Brexit represents a conundrum for tax policy-makers. On the one hand, leaving Europe provides the opportunity to abandon EU restrictions on the UK tax system, allowing it to evolve to meet our own needs. On the other hand, with thousands of regulations to rewrite, complex negotiations to be undertaken and all of this in the context of global economic uncertainty where the UK wishes to continue to play a vital role, there is a serious risk that the opportunity to clean up the UK tax system will be missed because of lack of resources and too much busy-ness in other areas.
