The Census and Excise is an organization operated by the Empire in an attempt to manage census counting and for tax/excise purposes. Imperial taxes are based on head counts of citizens. Census and Excise is responsible for both head counts and tax assessment and collection. Census and Excise officers also administer many Imperial licenses, e.g. importation, mercenary company incorporation.
They are typically found in many major ports across Tamriel, such as Seyda Neen in Vvardenfell where they have an office.
