How to Protest Your Property Tax Assessment in 2026

Quick Answer

To protest your property taxes in Texas, file Form 50-132 (Notice of Protest) with your county appraisal district before May 15, 2026, or within 30 days of receiving your Notice of Appraised Value, whichever is later. 

Texas law guarantees every property owner the right to challenge their assessed value,  and between 60% and 80% of protests statewide result in a reduction. In major metropolitan counties, the median Texas homeowner who wins a protest saves approximately $606 per year.

Over 51% of Texas homes are currently overassessed, meaning more than half of all Texas property owners are paying more in property taxes than they should. 

Yet in major metros like Dallas-Fort Worth, 71% of homeowners didn't file a protest in 2025, according to Ownwell's 2025 DFW protest analysis. 

In Houston, 68% of residential property owners left money on the table. While in San Antonio, that number climbed to 78%.

This guide gives you everything you need to change that — grounded in Texas Tax Code, 2025-2026 legislative reforms, and real protest outcome data from across the state.

What Is a Property Tax Protest in Texas?

A property tax protest is a formal legal challenge to the assessed value your county appraisal district assigns to your property. You file with the Appraisal Review Board (ARB), an independent panel of citizens authorized under the Texas Property Tax Code to resolve disputes between property owners and appraisal districts.

A few key terms to understand before you begin:

• Assessed value (appraised value): The dollar amount your county appraisal district assigns to your property as of January 1 of the tax year. In Texas, properties are assessed at 100% of market value — there is no fractional assessment.

• Market value: What your property would realistically sell for in an arm's-length transaction as of January 1.

• Taxable value: Your assessed value minus any applicable exemptions (e.g., homestead, over-65, disabled veteran). This is the number your tax rate is applied to.

• Uniform and equal: A Texas-specific protest basis under Tax Code Section 41.43 that allows you to protest not just market value, but whether your property is appraised equitably compared to similar properties, even if the value is technically "correct."

Important reminder: You are protesting your property's assessed value, not the tax rate. The rate is set by local taxing units (school districts, counties, cities, MUDs) and is not subject to protest.

Why Texas Homeowners Should Protest Every Year

Texas Has Some of the Highest Effective Property Tax Rates in the Country

Texas has no state income tax, and it funds government services primarily through property taxes. The result: effective property tax rates averaging 1.6% to 2.5%, depending on county and school district, among the highest in the nation. On a $400,000 home with a 2% effective rate, that's $8,000 per year in property taxes before exemptions.

County Appraisal Districts Use Mass Appraisal, Producing Individual Errors

Appraisal districts use computer-assisted mass appraisal (CAMA) models to value hundreds of thousands of properties simultaneously. 

These models rely on broad assumptions about neighborhoods and property types. 

They cannot account for your specific home's condition, location disadvantages, deferred maintenance, or recent comparable sales that support a lower value, which is exactly why individual protests succeed.

The 10% Appraisal Cap Works Better When You Protest

Texas homestead properties are subject to a 10% annual appraisal cap. Meaning your appraised value cannot increase by more than 10% per year, regardless of actual market conditions.

Over several years, these compounds have led to substantial savings. Learn more in our deep dive on how the appraisal cap interacts with protests.

What Ownwell's Data Shows About Non-Protestors

Ownwell's three-year study across seven densely populated Texas counties found that homeowners who successfully protested consistently maintained lower market values year-over-year than those who didn't — meaning the appraisal district continued assigning higher values to non-protestors. 

In Dallas County alone, the year-over-year difference in market value between non-protestors and successful protestors reached 6.46% by 2024.

Texas Property Tax Protest Deadline 2026

The standard deadline to protest property taxes in Texas is May 15, 2026.

If your Notice of Appraised Value is mailed after April 15, 2026, you have 30 days from the date the notice was mailed, whichever date is later. 

Always check the specific deadline printed on your notice; that date controls.

Key 2026 protest calendar:

Missing the May 15 deadline forfeits your right to protest for the entire 2026 tax year. There are very limited exceptions.

