How to Protest Property Taxes in Texas: Step-by-Step Guide
Learn how to file a Texas property tax protest step by step, from the May 15 deadline and Form 50-132 to your ARB hearing, then lower your tax bill.
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: The National Taxpayers Union Foundation estimates 30% to 60% of taxable property is over-assessed.
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. Since your tax bill is calculated from that value, correcting an overassessment directly reduces what you owe.
Our 2023 to 2025 Texas study found that in 2025, only 32% of residential properties across 17 Texas counties protested while 68% did not, leaving $1.2 billion in potential savings on the table.
Property assessors use mass appraisal models to estimate property value. It's an inexact science, and as a result, mistakes are common.
And since property appraisals directly impact how much you pay in property taxes, annually protesting 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- There are necessary repairs and outdated infrastructure that are not factored into the valuation.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.

How to Protest Property Taxes in Texas in Five Steps
Filing a tax protest can be complex. Use this step-by-step guide on how to protest property taxes in Texas:
1. 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 Texas property taxes, and compare the estimate against the amount listed on your appraisal notice.
2. 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.
If you don't have the time or confidence to do this yourself, use Ownwell, who manages the entire protest process from beginning to end.
3. File Your Protest (Form 50-132)
Use the Notice of Protest form, Form 50-132 from the Texas Comptroller, to file a formal protest with your county appraisal district. Attach the evidence you've gathered.
Deadline: May 15 or 30 days after you receive your appraisal notice, whichever is later. Miss it, and you'll have to wait until the following tax year.
4. Accept an Initial Offer Letter or Attend Your Hearing
After you file the notice of protest, you will likely receive an offer letter for a reduced value. If it's not low enough, you can request an informal hearing with a member of the appraisal staff.
Pro tip: Texas Tax Code §25.195 requires your county to share evidence they used to appraise your value. However, you must request it.
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 take your protest to the Appraisal Review Board (ARB) for a formal hearing. 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.
The burden of proof favors the property owner. Under Texas Tax Code §41.43, the appraisal district generally must support its value by a preponderance of the evidence. Your right to protest is set out in Texas Tax Code §41.41.
If you aren't satisfied, the appeal path moves through these stages in order:
| Stage | What Happens | Key Detail / Deadline |
|---|---|---|
| Accept informal offer | Counties will sometimes send you an offer. | You can accept here if you think it's fair or take your case to an informal hearing. |
| Informal Hearing | You present your evidence to appraisal district staff. | Most cases resolve here; no formal filing needed. |
| Appraisal Review Board (ARB) Formal Hearing | An independent panel hears evidence from both you and the appraisal district. | The panel returns a decision after both sides present. |
| District Court or Binding Arbitration | You escalate the ARB decision to state district court or arbitration. | Arbitration is final and legally binding. |
| State Office of Administrative Hearings (SOAH) | You appeal the ARB decision through a state administrative hearing. | For properties valued over $1 million ; file a Notice of Appeal within 30 days of the ARB order. |
What Your Protest Could Save You
Your tax bill starts with one number: the market value your appraisal district assigns. Lower that value with a successful protest, and your bill drops with it.
Our 2025 Texas research shows that in many counties assessed values keep climbing even when market values stay flat. For instance, Bexar County, median market value held at $275,930 with 0% change from 2024, yet assessed values kept rising, widening the gap and creating strong protest opportunities.
The math is straightforward: assessed value × effective tax rate = annual tax bill. Here's how it plays out on a $400,000 Texas home valued at the Texas median effective property tax rate of 1.48%:
- Assessed value before: $400,000
- Assessed value after a successful protest: $360,000
- Texas median effective tax rate: 1.48%
- Annual tax bill before: $5,920
- Annual tax bill after: $5,328
- Annual savings: $592
That's $592 back in your pocket from a single protest. Ownwell customers save an average of $774 per year through the protest process.
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 protest 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 your Notice of Protest with your county appraisal district, such as the Bexar County appraisal forms portal, if you disagree with the valuation.
- Early June (informal meeting): The appraisal office has 20 days to answer after receiving your notice. Meet with an appraiser to present evidence; most cases resolve here.
- Post-hearing (ARB): If unresolved, attend a formal hearing with the Appraisal Review Board for a final local decision.
Common Texas Protest Mistakes to Avoid
A strong protest is often about sidestepping a few predictable missteps. Steer clear of these when you challenge your valuation:
- Arguing the tax rate: The ARB rules on your property's value, not the rates set by local taxing units, so rate complaints carry no weight.
- Claiming you can't afford the bill: Your ability to pay has no bearing on market value and won't move the outcome.
- Showing up without evidence: Without comparable sales, photos, or repair estimates, you have little to counter the district's number.
- Skipping the informal meeting: Most protests resolve here. You cannot move to a formal appeal with the ARB without an informal meeting first.
- Missing the May 15 deadline: File by May 15 (or 30 days after your notice), or you wait until the next tax year.
