The Auditor’s Office communicated the results of the testing to Motor Vehicle management for resolution. Furthermore, the Auditor’s Office has shared the IDEAScript and trained the Tax Office’s internal audit group to perform some of the same analytical procedures. This monitoring process has assisted in the detection and correction of errors and continues to provide Tax Office management areas of training and improvement that are needed.
Tarrant County was not alone in its struggle to analyze hundreds of thousands of transactions each week. The Auditor’s Office has shared the IDEAScript and new processes with fellow Counties including the Dallas County Tax Department and Travis County Internal Audit.
Travis County Tax Office auditors are using IDEA to sort files provided by the DMV to look through transactions, including the supporting documents. Auditors can compare data year-to-year to review trends over time, perform time analysis, and compare vehicle records against a national database of vehicle identification records (VINs) to search for inaccuracies and potential fraud.
With an automated process in place, Texas County Auditors have reduced the frequency of necessary reviews, and improved the accuracy of all transactions and corresponding records.
