Texas Property Value Estimator

See how a Texas property's appraised value becomes a taxable value, and estimate the property tax that follows — using the homestead exemption rules verified from the Texas Comptroller.

This is an estimate, not an appraisal. The tool does not value your property; it works through Texas’s value chain from a figure you supply. It is not an official assessment, tax bill, or professional valuation.

How the Texas estimate is calculated

The estimator applies Texas’s verified value chain to the value you enter: the figures that convert a market value into the taxable value the rates apply to, using the state’s own assessment ratio, exemption amounts and cap mechanics. The state does not supply rates — rates are local — so the optional tax estimate uses the rate from your own bill. Every rule number is cited below and was verified from the official source listed.

Limitations

• This is not an appraisal, and it is not an automated valuation model: the value you enter is assumed, not estimated by the tool.
• Only the mandatory $140,000 school district homestead exemption is computed. County, city and other local exemptions vary and are not modeled.
• The tax estimate is only as good as the rate you supply. Taxing-unit rates differ, and Texas's § 23.231 circuit breaker for certain non-homestead properties is not modeled.
• The 10% homestead appraisal cap is not simulated; it requires the prior year's appraised value.

Frequently asked questions

Is this a Texas property appraisal?

No. The estimator takes a value you provide and works out what the Texas property tax system does with it — exemptions, taxable value, and an optional tax estimate at the rate you supply. A licensed appraiser or your county appraisal district determines official values.

How does Texas calculate property taxes?

Each taxing unit applies its rate to your property's taxable value — appraised value minus exemptions. Texas has no assessment ratio: the appraised value is the tax base. Rates are set separately by every county, city, school district and special district.

Why can my actual tax bill be different?

The estimator only computes the mandatory school district homestead exemption; your other taxing units may exempt less. Your combined rate figure may also differ from the rate that actually applies to each unit, and values can change through the protest process.

Does the calculator include the 10% homestead cap?

No. The cap (Tax Code § 23.23) limits how fast a homestead's appraised value can rise, and testing it requires two consecutive years' values. That is what the assessment checker does — this estimator answers a different question.
