spanish notary, covering Spanish assets with Brussels IV Belgian-law election. Coordinated so neither revokes the other. Belgian wills can be registered with the Central Register of Wills (CRT). Spanish wills with Registro General de Actos de Última Voluntad.
Spanish-resident Belgian expats must file Modelo 720 annually on Belgian assets over €50k per category. Belgian bank accounts, Belgian securities, Belgian real property — each category separately. Post-2022 ECJ penalty moderation applies. Cross-checked with Spanish wealth tax declarations in non-bonificado regions.
Belgian EU citizens qualifying for Beckham: 6 years of 24%/47% Spanish tax on Spanish source only, non-Spanish assets outside Spanish net including IHT. During Beckham, Belgian assets sheltered from Spanish IHT exposure. Belgian side operates independently — regional regime applies on worldwide if Belgian-resident, on Belgian-situated only if emigrant.
Belgian retirees commonly choose Costa del Sol (Andalusia), Costa Blanca (Valencia), Canary Islands and Mallorca. Post-reform regional Spanish IHT landscape delivers near-zero IHT for Group I/II close family across major expat regions. Wealth tax (Madrid/Andalusia bonificado) and income tax rates drive differentiation.
For Belgian expats still within the 5-year Belgian inheritance tax lookback, Belgian regional regime is the dominant tax — Spanish bonificación reduces Spanish side to minimal. Beyond 5 years, Spanish side is the only non-trivial tax on non-Belgian-situated assets, and regional Spanish optimisation dominates.
Belgium has three regional inheritance regimes and no IHT treaty with Spain. The 5-year lookback rule drives planning. We coordinate droits de succession, Brussels IV election and Spanish regional bonificación.
Request a Belgian Estate ConsultationParents resident in Spain with children in Belgium; non-resident property owners leaving Spanish assets to heirs abroad; surviving spouses, siblings, aunts and uncles, grandparents — every cross-border configuration follows a different rulebook.
Belgian couple from Flanders retired Costa del Sol, year 7 Spanish residence — beyond 5-year Belgian lookback. Husband dies with Antwerp apartment (€400k), Marbella villa (€650k), Belgian pension. Belgian droits: Flemish regional regime on Belgian-situated Antwerp apartment only (spouse family home exemption may not apply if no longer family home). Spanish IHT Andalusia Group II 99% bonificación. Near zero Spanish; modest Belgian on Antwerp.
Belgian IT professional on Beckham Year 3, Barcelona apartment (€450k), Belgian investments and pension retained. Year 3 — still within 5-year Belgian lookback. Dies. Beckham scope: non-Spanish assets outside Spanish base. Belgian regional droits apply on worldwide (within 5 years) — Brussels Region rates (assuming Brussels domicile pre-emigration). Spouse exemption on Belgian part of family home if retained. Net: Belgian tax dominates; Spanish side only Barcelona apartment with Group II regional bonificación.
Belgian-resident couple owns Mallorca villa (€700k). Husband dies in Belgium. Spanish IHT non-resident on villa with 2014 ECJ Balearic election — reformed 2023 Group II bonificación. Belgian droits on worldwide estate (Belgian-resident) including Mallorca villa. Flemish Region 3–27% direct line. Belgian side dominates; Article 23 unilateral credit for Spanish paid IHT (small).
Belgian parent in Flanders gifts €500k to Spanish-resident daughter by Belgian bankgift (informal, unregistered). Zero Belgian gift tax if parent survives 3 years (Flemish lookback). Spanish gift tax Valencia Group II 99% bonificación post-May 2023 — near zero. Extremely efficient. Risk: parent dies within 3 years — gift added back to Flemish droits base.
Belgian-resident owner of Belgian SPRL/BVBA (unrealised gain €3m) relocates to Madrid. Belgium has no formal exit tax on shareholdings at emigration (unlike Norway/Denmark). But 5-year Belgian lookback rule catches worldwide estate if death within 5 years. Beckham Law shelters from Spanish IHT on Belgian assets during regime. Post-5-year mark clean emigration; before, Belgian regional regime applies.
Belgian statutory cohabitants (wettelijke samenwoning) in Canary Islands. One dies with villa (€400k). Belgian position: limited reserve, specific partner rules under 2018 reform. Spanish IHT: if registered as Canarian pareja de hecho, Group II 99.9% bonificación. If not registered, Group IV. Register locally — critical for Canarian access.
Belgian regional regime catches worldwide estate for 5 years post-emigration. Major wealth transfers or death within 5 years fall fully in Belgian net.
Belgium-Spain has no bilateral IHT treaty. Only Spanish Article 23 unilateral credit operates. Plan for dual tax without treaty relief on the Belgian side.
Family home exemption requires retained use as family home by surviving spouse. Letting out or selling on emigration can lose the exemption on first death.
Belgian informal gift (bankgift) is tax-free if donor survives 3 years (Flemish) or 5 years (Walloon/Brussels). Risky if donor health uncertain — registration at low rate often safer.
Belgian-only will forces exequatur at Spanish notary. Dual-will architecture standard for Belgian-Spanish estates.
Without express Belgian-law election, Spanish habitual-residence law may default. Spanish legítima replaces Belgian réserve structure — usufruit and pacte successoral advantages lost.
Largest Belgian expat demographic, particularly from Flanders. Typically Spanish-resident with retained Belgian property.
Beckham-qualifying professionals often applicable; Belgian investments retained. Dual-will file.
Belgian residents with Spanish holiday property. Non-resident Spanish IHT with 2014 ECJ regional election; Belgian regional regime on worldwide estate.
One Belgian, one Spanish national. Brussels IV election in each will — réserve vs legítima outcomes differ.
Bankgift or registered gift strategies. Flemish 3% movables rate combined with Spanish regional bonificación = very efficient.
No Belgian exit tax but 5-year lookback rule. Company holding structures and timing matter.
Brussels IV applied, wills drafted, Belgium and Spanish tax positions coordinated, deadlines tracked.
