How the DGT's position has evolved
Current position
Taxation on the variable quota of AJD (Stamp Duty) in new construction declarations is based on the real value of the material execution cost, without updating to market value. In cases of guarantees, the tax base includes the total amount covered by the condition or guarantee. The cancellation of resolutory conditions is only taxed if formalized through a notarial document, deed, or act.
The DGT's position remains constant regarding the determination of the tax base for different AJD scenarios. Technical precision is observed concerning the nature of the real cost value in new constructions and the distinction between notarial and private formalization for the cancellation of conditions.
Turning points
-
Clarifies that the real cost value of new construction is the material execution cost and not its market value, without the possibility of updating.
-
Establishes that the cancellation of a resolutory condition is only taxed if carried out through a notarial document, deed, or act, excluding private documents.
