Executive Summary
General Requirements
- Arm’s length principles are derived from general anti-avoidance provisions in Article 58 of the Federal Direct Tax Act and Article 24 of the Tax Harmonization Act.
- A related party is defined by a 20% shareholding threshold in practice or the existence of a commercial or close personal relationship that influences transaction conditions.
- Compliance obligations to apply market prices apply to all taxpayers regardless of business size or specific transaction value thresholds.
- While not explicitly transposed into domestic law, the OECD Transfer Pricing Guidelines serve as the primary interpretative source for both federal and cantonal authorities.
Documentation Requirements
- Switzerland has no formal statutory requirement to prepare or maintain a Master File or a Local File.
- Taxpayers have a legal duty to cooperate and must provide sufficient documentation to justify their transfer pricing positions upon request during a tax assessment.
- Parent companies of international groups domiciled in Switzerland with a consolidated turnover exceeding CHF 900 million are required to file a Country-by-Country (CbC) Report.
- It is recommended that service relationships be documented in written contracts at the time they are established rather than waiting for a tax audit.
Results of Non-Compliance
- Failure to provide adequate documentation allows tax authorities to perform a discretionary estimate of the taxable base, which is rarely in the taxpayer’s favor.
- Obvious violations of the arm’s length principle may be classified as tax evasion, incurring penalties ranging from one-third to three times the evaded tax amount.
- Constructive dividends arising from primary adjustments trigger a 35% withholding tax, which may not be fully refundable under specific international beneficiary conditions.
- Non-compliance with CbC reporting requirements triggers administrative fines of CHF 200 per day, capped at a maximum of CHF 50,000.
Country Specific Information
- The Swiss Federal Tax Administration publishes annual safe harbor interest rates for intra-group loans in both Swiss francs and foreign currencies.
- Cantonal tax administrations have the authority to issue advance tax rulings covering both cantonal and federal corporate income taxes.
- Audit scrutiny is particularly high for transactions involving the relocation of business functions, transfers of intangible property, and dealings with low-tax jurisdictions.
- Taxpayers may be asked to provide translations of documentation into German, French, or Italian, though English is usually accepted by authorities.
