Exemptions & appeals

View exemption application (opens in a new tab)
Exemption filing

April 30, 2026 for most 2026 exemption and special-appraisal applications; residence homestead applications may be filed late as allowed by Texas Tax Code §11.431.

Senior relief

For 2026, a qualifying owner age 65 or older (or disabled) receives the mandatory additional $60,000 school-district residence-homestead exemption; a taxing unit may also adopt a local-option exemption of at least $3,000. The owner may qualify for a school-tax ceiling/freeze and tax deferral; eligibility, local options, and documentation are administered by the local CAD.

Valuation limits

Texas 2026 rule: a qualifying residence homestead's appraised value is generally limited to the lesser of market value or the prior appraised value plus 10% and new improvements (Tax Code §23.23). The temporary circuit-breaker limit for non-residence-homestead real property valued at $5,320,000 or less is generally 20% plus new improvements and expires December 31, 2026; special agricultural/open-space appraisal uses the separate 2026 10.00% productivity cap rate.

For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
