Geneva Corporate Income Tax
Last updated: 10 Dec 2025
Geneva Corporate Income Tax — Profit Tax Rules
How corporate income tax works in the Canton of Geneva: who is subject to profit tax, how the tax base is derived from accounting profit, how the cantonal/communal corporate income tax and the Swiss direct federal corporate income tax combine to an effective burden of around 14.7% on profit before tax, and how Geneva’s patent box (10% reduction) and 50% R&D super-deduction operate within the 70% relief cap. This page also covers participation relief, loss carryforwards, permanent establishments, step-up and the interaction with capital tax.
Scope & Taxpayers
- Resident companies. Companies with statutory seat or effective place of management in Geneva are subject to unlimited tax liability on their worldwide income, with relief for foreign permanent establishments and foreign immovable property under double tax treaties and intercantonal allocation rules.
- Nonresident entities. Nonresident companies are limited tax liable in Geneva if they have local business operations, a permanent establishment, or Geneva-situs real estate. Only the profits attributable to the Geneva nexus are taxed.
- Juristic persons only. The corporate income tax described here applies to personnes morales (AG/SA, GmbH/Sàrl, cooperatives, certain foundations and associations). Partnerships and sole proprietors are taxed at owner level under personal income tax.
- Tax period. The profit tax period for juristic persons generally follows the financial year. Changes of year-end or an extended first business year must be coordinated with the Geneva tax administration.
Tax Base: From Accounting Profit to Taxable Profit
Geneva corporate income tax is levied on the company’s taxable profit, determined by starting from statutory financial statements and then making tax adjustments in line with federal and cantonal rules.
| Step | Description | Typical adjustments |
|---|---|---|
| 1. Accounting profit | Profit after tax per statutory financial statements for the relevant business year (Swiss Code of Obligations; Swiss GAAP FER or IFRS for groups where required or chosen). | 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 profit and capital taxes; certain provisions and value adjustments. |
| 3. Deductions | Items that are tax deductible but not expensed, or expensed differently, are deducted. | Tax-allowed depreciation that exceeds accounting depreciation (within limits); specific provisions; participation relief; Geneva patent box reduction; additional 50% R&D deduction where applicable. |
| 4. Allocation & exemptions | Profits allocable to other cantons or foreign permanent establishments are exempt in Geneva under intercantonal and treaty rules, subject to progression. | Profit/loss attribution keys; separate determination of foreign PE income; treaty exemptions or foreign tax credit approaches. |
| 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 Loi sur l’imposition des personnes morales (LIPM) and associated practice notes, together with the official Geneva RFFA implementation guidance, provide detailed rules on depreciation, provisions, hidden equity, participation relief, patent box, the 50% R&D additional deduction and relief limitation. A clear reconciliation from accounting profit to taxable profit is expected as part of the corporate tax return. :contentReference[oaicite:0]{index=0}
Rates & Effective Burden
Cantonal & communal profit tax
Geneva levies a unified cantonal and communal corporate income tax on net profit (ICC). Special cantonal regimes for holding, mixed and domiciliary companies have been abolished as part of RFFA; all companies now face a broadly uniform rate. :contentReference[oaicite:1]{index=1}
- From 1 January 2020, the combined cantonal/communal corporate tax rate (excluding federal tax) was set so that the overall burden including direct federal tax was 13.99% on profit before tax, replacing the previous rate of about 24.2%. :contentReference[oaicite:2]{index=2}
- In the context of the OECD 15% minimum tax, Geneva has increased its effective corporate income tax rate (including federal tax) from roughly 14% to about 14.7% and abolished the separate municipal business tax, integrating it into corporate income tax so that the tax now counts fully as covered tax under the global minimum-tax rules. :contentReference[oaicite:3]{index=3}
- The result is a standard Geneva corporate income tax burden of around 14.7% on profit before tax for ordinary companies, with modest deviations possible depending on commune and church components.

