Question juridique clé
Whether income from the properties qualified as income from self-employed activity subject to AHV contributions
Solution extraite
The properties remained business assets of a commercial real estate trading activity; the resulting income was contribution-subject self-employed income.
Motifs extraits
The decisive factor was the overall entrepreneurial activity after the end of the farming business: subdivision, sale, development, construction and operation of the properties. The later treatment as private assets was an obvious tax-office error and did not create reliance protection.
