The Public Expenditure Minister is warning Ireland's high corporate tax levels may not be sustained.
Latest Exchequer figures show more than €16 billion in corporate tax receipts were collected up to the end of October, €6 billion more than the same period last year.
There was also strong growth in income tax and VAT last month.
However, Minister Michael McGrath says there's a danger Exchequer figures may not be repeated in the future.
