(a) An individual claiming the right to have his land designated for agricultural use must apply for the designation each year he claims it. Application for the designation is made by filing a sworn application form with the chief appraiser for the appraisal district in which the land is located.
(b) A claimant must deliver a completed application form to the chief appraiser before May 1 and must furnish the information required by the form. For good cause shown the chief appraiser may extend the deadline for filing the application by written order for a single period not to exceed 60 days.

(c) If a claimant fails to timely file a completed application form in a given year, he may not receive the agricultural designation for that year.
(d) The comptroller in prescribing the contents of the application forms shall ensure that each form requires a claimant to furnish the information necessary to determine the validity of the claim. The comptroller shall require that the form permit a claimant who has previously been allowed an agricultural designation to indicate that previously reported information has not changed and to supply only the eligibility information not previously reported. The form must include a space for the claimant to state the claimant’s date of birth. Failure to provide the date of birth does not affect a claimant’s right to an agricultural designation under this subchapter.
(e) Before February 1 the chief appraiser shall deliver an application form to each individual whose land was designated for agricultural use during the preceding year. He shall include with the application a brief explanation of the requirements for obtaining agricultural designation.
(f) Each year the chief appraiser for each appraisal district shall publicize, in a manner reasonably designed to notify all residents of the district, the requirements of this section and the availability of application forms.
