Williamson County vs Travis County Property Taxes: What Austin-Area Homeowners Need to Know

Comparing Williamson County and Travis County property taxes in 2027? Learn how WCAD and TCAD differ, which county has higher tax rates, and how to protest in both.

If you live in the Austin metro, your property tax experience can vary dramatically depending on which side of the county line your home sits on. Williamson County and Travis County share a border that bisects communities like Pflugerville, Cedar Park, and Leander. The two counties have different appraisal districts, different tax rates, and different protest processes. Here is a complete comparison of everything Austin-area homeowners need to know about Williamson County vs Travis County property taxes in 2027.

The Two Appraisal Districts: WCAD vs TCAD

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.

Property Tax Rates: Williamson vs Travis

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.

  • ✓Williamson County: Total effective rates typically range from 1.8% to 2.4% of assessed value depending on city and school district
  • ✓Travis County: Total effective rates typically range from 1.7% to 2.3% depending on city and school district
  • ✓Round Rock ISD (Williamson): Historically has had lower tax rates than Austin ISD (Travis)
  • ✓City of Austin taxes apply to Travis County properties within Austin city limits; unincorporated Williamson County properties avoid city taxes
  • ✓Both counties allow homeowners to protest the assessed value — not the tax rate itself

Assessment Patterns: How WCAD and TCAD Differ

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.

Protest Deadlines: Both Counties Follow the Same Texas Law

Whether you are in Williamson County or Travis County, the Texas Tax Code sets your protest deadline as the later of May 17, 2027 or 30 days from the date your Notice of Appraised Value was mailed.

  • ✓WCAD protest deadline: May 17, 2027 (or 30 days from notice mailing date)
  • ✓TCAD protest deadline: May 17, 2027 (or 30 days from notice mailing date)
  • ✓WCAD address: 625 FM 1460, Georgetown, TX 78626
  • ✓TCAD address: 850 E. Anderson Lane, Austin, TX 78752
  • ✓TaxAppeal prepares ready-to-sign protest kits in both counties

Which County Has More Protest Opportunity in 2027?

Both counties present protest opportunities in 2027. 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.

Frequently Asked Questions

How do I know if my property is in Williamson County or Travis County? ▾
Look up your property on wcad.org or tcad.org by address. Whichever site returns your property record is your county. Properties near the county line in Pflugerville, Cedar Park, and Leander should verify carefully.
Does it matter which county my Austin-area home is in for taxes? ▾
Yes — the county determines your appraisal district, school district assignment, and total tax rate. Williamson County properties not within Austin city limits avoid City of Austin taxes, which can result in lower total rates.
Which has lower property taxes, Williamson County or Travis County? ▾
It depends on the specific location, city, and school district. Williamson County properties in Round Rock ISD or Georgetown ISD often have lower combined rates than Travis County properties in Austin ISD, but this varies by jurisdiction.
Is Cedar Park in Williamson County or Travis County? ▾
Cedar Park straddles both counties. Most of Cedar Park is in Williamson County (WCAD), but some areas fall in Travis County (TCAD). Check your property record to confirm.
Does TaxAppeal USA serve both Williamson and Travis counties? ▾
Yes. TaxAppeal serves all 254 Texas counties including both Williamson County (WCAD) and Travis County (TCAD) at the same flat $89 fee.

TaxAppeal USA is a self-service document-preparation service. We prepare a ready-to-sign appeal kit and mail it to you; you sign it and mail it to the county yourself. 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 file appeals or represent customers before any appraisal district, board of assessors, board of equalization, value adjustment board, or review board. Every appeal, protest and petition is prepared for the property owner, signed by the owner, and mailed by the owner in the owner’s name. In Florida your petition is signed by you as the property owner under section 194.011(3), Florida Statutes, and the county’s Value Adjustment Board filing fee is paid by you directly to the county. TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
