Key legal question
Whether the taxpayer could deduct the full general-contractor fee as value-increasing construction costs.
Extracted holding
No. The fee was not deductible because the taxpayer failed to document the concrete work performed and the related expense in sufficient detail.
Extracted reasoning
General-contractor fees of a company controlled by the taxpayer may in principle be deductible, but they are treated like own services and require proof of the actual work and cost allocation. That proof was missing.
