How the DGT's position has evolved
Current position
The classification within the IAE (Business Activity Tax) Tariffs is determined exclusively by the true material nature of the activities performed. The corporate purpose or the formal name of the establishment do not condition the taxation. The taxpayer must register in all headings that correspond to the activities actually carried out.
The DGT's position has remained constant since 2014, reaffirming that economic reality prevails over legal form or denomination. Rulings have applied this principle of material nature to various sectors, from mixed commerce to the metallurgical or paper industries. No changes in criterion are observed, but rather a repeated application of the same principle to different scenarios.
