Excise Duties

Storage terminals are fiscal warehouses for the purposes of excise duties on hydrocarbons and alcohols, and their holders are the taxpayers of these taxes, obliged to collect them from their customers and enter them into the Public Treasury. This fact constitutes one of the main risks of the business of the member companies of ATliq, which annually enter the Public Treasury more than 10,000 million euros.

Consequently, the Association pays special attention to the modifications of the regulations related to these taxes, presenting allegations and proposals to the Bills so that they reflect the needs and conditions required by the operations of the associates or improve their efficiency, reduce risks and improve legal certainty.

A significant number of storage terminals are located in Ports or Airports, infrastructures that are considered Special Properties of Properties (BICEs), which implies that all the assets located within a BICE are valued with criteria that lead to an increase in the amount of the IBI.

ATliq has been carrying out negotiations with the General Directorate of Cadastre to adjust the valuation of the tanks and other elements of the terminal to more reasonable criteria and monitoring the procedures to correct discrepancies that are reducing the cost of IBI of the terminals that have taken this procedure.
