In Texas, you file a protest with your county's Appraisal Review Board (ARB), present evidence that your home is overvalued, and the ARB issues a ruling.

How property tax appeals work in Williamson County

Every Texas homeowner has a right to protest their assessed value under Texas Property Tax Code §41.41. In Williamson County, protests are handled by the Williamson Central Appraisal District (WCAD). The deadline is May 15, 2026 — or 30 days after your appraisal notice was mailed, whichever is later.

WCAD uses an online protest system with evidence upload. Williamson values cooled with the broader Austin market — 2026 notices often above current realistic sale comps.

The strongest protests include 3-7 comparable sales from the last 12 months in your immediate neighborhood, adjusted for square footage, age, and condition. Round Rock / Georgetown-area assessors typically reduce values when presented with clear, recent comp data.
