How the DGT's position has evolved
Current position
The tax base of the tax group is determined by summing the individual tax bases of the constituent entities and applying the corresponding eliminations. For the exemption of income from the transfer of shares, compliance with the requirements regarding participation and holding must be assessed at the tax group level. If the holding is not uninterrupted at the group level in the year prior to the transfer, the positive income from the internal transaction shall not be exempt.
The DGT's position remains constant regarding the mechanics of determining the tax base through the summation of individual bases and the application of eliminations for internal transactions. The doctrine has specified that the assessment of requirements for exemptions, such as uninterrupted holding, must be carried out considering the perspective of the tax group and not just that of the individual entity.
