The duties of the appraisal district include:
- The determination of market value of taxable property
- The administration of exemptions and special valuations authorized by the local entities and the State of Texas
The San Augustine County Appraisal District appraises property for ad valorem taxation of these taxing authorities.
Tax rates and ultimately the amount of taxes levied on property are determined by governing bodies of each of the taxing authorities.
Mineral, utility and industrial accounts are appraised for the district by Pritchard & Abbott, Inc. in Houston, Texas.
