The Complete Guide to Protesting Your Property Taxes in Texas
Start by checking the property details and assessed values in your county record. Comparable properties, condition photos, and supporting documents can help you understand whether the assessment deserves a closer look.
You can challenge an appraisal district decision through the property tax protest process. A reduction depends on the evidence and the decision in your case. See the Texas Comptroller's protest guidance.
Understanding Texas Property Taxes
Your appraisal record and tax bill answer different questions. Review your home's recorded characteristics, the assessment year, and the values shown before comparing it with neighboring homes.
Home-Sage's savings calculator explores scenarios using an estimated tax rate. Treat its result as an estimate; review your own tax bill before relying on it.
Key filing deadlines
Check your notice for the applicable deadline and exceptions. Texas Comptroller filing guidance.
May 15 (or 30 days after your Notice of Appraised Value is mailed, whichever is later) — this is the deadline to file your property tax protest with your county appraisal district.
- January 1 — Appraisal date. Your property is valued as of this date.
- April 1 - May 1 — Most counties mail Notices of Appraised Value.
- May 15 — Standard protest filing deadline.
- May - September — Appraisal Review Board (ARB) hearings are scheduled.
Grounds for Protest
Texas law (Section 41.41 of the Texas Property Tax Code) allows you to protest on several grounds:
- Market value is too high — The most common basis. Your appraised value exceeds fair market value.
- Unequal appraisal — Your property is valued higher than comparable properties in your area.
- Incorrect property data — Wrong square footage, lot size, year built, or other factual errors in the appraisal record.
- Failure to send notice — You didn't receive your Notice of Appraised Value.
- Exemption denied — You were denied a homestead or other exemption you're entitled to.
What Evidence Do You Need?
For a Market Value Protest
- Recent comparable sales (within the last 6-12 months) of similar properties in your area
- Photos showing property condition issues (deferred maintenance, foundation cracks, dated interiors)
- Professional appraisal if available
- Repair estimates for any needed work
For an Unequal Appraisal Protest
- Comparable properties with lower appraised values per square foot
- Statistical analysis showing your property is valued above the neighborhood median
- Properties with similar characteristics (size, age, lot, features) that are assessed lower
- Percentile ranking showing your property is in the upper range of neighborhood values
This is exactly what Home-Sage automates — our AI pulls comparable properties directly from your county's CAD data, calculates price-per-square-foot rankings, and generates charts and evidence tables ready for your protest filing.

The Protest Process: Step by Step
1. File Your Protest
You can file online through your county's CAD website, by mail, or in person. You'll need your property ID (found on your Notice of Appraised Value) and you'll select your grounds for protest.
2. Informal Hearing
Most counties offer an informal hearing first, where you meet with an appraiser to discuss your case. Many protests are resolved at this stage. Bring your evidence — comparable properties, photos, and data supporting your case.
3. Appraisal Review Board (ARB) Hearing
If the informal hearing doesn't resolve your protest, you'll attend a formal ARB hearing. This is a panel of citizens who will review your evidence and the appraisal district's position, then make a binding determination.
4. Further Appeals
Further appeal options have eligibility rules and deadlines. Regular binding arbitration may cover a residence homestead regardless of value, or other property valued at $5 million or less. Consult the Comptroller's appeal guidance before choosing a route.
Tips for a Successful Protest
- Plan ahead — check the deadline on your notice and allow time to gather your records.
- Match your argument to your evidence — distinguish assessment comparisons from evidence of market value.
- Use data, not emotion — ARB panels respond to comparable property data, price-per-square-foot analysis, and objective evidence.
- Check your property details — verify your square footage, lot size, year built, and number of rooms are correct in the CAD records. Errors are more common than you'd think.
- Protest every year — even if you were denied last year, property values and comparables change annually.
