Dutch and Belgian inheritance tax: the 10-year shadow, erfbelasting, and the Belgium/Netherlands overlap

Dutch nationals in Belgium and France: the 10-year shadow meets two inheritance tax regimes
Dutch nationals who moved to Belgium or France within the past 10 years carry the Dutch erfbelasting shadow simultaneously with the destination country’s own worldwide inheritance tax claim. Two simultaneous worldwide regimes, limited treaty relief, and independent heir-side charges on Dutch-resident heirs of foreign estates.
The Netherlands is a high-emigration country. The Belgian and French borders are the most common intra-EU destinations. Both corridors share a structural feature that makes them particularly severe: the Dutch 10-year shadow overlaps with the destination country’s own worldwide inheritance tax during exactly the same period.
Principle 01 — The Dutch 10-year shadow (Successiewet)
Dutch nationals who emigrate retain Dutch erfbelasting (inheritance tax) exposure on their worldwide estate for 10 years after departure. This applies regardless of where they now live and regardless of any new tax residence they have established. A Dutch national who moved to Brussels in 2019 carries worldwide Dutch erfbelasting exposure until 2029.
Dutch erfbelasting rates:
| Relationship | Rate | Key exemptions |
|---|---|---|
| Spouse/partner | 10–20% | €723,526 exempt (2026) |
| Children | 10–20% | €22,918 per child (2026) |
| Grandchildren | 18–36% | €22,918 |
| Other | 30–40% | €2,658 |
Principle 02 — Netherlands/Belgium: dual worldwide regime overlap
The Netherlands/Belgium DTA on inheritances provides structured relief — domicile tie-break and credits both ways. However, the DTA was drafted before the modern Dutch 10-year shadow provisions and may not fully address the overlap during the shadow period. Dutch-resident heirs independently face Dutch erfbelasting on worldwide assets received — separately from the DTA’s estate-side allocation.
Principle 03 — Netherlands/France: the most severe bilateral overlap
The Dutch/France corridor is one of the most severe within the EU for combined exposure:
- Dutch 10-year shadow: worldwide Dutch erfbelasting during the shadow period on global assets including French assets
- French worldwide succession tax: French fiscal domiciliary faces French succession tax on worldwide estate under art.750 ter §1, including Dutch and global assets
- French heir-side art.750 ter §2: French-resident heirs independently face French succession tax on worldwide assets received — even after the Dutch shadow has expired
- Netherlands/France DTA (1983): provides partial relief — but predates both the modern Dutch shadow provisions and France’s art.750 ter §2 amendment in its current form
Principle 04 — Dutch-resident heirs: the independent heir-side charge
Dutch-resident heirs face Dutch erfbelasting on worldwide assets received, independently of whether the deceased is within their own 10-year shadow. A Dutch-resident child who inherits from a French-domiciled deceased (with no Dutch shadow) independently owes Dutch erfbelasting on their received share of the French estate — including French property — under the Dutch heir-side residence rule.
This mirrors the French art.750 ter §2 mechanism. It is entirely separate from the estate-side DTA allocation. Both the Dutch heir-side charge and the French art.750 ter §2 charge can operate on the same assets through independent mechanisms.
Principle 05 — Belgian inheritance tax: the three regional systems
Belgian inheritance tax is administered regionally. The applicable system depends on where the deceased was domiciled at death:
- Flanders (Flemish Region): Erfbelasting. Direct family (spouse/children): 3–27%. Siblings: 25–55%. Others: 25–65%.
- Brussels Capital Region: Droits de succession. Direct family: 3–30%. Siblings: 20–65%. Others: 40–80%.
- Wallonia: Droits de succession. Direct family: 3–30%. Siblings: 20–65%. Others: 30–80%.
Belgian inheritance tax applies to worldwide assets of Belgian-resident deceased and to Belgian-situs assets of non-resident deceased. A Dutch national domiciled in Antwerp (Flanders) faces Flemish erfbelasting on their worldwide estate.
The key planning action for Dutch nationals moving to Belgium or France: calculate the Dutch shadow expiry date on departure. During the shadow period, obtain coordinated advice from Dutch and Belgian/French specialists simultaneously — not sequentially. The DTA in each corridor reduces but does not eliminate dual worldwide scope. Dutch-resident heirs add an independent layer that the DTA does not fully address.
