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.
