Bogus self-employment (Scheinselbstständigkeit) in Switzerland is one of the biggest risks for freelancers and clients alike. The AHV (Swiss old-age and survivors' insurance) increasingly scrutinises whether a collaboration is genuinely based on self-employment — or on a hidden employment relationship. If the AHV detects bogus self-employment, retroactive payments of five- to six-figure CHF amounts loom. This guide shows you how to prove genuine entrepreneurship, protect yourself, and cleanly satisfy the AHV criteria.

What is bogus self-employment in Switzerland?

Bogus self-employment occurs when a person formally appears as self-employed but is in fact integrated into a company like an employee. The AHV calls this "dependent employment under the guise of self-employment."

Swiss law does not define bogus self-employment as its own statutory norm. Instead, the compensation fund (Ausgleichskasse) assesses on a case-by-case basis whether a person is classified as self-employed (under AHVG Art. 2–3) or as employed. The latter means: both employer and employee owe the AHV contributions.

The consequence: if the person was treated as self-employed for years, the AHV claims the contributions back — typically retroactively for up to 5 years. That can quickly amount to CHF 50,000.00 or more.

Why the AHV fights bogus self-employment

The AHV loses millions when employers hire freelancers who are actually employees. In a regular employment relationship, the employer pays half of the social security contributions — for self-employed persons, this does not apply. The AHV therefore acts consistently and checks new registrations, during audits, and in cases of suspicion.

Important: A written agreement that speaks of self-employment does not change the AHV's factual assessment. The so-called economic substance of the activity is what counts.

The 5 AHV criteria: when are you considered self-employed?

The AHV examines various indicators to determine self-employment. No single criterion alone is decisive — the overall picture counts. The most important criteria derive from AHVG Art. 2 para. 3 and the practice of the cantonal compensation funds.

1. Personal dependence

Are you bound by instructions from the client? If someone tells you when, how, and where to work, that strongly suggests an employment relationship. Self-employed persons deliver their work according to their own plan, within agreed deadlines.

Example: A developer who must be present in the client's office every morning at 9 a.m. and works on their tickets is personally dependent. A developer who works from home, chooses their own tools, and merely meets deadlines is free.

2. Economic dependence

How large is your share of the client's revenue? If more than 50–60% of your income comes from a single source, the AHV becomes alert. With multiple clients and your own customer base, the risk drops drastically.

3. Integration into the operation

Are you embedded in the client's hierarchy, team meetings, and processes? Do you have a business card with the company logo, an @company.ch email address, or access to the internal system? The deeper the integration, the more likely it points to bogus self-employment in Switzerland.

4. Entrepreneurial risk

Do you bear your own risk? Self-employed persons invest in their infrastructure, have their own equipment, pay for their own software, and bear the risk for unforeseen losses. Employees have no entrepreneurial risk — the employer provides everything.

5. Multiple clients

The clearest signal: do you have several clients? The AHV generally requires at least 2 to 3 clients to recognise self-employment. The AHV criteria on ahv.ch recommend that no single client accounts for more than half of revenue.

Risks for freelancers: retroactive payments and consequences

Freelancers who fall victim to bogus self-employment in Switzerland bear the full financial risk. The AHV claims contributions that the employer and employee should each have borne half of. That means: the freelancer suddenly pays the full contribution rate — not just the half they would have owed as a self-employed person anyway.

On top of that come the employer contributions that the client should have paid. If the client does not pay (e.g. insolvency, dispute), the AHV can hold the freelancer liable. In practice, freelancers often end up bearing a large share of the retroactive claim.

The story of Thomas

Thomas is a graphic designer in Zurich. For three years he had a major regular client who generated about 70% of his income. The remaining 30% came from small projects. Thomas sometimes worked in the client's office, used their Adobe licenses, and received instruction-like directives.

During an AHV audit, the case was reviewed. The AHV concluded: the main client was in fact an employer. Thomas received a retroactive claim of CHF 12,400.00 for three years of AHV contributions — plus interest. The "employer" was also held liable.

