How the DGT's position has evolved

Settled doctrine High confidence 64 rulings · 2016–2026

Current position

To apply tax neutrality in spin-offs or contributions, the transferred assets must constitute a line of business understood as an autonomous economic unit capable of functioning by its own means. This requires a differentiated business organization and separate management within the transferring entity. The existence of this autonomy is a question of fact that must be proven, and the mere segregation of isolated assets is not sufficient.

The DGT's position has shifted from focusing on the 5% participation requirements in non-monetary contributions (V0364-16, V2053-19) to delving deeper into the technical definition of a line of business for spin-offs. The most recent rulings (V1755-25, V0209-26, V1028-26) have tightened the interpretation, requiring a differentiated business organization and separate management to validate economic autonomy.

Turning points

  1. V1755-25

    Introduces the requirement that the segregated assets must be a line of business with a differentiated business organization and autonomous economic exploitation.

  2. V1028-26

    Establishes that the autonomy of the line of business is a question of fact that must be proven and that the activity must have previously existed in the transferring entity.
