The government is predicting an exchequer surplus of 609 million euro in 2019.
The figure is revealed in its pre-budget White Paper, which sets out expected returns up to the end of this year.
However, threats of a no-deal Brexit and hundreds of million in overruns at the Departments of Health and Social Protection has seen it abandon plans to put 500 million euro in a Rainy Day fund.
Labour leader Brendan Howlin says the fund clearly isn't working and the money now needs to be used to protect jobs.
