Grisons Corporate Income Tax
Last updated: 13 Dec 2025
Grisons Corporate Income Tax — Profit Tax Rules
How corporate income tax works in the Canton of Grisons (Graubünden): who is subject to profit tax, how the tax base is determined from accounting profit, how the uniform cantonal profit tax interacts with direct federal corporate income tax, and what to know about participation relief, patent box, R&D super-deduction and loss carryforwards.
Scope & Taxpayers
- Resident companies. Companies with statutory seat or effective place of management in Grisons are subject to unlimited tax liability on their worldwide income, subject to relief for foreign permanent establishments and immovable property under double tax treaties and intercantonal allocation rules.
- Nonresident entities. Nonresident companies are limited tax liable in Grisons if they have local business operations, a permanent establishment, or Grisons–situs real estate. Only the profits attributable to the Grisons nexus are taxed.
- Juristic persons only. The corporate income tax described here applies to juristische Personen (AG, GmbH, cooperative, certain foundations and associations). Partnerships and sole proprietors are taxed at shareholder/owner level under personal income tax.
- Uniform cantonal rate. For corporate income and capital tax, all municipalities in Grisons apply the same cantonal rates. Municipalities have no separate tax sovereignty for profit and capital tax; the canton levies uniform taxes plus a cantonal surcharge that is redistributed via the equalisation system.
- Tax period. The profit tax period for juristic persons generally follows the financial year. A change of year-end or an extended first business year must be coordinated with the Grisons tax administration.
Tax Base: From Accounting Profit to Taxable Profit
Grisons corporate income tax is levied on the company’s taxable profit, determined by starting from statutory financial statements (usually Swiss GAAP / OR; sometimes Swiss GAAP FER or IFRS for groups) and then making tax adjustments.
| Step | Description | Typical adjustments |
|---|---|---|
| 1. Accounting profit | Profit after tax per statutory financial statements for the relevant business year. | Profit as approved by the shareholders’ meeting, before appropriation of retained earnings. |
| 2. Add-backs | Non-deductible or partially deductible expenses are added back to profit. | Hidden profit distributions; excessive interest or royalties to related parties; non-business expenses; penalties; corporate income tax itself; provisions and value adjustments that are not commercially justified. |
| 3. Deductions | Items that are tax deductible but not expensed, or expensed differently, are deducted. | Tax-allowed depreciation exceeding accounting depreciation (within limits); specific provisions; participation relief; Grisons STAF instruments such as patent box and R&D super-deduction where applicable. |
| 4. Allocation & exemptions | Profits allocable to other cantons or foreign permanent establishments are exempt in Grisons under intercantonal and treaty rules. | Profit/loss attribution keys; separate determination of foreign PE income; treaty exemptions or credit methods. |
| 5. Taxable profit | Result after adjustments, before loss carryforwards and special reliefs. | Loss carryforwards of up to 7 years can be offset against current-year taxable profit (subject to general Swiss rules). |
The Grisons tax legislation and practice notes provide detailed guidance on depreciation, provisions, hidden equity, participation relief and STAF instruments. In practice, a clear reconciliation from accounting profit to taxable profit is expected as part of the corporate tax return.
Rates & Effective Burden
Cantonal profit tax & reliefs
The Grisons position itself as a competitive business location with ordinarily taxed companies paying 14.77% tax on net profit before taxes. This combined rate includes both cantonal profit tax and direct federal corporate income tax, and applies uniformly across all municipalities in the canton.
In the case of cantonal tax exemption (e.g. for qualifying new or substantially expanded activities), only the federal component remains, leading to an effective burden of about 7.83% of profit before tax for the exemption period (up to 10 years, subject to conditions and rulings).
The canton can grant up to 100% tax relief at cantonal level for up to ten years for companies that newly relocate to Grisons or significantly realign their operations. These exemptions are formalised via advance tax rulings and may be combined with federal regional policy relief in defined application areas.
For precise calculations of cantonal profit and capital tax, use the official Grisons tax calculator for legal persons (SofTax GR) and this hub’s Grisons tax calculator.
