It's been confirmed that the tax take for the first 11 months of the year is almost €3 billion ahead of target.
The booming exchequer returns come after a huge surge in corporation tax, most of which should be repeated next year.

The good figures mean the state will probably be able to stop borrowing in 2017 - a year ahead of schedule.
However the news comes on the same day as the health service is given a so-called 'supplementary estimate' - in reality, a bailout - of €665 million.

Today's news means the government has now sanctioned €1.2 billion in extra end-of-year spending for state agencies and departments, with more potentially to follow.
