Excise duty is a tax imposed on goods produced domestically in Bangladesh. It is levied on the manufacture, sale, or purchase of commodities and services within Bangladesh but not on imported goods. Excise duty rates can be specific amounts based on quantity or ad valorem based on value. The duty is imposed to discourage consumption of undesirable goods or control consumption of scarce commodities. It is collected by the Customs, Excise and VAT wing of the national board of revenue on goods and services listed in the Excise and Salt Act of 1944 such as bidis, cloth, and banking services.
