Revenue are responsible for producing the information and enforcing compliance. On many phone calls to them I've often failed to be given the correct information from staff on the phone.... I have however been given lots of incorrect information on what steps to take that I would consider, seeing as it was no way related to the revenue documents, to be the personal "advice" of the person on the other end.Revenue dispense information not advice.
Had I not found the documents and looked through them for myself I would have assumed the details given to me by the staff was the "information" and not just that member of staffs opinion.
Again, not intentional, but had it been followed it would have left my tax affairs out by a fairly large chunk more than once (both over and under payments).
