The Taoiseach has all but confirmed that the highest rate of USC will be cut again in the next Budget.
Enda Kenny says the measure would cost the state €around €250 million - which he says would leave plenty of funds available for other measures.
At the launch of a Fine Gael election advert today he's again confirmed the government's plan to phase out USC entirely.
A cut of 1% to the top rate, of 5.5% - which applies to all income over €18,668 - would mean a saving of around €171 for an average worker, with savings rising as income climbs.
The finance minister Michael Noonan has separately added that he believes the abolition of USC is essentially a policy to create more jobs.
However the move has an outside chance of causing friction with Labour - who want to keep USC, or some kind of income levy, to apply to the highest earners.
