“On the fiscal side, we are projecting a headline surplus of €8.6 billion for this year, the equivalent of 2.8 per cent of national income. This is based on the assumption of tax revenue amounting to almost €92.1 billion, a growth rate of 4.6 per cent. However, I would caution that this surplus is heavily dependent on volatile ‘windfall’ corporate tax receipts which have grown from €4 billion to €24 billion in the space of a decade. When the windfall element of these receipts – estimated at around €11 billion, or almost half the projected corporation tax yield this year – is excluded, there is an underlying deficit in our public finances.
