Tax bills & filing dates
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.
- Tax bill mailing
- For the 2026 tax year, Texas Tax Code §31.01 requires the tax bill by October 1, 2026 or as soon thereafter as practicable; the Texas Comptroller says tax bills generally start mailing in October. No county-specific 2026 mailing date was published by the official source reviewed.
- Payment deadline
- 2026 property taxes are due upon receipt and generally must be paid before February 1, 2027 (January 31, 2027 is the usual payment date); if a statutory deadline falls on a weekend, Texas Tax Code §1.06 postpones the act to the next regular business day. The local bill or tax office controls the posted delinquency date.
- Assessment appeal
- May 15, 2026, or the 30th day after the appraisal district mails the 2026 Notice of Appraised Value, whichever is later, under Texas Tax Code §41.44; no different county-specific 2026 deadline was published by the official source reviewed.
Exemptions & appeals
View exemption application (opens in a new tab)Exemption filing
April 30, 2026, generally, for residence homestead, age-65-or-older and disabled-person applications under Texas Tax Code §11.43 and Comptroller Form 50-114; late residence-homestead applications may be filed under §11.431, while annual special-appraisal applications can have different deadlines.
Senior relief
For a qualifying owner age 65 or older, the school district must provide the 2026 additional $60,000 residence-homestead exemption; local taxing units may adopt additional exemptions. The school-tax ceiling generally freezes school taxes at the amount in the first qualifying year, and eligible owners may use the four-installment plan under Texas Tax Code §31.031. The local CAD determines eligibility and administers the filing.
Valuation limits
Texas Tax Code §23.23 generally limits a qualifying residence homestead's annual appraised-value increase to the lesser of market value or prior appraised value plus 10% and new improvements. For tax years 2024–2026, §23.231 temporarily limits qualifying non-residence-homestead real property valued at $5,320,000 or less for 2026 to the lesser of market value or prior value plus 20% and new improvements; agricultural, timber, wildlife and other productivity appraisals are governed separately.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
