If a Notice of Appraised Value showed up in your mailbox this spring and the number made you sit down, you’re not alone. The envelope lands, you do the math, and something in your chest tightens. Travis County has been burning homeowners with aggressive appraisals for years, and 2026 is delivering another round of unwelcome surprises across South Congress, East Austin, and South Austin’s working neighborhoods.
Texas law gives every property owner an explicit right to challenge that number. The process doesn’t require a lawyer. And if you know where to click on the Travis CAD portal, you can file a formal protest in under 30 minutes.
This guide walks through every stage — from checking your exemption status before you do anything else, to filing online, to sitting across from a Travis CAD appraiser at an informal hearing, to making your case before the Appraisal Review Board if it comes to that. It’s written for Austin homeowners who want to understand the system well enough to use it.
The Deadline Is Probably Closer Than You Think
Texas Tax Code §41.44 sets the protest deadline at May 15 or 30 days after your Notice of Appraised Value was mailed, whichever is later. Travis CAD typically mails notices in April, which puts most homeowners at a mid-to-late May 2026 deadline.
Verify the exact 2026 protest deadline with Travis CAD. The portal URL, the direct filing link, and the Travis CAD main line (512-834-9317) should be confirmed and placed in a standalone callout box at the top of the published piece so readers who just want to file can stop here and do that.
The deadline applies equally to online and paper filings. No extension for digital submission. If you’re reading this in late April or early May, file now — not after the weekend. Miss it, and you lose your protest rights for the entire 2026 tax year with almost no recourse.
Step One: Check Your Exemptions Before You Touch the Protest Portal
This is the step most Austin homeowners skip. Don’t.
Before you open the protest workflow on travisCAD.org, pull up your property record on the same portal and confirm which exemptions are active. Here’s why it matters: the homestead exemption under Texas Tax Code §11.13 caps the increase in your taxable value at 10% per year regardless of what the market does. If Travis CAD raised your appraised value by 18% this year, your taxable value — the number your actual tax bill is calculated on — only increases by 10%. The protest may still be worth filing, but the math changes substantially once you understand that cap. For a full breakdown of how that cap interacts with other limits on your bill, see our coverage of how Austin’s three property tax caps work and what each one actually does to your bill.
More urgently: if you bought your home in the last few years and never filed for a homestead exemption, or if the exemption somehow fell off your record, fixing that omission could save you more than a successful protest ever would. It happens constantly — someone buys a house, life gets busy, the paperwork never quite happens. An unfiled homestead exemption also means you’ve been losing the 10% cap benefit for every year you didn’t have it on file. That’s real money you didn’t have to lose.
Pull your property record on the Travis CAD portal. Find the exemption column. If it’s blank or shows only a partial exemption, call Travis CAD at 512-834-9317 before you do anything else. Also check whether you qualify for an over-65 exemption or a disabled veteran exemption — both carry additional protections worth confirming regardless of your appraisal situation.
Only once you know exactly what exemptions are active and what your taxable value actually is should you decide whether a protest makes financial sense.
Filing Your Protest: The Portal Walkthrough
Reporter must verify the exact 2026 portal path, platform name, and any interface changes before publication. The Travis CAD portal has been updated in recent years, and the walkthrough below reflects the general workflow. Exact button labels and navigation paths must be confirmed against the live 2026 interface.
The portal is at travisCAD.org. The filing process works like this:
Locate your property record. Use the property search from the homepage — owner name, property address, or the 10-digit Travis CAD property ID printed on your Notice of Appraised Value. Confirm you’re looking at the right parcel. This matters if you own multiple properties or if your address has a unit designation.
Initiate the protest. Inside your property record, find the protest filing option. Verify the exact 2026 label — in prior years it’s appeared as “File a Protest” or through a dedicated iSettle or CSAP portal link. Click through and confirm the pre-populated ownership and address information before proceeding.
Select your grounds. This is the most consequential click in the process, and most homeowners make it without understanding what they’re selecting.
