SINN Fein has accused the Government of hitting low- and middle-income families in the Budget.
Finance spokesman Pearse Doherty criticised the rise in workers' PRSI, child benefit cuts and the property tax.
"Your family home tax will be the straw that breaks many families' backs," he said.
Mr Doherty quoted Taoiseach Enda Kenny's previous words while in opposition that a property tax was "morally wrong, unjust and unfair".
And he dismissed the proposal to allow people to delay paying the tax if they were in financial difficulty. "You are going to charge them 4pc for the luxury of deferring it," he said.
He said that scrapping the PRSI-free allowance for workers would raise €289m whereas his party's plan for a 48pc rate of income tax on incomes greater than €100,000 would have raised €385m.
Mr Doherty criticised the Government's decision to tax maternity benefit, saying it came just a few weeks after the children's referendum. "You want to tax children before they are even born," he said.
Sinn Fein submitted its own alternative budget of €2.7bn in extra taxes and €1bn in savings, although it wasn't costed by the Department of Finance.
