The Social Protection Minister Joan Burton has called for the establishment of a charities regulator in the wake of the health agency funding debacle.
Ms Burton said the top-up of salaries by the Central Remedial Clinic and other charities shows the need for greater scrutiny.
Last week, the CRC admitted that money raised as part of charitable donations was given to executives to top-up their salaries, taking them over and above the Department of Health's pay scales.
However, she has again stopped short of calling for the resignation of the board of the CRC.
The Finance Minister Michael Noonan earlier said the top-ups controversy is "unacceptable".
Minister Noonan said the pay rules must be adhered to.
He also said how the Government reacts to the controversy is now a matter for the Department of Health, saying: "It's unacceptable really, that's why we are saying the pay guidelines have to be adhered to.
"We're in December now, so what that means is that from next year they'll have to obey the Government pay caps.
"The executive function in that respect is the Department of Health in the first instance through the HSE."
