Re: "the country has an advantageous business and digital tax environment"
For Ireland (the whole Island) and since they currently have 2 regimes as I already pointed out it wouldnt be hard.
Two different countries. Two different legal systems.
"You can only have one regime. They're sticking with the in EU regime and prospering."
Who is? You mean the buggered by the EU proper Ireland who required bailing out because of the Euro booming their economy then shafting it? Oh the prosperity. And the Apple case with the tax issue shows loss of sovereignty under the EU. Losing so much but you go ahead and call it a win. Say the same for Greece while your at it.
Ireland, Greece, Portugal and Italy all made the same mistake - borrowing on the bond market to fund short-term political game. It came back to bite them. If they had their own currency, they could have devalued, just like Britain did in the 1960s but because they didn't, their political malfeasance got brought into the light that much more clearly.
"Business is moving from the UK to Ireland because Ireland stays in the EU and the UK is leaving."
Did it say moving? The article is pretty clear- Gurvan said sales over the next two quarters, and of course the transition period, would show if the growth was solely Brexit-related. But ok lets say they are brass plating or meeting the minimum EU requirements.... you think such isolationism is a good thing? How does that work out?
What is Brexit if it isn't a form of isolationism, creating artificial trade barriers between the UK and its biggest trading partner? Given that UK businesses already meet EU requirements, what with the UK being in the EU, moving to Ireland (that accursed freedom of movement!) means they get to stay in the EU.
Business will move where the money is. It would appear that Brexit, in their opinion, means the money isn't in Britain right now.
