Questione giuridica chiave
Whether the Zurich domicile decision caused prohibited intercantonal double taxation for 1995-1996
Decisione estratta
Yes, because Solothurn had already validly taxed the self-employed income for 1995-1996, so Zurich could not also tax that same income for those years.
Motivazione estratta
The taxpayer had a business tax domicile in Solothurn for his self-employed activity from 1 January 1995. Zurich could only retain the main tax domicile for other income and assets; the self-employed income had to be allocated to Solothurn.
