A founder shifting intellectual property from a Dutch BV into a US parent, or a private equity firm routing capital through a Luxembourg holding vehicle, is engaged in international tax structuring whether or not anyone in the room uses the term. The decisions look administrative — which entity signs the licence, where the board meets, which country issues the invoice — but each one fixes how profit is taxed, where it can move, and how much of it survives the journey between jurisdictions. Done carelessly, a structure that looked efficient on a slide collapses the first time a tax authority asks who actually runs the company.
This guide sets out what sound international tax structuring involves for groups operating across the Netherlands, Luxembourg, Switzerland and the United States, and where ambitious plans most often stall.
What international tax structuring actually means
International tax structuring is the deliberate arrangement of legal entities, financing flows and intellectual property across more than one country so that a group’s overall tax position reflects where value is genuinely created. It is not the same as tax avoidance, and the distinction matters more now than it did a decade ago. A defensible structure follows the economics of the business; an aggressive one tries to make the economics follow the tax result.
For a CFO or in-house counsel, the practical question is rarely “what is the lowest possible rate”. It is whether the group can move dividends, interest and royalties between subsidiaries without triggering withholding tax it cannot reclaim, double taxation it cannot relieve, or a reporting obligation it did not see coming. Cross-border tax advisory work begins there — with the flows, not the headline rate.
Substance is the foundation, not an afterthought
The single most common failure in international tax structuring is treating substance as paperwork. Substance requirements — the expectation that an entity has real people, real decision-making and real activity in the country where it is established — now sit at the centre of how authorities test a structure. A holding company with a local address but no directors who meet there, no employees and no genuine function is, in the language of EU law, a shell.
The EU’s anti-tax-avoidance regime made this explicit. The Anti-Tax Avoidance Directive (ATAD) and the proposed Unshell Directive (ATAD 3) set out minimum substance indicators and strip treaty and directive benefits from entities that fail them. An entity that cannot show its own premises, its own bank account under local control, and at least one qualified, resident director is exposed — regardless of how the documents read.
The lesson for anyone building a group is that substance has to be designed in at the start. Retrofitting it after a structure is challenged is expensive, slow, and rarely fully convincing. WVT’s attorneys and tax advisors treat the question “who genuinely runs this entity, and where” as the first design constraint, not the last.
Choosing where the structure lives: the holding jurisdiction
The holding company structure sits at the heart of most international groups, and the choice of jurisdiction for it shapes everything downstream. A good holding location combines a wide treaty network, a participation exemption that frees qualifying dividends and capital gains from tax, political and legal stability, and a tax authority that engages predictably with cross-border arrangements.
The Netherlands earns its place here through an extensive double tax treaty network covering more than 100 countries and a participation exemption that, where conditions are met, exempts dividends and gains from qualifying shareholdings. The Dutch BV remains a workhorse for cross-border holding structures for precisely these reasons. Luxembourg offers a comparable participation exemption alongside a fund and finance ecosystem that suits private equity and family offices in particular; groups building investment vehicles there should read our guide to starting a fund in Luxembourg. Switzerland adds political neutrality and competitive cantonal taxation, though as a non-EU state it cannot rely on EU directives to eliminate withholding tax and depends instead on its bilateral and treaty position.
No jurisdiction is correct in the abstract. The right holding location depends on where the operating companies sit, where the investors are resident, and where the group expects to extract cash — which is why this decision belongs in a structuring conversation, not a brochure.
Treaties, withholding tax and the cost of moving money
A double tax treaty is an agreement between two countries that allocates taxing rights and, in most cases, reduces the withholding tax one country imposes on payments — dividends, interest, royalties — flowing to a resident of the other. Withholding tax is the slice a source country keeps when money leaves it; without treaty relief, a dividend can lose 15% or more before it reaches the parent, and that leakage compounds at every layer of a group.
