Taoiseach Micheál Martin has told Fianna Fáil TDs that the State pension age should not go beyond 66 years old.
Mr Martin also told his parliamentary party colleagues at a meeting today that PRSI increases may be needed over time to fund this approach.
The Pension Commission report published last October said that the State pension age should rise by three months each year from 2028 until it hits 67 in 2031.
