Is using a STAK or foreign holding legal?

Yes, these are legal structures. They rely on genuine features of Dutch and EU law, such as a foundation having no owners and participation exemptions between companies. What makes them legal is proper setup, professional execution and ongoing compliance — and above all real economic substance. Without substance, tax authorities can disregard the structure entirely.

What are CFC rules and why do they matter here?

CFC (controlled foreign corporation) rules let high-tax countries tax the profits of a foreign company directly on your personal return if you personally own it, even if you never bring the money home. They exist to stop people parking profits offshore tax-free. A STAK owning the foreign shares instead of you personally is what prevents these rules from applying directly.

How do you access money that's accumulating inside an offshore company?

Rather than paying yourself a heavily taxed dividend, the foreign company can lend the money to you privately. Receiving a loan is generally not a taxable event. Alternatively, the foreign holding can invest its cash into international tax-exempt real estate.

What is 'fraus legis' and how can it break the structure?

Fraus legis is a principle Western tax authorities use to disregard a structure whose only purpose is avoiding tax with no real economic substance. They ask where the company is actually managed from. If you run everything yourself from home while foreign directors do nothing, they can rule the real management sits in your home country and tax it accordingly.

Do these structures only exist in the Netherlands?

No. The STAK is the Dutch version of a broader concept. Germany has the Familienstiftung, Belgium has the private stichting, and the UK and other common-law jurisdictions use trusts. In every case the underlying principle is the same: separating the person who benefits from the wealth from the person who formally owns it.

How the Wealthy Cut Their Taxes Without Leaving High-Tax Countries

If you want to pay lower taxes, the advice is always the same. Pack your bags and move to Dubai, move to Monaco, or move to some island in the Caribbean. But what if you want to keep living in your current country? The standard answer is that there's nothing you can do.

That answer is wrong. The people at the very top aren't paying anywhere near the taxes you're paying. Not because they break laws, and not because they have a secret offshore account in the Cayman Islands, but because they structure their income differently. They treat the tax system like software, and like any software, it has bugs and glitches.

What follows is how international tax law is actually implemented, and how wealthy people use legal structures, structural loopholes, and the interaction between different tax systems to lower their effective rate while still living in some of the highest-tax countries in the world. These are legal structures, but they require proper setup, professional execution, and ongoing compliance. Done wrong, they attract scrutiny — and that matters more than any of the mechanics.

Why high-tax countries can follow your money anywhere

Most people operate entirely within the default tax structure: employees, traditional business owners, people who hold assets in their own name. They pay full rate every single time. To understand why the loopholes exist, you first need to understand how high-tax countries actually tax people.

Countries like the Netherlands, Germany and Finland operate on a worldwide taxation model. As a tax resident, you're required to declare and pay tax on everything you own and earn globally. In the Netherlands the system is split into boxes:

Box 1 — employment and active income, personal income tax up to 49.5%.
Box 2 — dividends and withholding tax, between 24.5% and 31%.
Box 3 — assets such as savings and investments, taxed at 36%.

The entire system is designed around one idea: following your money wherever it goes. It doesn't matter if you set up an offshore company in the Virgin Islands or hold a bank account in Hong Kong — it's all taxable. With global reporting standards tightening and cooperation between countries getting more advanced, it's practically impossible to truly hide anything. Anti-money-laundering rules, reporting requirements and ultimate beneficial ownership (UBO) rules all exist to connect every structure, every bank account and every asset back to a real individual.

So here's the first question that opens everything up: what happens when a structure technically doesn't have an owner at all?

The ownerless entity: separating legal and economic ownership

The foundation of this mechanism is the separation of legal and economic ownership. Normally, when you own a company you own it completely — the control, the voting rights and the financial benefits all sit with you. Certain legal structures make it possible to split those apart.

In the Netherlands this is done with a STAK, which stands for stichting administratiekantoor — a foundation administration office designed to hold and administer assets. The key feature under Dutch law is that a foundation has no shareholders, no members and no owners. It legally belongs to itself. You can compare it to a trust.

Setting one up follows a clear sequence:

The STAK is incorporated through a notarial deed, the formal legal document that establishes the foundation and its purpose.
A private document called the administration conditions is drafted, defining exactly how the structure operates and under what conditions economic benefits can flow from the foundation to you.
You transfer your company shares into the STAK. In return, the STAK issues you certificates representing the economic interest of those shares.
You or a trusted representative takes a seat on the board of the STAK. This lets you retain 100% control over the underlying company without owning the shares privately.

Why this changes the tax picture

When you personally own shares, the government can directly connect the company, the dividends, the appreciating value and the underlying assets back to you and tax everything accordingly. But a foundation has no owners and no share capital. Legally, the assets held inside the foundation float in an entity without an owner.

