Kernrechtsfrage
Whether the complaint was admissible as administrative court appeal under Art. 73 StHG despite the cantonal transitional rules.
Extrahierter Entscheid
The appeal was admissible because the dispute concerned the implementation of binding federal harmonization law on the transition to annual taxation.
Extrahierte Begründung
Art. 69 StHG applied from 1999 for cantons that changed to the new assessment system. Zurich had no room to deviate from the federal concept of extraordinary income, so the matter fell under Art. 73 StHG.
