Austin Real Estate Tax Protest: How to Fight Your Travis County Appraisal and Win
Why Travis County appraisals run high (and why protesting works)
The Travis Central Appraisal District (TCAD) is required by Texas law to value every property at 100% of market value as of January 1 each year. That sounds simple. In practice, TCAD values roughly 460,000 parcels using mass appraisal models that pull comparable sales from neighborhood clusters and apply adjustments for square footage, lot size, year built, and condition. Mass appraisal is a blunt instrument. It works well in tract subdivisions where every house is similar. It works poorly in Austin, where you can have a 1940s bungalow next to a 2023 modern build, and both get pulled into the same comp set.
The systemic bias runs in one direction. TCAD does not have someone walking through your kitchen to confirm the appraisal model’s assumptions. If the model assumes your roof was replaced in 2019 because the permits say so, and you actually still have the original 1998 shingles curling at the edges, the appraisal doesn’t know. Models also struggle to account for street-specific factors: a busy arterial road behind your fence, an industrial zoned parcel two doors down, foundation issues common to your subdivision. We see appraisals come in 5% to 15% above defensible market value in a typical year, and during the 2021-2022 Austin boom, the gap was often wider than that.
Protests work because the burden of proof at the Appraisal Review Board hearing is fairly even. You bring evidence, TCAD brings evidence, and a three-person panel of citizen volunteers decides. According to TCAD’s published statistics, more than half of formally protested properties get some reduction. The reductions are not usually dramatic — a 5% to 8% adjustment is more common than a 30% slash — but on a $900,000 Austin home, an 8% reduction is $72,000 of taxable value, which translates to about $1,400 saved annually at a 2% effective rate.
The 10% homestead cap and why it matters more than the appraised value
If your Austin home is your primary residence and you’ve filed a homestead exemption with TCAD, Texas Property Tax Code §23.23 caps the annual increase in your assessed value at 10%, regardless of what the market value does. This is the most underappreciated feature of Texas property tax. A homestead-protected house can have a market value of $1.2 million while the assessed value — the number you actually pay tax on — sits at $700,000, because the cap has compounded slowly over years while the market sprinted ahead.
Here is where strategy matters. If your homestead cap is well below market value, the protest decision changes. Lowering your market value by $50,000 on the appraisal notice doesn’t reduce your tax bill at all if your assessed value is already $300,000 lower than market. The cap is the binding constraint. But protesting still has a long-term benefit: lower market values today produce smaller compounded increases over the next decade. A $50,000 reduction now might not save you a dollar this year, but it could save you $5,000 over the next five years as the cap creeps upward from a lower base.
For non-homestead properties — investment houses, second homes, commercial real estate — there is no cap. The market value on the notice IS the assessed value, and every dollar of reduction flows straight to the tax bill. This is why Austin real estate investors and short-term rental owners protest more aggressively than primary-home owners. The math just works out differently. If you own an Airbnb in East Austin and TCAD pushes the value up by $100,000, that’s an immediate $2,000 hit to your annual operating expenses with no cap to dampen it.
Filing Form 50-132: the only deadline that matters
Form 50-132, the Notice of Protest, is the gatekeeper. Without it filed by the deadline, you have no protest, full stop. The deadline in Travis County is May 15 or 30 days after your appraisal notice was mailed, whichever is later. TCAD typically mails notices in early to mid-April, which means the practical deadline is mid-May for most properties. Miss it and you wait a full year for another shot.
The form itself is two pages and asks for basic identification: your name, the property address, the TCAD account number printed on your appraisal notice, and a checkbox indicating the grounds for protest. Check both boxes — market value too high AND unequal appraisal. There is no penalty for asserting both arguments, and you want to preserve every line of attack you might use at the hearing. You can file online through TCAD’s eFile portal, by mail, or in person at the TCAD office on Airport Boulevard.
