Why Texas Property Taxes Are So High

Texas has some of the highest effective property tax rates in the United States, typically averaging 2.0% to 2.5% of assessed value depending on the county and city. On a $400,000 home in the Houston area, that is $8,000 to $10,000 per year in property taxes. In Austin and Dallas, where home values are higher, the annual tax bill can exceed $15,000 to $20,000.

Those taxes fund county government, city services, and most critically, local school districts. Texas school funding is heavily reliant on property tax revenue, which is one reason rates are so high and why local appraisal districts are under constant pressure to maximize assessed values.

Every Texas county has an appraisal district, an independent agency responsible for assessing the value of every taxable property in the county once per year. That appraisal district does not set your tax rate. But it sets the assessed value that every taxing entity multiplies their rate against. Get your assessment down, and every single taxing unit's charge goes down proportionally.

Your Two Legal Protest Strategies

Texas law gives property owners two distinct grounds for protesting their assessment. You can use either or both. Understanding the difference is essential to choosing your strongest argument.

Strategy 1: Market Value Protest

A Market Value protest argues that your home's appraised value is higher than what it would sell for on the open market. You are saying: "My home is worth less than the appraisal district thinks."

This is the strategy most homeowners default to, and it is the harder one to win. To succeed, you need to show evidence that your home would sell for less than the assessed value. In markets where prices have been rising, appraisers are well-positioned to defend their numbers with recent comparable sales.

Market Value protests are most effective when the market has clearly declined, when your home has specific functional issues (foundation problems, outdated systems, deferred maintenance), or when DCAD, HCAD, or TCAD has simply made an obvious factual error in your property record.

Strategy 2: Unequal Appraisal (The Texas Advantage)

Section 41.41(a)(2) of the Texas Property Tax Code gives you the right to protest on the basis of unequal appraisal. This means you are arguing not that your home is worth less, but that your home is being taxed at a higher rate per square foot than comparable homes in your area.

Read that again carefully. You are not saying your home's value is wrong. You are saying your neighbors with similar homes are assessed lower than you, and that inequality violates the law.

This is Texas's most powerful and underused protest strategy. It works even when the market is strong. It works even when your home's value has gone up. It works whenever your assessment per square foot is higher than neighboring comparable homes, regardless of whether those homes' assessed values are accurate.

The Legal Foundation

Section 41.43(b)(3) of the Texas Property Tax Code states that to establish unequal appraisal, a property owner must show that the appraisal ratio of their property exceeds by at least 10% the median appraisal ratio of a reasonable and representative sample of comparable properties. In practice, this means you need comparable homes assessed at a meaningfully lower ratio than yours.

Why Unequal Appraisal Wins More Often in Texas

Texas appraisal districts use mass appraisal models to value hundreds of thousands of properties simultaneously. These models are built on broad market trends and cannot account for the condition, features, and specific characteristics of every individual home. The result is that homes with similar specifications often end up with different assessed values per square foot depending on which data bucket the algorithm put them in.

That creates equity gaps within the same neighborhood, sometimes within the same block. And those gaps are your legal opportunity.

Because Unequal Appraisal is a math argument rather than an opinion argument, it is much harder for the Appraisal Review Board to dismiss. You present the assessed values of comparable homes from the appraisal district's own records. The Board cannot argue with numbers pulled directly from their own system.

The Texas Property Tax Protest Process: Step by Step

Step 1: Check Your Current Assessment

Your county appraisal district mails a Notice of Appraised Value between March and April each year. You can also look up your assessment online at your county's appraisal district website at any time. The key number is your Appraised Value, which is what your tax rate is applied to.

If you have a Homestead Exemption, your appraised value is capped at 10% growth per year, even if your market value rises faster. This is called the Homestead Cap. But even with the cap, your base assessed value can still be higher than your neighbors' relative to square footage, making Unequal Appraisal still viable.

Step 2: Gather Comparable Properties

This is the core of your case. For an Unequal Appraisal protest, you need to find properties similar to yours that the appraisal district has assessed at a lower rate per square foot. Strong comparables share these characteristics:

Location: Within your subdivision or within 0.25 to 0.45 miles of your home (varies by county and urban density)
Size: Within 12% to 15% of your home's square footage
Age: Built within 8 to 10 years of your home's construction date
Assessment: Assessed at a lower value per square foot than your property

To find these, search your county appraisal district's public records. For each candidate, record the address, square footage, year built, and current appraised value. Divide the appraised value by the square footage to get the assessed rate in dollars per square foot. Any property where that rate is lower than yours is a potential comparable.

Aim for five to eight comparables. Three is the minimum to establish a pattern. The more you have, the stronger your argument becomes.

