Starting a Business in Switzerland — Einzelfirma Guide
Switzerland is one of the most popular countries in Europe for self-employment. The sole proprietorship — known locally as Einzelfirma (German), entreprise individuelle (French), or ditta individuale (Italian) — is the simplest and most common business structure in the country.
Legal Structure and Characteristics
A sole proprietorship in Switzerland is not a separate legal entity. The business owner and the business are considered one and the same under Swiss law. This means the owner has unlimited personal liability for all business debts and obligations — there is no asset protection between private and business property.
Despite the liability risk, the Einzelfirma remains the preferred business form for freelancers, consultants, tradespeople, and small service providers across Switzerland. The primary reasons are straightforward: zero minimum capital, minimal bureaucracy, and full decision-making autonomy.
Any natural person can operate a sole proprietorship; the business name must be formed from the owner's surname (Code of Obligations, Art. 945). Swiss citizenship is not required, but foreign nationals need a residence permit that allows self-employment.
Registration Process
Commercial Registry (Handelsregister)
Registration in the Swiss Commercial Registry (Handelsregister) becomes mandatory once revenue in the previous business year reaches CHF 100,000 (Code of Obligations, Art. 931; liberal professions without a commercially run business are exempt). Below this threshold, registration is voluntary but recommended, as it provides legal name protection and increases credibility with clients and suppliers.
Important: Even without Handelsregister registration, a sole proprietorship exists from the moment business activity begins. Revenue below CHF 100,000 does not exempt the owner from tax or social security obligations.
Registration Costs
Commercial Registry fees are not set by the cantons: they are defined uniformly for all of Switzerland by the federal Ordinance on Commercial Register Fees (GebV-HReg). The exact amount depends on the entries required for your business.
Step-by-Step Timeline
Choose a business name, define your activity, and prepare required documents (ID, proof of address, description of business activity).
Contact your cantonal compensation office (Ausgleichskasse) to register as self-employed. You will need to provide evidence of independent business activity — typically client contracts, invoices, or a business plan. Processing takes 5–15 business days.
Submit your application to the cantonal Handelsregister (if required or desired). Online applications are available in most cantons. Approval takes 3–10 business days.
Most Swiss banks require a registered business name for a dedicated account. Minimum opening deposits range from CHF 0 (neobanks) to CHF 1,000 (traditional banks). Some banks charge monthly fees of CHF 5–15 for business accounts.
Register with the Federal Tax Administration (FTA/ESTV) if your annual revenue exceeds or is expected to exceed CHF 100,000. VAT registration can also be done voluntarily below this threshold.
Tax Obligations
Income Tax
Sole proprietors in Switzerland do not pay corporate tax. Business income is added directly to the owner's personal income and taxed at the applicable federal, cantonal, and municipal rates. Effective income tax rates vary substantially between cantons — from roughly 22% in Zug to over 44% in Geneva for high earners.
Business expenses, depreciation, and provisions can be deducted from revenue. Swiss sole proprietors are required to keep proper bookkeeping records if their annual revenue exceeds CHF 500,000. Below this threshold, simplified accounts (revenue and expense tracking) are sufficient.
Value-Added Tax (MWST/TVA/IVA)
VAT registration is mandatory for sole proprietorships generating more than CHF 100,000 in annual revenue. Once registered, the standard VAT rate is 8.1%, with reduced rates of 2.6% (daily necessities) and 3.8% (accommodation services).
Businesses below the CHF 100,000 threshold can register voluntarily, which may be advantageous for B2B service providers who want to reclaim input VAT on purchases. VAT returns are typically filed quarterly, with annual settlement.
Withholding Tax and Other Levies
Sole proprietors are not subject to withholding tax on their business income (unlike employees). However, they are responsible for making provisional tax payments throughout the year. Most cantons send provisional tax bills in quarterly installments.
Social Security Contributions
Self-employed individuals in Switzerland must register with the cantonal compensation office (Ausgleichskasse) and contribute to several mandatory social insurance schemes:
| Insurance | Contribution Rate | Notes |
|---|---|---|
| AHV (Old-age insurance) | 8.1% of net income | Minimum CHF 530/year |
| IV (Disability insurance) | 1.4% of net income | Included in AHV billing |
| EO (Income replacement) | 0.5% of net income | Covers military/maternity leave |
| Total mandatory | 10.0% of net income | Declining scale for income below CHF 60,500 |
Declining contribution scale: For annual net income below CHF 60,500, the AHV/IV/EO rate decreases on a sliding scale; below CHF 10,100 the minimum contribution of CHF 530 per year applies (as of 1 January 2026). This benefits part-time self-employed individuals and those in their first year of business.
