How the DGT's position has evolved
Current position
The classification of income depends on the existence of a fixed base or permanent establishment and the nature of the activity. In the field of intellectual property, the exemption for professional services requires the creation of original works with personal contribution. The distinction between income from employment and economic activities is based on whether the taxpayer organizes their own means of production and human resources.
The DGT maintains a consistent line regarding the distinction between professional services exempt due to originality and those subject to the general rate. A rigorous application of double taxation treaties is observed to determine taxing power through the existence of a fixed base. The doctrine has specified the limits of the exemption for teaching and the nature of artistic creations.
Turning points
-
Establishes that the exemption for teaching requires the activity to consist of the transmission of knowledge without a recreational character and to be included in recognized curricula.
-
Extends the exemption for professional services regarding copyrights to the creation of texts for guides, catalogs, or websites, provided they constitute an original work.
-
Clarifies that a report or study on a work does not constitute an original artistic creation, remaining subject to the general rate of 21%.
