21% VAT on water supply contracting

The Dirección General de Tributos (DGT) has issued a relevant ruling regarding the application of Value Added Tax (IVA) on operations related to water supply, specifically concerning the initial contracting costs.

What the DGT has ruled

The query concerned the VAT rate applicable to the water supply contracting operation. Following an analysis of current regulations, it has been determined that the water supply contracting fee must be taxed at the general rate of 21%.

This criterion applies specifically to concepts derived from:

  • The service connection fee.
  • The technical enablement necessary for the supply.

The resolution is based on the application of Law 37/1992 and Law 58/2003, establishing that these services are not subject to reduced rates but must follow the general rule of the tax.

What this means for you

This pronouncement has a direct impact on two profiles:

  • Supplying companies: They are obliged to apply the 21% tax rate in their billing relating to the connection and technical enablement concepts for new users.
  • Water consumers: Both companies and individuals starting a supply contract must bear the cost of VAT at the general rate in the connection or service contracting fee.

What should be done

It is necessary for companies in the water supply sector to verify that their billing systems and tax models correctly reflect this tax rate to avoid potential contingencies with the Tax Administration. Since the application of the VAT rate depends on the technical nature of each invoiced concept, it is recommended to assess each particular situation to ensure compliance with current regulations.
