Kernrechtsfrage
Whether the lower court had to assess supplementary wealth tax under § 50(3) StG/TG based on the change from yield-value to market-value taxation under § 44(2) StG/TG.
Extrahierter Entscheid
Yes. For parcels in a building zone falling under § 44(2) StG/TG, the supplementary wealth tax is determined by the time of the reclassification, while payment falls due only upon sale.
Extrahierte Begründung
The cantonal scheme mirrors Art. 14(2) StHG: the tax compensates the loss of the privileged yield-value assessment. § 50(3) StG/TG would be superfluous if taxation were fixed only at sale; it therefore requires determination at the moment the criteria for yield-value assessment cease to be met.
