The Belgian Official Gazette of 30 December 2008 published a circular concerning the reintroduction of diesel for professional purposes. As from 1 January 2009, the rate of the special excise duty will be increased each time the official maximum price is reduced. However, the increase of the special excise duty is capped at half the reduction of the maximum price (excl. VAT).
Since 2004, part of the excise duty can be recovered. All information concerning excise duty as from 1 January 2017 can be found here.
Special rules apply to companies that sell diesel to third parties from their own system. A declaration must be completed in the event of an increase or decrease in excise duties. The procedure to be followed is the same as it was in the past.
