How the DGT's position has evolved
Current position
The taxable base for ITPAJD (Transfer Tax and Stamp Duty) is determined by the reference value of the Cadastre, applying the higher of this and the declared value or the agreed price. In the absence of a reference value, the highest amount among the declared value, the agreed price, or the market value shall be used. For the calculation of capital gains or losses in IRPF (Personal Income Tax), the acquisition value must include the actual purchase amount plus expenses and taxes, incorporating the value verified by the Administration if it is higher.
The DGT's position does not show a single doctrinal evolution, but rather addresses heterogeneous scenarios ranging from exemptions in corporate restructurings to the determination of the taxable base. The most recent rulings focus on the application of the Cadastre reference value and its impact on determining the real value for IRPF. There is no change in criterion, but rather a specialization in the application of valuation parameters.
Turning points
-
Establishes that the taxable base shall be the reference value of the Cadastre, prevailing over the declared value or agreed price if the latter is lower.
-
Links the value verified by the Autonomous Community in ITPAJD with the actual amount to determine capital gains or losses in IRPF.
