How the DGT's position has evolved
Current position
Water management and exploitation operations carried out by irrigation communities are not subject to IVA (Value Added Tax) pursuant to Article 7.11 of Law 37/1992. However, the contracting of third parties to carry out infrastructure improvement works is not considered an activity of its own management, therefore the construction company must charge the tax. The production of electricity with market intent is a business activity subject to IVA.
The DGT's position remains constant regarding the non-subjectivity of activities inherent to water management and exploitation. The evolution shows a delimitation of the boundaries of this non-subjectivity, clarifying that the contracting of improvement works by third parties does not constitute an activity of its own management. It has also specified the subjectivity of electricity production when there is market intent.
