Questione giuridica chiave
Whether the GmbH and the sole proprietorship formed one taxable person for VAT purposes under economic unity principles.
Decisione estratta
Yes. Because the activities overlapped, there was no spatial separation or clear external distinction, and the businesses were personnel-linked, the civil-law form did not match the economic reality; the authority could treat them as one taxable person.
Motivazione estratta
VAT follows economic reality where the civil-law structure does not correspond to the actual business arrangement. The separate legal forms were unusual and not plausible in the circumstances.
