Enda Kenny has expressed his disappointment that Coillte's CEO has not acceded to a 15% salary cut.
The Taoiseach's remarks about the company's boss David Gunning were made at the Fine Gael Presidential dinner in Dublin tonight.
Coillte is the only agency to refuse to take a cut. Its chief executive was paid a salary of €297,000 in 2010.
In a statement yesterday Coillte said: "No decision has been taken to date in respect of the voluntary waiver."
The forestry body is the only semi-State agency to resist the Government's request for a 15% pay cut at the top.
Minister for Public Expenditure & Reform Brendan Howlin asked the chief executives of commercial semi-States five months ago to take a 15% pay cut where their salary was above €250,000.
Mr Howlin set new pay levels for new appointees to the public service in June.
However, these could not be forced on those already in their jobs, according to legal advice from the Attorney General.
The minister then publicly asked semi-State chief executives to volunteer a 15% cut.
This applied if their pay was over €250,000 for commercial semi-States, with a threshold of €200,000 for non-commercial bodies.
Eight agencies came in above the pay ceiling. Of these, seven have agreed to take a 15% cut.
They are An Post, National Roads Authority, Bord Gáis, Irish Aviation Authority, ESB, Iarnród Eireann and Dublin Airport Authority.
Fianna Fáil Finance Spokesman Michael McGrath said it is entirely unacceptable that the CEO of Coillte is being paid €100,000 more than the Taoiseach given the very serious crisis the country is facing.
