Swiss taxation is a system unique in the world, characterised by a distribution of competences between the Confederation, the 26 cantons and the approximately 2,148 municipalities. This three-tier structure offers considerable opportunities for companies that know how to navigate this complex tax landscape, but it also represents a significant challenge for those lacking the necessary expertise.
At AX-Fiduciaire, we support SMEs, start-ups and self-employed individuals in French-speaking Switzerland in all aspects of their taxation. From the tax return to legal tax optimisation, including VAT management and strategic advice, we put our expertise at the service of your financial performance.
The Swiss tax system: structure and particularities
Switzerland is distinguished by a pronounced fiscal federalism. Each institutional level levies its own taxes, creating intercantonal tax competition that benefits taxpayers. Understanding this architecture is essential for any effective tax strategy.
Direct federal tax (DFT)
The direct federal tax is levied by the Confederation uniformly across the entire Swiss territory. For legal entities (LLC, corporation), the rate is 8.5% on net profit. This tax is identical regardless of the canton or municipality of domicile of the company. It forms the basis of the tax burden to which cantonal and municipal taxes are added.
For natural persons (self-employed sole proprietors), the federal tax is progressive, with a maximum rate of 11.5%. Income from self-employment is integrated into the taxpayer's personal tax return, which can lead to higher taxation when other income is added.
Cantonal taxes
Each canton freely sets its own tax rates, which constitutes the heart of Swiss tax competition. The effective tax rate (combining federal, cantonal and municipal) can vary from less than 12% in the most attractive cantons (Zug, Nidwalden) to nearly 20% in certain configurations. In French-speaking Switzerland, the disparities are also significant: consult our detailed comparison of rates by canton.
Cantons have great freedom in defining their tax policy. Some have chosen low rates with a broad tax base, while others maintain higher rates but offer generous deductions. This diversity makes tax planning all the more important.
Municipal taxes
Municipalities levy a supplement to cantonal tax, generally expressed as additional centimes or a percentage of the basic cantonal tax. This supplement varies considerably from one municipality to another within the same canton. In Geneva, for example, the municipal rate can vary from 39 to 51 additional centimes depending on the municipality. The choice of company headquarters at the municipal level can therefore have a significant tax impact.
Main corporate taxes in Switzerland
Swiss companies are subject to several categories of taxes. Here is an overview of the main levies your company must face:
| Type of tax | Calculation basis | Collection | Particularities |
|---|---|---|---|
| Corporate income tax | Net profit | Federal + cantonal + municipal | Federal rate 8.5%, cantonal rates vary |
| Capital tax | Equity (shareholders' equity) | Cantonal + municipal | No federal tax, rates between 0.01% and 0.5% |
| VAT | Revenue | Federal only | Standard rate 8.1%, threshold CHF 100,000 |
| Anticipatory tax | Dividends, interest | Federal | 35%, refundable under conditions |
| Stamp duty | Issuance of securities, transactions | Federal | 1% issuance, 0.15%/0.3% negotiation |
| Withholding tax | Salaries of foreign employees | Cantonal | Scale according to personal situation |
Our tax advisory services
AX-Fiduciaire offers a full range of tax services to meet all the needs of companies in French-speaking Switzerland. Our approach combines technical rigour and strategic vision to guarantee you optimised and compliant taxation.
Tax returns for companies
The tax return is an annual obligation for every company registered in the commercial register. We handle the entire process: compilation of accounting documents, completion of official forms, calculation of tax provisions and filing within the deadlines imposed by the cantonal administration. Our in-depth knowledge of permitted deductions ensures that you do not pay more tax than necessary.
Legal tax optimisation
Tax optimisation involves using mechanisms provided by law to legally reduce the tax burden. We analyse your overall situation and identify available levers: choice of legal form, remuneration policy (salary vs. dividends), pension fund buybacks, accelerated depreciation, authorised provisions and choice of domicile. Every franc of tax saved is a franc that stays in your company to finance its growth.
