Kernrechtsfrage
Whether Zurich could assert tax jurisdiction over the company from 2002 based on actual management in Zurich.
Extrahierter Entscheid
Yes. The company's effective administration and management were in Zurich, while its Zug seat was only a letterbox domicile.
Extrahierte Begründung
For legal entities, tax residence follows the seat unless another canton is the place of actual administration. On the undisputed facts, Zurich was the place where the leading business activity was carried out.
