How the DGT's position has evolved
Current position
The tax base in transfers via auction is the Cadastre reference value, unless the acquisition value or the agreed price is higher. In judicial auctions, the transfer is understood to have occurred upon the issuance of the certificate by the Court Clerk. Regarding IVA (Value Added Tax), the transaction is subject to tax if the property is used for business activity, except for specific exemptions in building deliveries. The loss of the auction deposit is considered a capital loss for IRPF (Personal Income Tax) purposes.
The DGT's position has undergone a significant shift regarding the determination of the tax base. Initially, encumbrances were excluded from the hammer price, but they were subsequently integrated as part of the actual consideration. Finally, the criterion has shifted towards the application of the Cadastre reference value as the preferred magnitude.
Turning points
-
Modifies the previous criterion by establishing that the acquisition value includes the auction price plus the amount of the encumbrances assumed by the acquirer.
-
Establishes that the tax base shall be the Cadastre reference value, unless the acquisition value or the agreed price is higher.
