I’d draw attention to some articles I wrote about Barclays.
All suggestion the legal and ethical underpinning that could make a Banking Code on tax viable.
These dealt with the need for a change in the way the law on tax is interpreted. I argue we do not need to be constrained by 19th century thinking.
We also need a general anti-avoidance principle.
Lastly, we need a robust and public code for all companies, and government. I have drafted such a Code for the Tax Justice Network and for the Association for Accountancy and Business Affairs in 2007. This is available here.
And before you dismiss the thinking I’d advise you that those drafting the Banking Code are familiar with what I think – I’ve presented this stuff to them at their request. They have copies.
