Key legal question
Whether Zurich monistic property gain tax requires set-off of business losses against property gains
Extracted holding
No. Art. 12(4) StHG does not oblige cantons to allow loss offset in the monistic system; Zurich may exclude it.
Extracted reasoning
Property gain tax is an object tax focused on the real estate gain. The StHG leaves cantons freedom on loss set-off, and federal law does not impose consideration of the taxpayer's overall economic situation.
