REHAB chief Angela Kerins was revealed to have an annual salary of €240,000 as well as a 6pc payment towards her pension.
The charity boss is paid €54,650 more than the Taoiseach Enda Kenny.
As part of her pay package Ms Kerins has the use of a company car on which she pays Benefit in Kind tax, the board of Rehab has revealed.
However, in a statement the group identified that the chief executive has voluntarily waived a bonus for the last four years.
The board held a special meeting of the Rehab directors yesterday and decided to make public the fact that no contribution towards private health insurance for any member of staff is made.
While Ms Kerins' salary and pay package was disclosed after the meeting, the board said that the same would be done for other senior managers in next year's accounts.
The group receives more than €82m a year from the HSE |and other State agencies |and has a turnover of |approximately €200m from its overseas and Irish operations.
The board meeting arose after Ms Kerins came under pressure to disclose her payment package following calls from Taoiseach Enda Kenny and Health Minister James |Reilly.
In yesterday's statement, the board listed a number of reasons why it had been reluctant to publish the details of Ms Kerins’ salary.
“Firstly Rehab continuously competes for business at home and abroad with a range of private companies which do not have to disclose such information,” the board said in a statement.
“Secondly, we wanted to receive up-to-date advice from our legal and remuneration advisors, and thirdly, we are also acutely conscious of our duty to all of our employees under privacy law and the Data Protection Acts 1998 and 2003.”
Fundraising Ireland described Ms Kerins' salary as “out of touch with the realities in the overwhelming majority of not-for-profit organisations in Ireland”.
Anne Hanniffy, CEO of Fundraising Ireland, said the “speculation and mistrust that has surrounded this issue for years has certainly caused damage to the charity sector and to the people who are so reliant on their work and support”.
Rehab is to be asked to appear before the Public Accounts Committee in the future to discuss its State-contracted work.
