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.
Property owners in Texas have the right to protest property taxes if they disagree with the assessed value. A property tax protest is when you dispute the market value of a property as assigned by a local tax authority. Since property taxes are based on a property's current market value, the tax bill will be higher if your property has been overvalued.
Anywhere between 30% and 60% of taxable property is overvalued. 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There are necessary repairs and outdated infrastructure that are not factored into the valuation.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.
Although the term property tax appeal is often used interchangeably to describe a property tax protest, protest is the correct legal term in Texas. This state-specific guide provides a unified look at how counties across the state approach the protest process. Find unique assessed and market value insights into Texas's property tax trends, the three-year impact that protesting can have on tax liability, and survey results from Texas homeowners who went through the protesting 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 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.
Comparing The Four Major Counties in Texas
Although it can result in significant savings, only 22% of Americans protest their property taxes, and this inaction is costing them. Rising median home values and tax liability in four of Texas' major counties are a major impact of the increases in housing costs are having on tax bills in the Lone Star State, as well as across the country.
A successful property tax protest offers savings beyond just the year in question. Failing to protest your Texas property taxes for even one year can cost you for even the next three years as home sales continue to increase. Lowering your valuation this year effectively sets a lower baseline for future increases. So your efforts now will continue to pay dividends in the future.
Compare the effective property tax rate, median home value, and median tax bill for Dallas, Houston, Austin, and San Antonio to see what some Texas residents are paying annually in property taxes.
Median Effective Property Tax Rate | Median Home Value | Median Tax Bill | |
|---|---|---|---|
Dallas | 1.74% | $309,600 | $5,040 |
Houston | 1.41% | $89,420 | $1,317 |
Austin | 1.51% | $237,942 | $2,796 |
San Antonio | 2.03% | $265,000 | $5,362 |
Step-by-Step Guide to Texas Property Tax Protest
Filing a tax protest can be a complex task. 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 describing the condition of the property.
Confirm that you have received any exemptions on homestead 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 data for real estate in your area
photos of property depreciation
receipts and repair estimates for the property
reports from a contractor or inspector showing discrepancies
independent appraisals reflecting a different assessment value
record corrections illustrating inaccurate measurements and features
3. File Your Protest (Form 50-132)
Use the Notice of Protest form (Form 50-132) located on the district appraisal website to file a formal protest. Include the evidence you've gathered. The deadline to file is May 15 or 30 days after the appraisal notice was mailed to you, whichever comes later. If you miss the deadline, you will have to wait until the following tax year to file.
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.
