Key legal question
Whether the appeal met the Federal Supreme Court's reasoning requirements under Art. 42 BGG and could be examined on the merits.
Extracted holding
No. The appeal did not engage in a targeted way with the decisive reasoning of the cantonal court and therefore lacked sufficient reasoning.
Extracted reasoning
The appellant merely repeated general arguments about his duties as a pharmacist and did not refute the lower court's finding that he had not proven the factual basis for a home-office deduction.
