How the DGT's position has evolved
Current position
The completion of a building is generally evidenced by the final construction certificate, which allows the operation to be classified as a first delivery subject to IVA (Value Added Tax). However, the existence of said certificate is not sufficient if the building is not objectively fit for use, as occurs when essential urban services such as potable water are lacking. In such cases, the construction is considered in progress and the delivery is subject to the general rate of 21%.
The DGT's position remains constant regarding the importance of the final construction certificate in determining the completion of a building. Nevertheless, the doctrine has evolved towards a more restrictive interpretation of completion, now requiring that the building be objectively fit for use. This implies that the construction certificate may be insufficient if basic urban services are not available.
Turning points
-
Establishes that the lack of essential urban services, such as potable water, qualifies the building as unfinished even if a final construction certificate exists.
