Tax Code §23.57

(a) The chief appraiser shall determine separately each applicant's right to have his land appraised under this subchapter. After considering the application and all relevant information, the chief appraiser shall, as the law and facts warrant: (1) approve the application and allow appraisal under this subchapter; (2) disapprove the application and request additional information from the applicant in support of the claim; or (3) deny the application. (b) If the chief appraiser requests additional information from an applicant, the applicant must furnish it within 30 days after the date of the request or the application is denied. However, for good cause shown the chief appraiser may extend the deadline for furnishing the information by written order for a single period not to exceed 15 days. (c) The chief appraiser shall determine the validity of each application for appraisal under this subchapter filed with him before he submits the appraisal records for review and determination of protests as provided by Chapter 41 of this code. (d) If the chief appraiser denies an application, he shall deliver a written notice of the denial to the applicant within five days after the date he makes the determination. He shall include with the notice a brief explanation of the procedures for protesting his action and a full explanation of the reasons for denial of the application.
