Valais Corporate & Capital Tax
Last updated: 09 Dec 2025
Valais (Wallis) Corporate & Capital Tax — Business Tax Overview
How corporate income tax and capital tax work in the Canton of Valais (Wallis) for companies: who is taxed, what is taxed, how rates are built up (including an overall corporate profit tax level in the high mid-teens in Sion), where Valais sits in the Swiss landscape, and where to dive deeper (profit tax, capital tax, rates, cases, calculator, and forms & deadlines).
Valais at a Glance
Position in the Swiss tax landscape
Valais is a higher mid-range corporate tax canton with clear, stable rules:
- In the cantonal capital Sion, ordinary companies typically face a combined (cantonal/communal plus federal) corporate income tax rate around the high mid-teens (≈17% on profit before tax), depending on year, commune and use of reliefs.
- Capital tax on equity is levied at moderate levels. For many profitable companies, cantonal mechanisms reduce the visible impact of capital tax so that the overall burden is dominated by profit tax.
- The canton’s economy combines tourism, energy (hydropower), agriculture and industry, with both French- and German-speaking areas and cross-border links into Italy and western Switzerland.
Key features for companies
| Tax types | Cantonal/communal profit tax, cantonal/communal capital tax, federal corporate income tax. |
| Taxpayers | Capital companies (SA/AG, Sàrl/GmbH), cooperatives, certain foundations and associations. |
| Profit tax base | Taxable profit derived from statutory accounts with tax adjustments and STAF instruments. |
| Capital tax base | Equity (including reserves and hidden equity) attributable to Valais, subject to specific reliefs. |
| STAF tools | Participation relief, patent box, additional R&D deductions and related measures. |
Who Is Taxed & On What?
- Resident companies. Companies with their statutory seat or effective place of management in Valais are subject to unlimited tax liability on their worldwide income and equity, with exemptions or credits for foreign permanent establishments and real estate under Swiss and treaty rules.
-
Nonresident entities. Nonresident companies are subject to
limited tax liability in Valais on profit and equity attributable to:
- Permanent establishments in Valais; and/or
- Valais-situs real estate or business assets.
- Legal forms in scope. The rules in this hub primarily address personnes morales / juristische Personen (SA/AG, Sàrl/GmbH, cooperatives). Partnerships and sole proprietors are taxed via personal income tax and are not the focus here.
- Tax period. For juristic persons, the tax period generally follows the financial year. Year-end changes or extended first years require coordination with the Valais tax administration.
Corporate Income Tax vs. Capital Tax
Valais, like other Swiss cantons, taxes companies both on their annual profit and on their equity. Understanding the distinction is key for planning relocations, investments and group structures in the canton.
| Aspect | Corporate income tax (profit tax) | Capital tax (equity tax) |
|---|---|---|
| Tax base | Taxable profit for the year (after adjustments, participation relief, STAF reliefs and loss offsets). | Equity attributable to Valais (share capital, reserves, hidden equity) valued under cantonal rules. |
| Economic focus | How much the company earns in or allocated to Valais. | How strongly the company is capitalised and where assets (especially real estate and participations) reside. |
| Key drivers | Business model, margins, transfer pricing, location of functions/risks, and use of patent box and R&D deductions. | Financing mix (equity vs debt), participations, IP, Valais real estate and long-term infrastructure assets (e.g. energy, tourism). |
| Interaction | Profit tax is calculated on taxable profit; STAF instruments can materially reduce the effective rate for qualifying companies. | Capital tax often operates as a minimum tax in low-profit or loss years; in profitable years, profit tax usually dominates the overall burden, and in some cases is credited against capital tax. |

For many Valais companies, the combined profit and capital tax burden is driven primarily by profit tax. But for holding structures, asset-heavy businesses (especially with real estate or energy assets) and early-stage entities, capital tax can still be a meaningful additional cost or binding minimum and should be modelled explicitly.
Indicative Rate Level & Competitiveness
Where do Valais rates sit?
While exact figures depend on tax year, commune, profit level and use of reliefs, Valais is typically viewed as:
- In the higher mid-range of Swiss effective corporate tax rates, with combined profit tax (including the federal layer) around the mid- to high-teens for standard operating companies.
- More expensive than Switzerland’s very lowest-tax cantons, but still internationally competitive, especially given Valais’ sector mix (tourism, energy, industry) and cost structure.
- Able to offer targeted solutions for holdings, IP and financing entities via STAF instruments, rulings and careful choice of commune.
For statutory parameters and trends over time, see the Rates page, which summarises simple rates, tax factors and minimum tax rules for Valais.
