How the DGT's position has evolved
Current position
The supply of e-books, whether by download or streaming, is taxed at the reduced rate of 4% IVA (Value Added Tax). The assignment of an ISBN code is considered an indication to qualify a product as a book, although it is not decisive on its own. The reduced rate does not apply if the content consists entirely or predominantly of music, video, or if the product is learning material with its own application or program functionality.
The DGT's position has remained constant regarding the use of the ISBN as an indication for the application of the 4% reduced rate. Throughout the rulings, it has been specified that this indication is not decisive and that the nature of the content (predominance of video, music, or software functionality) prevails over the existence of the code.
Turning points
-
Establishes that the assignment of an ISBN code is an indication or presumption, but clarifies that it is not decisive on its own for the application of the reduced rate.
-
Specifies that if the product is virtual learning material with its own structure and functionality, it is considered a different product from a book, regardless of the ISBN.
