How the DGT's position has evolved

Settled doctrine High confidence 77 rulings · 2015–2026

Current position

The contribution of a branch of activity requires that the transferred assets constitute an autonomous economic unit capable of functioning by its own means. This requires a differentiated business organization within the transferring entity that allows for the identification of an asset set destined for an economic exploitation. Furthermore, it is mandatory that the elements are assigned to an activity with commercial accounting, which must have been kept in accordance with the Commercial Code, at least since the fiscal year preceding the contribution.

The DGT's position remains constant in requiring that the branch of activity be an autonomous economic unit with its own capacity to function. The doctrine has progressively specified the technical requirements, emphasizing the need for a differentiated business organization and establishing a minimum period of commercial accounting to validate the operation.

Turning points

  1. V0656-26

    Clarifies that the mere division of isolated real estate properties does not constitute an autonomous economic unit as it does not allow for the identification of a differentiated business organization.

  2. V5004-26

    Establishes a temporal requirement for accounting, noting that it must have been kept in accordance with the Commercial Code, at least since the fiscal year preceding the contribution.
