Here's a critique of the UK database entries of our Financial Secrecy Index, from a lawyer at Clifford Chance - one of the world's ten biggest law firms (per Wikipedia). And what follows is a response on the points raised.
To begin, we really value expert feedback. We had a nearly two-year review process before the Jan.2018 release, which we were delighted to find brought in a great many stakeholders, including experts, users and subject jurisdiction policymakers..
1. Are advanced tax rulings just a mechanism to corrupt the normal application of tax rules to multinational companies? (A quick thread as work avoidance)
2. The attraction, on paper, is that multinational companies get certainty about (some) tax treatment; as do tax authorities, who can then focus their limited resources elsewhere.
3. The risks? That the negotiation over advanced tax rulings is even more unbalanced than the usual negotiation over multinationals' actual tax payments. The tax authority has no threat of demanding audit or payment; and cannot devote the same level of resources.
