Equal and Uniform: The Protest Argument Most Texas Homeowners Never Hear About
Two arguments, not one
Texas law gives you two separate ways to argue that your property tax appraisal is too high, and they are not the same argument.
The first is the one everyone knows: your home is appraised above what it would actually sell for. That is a market value protest.
The second is less known and often easier to win: your home is appraised higher than comparable homes around it, regardless of what any of them would sell for. That is an unequal appraisal protest — commonly called “equal and uniform.”
The critical difference is what you have to prove. An unequal appraisal protest does not require you to establish what your house is worth. You can own a home appraised at exactly its market value and still win, if similar homes nearby are appraised lower relative to their size.
Both are listed as separate grounds in Tax Code §41.41(a) — subsection (a)(1) covers value, and (a)(2) covers “unequal appraisal of the owner’s property.” You do not have to choose between them.
Where this comes from in the law
The standard for winning is in §41.43(b), and its structure favors you:
A protest on the ground of unequal appraisal of property shall be determined in favor of the protesting party unless the appraisal district establishes that…
The statute then gives the district three ways to defeat the protest. The third is the one most homeowners can use — §41.43(b)(3):
the appraised value of the property is equal to or less than the median appraised value of a reasonable number of comparable properties appropriately adjusted.
Read that carefully. The protest is decided in your favor unless the district proves otherwise. In an ordinary value protest the district already carries the burden by a preponderance of the evidence under §41.43(a); for unequal appraisal, §41.43(b) puts the specific question — is your value at or below the median of comparables — on the district to answer.
Three phrases do the work, and none of them is defined by a number.
“A reasonable number.” The statute sets no minimum. In Harris County Appraisal District v. United Investors Realty Trust, a published 2001 opinion from the Fourteenth Court of Appeals, the property owner’s expert used seven comparable properties, and the court affirmed relief granted on that basis. The opinion records how he chose them: he “determined what would be a reasonable number of comparable properties… based on characteristics which would tend to most influence value, like location, age, and physical characteristics.” What the court credited was a defensible selection method, not a magic count.
“Comparable properties.” Comparability rests on the principle of substitution — a rational buyer will not pay more for a property than the cost of an acceptable substitute. In practice that means similar size, age, condition, location, and use.
“Appropriately adjusted.” Comparables rarely match your home exactly, so differences have to be accounted for. §23.01(f) requires that the selection of comparables and the adjustments applied under §41.43(b)(3) “be based on the application of generally accepted appraisal methods and techniques,” and that adjustments “be based on recognized methods and techniques that are necessary to produce a credible opinion.”
§23.01(h) then says what “generally accepted” means, naming four sources: The Appraisal of Real Estate and the Dictionary of Real Estate Appraisal, both published by the Appraisal Institute; the Uniform Standards of Professional Appraisal Practice, published by The Appraisal Foundation; and publications covering mass appraisal.
Why this argument is often stronger
The evidence comes from the appraisal district’s own records.
In a market value protest you have to prove what your house would sell for. That means sales comparables, possibly a certified appraisal, and an argument about the market that the district’s appraiser is well equipped to dispute.
In an unequal appraisal protest your evidence is the district’s own appraised values for other properties, published in the certified appraisal roll. The appraiser cannot argue those numbers are wrong. The district set them.
The United Investors court made this explicit. Interpreting the parallel district-court provision, it held that the unequal appraisal remedy “dispenses with the requirement of an independent appraisal” and “requires only a comparison of the appraised value of the property at issue with comparable properties appropriately adjusted.” The court reasoned that the legislature added the provision as part of a Taxpayer’s Bill of Rights to make relief easier to obtain: comparing values already on the tax rolls is plainly cheaper than commissioning appraisals of every comparable.
It works in a rising market.
If home values in your area genuinely went up, a market value protest is hard — the district’s number may well be defensible. An unequal appraisal protest is unaffected by that. The question is not whether values rose. It is whether yours rose more than comparable homes’ did.
And where the two principles collide, uniformity wins.
United Investors also addressed what happens when taxing at market value conflicts with taxing equally. The court held:
If a conflict exists between taxation at market value and equal and uniform taxation, equal and uniform taxation must prevail.
That is why an appraisal can be perfectly accurate and still be reduced.
How the comparison works
The most common method normalizes for size by comparing appraised value per square foot, because a 3,000 square foot home is not directly comparable to a 1,500 square foot home without adjustment.
- Identify comparable properties — similar size, age, condition, and neighborhood.
- For each, divide its appraised value by its square footage.
- Find the median of those figures.
- Compare it to your own appraised value per square foot.
- If yours is higher, multiply the median by your square footage. That product is the value your evidence supports.
This is exactly the arithmetic the expert performed in United Investors: seven comparables ranging from $47.99 to $88.63 per square foot, a median of $62.71, against a subject property appraised at $85.13. The court ordered the value reset to the median.
The point to hold onto: you are not arguing that your home is assessed at the average level. You are arguing it is assessed above comparable homes. The median of your comparable set has to fall below your current figure for the argument to do anything.
When each argument is the right one
Equal and uniform tends to be stronger when:
- Your neighborhood has many similar homes, so comparables are easy to find
- Values in your area rose and a market value argument would be hard to sustain
- Your appraised value per square foot is visibly higher than that of similar nearby homes
- You do not want to pay for a certified appraisal
Market value tends to be stronger when:
- Your home has a condition problem the district does not know about — foundation damage, a failed roof, deferred maintenance
- You bought recently, below the appraised value, and have a closing statement
- Your property is unusual, so genuinely comparable properties are scarce
- You have a recent certified appraisal
That last point has a specific statutory reward. Under §41.43(a-1), if your property is valued at $1 million or less and you deliver to the chief appraiser — at least 14 days before the hearing — a copy of an appraisal performed within the previous 180 days by an appraiser certified under Chapter 1103 of the Occupations Code, the district’s burden rises from preponderance to clear and convincing evidence.
There is a second route to that heightened standard, in §41.43(a-3): if your value was lowered in the preceding year, that reduction was not the result of a written agreement between an agent and the district under §1.111(e), and you file supporting information at least 14 days before the hearing, the district again must meet the clear and convincing standard.
Getting the data
Two provisions matter here, and most homeowners use neither.
§41.461 — the district’s evidence. At least 14 days before your hearing, the chief appraiser must inform you that you are entitled, on request, to a copy of the data, schedules, formulas, and all other information the district will introduce at your hearing. There is no charge. If the district intends to defend your value with a comparable set, you can ask for it beforehand rather than seeing it for the first time across the table.
§41.43(c) — what counts as evidence. “For purposes of this section, evidence includes the data, schedules, formulas, or other information used to establish the matter at issue.” The district’s own methodology is evidence in your protest.
Appraised values for other properties are public record and searchable on every appraisal district’s website.
If the ARB does not agree
The same argument survives past the hearing. §42.26(a)(3) directs a district court to grant relief where “the appraised value of the property exceeds the median appraised value of a reasonable number of comparable properties appropriately adjusted” — the same test, in front of a judge.
A note on citations you may encounter: United Investors discusses this provision as §42.26(d), which is what it was numbered when the case was decided in 2001. The text now appears at §42.26(a)(3).
What this page does not tell you
This explains a legal argument. It does not tell you whether to protest, whether to hire anyone, or what your property is worth.
Assembling a defensible comparable set is real work — selecting properties systematically, applying adjustments that hold up under §23.01(f), and presenting the median calculation clearly. Some owners do it themselves from the district’s own data. Some use software that builds the comparison. Some hire a consultant, an attorney, or a CPA.
Those are different paths with different costs, and this site covers them separately.
