The OpCo-PropCo Model: How Swiss Business Owners Protect Real Assets, Optimise Taxes and Plan Succession

6 November 2026 · by FiPAX

You have spent decades building your company. The workshop, the office building, the plot on the edge of town – much of it financed and paid off through your own effort. And yet that hard-earned value now hangs by the same thread as your day-to-day business: a single key customer, a product defect, a lost lawsuit.

In many Swiss family-owned and traditional businesses, this is the norm. Operations, staff and property sit on the same balance sheet – the so-called single entity. It grew that way over the years, it looks simple, and it worked for a long time. Look closer, though, and it is a concentration risk: everything you own is liable for everything that can go wrong in the business.

The solution institutional investors have used for years is the OpCo-PropCo model: the Operating Company (OpCo) runs the business, the Property Company (PropCo) owns the real estate and leases it to the business. It sounds technical – but at its core it is a deeply entrepreneurial decision. It is about structuring your life’s work so that a setback in the business does not drag everything down with it, so that your children can inherit fairly, and so that you have more options if you ever sell.

In this article we explain how the model works, where it creates real value – and where we honestly advise business owners against it.

1. The Principle: Two Companies, Two Jobs

The idea is simple. Instead of one company doing everything, there are two:

• The OpCo is your actual business. It produces, sells, employs your staff, signs contracts – and rents the premises it works in.
• The PropCo owns the property. It has no production staff and no customers. Its business is calm: it leases its building to the OpCo and receives a market rent in return.

The effect: operating risks stay where they arise – in the OpCo. The property, often the family’s largest and most stable asset, sits alongside it and is legally separate.

Sister Company or Holding?

In practice there are two variants. In the sister company model, you hold the shares of both companies directly as private assets. The two companies sit side by side legally, without a group connection – this offers the strongest separation of liability.

In the holding model, OpCo and PropCo belong to a common holding company. This simplifies liquidity management, because dividends reach the holding level on a tax-privileged basis thanks to the participation deduction (Art. 69/70 DBG) and can be reinvested there. Which variant fits depends on whether protection or flexibility matters more to you.

The Separation Has to Be Lived

An important point many underestimate: two companies on paper are not enough. Courts examine whether the separation is actually observed in practice (separation principle, Art. 52 ZGB). If you sit on both boards, you must safeguard the interests of each company individually (Art. 717 OR).

If money is moved back and forth without agreements, current accounts are offset at will, or rent is sometimes paid and sometimes not, a court may treat the separation as an abuse of rights (Art. 2 para. 2 ZGB) and reach through to the property after all. The protection is only as good as the discipline in everyday business.

Two companies on paper protect nothing. Only a separation that is actually lived makes the property truly safe.

2. Tax: Where the Model Creates Opportunities – and Where the Traps Are

From a tax perspective, the OpCo-PropCo model does not run itself. Set up well, it opens up room for manoeuvre; set up badly, it becomes expensive. The key lever is the rent.

The Rent Must Pass an Arm’s-Length Test

Because you sit on both sides of the lease, the tax authorities look closely. The rent must be what an independent third party would pay – no more, no less.

• If the rent is too high, the OpCo shifts profit to the PropCo. The tax authority adds the difference back to the OpCo’s profit as a hidden profit distribution (Art. 58 para. 1 lit. b DBG).
• If the rent is too low, the PropCo subsidises the business. In that case, income is added back at the PropCo.

In the sister company model, the so-called triangle theory also applies: the tax authority treats the overpayment as if it had first been paid to you as a dividend and then contributed by you to the PropCo. This triggers income tax for you (Art. 20 para. 1 lit. c DBG) – and 35% withholding tax at the OpCo (Art. 4 para. 1 lit. b VStG).

How to Set the Right Rent

To avoid getting there, the rent should be derived methodically and documented. Two approaches are common:

1. Comparable market rent: based on rents actually paid for comparable commercial space in the region (Art. 269a lit. a OR, Art. 11 VMWG). This works well for offices and standard halls – for special-purpose buildings, comparables are often missing.
2. Cost-based rent: calculated from the costs: investment costs, interest, amortisation, maintenance and an appropriate return on the equity invested. The Federal Supreme Court allows a net return of up to two percentage points above the reference interest rate (BGE 147 III 14).

Our practical advice: have the rent confirmed by a tax ruling from the cantonal tax authority before implementation. It takes little time and gives you certainty for years to come.

Triple-Net: Who Pays for the Roof and Façade?

Many PropCo structures use triple-net leases: in addition to rent, the OpCo bears operating costs, insurance, maintenance and repairs. Under Swiss tenancy law this is not straightforward, because the landlord is generally responsible for maintenance (Art. 256 para. 1 OR). Such a transfer only holds if the OpCo is economically compensated – for example through a lower base rent and a long lease term of 10 to 15 years.

Getting Into the Structure: Hive-Down Rather Than Demerger

Most business owners do not start from scratch but with an existing company that already holds the property. So the question is: how do you get it out tax-neutrally?

The obvious route, a demerger (Art. 61 para. 1 lit. b DBG), usually fails for SMEs because of the dual business requirement. Under ESTV Circular No. 5a, a property company only qualifies as a business if it has at least one full-time position for management and rental income of at least 20 times the personnel expense – in practice, around CHF 2 million in rental income per year.

