I suppose at a fundamental level, the sun has been there for a long time and we understand why it rises, falls, and what is likely to happen in the future. To a more fiscally relevant comparison, we know we have x amount of workers we can tax, and even if unemployment spiked to the levels last seen in the great recession and emigration took off, a majority of them will still be here. We know how many houses there are and how much property tax we could levy at this level and that level.My criticism of IFAC is that their perspective is of "what if" those taxes were to disappear in the morning?
What if the Sun disappears in the morning?
We also know that if there was a recession tomorrow, once we came through the economic cycle things like employment - and associated taxes - are likely to bounce back. While if corporate tax receipts fell away due to changes in the tax environment, those revenues would not return.
The amount of corporate taxes coming to us is exceptional and not really grounded in anything in particular that is rooted here at home. The rules on IP placement could change tomorrow and we could keep the jobs but just see a smaller slice of the revenues.
There are a number of credible moves that could disrupt the current arrangement - the US regime, or a future one, EU or OECD level tax reforms - the fact we collect so much relative to our economy puts a target on our back that is quite logical from the point of view of our partners. The tax planning habits of a few corporations or, indeed, their own profit margins could all impact us.
These are decisions and things largely happening offshore, while we have baked the revenues into our day to day spending.
I disagree for the reasons set out above. There is a certain predictability to the domestic economy. I think the way to look at these receipts would be to call out what should definitely not be set against day to day current spending, because of the risk. Alas, that opportunity is now in the rearview mirror.I don't necessarily disagree with that, I just disagree with the budgeting exercise of public finances without FDI tax receipts when the same exercise could be applied to Income Tax, VAT, etc.
Another way to think about it would be, if some sensible % of the CT receipts fell away, what % of current day to day spending now relies on them and would need to be either slashed in austerity or made up by hikes in income tax. Bearing in mind that CT receipts are now almost equal the entire income tax take. And is that a sensible risk to at least call out.
