How the DGT's position has evolved

Settled doctrine High confidence 11 rulings · 2014–2018

Current position

To qualify for the special spin-off regime, the segregated assets must constitute a line of business understood as an economic unit or an autonomous operation capable of functioning by its own means. This concept does not require strict compliance with the economic activity requirements of Article 5 of the LIS (Corporate Income Tax Law), especially regarding the leasing of real estate. The existence of a differentiated business organization with material and human resources is decisive.

The DGT's position remains constant throughout the sequence. The criterion establishes that the line of business does not require the economic activity requirements of the IRPF (Personal Income Tax) or the LIS, but rather the capacity to function as an autonomous operation with its own organization. The doctrine has remained stable since 2014.
