For control of a family company, the Dutch STAK and the Belgian certification foundation are the proven tools; Luxembourg achieves the same with share classes and usufruct in a SOPARFI. For portfolios, the Luxembourg SPF is the cheapest. But residence decides: Belgian families do best with the Belgian foundation, Dutch families with the STAK, and Luxembourg families with company-based tools.
Three countries, three answers to the same question
Families who want a foundation in the Benelux meet three different systems. Luxembourg has no private foundation and offers workarounds: the SPF, a SOPARFI with family articles, partnerships, fiducies and life insurance. The Netherlands has the stichting, which may not pay its founders, and the STAK for family companies. Belgium has a genuine private foundation and a certification regime built for family businesses.
Which works best depends far more on where the family lives than on where the vehicle sits, because each country taxes its own residents on foreign foundations and companies.
Workarounds
SPF, SOPARFI, SCSp, fiducie, life insurance; no family foundation since the 2013 bill stalled.
Stichting and STAK
No payments to founders; STAK for control; APV taxes family foundations through founders and heirs.
Private foundation
Real private foundation; certification of shares; annual tax on assets since 2024.
The tools compared
| Luxembourg (SPF / SOPARFI / SCSp) | Netherlands (stichting / STAK) | Belgium (private foundation) | |
|---|---|---|---|
| Legal form | Companies and partnerships | Foundation | Foundation |
| Separate control from value | Share classes, usufruct, general partner | STAK certificates | Certification |
| Payments to the family | As shareholders or partners | No payments to founders or board; relatives only for a social purpose | Within the disinterested purpose |
| Tax on the vehicle | SPF 0.25% subscription tax; SOPARFI corporate tax; SCSp transparent | None unless it runs a business; STAK transparent | Legal entities tax; 0.15–0.45% annual tax on assets above EUR 50,000 |
| Look-through for residents | Resident's own country decides | APV attributes assets to founder and heirs | Cayman tax for foreign constructions, not for Belgian foundations |
| Treaties and directives | SOPARFI yes; SPF no | Not applicable (foundation); holding below may have them | Not applicable; holding below may have them |
| Dissolution | Like any company | Board resolution (STAK) | Court only |
| Legal certainty | High | STAK high; family foundation low | High |
Where the family lives decides
- Belgian families. The Belgian private foundation with certification fits the regional family-company gift regimes; a Dutch STAK risks the look-through tax.
- Dutch families. The STAK with the business succession relief; family foundations are taxed through the founders under APV.
- Luxembourg families. No inheritance tax in direct line on the legal share; a SOPARFI with family articles or an SPF usually suffices.
- Families elsewhere. Their own country's rules on foreign entities, trusts and foundations decide; the Benelux vehicle is chosen for what it holds and who invests.
The foundation is chosen by the family's address, not by the brochure.
