Atascosa County Appraisal District

If you believe the Atascosa County Appraisal District has overvalued your property, you have the right to formally protest that value. Understanding the process before the deadline arrives puts you in a stronger position to succeed.

Know Your Deadline

The protest deadline in Atascosa County is May 15, or 30 days after the date your appraisal notice was mailed — whichever is later. Missing this window eliminates your right to protest for that tax year, so mark the date as soon as your notice arrives.

File a Notice of Protest

Your protest begins with filing a Notice of Protest (Form 50-132) with the Atascosa County Appraisal District. The district is led by Chief Appraiser Brandi Royal. You can reach the office by phone at 830-569-8326 or visit the district's website at http://www.atascosacad.com/ to download forms and review current procedures. As of the information available, the district does not offer an online filing portal, so protests must be submitted by mail or in person.

Gather Your Evidence

Before your hearing, build a case around comparable sales. Look for recent sales of similar properties in your area that sold for less than your assessed value. Photographs documenting condition issues, a recent independent appraisal, or repair estimates for structural problems can all strengthen your argument. The burden is on you to show the district's value is incorrect.

The Informal and Formal Hearing Process

Most protests in Texas begin with an informal meeting between the property owner and an appraisal district staff appraiser. Many cases are resolved at this stage without proceeding further. If you cannot reach an agreement informally, your case moves to a formal hearing before the Appraisal Review Board (ARB) — an independent panel that listens to both sides and issues a binding determination.

After the ARB Decision

If you disagree with the ARB's ruling, you may pursue further appeal through binding arbitration, the State Office of Administrative Hearings, or district court, depending on your property type and value. Each option has its own filing requirements and deadlines, so act promptly after receiving the ARB order.

1. What is the protest deadline for Atascosa County property taxes?

The deadline to file a protest with the Atascosa County Appraisal District is May 15, or 30 days after the date printed on your appraisal notice — whichever date falls later. If your notice arrives late in the season, the 30-day window may give you more time than the fixed May 15 date. Either way, do not delay once your notice is in hand.

2. How do I file a property tax protest in Atascosa County?

Because the Atascosa County Appraisal District does not currently offer an online filing portal, you must submit your Notice of Protest by mail or deliver it in person to the district office. Contact the district at 830-569-8326 or visit http://www.atascosacad.com/ to confirm current submission procedures and obtain the required forms. Make sure your submission is postmarked or received before the applicable deadline.

3. What homestead exemption is available in Atascosa County?

Atascosa County offers a General Residence Homestead exemption of $140,000 or 20% — whichever is greater — applied against your property's assessed value for school district taxation purposes. Additionally, homeowners who are 65 or older, or who qualify as disabled persons, are eligible for an additional $200,000 exemption. These exemptions can meaningfully reduce your taxable value, so it is worth confirming that your exemptions are properly applied before your next tax bill arrives.

4. Are there property tax benefits for veterans in Atascosa County?

Yes. Disabled veterans with a service-connected disability rating between 10% and 100% may qualify for a $5,000 exemption on their property's assessed value. The specific exemption amount can increase based on the disability rating percentage under state law. Veterans should contact the Atascosa County Appraisal District at 830-569-8326 to verify eligibility requirements and submit the appropriate documentation to claim this benefit.

Submit Early and Keep Records

Since the Atascosa County Appraisal District does not offer an online filing portal, you must file your protest by mail or in person. If mailing, use certified mail with return receipt so you have documented proof of timely submission. Keep a copy of every document you send.

Call the District Before You File

Procedures can change between tax years. Before submitting anything, call the Atascosa County Appraisal District at 830-569-8326 or check http://www.atascosacad.com/ to confirm the current preferred method for receiving protests and whether any updated forms are required. Chief Appraiser Brandi Royal's office can direct you to the right forms and answer basic procedural questions.

Build a Comparable Sales File

Atascosa County includes a mix of rural residential properties, agricultural land, and properties near the San Antonio metro corridor. Values in this region can shift significantly based on proximity to growth areas. Pull recent sales data for properties comparable to yours — similar size, age, condition, and location — and document any differences that justify a lower value for your property.

Verify Your Exemptions First

Before investing time in a protest, confirm that all exemptions you qualify for are already applied to your account. If your homestead, over-65, or disabled veteran exemption is missing, correcting that error alone may reduce your tax burden without requiring a formal hearing.

Prepare for the Informal Meeting

Most Atascosa County protests are resolved during the informal review stage. Arrive organized, be specific about the value you believe is correct, and bring printed copies of your supporting evidence. A clear, fact-based presentation — without emotional arguments — is more persuasive to district staff and the Appraisal Review Board.
