Protest Your 2026 Williamson County Property Taxes

Williamson County is one of the fastest-growing counties in the United States, with a population exceeding 600,000 residents. Located just north of Austin, the median home value is approximately $410,000, and at an effective tax rate of about 1.68%, the typical homeowner pays roughly $6,890 per year in property taxes.

The Williamson Central Appraisal District (WCAD) appraises all property in the county annually. In 2024, over 85,000 property tax protests were filed - 31% of all parcels, one of the higher protest rates in the state. Of those protests, 54% resulted in a reduced value at the informal level, with 55% success at the ARB.

While Williamson County's success rates are lower than some neighboring counties, the high protest volume shows that homeowners still find value in challenging their assessments - and the potential savings are substantial given the county's high property values. Property values declined 4.7% year-over-year in recent data, one of the sharper corrections in the Austin metro. Major employers like Dell Technologies and Apple anchor the local economy, but residential values have pulled back from pandemic-era peaks.

Whether you own a home in the established neighborhoods of Round Rock, the historic downtown of Georgetown, or the rapidly expanding communities of Leander and Liberty Hill, protesting your WCAD assessment is especially important in a declining market where assessed values may not yet reflect current conditions.
