How the DGT's position has evolved
Current position
The supply of electronic books is taxed at the reduced rate of 4%, regardless of whether it is carried out via download or streaming. To apply this rate, the content must not consist predominantly of advertising, video, or music. The assignment of an ISBN code is used as an indication to qualify a product as a book.
The DGT's position has evolved from a distinction between physical media and download (which applied the 21% rate) towards a total equalization of the digital book with the physical one at 4%. The doctrine has clarified that access via streaming or virtual libraries also allows for the use of the reduced rate, provided that the purpose is reading.
Turning points
-
Establishes that supply via download is taxed at 4% and extends this rate to ancillary services such as videos or forums if they are not the main product.
-
Extends the 4% rate to streaming and uses the assignment of an ISBN as an indication of a book.