We tell clients to file Form 50-132 the day they receive the notice, not the day before the deadline. Filing early gets you an earlier ARB hearing date, which matters because hearing slots fill up fast. A May hearing date gives you time to gather evidence and re-strategize if it goes badly. A late-July hearing means you’re cramming the week before, and any informal settlement offer from TCAD comes too late to help. Also, the appraiser assigned to your case has a smaller caseload in May than in July, which sometimes translates to a more reasonable informal review.
The equity argument vs the market value argument
Texas law gives you two independent grounds to protest, and they require completely different evidence. The market value argument says: my house is worth less than what TCAD says it’s worth, here are recent comparable sales to prove it. The unequal appraisal argument — the equity argument — says: even if TCAD’s value is technically correct, similar properties in my neighborhood are appraised at a lower percentage of market value, and uniformity is constitutionally required.
The equity argument is often stronger than people realize, especially in established Austin neighborhoods where TCAD’s mass appraisal has produced uneven results. If five houses on your street that are roughly comparable to yours are appraised at $650, $670, $680, $690, and $720 per square foot, and yours is appraised at $810 per square foot, the equity argument is a slam dunk regardless of what the recent market sales say. The median of the five comparables is $680, and Texas Property Tax Code §41.43(b)(3) entitles you to be appraised at no more than the median of a reasonable number of appropriately adjusted comparables.
The market value argument requires recent arm’s length sales, ideally from the six months before January 1 of the tax year. In a flat or declining Austin market, this is gold. In a rising market, it’s harder, because the most recent sales push the comp values up. We’ve had clients win equity arguments after losing market value arguments at the same hearing. The ARB panel applies whichever argument produces the lower value, so bringing both gives you two ways to win and only one way to lose.
Building the evidence packet that actually wins
An ARB panel sees dozens of protests in a day. They are tired, they have limited time, and they make decisions based on whichever side presents a cleaner, more organized argument. The single biggest mistake homeowners make is showing up with a sob story instead of a spreadsheet. Property tax appraisal is not about whether you can afford the bill. It’s about whether the number is correct. Bring documents, not feelings.
For the market value argument, pull comparable sales from the Multiple Listing Service if you have access, or from TCAD’s own sales database (available on the TCAD website). Focus on sales within your immediate neighborhood, similar in age, square footage, lot size, and condition. Three to five strong comparables beats ten weak ones. Adjust for known differences — if your comp has a pool and yours doesn’t, subtract roughly $40,000 to $60,000 for the pool value. Print photos of your home showing any conditions that would reduce value: outdated kitchen, original bathrooms, foundation cracks, deferred maintenance.
For the equity argument, pull TCAD’s appraised values for at least five comparable properties in your area and calculate the per-square-foot appraised value for each. Build a table showing your property compared to the median. If your number is higher than the median, you have a case. We’ve seen homeowners walk into hearings with a single sheet of paper showing this calculation and walk out with a $75,000 reduction. The cleaner the math, the easier the panel’s job, and the more likely they side with you.
The ARB hearing: what to expect and how to behave
ARB hearings in Travis County happen between May and July, typically run 15 to 30 minutes each, and are held at the TCAD office. Three panel members — civilians appointed by the local administrative judge — sit across the table. A TCAD staff appraiser presents the district’s case. You present yours. Then the panel asks questions, deliberates briefly, and announces a decision.
Show up early. Dress like you’d dress for a small claims court appearance — business casual is the norm. Bring three printed copies of your evidence packet, one for each panel member. Stay polite even when the TCAD appraiser says something you think is wrong. Panels read body language and tone, and a homeowner who comes off as reasonable and prepared wins more often than one who comes off as combative. Address the panel members, not the TCAD appraiser, when you speak. They are your audience.
Most ARB hearings now offer an informal review before the formal hearing. This is a closed-door conversation between you and the TCAD appraiser, usually held the same day or earlier. Many cases settle at the informal stage, and the settlement is often better than what you’d get at the formal hearing because the appraiser has discretion to lower the value without going through a panel decision. Take the informal review seriously, present your evidence cleanly, and accept reasonable offers. A 6% reduction in informal review is often better than gambling on an 8% reduction at the formal hearing, where the panel could just as easily reduce by 2% or nothing at all.