Federal corporate income tax & combined rate
In addition to cantonal/communal profit tax, companies pay Swiss direct federal corporate income tax at a flat rate of 8.5% on profit after tax. Because federal tax is deductible, this corresponds to an effective rate of about 7.8% on profit before tax. :contentReference[oaicite:4]{index=4}
When cantonal/communal and federal components are combined, the ordinary corporate income tax burden for a standard Geneva company is currently around 14.7% on profit before tax. For large multinational groups within the scope of the 15% minimum tax, a supplementary tax may apply if the effective rate remains below 15%, but Geneva’s rate adjustment and abolition of municipal business tax reduce typical top-up amounts. :contentReference[oaicite:5]{index=5}

Participation Relief & STAF Measures
Geneva follows federal rules for participation relief and has implemented RFFA/STAF instruments including a patent box, a 50% R&D super-deduction and step-up possibilities for hidden reserves, all subject to the general Swiss relief limitation. :contentReference[oaicite:6]{index=6}
| Mechanism | Overview | Typical planning aspects |
|---|---|---|
| Participation relief | Qualifying dividends and capital gains from shareholdings in subsidiaries benefit from participation relief. Net participation income is compared to total profit to compute a deduction that significantly reduces the effective tax burden on qualifying investments. :contentReference[oaicite:7]{index=7} | Minimum shareholding thresholds (e.g. 10% or CHF 1 m market value); holding period; treatment of write-downs and liquidation proceeds; interaction with foreign withholding tax and treaty relief; alignment with group distribution policy and shareholder-level taxation in Geneva. |
| Patent box (10% reduction) | Geneva has implemented a patent box for qualifying patents and comparable rights. On request, net income from patents and comparable rights is taxed at cantonal/communal level with a 10% reduction of that net profit (i.e. only 90% of the net patent income is included in the ICC base). This is less aggressive than the 90% relief used by some other cantons but still provides targeted relief for IP-intensive businesses. :contentReference[oaicite:8]{index=8} | Identifying qualifying patents and comparable rights; nexus-compliant tracking of eligible R&D; calculating net patent income; shadow accounting for box entry (taxation of past R&D when entering the box); aligning patent box elections with global minimum-tax considerations. |
| R&D super-deduction (50%) | Geneva grants an additional deduction of up to 50% of qualifying R&D expenditure incurred in Switzerland, on top of the normal deduction of R&D costs. The additional deduction is calculated on eligible R&D personnel expenses plus a 35% uplift, and on 80% of R&D expenses invoiced by third parties in Switzerland. :contentReference[oaicite:9]{index=9} | Defining qualifying R&D projects; documenting Swiss R&D personnel; setting up cost-centre accounting to track eligible costs; balancing R&D super-deduction and patent box within the relief cap; coordinating with transfer pricing and group R&D hubs. |
| Relief cap (70%) | Under Swiss relief limitation rules, the combined effect of patent box, R&D super-deduction and step-up amortisations may not reduce the relevant taxable profit by more than 70%. At least 30% of the profit (before these reliefs and before loss offset, excluding net participation income) remains fully taxable at cantonal/communal level. Geneva has implemented this relief cap in its RFFA legislation. :contentReference[oaicite:10]{index=10} | Modelling the combined impact of participation income, patent box, R&D super-deduction and step-up amortisation; choosing which reliefs to claim in years when the 70% cap is binding; avoiding “wasted” relief; aligning with the 15% minimum tax and potential top-up. |
Geneva’s patent box (10% reduction) is modest compared to cantons offering up to 90% relief, but the 50% R&D super-deduction and step-up rules for hidden reserves can still meaningfully reduce the cantonal/communal tax base within the 70% relief cap, especially for R&D-heavy businesses moving functions or IP into the canton.
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 Geneva; loss carryback is not available. Relief instruments (patent box and R&D super-deduction) operate within the 70% cap and should not be used to create or increase loss carryforwards. :contentReference[oaicite:11]{index=11}
- Group situation. Switzerland has no full fiscal unity or group consolidation for ordinary corporate income tax. Each Geneva legal entity files its own return; group effects are managed via holding structures, intra-group financing, participation relief and, if desired, group VAT registration.
- 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 practice and jurisprudence. Geneva applies these nationwide principles, and intercantonal disputes are resolved under Swiss conflict rules.
- Foreign permanent establishments. Under many treaties, profits attributable to foreign permanent establishments are exempt in Switzerland with progression. Accurate attribution of profit and capital, consistent with OECD transfer-pricing standards, is essential to support the exemption at the Geneva and federal level.
- Restructurings & step-up. 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.). Geneva also offers step-up solutions for hidden reserves and goodwill on inbound relocations or when leaving special regimes, with amortisation of the step-up against the cantonal/communal profit tax base, subject to the 70% relief limitation. :contentReference[oaicite:12]{index=12}
- OECD minimum tax. For large multinational groups subject to the 15% global minimum tax, Geneva’s 14.7% rate and integrated municipal business tax mean that any top-up under Swiss or foreign GloBE rules is limited but still possible. Groups with substantial Geneva operations typically model the combined impact of patent box, R&D deduction and top-up early in their structuring. :contentReference[oaicite:13]{index=13}
Interaction with Capital Tax
Profit tax and capital tax are closely linked in Geneva. Profit tax is levied annually on taxable income, while capital tax is levied on the company’s equity. Both taxes are assessed based on the same corporate return for juristic persons. :contentReference[oaicite:14]{index=14}
- From 1 January 2020, the ordinary capital tax rate in Geneva is 0.4% of taxable equity for standard companies. A highly reduced rate of 0.001% (0.00001) applies to qualifying equity related to substantial participations, patents and intra-group loans, making Geneva attractive for holding and financing structures with large participation and IP portfolios. :contentReference[oaicite:15]{index=15}
- Municipal factors apply on top of the cantonal base rate; in the City of Geneva this leads to an effective ordinary capital tax burden of roughly 0.6% of equity for ordinary companies if no reduced-rate equity is present. :contentReference[oaicite:16]{index=16}
- Geneva allows imputation of profit tax against capital tax: corporate income tax is credited against capital tax so that, in profitable years, the ordinary capital tax can be partially or fully offset. In low-profit or loss years, capital tax can therefore act as a minimum tax on equity. :contentReference[oaicite:17]{index=17}
- The reduced capital tax rate for qualifying participations, patents and intra-group loans aligns the capital tax treatment with STAF measures on the profit side, encouraging the location of holding, IP and treasury centres in Geneva.
