The Texas Property Tax Protest: How to Challenge Your Appraisal

The single biggest mental shift for a Californian moving to Texas is understanding that your assessed value is not a fixed number. Under California's Proposition 13, your assessed value is largely locked to your purchase price, growing at no more than 2 percent a year. That stability is exactly why most California homeowners never think about their assessment and rarely have any reason to protest.

Texas is the opposite. County appraisal districts reappraise property at or near current market value on a regular cycle, and for homestead properties they often revisit value every year [1][10]. When home prices in Kendall, Bexar, or Comal County run hot, your appraised value can climb quickly, and because your tax bill is a percentage of that value, a higher appraisal is the direct cause of a higher bill.

Here is the important nuance: if you file a homestead exemption, Texas caps the growth in your school district taxable value at 10 percent per year (plus new improvements) [10]. That cap protects you somewhat, but it does not protect you from being appraised at a value that simply does not match what your house would actually sell for. The protest exists precisely to correct that gap.

Texas law gives property owners the right to protest their appraised value, and there are two main arguments that work. The first is market value: you believe your home is worth less than the district says. The second is unequal appraisal: you believe similar homes nearby are assessed at a lower value per square foot than yours [2][9].

Not every property is a good candidate. If the district appraised your home right at what it sold for and the market has been stable, you may not have much of a case. The strongest situations are when a value was pushed up by a recent sale that does not reflect your property's condition, when your home has issues a buyer would discount, or when the district used an appraised method that overshoots what similar homes actually sold for [2][9].

If you just closed on the house, be realistic: arguing the value is higher than market right after you paid market price is a hard sell. In that first year, your more credible grounds is usually unequal appraisal, which requires showing that comparable properties are assessed at a lower rate than yours. After a few years of ownership, the market-value argument becomes stronger as neighborhood sales move around you [9].

If your appraised value changes, the appraisal district is required to send you a written notice of appraised value in the spring, with details on how to protest [1][6]. In most Hill Country counties the notices go out in April. If you do not receive a notice, you can still file a protest if the value went up, but the clock behaves differently, so do not count on that.

This is the number to commit to memory: file by May 15, or within 30 days of the mailing date on your notice, whichever is later [1][2]. If the deadline lands on a weekend or holiday, it moves to the next business day. That gives most homeowners from mid-April to mid-May, which feels short, so start gathering evidence the day the notice arrives rather than the week before the deadline [4][5].

Missing the deadline is costly. Without a good-cause exception, such as illness, a disaster, or military service accepted by the board before the tax rolls are certified in late July, you lose your right to protest that year's value entirely [1][2]. File early.

Filing is straightforward and most counties now make it easy to do online. Many districts accept a signed written statement, and the common state form is the Notice of Protest, Form 50-132, available through the Texas Comptroller [1]. In Bexar County you can file through the BCAD eFile portal; Kendall and Comal accept filings online, by mail, or in person [3][4][5].

One checkbox on the form matters more than people realize: request the appraisal district's evidence package. The district is required to provide you with the evidence, data, and information it will rely on at your hearing, so you can see exactly what comparables or cost figures support your value. Getting that package is how you know what you are arguing against [2][9].

A protest rises or falls on evidence, and the strongest evidence is comparable sales: recent, closed sales of similar homes. Your case is convincing when you can show several properties that sold for meaningfully less than your appraised value, ideally in the same neighborhood or ZIP and close to your home's size and age [2][9].

Here is what a solid comparison looks like in practice:

• Sold within roughly the last 6 to 12 months, the more recent the better.
• In the same neighborhood or ZIP, or as close as the local market allows.
• Within about 10 to 15 percent of your square footage.
• Within about 5 to 10 years of your home's age.
• Similar condition, lot size, and features, with obvious differences adjusted.

Appraisal districts do not always automatically have current sale prices, so you may need to bring them. Your real estate agent can pull closed sales and help you frame the comparison fairly. Photographs of any condition issues, such as an aging roof, settling cracks, or dated interiors, can reinforce a value argument, but the sales data is what carries the most weight [2][9].

Keep your case simple. You do not need a dozen charts. You need a small set of comparable sales, a short written explanation of why your value is too high or unequal, and photos if they help. A clear, well-organized case is far more persuasive than a long, unfocused one.

Most districts start with an informal conference between you and an appraisal staff member. This is not a courtroom. It is a working meeting, often held by phone or video, where you present your comparables and the staff can agree to adjust the value on the spot. In Bexar County the overwhelming majority of residential protests resolve at this informal stage, which is exactly why the process feels so approachable to new homeowners [4][7].

If you and the district cannot agree, you can take the case to a formal hearing before the Appraisal Review Board (ARB), a panel of local citizens who are trained and appointed to make binding decisions [1][2][6]. The district must send you at least 15 days' notice of the hearing date, time, and place, and must mail you the Texas Property Taxpayer Bill of Rights at least 14 days beforehand [1][6]. You can appear in person, by phone or video, or submit your evidence in writing.

The ARB can lower your value, uphold it, or in theory raise it, though the last is rare and almost never happens in a routine residential protest. Most cases settle before this stage; of those that go to a hearing, many homeowners appear with their comparables and let the evidence speak [1][9].

If you disagree with the ARB's order, Texas gives you two further paths: you can appeal to district court within 60 days of receiving the order, or you can request binding arbitration, which is usually faster and cheaper than litigation [1][9]. These steps are worth knowing but are rare for a typical homeowner, most of whom resolve their protest at the informal or ARB stage.

To make the financial picture concrete, here is a realistic illustration for a Hill Country home, not guaranteed, but representative of how the arithmetic works. Take a home appraised at a value the owner successfully argues is 8 percent too high:

A tax cut is not a one-year event. If your value is corrected and neighborhood values stay in line, that lower value applies every subsequent year until the district reappraises you again, so a 56,000 reduction can repeat year after year. This is why the protest is best treated as an annual habit rather than a one-time fix [1].

Property tax protest consultants are common and perfectly legitimate in Texas. They take your case, build the comparable-sales file, and handle the hearings for you, and they typically charge a contingency fee of roughly 25 to 50 percent of your first-year savings, meaning no fee at all if they do not win [8]. For a homeowner who would rather not spend the time, that trade is often worth it.

The tradeoff is transparent: you give up a cut of the savings, but you hand off the work and the know-how. If you are comfortable pulling a few comparable sales and sitting on a phone call, you can absolutely do it yourself and keep all of the savings. There is no right answer for everyone. Compare the fee percentage before signing, because it directly changes your net result [8].

One practical note for California relocators specifically: this is an unfamiliar muscle. In California you may never have protested in your life, because Prop 13 rarely gives you a reason. In Texas, expect to consider it most years. Building a relationship with a real estate agent who can pull your comparables, or with a tax consultant, is simply part of becoming a Texas homeowner, and it is a habit worth forming early [1][8].