Do not wait until the last minute — online filing systems for major counties, such as HCAD and DCAD, frequently experience traffic spikes near the deadline.

How to Protest Property Taxes in Texas: Step-by-Step

Step 1: Review Your Notice of Appraised Value

Your county appraisal district will mail your Notice of Appraised Value in late March through early May. This notice contains:

• Your property's assessed (appraised) value for 2026

• Your property details (square footage, lot size, bedrooms, bathrooms, year built)

• Your filing deadline

• Your iFile PIN or account number for online filing

Review the property details carefully. Errors in square footage, bedroom counts, lot size, or property condition are more common than most homeowners expect, and each error can inflate your assessed value.

If you didn't receive a notice, you can look up your property on your county appraisal district's website. Not receiving a notice does not extend your filing deadline.

Step 2: Determine If You Have Grounds to Protest

Texas law provides two primary bases for protest under Tax Code Chapter 41:

1. Market Value (Incorrect Appraised Value) Your assessed value is higher than what your property would actually sell for as of January 1, 2026. This is established using recent comparable sales (comps) of similar properties in your area.

2. Uniform and Equal (Equity) Even if your assessed value reflects market value, your property is appraised at a higher value per square foot (or per similar unit) than comparable properties in your appraisal district. 

Texas Tax Code Section 41.43 requires that all properties be appraised uniformly and equitably. This is a powerful and often underused basis — especially in Texas's non-disclosure environment, where recent sales data can be limited.

Other valid protest grounds include:

• Errors in your property record (wrong square footage, incorrect bedroom/bath count, inaccurate lot size)

• Failure to receive a required notice

• Denial or modification of an exemption

• A recent arm's-length purchase of your property at a price lower than the assessed value

Step 3: Gather Your Evidence

Strong evidence is what separates a winning protest from a losing one. Here's what carries the most weight, in order of impact:

Comparable Sales Data (Market Value Protest): Recent sales of properties similar to yours in location, size, age, and condition. The stronger comps are:

• Within your neighborhood or subdivision (same school district preferred)

• Sold within the past 6-12 months of January 1, 2026

• Similar in square footage (within 15-20%), lot size, year built, and condition

Because Texas is a non-disclosure state, accessing verified sales data can require working with a real estate agent for a Comparative Market Analysis (CMA), or using a professional protest service with direct MLS access.

Equity Comparables (Uniform and Equal Protest): A grid showing similar properties within your appraisal district with their assessed values per square foot. 

If the district assesses your home at $180/sq ft but comparable properties average $150/sq ft, that's a strong equity argument. Your appraisal district's own data — pulled from their public property search — is the source for this analysis.

Documentation of Condition Issues: Photos of deferred maintenance, foundation issues, water damage, outdated systems, or other features that would reduce what a buyer would pay. 

Date-stamp your photos. Contractor estimates, or invoices for needed repairs, significantly strengthen the case.

A Recent Independent Appraisal: For high-value properties or complex cases, a licensed appraiser's opinion of value provides authoritative third-party support. 

Factor in the cost ($400-$600 typically) against your potential tax savings before commissioning one.

Corrected Property Record: If you found errors in your property details, request your property record card from the appraisal district and document the corrections with supporting evidence (floor plan, survey, permit records).

Step 4: File Your Protest Before the Deadline

Filing methods vary by county. Most major Texas appraisal districts now offer online filing:

You can also file by mail using Form 50-132 (Property Owner's Notice of Protest), available from the Texas Comptroller or your county appraisal district. 

If mailing, the envelope must bear a postmark no later than May 15, 2026.

When completing Form 50-132, select "incorrect appraised (market) value and/or value is unequal compared with other properties" as your reason for protest. This preserves the widest range of evidence options and the broadest post-ARB appeal rights.

Step 5: Attend the Informal Review (Do Not Skip This)

After filing, most appraisal districts will offer an informal review or a one-on-one meeting (increasingly by phone or online) with an appraiser before your formal ARB hearing. Most protests that succeed are resolved at this stage. 

