The Taoiseach Enda Kenny is warning there will be no more money than already promised in next month's budget, despite new figures showing the economy is booming again.
The Central Statistics Office says growth in the first six months of the year was 6.7% higher than in 2014.
Ministers have also been warned they need to make choices as all of their demands cannot be met.
The GDP figures from the CSO show the Irish economy growing at levels not seen since the height of the boom.
Ireland's economy is now growing at a rate every three months that is more than the rest of Europe is seeing in a year.
However, the Government was quick to dampen down demands for a giveaway budget in advance of the election.
The Taoiseach is insisting the recovery remains fragile and a maximum of €1.5bn extra will be allocated in next month's budget.
He said: "People are concerned that poiliticians might blow this in terms of populist opportunities.
"We are not going to do that, we are not going to put the country in hock."
As his party gathered in Limerick for the annual think-in before the Dáil returns, Enda Kenny was also keen to warn his Ministers to live within their means, saying they will have to make choices based on what is available to them.
He has also told TDs and Senators that the message for the election will be that people have a choice between the current Government or chaos.
