How to Protest?

You have a right to lower property taxes! State law prescribes a procedure for protesting the assessed value of your property, upon which you are taxed by multiple taxing jurisdictions. The process is sometimes laborious and can be painstaking. But it is possible to achieve results if you can present evidence to support your case.

You may represent yourself, or you may engage an agent to represent you by signing an Appointment of Agent form. Any agent who presents an appeal on your behalf must be a Licensed Tax Consultant in the State of Texas or possess another related real estate license.
