Questione giuridica chiave
Whether profits from the limited partnership are income from self-employed activity subject to AHV contributions or exempt capital returns.
Decisione estratta
The profits are self-employment income subject to AHV contributions.
Motivazione estratta
Under Art. 20(3) AHVV, partners in a profit-oriented partnership are subject to contribution duty on their share of partnership income. The partnership's structure, contracts, and economic function showed an enterprise-oriented person association; the passive investment argument and tax treatment did not displace that presumption.
