How the DGT's position has evolved
Current position
The 95% reduction in Inheritance and Gift Tax (ISD) for Historical Heritage assets requires the acquirer to be the spouse, descendant, or adoptee of the deceased. Ownership must be maintained for ten years following the death, and the asset's classification and registration must be proven according to regional regulations. Regarding Property Tax (IBI), the exemption for monuments or historical gardens is lost if the property is used for economic activities, even through partial leasing.
The DGT's position remains stable in its specific criteria. Regarding IBI, it has been reaffirmed that use for an economic activity, such as leasing, voids the exemption for the entire property without the possibility of pro-rating. In Inheritance Tax (ISD), the criteria regarding the historical heritage reduction remain constant concerning the obligation to maintain the asset and prove its registration.
Turning points
-
Clarifies that the leasing of real estate constitutes an economic activity, causing the loss of the IBI exemption on the entire property.
-
Establishes that use for an economic activity is an objective requirement and prohibits the pro-rating of the IBI exemption if only part of the property is used for economic activity.
