How the DGT's position has evolved

Settled doctrine High confidence 15 rulings · 2014–2026

Current position

Registration in an IAE (Economic Activities Tax) heading exclusively authorizes the exercise of the specific activity described in said heading. If materially different or complementary activities are carried out, such as parking services in a retail business, an additional registration in the corresponding heading is required. Compliance with IAE requirements does not exempt one from complying with the specific administrative regulations of each sector.

The DGT's position remains constant in its interpretation of the specificity of the headings. Through rulings, it is confirmed that registration in one activity does not authorize the exercise of other related or complementary activities. The doctrine applies a criterion of exclusivity for each IAE heading.

Turning points

  1. V2728-14

    Establishes that registration in the IAE does not legitimize the exercise of an activity if specific regulations require other administrative requirements.

  2. V2406-16

    Defines that the payment of the fee for an activity exclusively authorizes the exercise of that activity.
