A theoretical possibility, certainly. Meanwhile, the reality is that this is being done systematically today using the tax regimes of Ireland, Holland and Luxembourg. Why do you think that Kikkonen sited themselves in the Netherlands? According too their corporate spiel, their breakthrough and initial presence in Europe was in Germany, not the Netherlands. But profits earned in Germany can’t exit the EU with it consideration of a withdrawal tax.One of the Govt's hope for Brexit is that if it allows companies to not pay taxes here, they will offshore profits from the EU to avoid paying taxes there.
This is what the EU does — what it was designed to do. Companies have access to the entire EU marketplace so long as they are based somewhere in the EU. So they can set up nice complex structures to avoid tax whilst still being able to trade in an uninhibited fashion across the entire economic marketplace.