This is where you present your evidence and negotiate a value.

• Bring organized copies of your comparables, photos, and any record corrections

• Be specific: "Comparable at [address] sold for $X on [date], at $Y per square foot."

• Be willing to negotiate. You may not get to zero, but a partial reduction compounding over years is still meaningful

• If you receive an iSettle offer (common in Harris County), review it carefully before accepting or rejecting

Step 6: Present Your Case at the ARB Hearing (If Needed)

If informal review doesn't resolve your case, you'll attend a formal hearing before the Appraisal Review Board. Thanks to HB 1533, you can now attend remotely by phone or video in most counties.

ARB hearings typically last 15-30 minutes. A panel of citizen board members will hear evidence from both you and the appraisal district. Key things to know:

• The ARB cannot raise your value as a result of your protest under Texas law. Your value can only stay the same or go down. There is zero downside risk to filing.

• Lead with your strongest evidence. Boards respond to data, not emotional appeals.

• Bring three copies of all evidence: one for you, one for the board, and one for the appraisal district representative.

• The appraisal district must give you access to their evidence at least 14 days before your hearing — review it carefully and be prepared to address their methodology.

• In counties with populations over 1.2 million (Harris, Dallas, Tarrant, Bexar, Travis), special ARB panels now handle complex property protests.

Step 7: Review the Decision and Know Your Appeal Options

You'll receive a written ARB order by email (if you provided an email address) or certified mail, typically within a few weeks of your hearing. The order shows your property's determined value.

If you're unsatisfied with the ARB's decision, Texas law provides further appeal options:

2025 County-Level Texas Protest Data

Ownwell's analysis of 2025 protest activity across Texas's largest markets reveals a consistent story: most homeowners didn't protest, and those who did saved meaningful money.

Houston Metro (Harris, Fort Bend, Galveston, Montgomery, Waller Counties)

• 68% of homeowners did not protest — over 1.4 million residential properties accepted their appraisal without challenge

• Harris County alone had 866,623 unprotested properties

• Montgomery County led the region with the highest protest rate (45% of residential properties filed)

Dallas-Fort Worth Metro (Collin, Dallas, Denton, Rockwall, Tarrant Counties)

• 71% of DFW residential properties, 1.48 million homes, did not file protests in 2025

• Dallas County alone had 519,000 unprotested properties, the single largest concentration of potential unclaimed savings in North Texas

• Rockwall County delivered the second-highest average savings at $1,049 per successful protest, despite being the smallest county in the analysis

• Denton County homeowners showed the highest DIY rate in the metro at 22%

See the full 2025 DFW protest data →

San Antonio Metro (Bexar, Comal, Guadalupe Counties)

• 77% of San Antonio-area homeowners, over 614,000 properties, did not protest in 2025

• In Bexar County (San Antonio), only 1 in 5 homeowners challenged their appraisal

• Comal County homeowners achieved the region's highest average savings: $1,160 per successful protest

The Three-Year Compound Cost of Not Protesting

Ownwell's 2023-2025 Texas protest vs. non-protest study — analyzing millions of residential properties across 17 high-density Texas counties — found that homeowners who skip their annual protest don't just miss one year of savings. 

They miss compounding savings as their values diverge further from those who successfully protested each year.

 Key findings:

• Statewide across 17 counties, $3.3 billion in potential tax savings went unclaimed over the three-year period — nearly 1.5x the amount actually saved by those who did protest

• Bexar County (San Antonio) non-protestors left an estimated $352.9 million in potential savings on the table from 2023–2025

• Collin County non-protestors missed an estimated $127.2 million in potential savings over three years

• Tarrant County (Fort Worth) non-protestors missed $449 million over the same period — the largest missed savings total in the DFW metro

When to Protest Property Taxes Yourself vs. Hiring a Professional

DIY Protests Work Well When:

• Your case involves a straightforward factual error (wrong square footage, incorrect bedroom count)

