First Time Property Owners

Welcome to Williamson County, Texas! Laws and practices regarding property taxes vary from state to state. Understanding how the Texas property tax system works sooner rather than later may save you time and money.


In Texas, real property, (land and improvements to the land, such as a building or a paved parking lot), is subject to ad valorem property taxes. “Ad valorem” means “according to value”, and taxing entities use your property’s value to calculate property taxes. The market value of the property (land and improvements) in each county is determined by Appraisal Districts such as Williamson Central Appraisal District (WCAD) by using generally accepted mass appraisal methods and techniques. These methods and techniques help us to value large numbers of properties and help to make valuation more equal and uniform.

In Texas, property is required by law to be valued at 100% of market value as of January 1 of the given year. In addition to being used for taxation, the values are also tested for accuracy by the State Comptroller’s Office on a biennial basis. The results of these tests can affect a school district’s funding from the State. Detailed information about WCAD’s appraisal methodologies can be found on the District’s website at


Exemptions can provide reductions in taxes and protection from increasing values or tax rates. Exemption requirements are regulated by state law, but Appraisal Districts are responsible for reviewing exemption applications and administering the exemptions that are approved. The most common exemptions are those for a property owner’s primary residence (general residence homestead, over-65, disabled persons, disabled veterans), and religious and charitable organizations exemptions. Additional exemption information can be found at


Taxpayers have specific rights and remedies available to them. For example, you have the right to receive exemptions or other tax relief for which you qualify and apply timely. You also have the right to voice your opinions at open public meetings about proposed tax rates and to ask questions of the governing body responsible for setting tax rates.


Taxpayers are guaranteed certain remedies under the property tax system. If you believe your property value is too high, or if denied an exemption, you may file a protest during the specified time frame, as indicated on property owner’s annual appraisal notice. Several options exist for protesting property values. You may protest online, by mail, or in person. If you are unable to reach a resolution online or at a meeting with an appraiser, you will be scheduled for a hearing with the Appraisal Review Board (ARB) to resolve the protest. If you are still dissatisfied with the outcome after it has been reviewed by the ARB, other legal options are available.


Exemptions are not automatic. It is the property owner’s responsibility to file an application before the deadline. Please visit our website to expedite your homestead exemption filing and processing time.

If you are a business owner, you are required to report, or render, taxable business personal property to the Appraisal District, unless the combined total is less than $2,500. Please use our online services to file your rendition at

Property owners should advise WCAD if their property is not listed correctly on local tax records and provide the correct name, current address, and property description or attributes. This is especially important to remember in the event of a death, divorce, and other events that may trigger a change in ownership. Updated ownership information may be submitted to and mailing address information can be updated online at

A full explanation of these rights, remedies, and responsibilities is available on the Texas State Comptroller’s website at

Tax Information

Appraisal Districts determine a property’s value, but they do not determine your tax amount. Tax rates are set by local government entities and each county has an assessor-collector, or tax office, to handle assessment and collections. Once the Chief Appraiser certifies the appraisal roll to the taxing jurisdictions, these local government entities then hold public meetings to set the tax rate upon which the amount of property tax you owe is calculated. You may visit for additional information or to see when entity meetings are being held, or to communicate with entity representatives online.

Most taxing jurisdictions are required to publish a notice in a local newspaper regarding proposed tax rates and must allow public discussion prior to adopting tax rates. For more information about Williamson County tax assessments and payments, visit the Tax Assessor Collector’s website at

Educational Outreach

With more than 240,000 parcels and over 100 taxing jurisdictions in Williamson County, the county has been recognized for its rapid growth in the past decade. During that time WCAD has been grouped with other metropolitan Appraisal Districts in the state. The District’s administrative staff is available to meet with civic, neighborhood and professional groups to explain our state-mandated duties and to help the public understand the property tax process and the options available to reduce their property tax burden.

Database of Property Tax Related Information

The Chief Appraiser will create and maintain a property tax database website that is available to the public and searchable by record number, property address or owner name. The Chief Appraiser will continually update the preliminary data and revised data. This website contains information from officers and employees of the taxing units in the CAD, the property’s market value, taxable value, taxing units, and proposed tax rate. It will also list the date, time, and location of the public hearings for the governing bodies at which the tax rate will be adopted. This database allows the property owners to electronically complete and submit a form to a taxing unit on whether the tax rate proposed by the governing body should be adopted. You may visit this website at