A market value protest means you’re arguing your property is worth less than Travis CAD’s appraised value. The burden is on you to show comparable sales that support a lower number. An unequal appraisal protest means you’re arguing your property is assessed at a higher ratio than similar nearby properties — even if the absolute value might be defensible on its own. This is a powerful option that almost nobody knows about, and frankly it’s the one most homeowners should be leading with. Texas law entitles you to appraisal that is fair relative to your neighbors, not merely accurate in isolation. Those are two different standards.
Select both grounds if you have any basis for either. No penalty for selecting both, and it preserves your ability to pursue whichever argument proves stronger when you see Travis CAD’s evidence.
Upload initial evidence if you have it. You’re not required to submit a complete evidence package at filing — the informal hearing is where evidence is exchanged. But uploading something at this stage signals preparation and can accelerate the process.
Schedule your informal hearing slot. The portal lets you pick a date and time for your meeting with a Travis CAD staff appraiser. Verify 2026 availability of phone, video, and in-person formats. Pick the earliest slot that gives you a week to ten days to pull your evidence. That’s usually enough for a standard residential case.
Prefer paper? Travis CAD’s office is at 850 E. Anderson Lane, Austin, TX 78752. Verify this address and 2026 office hours, which typically extend during protest season. Same hard deadline applies.
Which Austin Zip Codes Got Hit Hardest in 2026
Reporter must request 2026 neighborhood-level appraisal change data from Travis CAD’s public information office before publication. This is public record. The figures below are framing, not confirmed 2026 data — every percentage must be replaced with verified numbers.
Knowing where your neighborhood landed in this year’s appraisal cycle matters for more than just context. If Travis CAD increased values in your zip code by double digits and your property went up by a comparable or larger amount, you’ve got the foundation for an unequal appraisal argument — it becomes easier to find neighbors assessed at lower per-square-foot ratios. Our reporting on where Austin home prices are rising and falling in 2026 provides useful neighborhood-level context as you build that case, and it’s part of our broader legal and finance coverage of Austin property owners’ rights and costs.
South Congress and Bouldin Creek homeowners in 78704 have absorbed some of the steepest increases in recent years, driven by commercial corridor pressure along South Congress Avenue and sustained buyer demand for the neighborhood’s bungalow stock. Land values in particular have moved in ways that appraisers struggle to track precisely at the parcel level. Values can shift significantly within a few streets, so homeowners here should pull comps specifically for their block rather than relying on zip-code-wide trends.
East Austin (78702) presents a different picture. A decade of rapid appreciation has also produced significant inconsistency in how individual parcels are assessed relative to one another — and that inconsistency is exactly what makes unequal appraisal arguments viable here. If your neighbor’s structurally similar bungalow on the next block is assessed at $85 per square foot less than yours, that gap is your protest case.
South Austin (78745) warrants particular attention because the households absorbing these increases are disproportionately working-class and moderate-income homeowners. A significant appraisal jump isn’t an abstraction here — it’s a real monthly number that tightens real budgets. The homestead cap helps, but for owners who’ve held their property for several years and are sitting on accumulated increases, the effect adds up badly. Homeowners here should prioritize the exemption check in Step One before anything else.
Historically volatile zip codes also worth monitoring: 78701 (downtown), 78703 (Tarrytown and Bryker Woods), and the 78757/78758 corridor along North Lamar and Crestview.
Evidence That Actually Moves the Needle
Generic Texas advice says “bring comps.” Here’s what that means in practice.
For a market value argument, you need recent sales of comparable properties — ideally within the last six to twelve months, within a mile or two of your place, with similar square footage, lot size, age, and condition. Travis CAD’s own sales database is on the portal and uses the same data their appraisers work from. The Austin Board of Realtors’ public-facing MLS data (ACTRIS) can supplement your search. A licensed appraisal is the gold standard if the numbers justify the cost, and it carries real weight at an ARB hearing.
Don’t overlook condition evidence. Photographs of foundation issues, roof wear, deferred maintenance, or structural problems — paired with contractor estimates or inspection reports — can support a value reduction that sales data alone won’t reach. A property with a leaking roof and original HVAC won’t command the same price as a turnkey comparable, even if square footage and location are identical. If you’ve been putting off repairs, that deferred maintenance is working in your favor here.
