Frequently Asked Questions (FAQ’s)

  • How do I protest?
    • The Notice of Protest form is recommended; however, a protest is sufficient if it is in writing and identifies the property subject to protest, the protesting owner name(s), and reason(s) for protest. To preserve all rights during the hearing, an owner should check all protest reasons that apply and make additional written statements to clarify the protest.
  • Can I file a protest through email or fax?
    • No. The ARB will not accept protests submitted by fax or email. Protests to the ARB must be filed by mail, in person, drop-box (available 24/7) or, if eligible, an owner may file their protest through the appraisal district’s Online Appeals eFile site. If your appraisal notice includes a secure PIN to eFile, we strongly encourage you to use the eFile site to file your protest.

  • Are hearings held at night or on weekends?
    • The ARB must provide hearing times for protests in the evening or on a Saturday. You should contact the appraisal district to see when these hearing times are available.
  • What are some helpful hints when protesting to the ARB?
    • Check the appraisal to make sure the property description and measurements of your property are correct.
    • Check the appraisal to see if it accounts for hidden defects – for example, a cracked foundation or inadequate plumbing. Evidence of a hidden defect could be a photograph, or a statement from a builder or independent appraiser.
    • Research appraisal records on similar properties in the area to learn if similar properties are treated equally.
    • Consider using an independent appraisal by a real estate appraiser. Insurance records are often helpful.
    • Use sales of properties that are similar to the subject property in size, age, location, and type of construction.
    • Use sales that occurred closest to January 1 of the taxing year.
    • Obtain documents or sworn statements from the person providing the sales information.
    • Ask to inspect and obtain a copy of the data, schedules, formulas, and any other information that the appraisal district plans to introduce at the hearing. The appraisal district must make this information available during the 14 days before the protest hearing.
    • Be on time and prepared for your hearing.
    • Stick to the facts of your presentation. The ARB has no control over the appraisal district’s operations or budget, tax rates for local taxing units, inflation, or local politics; addressing these topics in your presentation wastes time and will not help your case.
    • Present a simple and well-organized protest. Stress key facts and figures. Photographs and other documents are useful evidence.
    • Recognize that the ARB acts as an independent judge. The ARB listens to both you and the appraisal district before making a decision. It is not a case of you against the ARB.
