How the DGT's position has evolved
Current position
Natural persons carrying out economic activities must comply with their census obligations using forms 036 or 037, regardless of whether they are exempt from paying the IAE (Economic Activities Tax). Registration in the IAE requires the submission of form 840 when no exemption exists. The determination of the correct heading depends on the nature of the activity and whether the value resides in the service or in the manufactured product.
The DGT's position remains constant regarding the distinction between tax payment exemption and the obligation to comply with census formalities. Rulings confirm that the cessation of activity is the sole reason for deregistration and that correct classification within the IAE headings depends on the specific activity carried out.
