How the DGT's position has evolved
Current position
The first delivery of a building is subject to IVA (Value Added Tax), applying the 10% rate if the property is suitable for residential use according to its design and construction characteristics, without requiring a certificate of occupancy. The operation is considered a second delivery and is exempt if there has been uninterrupted use for more than two years by a third party or if the property was already built at the time of acquisition. The taxable person may waive the exemption if the acquirer has the right to deduction.
The DGT's position remains constant regarding the distinction between first and second delivery based on two years of uninterrupted use. An evolution is observed towards the simplification of requirements to determine residential suitability, dispensing with the certificate of occupancy. The criterion has consolidated around the nature of the building and the property's usage history.
Turning points

Establishes that suitability for residential use is determined by objective design and construction characteristics, without the certificate of occupancy being essential.
