How the DGT's position has evolved

Stable position Medium confidence 56 rulings · 2014–2026

Current position

The classification in the IAE (Tax Administration Index) depends on the real nature of the activity and not on the means employed. In teaching services, the distinction between professional activity (heading 826) or business activity (headings 933.9 or 934) lies in whether the provision is direct and personal or through an organization. In artisanal activities such as embroidery, the classification is determined by the technique (manual or otherwise) and the type of IVA (Value Added Tax) will depend on whether the product qualifies as an object of art.

The DGT's position remains constant in the application of the principle of primacy of substance over form. Throughout the rulings, a systematic application of the nature of the activity is observed to determine both the IAE heading and the applicable IVA regime and objective estimation method.
