How the DGT's position has evolved
Current position
Public business entities have the status of entrepreneurs and their operations are, in principle, subject to IVA (Value Added Tax). However, services provided as an instrumental own-means of the Administration to which they belong shall not be subject to tax, provided that the latter holds full ownership. There are specific exceptions to taxation for energy, transport, telecommunications, and the integrated water cycle activities.
The DGT's position remains constant in the distinction between activity as an instrumental own-means and activity as an entrepreneur. Non-taxation has been maintained for services provided to the dependent Administration with full ownership, but exceptions to taxation have been specified for specific sectors such as water or transport.
Turning points
-
Specifies the IVA taxation of integrated water cycle activities, even when provided to the Public Administration to which the entity belongs.
