How the DGT's position has evolved
Current position
Proportional total spin-off operations may qualify for the tax neutrality regime if they are carried out within a commercial framework and the allocation of values is proportional to the partners' participation. It is not necessary for the assets to constitute business lines to apply this regime. The operation must respond to valid economic motives and must not have the primary objective of tax fraud or evasion.
The DGT's position remains stable regarding the requirement of valid economic motives to avoid prohibition due to tax purposes. An evolution is observed from the focus on share contributions and the need to maintain a 5% participation, towards the application of neutrality in proportional total spin-off operations. In the latter, it is confirmed that it is not mandatory for the assets to constitute business lines.
Turning points