Federal corporate income tax
Switzerland levies direct federal corporate income tax at a flat rate of 8.5% on profit after tax. Because federal tax itself is deductible, this corresponds to an effective rate of about 7.8% on profit before tax nationwide.
In Grisons, the headline figure of 14.77% therefore corresponds to:
- Approx. 7.83% federal corporate income tax; plus
- Approx. 6.9% cantonal profit tax on profit before tax.
The Grisons tax calculator on this hub allows you to model combined cantonal and federal profit tax for a given level of taxable profit and to compare scenarios with and without STAF reliefs.
Where the patent box and R&D additional deduction are used at their maximum levels, Grisons indicates that the actual profit tax rate can be reduced to about 11.1% of net profit before taxes, subject to the relief cap described below.
Participation Relief & STAF Measures
Grisons follows federal rules for participation relief and has implemented the STAF toolkit with a patent box, an R&D excess deduction and a cantonal relief cap. In addition, the canton offers generous depreciation rules and location-specific tax relief.
| Mechanism | Overview | Typical planning aspects |
|---|---|---|
| Participation relief | Qualifying dividends and capital gains from shareholdings in subsidiaries are effectively subject to reduced taxation via a deduction calculated on the basis of net participation income relative to total profit (federal and Grisons rules). | Minimum shareholding thresholds (e.g. 10% or CHF 1m market value); holding period; treatment of write-downs and liquidation proceeds; interaction with foreign withholding tax, treaty relief and allocation between Grisons and other cantons. |
| Patent box | Income from qualifying intellectual property (patents and comparable rights), calculated in line with OECD nexus principles, may benefit from a reduced Grisons tax base. The canton allows up to 90% relief on qualifying net patent income, meaning only 10% of such income is included in the cantonal profit tax base. | Segregation of patent income and expenses; tracking of qualifying R&D costs; entry mechanism and treatment of pre-entry R&D; interaction with group transfer pricing and global minimum tax (Pillar 2) for larger groups. |
| R&D super-deduction | Grisons offers an R&D excess deduction of up to 50% on qualifying research and development expenses incurred in Switzerland, in addition to the ordinary expense deduction. This reduces the cantonal tax base for innovative companies. | Identifying qualifying R&D activities and costs; distinguishing Swiss vs. foreign R&D; aligning the additional 50% deduction with internal cost accounting and transfer pricing; documenting projects, personnel and cost categories. |
| Relief cap | Grisons applies a relief cap so that the combined impact of patent box and R&D excess deduction can reduce taxable profits by at most 55%. In other words, at least 45% of the relevant profit must remain fully taxed at ordinary rates. Participation relief operates in addition but is subject to general Swiss limitations. | For IP- and R&D-heavy structures, scenario modelling is essential: the cap can become binding and change the marginal value of additional R&D or IP migration to Grisons. Advance tax rulings are common before implementing major structures. |
| Location tax holidays | For new or substantially expanded activities, Grisons may grant cantonal tax relief of up to 100% for up to 10 years. This can reduce the combined profit tax burden to the federal component only (about 7.83% before tax), and may be combined with federal regional policy relief in certain municipalities. | Coordinating cantonal and federal relief, investment timing, substance build-up, job creation commitments and interaction with STAF instruments; documenting business plans in ruling requests. |
| Generous depreciation | Grisons highlights the possibility of immediate depreciation of up to 100% on certain investments in the year of acquisition or construction, as well as in the following year, within the framework of commercial justification and tax rules. | Planning investment cycles; smoothing the profit profile; interaction with patent box and R&D deduction; aligning depreciation with group reporting. |
For larger groups and IP-/R&D-intensive structures, the interaction of participation relief, patent box, R&D super-deduction, the 55% relief cap and potential tax holidays should be analysed in detail. Advance tax rulings are standard practice in Grisons for significant reorganisations and relocations.
Losses, Groups & Permanent Establishments
- Loss carryforwards. Tax losses can generally be carried forward for up to 7 years and offset against future taxable profits in Grisons, within the standard Swiss framework. Loss carryback is not available.