Quick modelling
To get a first feel for the combined tax burden (cantonal, communal and federal) on your company’s profit and equity in Valais:
- Use this hub’s Valais tax calculator for an approximate estimate; and
- Cross-check with official cantonal or federal calculators if you need a more precise view.
For restructurings, relocations or major investments, these tools are a starting point. A tailored model and, where appropriate, an advance tax ruling with the Valais tax office are usually the next step.
STAF, IP & Special Situations
Valais has implemented the Swiss corporate tax reform (STAF) and provides a toolbox of reliefs and instruments that can materially change the effective tax rate for qualifying companies, especially in IP-, R&D- or holding-heavy structures.
| Instrument | What it does | Where to look |
|---|---|---|
| Participation relief | Reduces the effective tax burden on qualifying dividends and capital gains from shareholdings in subsidiaries, significantly lowering profit tax for classic holding and group structures. | Explained in depth on the corporate tax page (participation income section). |
| Patent box | Allows qualifying IP income to be taxed at a reduced level, provided nexus and tracking conditions are met. This can make Valais attractive for IP-oriented operating companies with real substance. | Particularly relevant for IP companies and R&D structures described in the cases section. |
| R&D deductions | Provide additional deductions (beyond normal expenses) for qualifying R&D expenditure, lowering the profit tax base and effective rate. | Discussed in both the corporate tax and cases pages. |
| Capital tax relief | Certain assets (e.g. participations, IP) may benefit from privileged treatment for capital tax, and profit tax paid may reduce the residual capital tax burden. This is particularly relevant for holding and financing structures in Valais. | See capital tax and planning aspects on the rates page. |
These instruments are powerful but documentation-heavy. For material structures, Valais practice typically involves an advance ruling that coordinates cantonal and federal tax treatment and, where relevant, clarifies the interaction with other cantons and countries.
Compliance Workflow in Practice
For a typical Valais company (SA/AG or Sàrl/GmbH), the recurring tax workflow looks roughly like this:
| Step | What happens | Where to read more |
|---|---|---|
| 1. Year-end closing | Financial statements are prepared and approved; key tax-sensitive items (provisions, depreciation, transfer pricing, related-party transactions) are reviewed with Valais corporate and capital tax rules in mind. | Internal accounting, auditors, group tax. |
| 2. Tax return preparation | The Valais corporate tax return is prepared, including profit-to-tax reconciliation, capital tax base and any STAF instruments (patent box, additional R&D deduction). | Forms & deadlines |
| 3. Filing & payment | The return and financials are signed and filed; advance payments are reconciled; any remaining tax is paid within deadlines. Minimum tax and capital tax interactions are checked. | Forms & deadlines |
| 4. Assessment & follow-up | Combined cantonal/communal and federal assessments are issued. If needed, objections or appeals are filed within the stated period, and positions are coordinated with other cantons and jurisdictions. | Corporate & capital tax interactions: corporate tax, capital tax. |
| 5. Planning & rulings | For restructurings, IP or financing changes, relocations into or out of Valais or major investments, models are updated and rulings are prepared with Valais and federal authorities. | Cases & Valais Tax Service |
FAQs
Is Valais a high- or low-tax canton for companies?
Valais sits in the higher mid-range of Swiss corporate tax cantons. Its combined profit tax burden is higher than in Switzerland’s classic low-tax cantons, but still competitive by international standards. For businesses that are already rooted in the region (tourism, energy, industry), the overall mix of tax, infrastructure and labour market can be attractive.
Do I always pay both profit tax and capital tax in Valais?
Yes, for companies in scope, both are levied each year, but the relative weight varies. In profitable years, profit tax usually dominates and may significantly reduce the practical impact of capital tax; in low-profit or loss years, capital tax or a minimum tax can be the binding element. Special regimes and STAF instruments (such as patent box and R&D deductions) can change the mix for holdings and IP structures.
How important are advance tax rulings in Valais?
For routine annual filings, rulings are not usually needed. For structuring questions (holdings, IP, financing, relocations, major restructurings or large investments), rulings are common and provide valuable certainty, particularly where several cantons or countries are involved.
Can I manage Valais corporate tax from abroad?
Many groups manage Swiss corporate tax centrally and work with local advisors for Valais compliance and rulings. Returns can be prepared electronically and filed by post; communication with the tax office is possible via representatives. Substance, governance and documentation remain key, particularly for IP and financing structures that rely on Valais entities.
Where do I start if I am considering a move to Valais?
A typical sequence is: (1) high-level rate comparison and effective tax modelling for Valais vs. alternative cantons; (2) review of substance, functions and people; (3) structuring concept (legal form, holding / IP / finance set-up in or via Valais); and (4) pre-filing discussions and rulings with the Valais tax authorities. The Valais Tax Service is designed to support exactly this path.
