If you want to make a complaint about your accountant/auditor or a firm of accountants/auditors, you should initially contact the Prescribed Accountancy Body (‘PAB’) of which the accountant/auditor/firm is a member. Please click here for contact details for the PABs.
If the complaint relates to the audit of a Public Interest Entity (PIE), you should refer your complaint directly to IAASA – http://www.iaasa.ie/contact
