Kernrechtsfrage
Whether the appeal to the cantonal administrative court was filed within time
Extrahierter Entscheid
The appeal was not filed within the applicable 30-day time limit.
Extrahierte Begründung
The taxpayer attacked the merits (tax residence) rather than the non-entry reasoning. He did not show any error in the cantonal court's timeliness analysis or any valid reason for reinstatement, and the stay of deadlines did not apply to direct federal tax.
