Aah, KPMG! I once worked on secondment for a large corporate in Oz. Each year my company contracted KPMG to file all UK employees' tax returns with the Oz taxman. Mine was very straightforward; and I earned less than 50K - KPMG raked in £1200 for the privilege! My boss's was a little more complicated (due to his share options and bonuses!) - KPMG felt able to up his charge to around £4000. On the odd occasion I had to ask for KPMG help with a related tax issue, they were v difficult to find. Good outfit.
