The Department of Finance has released its estimates for receipts and expenditure for 2013 , ahead of Budget Day next Wednesday.
The figures show that tax revenue for 2012 is expected to fall €210m below the target of €36.375bn.
However, the Department of Finance said that the budget deficit is expected to be ahead of target at 8.2% of GDP by the year's end.
Fianna Fáil spokesperson on finance Michael McGrath has accused the Government of making an all-out assault on families in the upcoming Budget.
"I am very concerned about what I am hearing by way of leaks from the Cabinet meetings that the g really seems to be determined on an all-out assault on families," he said.
