There is a projected surplus of about 25 billion euro this year, according to figures from the Department of Finance.
The figure was announced by Finance Minister Jack Chambers ahead of the publication of the White Paper which deals with estimates of receipts and expenditure for the year.
The figures do not include measures to be announced in the Budget on Tuesday.
Mr Chambers revealed that approximately 8 billion euro of the 14.1 billion euro Apple taxes will be received by the Exchequer in 2024, with the remainder due in 2025.
He said he is working with Public Expenditure Minister Paschal Donohoe on a proposal for party leaders relating to a “wider strategic direction” for the Apple tax, rather than specific spending decisions.
He said the parameters for using the money will be set out in the Budget.
The Apple receipts mean that, on a pre-Budget basis, the department is projecting a general government surplus of about 25 billion euro for 2024, and 12 billion euro for 2025.
This is the equivalent of approximately 8% of GNI* for 2024 and 3.75% for 2025.
Modified gross national income (GNI*) attempts to give a better view of the Irish domestic economy by removing some multinational activity, compared with the standard metric of gross domestic product (GDP), which is the value of goods and services produced in a country.
Speaking at the Department of Finance on Friday, Mr Donohoe said the economy “continues to perform very strongly”.
The Summer Economic Statement (SES), published in July, set out the parameters for a Budget worth 8.3 billion euro, with spending measures of 6.9 billion euro and a tax package worth 1.4 billion euro.
Mr Donohoe said the White Paper does not change these parameters and budgetary negotiations continue on the SES basis.
Asked about corporation tax levels, Mr Chambers said receipts are 28% ahead of last year which is “far in excess” of projections.
Overall corporation tax receipts are expected to be 30 billion euro this year.
“They’re performing really strongly and that’s why its important with additional windfalls around corporation tax that we’re very careful in our management of that,” he said.
Mr Chambers told reporters he did not expect the Budget’s cost-of-living package to be of the same scale as last year, given that inflation is just over 1%.
However, he acknowledged there was still an impact of high prices from underlying inflation.
Separately, Mr Chambers said he “would try and advance” a tax on vapes in the Budget.
