🔴 2026 Protest Deadline: May 15, 2026 — or 30 days after your Notice of Appraised Value is mailed, whichever is later. Miss this date and you waive your right to protest.
Williamson County (Wilco) is one of the fastest-growing counties in the United States, anchored by Georgetown, Round Rock, Cedar Park, and Leander. The tech sector boom, Austin metro spillover, and major corporate relocations have driven population from 609,000 in 2020 to more than 727,000 by 2024. Appraisals surged during the 2020–2022 run-up and in many cases have not corrected proportionally to market normalization since.
In 2024, 54% of Williamson County protests resolved through the informal process received a value reduction, and 55% of written ARB determinations lowered the appraised value (Texas Comptroller, 2024 Appraisal District Operations Survey). The Williamson Central Appraisal District processes a high volume of protests, and the informal settlement process is active and productive. With an average tax bill approaching $4,000, even a 5% reduction saves real money. File before May 15.
