Excise Duty or Excise Tax is a type of tax charged on goods produced within the country. It is a tax levied on the production or sale of a good.

Not to be confused with Customs Duty which is tax paid when importing a certain good, Excise Duty is paid when producing a good. So for example, if you want to brew your own beer for sale, then you would have to pay Excise Duty.
