How the DGT's position has evolved
Current position
Renovation and repair works in buildings intended for residential use may be taxed at 10% if the recipient is an individual or a community of owners, the building is more than two years old, and the cost of materials does not exceed 40% of the taxable base. If the cost of materials exceeds this limit, the general rate of 21% applies. For rehabilitation works, it is required that the main purpose be reconstruction and that the cost exceeds 25% of the value of the building excluding the land.
The DGT's position remains stable regarding the application of the reduced rate of 10% for renovations and repairs, maintaining the 40% limit for the cost of materials. It has been specified that the suitability for residential use does not depend on the certificate of habitability or the occupancy license, but rather on the objective characteristics of the property. The doctrine confirms the application of the reduced rate also for photovoltaic installations and works in garages under the same conditions.
Turning points
-
Clarifies that the application of the reduced rate is not conditional upon the existence of a certificate of habitability or an occupancy license, based instead on the objective characteristics of the design.
