Taoiseach Leo Varadkar has promised a five-year income tax cut if Fine Gael wins the next election.
When talks about extending the life span of the minority government into the fourth week, Mr Varadkar massively raised his stakes.
He used Ard Fheis's televised speech to turn on Fianna Fail, saying that they were "not easy" to negotiate.
"We know what we inherited from Fianna Fáil – bankrupt banks cannot lend, ghosts, Pyrite, Mica, Priory Hall, hundreds of thousands of people in negative equity, mortgage arrears, and hundreds of thousands of construction workers on that charity," he said.
But most of the attention focused on the big promise to reduce income tax rates for middle income families.
Mr Varadkar said "the frivolous mismanagement of the past is unfair to all".
"This has resulted in hundreds of thousands of jobs being lost, public services being cut, taxes going up and future generations burdened with huge national debt."
He claimed Fine Gael had succeeded in reversing many injustices "but some elements survived".
"For example, the average income earner in Ireland pays the highest tax. Full-time income on average is almost € 46,000 but in Ireland we pay the highest tax rate of just over € 35,000.
"This makes parents reluctant to return to the world of work, does not encourage people who emigrate from returning home, and makes it harder to attract good jobs and talent to Ireland."
Taoiseach said the current tax rate – which sees workers paying 40pc tax at recipients of more than € 35,300 – "is holding our country back".
"Fine Gael will put an end to that injustice. But we will not do it in a big dramatic move – we have learned from Fianna Fáil's mistakes. We will do it in a sustainable and affordable way.
"During the last 3 budgets, Fine Gael and Independents in Government have increased the point where people pay higher tax rates, but we have to go further now," Varadkar said.
He then promised: "So, over the next five budgets, we will commit to increasing the point where people pay the highest tax rate of up to € 50,000 for one person or € 100,000 for two couples on income.
"We will end this injustice and allow people who work hard to save more of the money they earn."
This move will likely get an attack from the Opposition parity which will see it as a reminder of the Celtic Tiger years.
Mr Varadkar touched on the crisis in housing and health in his speech.
Regarding housing, he said: "Fine Gael firmly believes that every family must have a roof over their heads, a place to call home.
"Fine Gael is the owner of the house. And now it's our mission to ensure that home ownership is achievable and affordable for many people who feel that they are beyond their reach.
"Years of housing crisis and maybe decades of making it."
Regarding health, Mr Varadkar said: "We live longer and are healthier than before.
"Today more people survive cancer than die. And survival rates for strokes and heart attacks also increase.
"The waiting time for operations and procedures will decrease.
"These things are not just coincidences. They are a direct result of Government policies and strategies, Government expenditures and resources, and the professionalism and quality of our health care staff.
"Now we need more, especially when it comes to problems that seem difficult to solve like crowded hospitals."
Meanwhile, Micheál Martin has criticized Taoiseach Leo Varadkar's tax cuts – urging Fine Gael to "cool the jet" on promises of election tax.
The parties disputed about when a review of the Confidence Agreement and Supply had to end the renegotiation must begin and speculation about the immediate election had been increased by the key Taoiseach address at the party's Ard Fhéis.
Mr. Martin urged caution and claimed that the promise could cost up to € 4 billion. He said the pledge was reminiscent of what was made before the last General Election.
"Remember the last General Election … & # 39; US-style tax and we will eliminate Universal Social Charge (USC) & # 39 ;?
"It was a promise of € 4 billion left as soon as they entered the government … so the jet chilled in terms of the tax promise of Fine Gael.
"It was the election platform speech … and once again there was no charge attached to it."
At Citywest Fine Gael is eager to declare that they are ready for elections. In response, Martin said all parties were ready for the election.
But he tried to play down the prospect of the country going to the polls in a snap election saying:
"The only people who create an aura of instability around the government are the government itself, especially Leo Varadkar."
Martin said it was clear some ministers, including Simon Harris, were interested in the election but once again reiterated the need to avoid elections until the Brexit agreement was ratified.
"I cannot explain the kind of youth behavior of ministers today," he said of various statements made by senior Fine Gael members who urged that talks on a new agreement should begin.
Martin also said the Government was unprepared for no Brexit agreement but said that there was "some distance" yet to enter the British parliament in relation to getting an agreement through parliament, expressing optimism that the agreement was agreed between Britain and Britain.
