Dear Mr. George:


We have reviewed the system of quality control for the audit organization of Treasury Inspector General for Tax Administration (TIGTA) in effect for the year ended March 31, 2015.  A system of quality control encompasses TIGTA's organizational structure and the policies adopted and procedures established to provide it with reasonable assurance of conforming with Government Auditing  The elements of quality control are described in Government Auditing Standards.  TIGTA is responsible for establishing and maintaining a system of quality control that is designed to provide TIGTA with reasonable assurance that the organization and its personnel comply with professional standards and applicable legal and regulatory requirements in all material respects.  Our responsibility is to express an opinion on the design of the system of quality control and TIGTA's compliance therewith based on our review.


Our review was conducted in accordance with Government Auditing Standards and the Council of the Inspectors General on Integrity and Efficiency Guide for Conducting Peer Reviews of the Audit Organizations of Federal Offices of Inspector General.  During our review, we interviewed TIGTA personnel and obtained an understanding of the nature of the TIGTA audit organization, and the design of TIGTA's system of quality control sufficient to assess the risks implicit in its audit function.  Based on our assessments, we selected audits and administrative files to test for conformity with professional standards and compliance with TIGTA's system of quality control.  The audits selected represented a reasonable cross-section of TIGTA's audit organization, with emphasis on higher-risk audits.  Prior to concluding the peer review, we reassessed the adequacy of the scope of the peer review procedures and met with TIGTA management to discuss the results of our review.  We believe that the procedures we performed provide a reasonable basis for our opinion.



1 Issued by the Comptroller General, December 2011


In performing our review, we obtained an understanding of the system of quality control for the TIGTA audit organization.  In addition, we tested compliance with TIGTA's quality control policies and procedures to the extent we considered appropriate.  These tests covered the application of TIGTA's policies and procedures on selected audits.  Our review was based on selected tests; therefore, it would not necessarily detect all weaknesses in the system of quality control or all instances of noncompliance.


There are inherent limitations in the effectiveness of any system of quality control, and, therefore, noncompliance with the system of quality control may occur and not be detected.  Projection of any evaluation of a system of quality control to future periods is subject to the risk  that the system of quality control may become inadequate because of changes in conditions, or because the degree of compliance with the policies or procedures may deteriorate.


Enclosure 1 to this report identifies the TIGTA offices that we visited and audits that we reviewed.


In our opinion, the system of quality control for the audit organization of TIGTA in effect for the year ended March 31, 2015, has been suitably designed and complied with to provide TIGTA with reasonable assurance of performing and reporting in conformity with applicable professional standards in all material respects.  Audit organizations can receive a rating of pass, pass with deficiencies, or fail.  TIGTA has received an External Peer Review rating of pass.  As is customary, we have issued a letter dated December 11, 2015 that sets forth findings that were not considered to be of sufficient significance to affect our opinion expressed in this report.
