How Tom Green County Assesses Property

100%of market value

Assessed by: Tom Green County Appraisal District

Assessment cycle: annual

Notices typically mailed: April-May

Tom Green County Appraisal District appraises all property at 100% of market value. Texas law requires properties to be assessed at full market value with no assessment ratio reduction. For example, if your home's market value is $186,700 (the county median), at Texas's 100% assessment ratio your assessed value would be $186,700 before exemptions. At the county's effective rate of 1.11%, this would result in approximately $2,072 in annual taxes before applying any homestead or other exemptions.

The Protest Process

Appeals are heard by the Appraisal Review Board (ARB). After filing your protest, you will first be offered an informal hearing with a Tom Green CAD appraiser to review your evidence and negotiate a settlement. If no agreement is reached, you will proceed to a formal ARB hearing where a panel reviews your case and issues a binding order.

Review your Notice of Appraised Value carefully when it arrives in April or May, noting your property's appraised value and the protest deadline date printed on the notice.

Gather evidence to support your protest including comparable home sales from the past 12 months, photos of property defects or damage, repair estimates, and documentation of any errors in the property description.

File your protest by May 15, 2026 (or 30 days from notice delivery, whichever is later) using the online portal at tomgreencad.com, by mailing Form 50-132, by hand-delivering to the CAD office at 2302 Pulliam Street, or by emailing to protest@tomgreencad.com.

Attend the informal hearing with a Tom Green CAD appraiser where you present your evidence and negotiate a settlement. Many protests are resolved at this stage with an 80% success rate for informal hearings in Tom Green County.

If you disagree with the ARB decision, you may file a further appeal to the State Office of Administrative Hearings (SOAH) for binding arbitration within 60 days of receiving the ARB order.

As a final option, you may file a judicial appeal in state district court within 60 days of receiving the ARB order, though this requires payment of taxes or posting a bond.

How much can I save by protesting my property taxes in Tom Green County?

Property owners in Tom Green County saved over $5.44 million in 2023 through property tax protests, with an average reduction of $2,381 per protested account. Your individual savings depend on how much your property is overvalued and the strength of your evidence.

Since there is no cost to file a protest and no risk of your value increasing, protesting annually is strongly recommended if you believe your property is overvalued.

What evidence do I need for a successful Tom Green County property tax protest?

The most persuasive evidence for a Tom Green County property tax protest includes comparable sales from similar homes in your area that sold within the past 12 months for less than your appraised value. Gather at least three to five comparable properties with similar square footage, age, condition, and location. Other strong evidence includes photos documenting property damage, needed repairs, or poor condition; written repair estimates or contractor bids; and documentation of any errors in the appraisal district's property record such as incorrect square footage, wrong number of bedrooms, or overstated features. You should organize your evidence in a clear, professional format such as a comparison grid showing how your home's value compares to recent sales. The Tom Green CAD is required to provide you with their evidence packet upon request at no cost.

Can I protest my Tom Green County property taxes every year?

Yes, Texas law allows you to protest your property taxes every year in Tom Green County, even if you protested the previous year or recently purchased your home. Many property owners mistakenly believe they can only protest if their value increased significantly, but you have the legal right to challenge your appraised value annually regardless of whether it increased, decreased, or stayed the same. In fact, protesting annually is recommended because market conditions change, new comparable sales become available, and appraisal districts may overvalue properties using mass appraisal computer models. There is no cost to file a protest, and Texas law prohibits the appraisal district from increasing your value solely because you filed a protest. In Tom Green County, about 65% of protests are successful, making annual appeals a smart tax-reduction strategy.

When will I receive my property tax bill in Tom Green County after protesting?

If you file a protest in Tom Green County, your property tax bill will be delayed until your protest is resolved, which typically occurs between August and November depending on your hearing date. Once the Tom Green CAD issues a final order determining your property's appraised value, the appraisal roll is certified to the county tax assessor-collector, who then calculates and mails your tax bill. Your bill will reflect the outcome of your protest and will include the standard January 31 payment deadline. If you receive a settlement or reduction through your protest, you will only pay taxes on the reduced appraised value. Even while your protest is pending, you can make a partial payment based on the undisputed amount to avoid potential penalties, though you should confirm this amount with the appraisal district.
