How the DGT's position has evolved
Current position
The determination of the IAE (Economic Activities Tax) headings depends on the nature of the activity, the business organization, and the scope of commercialization. In the case of livestock farming, the sale of products outside the municipal area of production requires registration in wholesale trade headings. For vehicle rental, the quantification of the fee includes all vehicles assigned to the activity, whether owned or through leasing or renting.
There is no doctrinal evolution regarding a single concept, as the rulings address heterogeneous criteria on different headings. The DGT's position remains constant in the application of specific rules for each sector, such as the distinction between professional and business activity or the delimitation of commercial activity according to the geographical scope.