- Group situation. Switzerland has no fiscal unity or tax consolidation for ordinary corporate income tax. Each Grisons legal entity files its own return; group effects are managed via financing, transfer pricing, participation relief and, where relevant, the patent box and R&D deduction.
- Intercantonal allocation. Where a company has operations, real estate or permanent establishments in several cantons, profit and capital are allocated using generally accepted keys (e.g. payroll, assets, turnover) based on Grisons practice and federal jurisprudence.
- Foreign permanent establishments. Under many treaties, profits attributable to foreign permanent establishments are exempt in Switzerland with progression. Accurate attribution of profits and capital is essential to support the exemption and to avoid double taxation.
- Restructurings. Mergers, de-mergers, contributions in kind and migrations of seat can be tax neutral if Swiss conditions are met (continuity of business, carryover of hidden reserves, adequate consideration, etc.). Rulings are frequently used to secure treatment for Grisons and federal purposes, especially where several cantons or countries are involved.
Interaction with Capital Tax
Corporate income tax and capital tax are closely linked in Grisons. Profit tax is levied annually on taxable income, while capital tax is levied on the company’s equity. Both are assessed based on the same tax return for juristic persons.
- The ordinary capital tax rate for companies in Grisons is 0.488% of taxable equity. For companies with no business activities in Switzerland, a reduced capital tax rate of 0.01% applies.
- Grisons provides reductions for eligible equity relating to patents, participations and intercompany loans. This can significantly lower capital tax for holding, financing and IP structures, complementing the profit tax reliefs.
- Capital tax interacts with profit tax via the company’s capital structure: higher equity increases capital tax but may reduce thin-capitalisation risks and related-party interest recharacterisation for profit tax.
- For details on the capital tax base, reliefs and worked examples of combined profit and capital tax burdens, see the Grisons capital tax page and the combined tax calculator on this hub.

FAQs
How high is the corporate income tax rate in Grisons?
Ordinarily taxed companies in Grisons pay a combined corporate income tax rate of 14.77% of net profit before taxes. This figure already includes cantonal profit tax and direct federal corporate income tax. For companies that qualify for cantonal tax relief of up to 100% for a period (typically up to ten years), only the federal component of about 7.83% before tax remains during the relief period.
What STAF instruments does Grisons offer for companies?
Grisons offers a patent box with up to 90% relief on qualifying net patent income and an R&D excess deduction of up to 50% on qualifying Swiss R&D expenses, in addition to participation relief and generous depreciation rules. The combined effect of patent box and R&D deduction is limited by a relief cap, so that at most 55% of the relevant profit can be relieved. At full use of these instruments, the actual profit tax rate can drop to around 11.1% of net profit before taxes.
How does capital tax work for companies in Grisons?
Companies in Grisons pay capital tax on equity at an ordinary rate of 0.488% of taxable equity. For companies without business activities in Switzerland, a reduced rate of 0.01% applies. The canton grants reductions for eligible equity such as participations, patents and intercompany loans, which can significantly reduce capital tax for holding, financing and IP structures.
Are dividends from subsidiaries fully taxed in Grisons?
No. Qualifying participations benefit from participation relief at federal and cantonal level. This mechanism reduces the effective tax burden on net participation income (dividends and certain capital gains) using a formula that compares participation income to total profit. Where the conditions are met, the effective Grisons and federal tax on such dividends can fall to a low single-digit percentage.
How are losses treated for Grisons corporate income tax?
Tax losses can generally be carried forward for up to seven years and offset against future taxable profits. There is no loss carryback. In restructurings or changes of ownership, special Swiss rules may limit the use of losses; advance tax rulings are often used where material loss carryforwards are involved and Grisons is an important canton in the structure.
Can I get a ruling or tax holiday for a planned structure or relocation?
Yes. Grisons actively uses advance tax rulings and cantonal tax relief as part of its location policy. For new investments and substantial realignments, the canton may grant up to 100% cantonal tax relief for up to ten years, potentially combined with federal regional policy relief. Rulings are standard for such cases and typically cover profit and capital tax, use of patent box and R&D deduction, and allocation between Grisons and other cantons or countries.
