How the DGT's position has evolved
Current position
The reduced rate of 10% applies to the execution of works for the construction or rehabilitation of buildings intended primarily for housing, understanding this to mean that at least 50% of the surface area is for living or dwelling purposes. This rate does not extend to professional architecture services, nor to the construction of swimming pools or sports facilities. In the transfer of garages, the 10% rate applies if they are transferred together with the housing in the same act.
The DGT maintains the criterion that the 10% rate requires more than 50% of the surface area to be for housing use. Throughout the rulings, important exclusions have been specified, such as architecture services (V2322-21) and sports facilities or swimming pools (V0683-26). The doctrine has focused on delimiting which services and elements do not qualify as the execution of works for housing.
Turning points
-
Clarifies that fees for architects and technicians are taxed at 21% as they are not considered the execution of works.
-
Establishes that the construction of swimming pools or sports facilities is taxed at the general rate of 21%, excluding them from the reduced rate.
