I know people who have had these done and they look at everything, what you submit, what your accountant puts through etc. Both you are your accountants work. But what exactly are they going to find if you havent done anything wrong. Yes you are repsonsible for this, but just a vote, how many have had this done, or been caught out. If oyu have, what did you loss, dayts wage etc, and how long did it take to resolve.