When to hire a property tax consultant (and when not to)
Texas has a thriving industry of property tax consultants who handle protests on a contingency basis. They typically take 30% to 50% of the first-year tax savings, and they handle everything from the Form 50-132 filing through the ARB hearing. For most Austin homeowners with primary residences worth under $1 million, the math on hiring a consultant is mediocre. A typical 5% to 8% reduction on a $700,000 homestead-capped home might save $400 to $600 in actual tax dollars, of which the consultant takes half. You’d have come out ahead doing it yourself.
For higher-value properties, investment real estate without homestead protection, and commercial buildings, the calculus flips. A consultant who specializes in Travis County, knows the ARB panel members, and has access to a database of recent comparable sales is worth the contingency fee. They are doing the work full-time, they have relationships with TCAD staff, and they can credibly threaten judicial appeal if the informal settlement is unreasonable. We’ve seen consultants get reductions on commercial properties that would have been impossible for the owner to achieve alone.
The middle ground is where The Reed Corporation often sits. For clients who own a primary residence plus one or two rental properties, we help structure the protest evidence, calculate the equity argument from TCAD data, and coach through the hearing without taking a contingency cut. The savings stay with the client. For commercial portfolios or single-property values above $2 million, we typically refer to a specialized Travis County property tax consultant we’ve worked with before. The right answer depends on the property, not on a blanket rule.
After the hearing: settlement, judicial appeal, and the next year
If the ARB panel agrees with your number, you receive an Order Determining Protest within a few weeks. The new value flows through to your tax bill, and you pay the lower amount when bills come out in October. If the panel rules against you or gives you a smaller reduction than you wanted, you have 60 days to appeal to district court under Texas Property Tax Code §42.21 or to seek binding arbitration through the Texas Comptroller’s office for properties valued at $5 million or less.
District court appeals are expensive. Filing fees, attorney costs, and the need to present expert appraiser testimony usually mean the math only works for properties where the disputed value is in the hundreds of thousands of dollars. Binding arbitration is much cheaper — the filing fee is $500 for residential properties, you don’t need an attorney, and the arbitrator’s decision is final. We’ve seen homeowners win at arbitration after losing at ARB, often because the arbitrator is a real estate professional who actually understands market value rather than a citizen volunteer.
Regardless of how this year’s protest turns out, file again next year. TCAD’s appraisal model resets each January 1, and the previous year’s reduction does not carry forward as a precedent. If you won a 7% reduction this year, the same model will likely overshoot again next year, and you’ll need to fight the same fight. Build a file folder — physical or digital — with your evidence packets, sales comparables, and ARB orders. The work compounds. By year three, you have a strong baseline and the protest takes a fraction of the time.

Frequently Asked Questions
When should I protest my Travis County appraisal versus accepting it?
The default answer is to protest every year, even when the increase looks reasonable, because TCAD’s mass appraisal model has no human reviewing your specific property and the cost of protesting is essentially zero if you do it yourself. The cost of NOT protesting is locked in for a full year — you cannot retroactively fix an appraisal that became final on the deadline. The asymmetry of outcomes (upside reduction, no downside risk except your time) makes protesting the rational default.
The exception is when your homestead cap has compressed your assessed value far below market value, and the appraised value on the notice doesn’t change your tax bill in any meaningful way. If your house has a $1.4 million market value and a $650,000 assessed value because of compounding 10% caps, lowering the market value to $1.3 million doesn’t move your tax bill at all this year. The cap is binding. In this scenario, the case for protesting weakens, but doesn’t disappear — future years’ compounded increases will start from the lower base.
