Kernrechtsfrage
Whether costs for infertility investigations and in-vitro fertilization qualify as deductible illness expenses
Extrahierter Entscheid
Only medical investigations to determine the cause of childlessness may qualify as illness expenses; IVF itself does not count as medical treatment preserving or restoring health, and the taxpayers also failed to prove deductible illness costs above the threshold.
Extrahierte Begründung
Illness expenses cover medical treatment aimed at preserving or restoring physical or mental health. Childlessness is not itself a disease, though it may result from one. The burden of proof for the deduction rests on the taxpayer, and the filed invoices did not show deductible illness costs or that the statutory threshold was exceeded.
