To determine the extent of information available concerning the number and outcomes of abuse allegations received and investigated by IRS, OIG, and DOJ, we interviewed officials from the respective organizations and reviewed documentation relative to their information systems. We were told that the information systems maintained by these organizations do not include specific data elements for alleged taxpayer abuse. We cannot determine the adequacy of these controls because IRS officials have not yet established a capability to capture management information, which is needed to ensure that abuse is identified and addressed and to prevent its recurrence. Such a system has the potential to greatly improve IRS’ controls to protect against taxpayer abuse and better ensure that taxpayers are treated properly. Extent of Taxpayer Abuse Not Distinguishable in IRS, OIG, and DOJ Information Systems

It is not possible to readily determine the extent to which allegations of taxpayer abuse are received and investigated from the information systems maintained by IRS, OIG, and DOJ. The Role of the Treasury OIG in Investigating Taxpayer Abuse Allegations

OIG is responsible for investigating allegations of misconduct and waste, fraud, and abuse involving senior IRS officials, GS-15s and above, as well as IRS Inspection employees. OIG officials are to assess the adequacy of IRS’ actions in response to OIG investigations and referrals as follows: (1) IRS is required to make written responses on actions taken within 90 days and 120 days, respectively, on OIG investigative reports of completed investigations and OIG referrals for investigations or management action; (2) OIG investigators are to assess the adequacy of IRS’ responses before closing the OIG case; and (3) OIG Office of Oversight is to assess the overall effectiveness of IRS Inspection capabilities and systems through periodic operational reviews. IRS has recently established a definition for “taxpayer complaints” and is now committed to establishing a complaints tracking process.
Why GAO Did This Study

Pursuant to a congressional request, GAO examined the: (1) adequacy of the Internal Revenue Service's (IRS) controls to protect against abuse of taxpayers; (2) extent of information available concerning abuse allegations received and investigated by IRS, the Department of the Treasury Office of the Inspector General (OIG), and the Department of Justice (DOJ); and (3) OIG role in investigating abuse allegations.

What GAO Found

GAO found that: (1) the adequacy of IRS controls against taxpayer abuse is uncertain because IRS does not have the capability to capture management information on taxpayer abuse; (2) IRS is establishing a tracking system to handle taxpayer complaints and reviewing its management information systems to determine the best way to capture relevant information for the complaint system; (3) the tracking system will enable IRS to better identify instances of taxpayer abuse and ensure that actions are taken to prevent their recurrence; (4) IRS is improving controls over its employees' access to computerized taxpayer accounts, establishing an expedited appeals process for some collection actions, and classifying recurring taxpayer problems by major issues; (5) it is not possible to determine the extent to which allegations of taxpayer abuse are received and investigated, since IRS, OIG, and DOJ information systems do not include specific data elements on taxpayer abuse; (6) OIG has increased the number of investigations involving senior IRS employees' alleged misconduct, fraud, and abuse; (7) OIG refers most of these allegations to IRS for investigation and administrative action; and (8) IRS is taking a considerable amount of time to respond to OIG investigations and referrals regarding senior IRS officials' disciplinary actions.
