Kernrechtsfrage
Whether the complainant's tax domicile for 2005 was in Basel-Stadt or Zug under Art. 127(3) BV
Extrahierter Entscheid
The complainant's main tax domicile was in Basel-Stadt for the 2005 tax period.
Extrahierte Begründung
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.
