The Taxpayer Service Division contributes to the Internal Revenue Service mission of achieving the highest possible voluntary compliance with the Federal income tax law by answering questions and helping taxpayers in their return preparation efforts. These services are provided by Taxpayer Service Representatives and Taxpayer Service Specialists (TSS's). The TSS position was established in 1975 to upgrade the quality of assistance provided. TSS duties include being able to provide assistance with problems involving complex areas of the tax law. The purpose of the study was to disclose to what extent TSS's are called on to answer tax questions related to partnerships, corporations, and Subchapter S corporations and to disclose whether they have been trained and are able to answer the inquiries.

The purpose of this thesis was to analyze a number of auditor change and other peripheral issues from two related perspectives. Empirical data were gathered from publicly available Forms 8-K and 10-K to first assess whether meaningful differences existed between NYSE, AMEX, and OTC registrants regarding disclosures required in those documents. Secondly, the data were analyzed to determine whether differences existed with respect to the accounting firms (Big Eight or non-Big Eight) involved in the auditor changes. In most of the tests designed to achieve these purposes, statistically defensible results were obtained using the nonparametric chi-square test for significance of observed differences and the McNemar test for significance of changes, at the .05 level.
