How the DGT's position has evolved

Settled doctrine High confidence 42 rulings · 2016–2026

Current position

Operations within the integrated water cycle (abstraction, supply, purification, sewerage, and treatment) are subject to IVA (Value Added Tax). The reduced rate of 10% applies to the supply of water suitable for human consumption, animal use, or irrigation, as well as to sewerage cleaning services and wastewater treatment. Connection fees and the installation thereof are taxed at the general rate of 21%. Contributions to finance infrastructure do not constitute consideration and are not subject to the tax.

The DGT's position remains constant regarding the subject to IVA of activities within the integrated water cycle. The doctrine has specified the nature of contributions for infrastructure, clarifying that they do not constitute consideration, and has delimited that connection fees do not benefit from the reduced rate.
