Comparing Williamson County and Travis County property taxes in 2026? Learn how WCAD and TCAD differ, which county has higher tax rates, and how to protest in both.
Williamson County properties are valued by the Williamson Central Appraisal District (WCAD), headquartered in Georgetown. Travis County properties are valued by the Travis Central Appraisal District (TCAD), headquartered in Austin. These are entirely separate agencies with different staff, different comparable sales databases, and different historical assessment patterns. If your home is near the county line — in Pflugerville, Cedar Park, Leander, or Brushy Creek — it is critical to know which district has jurisdiction over your property. You can confirm by looking up your property record on wcad.org or tcad.org.
Total effective property tax rates in both counties include multiple taxing entities — the county itself, city taxes, school district taxes, and special district levies. The combined rate varies significantly by exact location.
Both WCAD and TCAD use computer-assisted mass appraisal, but their historical assessment patterns differ. TCAD, covering Austin proper and surrounding communities, has historically been aggressive with assessments in high-demand neighborhoods. WCAD, covering rapidly growing communities like Round Rock, Georgetown, Cedar Park, and Leander, faces the challenge of valuing a market that grew explosively and then corrected. The most important factor is whether your specific property is over-assessed relative to its current market value.
Whether you are in Williamson County or Travis County, the Texas Tax Code sets your protest deadline as the later of May 15, 2026 or 30 days from the date your Notice of Appraised Value was mailed.
Both counties present protest opportunities in 2026. Travis County — particularly Austin proper — has seen significant price corrections in certain market segments including condos and urban homes. Williamson County, particularly communities like Leander, Liberty Hill, and newer Georgetown subdivisions, saw the most dramatic appreciation in 2021-2022 and some of the sharpest corrections thereafter as inventory surged.

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.
