Kernrechtsfrage
Whether car commuting costs exceeding 18,000 km may still be deducted on a flat-rate basis under the tax ordinance.
Extrahierter Entscheid
No. Once the annual commuting/working driving total exceeds 18,000 km, only actual and proven costs are deductible; the flat-rate regime no longer applies.
Extrahierte Begründung
The court held that the purpose of the rule is to simplify taxation only within a reasonable threshold. The decisive factor is the total work-related kilometers, not whether they stem from commuting alone or also from business trips.