The common mistake we see is homeowners who accept the appraisal because the increase looks small in percentage terms. A 4% increase on an Austin home is roughly $25,000 to $40,000 of additional appraised value, which translates to $500 to $800 in additional tax per year. Over a decade, that single accepted increase becomes $5,000 to $8,000 in cumulative additional taxes paid, all because the homeowner thought 4% sounded reasonable. Percentages obscure dollar amounts, and at Austin home values, percentages matter less than absolute changes.
Real-world example: a client in the 78704 zip code received a notice showing market value increased from $780,000 to $895,000 between 2024 and 2025. The 14.7% increase looked aggressive but not outrageous. We pulled five neighborhood comparables sold in late 2024 ranging from $740,000 to $830,000, with a median of $785,000. The TCAD comp set excluded one foreclosure sale that anchored the lower end of the range. At the ARB hearing, the panel adjusted the market value to $810,000, a $85,000 reduction. The client’s homestead cap had room because the prior assessed value was $720,000, so the reduction flowed partially to the tax bill: $1,700 in first-year savings.
Documentation needed before deciding: pull your TCAD appraisal notice, check both the market value and the assessed value lines, confirm your homestead exemption is on file, and look at the prior year’s values to see the percentage change. If the assessed value is significantly below market value and didn’t increase by the full 10%, the cap has slack and protest savings will be smaller. If the assessed value tracks the market value closely, every dollar of reduction flows through.
Audit considerations: filing a protest does not trigger any other type of audit or scrutiny. TCAD has no authority to investigate income tax matters, IRS filings, or anything other than the parcel-specific valuation. Some homeowners worry that a protest invites TCAD to look harder at their property in the following year. There is no evidence this happens systematically. The mass appraisal model treats your property the same way it treats every other property, protest history despite.
What The Reed Corporation does: for clients with multiple Texas properties or values above $1.5 million, we run the analysis annually as part of our advisory work. We pull the appraisal notice, compare it against recent sales and equity comparables, and tell the client whether a protest is worth their time. For straightforward homestead cases under $1 million, we coach clients through the DIY process rather than charging for work they can do themselves in a few hours. The goal is the client paying the right tax, not us billing for unnecessary services.
One more consideration that gets overlooked: if you plan to sell your Austin home within the next year or two, the appraisal value on file can affect buyer perception. A high TCAD value signals to buyers that the property tax bill will be substantial and may price out some otherwise-interested purchasers. A protested-down value reduces that friction. We’ve had clients protest aggressively in the year before listing because the lower tax bill made the home easier to market.
If you decide not to protest a particular year, document your reasoning in writing (a note to yourself in your tax file) so you can revisit it next year with context. TCAD values reset every January 1, and a year you skipped becomes irrelevant. The next year stands on its own facts. Don’t beat yourself up over a year you didn’t fight. Just fight the next one.
What evidence do I need for an Austin real estate tax protest?
Three categories of evidence carry weight at a Travis County ARB hearing: comparable sales data, equity comparables showing other properties appraised at lower per-square-foot values, and condition-based evidence showing your property has issues that reduce value. The best protests bring some of each. The worst protests bring only feelings about the unfairness of the system, which the panel cannot legally consider.
Comparable sales should be from the 12 months preceding January 1 of the tax year, with strong preference for the six months immediately before. Pull sales from your immediate subdivision or neighborhood, ideally within a quarter-mile radius. Match for square footage within 15%, age within 10 years, and bedroom/bathroom count. Avoid using foreclosure or short sale comps unless they make up a substantial portion of your neighborhood’s activity, because TCAD will argue they don’t represent arm’s length transactions.
Equity comparables come from TCAD’s own database. Go to the TCAD website, search for properties on your street and surrounding streets, and record their appraised values. Calculate price per square foot for each. Build a table sorted by per-square-foot value, identify the median, and compare your property to that median. If you are above the median by more than 10%, you have a meaningful equity argument. Texas Property Tax Code §41.43(b)(3) explicitly entitles you to be appraised at no more than the median of appropriately adjusted comparable properties.
