Revenue chairman Josephine Feehily has said that she will retire shortly after serving 41 years in the civil service.
The first woman to hold the post, Ms Feehily was appointed as chair of the Revenue Commissioners to succeed Frank Daly in March 2008.
Ms Feehily was a Revenue Commissioner for ten years before becoming its chairman. She also served in a number of other roles in Revenue over the years, including as account general.
A career public servant, Ms Feehily previously worked in a range of positions in the Department of Social Welfare and the Pensions Board. From Co Limerick, she is a graduate of the National College of Ireland and Trinity College Dublin.
The process to find her successor has started with an advertisement for a new commissioner on the Public Appointments Service website. The closing date for applications for the role is October 2.
