Texas Property Tax Protests: How to File and Understand Unequal Appraisal

O'Connor discusses how to protest your taxes in Texas, why you should file, and understanding unequal appraisal.

HOUSTON, TX, UNITED STATES, April 1, 2026 /EINPresswire.com/ --


With some of the highest property taxes in America, Texans are always searching for a way to reduce their burden. Exemptions are always the first option, and homeowners and businesses both got boosts to their savings in 2025 with overhauls to homestead exemptions and those for business personal property (BPP). However, when exemptions are not enough, Texans have the constitutional right to protest their taxable value.

Property tax appeals are increasingly common across Texas, with counties like Travis and Fort Bend seeing over one-third of properties protested annually. A well-executed protest often results in a reduction or confirms the appraisal district’s (CAD) valuation. O'Connor covers how to file an appeal, why to file, and which factors to consider before proceeding.

The Notice of Appraised Value

Before starting the appeal process, property owners need to know if they should appeal or not. In late March or early April, owners will receive a notice of appraised value from the CAD. It should display basic information about the property, including ownership, exemptions applied, and the value associated with the property. Many notices come with three values, which can be confusing. Market value is what the property would sell for on the open market on January 1 of the tax year. Appraised value is the market figure that has been constrained by laws and regulations, including appraisal caps. Taxable value is the appraised estimate with exemptions subtracted from it. This is the value that tax rates are applied to. The notice will also have the deadline to file an appeal on it, so be sure to keep this document handy.

Issues That Warrant an Appeal

By studying the assessment, owners can find any errors that the CAD has made. First, inspect all of the basic information. If there is an error in exemptions, the size or classification of the property, improvements that do not exist, or if the owner’s name is incorrect, then these are all issues that need to be appealed. While they may seem basic, all of these problems can cost owners a lot of money if they are not addressed. Ownership and exemption issues will typically cost owners the most. These problems are easy to prove and can be appealed without much effort.

The values are where most people focus their attention, and these can be trickier to understand and protest. The appraisal notice should list the values from the current year and the previous one. Compare these values to see if there was a large spike. Many cities and counties in Texas are seeing skyrocketing values, so it is not unusual to see an increase. However, if the increase is excessive or if the owners feel that it does not reflect the realities of their property, then they have grounds for an appeal.

Value and Unequal Appraisal

When it comes to protesting on value, one of the top reasons is unequal appraisal. Texans are protected by law when it comes to how appraisals are applied to homes and businesses. Properties that are in the same location and have similar attributes, like age and size, should be appraised identically, or at least close to it. If two properties that are alike in all ways are assessed differently, then that is unequal appraisal. This is one of the most commonly appealed issues and often yields the best results.

Unequal appraisal is proven by comparing the property to similar ones in the area. When put side-by-side, the disparity can be evident, which should lead to a reduction. This is usually accomplished by gathering property records from the surrounding area, using data from properties that are the same age and size. Since the CAD often does not use the condition of a home or business as part of their calculation, showing that the property has damage, deferred maintenance, or other issues that demonstrate being overassessed compared to the neighbors is also a strong argument to make.

Evidence Needed

While simple appraisal errors like incorrect ownership are easily corrected, disputes based on value can be more difficult. In addition to proving unequal appraisal, excessive or inaccurate valuation can be demonstrated as well. This is achieved by comparing the market value to property sales over the past few years. This can show that the CAD is overestimating the value of a home. Regardless of what grounds owners use, they will always want photographs to demonstrate conditions, documents like repair estimates to show deferred maintenance or damage, and possibly an independent appraisal to give a protest even more credibility.

The Appeal Ladder

There are three types of appeals, running in a prescribed order. First are informal appeals, which are meetings between the owner and the CAD. These can easily fix clerical or other errors and can lead to significant reductions if the owner has evidence. If that fails or gives a settlement lower than expected, the owner can next try formal hearings with the appraisal review board (ARB). This sees the owner and the CAD present their evidence in front of a three-person panel that decides impartially. If this fails, then litigation is a possibility. Each step leads to the other, with each higher rank requiring more time, evidence, and effort.

How to File an Appeal in Texas

Filing an appeal against values is a straightforward process, especially if owners are just targeting an informal settlement. Even if owners are eyeing an eventual trip to litigation, they will still start with the basics. Due to rising taxes and unreliable appraisals, every Texas taxpayer should explore an appeal annually, even if it is simply to verify what the CAD is claiming.

In order to appeal, follow these basic steps:

Review notice of appraisal for errors, including basic mistakes or unrealistic valuations.

File a protest electronically with the CAD. Many major CADs have online portals to handle appeals. Owners can also file by going to their CAD directly or by mailing a letter using Form 50-132.

Gather evidence that backs up the case. This includes photographs, estimates, documentation of deferred maintenance, property sales studies, and comparisons of the property to similar ones in the area.

Attend an informal hearing with the CAD, in hopes of getting a reduction by using the gathered evidence.

Escalate to a formal hearing with the ARB if owners do not get an adequate settlement from the informal hearing.

Get legal representation and pursue litigation against the CAD. This includes binding arbitration and judicial appeals.
