Appenzell IR Corporate & Capital Tax Calculator
Last updated: 14 Dec 2025
Appenzell Innerrhoden Corporate & Capital Tax Calculator (Approximate)
Quick, approximate modelling of Appenzell Innerrhoden (AI) company tax: combine cantonal/communal profit tax, capital tax and Swiss federal corporate income tax on a given level of taxable profit and equity. Designed for educational planning — not as an official AI tax tool.
Appenzell Innerrhoden Tax Calculator (Approximate)
This calculator uses a simple effective-rate approach for AI (rather than reproducing every statutory detail), and assumes a standard setup without special regimes (no patent box, R&D super-deduction, notional interest deduction, special statuses, restructuring effects, etc.).
Results (Illustrative)
Approximate effective rate on profit: –
Figures are rounded and for illustration only. Minimum tax, detailed local nuances, reduced capital-tax bases, and intercantonal allocation are not modelled.
Assumptions & Methodology
| Parameter | Value used | Comment |
|---|---|---|
| Target combined effective profit tax burden (AI) | ~12.5% of profit before tax (all levels; standard) | Used as a planning anchor for Appenzell Innerrhoden. The tool shows the federal layer separately and models the AI cantonal/communal remainder. |
| Federal corporate income tax (effective) | ~7.83% of profit before tax | Derived from the official 8.5% rate on profit after tax (tax deductibility). |
| AI cantonal/communal profit tax (effective in this tool) | ~4.67% of profit before tax (standard) | Calculated as 12.5% minus 7.83%. A small local sensitivity factor is applied via the location selector. |
| Capital tax (simplified) | 0.20‰ of taxable equity (standard) | Applied to the equity base, then adjusted by the same local sensitivity factor. Reduced capital-tax bases (e.g., qualifying participations / IP / group loans) are not modelled. |
| Special regimes | Not modelled | Patent box, R&D deductions, notional interest deduction, special statuses and other instruments are excluded to keep the calculator transparent. |
This is not an official Appenzell Innerrhoden calculator. It is a deliberately simple approximation for planning and education. For filings, transactions, rulings or group structuring, rely on official tools and professional advice.
Worked Example
Assume a standard Appenzell Innerrhoden company with:
- Taxable profit before tax: CHF 1,000,000;
- Taxable equity (capital tax base): CHF 2,000,000;
- Location: “Standard corporate location” selection in this tool;
- No special regimes or loss carryforwards.
Under the calculator assumptions, very roughly:
- Cantonal/communal profit tax ≈ CHF 46,700
- Capital tax ≈ CHF 400
- Federal corporate income tax ≈ CHF 78,300
- Total tax ≈ CHF 125,400
- Effective rate on profit ≈ 12.5%
These figures are rounded and illustrative. Real outcomes depend on the company profile, reliefs (patent box/R&D), participation relief interactions, and any intercantonal or international allocation.
Official Tools & When to Get Advice
| Tool / resource | Use case | Comment |
|---|---|---|
| AI official tax resources | Confirm current parameters, municipal practice and official calculation logic. | Use cantonal resources for the latest official rates and any municipality-specific provisions before making decisions or filing. |
| Federal tax calculator environment (ESTV/AFC) | Benchmark corporate tax burdens across cantons. | Helpful for comparisons and sanity checks. |

FAQs
How accurate is this Appenzell Innerrhoden calculator?
It is intentionally simplified. It uses an approximate effective AI profit-tax burden as a planning anchor, adds a simplified capital tax, and shows the federal layer separately. It does not model minimum tax, detailed local nuances, reduced capital-tax bases, loss carryforwards, special regimes, or intercantonal/international allocation.
Can I use this output for my financial statements?
No. Financial statements, budgets and tax provisions should be based on detailed models or official calculators aligned with the latest law and practice. This tool is for education and high-level planning only.
Does this calculator handle intercantonal or international allocation?
No. It assumes a company taxed entirely in Appenzell Innerrhoden. If you have permanent establishments, properties or functions in other cantons or countries, you will need an allocation model and, often, local advice.
Can Sesch TaxRep help refine these numbers?
Yes. We can build a company-specific AI tax model, prepare or review corporate tax returns, and assist with rulings and structuring. See the Appenzell IR service links above or use the general contact form on taxrep.us.
