Andorra has increased its temporary diesel-price support for September 2026 through an additional refund of the special tax on hydrocarbons.

From 1 September to 30 September 2026, the total reduction for road diesel is EUR 0.15 per litre. The measure combines an additional EUR 0.10 reduction with the EUR 0.05 support already scheduled for September. [alto.ad], [byteseu.com]

The additional reduction is implemented through a partial refund of the special hydrocarbon tax. Importers and distributors benefit from the tax refund only where the reduction is passed on to consumers. [alto.ad], [byteseu.com]

The reporting on the implementing framework states that fuel operators must provide information on the quantities sold, prices applied and evidence that the tax reduction reached final consumers. The Department of Taxes and Borders may request additional information when verifying compliance. [alto.ad], [laveulliure.ad]

The additional EUR 0.10 measure applies to diesel. Unleaded petrol continues to receive the previously established EUR 0.05-per-litre reduction during September but does not benefit from the extra diesel support. [byteseu.com]

For operators, the measure requires accurate separation between fuel categories and sales periods. Records should demonstrate the litres sold during the eligible period, the reduction incorporated into retail prices and the connection between the amount refunded and the benefit provided to consumers.

The temporary arrangement ends on 30 September 2026 according to the available public reports. [alto.ad], [byteseu.com]
