How the DGT's position has evolved
Current position
The distribution of water and the execution of hydraulic infrastructure works for irrigation carried out by irrigation communities are subject to IVA (Value Added Tax). The cost of said works, when integrated into the consideration for the supply, is taxed at the reduced rate of 10%. As they are taxable operations, the input VAT incurred on the works generates a right to deduction.
The DGT's position has undergone a radical shift. For years, it was maintained that water management and exploitation operations were not subject to IVA according to art. 7.11º of Law 37/1992. However, the latest ruling establishes that these activities are indeed subject to tax, applying the reduced rate of 10% when integrated into the supply.
Turning points
-
The criterion changes from non-taxability to being subject to IVA, indicating that the execution of hydraulic infrastructure works for irrigation is taxed at the reduced rate of 10%.
