How the DGT's position has evolved
Current position
The reduced rate of 10% applies to works executed for the construction or rehabilitation of buildings intended for housing, based on objective design characteristics and not on the certificate of habitability. In renovation operations, if the supply of materials is less than 40% of the taxable base, they are considered provisions of services with accrual upon advance payments. Likewise, the 10% rate applies to deliveries of wood intended for fuel or biomass manufacturing according to current regulations.
The sequence does not show a doctrinal evolution regarding the concept of entrepreneur, but rather presents scattered criteria on various scenarios for the application of tax rates and accrual. The criteria regarding the status of the taxable person or the deductibility of expenses remain constant in their technical application without detectable changes in trend.
Turning points
-
Establishes that suitability for housing use does not mandatory require a certificate of habitability or an occupancy license, based on objective design characteristics.
