In a recent interview with Tax Analysts, Pascal Saint-Amans, director of the OECD’s Centre for Tax Policy and Administration, was asked how concerned he was that the UK will end up going the tax haven route following withdrawal from the EU. He said:
“The U.K. wants companies to pay taxes — not much tax, because they want to be very competitive, and they have a very competitive system. Now, can they go much further in [terms of] competitiveness? Yes, they may cut their taxes a bit more, but there’s not much room [that] would drive dramatic change. The margin for slashing taxes is very limited because their taxes are already pretty low.”
So, not that concerned it would seem.
