6 Texas Property Tax Myths That Can Cost Owners Money

The size of the year-over-year increase is not the only question. An owner can review whether the current value reflects the property's January 1 market value, whether the appraisal is equal and uniform, whether property characteristics are correct, and whether exemptions or appraisal limitations were applied properly.

For a high-value property, even a relatively small percentage difference can have a meaningful tax effect. For a lower-value property, the expected savings may be smaller. Evaluate the dollars at stake rather than relying on the percentage change alone.

Texas appraisal districts may use mass-appraisal standards, but Texas law also requires generally accepted appraisal methods and techniques and consideration of property-specific evidence. Depending on the property, appraisal districts may use sales-comparison, income, cost, or other appropriate appraisal methods.

That means the right question is not whether a computer model was used. The question is whether the final appraisal reflects the property's individual characteristics and is supported by credible market, income, cost, or equal-and-uniform evidence.

Texas taxpayers have the right to protest their property's value and other appraisal matters. A year-over-year increase is not the only possible protest issue.

Depending on the facts, an owner may challenge market value, unequal appraisal, incorrect property records, exemption treatment, special-appraisal qualification, circuit-breaker treatment, or another appraisal-district action concerning the property.

Market conditions such as financing costs or changing demand can matter only to the extent they help explain the property's value as of the relevant appraisal date. Personal financial hardship by itself is not a valuation argument.

An ARB protest determination is binding for the tax year at issue; Texas property is appraised again in later years. A reduction this year therefore does not guarantee the same value or the same dollar savings next year.

However, a prior reduction can still matter. Under Tax Code §23.01(e), when a property's appraised value was lowered through the protest or appeal process, a later increase in the next year in which the property is appraised can trigger a higher clear-and-convincing evidentiary burden for the chief appraiser under the statute. That is different from saying the prior value is permanently frozen.

A Texas property owner can file and present a protest without hiring an attorney or property tax consultant. The Comptroller provides Form 50-132, Property Owner's Notice of Protest, and an owner may also appoint an authorized agent if desired.

Whether professional representation makes economic sense depends on the complexity of the property, amount in dispute, evidence required, owner's available time, likely post-ARB issues, and the professional's fee structure. Fee arrangements vary by firm, so review the engagement terms rather than assuming every service is contingency-based or “risk-free.”

Neither a recent purchase nor new construction automatically eliminates the owner's protest rights. Texas generally appraises taxable property at market value as of January 1 and requires the appraisal to consider the property's individual characteristics.

A recent arm's-length purchase price close to the appraisal date can be important evidence, but it is not necessarily the only evidence. For construction, the relevant facts include what actually existed and the applicable appraisal law as of the appraisal date. The older version of this article was too broad in saying new construction is commonly appraised at projected stabilized value.
