Property taxes are the primary source of government revenue in Texas. These are local taxes based on the property's value that helps pay for public schools, city streets, county roads, police, fire protection, and many other services.
The Williamson County Tax Assessor Collector's Office currently handles the following:
- Collection of property taxes for Williamson County and other taxing jurisdictions
- Occupational License Tax (Georgetown office only)
- Issuing of Tax Certificates (Georgetown office only)
- Collection of Vehicle Inventory Tax (Georgetown office only)
Please note that the Williamson County Tax Collector only collects property tax for the County and other jurisdictions. We are not responsible for setting tax rates or determining property values.
The governing bodies of the applicable taxing jurisdictions for your property set your tax rates. You are encouraged to express your views at your taxing jurisdiction's tax rate public hearings. These hearings are typically held in August and September. Information about dates and times is posted in newspapers and websites before the hearings. You can find information about tax rates for jurisdictions throughout the County by visiting the Tax Rates page.
How Your Tax Can Be Calculated