VAT management
The value added tax concerns every company generating more than CHF 100,000 in annual revenue in Switzerland. We manage all your VAT obligations: registration with the FTA, periodic returns, choice between the effective method and flat-rate net tax debt method (NRDM), and optimisation of input tax recovery. For quick calculations, use our online VAT calculator.
Strategic tax planning
Beyond annual compliance, we offer medium and long-term tax planning. This includes anticipating the tax consequences of strategic decisions (acquisitions, restructurings, international expansion), implementing optimised structures and coordinating between personal and business taxation for directors and shareholders.
Assistance in case of tax audit
When a company is subject to a tax audit, we intervene on your behalf to prepare the required documentation, answer the administration's questions and, where appropriate, challenge unjustified reassessments. Our experience with cantonal and federal tax procedures is a decisive advantage in these situations.
Taxation according to legal form
The choice of legal form has a direct and significant impact on your taxation. It is essential to understand these differences well to make the right choice.
Sole proprietorship
A self-employed individual operating as a sole proprietor is personally taxed on the profit of their activity. The business income is added to their other income (spouse's salary, property income, etc.) and taxed at the marginal income tax rate. This rate can reach 40% or more for high incomes in certain cantons, making the legal form less advantageous above a certain profit threshold.
LLC and Corporation
LLCs and corporations are legal entities taxed separately from their shareholders. Profit is taxed at the corporate income tax rate, generally more favourable than the marginal rate for natural persons. However, dividend distributions are then taxed at the shareholder level, creating economic double taxation. This is mitigated by the partial taxation of dividends (generally 50% to 70% depending on the canton).
To determine which form is most advantageous in your specific situation, consult our sole proprietorship vs LLC comparison or our LLC vs corporation guide.
Intercantonal tax competition in French-speaking Switzerland
Switzerland is internationally known for its tax competition between cantons. Each canton seeks to attract companies by offering competitive tax rates and favourable framework conditions. This dynamic has led to significant reductions in tax rates in recent years, particularly following the tax reform and AHV financing (TRAF) that came into force in 2020.
In French-speaking Switzerland, effective tax rates for companies vary significantly:
| Canton | Effective tax rate (profit) | Trend |
|---|---|---|
| Geneva | 14.7% | Stable |
| Vaud | 13.9% | Stable |
| Valais | 14.6% | Stable |
| Fribourg | 13.7% | Stable |
| Neuchatel | 13.6% | Stable |
| Jura | 15.4% | Stable |

The most common tax mistakes in Switzerland
Over our years of experience, we regularly observe the same tax mistakes among companies. Identifying them is the first step to avoiding them:
- Not provisioning for taxes: forgetting to set aside tax provisions in the accounts leads to unpleasant surprises upon final assessment
- Ignoring possible deductions: many companies do not deduct all permitted charges (loss carry-forwards, depreciation, provisions for risks and charges)
- Wrong VAT method choice: opting for the effective method when the NRDM would be more advantageous (or vice versa) can cost several thousand francs per year
- Missing deadlines: late filing of the tax return incurs fines ranging from CHF 100 to CHF 10,000 and the loss of certain deductions
- Mixing private and business assets: insufficient separation complicates the tax return and can lead to reassessments
- Not planning dividend distributions: distributing without a strategy can result in excessive overall taxation for the shareholder
Swiss tax developments 2026
The year 2026 brings its share of tax developments that companies need to be aware of:
- OECD minimum taxation: Switzerland now applies a supplementary tax guaranteeing a minimum rate of 15% for large international groups, in accordance with Pillar 2 of the OECD that came into force in 2024
- VAT rates: the VAT rates in force since 2024 remain unchanged in 2026: 8.1% (standard), 2.6% (reduced), 3.8% (accommodation)
- Pillar 3a: the maximum deductible amount for employees is CHF 7,056 in 2026 (and CHF 35,280 for self-employed without a pension fund)
- Cantonal developments: several cantons are adjusting their rates and deductions, reinforcing the importance of active tax monitoring
