How the DGT's position has evolved
Current position
To apply the tax neutrality regime, the operation must comply with article 76.1.c) of the Law on Corporate Income Tax (LIS) and the commercial scope. In this case, income is not recognized from the cancellation of the shareholding, and the values and seniority of the assets are maintained. The absorbed company's tax loss carryforwards may be offset in the absorbing company pursuant to article 84 of the LIS.
The DGT's position remains constant regarding the application of the special merger regime. It is confirmed that the existence of tax loss carryforwards or the sole participation of a shareholder does not prevent neutrality, provided that valid economic reasons exist. The doctrine has maintained technical coherence over the years.
