Exchequer figures for the first 11 months of the year show that total tax receipts are almost €2bn behind the target set out in last year's Budget.
This follows weekend estimates from the Department of Finance which showed that taxes collected this year would be around €1.75bn below target.
Today's figures show that the total tax take to the end of November was just under €44.7bn, compared with the €46.5bn target.
Stamp duty was almost €600m below expectations at just under €3bn, though income tax was almost bang in line at €12.54bn.
The take from VAT was almost €400m lower than expected at €14bn, while Corporation Tax was almost €350m behind target at €6.2bn. The take from excise was around €250m less than projected at just under €5.2bn.
Overall the Exchequer was in surplus to the tune of €1.58bn. But the Government is expecting a deficit of €1.6bn for the full year, as opposed to the €546m forecast at Budget time.
