Deadline Calculator
Enter your county and the date your Notice of Appraised Value was mailed to estimate your protest filing deadline.
Important: Always confirm your deadline with your county appraisal district.
This tool provides an educational estimate only. Official deadlines are set by your county CAD — not this website. Texas Tax Code §41.44 governs protest deadlines; your county may have specific rules. Never rely solely on this tool when making filing decisions.
