Kernrechtsfrage
Where was the taxpayer's tax domicile on 31 December 2005?
Extrahierter Entscheid
The taxpayer's tax domicile was in Solothurn, not in Zug.
Extrahierte Begründung
For an unmarried person over 30 who lives in a rented apartment and works from that place, the presumption in favor of the workplace as center of life is strong. The asserted ties to the parental home in Zug, such as visits to hairdresser, doctor, optician, and laundry by the mother, did not outweigh the ties to Solothurn.
