How the DGT's position has evolved
Current position
The tax base in real estate transfers is the reference value of the Cadastre, unless the price, consideration, or declared value is higher. In the absence or impossibility of certifying said reference value, the base shall be the highest among the declared value, the agreed price, or the market value. The nature of the land (rural or urban) for the application of the IIVTNU (Tax on Real Estate Value) is determined according to the regulatory rules of the Real Estate Cadastre.
The DGT's position has evolved from the application of criteria regarding the nature of the land in 2014 towards a technical consolidation on the use of the Cadastre's reference value following its implementation. The most recent rulings (2023-2026) unify the treatment of the tax base and the mechanisms for action in the event of a lack of reference value or the need for an appeal.
Turning points
-
Establishes that the reference value is the default tax base, unless the price or declared value is higher, clarifying that repair needs do not modify this rule.
-
Introduces the procedure for action in the event of the non-existence or impossibility of certifying the reference value, setting the base as the highest among the declared value, the agreed price, or the market value.
