The Tax Code requires the Comptroller's office to prepare and publish several reports including the Appraisal District Ratio Study Report, the Biennial Report, and the Report on Cost of Property Tax Exemption for 100 Percent Disabled Veterans.
The Tax Code also requires Texas Comptroller of Public Accounts to administer several surveys and issue reports summarizing the data reported through those surveys. The Comptroller's office compiles this information to develop reports and/or publish the information on this webpage.
Tax Code Section 5.10 requires the Comptroller's office to conduct a ratio study to measure the performance of each appraisal district in Texas at least once every two years and to publish the results.
The purpose of the Appraisal District Ratio Study is to measure the uniformity and median level of appraisals performed by an appraisal district within each major category of property.
To conduct the Appraisal District Ratio Study, the Comptroller's office applies appropriate standard statistical analysis techniques to data collected through the school district property value study required by Government Code Section 403.302.
The published reports provide ratio study results for each appraisal district studied that year and includes:
