Texas Property Tax Protest Guide (2026)
Updated March 2026 · 20 min read
Texas homeowners can protest their property tax appraisal every year by filing Form 50-132 with their county appraisal district before May 15 (or 30 days after your notice is mailed, whichever is later). Texas uses the term “protest” rather than “appeal.” The process involves an informal hearing, then a formal Appraisal Review Board (ARB) hearing if needed. Success rates are high — above 70% in Harris and Travis counties. Below, we walk through every step of the Texas protest process with specific forms, deadlines, evidence strategies, and county-by-county filing guides for the 10 largest counties.
What Is a Property Tax Protest in Texas?
A property tax protest is the formal process Texas homeowners use to challenge their property’s appraised value. While most states call this an “appeal,” Texas uses the term “protest” — and the process reflects that distinction. You’re not asking a court to review a decision. You’re protesting the value your county appraisal district (CAD) assigned to your property.
The Texas Comptroller of Public Accounts oversees the property tax system statewide. Each of the 254 counties has its own appraisal district that determines property values. When you disagree with your value, you file a protest with your local CAD — not with the state. See our property tax appeal glossary entry for how the process compares across states.
Why Texas Property Tax Protests Are Different
Texas has no state income tax, which means local governments rely heavily on property taxes to fund schools, roads, and emergency services. As a result, Texas property tax rates rank among the highest in the nation — the U.S. Census Bureau’s American Community Survey consistently places Texas in the top 10 for effective property tax rates.
Texas also differs in terminology and process. The state uses “protest” rather than “appeal,” filings go to county appraisal districts (CADs) rather than assessor’s offices, and hearings are conducted by Appraisal Review Boards (ARBs) rather than boards of equalization. The statewide process is governed by the Texas Property Code, but each county operates its own appraisal district independently.
Texas uses a 100% assessment ratio, meaning your appraised value should equal fair market value. This makes comparable sales comparisons straightforward — sale prices compare directly to your appraised value without any ratio adjustment. If similar homes in your neighborhood sold for less than your appraised value, you have strong grounds to protest.
Who Should Protest?
You should protest your property taxes if any of the following apply:
- Your appraised value exceeds market value. If comparable homes in your area are selling for less than your appraised value, you’re likely overassessed.
- Your value increased significantly. Even if your value is correct, a large year-over-year increase is worth challenging — appraisal districts sometimes apply blanket increases that don’t reflect individual property conditions.
- Similar properties are appraised lower. Texas law requires uniform appraisal. If your neighbor’s comparable home is appraised at $350,000 and yours at $400,000, you have grounds for an “unequal appraisal” protest.
- Your property has condition issues. Foundation problems, roof damage, outdated systems, or flood damage reduce market value. If the appraisal district hasn’t accounted for these, protest.
- The property record has errors. Wrong square footage, extra bedroom counted, incorrect lot size — these errors are more common than you’d expect and directly inflate your value.
Since Texas appraises at 100% of market value, the math is simple: look up what your home would actually sell for today. If that number is below your appraised value, you should protest. Use our free overassessment calculator to estimate your potential savings.

Texas Property Tax Protest Deadlines
The standard protest deadline is May 15 or 30 days after your Notice of Appraised Value is mailed, whichever is later. This applies to all 254 Texas counties.
Key detail: Your deadline is based on the mailing date on your notice, not the date you received it. Check the mailing date printed on your notice. If it was mailed April 20, your deadline is May 20 (30 days later) — not May 15.
Late protest provisions: Texas does allow late protests in limited circumstances. You may file a late protest if you can show “good cause” (illness, military deployment, the appraisal district made a clerical error). Late protests must be filed before the appraisal roll is certified, typically in late July. However, don’t rely on this — file on time. See our Texas state page for more deadline details.
The Texas Property Tax Protest Process: Step by Step
Step 1: Receive Your Notice of Appraised Value
Texas appraisal districts mail Notices of Appraised Value between late March and mid-April. This notice shows your property’s new appraised value, the previous year’s value, your exemptions, and the deadline to file a protest. If your value increased — or if you believe it exceeds market value even without an increase — you have grounds to protest.
Step 2: File Form 50-132 (Notice of Protest)
Form 50-132 is the official Texas protest form, available from the Comptroller’s website or your county appraisal district. You need:
- Your property ID number (from your notice)
- The reason for your protest — most homeowners check “Value is over market value”
- Your opinion of your property’s market value
- Whether you want an informal hearing (yes — always say yes)
Most Texas counties accept online filings. Harris County (Houston) uses their iFile system. Travis County (Austin), Bexar County (San Antonio), Dallas County, Tarrant County (Fort Worth), and Collin County all have online filing portals. Filing online creates an instant confirmation — keep this as proof of your timely filing.
Step 3: Gather Your Evidence
The strength of your protest depends entirely on your evidence. Texas ARBs respond to data, not arguments about tax burden or affordability. Your evidence package should include:
- Comparable sales: 3-5 recent sales of similar homes within your neighborhood or nearby subdivisions. Since Texas uses a 100% ratio, sale prices compare directly to your appraised value. Focus on homes that sold for less than your appraised value. See our guide on finding comparable sales.
- Condition documentation: Photos of deferred maintenance, foundation issues, aging roofs, outdated interiors, or flood damage. Appraisal districts assume standard condition unless you prove otherwise.
- Repair estimates: Written estimates from contractors for needed repairs. A $15,000 foundation repair or $12,000 roof replacement directly supports a lower value.
- Neighborhood factors: Documentation of nearby construction, road noise, commercial encroachment, or other factors that reduce desirability. Google Maps screenshots with annotations work well.
- Equity comparisons: If similar properties on your street are appraised lower, the appraisal district is required to appraise uniformly. Pull the appraised values of comparable homes from your CAD’s website.

