Evading a duty of excise describes deliberately avoiding payment of excise duty on dutiable goods (such as alcohol, tobacco and hydrocarbon oils), for example by smuggling, diversion, misdescription, false documentation or non-payment.
Across England & Wales, Scotland and Northern Ireland, this
conduct is typically prosecuted as fraudulent evasion of duty contrary to the Customs and Excise Management
act 1979, s 170. The prosecution must prove dishonest conduct deliberately intended to evade the chargeable duty. Liability can arise through importing, exporting, dealing in, concealing, or possessing excise goods with that dishonest intent, including diversions from duty-suspension regimes (for example, warehouse or in-transit movements). HMRC investigates and prosecutes; sanctions may include imprisonment, confiscation, forfeiture of goods and vehicles, and assessment of unpaid duty alongside civil penalties.
In Ireland, equivalent offences arise under the Customs Acts and excise legislation and are enforced by the Revenue Commissioners. While terminology and charging provisions differ, the practical focus is similar: knowing or dishonest conduct aimed at defeating payment of excise duty, with criminal penalties, forfeiture and recovery of the duty due.
“Evading a duty of excise” is a descriptive term; the offences are defined by statute and informed by case law on dishonesty and intent.
