Key legal question
Whether the taxpayer had her primary tax domicile in Ticino or in Canton X for tax year 2010.
Extracted holding
The taxpayer’s center of interests remained in Ticino; the alleged domicile in Canton X was not proven.
Extracted reasoning
The court relied on clear indicators linking her to Ticino: family residence, upbringing and schooling, business and sports organization ties, ongoing education and sports affiliation. In Canton X she had only a sublet room and no comparable social, professional, or material ties.
