How to Protest Your Property Taxes in Texas

How to protest your property taxes in Texas

To protest your property taxes in Texas, you file a written Notice of Protest with your county appraisal district (CAD) by the deadline printed on your Notice of Appraised Value, then present evidence that your property's assessed market value is too high or unequal — first in an informal review with an appraiser, and if unresolved, in a formal hearing before the Appraisal Review Board (ARB).

Texas has no state property tax; your taxes are based on the value your county appraisal district assigns to your property each year. The protest process is your legal right as a property owner to challenge that value before it becomes final and before tax bills are calculated. This guide walks through the process using Texas's own terminology, but you should always confirm the exact dates and requirements against the notice you receive.

Understand the Texas terms first

Knowing the vocabulary makes the process far easier to navigate.

Key players and documents

• County Appraisal District (CAD): The local office that determines the value of every property in the county (for example, the Harris, Travis, or Dallas Central Appraisal District). You protest to the CAD, not to the taxing units.
• Notice of Appraised Value: The document the CAD mails when your value rises or in other situations defined by law. It shows your proposed value and the protest deadline.
• Notice of Protest (Form 50-132): The state form used to file your protest. Many CADs also accept an online protest or a signed letter with the same information.
• Appraisal Review Board (ARB): An independent panel of local citizens that hears protests the CAD cannot resolve informally and issues a binding decision.
• Taxing units: The school districts, cities, counties, and special districts that set tax rates and send bills based on the CAD's final values.

Grounds for a Texas protest

Two of the most common grounds are:

• Market value is too high: The CAD's value exceeds what your property would sell for on the open market.
• Unequal appraisal: Your property is appraised higher than comparable properties, even if the raw market value seems defensible.

You can list more than one ground on your Notice of Protest to preserve your options.

Step-by-step: how to protest

1. Read your Notice of Appraised Value carefully. Note the proposed value, the stated protest deadline, and any instructions specific to your CAD.
2. Decide your grounds. Check both "market value" and "unequal appraisal" if either might apply — you can narrow later.
3. File your Notice of Protest on time. Submit Form 50-132, the CAD's online portal, or a signed written protest before the deadline on your notice. Filing late can forfeit your right to a hearing.
4. Request the CAD's evidence. Under Texas law you can ask the appraisal district for the information it plans to use, so you can see how your value was determined.
5. Gather your own evidence. Recent comparable sales, an independent appraisal, photos of damage or defects, repair estimates, and equity comparisons to similar nearby properties all help.
6. Attend the informal review. Meet with a CAD appraiser to try to settle on a value without a formal hearing. Many protests are resolved here.
7. Present at the ARB formal hearing if needed. If you don't reach agreement, present your case to the Appraisal Review Board. Be concise, organized, and factual.
8. Review the ARB's written order. The board issues a decision. If you disagree, Texas law provides further options, such as binding arbitration, an appeal to district court, or (for some cases) the State Office of Administrative Hearings, depending on eligibility.

Evidence checklist

Bring organized copies for yourself and, where required, for the board:

• [ ] Your Notice of Appraised Value
• [ ] Filed Notice of Protest (confirmation or copy)
• [ ] Comparable recent sales near your property
• [ ] Comparable assessments of similar properties (for unequal-appraisal claims)
• [ ] Independent fee appraisal or closing statement, if available
• [ ] Photos of condition issues, deferred maintenance, or damage
• [ ] Contractor repair estimates
• [ ] Any factual errors on the CAD's property record (wrong square footage, bedroom count, lot size)

Tips for a stronger protest

• Verify the property record. Errors in the CAD's data (square footage, condition, or features) are common and often the easiest wins.
• Focus on evidence, not emotion. Boards respond to comparable sales and documented condition problems, not to how the tax bill feels.
• Confirm your homestead and other exemptions are applied correctly, since exemptions affect taxable value separately from the appraised value.
• Keep copies of everything you submit and every deadline, and get confirmation that your protest was received.

Confirm your dates and rules

Protest deadlines, forms, and hearing procedures can vary by county and can change year to year. The most reliable source for your situation is the Notice of Appraised Value from your own county appraisal district and that CAD's website. When in doubt, contact your CAD directly and confirm the deadline before you rely on it.
