A couple of submissions have suggested using Revenue rather than creating a central processing authority, CPA. This is not an area I understand particularly well, never having been an employer at the scale in question. Mr. O'Brien says employers are used to dealing with the Revenue Commissioners. I want to give him a chance to expand on that and why he believes a CPA model might be overly cumbersome or overly costly to put in place.
