Per the Texas Comptroller, the appraised home value for a homeowner who qualifies his or her homestead for exemptions in the preceding and current year may not increase more than 10 percent per year.
Tax Code Section 23.23(a) sets a limit on the amount of annual increase to the appraised value of a residence homestead to not exceed the lesser of:
Tax Code Section 23.23(e) defines a new improvement as an improvement to a residence homestead made after the most recent appraisal of the property that increases its market value and was not included in the appraised value of the property for the preceding tax year. It does not include repairs to or ordinary maintenance of an existing structure, the grounds or another feature of the property. Tax Code Section 23.23(f) states that a replacement structure for one that was rendered uninhabitable or unusable by a casualty or by wind or water damage is also not considered a new improvement.
The appraisal limitation only applies to a residence homestead. As stated in Tax Code Section 23.23(c), the limitation takes effect Jan. 1 of the tax year following the year in which the homeowner qualifies for the homestead exemption. It expires on Jan. 1 of the tax year following the year in which the property owners no longer qualify for the residence homestead exemption.
If an ARB, arbitration or court determination lowered a property’s appraised value, the appraisal district cannot increase the appraised value unless the increase is reasonably supported by clear and convincing evidence.
