Questione giuridica chiave
Whether the gain from the sale of the property B. strasse in 2001 constitutes AHV-insurable income from self-employment
Decisione estratta
No. The sale gain could not be requalified as self-employment income because the property had previously been treated, for AHV purposes, as private assets and no material change in circumstances justified a new qualification.
Motivazione estratta
AHV qualification is not bound by tax classification as such, but a prior AHV assessment of the same asset as private cannot be changed for a later period without concrete new facts. The tax ruling treated the property as business assets only because no change had occurred since the earlier tax period; that does not overcome the prior AHV finding. The office had also never contribution-taxed the property's income, and there were no indications that the elderly widow had newly begun real-estate trading.
