How the DGT's position has evolved
Current position
The classification of the transaction depends on the relevance of the elements provided or the nature of the object. If the materials are means for a main contract, it is a provision of services; if the client provides a significant active ingredient, it is also a service. Prefabricated houses are buildings only if they are permanently attached to the ground; otherwise, they are taxed at 21%. The supply of prepared food is a delivery of goods if the accompanying services are irrelevant.
The DGT's position does not show a single doctrinal evolution, but rather applies technical distinction criteria according to the specific case. The differentiation between the delivery of goods and the provision of services based on the relevance of the elements or the permanence of the installation is maintained. The doctrine is applied in a fragmented manner depending on the nature of the good or service analyzed.
Turning points
-
Establishes the distinction between catering (service) and the supply of food (delivery of goods) according to the relevance of the accompanying services.
-
Defines that prefabricated houses are buildings only if they are permanently attached to the ground, applying 21% if they can be moved without damage to the object.
