Questione giuridica chiave
Whether the complainant's tax domicile for 2005 was in Basel-Stadt or Zug under Art. 127(3) BV
Decisione estratta
The complainant's main tax domicile was in Basel-Stadt for the 2005 tax period.
Motivazione estratta
Weekly residence and employment in Basel created a natural presumption of tax domicile there. The complainant did not rebut it with sufficiently close personal and social ties to Zug; weekend stays with an uncle and a paper-only company were insufficient.
