How the DGT's position has evolved
Current position
The administrative concession is not subject to IVA (Value Added Tax) according to article 7.9 of Law 37/1992. However, the services provided by the concessionaire to the Administration (maintenance, management, waste collection) are subject to the tax. Contributions from the Administration to finance public services are not considered consideration or subsidies linked to the price if there is no significant distortion of competition.
The position remains stable regarding the distinction between the non-subjectivity of the concession and the subjectivity of management services. The evolution focuses on precision regarding the nature of public contributions, clarifying that they do not form part of the tax base if the absence of competition distortion prevents them from being considered subsidies linked to the price.
Turning points
-
Establishes that contributions to finance services where there is no significant distortion of competition are neither consideration nor subsidies linked to the price.
-
Reiterates and confirms that in services such as interurban transport with fixed tariffs, the contribution does not generate competition distortion and does not form part of the tax base.