Because the STAK has no shareholders, there's no direct private owner to list in the UBO register. What typically appears instead are the board members — which can be a trusted representative or even foreign directors, giving you an extra layer of privacy.

If the certificates issued to you personally are valued using more tax-efficient methods — for example based on the lower non-tradable value, or placed into a structure where the assets are categorized as separate private assets held abroad — the local tax authorities lose their direct grip on the progressive capital wealth tax in box 3. The individual no longer owns the shares.

This does not magically make taxes disappear. It needs proper planning, which is why it's often combined with a foreign structure.

Combining a STAK with a foreign holding

In a normal Dutch situation the same stream of money is taxed multiple times. First at company level through corporate income tax, currently between 19% and 25.8%. Then, when the remaining profits are distributed to the owner personally, dividend tax applies — currently between 24.5% and 31% (box 2).

What wealthy entrepreneurs and high-net-worth individuals often do is place a STAK above an international structure in a more tax-efficient jurisdiction, frequently elsewhere in Europe — a holding or operating company in places like Cyprus, Malta or Bulgaria — using EU participation exemption systems and the EU Parent-Subsidiary Directive.

Take Cyprus as an example. Because of these tax treaty systems, profits can flow between a Dutch company and a Cyprus company without withholding tax. Instead of the profits flowing directly to you personally, the operating profits flow into the Cyprus holding company. The Cyprus holding simply does not distribute the dividends — the money stays in the company.

Why the STAK is what makes this survive CFC rules

Here the STAK becomes essential. You do not personally own the shares of that Cyprus holding in your own name — the STAK does. If you, as a Dutch resident, personally owned 100% of a foreign company, high-tax countries enforce CFC rules (controlled foreign corporation rules).

Those rules say that if you live in the Netherlands, Germany or Finland and personally own a passive holding company in, say, Cyprus, they don't care whether you bring the money home. They tax the foreign company's profits directly on your personal tax return. CFC rules exist specifically to stop people from opening a company offshore and parking their profits there tax-free forever.

But because the STAK is the legal owner of the foreign shares, and the foundation has no owner according to the law, there is on paper no direct control over the foreign company. The money never enters your home country's banking system, and you don't legally own the offshore shares. The profits are legally and indefinitely accumulated and compounded inside the foreign holding at low corporate tax rates. In the Cyprus case that's 15% corporate tax, though this can also be structured in other jurisdictions. It is very case by case and depends on the individual's specific situation.

How you actually use money that's stuck offshore

An obvious problem: if the money sits inside an offshore company, how do you use it for day-to-day life?

Instead of distributing profits as a heavily taxed dividend to your personal account, the foreign company can lend the money to you privately. By law, receiving a loan is mostly not a taxable event. This lets you fund your lifestyle with liquidity borrowed from your structures. Alternatively, the foreign holding can use its cash to invest into international tax-exempt real estate.

Substance is what makes it defensible — or not

This is where a lot of people get it wrong. None of this works if it's just a paper shell. Western tax authorities use the principle of fraus legis: if the only purpose of a structure is to avoid tax with no real economic substance behind it, they can ignore the structure and tax you anyway.

The key question they ask is: where is the company actually being managed from? If you're sitting on your couch in Amsterdam managing a Cyprus holding and a STAK with foreign directors who do absolutely nothing, the Dutch tax authorities can argue the real management is still in the Netherlands and tax it accordingly.

Real substance means:

Foreign directors who actually make decisions.
A real office or registered presence abroad.
Genuine operational activity outside your home country.

Bottom line: the structure only holds up if the substance is real, which is exactly why professional execution matters more than the paperwork.

The same idea exists across Europe

The STAK is simply the Dutch version of a much broader concept found across the continent:

Country	Structure	Notes
Netherlands	STAK (stichting administratiekantoor)	Foundation holding and administering assets
Germany	Familienstiftung	Family foundation, popular among wealthy German families
Belgium	Private stichting	Operates under many of the same principles
UK / common-law jurisdictions	Trust	Same underlying principle

The underlying principle is always the same: the person benefiting from the wealth is legally separated from the person who formally owns it.

What to do with this

None of the above is professional tax advice. These structures are highly complex and extremely case by case. They need to be implemented correctly based on your residency, your citizenship, your business activities and your overall situation. There's no universal best strategy that works for everyone, and modern tax authorities look aggressively at international structures that exist purely on paper without real economic substance.

If you're paying full rate on everything, the first step isn't to copy a structure — it's to establish whether corporate restructuring, a foreign holding or a second residency actually fits your specific residency, citizenship and activities. That answer is individual, and getting it wrong is more expensive than doing nothing.
