Kernrechtsfrage
Whether the disputed property renovation expenses were deductible maintenance costs or non-deductible value-enhancing expenses.
Extrahierter Entscheid
The court held that the demolition and reconstruction of walls had a substantial value-enhancing component; the authority’s estimated split was not objectionable.
Extrahierte Begründung
For private property, only maintenance costs are deductible. Where work combines maintenance and value enhancement, only the maintenance portion may be deducted and the non-deductible part may be estimated. Here, the extensive restructuring and wall work justified the authority’s assessment.
