(1) The reappraisal cycle for class three and four property is January 1, 2015, through December 31, 2016. The department will accept requests for informal classification and appraisal reviews (Form AB-26) for class three and class four property for tax years 2015 and 2016. The reappraisal cycle for class ten property is January 1, 2015 through December 31, 2020. The department will accept Form AB-26 requests for class ten property for tax years 2015 through 2020. A property taxpayer who is dissatisfied with their property's appraised value may submit a Form AB-26 one time per reappraisal cycle. The Form AB-26 must be submitted to the local department office in the county in which the property is located within 30 days after the date on the classification and appraisal notice to be considered for the current tax year.

(2) For taxpayers who do not file within 30 days after the date on the classification and appraisal notice, the informal review will be considered for the following year.

(3) Any adjustments to taxable value will be reflected only in the tax year timely filed and ensuing years. There will be no retroactive adjustments to the taxable value for years prior to the accepted filing date.

(4) For subsequent reappraisal cycles, beginning in tax year 2015, taxpayers may file an informal classification and appraisal review in any year of the cycle, but only one time during a cycle unless the department determines that a change in value occurred and the taxpayer receives a new classification and appraisal notice during the cycle.
