How the DGT's position has evolved
Current position
Gains from the disposal of shares in a Spanish company are taxed in Spain if there is a substantial participation or if the company's assets consist mainly of real estate. Substantial participation is considered to exist when the transferor, together with their direct relatives, holds at least 25% of the capital or profits in the previous twelve months. Otherwise, the taxing power belongs to the State of residence of the transferor.
The DGT's position does not show a single doctrinal evolution, but rather applies specific criteria according to the applicable Double Taxation Convention and the nature of the company. A constant application of the 25% substantial participation rule is observed to determine the taxing power in Spain against non-residents.
