I shall keep this post short for otherwise it risks developing into a book. In a week which also saw the Panama papers blow a hole in the use of tax havens for individuals, the collapse of the Pfizer Allergan merger may be the beginning of the end for the Irish (and similar) corporate tax Nirvana. The US treasury’s new rules on outgoing corporate mobility mean re-incorporation in Ireland has become an awful lot less attractive.
I realise there are caveats and one may be comparing cheese and chalk. Also, tax lawyers no doubt will have to chew over this, yet: may this not also be the moment for the EC to reconsider similar issues in EU law, kicked off some time back by the Daily Mail case?
