Taoiseach Enda Kenny has promised over 10,000 public service jobs if he is returned to office.
The Labour Party, meanwhile, has said it will abolish the Universal Social Charge for those earning less than €72,000.
Fianna Fáil has described Minister for Finance Michael Noonan's plan to do away with the measure altogether as a "runaway tax cut".
Mr Kenny said Fine Gael in government would provide over 10,000 extra public service jobs, including over 3,000 teachers, 2,800 nurses and 1,800 gardaí.
Meanwhile, Labour has promised a job for all by 2018, the removal of the USC from those earning less than €72,000 and a living wage of €11.30 an hour.
Tánaiste Joan Burton said the USC change would deliver very significant benefits for low and middle-income earners.
At the same time, the party would reduce the burden on the low-paid through adjustments of the PRSI system.
The Tánaiste attacked Sinn Féin saying: "I want to call out Sinn Féin to actually set out what their proposals are. Sinn Féin are ducking and diving."
Sinn Féin's finance spokesman Pearse Doherty said that if he is finance minister in the next government, his first priority will be to give families a break, including those who are self-employed, by abolishing the Local Property Tax, ending water charges and taking a further 277,000 workers out of the USC.
Fianna Fáil said its economic plan would be prudent and costed and would be approved by an international firm of experts.
The party is proposing to spend €8.3bn over five years, split two to one between spending and tax cuts.
The party would do away with the USC on salaries up to €80,000 a year.
Fianna Fáil said the Fine Gael plan which would abolish the measure entirely would be a "runaway tax cut" conferring limitless benefits on the better off.
Sinn Féin will launch its manifesto tomorrow. Party leader Gerry Adams is canvassing in Dublin again this afternoon.
96 candidates support Right2Change principles
Meanwhile, 96 candidates running in the General Election have signed up to the Right2Change principles.
At the launch of those principles today, Brendan Ogle of the Unite trade union said the policy platform offers a "real alternative".
The principles include the abolition of Irish Water within 100 days of a new government and the guarantee of a single utility through a referendum.
The group has also produced a fiscal strategy which would see €6bn of investment in water.
Sinn Féin deputy leader Mary Lou McDonald, who was the only party political representative at the Right2Change news conference, said there is "substantial common ground" among the candidates who have signed up to the principles.
She said there was an unparalleled phenomenon in the State where people who had never protested before took the decision to "take a stand" and said this election would be one where "all of that crystallises".
