Swiss Foundation vs a Private Company for Holding Family Assets
By Hansruedi Mueller, Swiss foundation lawyer · Published 21 July 2026 · Last updated 21 July 2026
Families with a home, a portfolio and perhaps a holiday property often ask whether to park those assets in a Swiss foundation or in a private company (a GmbH or an AG) they own themselves. The two answer very different questions. A foundation, under the Swiss Civil Code Article 80, is an ownerless entity that holds assets for a fixed purpose; once you endow it, the wealth is no longer yours. A private company keeps the assets firmly in your hands: you hold the shares, and the shares stay in your estate.
This page is about passive family wealth, a residence, securities, maybe a second property, not about owning an operating business. For the business-holding case, with participations, dividends and the participation deduction, see our separate guide on the foundation versus a holding company. Here the practical questions are narrower and more personal: what does each structure cost in tax, who really controls the assets, what happens on death, and how well are the assets protected.
The short version is that neither is a tidy “wrapper” for a family’s private wealth. A company adds a layer of corporate tax and some awkward rules when the family actually uses the assets. A foundation removes the assets from your control for good and, if it is a family foundation, is boxed in by law. Often the right answer is direct ownership, or a foundation used deliberately for the part of the wealth you genuinely want to give away.
Key takeaways
- A foundation owns its assets outright; a company’s shares stay in your estate and are exposed to your personal creditors and to forced heirship.
- A private company adds a second tax layer: it pays corporate tax on income, and you are taxed again when profits are distributed.
- Putting a family home into a company creates a taxable benefit when you live in it, a common and expensive trap.
- Moving property into either structure can trigger property gains tax and transfer tax in most cantons.
- A family foundation cannot be a general wealth-holding vehicle: Article 335 limits it to education, upbringing and support.
Foundation or company: what actually differs
The table sets out the practical differences for a family holding passive assets. Read the sections below before drawing a conclusion, because the “best” choice depends on whether you want to keep the assets or give them away.
| Question | Swiss foundation | Private company (GmbH/AG) |
|---|---|---|
| Who owns the assets | The foundation itself; no owner | You, through your shares |
| Are the assets in your estate | No, they leave your estate | Yes, the shares are in your estate |
| Forced heirship | Assets fall outside it once endowed | Shares are subject to it |
| Income tax on returns | Foundation taxed as an entity (unless charitable) | Company taxed, then you are taxed on distributions |
| Wealth tax | On the foundation’s capital (entity level) | On the value of your shares (personal level) |
| Using the assets yourself | Only as a defined beneficiary within the purpose | Private use of company assets is a taxable benefit |
| Asset protection | Strong once irrevocably endowed | Weak: shares are reachable by your creditors |
| Reversibility | Irrevocable | Fully reversible: sell, liquidate, restructure |
A company keeps ownership; a foundation gives it away
A private company keeps you in control. You own the shares of the GmbH or AG, you appoint yourself director, and you decide what the company buys, holds or sells. Nothing about the wealth leaves your hands; you have simply placed it inside a corporate shell. That is the appeal for families who want a tidy holding structure without surrendering ownership.
A foundation does the opposite: it takes the assets out of your ownership altogether. After the endowment, the wealth belongs to the foundation and serves the purpose in its deed, administered by a board. You can be a beneficiary, but you are no longer the owner, and you cannot simply take the assets back. If keeping control is your goal, that alone often settles the question in favour of direct ownership or a company.
The tax layer a company adds
A private company is taxed on its income before you see a franc of it. Rental income, interest and dividends earned by the company are subject to corporate income tax; when the company then pays that money out to you, you pay income tax on the distribution. This is the classic economic double burden. Switzerland softens it with partial relief on qualifying dividends from participations of at least 10 per cent, but that relief is designed for business holdings, not for a family that simply wants to hold its own securities and property.
Holding assets directly, by contrast, is taxed once: you declare the income on your personal return and pay wealth tax on the assets. For a family whose aim is to hold passive investments, interposing a company frequently adds cost and administration without a matching benefit. A company earns its keep when there is an active business, reinvestment at the corporate level, or genuine liability separation, not merely as a box around a portfolio.
The family-home trap
Putting the family home into a company is one of the most expensive mistakes in private structuring. When you live in a property your own company owns, the tax authorities treat the below-market or rent-free use as a benefit flowing from the company to you, a hidden profit distribution (verdeckte Gewinnausschüttung). The company is assessed as if it had received a market rent, and you are taxed on the benefit you received. The result can be worse than owning the home in your own name.
Transferring the property into the company is costly in its own right. In most cantons the transfer triggers property gains tax (Grundstückgewinnsteuer) on any increase in value and a real-estate transfer tax (Handänderungssteuer), and the same applies when moving a property into a foundation. Before any property changes hands into either structure, model these cantonal taxes first, because they often outweigh the structuring benefit entirely.
What each does on death
A company keeps your wealth inside your estate. The shares pass under Swiss succession law, which means they are subject to forced heirship: certain heirs have a protected share you cannot freely override. If continuity and keeping the assets undivided matter, shares can still be split among heirs, and a shareholders’ agreement only goes so far.
