Kernrechtsfrage
Whether the taxpayer could deduct lodging costs for weekly stays based on an imputed market rent for a room rather than actual expenses paid.
Extrahierter Entscheid
Only actually incurred accommodation expenses are deductible; the lower court properly limited the deduction to a share of the real rent paid.
Extrahierte Begründung
The concept of necessary work-related expenses does not allow recognition of hypothetical 'should-costs' instead of actual costs. A market-rate room estimate would be inappropriate where the taxpayer in fact paid only a preferential rent, because deductible earnings-related expenses must generally be actually borne, apart from flat-rate allowances.
