How the DGT's position has evolved
Current position
The classification of the activity depends on whether the commission agent acts on behalf of another or on their own behalf. If acting on behalf of another, they perform commercial mediation and their income constitutes professional activity earnings. If acting on their own behalf, it is considered a commercial activity involving two transfers of goods subject to IVA (Value Added Tax): from the supplier to the commission agent and from the latter to the final customer.
The DGT's position remains constant by distinguishing the nature of the activity according to the mode of action. Rulings confirm that mediation without assumption of risk is professional, whereas acting on one's own behalf shifts the activity into the commercial and distribution sphere.
