Under Texas law, the County Auditor is responsible for:
* Oversight of all the books and records of all County officials
* Strict enforcement of all laws governing County finances
* Advice to Commissioners Court concerning financial conditions as they affect the decision-making process
* Administration, reporting and forecasting of the County budget as set by the Commissioners Court
* Preparation of the COMPREHENSIVE ANNUAL FINANCIAL REPORT (CAFR) and the POPULAR ANNUAL FINANCIAL REPORT (PAFR).
There are many reasons to have a County Auditor, but the main one is to maintain the integrity of financial administration in county government. Every two years, the state District judges in Williamson County appoint the County Auditor. Because the Auditor is neither appointed by nor under the hierarchical control of the Commissioners Court, the integrity of county finances is protected by a dual system of "checks and balances".
Stewards of Public Funds
The Office of the County Auditor currently consists of 25 employees acting as the "Stewards of Public Funds" in the areas of Internal Audit, Financial Accounting and Reporting, Accounts Payable and Payroll.
