How the DGT's position has evolved
Current position
A total demerger may qualify for the tax neutrality regime if carried out in accordance with Royal Decree-Law 5/2023 and complies with article 76.2.1.a) of the LIS (Corporate Income Tax Law). It is not necessary for the assets to constitute business lines, provided that the shareholders' participation in the new companies is identical to that of the demerged company. The regime will not apply if the main objective of the operation is tax fraud or evasion.
The DGT's position remains constant at the core of the criterion, confirming that proportionality in the transfer of shares waives the need to constitute business lines. The evolution shows a regulatory adaptation towards Royal Decree-Law 5/2023 and a constant reiteration regarding the prohibition of applying neutrality if tax fraud or evasion exists.
