How the DGT's position has evolved

Settled doctrine High confidence 51 rulings · 2014–2022

Current position

To apply the special merger regime, the operation must be carried out within the commercial sphere according to Law 3/2009 and comply with article 76.1 of the LIS (Corporate Income Tax Law). The operation must respond to valid economic motives, such as the restructuring or rationalization of activities, and must not have the primary objective of tax fraud or evasion. Motives such as the saving of maintenance costs may be considered valid, although their assessment depends on the facts.

The position of the DGT has remained constant over time. Throughout the rulings, the need to comply with Law 3/2009 and the LIS has been reiterated, always requiring valid economic motives that do not merely seek a tax advantage. The evolution is limited to the mention of different examples of rationalization, ranging from the unification of management to the saving of maintenance costs.