Thomas had to repay the amount in instalments. His reputation in the industry suffered because the former client was upset. He lost the client and needed months to acquire new projects.

What freelancers risk

• Retroactive AHV contributions: up to 5 years retroactively, often CHF 10,000.00 to CHF 50,000.00 depending on income
• Interest: the AHV charges interest on retroactive payments
• Loss of status: you must re-register as an employee or change your structure
• Tax risk: the change of status also alters the tax treatment
• Reputational risk: clients become upset when the AHV imposes employer contributions on them

Tax consequences

When self-employment is reclassified as an employment relationship, tax effects also arise. The FTA (Federal Tax Administration) checks whether income must be re-declared as employee income. Anyone who charged VAT (Swiss: MWST) despite not being self-employed risks a reclaim of VAT deductions.

Tip: When you register as self-employed with the AHV, have the compensation fund formally review and confirm your status. An AHV certificate is your best protection.

Risks for clients: why companies must be cautious

Companies that work with freelancers bear a massive risk. The AHV can classify them as employers — with all the obligations that entails.

Retroactive employer contributions

If the AHV decides that a freelancer is actually an employee, the company must pay the employer contributions retroactively: AHV/IV/EO, unemployment insurance, pension fund, accident insurance. The retroactive payment can amount to CHF 20,000.00 to CHF 80,000.00 per person per year.

Wage fringe costs and obligations

In cases of genuine bogus self-employment, the following additionally apply:

• Holiday compensation (typically 8.33% of gross salary)
• Public holiday compensation
• 13th-month salary, if customary in the industry
• Continued salary payment during illness (under the Swiss Code of Obligations, OR)
• Participation in the pension fund (BVG)

Sample calculation

A company employs a "freelancer" for CHF 80,000.00 per year. If the AHV takes action, employer contributions of approx. 15–20% are added:

Over 5 years retroactively: CHF 97,500.00. Plus interest. Plus fines.

Reputational and compliance risk

Large companies have compliance guidelines. If a freelancer relationship is classified as bogus self-employment, internal audits and reputational damage loom. It is therefore important to document clearly in the contract design that the collaboration is based on self-employment.

Helpful: structure contracts for freelancers correctly.

Avoiding bogus self-employment: 7 measures for genuine self-employment

Measure 1: Acquire multiple clients

Aim for at least 3 to 4 active clients. No client should account for more than 50% of your revenue. The broader your base, the clearer your self-employment.

The story of Marco: Marco was a web developer in Bern. For two years he had only one client. The AHV announced a review. Marco acquired three more clients within three months. Today his revenue is spread across four clients, none generating more than 35%. His risk of bogus self-employment in Switzerland is close to zero.

Measure 2: Own infrastructure

Use your own software, your own laptop, your own Adobe license, your own office. Do not bill clients for the client's equipment. Registering a sole proprietorship in Switzerland (Swiss: Einzelfirma) signals seriousness.

Measure 3: Clear contracts

Conclude work contracts (Werkvertrag), not employment contracts. A work contract (OR Art. 469) governs the delivery of a specific service at a fixed price. Writing quotes is part of a professional approach. For details on the work contract, see the article on the work contract in Switzerland.

Measure 4: Obtain an AHV certificate

Have your self-employment formally confirmed by the cantonal compensation fund. It costs nothing but creates clarity. Present the certificate to every new client.

The story of Sarah

Sarah is a management consultant in Basel. She knew from the start that she had to document her self-employment. For every new project, she submits a current AHV certificate to the client. During an AHV audit of her main client, the certificate was in the file. The AHV confirmed self-employment immediately — no retroactive payment risk.

Sarah also formulated her quotes in writing from the start, with clear service descriptions and fixed lump-sum prices. She uses a professional setup: her own invoicing software, her own company logo, her own email address with her own domain name. She registered her sole proprietorship (Swiss: Einzelfirma) after brief preparation and entered it in the commercial register.