Condition evidence is photographs and contractor estimates. If your kitchen is original from 1992, photograph it. If your roof needs replacement, get a contractor estimate and bring it. If you have foundation cracks, structural issues, or active water damage, document all of it. TCAD’s mass appraisal model assumes average condition for the age of the home. Below-average condition is grounds for adjustment. Above-average condition isn’t a problem because TCAD won’t argue it without their own evidence.
Common mistakes: bringing too many comps and overwhelming the panel, using comps that are too far away or too dissimilar, failing to adjust for known differences like pool or garage. A clean five-comp packet with adjustments beats a 20-comp packet without adjustments every time. Also, do not bring Zillow estimates or Redfin estimates. Texas ARB panels do not consider AVM-generated values as evidence. They want actual sale prices from actual transactions, sourced from MLS or county deed records.
Real-world example: a client in Mueller protested a $1.1 million appraisal in 2024. We pulled four 2023 sales from within 0.3 miles, ranging from $945,000 to $1,015,000. We pulled six equity comparables from the same neighborhood, showing TCAD per-square-foot appraised values ranging from $385 to $445, with a median of $410. The client’s property was appraised at $478 per square foot. The market value argument supported a value of $1.0 million. The equity argument supported a value of $980,000. The ARB panel applied the lower (equity) value and reduced the appraisal to $980,000, saving $2,400 in annual taxes.
Documentation to bring on the day of the hearing: three printed copies of your full evidence packet (one for each panel member), a one-page summary at the front showing your proposed value and the basis, and photo identification. Some panels also accept digital evidence on a tablet or laptop, but printed packets always work. Bring everything in a folder, organized, with tabs if you have multiple categories of evidence. The visual cleanliness signals seriousness.
Audit considerations: ARB proceedings are administrative hearings, not legal proceedings in the strict sense. There is no formal discovery, no sworn testimony in most cases, and no transcript unless you specifically request one. Evidence rules are loose. You can introduce documents without authentication, refer to information you’ve read online, and present arguments that wouldn’t pass muster in a courtroom. This works in your favor when you’re prepared and against you when you’re not, because the TCAD appraiser is also operating under loose rules.
Where The Reed Corporation adds value: we have a template evidence packet we share with clients that organizes the four required sections (proposed value summary, comparable sales table, equity comparables table, condition photos) in the format Travis County ARB panels are used to seeing. We can also pull the underlying data — TCAD appraisal values, recent sales, square footage adjustments — in 15 minutes using subscriptions and tools the average homeowner doesn’t have. For clients we work with annually, the second-year evidence packet is mostly a refresh of the first-year work.
If you’re DIY-ing the evidence gathering, allocate four to six hours total: two hours pulling sales and equity data, one hour photographing your property and its condition issues, one hour building the spreadsheet and writing the summary, and one to two hours preparing your verbal presentation. That sounds like a lot, but spread over two weekends it’s nothing compared to the multi-thousand-dollar swing in your tax bill that turns on whether the panel believes your number.
What’s the difference between the equity argument and the market value argument at ARB?
The market value argument says TCAD’s appraised value is higher than what your property would actually sell for on the open market. You prove it with recent arm’s length sales of comparable properties, adjusted for differences. The equity argument says even if TCAD’s value is defensible against the market, similar properties in your neighborhood are appraised at a lower per-square-foot value, and the Texas Constitution requires uniform appraisal. The two arguments rest on completely different legal foundations and require different evidence.
The market value argument is grounded in Texas Property Tax Code §23.01, which requires appraisal at 100% of market value. If your house wouldn’t sell for $900,000 in an arm’s length transaction, TCAD cannot legally appraise it at $900,000. The argument is straightforward and intuitive. It also has weaknesses: in a rising market, recent sales push values up, and TCAD has access to the same sales data you do. The market value argument tends to work well in stable or declining markets and struggles in hot ones.
The equity argument is grounded in Texas Property Tax Code §41.43(b)(3), which entitles a property owner to be appraised at no more than the median appraised value of a reasonable number of appropriately adjusted comparable properties. Notice the key word: appraised value, not market value. The equity argument is comparing your TCAD appraisal to TCAD appraisals of similar properties. If TCAD over-appraised your neighbor’s house too, that doesn’t help you — the median sets the ceiling.
