Group Company Taxation

Group Company Taxation and Fiscal Integration in Switzerland

The tax treatment applicable to groups of companies in Switzerland has specificities that distinguish it from regimes in other European countries. Unlike certain neighbouring states, Switzerland does not have a genuine fiscal integration regime allowing full consolidation of results. Nevertheless, the Swiss tax system offers various mechanisms that allow the economic double taxation to be mitigated and the tax burden of group structures to be optimised. These mechanisms are centred on the participation deduction, tax-neutral restructurings and certain possibilities for loss compensation between related entities. Understanding these mechanisms is a major issue for international groups established in Switzerland, in a context of international tax competition and constant evolution of OECD standards.

The Swiss Tax System and Its Specificities for Groups

The Swiss tax system is characterised by a federal three-tier taxation structure: federal, cantonal and municipal. This architecture gives the Swiss tax regime particular complexity for groups of companies that must cope with sometimes different rules depending on the canton.

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

Unlike many European countries, Switzerland has not introduced a fiscal 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 constitutes a fundamental characteristic that groups must take into account in their planning. This approach differs markedly from the fiscal integration regimes existing in France or Germany, where subsidiary results may be consolidated with those of the parent company.

This Swiss peculiarity means 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. However, alternative mechanisms have been developed to mitigate the effects of this absence of consolidation.

• Individual taxation of each legal entity
• No automatic compensation of profits and losses
• Need to resort to other optimisation mechanisms
• More complex tax planning for multinational groups

The Participation Deduction: Pillar of Group Taxation

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

The participation deduction is not a direct exemption but functions as a proportional reduction of the profit tax. Its principle is to reduce the profit tax in proportion to the ratio between the net income from participations and the total net profit.

Conditions for the Deduction

To benefit from the participation deduction, one of two alternative conditions must be met:

• The company holds at least 10% of the share capital or registered 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 upon 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 being sold.

The participation deduction constitutes a competitive advantage for Swiss holding companies which may thus receive dividends from their subsidiaries with a very reduced, or even quasi-zero, tax burden in certain configurations.

Loss Compensation Mechanisms between Related Entities

Although Switzerland does not have a fiscal integration regime as such, certain mechanisms nonetheless allow some of the effects of consolidation to be partially achieved, particularly regarding loss compensation between companies of the same group.

Loss Carry-Forward

Under Swiss tax law, a company may carry forward its losses over the following seven financial years. This carry-forward possibility constitutes a first level of optimisation for groups which may thus plan their activities taking this timeline into account.

Unlike other jurisdictions, Switzerland does not allow the carry-back of losses, which limits groups' options in terms of tax planning during economic downturns.

Value Transfers and Transfer Pricing

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

• Intragroup service billing
• Intragroup loans with optimised interest rates
• Royalties for the use of intellectual property
• Centralisation of certain functions in specific entities

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

Group Restructurings and Their Tax Treatment

Restructuring transactions constitute critical moments in the life of groups of companies. Swiss tax law provides a specific framework allowing, under certain conditions, these transactions to be carried out in tax neutrality.

Tax-Neutral Mergers and Spin-offs

The Federal Merger Act (LFus) governs these transactions from a legal standpoint, while the Federal Act on Direct Federal Tax (FITA) and the Federal Act on the Harmonisation of Direct Taxes (FHA) define their tax treatment.

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

• Subjection to tax in Switzerland must continue
• The determining values for corporate profit tax are carried over
• The transaction must have an economic justification

Asset and Patrimony Transfers

The transfer of assets between companies of the same group may be carried out in 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 determining values for profit tax are maintained

BEPS and International Standards

The OECD's BEPS (Base Erosion and Profit Shifting) project has profoundly modified the approach to international taxation. Switzerland, keen to maintain compliance with international standards, has adapted its tax legislation to meet these requirements. These changes result notably in:

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

The recent Swiss tax reform (TRAF) 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 expenditure, and financing deduction in certain cantons.
