He has a public-law employment contract for an 80% workload. His annual salary is CHF 280,000, and social security contributions are paid by the employer.
In addition, he holds a consultation hour for private patients at the Hirslanden Clinic one day per week. The clinic handles all administrative work (appointment coordination, billing, etc.) for 15% of the fee. Additionally, he pays a flat-rate room rental fee of CHF 800 per day. This results in a net income of CHF 100,000.
For BVG purposes, his insured salary is CHF 354,275 (280,000 + 100,000 minus the 2024 coordination deduction of 25,725).
In 2024, Albert Steiner made a lump-sum contribution of CHF 150,000 to his 2nd pillar pension plan; he also paid CHF 7,056 into his 3a pillar in 2024.
Albert Steiner lives in Baden AG with his wife and their two minor children.
2.2 Questions
- How do you assess the employment relationship with KSA
- How do you assess the employment relationship with the Hirslanden Clinic
- Can the buy-in to the 2nd pillar and the contribution to the 3a pillar be claimed for tax purposes?
2.3 Additional Facts I
Same basic facts: In 2024, Albert Steiner again made a contribution of CHF 150,000 to the 2nd pillar and paid CHF 7,056 into the 3a pillar.
The Steiner family moved from Freiburg, Germany, in 2023. After moving to Switzerland, Albert Steiner took advantage of the option for voluntary insurance through the Berlin Medical Association’s pension fund and paid the minimum annual contribution of the equivalent of CHF 6,000.
2.4 Question
Do the contributions to the Berlin Medical Association, as well as the fact that the family moved from abroad in 2023, affect the determination of Albert Steiner’s taxable income?
2.5 Additional Facts II
Albert Steiner resigned from his positions at KSA and Hirslanden as of December 31, 2023, and started his own business as a consultant for hospitals.
The withdrawal capital from the pension fund amounted to CHF 2,500,000 as of December 31, 2023. Albert Steiner had his pension assets of CHF 2,500,000 from the 2nd pillar paid out.
The sole proprietorship is not registered in the Commercial Register, and there is no website.
In connection with the 2024 tax return, financial statements for the sole proprietorship were submitted. These included various expenses for home office rent, internet costs, communication costs, vehicle costs, training costs as a golf instructor, as well as meal expenses incurred during visits to the golf course.
These expenses are offset by consulting income of CHF 2,500 and a fee of CHF 2,000 for a presentation.
The result shows a loss of CHF 25,000. There is no balance sheet.
2.6 Question
Is Albert Steiner to be classified as self-employed?
2.7 Adjustment of facts regarding Supplement II
In connection with the financial statements of the sole proprietorship submitted with the 2024 tax return, expenses were reported for the rental of infrastructure in hospitals, cost-sharing contributions toward personnel costs at the hospitals in Aarau, Baden, and Solothurn, home office rent, internet costs, communication costs, vehicle costs, training costs as a golf instructor, meal expenses incurred during visits to golf courses, as well as depreciation for the newly purchased vehicle and IT equipment. These expenses are offset by revenue of CHF 120,000, consisting of various payments received for services rendered to hospitals and health insurance companies.
The result shows a loss of CHF 55,000.
2.8 Question
Is Albert Steiner to be classified as self-employed?
2.9 Factual Adjustment II to Supplement II
Albert Steiner is very pleased with the strong start to his self-employment. After just two months, he is already struggling to keep up with the heavy workload. In addition, the complex consulting mandates are exposing him to increasing liability risks that his liability insurance does not fully cover. Therefore, after only three months, he decided to give up his self-employment and convert his sole proprietorship into a corporation as of October 1, 2024. Following the conversion, he receives a monthly gross salary of CHF 20,000 from his company.
2.10 Question
Is it sufficient if the self-employment lasted only 3 months?
2.11 Factual Adjustment III to Supplement II
Albert Steiner founded Spitalberatung Steiner AG in January 2024. As of July 1, 2024, he resigned from his position as chief physician at KSA and became self-employed as a consultant. The withdrawal capital from the pension fund amounted to CHF 2,500,000 as of June 30, 2024. Albert Steiner had his pension assets of CHF 2,500,000 from the 2nd pillar paid out.
Albert Steiner subsequently provides consulting services to various Swiss hospitals, which are invoiced and collected by Spitalberatung Steiner AG.
According to the financial statements as of December 31, 2024, this results in a profit of CHF 110,000.
The details of the income statement show that Albert Steiner invoices exclusively to Spitalberatung Steiner AG, and the service revenue of CHF 180,000 is offset by expenses of CHF 70,000.
Spitalberatung Steiner AG, in turn, reports a net profit of CHF 150,000.
2.12 Questions
- How should Albert Steiner’s activities be classified?
- What are the tax and social security implications?
3.1 Facts
In 2025, an exit takes place: A private equity fund acquires Top Solution AG. At the company’s headquarters in Zug, a tax ruling was obtained that recognizes the formula value as valid and confirms that the capital gain is tax-exempt after a holding period of five years.
The cantons of Aargau and Vaud, however, reject the formula value as unsuitable and do not recognize the tax exemption of the excess profit.
3.2 Question
How does the compensation fund of the Canton of Zug assess this case with regard to social insurance?
3.3 Additional Facts
Hans Grossfuss was able to acquire a stake in Top Solution AG six years ago. Since he is notoriously short on cash despite a very good income, he was unable to pay for the acquisition of the shares in Top Solution AG at the very favorable formula value.
Top Solution AG therefore granted him an interest-free loan. In the meantime, he has been able to repay only 40% of this loan.