This is where structure earns its keep. A Dutch or Luxembourg holding company can often receive dividends from an EU subsidiary free of withholding tax under the EU Parent-Subsidiary Directive, and pay them upward under a favourable treaty. Misjudge the chain — insert an entity that fails a treaty’s beneficial ownership test, or one that ATAD 3 would treat as a conduit — and the relief disappears, sometimes retroactively. The beneficial owner, broadly the party with real entitlement to and control over the income rather than a nominee passing it on, must genuinely be the entity claiming the benefit.
Pillar Two and the shrinking value of rate arbitrage
For any group with consolidated revenue above EUR 750 million, the OECD’s Pillar Two global minimum tax has changed the arithmetic of international tax structuring. The rules impose an effective tax rate floor of 15% in every jurisdiction where the group operates, collecting a top-up tax wherever the local rate falls below it. The implication is direct: routing profit through a very low-tax jurisdiction no longer delivers the saving it once did, because the difference is clawed back elsewhere.
What survives Pillar Two is structuring built on genuine substance, treaty efficiency and operational logic rather than rate arbitrage. Groups below the revenue threshold are not directly in scope, but the direction of travel is unmistakable, and a structure designed today should assume the floor will broaden. The OECD’s BEPS framework sets out the current rules and the compliance obligations that accompany them.
Where structures go wrong
Most structuring failures share a small set of causes. The entity has no real substance and cannot survive scrutiny. The financing flows trigger withholding tax nobody modelled. A reporting obligation — DAC6 for certain cross-border arrangements, Pillar Two filings, local beneficial ownership registers — is missed, and a penalty or a challenge follows. Or the structure was built for the business as it was three years ago and never revisited after an acquisition, a new market or a change of investor.
The defence against all four is the same: a structure that maps to the actual business, documented well enough to explain to a tax authority, and reviewed when the business changes. International tax structuring is not a one-time event but a position the group has to be able to defend each year.
The point at which to bring in advisors is before the entities are formed, not after the first audit letter arrives. A group’s international taxation position is far cheaper to design than to repair, and the early decisions — where to hold, how to finance, who sits on which board — are the ones that prove hardest to unwind later. WVT’s corporate tax services team works with founders, CFOs, in-house counsel and investors at that design stage, when the structure is still a choice rather than a constraint.
Frequently asked questions
What is the difference between international tax structuring and tax avoidance?
Sound international tax structuring arranges entities and flows to follow where a business genuinely creates value, using treaties and exemptions as they were intended. Tax avoidance inverts that logic, engineering artificial arrangements whose main purpose is a tax result. The practical test authorities apply is substance: a structure with real people, decisions and activity is defensible, while one that exists only on paper is not.
Which jurisdiction is best for a holding company?
No single jurisdiction is correct for every group. The Netherlands and Luxembourg are frequently chosen for their broad treaty networks and participation exemptions, Switzerland for stability and cantonal rates. The right answer depends on where your operating companies and investors sit and where cash needs to flow, which is why the holding location should be decided alongside the wider structure rather than in isolation.
How do substance requirements affect my structure?
Substance requirements determine whether your entities actually receive the treaty and directive benefits you have planned for. An entity needs genuine local presence — qualified resident directors, its own premises and bank account, and a real function — to withstand scrutiny under ATAD and the proposed Unshell Directive. Without it, withholding tax relief and participation exemptions can be denied, sometimes retroactively, leaving the group worse off than if it had done nothing.
Does Pillar Two make international tax structuring pointless?
Far from pointless, but it changes the objective. Pillar Two’s 15% minimum rate removes the benefit of routing profit through very low-tax jurisdictions for large groups, so structuring built purely on rate arbitrage no longer works. Structuring built on substance, treaty efficiency, holding-regime exemptions and operational logic remains valuable, and for groups near the revenue threshold it is now essential to model the rules before building.
When should we involve tax advisors in a cross-border structure?
Bring advisors in before the entities are formed, while the structure is still a set of choices. The decisions that prove hardest and most expensive to reverse — the holding jurisdiction, the financing flows, board composition and substance — are all made at the outset. Engaging cross-border tax advisory support early is consistently cheaper than repairing a structure after a tax authority has challenged it.
