Permanent establishment

Tax and legal implications for foreign companies operating in Switzerland

A permanent establishment (PE) in Switzerland can arise when a company carries out business activities through a fixed place of business or a dependent agent. This has important tax and legal consequences, in particular for foreign companies operating in Switzerland.

RSM Switzerland advises companies on permanent establishment risks, qualification and structuring, helping them assess their exposure and comply with Swiss tax and legal requirements.

What is a permanent establishment under Swiss law

Under Swiss tax law, in line with the OECD Model Tax Convention on Income and Capital, a permanent establishment represents a fixed place of business through which a company carries out a qualitatively or quantitatively significant part of its commercial or technical activities.

Fixed place of business in Switzerland

A permanent establishment may exist where a company has access to fixed facilities in Switzerland and uses them to carry out its activities. Ownership of the facilities is not required, provided the company can economically dispose of them, for example through a lease or rental agreement.

Typical examples include branches, factories, sales offices or permanent representations maintained for a sufficient period of time.

Qualitatively or quantitatively significant activity

An activity is considered qualitatively significant when it forms an integral part of the company’s core business, as opposed to purely auxiliary or administrative activities.

Quantitative significance is assessed based on the specific circumstances, taking into account the scale and importance of the activities performed in Switzerland.

Minor or ancillary activities generally do not give rise to a permanent establishment.

Economic dependence and agency permanent establishment

A permanent establishment may also arise where a dependent agent acts on behalf of a company and habitually exercises authority to negotiate or conclude contracts in the name of the enterprise.

Independent agents acting in the ordinary course of their business generally do not constitute a permanent establishment.

Tax and legal consequences of a permanent establishment

The existence of a permanent establishment in Switzerland generally results in Swiss corporate income tax exposure on profits attributable to the Swiss activities. This requires proper profit allocation, documentation and compliance with Swiss accounting and tax filing obligations.

In addition to tax implications, companies may face legal, accounting and registration requirements depending on the structure and activities carried out in Switzerland.

Branch offices as a form of permanent establishment

As an alternative to establishing a Swiss subsidiary, foreign companies may operate through a branch office in Switzerland.

A branch office is legally part of the foreign company but benefits from a certain organisational and financial autonomy. Branches can contract in their own name and may act as plaintiff or defendant before Swiss authorities.

Branch offices must be registered in the Swiss commercial register and are generally treated as Swiss companies for tax, accounting and reporting purposes. The appointment of an authorised representative domiciled in Switzerland is required.
