Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Dimmit Central Appraisal District.
Relief programs
The filing guidance for this county is: Before May 1, 2026 (generally April 30, 2026); file the residence-homestead application with the county appraisal district. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationTexas Comptroller guidance: a qualifying owner age 65 or older or a qualifying disabled person receives the additional $60,000 school-district residence-homestead exemption in 2026; local taxing units may adopt additional exemptions of at least $3,000. The school-tax ceiling generally freezes at the amount in the first qualifying year, and eligible owners may request four-installment payment treatment from the tax collector. Local CAD eligibility and documentation rules apply.
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 2026, §23.231 temporarily limits qualifying non-residence-homestead real property valued at $5,320,000 or less to prior appraised value plus 20% and new improvements; agricultural, timber, wildlife and other productivity appraisals are governed separately. The Texas Comptroller's 2026 special-valuation cap rates are 10.00% for agricultural/open-space land and 7.77% for timberland.
Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: June 8, 2026, or 30 days after the 2026 appraisal notice was mailed, whichever is later (Dimmit CAD 2026 notice). If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
