How the DGT's position has evolved

Settled doctrine High confidence 31 rulings · 2014–2026

Current position

The classification of activities is determined by their true economic nature. If the activity is not specified in the Tariffs, the rule of classification by analogy with the most similar heading is applied. If the service is performed within an organization, it is classified as a business activity in the first section and not as a professional activity in the second section.

The DGT's position remains constant in the use of analogy for unlisted activities. The evolution shows a systematic application of the material nature of the activity to avoid the generic use of n.e.c. (not elsewhere classified) headings. The distinction between business and professional activity has been clarified according to the organizational framework.

Turning points

  1. V1324-14

    Establishes that classification depends on the true nature of the activity, differentiating between real estate rental and lodging services.

  2. V5113-26

    Determines that if the activity is performed within an organization, it is a business activity (first section) and not a professional activity (second section).