Unlike employees, sole proprietors in Switzerland have no mandatory unemployment insurance (ALV) contributions and cannot claim unemployment benefits if the business fails. Accident insurance (UVG) is also not mandatory for sole proprietors without employees, though it is strongly recommended.
Pension Planning (2nd and 3rd Pillar)
Self-employed individuals without employees are not required to join a pension fund (2nd pillar / BVG). However, they can voluntarily join the BVG or contribute to the tax-privileged 3rd pillar (Pillar 3a), with maximum annual contributions of CHF 36,288 (2025 figure for self-employed without BVG). These contributions are fully tax-deductible.
Invoicing and Payment Standards
Swiss sole proprietors are required to issue invoices that comply with Swiss law. Since October 2022, the QR-bill (QR-Rechnung) has been the mandatory payment slip format in Switzerland, replacing the old orange and red payment slips (ESR/ES).
A compliant Swiss invoice must include the business name and address, a unique invoice number, the date of delivery or service, a detailed description of goods or services, the amount in CHF, and — if VAT-registered — the VAT number (CHE format) and applicable VAT rate.
A QR-IBAN (clearing number range 30000–31999) enables QR-bills with a structured QR reference and automated payment matching; a regular IBAN works for QR-bills without a reference or with a Creditor Reference. Setting up QR-bill invoicing typically takes 15–30 minutes with modern invoicing tools.
Common Costs in the First Year
Starting a sole proprietorship in Switzerland is relatively affordable compared to forming a GmbH (CHF 20,000 minimum capital) or AG (CHF 100,000). Typical first-year costs break down as follows:
| Expense | Cost (CHF) | Frequency |
|---|---|---|
| Commercial Registry registration | Federal fee (GebV-HReg) | One-time |
| Business bank account setup | 0–100 | One-time |
| Accounting software | 0–600 | Annual |
| Business liability insurance | 300–1,200 | Annual |
| AHV/IV/EO (minimum) | 530 | Annual |
| Health insurance supplement | 0–500 | Annual |
| Domain and website | 100–500 | Annual |
| Professional association membership | 100–400 | Annual |
In total, a Swiss sole proprietor can expect to spend between CHF 1,200 and CHF 3,800 in the first year on administrative and mandatory costs — excluding rent, equipment, and materials specific to their trade. This makes the Einzelfirma the most cost-effective business structure in Switzerland.

Converting to a GmbH or AG
Many Swiss sole proprietors eventually convert their Einzelfirma to a GmbH (Gesellschaft mit beschränkter Haftung) as their business grows. The most common triggers are: annual revenue exceeding CHF 300,000–500,000, the desire for liability protection, or taking on business partners.
The conversion process takes approximately 4–8 weeks and involves notarization costs of CHF 1,500–3,000, plus the GmbH's minimum share capital of CHF 20,000. Existing contracts and client relationships can be transferred to the new entity.
Frequently Asked Questions
Can I run a sole proprietorship while employed full-time?
Yes, this is very common in Switzerland. Around 30% of sole proprietorships are operated as side businesses. Your employer should be informed if your contract contains a non-compete or secondary employment clause. Social security contributions apply to your self-employed income in addition to your employment contributions.
Do I need a separate business bank account?
It is not legally required but strongly recommended. Mixing personal and business finances makes bookkeeping difficult and can create issues during tax audits. Most Swiss banks offer business accounts for sole proprietors starting at CHF 5–15 per month.
What happens if my sole proprietorship fails?
Since there is no separation between private and business assets, you are personally responsible for all outstanding debts. There is no access to unemployment benefits (ALV). If debts become unmanageable, personal bankruptcy proceedings may apply. This is the primary reason many growing businesses convert to a GmbH for liability protection.
Can foreigners start a sole proprietorship in Switzerland?
Yes, but the residence permit must allow self-employment. Holders of a C permit (permanent residence) can register a sole proprietorship; for B permits it depends on the permit conditions. EU/EFTA citizens benefit from bilateral agreements that simplify the process. Non-EU citizens typically need to demonstrate economic benefit to Switzerland.
