I have been informed by the Revenue Commissioners that it is their policy to inquire into all information received concerning alleged tax evasion, including anonymous information. Such information is initially evaluated for relevance and quality and, where possible, steps are taken to validate it before follow up action is taken. Follow up action would include the initiation of an audit or investigation if the information about alleged tax evasion appeared to be valid.
The Deputy's question seems to link the follow-up by Revenue in relation to information supplied by citizens with revelations about taxation matters at tribunals of inquiry. The Revenue Commissioners advise me that, if this is so, it is not clear what reports or information the Deputy may have in mind and that there has been no failure to act on information received in regard to high profile cases or indeed any cases involved in tribunals. If the Deputy is aware of specific information in this regard he should of course bring it to the attention of the Revenue Commissioners.
The investigation of cases in the office of the chief inspector of taxes, whether initiated on the basis of information received or otherwise, can take, in some cases, a considerable period of time. This can be due to a variety of factors such as the size and complexity of a case, the level of co-operation received from the taxpayer or his advisers, whether application has to be made to the courts for information disclosure orders, whether prosecution has to be considered, the length of time taken up by the appeal process and the time required to enforce collection. The Revenue Commissioners assure me that audits and investigations are completed in the shortest possible time.
