An important duty of the Property Assessor's office is providing public information to assist taxpayers with questions regarding property ownership, assessment, and recent property sales.
The Assessor's office handles thousands of requests annually, by phone, mail, or in person, from current or prospective property owners, as well as from the real estate, legal, and banking communities.
The Office Assistance Division is responsible for assisting the general public in obtaining such information.
The Data Management Division is responsible for maintaining all of Williamson County's property assessment / tax records on the State Comptroller's mainframe.
Reappraisal of property for tax purposes is required on a periodic basis to maintain appraisals at market value and to ensure equity of appraisals throughout the jurisdiction.
Williamson County is on a five-year cycle that consists of four years of comprehensive on-site review of every parcel of property in the county, followed by revaluation of all property in the fifth year.
The Verification Division qualifies and disqualifies all farm, commercial and residential sales. Only qualified sales are used for the five year reappraisal program.
For the Assessor, maps are a means to inventory all real property within the jurisdiction. The Assessor is required to maintain an up-to-date set of maps that display all of the parcels in the county, detailing their locations and physical characteristics.
The Cadastral Mapping Division maintains current digital maps of official property lines, public right-of-ways, county annexations and other features, and maintains databases of transfers of properties and alteration of property lines.
In Williamson County, this is accomplished through the use of a CAD-based GIS (Geographic Information System). Master digital maps are updated to reflect new subdivisions, surveys, property splits and the combining of parcels as they occur, and then paper maps are printed and placed in cabinets for reference and public viewing.
This division appraises Greenbelt values of agricultural properties and establishes rollback taxes to be collected by the Trustee.
Greenbelt Property is subject to a roll-back tax once the land ceases to qualify for Greenbelt status. The roll-back tax is the amount of taxes saved in the last three years by the property being on Greenbelt.
