We all recognise the need to strike a balance between what we want and what we can afford. In some cases this can be a relatively easy exercise, in other situations, it’s more complicated. Take for example reform of the Controlled Foreign Companies (CFC) rules, where the Government’s aim of creating the most competitive tax system in the UK must be balanced with protecting tax revenues. Clearly, this is no easy task, as the 109-page consultation document issued by the Treasury in June 2011 proves.
