Williamson County at a glance · approximate figures, updated monthly
Figures are approximate and refreshed as counties release updated tax rolls.
Williamson County is located just north of Austin and has been one of the fastest-growing counties in the nation for over a decade. With a population exceeding 650,000, the county includes Round Rock, Georgetown (the county seat), Cedar Park, Leander, Liberty Hill, and Hutto. The arrival of major employers like Apple, which is building a massive campus in northwest Austin near the Williamson County border, has further accelerated growth and driven property values upward. Despite this prosperity, tax delinquencies occur, and they create real opportunities for informed investors.
The Williamson County Tax Office is located at 904 S. Main Street in Georgetown. It collects taxes for the county, its cities, school districts (including Round Rock ISD, Georgetown ISD, and Leander ISD), and special districts. When property taxes go unpaid, the county follows Texas Property Tax Code procedures to foreclose and sell the property at public auction.
Tax sales are held on the first Tuesday of each month at the Williamson County Justice Center in Georgetown. The auctions tend to be competitive due to the area's strong property values and investor interest. Properties in Round Rock ISD and Leander ISD school zones are particularly sought after due to the districts' strong reputations.
Williamson County property values have risen sharply, with median home values exceeding $350,000 in most cities and topping $400,000 in areas like Cedar Park and western Round Rock. Georgetown's Sun City retirement community has driven strong demand in the 55+ housing segment. Leander and Liberty Hill continue to see new construction as the Austin metro expands northward.
Tax delinquent properties here tend to be less common than in larger urban counties, but when they appear, they can offer significant value. Look for older properties in east Round Rock and Hutto, commercial properties along I-35 and Highway 183, and undeveloped land parcels in the county's northern and eastern sections.
The Williamson Central Appraisal District (WCAD) provides detailed online property records. Pay special attention to the school district, as it significantly impacts property values. Also check for any pending development plans or zoning changes that could affect the property's future value. The standard Texas redemption rules apply.
