For families with assets across multiple jurisdictions, the holding structure is the long-term architecture on which everything else sits. The right structure produces tax efficiency, governance clarity, succession capability, and the operational flexibility to respond to changes in family circumstances and in the jurisdictions involved. The wrong structure produces ongoing friction, periodic restructuring costs, and (occasionally) tax outcomes that nobody intended. The difference between the two is usually decided at the design stage.
What a holding structure does
At its core, a family holding structure does three things. It holds the family's assets — operating businesses, real estate, investment portfolios, intellectual property, and other valuable interests — in vehicles that are owned (directly or indirectly) by the family. It governs the relationship between the family members who participate, defining who decides what, who receives what, and how the arrangement changes over time. And it provides a framework within which assets move, generations transition, and the family's relationship with the legal and tax systems of relevant jurisdictions is managed.
The specific architecture varies enormously. Some families use a single holding entity in a chosen jurisdiction. Others use multi-layer structures with operating companies, holding companies, intermediate vehicles, and (sometimes) trust or foundation structures. Some are designed around concentrated control by a single family principal; others around distributed governance among multiple family members. There is no universal right answer — there is the right answer for a given family.
Jurisdictional selection
The choice of jurisdictions in which the structure sits is the foundational decision. The relevant factors include: the location of the underlying assets and operations; the tax-residency positions of the principal family members; the requirements of banks, regulators, and counterparties with whom the family does business; the political and regulatory durability of the candidate jurisdictions; and the family's long-term plans for where members will live and how succession will operate.
For families with operations and members in Europe and the Gulf, common patterns include European holding jurisdictions (the Netherlands, Luxembourg, Switzerland, and others) combined with UAE entities for Gulf-side operations and holding functions. The UAE has become a more credible holding jurisdiction following the maturation of its corporate-tax regime, the development of DIFC and ADGM as financial centres, and the country's growing treaty network. Where Danish family members are involved, the Danish-side tax-residency and exit-tax considerations need to be integrated from the outset.
The substance requirement
Every layer in a modern cross-border structure now requires defensible substance. Empty holding companies that exist on paper but do not function are no longer reliable. Every entity needs operational reality — decision-making activity, qualified personnel, physical presence, and documented governance — proportionate to its role in the structure.
Building this substance is the long-term work of operating a cross-border structure. It involves real costs (office space, qualified directors, board meetings, formal decision-making procedures) and real time. Families that approach the structure as a one-time setup followed by passive operation tend to encounter problems. Families that approach it as ongoing operational architecture tend to do well.
Generational planning
A family holding structure that does not address generational transition is not a complete structure. The arrangements need to anticipate the eventual handover from current principals to next-generation family members — including the legal mechanisms (share transfers, trust distributions, beneficiary designations), the tax consequences (succession taxes where applicable, exit-tax-type events on cross-border transfers), and the governance implications (who decides what, after the current principals are no longer the decision-makers).
Where succession is contemplated to multiple family members, the structure also needs to provide for the long-term relationship between branches of the family. This is the area where family disputes typically emerge — and where careful initial design saves significant later cost. Governance provisions, dispute-resolution mechanisms, exit rights for individual family members, and the framework for family decision-making over time are part of the design work.
Treaty and reporting framework
Where the structure relies on treaty benefits for withholding-tax reduction or double-taxation relief, treaty eligibility — including beneficial-ownership requirements and principal-purpose tests — needs to be analysed at the design stage and maintained throughout operation. The reporting frameworks under various international transparency initiatives (CRS, FATCA, ultimate-beneficial-owner registers) need to be understood and complied with across all relevant jurisdictions.
These are not optional. Families operating cross-border structures need to be reporting in all the jurisdictions where reporting is required, and the structure needs to be designed so that those obligations are met without practical difficulty.
The ongoing work
A family holding structure is operated, not just set up. The ongoing work includes annual filings in each relevant jurisdiction, periodic governance activity (board meetings, family-council meetings, annual reviews), tax filings and treaty positioning, response to changes in the family's circumstances, and (importantly) periodic reviews of the structure itself to ensure it continues to fit the family's evolving position.
For most families, the right model is to engage external counsel on a retainer basis to provide this continuing support. The cost of professional ongoing support is significantly lower than the cost of running into problems because the structure has been left to operate without attention.
Closing observation
For families with cross-border assets and members, the holding structure is among the most consequential set of decisions the family makes. The structures that work well are the ones designed with care from the outset, operated with discipline over time, and reviewed periodically as the family and the jurisdictions evolve. The structures that produce problems are the ones assembled quickly, operated passively, and reviewed only when something goes wrong. The difference is principally a matter of intention.