The workable route is usually a hive-down to a subsidiary (Art. 61 para. 1 lit. d DBG in conjunction with Art. 69 ff. FusG): the property is transferred at book value to a new subsidiary without hidden reserves being taxed. The catch: for five years, neither the property nor the shareholding may be sold (Art. 61 para. 2 DBG). Breaching this blocking period triggers the tax retroactively.

Watch Out When Selling the PropCo Later

Selling the PropCo shares rather than the property itself does not automatically avoid real estate capital gains tax. In cantons such as Zurich, Bern or Basel-Stadt, the sale of a property company counts as an economic transfer of ownership and is taxed like a direct property sale.

3. Succession: When Not All Children Want to Run the Business

This is often where the model delivers its greatest human value. In many families the situation is the same: one child wants to take over the business, the others have chosen their own paths. Everyone should be treated fairly – but the company must not break apart in the process.

The New Inheritance Law Creates Additional Room

Since 1 January 2023, the compulsory share of descendants is only half instead of three quarters of their statutory entitlement, and the parents’ compulsory share has been abolished entirely (Art. 471 ZGB). This allows you to allocate OpCo and PropCo shares far more precisely through an inheritance contract or will, without infringing compulsory shares.

4. Financing: Two Borrowers Instead of One

After the separation, your company looks different to the bank – and that is usually an advantage. Instead of one mixed borrower, there are two clearly distinct profiles, each with its own logic:

The Ratios Banks Look At

For the PropCo, two figures matter most. The loan-to-value (LTV) for operating properties is usually capped at 50 to 65% of market value – considerably more conservative than for residential properties. And the debt service coverage ratio (DSCR) shows whether rental income can cover interest and amortisation even under stress:

Banks calculate with an imputed interest rate of 4.5 to 5% plus 1% amortisation. A simplified example: a PropCo with CHF 330,000 net rental income and a mortgage of CHF 3.6 million has a stressed debt service of around CHF 216,000. The DSCR is therefore around 1.5 – comfortably above the usual minimum of 1.20 to 1.35.

The Bank Trap: Cross-Collateralisation

This is where the most common mistake happens in practice. In credit negotiations, the bank asks for the PropCo’s mortgage notes to also secure the OpCo’s operating loans – or for a default by one company to automatically trigger the loans of the other (cross-default).

Signing that undoes the entire protection with a single signature. If the OpCo runs into trouble, the bank goes straight to the property. As part of our debt advisory, we therefore make sure that each company’s loans and collateral stay strictly separate.

A single cross-collateral clause can undo the entire protection of the structure. That is why we always negotiate credit agreements with both companies in mind.

More Options When Selling

The separation opens two interesting doors. In a sale-and-leaseback, the PropCo sells the property to an institutional investor such as a pension fund and leases it back long-term. Hidden reserves become liquidity, for example for growth or acquisitions. Institutional investors typically expect a yield of 3.5 to 5.5%.

In an asset-light exit, you sell only the OpCo – the operating business. Many buyers, private equity firms in particular, want to buy a company’s earning power but not finance the property along with it. Your family keeps the PropCo and continues to earn rental income, often under a long-term lease with the new owner.

5. Advantages and Disadvantages at a Glance

Dimension	Advantages for the business owner	Disadvantages & challenges
Liability & security	Complete ringfencing; real estate protected from operating risks and creditors.	Separation must be strictly observed; risk of veil piercing in the event of breaches of duty.
Tax & structure	Targeted control of distributions and depreciation; participation deduction available at holding level.	Strict arm’s-length test required; risk of hidden profit distributions and 35% withholding tax.
Succession & family	Ideal allocation: management to the successor, real assets to the other heirs.	Complex valuation between asset and earnings value; potential for intra-family rent disputes.
Financing & M&A	Separate, tailored credit structures; option of asset-light sale or sale-and-leaseback.	Banks often demand cross-collateral; 5-year blocking period after a hive-down.
Administration	Maximum business transparency; clear cost allocation in the operating business.	Double administrative burden (two financial statements, two tax returns, separate audits).

6. When We Recommend the Model – and When Not

An OpCo-PropCo structure is not an end in itself. It creates effort and only pays off if the benefits clearly outweigh it. In our experience, these situations speak in its favour:

• The property is a significant part of your wealth – and you want to protect it from the risks of day-to-day business.
• Your business carries real risk, for example liability exposure, warranties, volatile markets or dependence on a few key customers.
• Succession is coming up and not all heirs want to work in the business.
• A sale is conceivable in the medium term, for example to a strategic buyer or a private equity firm.
• You want to grow and use the property as an independent, bankable vehicle for additional financing.

We are just as open about when we advise against it:

• The property value is low. Below around CHF 1.5 to 2 million, the double costs for accounting, audit and administration usually eat up the benefits.
• A complete sale is imminent. If a sale is planned within five years, the blocking period prevents a tax-neutral hive-down.
• The business is only marginally profitable. If the OpCo cannot generate a market rent, tax adjustments or liquidity shortfalls follow.
• It is a special-purpose building. If the property is hardly usable outside your business (e.g. a chemical plant, heavy-duty foundations), banks often value the PropCo considerably lower.

Conclusion: Your Life’s Work Deserves a Structure That Protects It

The OpCo-PropCo structure turns a rigid concentration risk into a flexible instrument: it protects your real assets, creates tax planning room and enables a succession that is fair to the whole family. Its success, however, depends on the details. A sloppy lease, a missing tax ruling or a cross-collateral clause signed too lightly can quickly destroy the benefit.
