How the DGT's position has evolved

Settled doctrine High confidence 21 rulings · 2014–2024

Current position

The reduced rate of 5% applies exclusively to the supplies of natural gas goods carried out in one's own name. The heating service, although it uses gas as an input, is subject to the general rate of 21%. The supply of domestic hot water is considered ancillary to the heating service and follows the same taxation. For the classification of regasification, the gas must be natural and distributed via pipeline connected to the National Gas Pipeline Network.

The DGT's position has moved from focusing on the identification of professional uses through the IAE (Economic Activities Index) to apply reduced rates, to strictly delimiting the nature of the operation. The most recent rulings clarify that the benefit of the 5% reduced rate is for the supply of goods and not for the heating service provided by energy management companies. The doctrine has consolidated in the distinction between the supply of goods and the provision of services.
