Revenue consists of a chairman and two commissioners, all of whom have the status of secretary general as used in Departments of State.

[7] Revenue is based in Dublin Castle and uses a symbol of its gates as its logo, while its staff work in almost all of the 26 counties of the Republic of Ireland.

The mission statement of Revenue is "to serve the community by fairly and efficiently collecting taxes and duties and implementing Customs controls".

A number of cases involving the Revenue Commissioners have received widespread media attention and/or involved material funds: In August 2016, Revenue became central to the proposed application of what would have been the largest recorded tax fine in history.

[16] The Revenue Commissioners operate two customs cutters for maritime patrols such as prevention of drug smuggling and illegal importation of other illicit goods into Ireland.
