How the DGT's position has evolved

Stable position High confidence 8 rulings · 2015–2021

Current position

Heading 504.8 of the IAE (Economic Activities Tax) rates allows for the execution of complete industrial installations, including heating and cooling, provided that the machinery is neither sold nor supplied. Fixed installations anchored to the ground may be considered buildings for the purposes of the IVA (VAT) Law. However, removable elements that can be disassembled without damage to the object are not considered buildings.

The DGT's position remains constant regarding the application of heading 504.8 for industrial assembly without the supply of machinery. The doctrine has clarified the nature of installations to determine whether they constitute buildings according to the IVA Law. A distinction is made between elements anchored to the ground and those that can be disassembled without damage.

Turning points

  2. V5180-16
