How the DGT's position has evolved
Current position
Market value is used as a comparison parameter to determine the existence of capital gains or losses in various transactions. In the absence of a cadastral reference value, the tax base shall be the highest among the declared value, the agreed price, or the market value. In cases of theft, the market value at the time of the theft serves to calculate the capital loss after reducing the acquisition price by depreciation.
The DGT does not present a doctrinal evolution regarding a single concept, but rather applies the concept of market value in a fragmented manner across different scenarios. The rulings analyze its use to determine the tax base in the absence of reference values, to calculate losses due to theft, or to value holdings in profit distribution processes.