Step 4: Attend the Informal Hearing
After filing your protest, your appraisal district will schedule an informal hearing — a one-on-one meeting with an appraiser from the district. This is not a courtroom. It’s a conversation where you present your evidence and the appraiser presents theirs.
Many protests are resolved at this stage. The appraiser has authority to reduce your value if your evidence supports it. Come prepared: bring printed copies of your comparable sales, photos, and any repair estimates. Be professional and stick to the data. The appraiser is evaluating your evidence, not your frustration with taxes.
Pro tip: If the appraiser offers a reduction, ask what comparable sales they used and what value they’re proposing. You’re not obligated to accept their first offer. If their proposed value is still above what your evidence supports, you can decline and proceed to the formal ARB hearing.
Step 5: The Formal ARB Hearing
If the informal hearing doesn’t resolve your protest, you’ll be scheduled for a formal hearing before the Appraisal Review Board. The ARB is an independent panel (typically 1-3 members) appointed by the local administrative district judge. They are not employed by the appraisal district.
The ARB hearing follows a structured format:
- Both parties are sworn in
- You present your evidence (5-15 minutes depending on county)
- The appraisal district presents their evidence
- Both sides can ask questions and rebut
- The panel deliberates and issues a determination
Many Texas counties now offer phone or video hearings as alternatives to in-person attendance. Check your county’s options when scheduling. Harris County, Travis County, and most large metro counties offer remote hearing options.
The ARB’s decision is binding unless you appeal further to district court or binding arbitration. For residential properties valued under $5 million, binding arbitration (a $550 deposit, refundable if you win) is often the more practical option.
Step 6: Post-Hearing Options
If the ARB rules against you or offers an insufficient reduction, Texas law provides two further options:
- Binding arbitration: File within 60 days of the ARB order. Costs $550 (refundable if you win). An independent arbitrator reviews both sides’ evidence. Available for residential properties under $5 million.
- District court: File within 60 days. Requires an attorney and court costs. Makes sense for high-value properties or complex valuation disputes.
What to Say (and Not Say) at Your Texas Protest Hearing
The hearing is about evidence, not emotion. Here’s a framework for presenting your case effectively:
Do Say
- “I have [X] comparable sales within [distance] of my property that sold for less than my appraised value.”
- “The average sale price per square foot in my area is $[X], which puts my home’s value at $[Y].”
- “My property has [specific condition issue] that reduces its value. Here are photos and a repair estimate.”
- “Similar properties on my street are appraised at $[X], while mine is appraised at $[Y]. I’m requesting uniform appraisal.”
Don’t Say
- “My taxes are too high” — the ARB sets values, not tax rates
- “I can’t afford this” — financial hardship isn’t a valuation argument
- “My Zillow estimate says...” — algorithmic estimates aren’t evidence
- “This isn’t fair” — fairness arguments without data don’t result in reductions

Texas Homestead Exemption and the 10% Cap
If you have a homestead exemption, Texas law caps your appraised value increase at 10% per year (excluding new construction or improvements). This means even if market values jump 25%, your taxable value can only increase 10% annually. The cap applies to the appraised value used for tax calculation, not the market value the district assigns.
Important: Protesting your market value is still worthwhile even with the 10% cap. A lower market value today means a lower starting point for future 10% caps. If you don’t protest and the district sets your market value at $500,000 when it should be $450,000, that $50,000 overage compounds through the cap calculation every year.
If you haven’t filed for homestead exemption, do it now — it’s free and can be filed at any time. In addition to the 10% cap, it provides a $100,000 exemption from school district taxes (as of the 2023 Prop 4 increase). Over-65 homeowners get an additional $10,000 school district exemption plus a tax freeze — your school taxes cannot increase above the amount you paid the year you turned 65. See our exemptions guide and homestead exemption explainer for details. For a complete breakdown of how the cap works, including the 20% cap for non-homestead properties, read our guide on how much property taxes can increase in Texas.
Grounds for Protesting in Texas
Texas Tax Code Section 41.41 lists the grounds for protest. The most commonly used for residential properties:
- Market value is too high (Section 41.41(a)(1)): Your appraised value exceeds fair market value based on comparable sales. This is the most common and strongest basis for protest.
- Unequal appraisal (Section 41.41(a)(2)): Your property is appraised higher than similar properties in the area. You’re arguing for equity — that your value should be consistent with comparable properties.
- Incorrect property description: The appraisal district has incorrect data about your property — wrong square footage, extra bedroom, incorrect lot size. This happens more often than you’d expect.
- Exemption not applied: You qualify for an exemption (homestead, over-65, disability, veteran) that wasn’t applied to your account.

2026 Texas Property Tax Protest Timeline
How Long Do Protest Savings Last?
A successful protest reduces your appraised value for the current tax year. Since Texas reappraises properties annually, the appraisal district will assign a new value next year. However, your reduced value becomes the new baseline. If the district wants to increase your value, they start from the lower number.
With the homestead 10% cap, this matters even more. Lowering your market value today creates a compounding benefit: each future year’s 10% cap is calculated from a lower starting point. This is why experienced Texas homeowners protest every year — consistent protesting keeps your baseline low.
