Question juridique clé
Whether the prerequisites for retrospective taxation for 2008 were met, in particular whether there were new facts or evidence unknown to the tax authority.
Solution extraite
No. The authority already knew at the ordinary assessment stage that the taxpayer had reported no income, had received no mandates, and had shown no business expenses; a later reassessment of the same facts is not enough.
Motifs extraits
Retrospective taxation under Art. 151(1) DBG and § 170(1) StG requires facts or evidence that were actually unknown to the authority at the time of the ordinary assessment. Here, the decisive circumstances were already in the file or were obtained through the authority's own inquiries before the assessment became final, so there was no genuinely new basis for reopening.
