How the DGT's position has evolved
Current position
Construction works for the building, rehabilitation of buildings, or land development trigger the reverse charge mechanism for the taxable person. However, the drafting of technical projects, construction management, or project management do not have the legal nature of construction works. These professional activities are taxed at the general rate of 21% and are not subject to the reverse charge mechanism.
The DGT's position remains constant in the distinction between the physical execution of the work and intellectual or management activities. Rulings confirm that while earthmoving or the construction of autonomous substations are construction works, management services, drafting of projects, or technical management are not.
Turning points
