Corporate Tax Residency in Switzerland
2026

A Practice Note setting out the situations where a company is subject to Swiss corporate income tax. It discusses when a non-Swiss resident company has a permanent establishment in Switzerland and how permanent establishments are taxed under Swiss law. It also describes how the right to tax a company's profit may be allocated under a double tax treaty if a company is tax resident in two jurisdictions. It does not cover the OECD/G20 Global Anti-Base Erosion Model Rules ("Pillar Two"), as Pillar Two does not create tax residence or a permanent establishment, nor does it allocate taxing rights under double tax treaties.

This Note describes the cases where resident and non-resident companies must pay Swiss corporate income tax. It also describes how the right to tax a company's profits may be allocated between different jurisdictions under a double tax treaty in case of double residence.

Basis of Taxation: Tax Residence

In broad terms Swiss corporate income tax applies to:

• Companies resident in Switzerland for tax purposes (which in general includes companies incorporated in Switzerland and foreign companies which are tax resident in Switzerland due to their place of effective management in Switzerland).
• Non-resident companies which have a permanent establishment (PE) in Switzerland (see Permanent Establishment).
• Non-resident companies which source income through a form of economic presence in Switzerland other than a PE (see Non-Resident Companies Without Permanent Establishment in Switzerland).

Tax Residence under Swiss Law

Under Swiss law, only corporate entities, such as corporations, associations and foundations (company or companies) are subject to corporate income taxation, whereas partnerships are generally treated as tax transparent (Article 49, Federal Direct Tax Act (FDTA)). A company is considered tax resident in Switzerland if any of the following applies:

• It is incorporated under Swiss law, that is, if the company's statutory seat (seat designated in the company's bylaws) is in Switzerland.
• Its place of effective management is located in Switzerland (see Place of Effective Management of Foreign Companies).

(Article 50, FDTA)

Place of Effective Management of Foreign Companies

Swiss tax law does not (apart from in case law) provide for a definition of "place of effective management". The place of effective management of a company is determined based on factual circumstances.

Generally, the following criteria are considered key to establish the place of effective management of a foreign company:

• The place of the company's actual economic centre of existence, that is, where the company's current business activity is predominantly managed to achieve the company's statutory purpose (i.e., the place from which the day-to-day activities are directed).
• The main place of decision making by directors and other persons who effectively play an important part in the decision-making process of a company (i.e. the place from which managerial decisions are taken).

Determination of Residence

Swiss tax law does not establish a general presumption of corporate residence. Instead, residence is determined on the basis of statutory connecting factors, namely the company’s legal seat or its place of effective management. The company's legal seat criterion for the purpose of determining its residency is considered to be evidenced through its commercial register entry. Where, however, residence at the place of effective management is claimed in deviation of the place of statutory seat of the company, the burden of proof lies with the claiming party (company or tax authorities).

A foreign incorporated company which is a potential Swiss tax resident company due to being effectively managed in Switzerland has a duty to cooperate with the tax authorities (Article 126, FDTA).

Taxation of Swiss Tax Resident Companies

Taxable Base

Swiss corporate income tax of a Swiss resident company is calculated on its total net income after taxes. The taxable net income is calculated in accordance with the profit and loss account results (according to Swiss bookkeeping standards) and considering certain tax adjustments under Swiss law. However, income attributable to real estate and permanent establishments located abroad is exempt from Swiss corporate income tax.

The cantons also levy an annual tax on the taxable capital of a Swiss resident company. This taxable capital corresponds to the sum of nominal capital, paid-in surplus, retained earnings, other equity reserves, and any deemed or hidden equity (according to Swiss thin capitalisation rules). In some cantons, the corporate income tax is creditable against the capital tax.
