How to Use This Cases Page
This page does not reproduce specific court decisions or official case numbers. Instead, it translates typical Appenzell Innerrhoden practice into illustrative case studies that show how:
- Corporate income tax and capital tax interact;
- Intercantonal allocation and international rules are applied; and
- Planning and compliance issues arise in day-to-day situations.
Each case summarises the facts, key tax questions and a pragmatic outcome using Appenzell Innerrhoden practice as a reference point. In real engagements, outcomes depend on detailed facts and, frequently, on advance tax rulings.
Appenzell Innerrhoden is one of Switzerland’s smallest cantons. Many practical questions involve simple allocation facts, the treatment of small-entity structures and clear documentation with local offices. The cases below are therefore pitched to reflect these themes.
Case 1 – Relocating a Holding Company to Appenzell Innerrhoden
Facts
- A group holding company resident in another Swiss canton considers moving its statutory seat to Appenzell Innerrhoden.
- The company mainly holds participations in operating subsidiaries and some intra-group loans.
- There are hidden reserves in participations and in foreign-currency loans.
Key tax questions
- Does the seat migration trigger taxation of hidden reserves in the departure canton?
- How is equity allocated between the departure canton and Appenzell IR for capital tax?
- What income and capital tax profile applies post-migration?
Practical outcome
- Under intercantonal rules, the departure canton typically taxes hidden reserves to the extent they are allocated to that canton. A careful opening/closing balance sheet is required.
- In Appenzell Innerrhoden, the holding company’s equity becomes part of the local capital tax base; given the canton’s simple allocation rules and generally moderate rates, modelling often shows a smooth transition with clear documentation.
-
Advance rulings are used to:
- Confirm neutrality or managed taxation of the migration; and
- Secure the post-migration treatment of participation relief and financing functions under local practice.
Lesson: Even straightforward seat migrations benefit from early planning and clear opening/closing balance sheets. In Appenzell IR, pragmatic documentation and dialogue with the tax office help ensure an efficient outcome.
Case 2 – Start-up with Losses & Minimum Tax
Facts
- A tech start-up (AG) in Appenzell Innerrhoden is loss-making for several years.
- The company is equity-financed and incurs significant R&D expenses.
- Intellectual property is developed in-house, with future commercial plans.
Key tax questions
- How are losses reported and preserved for future use?
- When does the minimum tax become relevant?
- Should management prepare for STAF instruments (e.g., patent box) before profitability?
Practical outcome
- The start-up files annual tax returns even in loss years to preserve loss carryforwards and document R&D activities.
- Once beyond the initial years, a cantonal/communal minimum tax applies each year, despite losses.
- Documenting IP and R&D early supports later STAF elections and enhances investor confidence.
Lesson: Consistent filing and R&D documentation are assets. Loss preservation and early preparation for STAF instruments improve long-term tax efficiency.
Case 3 – IP & R&D Using STAF Instruments
Facts
- An established group relocates its Swiss IP management and key R&D functions to Appenzell IR.
- The group centralises patents and trademarks locally and recharges licence fees.
- Some R&D work is outsourced to foreign affiliates under arm’s length arrangements.
Key tax questions
- How to qualify for patent box and R&D deductions?
- How to apply the nexus approach to IP income and related expenses?
- How does capital tax treat IP-rich balance sheets?
Practical outcome
- The IP/R&D company tracks income and costs by project/family of patents and prepares robust transfer pricing documentation aligned with OECD principles.
- An advance ruling from Appenzell IR confirms the patent box election and agrees acceptable allocation methodologies.
- Capital tax implications of IP valuation step-ups are modelled, with potential relief for qualifying assets incorporated.
Lesson: STAF requires detailed documentation and credible substance. Even in smaller cantons like Appenzell IR, compliance and tracking underpin favourable outcomes.
Case 4 – Real Estate Company with Cross-Cantonal Property
Facts
- An Appenzell IR real estate company owns commercial property across multiple cantons.
- Rental yields differ by location and financing is a mix of bank debt and shareholder loans.
- Profit and capital allocations vary significantly by property location.
Key tax questions
- How are profit and capital allocated between Appenzell IR and other cantons?
- How are interest and debt allocations treated?
- Can shareholder loans be reclassified as hidden equity?
Practical outcome
- The company applies standard allocation models: profit by rental income drivers, and capital by market values and related financing metrics.
- Appenzell IR taxes only the portion of income and equity attributable to local property and head office functions.
- Excess shareholder loans are scrutinised for thin capitalisation effects, potentially increasing capital tax base and interest nondeductibility.
Lesson: Allocation is essential. Clear allocation models and documentation minimise disputes across cantonal jurisdictions.
Case 5 – Group Financing & Thin Capitalisation
Facts
- An Appenzell IR finance company acts as group treasury, lending to foreign subsidiaries.
- Funding is a mix of equity and related-party loans; some borrowers post small operating losses.
- Interest margins are modest, raising potential thin capital concerns.
Key tax questions
- Is the finance company adequately capitalised under Swiss thin capitalisation guidelines?
- Are intercompany interest rates arm’s length?
- How should profit and equity be allocated between Appenzell IR and foreign branches?
Practical outcome
- The group benchmarks intercompany interest using Swiss safe-harbour indicators and maintains transfer pricing documentation.
- Appenzell IR reviews leverage; excess debt may be treated as hidden equity, increasing capital tax base and disallowing interest deductions.
- Cross-border lending implications (treaties, withholding) are analysed and adjustments made before ruling requests.
Lesson: Group financing interacts with both profit and capital tax. Coherent leverage, pricing and documentation underpin defensible positions.
Rulings, Audits & Practice Points
| Area | What Appenzell IR Typically Looks At | Practical Tips |
|---|---|---|
| Advance tax rulings | Structures with holding, financing or IP functions; major reorganisations; use of STAF instruments; cross-cantonal allocation issues. | Prepare fact-rich ruling requests; attach structure charts, forecasts and calculations; align with federal and other cantonal positions; confirm local allocation methodology. |
