Questão jurídica principal
Whether a taxpayer in a concubinage relationship may deduct payments made to the cohabiting partner for the maintenance of their child.
Decisão extraída
Yes. The taxpayer must be treated like a Swiss cohabiting partner and may deduct the maintenance payments made to the concubine.
Fundamentação extraída
The decisive consideration is equal treatment: a foreign taxpayer in the same family situation as a Swiss concubine cannot be treated less favorably for tax purposes regarding deductions for child maintenance payments.
