How the DGT's position has evolved

Stable position High confidence 16 rulings · 2014–2024

Current position

The main economic activity encompasses the activities within the corporate purpose, those that comprise the production cycle, and those necessary for the organization of work. In the context of subsidiary liability, the contracting or subcontracting of works or services related to said activity generates liability for tax obligations involving pass-through or withholding. This liability is strictly limited to the portion corresponding to the services subject to the contract.

The DGT's position remains constant regarding the definition of the main economic activity, integrating both the corporate purpose and the activities necessary for organization. No doctrinal changes are observed, but rather a repeated application of the concept to determine subsidiary liability in subcontracting. The most recent rulings specify the scope of said liability in terms of amount.