Planning triggers — you should be reviewing this if…
- You are a Dutch national who moved to Belgium or France within the past 10 years
- You have Dutch-resident heirs (parents, siblings, adult children still in the Netherlands) who independently face Dutch erfbelasting on worldwide assets they inherit
- You are in Belgium and have not assessed which regional system (Flanders, Brussels, Wallonia) applies to your estate
- Your estate plan was drafted in only one country without assessing the other
- You have French-resident heirs — art.750 ter §2 may apply independently of your Dutch/Belgian position

- Which Belgian regional system applies to your estate — depends on your specific Belgian domicile
- How the Dutch shadow interacts with the DTA in your specific overlap window
- Whether Dutch-resident heirs face erfbelasting on worldwide assets received — depends on their residence history
Frequently Asked Questions
Is there inheritance tax in the Netherlands?
Yes — Dutch erfbelasting (inheritance tax) applies to the worldwide estate of Dutch-resident deceased and to Dutch-situs assets of non-resident deceased. Rates: 10–20% for spouses/partners and children; 18–36% for grandchildren; 30–40% for others. Dutch nationals who emigrate retain worldwide Dutch erfbelasting exposure on their estate for 10 years after departure. Dutch-resident heirs additionally face erfbelasting on worldwide assets received, regardless of where the deceased was domiciled.
Is there inheritance tax in Belgium?
Yes — Belgium has regional inheritance tax administered by three regional systems depending on where the deceased was domiciled at death: Flemish erfbelasting (Flanders), and droits de succession (Brussels Capital Region and Wallonia). Rates vary significantly: direct family (spouse/children) from 3% to 27–30% depending on region and estate size; siblings from 20–25% to 55–65%; others from 25–40% to 65–80%. Belgian inheritance tax applies to the worldwide estate of Belgian-resident deceased.
Do Dutch nationals in Belgium still owe Dutch inheritance tax?
Yes — for up to 10 years after leaving the Netherlands. Dutch nationals who emigrate retain worldwide Dutch erfbelasting exposure for 10 years under the Dutch Successiewet. A Dutch national who moved to Belgium in 2020 carries worldwide Dutch erfbelasting exposure until 2030, simultaneously with Belgian inheritance tax applying to their worldwide estate as a Belgian-resident deceased. The Netherlands/Belgium DTA on inheritances provides structured relief but may not fully eliminate the dual worldwide scope during the overlap period.
Can both Dutch and French inheritance tax apply to the same estate?
Yes — during the Dutch 10-year shadow period. A Dutch national in France within 10 years of emigrating faces: (1) worldwide Dutch erfbelasting during the shadow period; (2) worldwide French succession tax as a French fiscal domiciliary. Both claim the entire worldwide estate. The Netherlands/France DTA (1983) provides partial relief with credits and domicile tie-break, but the DTA predates the modern Dutch shadow provisions and may not address the overlap comprehensively. French-resident heirs additionally face art.750 ter §2 independently.
Does Belgium have a bilateral inheritance tax treaty with the Netherlands?
Yes — the Netherlands and Belgium have a bilateral inheritance and estate tax convention that provides a domicile tie-break, situs allocation for real property, and credit mechanisms. This reduces double taxation for most estates. However, the DTA does not fully address: (1) the Dutch 10-year shadow during the overlap period when the deceased is simultaneously Dutch-shadow-exposed and Belgian-resident; (2) heir-side Dutch erfbelasting on Dutch-resident heirs receiving assets from Belgian estates.
What is the inheritance tax rate in Flanders (Belgium)?
Flemish erfbelasting rates for direct family (spouse, children, grandchildren, parents): 3% on first €50,000; 9% up to €250,000; 27% above €250,000. For siblings and others: rates rise significantly, reaching 55–65% for non-relatives. Flemish erfbelasting applies to the worldwide estate of deceased domiciled in the Flemish Region at death, and to Flemish-situs assets of non-resident deceased. Brussels and Wallonia have separate rate schedules under their own droits de succession systems.
