Part 5 of the Finance Act 2013 makes provision for the General Anti-Abuse Rule (GAAR). In particular, it allows for arrangements that are thought to be abusive to be referred, in some circumstances, to the GAAR Advisory Panel. Schedules 43A and 43B to that Act set out a procedure under which, where one set of arrangements is referred to the Panel (the “lead arrangements”), equivalent arrangements can also be counteracted.
