How the DGT's position has evolved
Current position
The excluding magnitudes of the objective estimation method are evaluated independently for each taxpayer. The computation shall be joint if the activities are identical or similar and there is common management sharing personal or material resources. In this case, the activities of the spouse, descendants, ascendants, and entities under the income attribution regime in which the taxpayer participates must be included.
The DGT's position remains constant in its doctrinal core. The evolution shows a progressive expansion of the spectrum of subjects subject to joint computation, moving from including only the spouse in the 2014 and 2015 rulings, to integrating descendants, ascendants, and entities under the income attribution regime in the rulings from 2020 onwards.
Turning points
-
Expands the scope of application of the joint computation to include not only the spouse, but also descendants, ascendants, and entities under the income attribution regime.
-
Clarifies that the joint computation must be carried out between the taxpayer and the entity if the requirements of identity of activity and common management are met.