Step 3: File Your Protest Before the Deadline

The Texas property tax protest deadline in 2026 is May 15 or 30 days after the date your appraisal district mails your Notice of Appraised Value, whichever comes later. Most counties use May 15 as the standard cutoff.

File online through your county's appraisal district portal, or submit Form 50-132 (Notice of Protest) by mail. When selecting grounds, always check "Unequal Appraisal of Property" under Section 41.41(a)(2). You can also check Market Value if that applies, but Unequal Appraisal is often your stronger ground.

Step 4: The Informal Conference

After you file, your county appraisal district will schedule an informal conference before your formal ARB hearing. This is usually a short phone call or video meeting with an appraiser from the district. Many cases settle here.

The informal conference is not a hearing. You are having a conversation with an employee of the appraisal district, not a judge. Present your comparable properties clearly and make your request specific.

What to Say at the Informal Conference

"I am protesting under Unequal Appraisal, Section 41.41(a)(2). My property at [address] is currently assessed at [your $/sqft]. I have identified [number] comparable properties within [distance] that are assessed between [low] and [high] per square foot. The median comparable assessment is [median $/sqft]. I am requesting a reduction to [target value] to bring my assessment in line with these comparable properties. I have an evidence packet with all the data."

Step 5: The ARB Hearing (If Needed)

If you do not reach a satisfactory settlement at the informal conference, you proceed to a formal Appraisal Review Board hearing. The ARB is a panel of three to five citizen volunteers who are not employees of the appraisal district. They hear your evidence and the appraisal district's evidence and make a determination.

The ARB hearing is more formal than the informal conference, but it is not a court proceeding. There is no judge, no opposing counsel, and no strict rules of evidence. You present your comparable properties grid, state your requested value, and explain why the equity gap between your assessment and your comparables violates the uniform and equal standard required by law.

The presentation at an ARB hearing follows the same script as the informal conference, but you may be asked follow-up questions. Keep your answers brief and data-focused. The ARB is looking at numbers, not listening to stories about how hard it is to pay your tax bill.

County-by-County Guide: Texas's Largest Markets

The protest process follows the same Texas Property Tax Code in every county, but each appraisal district has different online portals, hearing procedures, and comparable radius guidelines. Here are the five largest Texas counties:

Harris County (Houston) — HCAD appraises over 1.8 million properties. Filing is done through hcad.org iFile system. Recommended comparable radius: 0.3 miles, within 12% square footage.
Dallas County — DCAD covers 800,000+ properties. File at dcad.org. Recommended comparable radius: 0.35 miles, within 12% square footage.
Travis County (Austin) — TCAD covers the Austin metro. File at traviscad.org iFile. Recommended comparable radius: 0.4 miles, within 15% square footage.
Tarrant County (Fort Worth) — TAD covers Fort Worth and Arlington. File at tad.org. Recommended comparable radius: 0.4 miles, within 15% square footage.
Bexar County (San Antonio) — BCAD covers the San Antonio metro. File at bcad.us. Recommended comparable radius: 0.4 miles, within 15% square footage.

What Happens If You Miss the Deadline

Missing the protest deadline in Texas means losing your right to challenge your assessment for that tax year. There are no exceptions, no hardship extensions, and no appeals of the deadline itself. The Texas Property Tax Code is strict: file by the deadline or accept the assessment.

This is not a technicality. Counties have tested it extensively in court. The deadline is firm.

If you miss the deadline this year, your best move is to begin the comparable property research now so you are ready to file immediately next year. Many homeowners who file in year one see reductions that hold through the Homestead Cap for years afterward.

How Much Can You Save?

The savings range widely based on your county, your current assessment, and the strength of your comparable evidence. In Texas's primary markets:

Harris County: Successful protests average $800 to $1,800 per year in savings
Travis County: Successful protests average $1,200 to $2,400 per year
Dallas County: Successful protests average $900 to $1,600 per year
Tarrant County: Successful protests average $700 to $1,400 per year

These are first-year figures. With the Homestead Cap, a lower base assessment continues to compound savings over time. A $1,200 first-year savings can easily translate to $10,000 to $15,000 in cumulative savings over ten years.

Should You Hire a Property Tax Consultant?

Texas has a large industry of property tax consultants and protest firms. Most charge contingency fees of 25% to 40% of the first year's savings. Some charge annual fees for ongoing service.

These services make sense for homeowners who do not want to do any research or attend any hearings. But the math is straightforward: if a firm saves you $1,500 and takes 33%, you net $1,000. If you do it yourself with a $99 evidence packet, you net $1,401.

The research and presentation are not complicated. The strategy is well-documented in Texas law. The evidence is publicly available. What you need is the right comparable data, formatted correctly, ready to present before May 15.
