Complete guide to protesting your Williamson County property taxes in 2026. Beat WCAD with comparable sales evidence. Covers Round Rock, Cedar Park, Georgetown, Leander, and Liberty Hill.
The Williamson Central Appraisal District uses computer-assisted mass appraisal to value all real property in Williamson County as of January 1st each year. Williamson County's extraordinary growth creates particular valuation challenges. When Austin-area prices surged 40-50% between 2020 and 2022, WCAD assessments followed aggressively. When the market corrected in 2023-2024, WCAD was slow to follow. The result: many Williamson County homeowners are still assessed at peak-market values that significantly exceed what their homes would sell for today.
The Williamson Central Appraisal District mails Notices of Appraised Value in April. Your protest deadline is the later of May 15, 2026, or 30 days from the mailing date on your notice.
The Austin metro was one of the hottest real estate markets in the country from 2020 to 2022. Median home prices in Round Rock, Cedar Park, and Georgetown jumped 40-50% in two years. Since then, rising interest rates have significantly cooled demand. Active inventory in communities like Leander and Liberty Hill has climbed, and WCAD's 2026 assessments still lag the real-time market in many neighborhoods.
The most effective WCAD protests combine comparable sales evidence with property-specific documentation. Hyper-local comps from your immediate subdivision carry the most weight.
The Williamson Central Appraisal District covers all of Williamson County including Round Rock, Georgetown, Cedar Park, Leander, Liberty Hill, Taylor, Hutto, Pflugerville (Williamson County portions), Brushy Creek, Jarrell, and all unincorporated areas.

TaxAppeal USA is a self-service document-preparation and mail filing service. In every state we serve, including Florida, we are not property tax consultants, agents, or representatives, we do not provide tax or legal advice, and we do not represent customers before any appraisal district, board of equalization, value adjustment board, or review board. Every protest and petition is prepared for the property owner, signed by the owner, and filed in the owner’s name. In Florida we also pay your county’s Value Adjustment Board filing fee on your behalf and mail your petition to the Clerk of the Value Adjustment Board. Your petition is signed by you as the property owner under section 194.011(3), Florida Statutes. TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
