What Is a Texas Property Tax Assessment? A Source-Checked Homeowner Guide

A Texas property-tax appraisal is the appraisal district's determination of a property's value for the tax year. It is not the same thing as the tax bill. Taxing units later apply their adopted tax rates, exemptions, and any applicable appraisal limitations to determine taxable value and the resulting bill.

Source review: August 13, 2026. Property-tax rules and account-specific dates can change. The homeowner's current notice and the responsible appraisal district control.

Three values homeowners should keep separate

• Market value: the value the appraisal district assigns under the Texas Property Tax Code's market-value standard.
• Appraised value: the value shown in the appraisal record after any applicable appraisal limitation is considered.
• Taxable value: the value remaining after applicable exemptions and limitations for a particular taxing unit.

The labels and figures on the current Notice of Appraised Value are the best starting point for a specific property. A homeowner should not substitute a generic statewide example for the figures printed on that notice.

How appraisal districts build the record

Texas appraisal districts appraise many properties at once using mass-appraisal methods. They use property characteristics, market information, neighborhood groupings, and appraisal models. The public property record may include facts such as building area, year built, land characteristics, class, and listed improvements.

Because the process depends on recorded characteristics and grouped market evidence, a useful review separates four questions:

1. Does the public property record describe the home accurately?
2. What market evidence did the appraisal district use?
3. Are comparison properties genuinely similar?
4. Are exemptions, classifications, and appraisal limitations reflected correctly?

Protest timing is notice-specific

The Texas Comptroller describes the usual protest deadline as May 15 or 30 days after the appraisal district mails the Notice of Appraised Value, whichever is later. Special circumstances can produce different deadlines. Homeowners should use the date printed on their current notice and confirm the filing path with the responsible appraisal district.

Current homestead-exemption information

The Texas Comptroller currently states that school districts must provide a $140,000 general residence-homestead exemption. Other exemptions and local-option amounts have different eligibility rules. The appraisal district's chief appraiser determines qualification, so homeowners should use the current Comptroller guidance and their appraisal district's application instructions rather than an older dollar figure.

What an evidence review can organize

A homeowner-controlled assessment review can organize the county record, comparable-property information, market evidence, condition documentation, exemption or classification questions, and the local process. Those evidence lanes should remain separately attributed. A public-record fact is not the same as a homeowner-provided correction, and neither is an outcome prediction.
