Kernrechtsfrage
Whether the claimed base fees for water, electricity, chimney sweeping, wastewater and waste collection are deductible as maintenance costs under direct federal tax law for a self-used property.
Extrahierter Entscheid
No. For an owner-occupied property, only maintenance costs directly linked to the taxable rental-value income are deductible; the disputed fees are ordinary living expenses and thus non-deductible.
Extrahierte Begründung
The court held that recurrent utility base fees are not sufficiently connected to the creation or preservation of an income source. A schematic allocation into fixed and variable components is rejected; such charges, even if invoiced separately, are to be treated uniformly and, insofar as they are not fully gain-related, as living expenses.