• Your property is a standard single-family home in a subdivision with abundant comparable sales

• You have time to research comps, prepare evidence, and attend hearings

• The potential savings are modest relative to professional fees

Professional Representation Makes Sense When:

• You own commercial property (no annual appraisal cap, more complex valuation methods)

• You manage multiple properties

• Your county is large and/or the CAD is aggressive (Harris, Dallas, Tarrant, Williamson)

• You lack access to MLS or comparable sales data (remember: Texas is a non-disclosure state)

• You don't have 8-15 hours to invest in research, evidence preparation, and hearings

• You want to ensure you don't miss deadlines or procedural requirements

How Contingency-Based Services Like Ownwell Work

Ownwell operates on a pure contingency model — you pay nothing unless you save money. There are no upfront fees, no mandatory enrollment charges, and no flat fees. 

Our fee is 25% of your first year's savings — one of the lowest contingency rates among major Texas protest companies (competitors typically charge 30-50% and, in some cases, require mandatory upfront fees).

After you submit your address, Ownwell's local Texas property tax experts:

1. Analyze your property and run both market value and uniform-and-equal analyses

2. Build your evidence package using verified comparable sales and equity data

3. File your protest before the deadline

4. Attend informal reviews and ARB hearings on your behalf

5. Evaluate further appeals if the ARB result warrants it

Note that we decline to file your protest if its market data analysis indicates the evidence doesn't support a reduction — protecting you from wasting time on a case unlikely to win, unlike some competitors who will take on your case with an upfront fee to ensure they’re paid.

Common Mistakes That Cost Texas Homeowners Money

1. Missing the filing deadline. 

The May 15 deadline is absolute for most homeowners. There are very limited statutory exceptions (failure to receive notice in certain circumstances). Once it passes, you wait a full year.

2. Only protesting market value when equity is the stronger argument. 

In Texas's non-disclosure environment, building a market value case without MLS access is difficult. An equity analysis — showing your property is assessed at a higher rate per square foot than neighbors — is often an easier case to win and doesn't require verified sales prices.

3. Accepting the first iSettle offer without evaluating it. 

Informal settlement offers from appraisal districts are a starting point, not the final word. Review the offer against your evidence before accepting.

4. Failing to protest just because you got a homestead exemption. 

The homestead exemption reduces your taxable value, not your appraised value. If your appraised value is too high, you're still overpaying even with the exemption applied.

5. Not protesting because your value didn't increase. 

Even if your value stayed flat this year, you may still be paying taxes on an overassessed property relative to comparable homes. The equity analysis applies regardless of year-over-year change.

6. Using automated online valuations (Zestimates, Redfin) as evidence. 

ARBs do not accept algorithm-generated online estimates. Use actual comparable sales data or a licensed appraisal.

2026 Texas Property Tax Legislative Updates

The 89th Texas Legislature passed significant property tax relief measures in 2025. Here's what's in effect for the 2026 protest season:

SB 4: $140,000 Homestead Exemption (Approved by Voters, November 2025)

The mandatory school district homestead exemption increased from $100,000 to $140,000, effective for the 2025 tax year and forward. 

If you have a homestead exemption on file, your school district taxable value automatically drops by an additional $40,000. 

Note: this is applied automatically; you do not need to reapply if your exemption is already on file.

Even with the $140,000 exemption, if your appraised value is too high, you're still overpaying. Exemptions reduce taxable value, not appraised value. A successful protest reduces both.

SB 23: $60,000 Increased Senior and Disabled Exemption

Homeowners aged 65 and older, or disabled, now receive an additional $60,000 school district exemption (up from $10,000). 

Combined with the standard $140,000 exemption, qualifying seniors now have $200,000 in school district exemptions.

