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 Castro County Appraisal District.
Relief programs
The filing guidance for this county is: April 30, 2026 for most residence-homestead, age-65-or-older, disabled, agricultural and other annual applications; a residence-homestead application may generally be filed late up to two years after the delinquency date in qualifying cases under Texas Tax Code §11.43. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationA qualifying owner age 65 or older may receive the mandatory $60,000 school-district residence-homestead exemption for 2026, any locally adopted over-65 exemption administered by the CAD, and a school-tax ceiling. The owner may also elect the statutory four-installment plan by timely paying one-fourth by January 31, 2027 and the remaining installments by March 31, May 31 and July 31, subject to Texas Tax Code §§11.13 and 31.031.
Texas Tax Code §23.23 limits a qualifying residence homestead's 2026 appraised-value increase to the lesser of market value or prior appraised value plus 10% and new improvements. Section 23.231 provides a temporary 20% circuit-breaker cap for qualifying non-residence-homestead real property valued at $5,320,000 or less for tax years 2024–2026; special agricultural, timber, wildlife and other productivity appraisals are governed separately.
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: May 15, 2026, or the 30th day after the 2026 Notice of Appraised Value was mailed/delivered, whichever is later; the deadline printed on the notice controls under Texas Tax Code §§41.44 and 1.06. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