The equity argument is often stronger than the market value argument in Austin’s hot neighborhoods. TCAD’s mass appraisal model produces inconsistent results across neighborhoods. We frequently see five similar houses on the same street with per-square-foot appraised values ranging from $390 to $480, with no obvious reason for the spread. If your property is on the high end of that range, the equity argument is straightforward arithmetic: here are five comparables, here is the median, here is mine, please adjust me to the median.
Common mistake: choosing equity comparables that are too easy to dismiss. If your property is a renovated 1950s ranch and you choose equity comps that are tract houses from a 1990s subdivision two miles away, the TCAD appraiser will argue they aren’t comparable. Pick equity comps that are genuinely similar in age, size, lot, and condition, ideally from the same subdivision or immediate area. Five strong equity comps beat ten weak ones, and panels respond to obvious patterns over scattered data.
Real-world example: a client in Hyde Park had a 1925 Craftsman appraised at $980,000, which translated to $560 per square foot for a 1,750-square-foot home. We pulled six equity comparables from within a four-block radius, all 1915-1935 Craftsman-style homes between 1,600 and 1,950 square feet. Their TCAD appraised values ranged from $390 to $510 per square foot, with a median of $445. We argued the equity case at ARB. The panel reduced the client’s appraisal to $785,000, a $195,000 reduction, saving roughly $3,900 in annual taxes.
Documentation differences: the market value argument needs actual closed sales with verifiable transaction details (sale date, sale price, days on market, MLS number). The equity argument needs TCAD’s own published appraisal values, which are free to pull from the TCAD website. The equity argument is easier to research and harder to dispute because the underlying data is TCAD’s own work product. The market value argument is more familiar to most homeowners but harder to win because TCAD pre-runs the same comp analysis.
Bring both arguments to every hearing. Texas law allows ARB panels to apply whichever argument produces the lower value. There is no penalty for bringing two arguments and only one being convincing. We’ve had clients lose the market value argument completely and still win the equity argument, ending up with substantial reductions. Bringing only one argument is leaving a tool on the table. The TCAD appraiser is bringing every argument they have. You should do the same.
Audit considerations: equity arguments sometimes shift the focus from your individual property to broader neighborhood patterns. If TCAD has systematically over-appraised your neighborhood relative to others, your equity argument can succeed even when your specific market value defense is weak. Conversely, if your neighborhood has been carefully calibrated by TCAD, the equity argument may not show much spread. Pulling preliminary equity data before you commit to filing the protest tells you which argument deserves more attention.
What The Reed Corporation does for clients: we help structure both arguments and identify which one is likely to be stronger before you walk into the hearing. For properties under $1 million, we typically provide a one-page worksheet and let the client run the analysis themselves. For higher-value properties, we build the evidence packet directly and either attend the hearing with the client or coach them through the presentation. The equity argument is often the unsung hero of Travis County protests, and homeowners who only bring market value evidence are leaving money on the table.
How much does an Austin property tax protest typically save?
The typical successful Travis County protest produces a 5% to 10% reduction in appraised value, with a substantial range around that. The dollar savings depend on your tax rate (about 2% effective in most of Austin), the size of the reduction, and whether you have homestead cap protection that limits the flow-through to your tax bill. A 7% reduction on a $700,000 appraisal saves about $980 per year if the homestead cap doesn’t apply, less if it does.
The exception is properties that were significantly over-appraised, where reductions of 15% to 25% are achievable with strong evidence. We see this most often with unique properties (architecturally distinctive homes, properties with site-specific defects like flood plain location or foundation issues, homes adjacent to commercial or industrial zoning) and with properties caught in a TCAD mass appraisal model adjustment that swept the entire neighborhood too high. In bad TCAD years — 2022 was one — aggressive protests can produce reductions over 30%.