HB 1533: Appraisal Review Board Reform (More Homeowner-Friendly ARB Hearings)

This is the most significant procedural change for property owners protesting in 2026. HB 1533 introduces:

• Enhanced transparency requirements for appraisal districts in the evidence they must disclose

• 15-day notice requirement for good cause hearings (up from 5 days), giving you more time to prepare

• Remote hearing access means you can now attend ARB hearings by phone or video in most counties

• Expanded binding arbitration rights for tenants contractually obligated to pay property taxes on properties valued up to $5 million

• Appraisal districts must ensure that at least one taxpayer representative is included in property tax trainer certification programs

The practical effect: HB 1533 slightly tilts the balance in favor of the property owner during the formal hearing process.

HB 8: Temporary School Tax Rate Compression

A temporary, one-year reduction of $0.0331 per $100 of value on school district tax rates for 2025-2026. This is on top of the existing Prop 4 compression from 2023. It expires September 1, 2027, unless extended by the legislature.

HB 9: Business Personal Property Exemption

Up to $125,000 of business personal property (equipment, inventory, and other business property) is now exempt from taxation by all taxing entities.

SB 850: Overpayment Refund Protections

Establishes firm deadlines and automatic triggers for processing overpayment refunds from taxing units — an important protection if you successfully protest after already paying your bill.

Texas Property Tax Protest FAQs

What is the deadline to protest property taxes in Texas in 2026

 May 15, 2026, or 30 days from the date your Notice of Appraised Value was mailed — whichever is later. Always check the date printed on your notice, as it controls your specific deadline.

Can my property value be increased because I protested? 

No. Under Texas Tax Code Section 41.43, the Appraisal Review Board cannot increase your property's appraised value as a result of a protest you filed. 

Your value can only stay the same or go down. There is zero financial downside risk to filing a protest in Texas.

How much does it cost to protest property taxes in Texas? 

Filing a protest yourself is free. Hiring a contingency-based service like Ownwell costs nothing upfront — you pay only if you save money. Professional appraisals, if needed, typically cost $400-$600 and may make sense for high-value properties.

What is the success rate for property tax protests in Texas? 

Statewide, between 60% and 80% of Texas property tax protests result in a reduction. Success rates vary by county and depend heavily on the quality of evidence presented. 

At informal review (the stage before the formal ARB hearing), settlement rates are generally higher, making strong evidence preparation especially important.

How much can I save by protesting property taxes in Texas? The median Texas homeowner who successfully protests saves approximately $606 per year. However, savings vary significantly by county, home value, and local tax rates.

On a $400,000 home with a 2% effective tax rate, a 10% reduction in assessed value saves approximately $800 per year. Savings compound in future years as the reduced value becomes the starting point for the 10% appraisal cap.

Can I protest property taxes in Texas every year? 

Yes. Texas law allows you to file a protest each year after you receive your assessment notice. 

Annual protests are recommended because each successful reduction lowers your baseline for the 10% homestead cap, creating compounding savings over time.

What is a uniform and equal protest in Texas? 

A uniform and equal protest argues that your property is appraised at a higher rate than comparable properties — even if the assessed value might reflect market conditions. 

It is based on Texas Tax Code Section 41.43 and is one of the most powerful and underused protest strategies in Texas.

What happens after the ARB issues its decision? 

You receive a written order with the ARB's determined value. If you accept it, your tax bill is adjusted accordingly. 

If you disagree, you can file for binding arbitration (for properties valued up to $5 million), appeal to the district court, or appeal to SOAH (for properties over $1 million), all within 60 days of the ARB's final order.

Does a successful protest affect my future assessed value? 

Yes — favorably. A lower value in 2026 becomes the starting point for the 10% cap calculation in 2027 and beyond. 

Additionally, if you successfully protest through a formal ARB hearing, the appraisal district must have "clear and convincing evidence" to raise your value significantly in the following year, creating an additional layer of protection.

Do I need a lawyer to protest property taxes in Texas? 

No. You can represent yourself at the ARB. However, if you hire a property tax consultant or agent, they must have a signed Form 50-162 (Appointment of Agent) authorizing them to represent you. 

A licensed real estate agent can also prepare evidence and represent you at an ARB hearing for single-family residential properties with a completed authorization form.
