Key legal question
Whether the taxpayer qualified for tariff A as a single parent living alone with children.
Extracted holding
Tariff A did not apply because the taxpayer did not live 'alone' with the child within the meaning of § 44 StG.
Extracted reasoning
The court adopted a functional economic approach: shared housing with another adult and her children, common kitchen and partly common facilities, and reduced living costs created a household community. The existence of a lease did not change this assessment.
