How the DGT's position has evolved
Current position
The taxable event for the fee is the private use or special exploitation of local public domain. The installation of elements such as fences that protrude into the airspace of the public domain constitutes this taxable event. The determination of the taxable surface area is the responsibility of the local administration according to its tax ordinance.
The DGT's position remains constant in defining the taxable event as the private use or special exploitation of the public domain. Over the years, the doctrine has clarified the scope of the concept, distinguishing between the fee and the canon, and delimiting specific situations such as the passage of power lines or the installation of telecommunications infrastructure and fences.
