New figures show the Government has taken in nearly €500m more than expected in taxes in the first four months of the year.
Exchequer returns published this evening show an extra €475m collected compared to Budget Day predictions, 3.5% above target.
Most of the extra money is from higher-than-expected corporation tax and excise duty driven by new car sales and sales of tobacco products.
Non-tax revenues were boosted by an earlier than expected payment from the Central Bank of €1.8bn in surplus income.
Spending by the Department of Health had overrun by €78m, but spending by all other Departments was at, or below, budget.
