How the DGT's position has evolved
Current position
The ownership of assets determines who must declare capital gains or losses, as the tax levies the income of the taxpayer themselves. In the case of losses, these correspond solely to the person who has obtained them and cannot be offset by other heirs. Under the community property regime (régimen de gananciales), ownership of common assets is attributed equally to each spouse, which implies that the contribution of a separate asset generates a transfer and a possible capital gain or loss for the contributor.
The DGT's position does not show a doctrinal evolution regarding a single concept, but rather addresses ownership from different angles: economic impact, community property regime, assets abroad, and successions. The rulings maintain the consistency that legal ownership and the nature of the income define the taxpayer. No change in criterion is observed, but rather the application of ownership principles in diverse scenarios.
