Corporate Group Taxation

Corporate Group Taxation and Tax Integration in Switzerland

The taxation applicable to corporate groups in Switzerland presents specificities that distinguish it from the regimes of other European countries. Unlike certain neighbouring states, Switzerland does not have a genuine tax integration regime allowing full consolidation of results. Nevertheless, the Swiss tax system offers various mechanisms to mitigate economic double taxation and optimise the tax burden of group structures. These mechanisms revolve around participation relief, tax-neutral restructurings and certain possibilities for loss offsetting between related entities. Understanding these mechanisms is a major issue for international groups established in Switzerland, in a context of international tax competition and constantly evolving OECD standards.

The Swiss Tax System and Its Particularities for Groups

The Swiss tax system is characterised by a federal structure with three levels of taxation: federal, cantonal and municipal. This architecture gives the Swiss tax regime a particular complexity for corporate groups that must deal with rules that sometimes differ by canton.

At the federal level, corporate income tax is levied at the flat rate of 8.5% (corresponding to an effective rate of 7.83% after tax deduction). For cantonal and municipal taxes, rates vary considerably from one canton to another, creating a form of internal tax competition that can influence groups' location decisions.

Unlike many European countries, Switzerland has not established a tax integration regime allowing full consolidation of results within a group. Each legal entity is considered a separate taxpayer and must file its own tax return.

Absence of a Genuine Consolidation Regime

The absence of a full tax consolidation system in Switzerland is a fundamental characteristic that groups must take into account in their planning. This Swiss particularity implies that each group company is taxed separately on its own profit, without the possibility of automatic compensation of profits and losses between entities of the same group.

Participation Relief: Cornerstone of Group Taxation

In the absence of a tax consolidation regime, the Swiss system has developed a central mechanism for groups: participation relief. This device constitutes the cornerstone of group taxation in Switzerland and aims to avoid the economic double taxation of profits generated within a group.

Participation relief is not a direct exemption but functions as a proportional reduction of profit tax. Its principle is to reduce the profit tax proportionally to the ratio between the net income from participations and the total net profit.

Conditions for Applying the Relief

To benefit from participation relief, two alternative conditions must be met:

• The company holds at least 10% of the share capital or share capital of another company
• The company holds participations with a market value of at least CHF 1 million

This mechanism applies both to dividends received and to capital gains realised on the disposal of participations, provided the latter have been held for at least one year and represent at least 10% of the capital of the company disposed of.

Participation relief constitutes a competitive advantage for Swiss holding companies, which can thereby receive dividends from their subsidiaries with a very reduced or virtually zero tax burden in certain configurations.

Loss Offsetting Mechanisms Between Related Entities

Although Switzerland does not have a tax integration regime as such, certain mechanisms nonetheless allow some of the effects of consolidation to be achieved, particularly in terms of loss offsetting between companies of the same group.

Loss Carryforward

In Swiss tax law, a company may carry forward its losses over the following seven financial years. Unlike other jurisdictions, Switzerland does not allow loss carryback, which limits groups' options for tax planning during economic downturns.

Transfer Values and Transfer Pricing

In the absence of tax integration, groups may resort to indirect mechanisms to optimise their overall tax burden:

• Intra-group service invoicing
• Intra-group loans with optimised interest rates
• Royalties for the use of intellectual property
• Centralisation of certain functions in specific entities

These mechanisms must comply with the arm's length principle and may be subject to in-depth scrutiny by Swiss tax authorities, which are particularly vigilant regarding transfer pricing.

Group Restructurings and Their Tax Treatment

Swiss law provides a specific framework allowing restructuring operations to be carried out with tax neutrality under certain conditions.

Tax-neutral Mergers and Demergers

For a merger to be considered tax-neutral, several conditions must be met:

• Tax liability in Switzerland must continue
• The tax-determinative values for profit tax are carried over
• The transaction must have an economic justification

Asset and Patrimony Transfers

Transfer of patrimony elements between companies of the same group can be carried out with tax neutrality when:

• The transfer concerns a business or a distinct part of a business
• The transfer concerns participations of at least 20% of the capital
• The tax-determinative values for profit tax are maintained

Current Challenges: BEPS and Swiss Tax Reform

The OECD's BEPS (Base Erosion and Profit Shifting) project has profoundly changed the approach to international taxation. Switzerland has adapted its tax legislation to meet these requirements, resulting in:

• Reinforced economic substance requirements
• Adoption of automatic exchange of tax information
• Implementation of BEPS minimum standards
• Modification of certain tax regimes considered non-compliant

The Swiss TRAF (Tax Reform and AHV Financing) reform has abolished certain special tax regimes while introducing new measures compatible with international standards:

• Patent box (reduced taxation of intellectual property income)
• Additional deductions for R&D expenses
• Notional interest deduction (NID) in certain cantons
