These are the dates and qualifications recorded in the directory. Confirm your tax year and current deadline with the official office and your property’s notice.

- Payment deadline
- 2026 Texas property taxes are due upon receipt of the tax statement and generally become delinquent after January 31, 2027 (February 1, 2027); installment and local statutory exceptions may apply.
- Assessment appeal
- May 15, 2026 or the 30th day after the notice of appraised value was delivered, whichever is later; Atascosa CAD's official home page repeats this 2026 protest rule.

April 30, 2026 for most property-tax exemptions and special-appraisal applications. A qualifying residence-homestead owner may late-file up to two years after the taxes become delinquent; age-65-or-older and disabled applicants have additional statutory late-filing rules.
Senior relief
Texas provides residence-homestead exemptions for qualifying owners age 65 or older or disabled, including an additional school-district exemption; qualifying school-tax amounts generally receive a tax-ceiling/freeze. County and other taxing units may provide additional relief. File with the appraisal district.
Valuation limits
A qualifying residence homestead's appraised value is generally capped at the lesser of market value or the prior year's appraised value plus 10% and new improvements. Texas has no general cap for all property; 2026 special-valuation cap rates are 10.00% for agricultural/open-space land and 7.77% for timberland.