A foundation takes the assets out of the estate entirely. Once endowed, the assets belong to the foundation, not to you, so they do not pass to heirs and are not fragmented by a succession. This is the foundation’s real strength for a family: it locks chosen assets to a purpose across generations. The trade-off is bluntly stated, you have given the assets away, and cannot change your mind.
Asset protection: shares are reachable, endowed assets are not
Company shares do not protect the underlying wealth from your own creditors. The company may shield you from the liabilities of a business it runs, but the shares themselves are part of your personal assets and can be seized to satisfy your personal debts. A family that puts its portfolio in a wholly owned company has not protected that portfolio from its own creditors at all.
An irrevocably endowed foundation does protect the assets, because they are no longer yours. Subject to the rules that let creditors claw back transfers made to defeat them, and to forced-heirship protections, assets given to a foundation are beyond the reach of the founder’s later creditors. This is why asset protection is a genuine reason to use a foundation, and a poor reason to use a private holding company. Our guide to family foundation asset protection covers this in depth.
The Article 335 limit on family foundations
A Swiss family foundation cannot be used as a general wealth box. Under Article 335 of the Civil Code, a family foundation may serve only defined family purposes, the upbringing, education, endowment or support of family members. A foundation set up simply to hold and grow a family’s wealth, or to fund a comfortable lifestyle, is a prohibited “maintenance” foundation and will not stand. This is the single biggest misunderstanding families bring to the foundation idea. Our explainer on Article 335 and family foundation rules sets out exactly what is and is not allowed.
Where a broader wealth-holding purpose is genuinely wanted, the vehicle is usually a charitable or mixed foundation, not a pure family foundation, and the charitable element must be real to earn the associated tax treatment. That is a different structure with different obligations, and it is not a workaround for keeping wealth under private family control.
So which should a family use?
For passive private wealth you want to keep and use, direct ownership is usually simplest and cheapest, and a private company rarely pays for itself unless there is an active business or a real liability concern. For the part of your wealth you genuinely want to place beyond your estate and dedicate to family provision or a cause, a foundation is the right tool, within the limits of Article 335 for family purposes. The honest planning question is not “company or foundation” but “which assets do I want to keep, and which do I want to give away”. Once that is clear, the structure follows.

Frequently asked questions
Should I hold my family’s investments in a company or a foundation? For passive investments you want to keep and control, a private company usually adds a layer of corporate tax and administration without a clear benefit, and direct ownership is often better. A foundation suits the part of your wealth you want to place permanently outside your estate for family provision or a cause, within the limits the law sets for family foundations.
Is it tax-efficient to hold a portfolio in a Swiss company? Generally no, for a purely passive family portfolio. The company pays corporate tax on income, and you are taxed again when it distributes profits. The partial relief on qualifying dividends is aimed at business participations, not at a family holding its own securities, so the structure often costs more than owning the assets directly.
What happens if I put my home into my own company and live in it? The tax authorities treat living in a company-owned home rent-free or below market as a benefit from the company to you, a hidden profit distribution. The company is taxed as if it had earned a market rent and you are taxed on the benefit. This commonly makes company ownership of a family home more expensive than personal ownership.
Does moving property into a foundation or company trigger tax? In most cantons, yes. Transferring real estate typically triggers property gains tax on any increase in value and a real-estate transfer tax, whether the recipient is a company or a foundation. These cantonal taxes should be modelled before any transfer, because they frequently outweigh the intended structuring benefit.
Are company shares protected from my personal creditors? No. The shares of a company you own are part of your personal assets and can be reached by your personal creditors. A company can separate you from the liabilities of a business it operates, but it does not protect the wealth held inside it from claims against you personally.
Does a foundation protect assets better than a company? Yes, when the foundation is irrevocably endowed, because the assets are no longer yours. Subject to rules that allow creditors to reverse transfers made to defeat them and to forced-heirship protections, endowed assets are beyond the founder’s later creditors. Company shares offer no such protection because they remain your property.
Can a family foundation simply hold and grow our wealth? No. Under Article 335 of the Civil Code, a family foundation may only serve upbringing, education, endowment or support of family members. A foundation set up to accumulate wealth or fund a general lifestyle is a prohibited maintenance foundation and will not be accepted.
How are the assets treated on death in each structure? Company shares stay in your estate and pass under Swiss succession law, including forced heirship, so they can be split among heirs. Assets endowed to a foundation leave your estate entirely, do not pass to heirs and are not fragmented by a succession, which is the foundation’s main advantage for keeping wealth intact across generations.
Is a private company ever the right choice for family assets? Yes, when there is an active business, meaningful reinvestment at the corporate level, or a genuine need to separate liability. As a shell around a passive portfolio or a family home, it usually adds tax and administration without a matching benefit.
Can I combine direct ownership, a company and a foundation? Often that is the sensible answer: keep liquid assets and the home in personal ownership, use a company only where there is a real business, and use a foundation for the portion you want to dedicate permanently to family provision or philanthropy. The right mix depends on your assets and goals, which is worth mapping with an adviser.
