Key Takeaways
Critical Deadline: The deadline to file a property tax protest in Texas is May 15 or 30 days after receiving your appraisal notice.
High Error Rates: Between 30% and 60% of taxable property is overvalued due to mass appraisal mistakes.
Evidence is Key: Success requires documentation, including photos of damage, repair estimates, and comparable sales data.
Informal Resolution: Most protests are resolved through an informal meeting with the appraisal district before proceeding to a formal board hearing.
Long-term Savings: Lowering your valuation today reduces the baseline for future tax increases for up to three years.
To protest property taxes in Texas, file Form 50-132 with your county appraisal district by May 15 (or within 30 days of receiving your appraisal notice), then attend an informal hearing with evidence supporting a lower valuation.
A property tax protest is your legal right to dispute the market value assigned by your local appraisal district—and since your tax bill is calculated from that value, correcting an overassessment directly reduces what you owe.
Property assessors use mass appraisal models to make educated guesses regarding property value, and as a result, mistakes are common.
And since property appraisals directly impact how much you pay in property taxes, appealing an unfair or inaccurate valuation can save you money. Some common reasons Texas property owners file a protest include:
A property's value is higher than the property's actual market value.
The property is appraised at a higher value than comparable properties in the same area.
There are necessary repairs and outdated infrastructure that are not factored into the valuation.
Appraisal district records list inaccurate information regarding lot size or square footage.
An exemption you are entitled to receive was denied.
You didn't receive the required notice of property appraisal.
In Texas, the correct legal term is protest, though you'll often see it called a property tax appeal. Explore assessed and market value insights and the three-year impact protesting can have on your tax liability.
How Much Are You Over Paying?
Step-by-Step Guide to Texas Property Tax Protest
Filing a tax protest can be complex. Use this step-by-step guide on how to protest property taxes in Texas:
Review Your Notice of Appraised Value
Upon receipt of your appraisal notice, look the document over carefully. Take note of errors, such as miscalculated square footage and property age, or inaccuracies in the property's condition description.
Confirm that you have received any exemptions on homesteaded properties you applied for and are qualified for. Calculate your taxes, and compare the estimated property tax listed on the appraisal notice.
Gather Supporting Evidence
It's not enough to simply say that your tax bill is too high. You will need to be able to prove that this assertion is true. Gather evidence that supports your claim, including:
Comparable sales (comps): Recent sale prices of similar nearby properties.
Depreciation photos: Images showing roof damage, foundation cracks, or deferred maintenance.
Repair estimates: Contractor quotes or receipts for necessary repairs.
Inspection reports: Third-party findings that highlight discrepancies with the appraisal.
Independent appraisal: A licensed appraisal reflecting a lower market value.
Record corrections: Documentation proving errors in square footage, lot size, or features.
3. File Your Protest (Form 50-132)
Use the Notice of Protest form (Form 50-132), available on your county appraisal district's website, to file a formal protest. Attach the evidence you've gathered.
Deadline: May 15 or 30 days after your appraisal notice was mailed—whichever is later. Miss it, and you'll have to wait until the following tax year.
4. Attend Your Hearing
After you file the notice of protest, you will receive a date for an informal hearing with a member of the appraisal staff. Depending on your particular county, you may even be given the opportunity to discuss the evidence you submitted.
Most property tax protest cases end with an informal hearing. When the evidence clearly supports a lower appraisal value, the appraised property value is usually adjusted, along with your tax bill.
5. Understand Outcomes and Next Steps
If you aren't satisfied with the informal hearing outcome, you have the option to appeal to the Appraisal Review Board (ARB). The ARB hears arguments from both the property owner and an appraisal district representative. The independent panel examines the evidence presented and returns a decision.
When further appeals are required, you may take the case before the state district court or enter into binding arbitration. If you choose arbitration, be aware that you are agreeing to accept the arbitrator's decision as final and legally enforceable.
For properties valued over $1 million, you can also appeal the ARB's decision to the State Office of Administrative Hearings (SOAH). However, you must file a Notice of Appeal with SOAH within 30 days of receiving the ARB's order.
Tax Protest Timeline Example
Understanding and following the property tax protest timeline is essential for a successful outcome. A property owner who misses the deadline to appeal will have to wait until the following tax year for the next opportunity to file. Here's what to expect:
April 15 (Notice Received): Review your notice of appraised value for errors in square footage, age, or property condition.
May 15 (Protest Deadline): File Form 50-132 with your county appraisal district if you disagree with the valuation.
Early June (Informal Meeting): The appraisal office has 20 days to file an answer after receiving your notice of protest. Meet with an appraiser to present evidence; most cases are resolved at this stage.
Post-Hearing (ARB): If unresolved, attend a formal hearing with the Appraisal Review Board for a final local decision.
