Professional diesel in Portugal: rebate of about 10.74 cents from Monday
ANTRAM points to €0.1074/l from 14 September. The new excise duty rate has already been published.
From 14 September, ANTRAM puts the professional diesel rebate at around €0.1074/l, against €0.1085/l up to the 13th. The figure is the estimate published in the association’s update of 11/09.
Portaria No 430-A/2026/1 confirms that it takes effect on Monday and sets the excise duty on road diesel on the mainland at €264.02 per 1,000 litres. That tax figure is not the amount of the rebate.
For an eligible fill of 500 litres, ANTRAM’s rounded values work out at about €53.70, €0.55 less than the week before. It is an illustrative calculation; the rebate depends on qualifying under the scheme.
