Key legal question
Whether income from participation as Kommanditist in a German GmbH & Co. KG is AHV-relevant self-employment income.
Extracted holding
Yes. Under Art. 20(3) AHVV, the income of a participant in an for-profit partnership without legal personality counts as self-employment income, regardless of personal work contribution.
Extracted reasoning
The provision is lawful and applies whenever the entity is an acquisitive partnership without legal personality. Influence in management, size of the business, or the capital-like character of the participation are not decisive.
