How the DGT's position has evolved
Current position
To benefit from the tax neutrality regime, the merger must be carried out within the commercial sphere and comply with the requirements of article 76 of the LIS (Corporate Income Tax Law). The operation must not have fraud, tax evasion, or tax advantage as its main objective. The existence of tax loss carryforwards does not prevent the application of the regime if the merger strengthens the economic activity and the entities are operational.
The DGT's position remains constant in requiring valid economic motives and compliance with commercial regulations. Throughout the rulings, it has been reaffirmed that the presence of tax loss carryforwards does not invalidate the regime as long as it is not the main purpose of the operation. The doctrine has consolidated around the verification of economic substance versus tax benefit.