- The level and structure of equity influence the overall tax burden: higher equity increases capital tax (especially where profit is low) but reduces thin-capitalisation risk and the risk of recharacterising related-party debt as hidden equity for profit-tax purposes.

Compliance Snapshot
This guide focuses on the substantive rules for corporate income tax in Geneva. For procedural aspects — who files, which forms to use and which deadlines apply — see the dedicated Forms & deadlines page.
| Area | Key points |
|---|---|
| Filing | Annual corporate tax return for juristic persons using the Geneva forms and the GeTax software for capital companies, associations and foundations. The return covers cantonal/communal profit and capital tax and direct federal tax on profit. Electronic preparation is supported, but signed returns and financial statements remain binding. :contentReference[oaicite:18]{index=18} |
| Deadline | Filing deadlines are indicated on the corporate tax return invitation and typically fall several months after the end of the financial year. Extensions can usually be obtained upon timely online or written request; longer extensions or complex situations may require justification or the involvement of a professional representative. |
| Documentation | Signed financial statements; profit-to-tax reconciliation; annexes for participation relief, patent box and R&D deduction; capital tax calculation; intercantonal and international allocation schedules; transfer pricing documentation where relevant; copies of any rulings and step-up calculations. |
| Assessments & objections | A combined assessment is issued for cantonal, communal and federal taxes. Objection rights and deadlines are set out in the assessment notice. In complex structures, Geneva commonly works with advance rulings and pre-filing discussions rather than leaving key interpretive questions to the objection or appeal stage. :contentReference[oaicite:19]{index=19} |
FAQs
How high is the corporate income tax rate in Geneva?
Since the implementation of RFFA, Geneva has positioned itself as a mid-range corporate tax canton. From 2020, the combined corporate income tax rate for ordinary companies was about 13.99% on profit before tax. In the context of the OECD 15% minimum tax, Geneva has increased the effective corporate rate (including federal tax) to roughly 14.7% and abolished the separate municipal business tax, integrating it into corporate income tax. The current standard Geneva burden is therefore around 14.7% on profit before tax, with modest variations by commune and church status. :contentReference[oaicite:20]{index=20}
What is the difference between profit tax and capital tax in Geneva?
Profit tax (ICC plus federal tax) is charged on the company’s taxable income for the year, while capital tax is charged on the company’s equity (share capital, open and hidden reserves) at the balance sheet date. In Geneva, the ordinary capital tax rate is 0.4% of equity for standard companies, with a much lower rate of 0.001% for equity related to qualifying participations, patents and intra-group loans. Municipal factors apply on top of the cantonal rate, leading to an effective ordinary burden of roughly 0.6% of equity in the City of Geneva. Profit tax is credited against capital tax, so in profitable years capital tax often functions mainly as a minimum tax. :contentReference[oaicite:21]{index=21}
Are dividends from subsidiaries fully taxed in Geneva?
No. Qualifying participations benefit from participation relief at corporate level. Net participation income (dividends and certain capital gains) leads to a participation deduction that significantly reduces the effective corporate tax burden. At shareholder level, Geneva applies partial taxation for dividends from substantial participations, mitigating economic double taxation. :contentReference[oaicite:22]{index=22}
Does Geneva offer a patent box and R&D special deductions?
Yes. As part of RFFA, Geneva has implemented a patent box and a 50% R&D super-deduction. The patent box allows a 10% reduction of net income from qualifying patents and similar rights at cantonal/communal level, while the R&D super-deduction permits an additional deduction of up to 50% of qualifying Swiss R&D costs (based on R&D personnel expenses plus a 35% uplift and 80% of eligible third-party R&D). The combined effect of these measures and step-up amortisations is limited by a 70% relief cap, so at least 30% of the relevant profit remains fully taxable. :contentReference[oaicite:23]{index=23}
How are losses treated for Geneva 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. Relief from the patent box, R&D super-deduction and step-up amortisation is limited so that at least 30% of the relevant profit remains taxed; these reliefs cannot be used to generate or increase loss carryforwards beyond what is permitted under the relief cap. For restructurings or major changes in activity, advance rulings are common to secure the treatment of existing losses. :contentReference[oaicite:24]{index=24}
Can I get a ruling on a planned structure or transaction in Geneva?
Yes. Geneva offers advance tax rulings for a wide range of topics, including the application of the patent box and R&D super-deduction, the treatment of step-up on inbound migrations or regime changes, group financing structures, allocation of profit between Geneva and other cantons or countries, and the interaction of Geneva taxes with the 15% global minimum tax. A well-prepared ruling request can provide valuable certainty on corporate income tax and capital tax outcomes. :contentReference[oaicite:25]{index=25}