Common mistakes that depress savings: failing to file an equity argument alongside a market value argument, bringing weak comparable sales, accepting the first informal settlement offer without negotiating, and not preparing for the hearing seriously. Many protests that should have produced 10% reductions end up at 4% or 5% because the homeowner accepted a quick handshake deal at informal review. The TCAD appraiser is motivated to settle as many cases as possible quickly. You are motivated to get the right answer. Those motivations are not aligned.
Real-world example: a client owned a non-homestead investment property in Cherrywood appraised at $620,000 in 2024. We pulled eight comparables (four sales, four equity) and identified $545,000 as the defensible value. At informal review, the TCAD appraiser offered $580,000. We declined and went to formal ARB. The panel ruled $555,000, which produced a $1,300 annual tax savings. Had we accepted the informal offer, the savings would have been $800. The hour of additional negotiation produced $500 of additional annual savings, which compounds year after year because the lower value becomes the starting point for next year’s appraisal.
Documentation that drives larger reductions: third-party appraisals, professional contractor estimates for needed repairs, formal engineering reports on structural issues, and historical sales data showing a long-term price pattern. Most homeowners don’t bring third-party evidence to a residential protest because the cost (a full appraisal runs $500 to $700) often exceeds the marginal savings. For commercial properties or homes above $1.5 million, the cost-benefit shifts and a professional appraisal becomes worth ordering.
Audit considerations: large reductions in one year sometimes trigger closer attention from TCAD in the following year. Not formal scrutiny, but the appraiser may push back harder at the next protest, demanding more evidence. The way to manage this is to maintain the evidence over multiple years. If you won a 15% reduction in 2024 based on documented foundation issues, those issues still exist in 2025 unless they’ve been fixed. Keep the photos, keep the contractor estimates, and bring them back next year. Continuity of evidence builds credibility.
Average savings across all Travis County protests, including the ones that produce no reduction at all, comes out to roughly 4% to 6% of appraised value when measured against the original notice. This is partly because many protests are filed without follow-through, and unattended protests typically result in no change. The protests that DO get worked through to a hearing produce average reductions closer to 8% to 12%. The difference between filing a protest and actually working a protest is substantial.
What The Reed Corporation tracks: for our advisory clients, we maintain a property tax file that tracks each year’s protest, the evidence presented, the result, and the tax savings. Over a five-year period, the average Austin client we work with has saved between $4,000 and $18,000 in property taxes through protests, depending on property value and how aggressive their initial appraisals were. The compounding effect is real — lower appraised values today become the baseline that future years’ increases stack on top of.
If you’ve never protested before and your property has been on TCAD’s rolls for several years, your first protest year tends to produce the largest reduction because there’s accumulated drift to recover. Subsequent years produce smaller reductions because the gap between your appraisal and defensible market value is smaller. This is a feature, not a bug. The protest process is supposed to keep appraisals honest year over year. Once you’re in that rhythm, the savings stabilize at a lower but reliable level.
One realistic frame: think of protesting as an annual maintenance task that produces a return roughly equal to a few hours of your hourly rate. If you can save $1,200 in taxes for six hours of work, that’s $200 per hour, tax-free. Few activities available to a typical homeowner pay that well. The work is also satisfying in a way that other tax planning isn’t — you walk out of an ARB hearing with a specific dollar amount you saved, which feels different from the abstract benefits of most tax strategies.
Can I appeal an ARB decision and what are the next steps?
Yes. If the Travis County ARB rules against you or gives you a smaller reduction than you wanted, you have two appeal paths: district court litigation under Texas Property Tax Code §42.21, or binding arbitration through the Texas Comptroller’s office for properties valued at $5 million or less under §41A. You have 60 days from receiving the ARB’s Order Determining Protest to file either appeal. Miss the 60-day window and the ARB decision becomes final.
