Tax Code §23.57

(a) The chief appraiser shall determine separately each applicant's right to have the applicant's land appraised under this subchapter. After considering the application and all relevant information, the chief appraiser shall, as soon as practicable but not later than the 90th day after the later of the date the applicant's land is first eligible for appraisal under this subchapter or the date the applicant provides to the chief appraiser the information necessary for the chief appraiser to determine the applicant's right to have the applicant's land appraised under this subchapter, 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 requires additional information from an applicant, the chief appraiser shall, as soon as practicable but not later than the 30th day after the date the application is filed with the chief appraiser, deliver a written notice to the applicant specifying the additional information the applicant must provide to the chief appraiser before the chief appraiser can determine the applicant's right to have the applicant's land appraised under this subchapter. The applicant must furnish the information not later than the 30th day 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, the chief appraiser shall deliver a written notice of the denial to the applicant not later than the fifth day after the date the chief appraiser makes the determination. The notice must state and fully explain each reason the chief appraiser denied the application. The notice must include a brief explanation of the procedures for protesting the denial.
