Questione giuridica chiave
Whether maintenance payments to an adult child are deductible for federal and cantonal income tax.
Decisione estratta
No. Contributions paid to a child who is no longer under parental authority are not deductible.
Motivazione estratta
Art. 33(1)(c) LIFD and the corresponding cantonal rule allow deductions only for maintenance paid to a parent for children under that parent’s parental authority; adult-child support falls outside that rule.
