How the DGT's position has evolved
Current position
Merger operations carried out in the commercial sphere under Royal Decree-Law 5/2023 and Article 76.1.c) of the LIS (Corporate Income Tax Law) may qualify for the tax neutrality regime. The existence of tax loss carryforwards in the absorbed entity does not invalidate the regime, provided that the operation strengthens the business activity and is not its predominant purpose. The application of the anti-abuse clause requires a global analysis to verify that the main objective is not fraud.
The DGT's position has remained constant since 2014, confirming that the existence of tax loss carryforwards does not prevent the special regime if valid economic reasons exist. The doctrine has maintained the requirement that the operation be carried out in the commercial sphere and that the predominant purpose is not tax evasion. The evolution is minimal, being limited to the update of the reference regulations (from Law 3/2009 to Royal Decree-Law 5/2023).
