The tax take for the first three months of the year is almost 5% ahead of the same time last year.
The Exchequer figures for the first quarter show €9.2bn was collected.
The Budget deficit at the end of March stood at just over €2.3bn, €1.4bn lower than the same time in 2013.
The Department of Finance says there has been a solid start to the year.
The €9.2bn figure is almost 3% ahead of projections and 4.7% or €415m more than tax revenue during the first quarter of 2013.
Income Tax is up by 3.5%, VAT increased by 6.4% year-on-year, driven by strong retail sales, and excise duties are up 11.5%.
Public spending is down by just under 6% or €631m at €10.2bn.
However, spending in the Department of Health is already 1.5% over budget after the first three months of the year.
