Key legal question
Whether the taxpayer was entitled to half child deductions under cantonal tax law despite claiming child support deductions for the same children.
Extracted holding
No. Child support deductions and child deductions cannot be cumulated; alternating custody does not change this.
Extracted reasoning
The court held that Art. 36(3) DStG must be interpreted in light of its purpose and history. A child deduction is only split where no child support payments are claimed; otherwise there would be a double tax relief. Alternating custody is not controlling for this purpose.
