What Evidence Helps in a Texas Property Tax Protest

A strong Texas property tax protest is built on documented, property-specific evidence, not a strong opinion about what your property is worth. Every year, homeowners and business owners walk into appraisal review board hearings certain their assessment is too high, and walk out with the same number they started with. The difference often comes down to what evidence is actually in the file, and how it is presented.

Why “It Feels Too High” Rarely Moves the Needle

Appraisal districts hear the same argument constantly: the taxes went up too much, the neighborhood does not support that value, a friend's house is worth less. None of that is wrong to feel. It is just not evidence.

At an ARB hearing, both the property owner and the appraisal district may present evidence and argument regarding the property's value. In most value protests, the appraisal district has the burden of establishing the property's value by a preponderance of the evidence. In certain circumstances, Texas law imposes a higher clear-and-convincing evidence standard. Strong, property-specific documentation from the owner can support that challenge. A frustrated opinion, without more, generally does not.

Evidence That Can Strengthen a Property Tax Protest

Comparable Sales Data

Recent sales of reasonably comparable properties can be important evidence in a market-value protest. The comparables should be genuinely similar in size, age, condition, and location, not just nearby. This is different from an equal-and-uniform protest, which compares your appraised value to similar properties' appraised values rather than sale prices. Texas property owners have a right to both types of protest, and the right analysis depends on the situation.

Photos of Condition Issues

Foundation cracks, roof damage, outdated systems, or deferred maintenance can all affect what a property is worth. The Texas Comptroller's own guidance lists property photographs among the information owners should consider bringing to a hearing. Photos are often most useful when paired with a repair estimate or other documentation showing how the condition affects value.

Repair and Contractor Estimates

A written estimate from a qualified contractor or repair professional can turn “this needs work” into a specific dollar figure the appraisal district can weigh.

Income and Expense Documentation (Certain Commercial Properties)

For income-producing commercial real estate, rent rolls, occupancy information, lease terms, income statements, and operating expenses can be relevant evidence when an income approach is the appropriate valuation method for that property.

Documentation for Business Personal Property

Business personal property, such as equipment, furniture, fixtures, and inventory, is often valued differently than commercial real estate. Useful documentation can include asset lists, acquisition dates, original cost, depreciation schedules, and information about the condition or obsolescence of specific assets. The right records depend on what is being protested.

Independent Appraisals

A recent, independent appraisal from a licensed appraiser can be useful evidence, particularly for properties where comparables are harder to find.

What Does Not Hold Up Well

Unsupported claims, secondhand stories about a neighbor's value, or general statements about the market being “crazy right now” rarely change an outcome on their own. The Texas Comptroller's guidance is direct on this point: property owners should come prepared with relevant information, not just an argument that the appraisal district is wrong. Unsupported assertions tend to carry less persuasive weight than property-specific evidence, regardless of how legitimate the underlying concern may be.

Building a Package That Holds Up

Evidence does not help much if it is disorganized or arrives at the hearing incomplete. A strong package is assembled early, tied directly to the property's specific issues, and structured the way the appraisal district and ARB actually review cases. This is where experienced representation can make a real difference, not just knowing what evidence exists, but knowing how to organize and present it.

A home protest and a commercial protest call for different evidence, but the same rule applies either way: the appraisal district will not build your case for you.
