How the DGT's position has evolved
Current position
In the transfer of real estate, the tax base is the cadastral reference value as of the accrual date. If the declared value or the agreed price exceeds said value, the higher of the two amounts shall apply. In the absence of a reference value, the highest amount among the declared value, the agreed price, or the market value shall be used.
The DGT maintains a consistent position regarding the location of services related to real estate in the territory where they are situated, provided there is a direct relationship. Throughout various rulings, the nature of certain assets (such as solar parks or circuits) has been specified, and the tax base for transfers has been defined. No change in doctrine is observed, but rather an application of criteria to different factual scenarios.
