AUDIT SCOPE AND METHODOLOGY Our audit scope was to examine the program and other records of the Motor Fuel, Cigarette and Miscellaneous Taxes Division for the period October 1, 1991 through September 30, 1994. Our audit was conducted in accordance with Government Auditing Standards issued by the Comptroller General of the United States and, accordingly, included such tests of the records and such other auditing procedures as we considered necessary in the circumstances. Our audit methodology included analysis of the program activity for each of the various taxes administered by the Division. This analysis included review of the internal control structure and the management practices over the licensing operation, the receipting and recording of tax reports, the auditing of tax returns, the assessment of tax deficiencies, and the refunding of overpayments of taxes. Also, we reviewed procedures used in the determination of surety bond requirements. In addition, we tested controls over licensing, surety bonds, refunds, the recording of tax revenue, and the auditing of tax returns.

AGENCY RESPONSES AND PRIOR AUDIT FOLLOW-UP Our audit report contains 4 findings and recommendations. The agency preliminary response indicated that the Division either had taken steps or will take action to comply with all the recommendations.

The Division had complied with the 11 prior audit recommendations included within the scope of our current audit.
