Have you ever wondered what is in your Revenue file? The Freedom of Information (FOI) Act 1997 means that you have a legal right to have access to information held by public bodies which affects you. The Revenue says it already makes such information available. Under Section 16 of the Act its rules, procedures, practices, guidelines interpretations and precedents have been compiled in CDRom format and are available from all tax offices to you or your tax adviser at a cost of £15.
