The Finance Minister says a higher-than-expected budget surplus for 2023 will not be spent on 'permanent, recurring measures'.
A surplus of around €10bn is expected this year - mainly driven from corporation tax.
Revenue from corporation tax for the first three months of the year was 70 percent higher than the same period in 2022.
Finance Minister Michael McGrath says there is a possibility that a portion will be used for a rainy-day fund or on once-off projects.
"When I look at the public capital programme we have at the moment it's over 12 billion euro.
"We've had significant under spends in each of the last two years, that doesn't mean that we will have under spends in the future -- COVID played a role in that.
"But what I am saying is we will examine the potential of strategic once or for capital investment that would deliver a return for the people and for the state."
