How the DGT's position has evolved

Settled doctrine High confidence 13 rulings · 2014–2026

Current position

To apply the tax neutrality regime in the contribution of a business line, it is an indispensable requirement to maintain accounting in accordance with the Commercial Code. In leasing activities, it is required that the activity be economic through the use of at least one employee with a full-time employment contract. The assets must have been assigned to the activity for a minimum period to be integrated into the contributed business line.

The DGT's position has remained constant regarding the requirement of an autonomous economic unit and valid economic motives. However, the doctrine has specified the requirements for leasing activities, requiring the presence of labor personnel to validate the economic nature of the activity. The mandatory nature of commercial accounting has been reinforced, explicitly excluding the use of the simplified direct estimation method.

Turning points

  1. V0707-21

    Introduces the need to have at least one employee with a full-time employment contract to consider a leasing activity as economic.

  2. V2435-22

    Clarifies that the use of the simplified direct estimation method without commercial accounting prevents access to the special regime.
