How the DGT's position has evolved
Current position
To apply the tax neutrality regime in mergers, the operation must be carried out within a commercial context and must not have tax fraud or evasion as its main objective. The absence of valid economic motives creates a presumption of fraud, but the Administration must prove, through a global and case-by-case examination, that such objective is the primary one. The existence of tax loss carryforwards does not invalidate the regime if the merger benefits the resulting activities and does not seek the exploitation of said losses as its preponderant purpose.
The DGT's position remains constant in requiring valid economic motives to avoid the application of Article 89.2 of the Law on Corporate Tax (LIS). The evolution shows an important nuance regarding the burden of proof, establishing that the lack of economic motives allows for a presumption of fraud, but requires a global analysis to confirm that this is the main objective. It is confirmed that the mere existence of tax loss carryforwards is not sufficient grounds to deny the regime.