District court appeals are full lawsuits. You file a petition in Travis County district court, serve the appraisal district, conduct discovery, exchange expert reports, and either settle or go to trial. The court reviews the appraisal de novo, meaning it doesn’t defer to the ARB’s findings. This is the path for high-value commercial properties and very expensive homes where the disputed value is hundreds of thousands of dollars. Attorney costs typically run $10,000 to $30,000 for a residential case and substantially more for commercial. The math only works when the savings clearly exceed the costs.
Binding arbitration is the more practical appeal route for most residential properties. The filing fee is $500 for residential homestead properties valued at $500,000 or less, $500 for non-homestead residential at any value, and higher amounts for more expensive properties. The Comptroller’s office assigns an arbitrator from a list of qualified professionals (often appraisers, real estate brokers, or attorneys). The arbitrator reviews the evidence, may hold a hearing in person or by phone, and issues a decision within 120 days. The decision is final and binding on both you and TCAD.
Real-world example: a client owned a Westlake home that received a $1.3 million appraisal in 2024. At ARB, the panel reduced to $1.22 million, less than the $1.1 million we’d documented. We filed for binding arbitration with a $1,050 filing fee. The arbitrator (a retired commercial appraiser) reviewed our evidence packet and TCAD’s response, held a 45-minute phone hearing, and issued a decision setting the value at $1.13 million. Total annual tax savings versus the ARB decision: $1,800. Total cost to pursue: $1,050 filing fee. Net first-year benefit: $750, plus continuing savings in future years because the lower value became the baseline.
Common mistakes in the appeal process: missing the 60-day deadline (it’s strict, with no exceptions), failing to pay the arbitration filing fee on time, and reusing the same evidence packet from ARB without strengthening it. The arbitrator has access to your ARB evidence through TCAD’s submission, so simply repeating the same argument that lost at ARB rarely wins at arbitration. You need to either bring new evidence or present the existing evidence more compellingly. If you’re going to arbitration, treat it as a fresh case.
Documentation needed for appeal: the ARB Order Determining Protest, the original Notice of Protest, your evidence packet from the ARB hearing, any new evidence you’ve gathered since (recent sales, updated condition photos, third-party appraisals), and the filing fee. For arbitration, file the request directly with the Comptroller’s office using Form AP-219. For district court, file a petition through an attorney admitted to practice in Travis County.
Audit considerations: appeals don’t trigger any other type of audit or scrutiny. TCAD treats appeals as adversarial proceedings in the specific tax year disputed, with no spillover to other years or other matters. Some homeowners worry that appealing makes them a target for harsher treatment in the future. There is no evidence this happens. The appraisal district moves on to the next batch of properties and doesn’t carry grudges. The appeal is forgotten by January 1 of the next tax year, when the mass appraisal model runs fresh.
Where to find a third-party appraiser for arbitration evidence: licensed appraisers in Travis County who specialize in protest support can be found through the Texas Appraiser Licensing and Certification Board. Costs run $400 to $700 for a residential property and substantially more for commercial. A third-party appraisal carries weight at arbitration that homeowner-prepared evidence does not, because the arbitrator can take it as professional opinion rather than as advocacy from a property owner with obvious motivation.
What The Reed Corporation does: for clients who lose at ARB and have a defensible appeal case, we evaluate the math on district court versus arbitration. For most residential properties, arbitration is the right answer. We help prepare the filing, sharpen the evidence packet, and coach through the arbitration hearing. For commercial portfolios or high-value residential, we work with property tax attorneys we’ve used before for the district court option. The decision tree is straightforward: if the additional savings from winning at appeal exceed the cost of pursuing it, go forward. If not, accept the ARB decision and refile cleanly next year.
One observation that surprises clients: arbitrators are often more receptive to homeowner arguments than ARB panels, possibly because arbitrators are working real estate professionals who understand market dynamics in a way that citizen panel members don’t always. We’ve seen homeowners win at arbitration after losing at ARB on cases that should have been close calls in both forums. The arbitrator’s professional background changes the conversation. If your ARB hearing felt like the panel didn’t fully understand your evidence, arbitration deserves serious consideration.
