Every Texas property owner has the legal right to challenge their appraised value each year - no lawyer, no agent, no experience required. This guide covers the complete process: deadlines, grounds, filing, hearings, and what to expect at every step.
A property tax protest is a formal challenge to the value your county appraisal district (CAD) has assigned to your property for tax purposes. In Texas, appraisal districts are required to appraise all property at 100% of market value as of January 1 each year. When an appraisal district over-values your property - whether compared to the actual market or compared to how they've valued your neighbors' homes - you have the legal right to protest.
The protest process is governed by the Texas Tax Code, Chapters 41 and 42. It is an administrative proceeding, not a court case. You file a Notice of Protest with your appraisal district, present your evidence at a hearing before the Appraisal Review Board (ARB), and receive a binding decision. The calendar from filing to a final hearing typically spans 4-10 weeks, but the actual work on your end is minimal - usually 10-15 minutes to generate your filing packet, and a brief 15-30 minute hearing if your case isn't settled informally first.
Protesting is not just for large commercial properties. Texas homeowners frequently achieve meaningful reductions. A $25,000 reduction at a 2% combined tax rate saves $500 per year.
The protest deadline in Texas is May 15, or 30 days from the date your Notice of Appraised Value is mailed - whichever date is later. Your notice will print the specific deadline for your property.
Notices are typically mailed in April. If your notice is dated April 20, your deadline is May 20 (30 days from notice). If your notice is dated March 25, your deadline is May 15 (since 30 days would be April 24, which is before May 15).
Texas Tax Code §41.41 enumerates the grounds on which a property owner may protest. The two most practical and commonly successful grounds are:
Your property is appraised at a higher ratio of its market value - or at a higher value per square foot - than comparable properties in your appraisal district. This ground does not require you to prove what your home is "worth" in the market. It only requires showing that the appraisal district has valued similar homes lower than yours on a per-square-foot basis.
Unequal appraisal is often the strongest argument for residential property owners because:
Texas Tax Code §41.43(b) creates a statutory presumption in your favor: if you present a comp analysis showing the median appraised value of comparable properties is lower than your appraised value, the burden shifts to the appraisal district to rebut your evidence.
The appraised value exceeds the market value - what a willing buyer would pay a willing seller in an arm's-length transaction. This ground is most useful when:
You can - and should - assert both grounds simultaneously on your protest form. Selecting both preserves your rights to argue either at the hearing.
Texas Tax Code §41.41 also allows protests for incorrect property owner information, incorrect exemptions, land classification errors, and other issues. These are less common but worth knowing about if your notice contains factual errors.
The protest process has up to four stages, but most homeowners never need to go past stage three. Here is what to expect:
Submit a Notice of Protest (Form 50-132) to your appraisal district before the deadline. You can file online (via your CAD's iFile portal using the account number and PIN on your notice), by certified mail using Form 50-132, or in person at the CAD office. There is no filing fee.
Some CADs will mail or email a settlement offer before you even attend an informal review. If the offered value meets your expectations, you can accept it, sign, and your protest is closed - no hearing needed. You are never obligated to accept; if the offer is insufficient, simply decline and move forward.
Most appraisal districts schedule a brief informal review with a CAD staff appraiser before your formal ARB hearing. Present your comparable property analysis and state your argued value clearly. The appraiser will typically make an offer here as well - accept it if it's reasonable, or decline and proceed to the ARB.
If no settlement is reached informally, your case goes before the Appraisal Review Board (ARB) - an independent panel of local citizens, not district employees. Hearings are typically 15-30 minutes. Request the district's evidence package at least 14 days before; bring printed copies of your evidence. The district presents first, then you; the ARB votes and issues a written order. If unsatisfied, you may appeal to binding arbitration or district court within 60 days.

Missing the deadline forfeits your right to protest for that tax year. File as soon as you receive your notice - online filing with Citizens Tax Protest Project takes less than 15 minutes.
An Appraisal Review Board hearing is a brief, informal administrative proceeding - not a courtroom. It typically lasts 15–30 minutes. A panel of 3 ARB citizens hears the case:
The appraisal district presents its evidence first, then you present yours. Both sides may ask questions of each other. The ARB votes on a final appraised value and issues a written order. You are allowed to cross-examine the district's representative and to object to their evidence.
Before the hearing, always request the district's evidence package (at least 14 days in advance). Bring printed copies of your comp analysis for each ARB member.
The ARB is an independent panel of local citizens - not appraisal district employees - appointed to hear disputes between property owners and the appraisal district. ARB members complete required training in Texas property tax law and are paid a per-diem for each hearing they conduct.
The ARB is structurally separate from the appraisal district. It can overrule the district's appraisers. Its decisions are legally binding on both parties. You can appeal an unfavorable ARB decision to district court or through binding arbitration.
No. Your homestead exemption and your appraised value are entirely separate. Protesting your value has absolutely no effect on your exemption status. You will not lose your homestead exemption by protesting - ever.
In fact, a lower appraised value combined with a homestead exemption means a lower tax bill. If you have not applied for your homestead exemption, visit your CAD's website to apply - the typical deadline is April 30.
Yes - and it is one of the strongest forms of evidence available. Under Texas Tax Code §41.43(b)(3), an arm's-length purchase price creates a statutory presumption that the appraised value exceeds market value. The appraisal district must rebut that presumption.
Attach your Closing Disclosure (or HUD-1 settlement statement) as an exhibit. Your opinion of value should be at or near the purchase price. This works best when the purchase is recent (within the past 12–18 months) and was a standard market transaction - not a foreclosure sale, estate sale, or sale between family members.
Unfortunately, missing the deadline generally means you cannot protest for that tax year. Texas Tax Code §41.44 is firm on this. There are very limited exceptions:
Clerical error correction: If there is a factual error in your property record (wrong square footage, wrong property classification), you can file for a correction at any time under §25.25.
Late filing for late notice: If the CAD never sent your notice or sent it to the wrong address, there may be grounds to argue you did not receive proper notice - but this is contested and uncertain.
The best strategy: file immediately when you receive your notice. Don't wait for a second notice or assume no news is good news.
If you are unsatisfied with the ARB's decision, you have several options:
Binding Arbitration (§41A): A neutral third-party arbitrator reviews the evidence and issues a binding decision. Available for residential and other properties valued under $5 million. Must be requested within 60 days of the ARB order. Filing fee ranges from $450 to $1,550 depending on property value (partially refundable if you prevail).
District Court (§42.01): File a lawsuit in the county district court within 60 days of the ARB order. The court will determine the correct appraised value. This is expensive and primarily used for high-value or complex properties.
State Office of Administrative Hearings (SOAH): An alternative to district court for qualifying property owners. A SOAH administrative law judge decides the case.
