Ethanol is taxed with a special tax controlled by the Ministerio de Hacienda, Dirección General de Impuestos, Sección de Impuestos Especiales.

The Law Impuestos Especiales 38/1992 of December 28, published in BOE 312 of December 29, 1992, and subsequent Reales Decretos and Órdenes Ministeriales indicates that the products subject to it are: undenatured ethanol, partially denatured and completely denatured.

The value of the Special Tax is published in the Ley de Presupuestos del Estado. The Law Impuestos Especiales indicates that these must be charged in invoice, separately from the price of the whole.

Some users may request exemption from the tax payment. The corresponding request must be made at the Inspección Regional de Aduanas e Impuestos Especiales of your province. In the event that the exemption is granted, you will be given a card indicating the type of alcohol authorized and the number of liters. The sale of ethanol exempt from payment of the tax, whether denatured or not, can only be made to the holders of the supply card, which entitles them to receive it.

To be able to meet your orders, we must receive, previously, a certified photocopy of the aforementioned card.

Ethanol shipments exempt from taxes generate an Documentos Electrónico de Acompañamiento DAC (Electronic Document of Accompaniment), which must be confirmed electronically by the recipient in a period not exceeding 5 days.
