Figures from the Department of Finance show that tax receipts for the first five months of the year are just behind Government targets.
The latest Exchequer figures show that total tax receipts amounted to €12.117bn for the five months to the end of May.
That is 1.2% lower than the Government's forecast figure of €12.265bn. It is also down 10.4% on the same time last year.
Today's figures also show the Government had a deficit of €7.867bn for the five months to the end of May, down from the €10.588bn at the same time last year.
The Department of Finance said: 'This is generally inline with expectations and means that Budget Day targets remain valid.'
It also said the annual difference in the Exchequer deficit is mainly due to payments to the National Pensions Reserve Fund.
A payment of €3bn was made into the fund in May 2009 but no such payment was due this year.
Breaking down the figures, they show that Capital Gains tax came in 32% higher than Government forecasts at €111m, while Capital Acquisitions Tax beat forecasts by almost 17%.
VAT was marginally ahead of forecasts at €4.87bn, while Corporation Tax was also 3% higher than originally predicted at Budget time at €748m.
However, income tax fell 4.9% short of targets, amounting to €4.2bn.
Stamp Duty was over 14% lower than Budget predictions, coming in at €244m for the five-month period.