Measure 5: Own prices and quotes

Do not bill by the hour like an employee. Set fixed project prices, submit quotes, and negotiate independently. The more independent your pricing, the clearer your self-employment.

Measure 6: QR-bill and professional invoicing

Use a professional invoicing software for the self-employed that generates QR-bills (Swiss: QR-Rechnung) to the Swiss standard. Clean invoices with your own VAT number (if you are VAT-liable) and your own letterhead strengthen your position. With Magic Heidi you create QR-bills from CHF 25.00/month — compared to bexio (CHF 52.00/month) you save over 50%. More in the Magic Heidi vs bexio comparison.

Measure 7: Entry in the commercial register

For sole proprietorships (Swiss: Einzelfirma) with revenue from CHF 100,000.00, entry in the commercial register is mandatory — also for the VAT number with the FTA. Check on zefix.ch whether you should register. A sole proprietorship entry signals entrepreneurship.

Calculating AHV contributions: what genuinely self-employed persons pay

Self-employed persons pay AHV/IV/EO typically between 5.371% and 10.0% of their net profit — depending on the level of income. Specifically:

The specific rates are published annually by the AHV.

Note on VAT (Swiss: MWST)

With revenue above CHF 100,000.00 per year you are VAT-liable. The standard rate is 8.1% (as of 2026), the reduced rate is 2.6% for certain goods (under Art. 26 MWSTV). The FTA conducts a separate review. You file VAT returns quarterly.

Note: Revenue below CHF 100,000.00 = no VAT obligation, but voluntary reporting is possible. More on the topic of part-time self-employment in the article on being self-employed part-time.

Checklist: am I truly self-employed?

Check these 11 points for yourself. The more you answer with "yes," the more secure your self-employment.

• I have at least 3 active clients.
• No single client generates more than 50% of my revenue.
• I have my own AHV number and am registered with the compensation fund as self-employed.
• I have my own business equipment (laptop, software, tools).
• I have my own letterhead, own business cards, and my own business email address.
• I deliver my services at my own location (home office, co-working, own premises).
• I submit quotes and negotiate prices independently.
• I work with work contracts (Werkvertrag), not with employment-contract instructions.
• I invoice independently with my own QR-bill and VAT number (if relevant).
• I have a sole proprietorship (Swiss: Einzelfirma) or am registered in the commercial register (check zefix.ch).
• I have an AHV certificate from the compensation fund confirming my self-employment.

If you meet 8 or more points: your risk of bogus self-employment in Switzerland is very low. With 5 or fewer points, you should act urgently.

Key takeaways

• CHF 12,400.00 in retroactive payments loom after reclassification following 3 years — Thomas experienced it.
• CHF 19,500.00 additional costs per year for the employer who must classify a freelancer as an employee.
• At least 3 clients and a maximum 50% revenue share per client drastically reduce your risk.
• An AHV certificate costs nothing and is your best protection — as Sarah proved.
• CHF 25.00/month for Magic Heidi instead of CHF 52.00/month for bexio: professional invoicing, without expensive tools.

Conclusion: bogus self-employment in Switzerland is avoidable

Bogus self-employment in Switzerland is a serious matter — but it is avoidable. Anyone who acquires multiple clients, uses their own infrastructure, concludes clean work contracts, and presents an AHV certificate is on the safe side. Anyone who works with only one main client and accepts instructions is living dangerously.

The effort to prove genuine self-employment is manageable: an AHV certificate, a clean contract, a professional invoicing software for the self-employed, and several clients suffice. With Magic Heidi you invoice from CHF 25.00 per month, including QR-bills and quotes — significantly cheaper than bexio (CHF 52.00/month), and still professional. See the Magic Heidi vs bexio comparison.

Review your situation with the checklist above. Act before the AHV knocks. Because retroactive payments are expensive, reputational damage is even more so.
