Tánaiste Eamon Gilmore has said he he wants to cut taxes for middle-income families once the economic recovery takes hold.
Mr Gilmore said he believeds that those who were hit hardest during the recession should be the first to feel the benefits.
It's the first time a senior cabinet minister has openly discussed the idea of reversing the tax hikes imposed since the economic crisis began.
The Tánaiste said it is only fair to ease the burden on those who have felt it most.
"Simply what I'm saying is that we are in a situation now where we can, for the first time since the recession began, look to an improvement in the fortunes of the country," he said.
"And I think it's reasonable that in the course of time, (that) the families (and) households of this country who have borne the burden would get some share in the gain."
