Generate a Texas property tax assessment appeal letter. Challenge your appraisal district valuation under Tax Code Ch. 41 before the May 15 deadline.
Generate My Letter — $39If you own property in Texas, your county appraisal district (CAD) sets the taxable value of your home or business each year. When that value is too high, you pay too much in property tax. Texas law gives every property owner the right to formally protest the assessment before the Appraisal Review Board (ARB). A well-drafted protest and appeal letter can resolve the dispute informally, secure a hearing date, and create the paper trail needed for further appeal to district court or binding arbitration. Because Texas has no state income tax, property taxes are unusually high, and the appeal process is one of the few ways to lower your annual tax bill. Acting before the May 15 deadline is critical—miss it, and you generally lose the right to challenge that year's value.
Texas property tax appeals are governed primarily by Chapters 41 and 42 of the Texas Tax Code. Under § 41.41, a property owner may protest several types of determinations made by the chief appraiser or appraisal district, including: (1) the appraised or market value of the property, (2) unequal appraisal compared to similar properties, (3) inclusion of the property on the appraisal roll, (4) denial of an exemption such as homestead, agricultural, or over-65, (5) wrongful denial of special use valuation, and (6) any other action that adversely affects the owner.
The appraisal district must send a Notice of Appraised Value (often called a 'NOV') when value increases or under other conditions specified in § 25.19. Once you receive the notice, § 41.44 requires you to file a written Notice of Protest by May 15 or within 30 days after the notice was delivered, whichever is later. The protest must identify the property and indicate that you are dissatisfied with a determination.
After filing, the ARB schedules a hearing. You are entitled under § 41.461 to request, at least 14 days before the hearing, copies of the evidence the appraisal district plans to use, along with the comparable sales and equity data supporting the value. If the ARB rules against you, § 42.01 allows appeal to district court within 60 days of the order, or you may pursue binding arbitration under Chapter 41A for properties valued at $5 million or less, or a State Office of Administrative Hearings appeal for certain commercial properties. Homestead owners benefit from the 10% appraisal cap under § 23.23, and successful taxpayers may recover attorney's fees under § 42.29.
A Texas property tax appeal letter serves two purposes: it acts as the formal Notice of Protest required by § 41.44, and it puts the appraisal district on notice of the specific factual and legal grounds for your challenge. While the Comptroller's Form 50-132 is the standard protest form, a detailed cover letter strengthens your position and often prompts the appraisal district to settle informally before the ARB hearing.
An effective letter should: (1) identify the property by account number and legal description, (2) state the protest grounds—usually 'over market value' and 'unequal appraisal' should both be checked to preserve all rights, (3) propose your opinion of value supported by recent comparable sales, a recent appraisal, repair estimates, or photos of property condition, (4) request the appraisal district's evidence packet under § 41.461, and (5) demand an informal conference with an appraiser before the formal hearing.
Most Texas counties—including Harris, Dallas, Travis, Bexar, and Tarrant—offer informal settlement conferences where roughly half of protests are resolved without an ARB hearing. A clear, evidence-based letter signals that you are organized and prepared to escalate, which encourages the appraiser to make a reasonable adjustment. If the appraisal district ignores or rejects your letter, the same document supports your formal ARB hearing and any subsequent district court appeal under Chapter 42.
File the Notice of Protest with the Appraisal Review Board through the appraisal district's office, online portal, or by certified mail postmarked by the deadline. There is no filing fee at the ARB level. If you appeal an adverse ARB order to district court under § 42.21, you must file within 60 days and pay the standard district court filing fee (typically $300–$400). For binding arbitration under Chapter 41A, the deposit ranges from $450 to $1,550 depending on property value and is refunded if you substantially prevail. Texas small claims (justice court) jurisdiction caps at $20,000 but does not handle ad valorem tax appeals—those must go to the ARB, district court, arbitration, or SOAH. You must continue paying the undisputed portion of taxes during the appeal to preserve your rights under § 42.08.