For an unequal appraisal argument, build a comp grid: a table showing comparable properties in your neighborhood with their Travis CAD assessed values and assessed value per square foot. If the median assessed value per square foot for ten nearby properties is materially lower than your own, that’s your case. You don’t have to prove your property is worth less. Only that you’re being assessed at a higher ratio than your neighbors — a different and often easier argument to make.
The 14-day evidence exchange rule is one of the most important procedural tools available and one of the least used. Under Texas Comptroller Rule 9.3044, Travis CAD must provide their complete evidence packet at least 14 days before your ARB hearing. Request it proactively and read it carefully. Look at which properties they used as comparables and check whether those properties are genuinely similar to yours — size, condition, location, sale date. If they’re not, flag that specifically. And if Travis CAD misses the 14-day deadline, you can request a continuance. Do it.
The Informal Hearing
Most first-time filers don’t realize there are two separate hearings. The informal hearing comes first — a one-on-one meeting with a Travis CAD staff appraiser who has authority to offer you a reduction on the spot. This is not the Appraisal Review Board. It’s the meeting you scheduled through the portal when you filed.
Verify 2026 format options before publication. In prior years Travis CAD has offered phone, video, and in-person informal hearings. Confirm what’s available this cycle.
Pull the settlement rate from Travis CAD’s 2025 annual report. Historically, the majority of protests in Travis County resolve at the informal stage — most homeowners who show up prepared never need to go to the ARB.
What actually happens: the appraiser pulls up your property record, reviews your evidence, and may show you their own sales data. They can offer a reduction, hold the value, or in rare cases increase it. The meeting is short. Be specific and lead with numbers. “Your comps show sales at $X per square foot; here are five sales within six months within one mile that average $Y” is considerably more productive than a general statement that you think the value is too high. Bring printed copies of your comparables. Don’t rely on a phone screen.
What not to do: don’t negotiate against yourself by offering a number without being asked. Don’t accept a settlement that doesn’t reflect what your evidence actually supports. Declining the informal offer carries no penalty. If the appraiser offers a reduction that’s smaller than what your evidence supports, decline and advance to the ARB. You lose nothing.
The ARB Hearing, If It Comes to That
Decline the informal offer and your case automatically advances to the Appraisal Review Board. The ARB is independent of Travis CAD — its members are appointed by the local administrative judge, not Travis CAD. That distinction matters when you’re sitting in front of them.
The format is quasi-judicial: Travis CAD presents their case, you present yours, the panel asks questions, and the board issues a binding written order. ARB hearings in Travis County typically begin in June and run through July. Confirm the 2026 schedule before publication.
Organize your evidence in a tabbed binder with copies for each panel member and the Travis CAD representative. A typical binder has a one-page summary of your argument up front, then your comparable sales grid or unequal appraisal comp grid, photographs, and any supporting documentation — appraisal report, contractor estimates, condition notes. The panel sees hundreds of cases per day. Clear, organized presentation isn’t a nicety; it’s how you get heard.
Use the 14-day evidence exchange offensively. If Travis CAD used comps that aren’t genuinely comparable, say so clearly. “Exhibit 3 is a property that sold in 2024 on a corner lot with a recent renovation; mine is a 1962 interior lot with original finishes” is the kind of specific rebuttal that lands with a panel. Vague objections don’t.
If the ARB rules against you, three options remain. Binding arbitration is available below certain value thresholds and is faster and cheaper than district court — verify current 2026 eligibility thresholds. District court appeal is available but typically requires an attorney and involves real costs. The State Office of Administrative Hearings (SOAH) offers an alternative to district court for qualifying owners. Most residential homeowners won’t need any of these. But the ladder exists.
Is the Math Worth It?
A worked example at Austin price points, using approximate figures. Verify 2026 adopted combined tax rates (city, county, AISD) before publication. The effective combined rate in Travis County has historically run around 1.8–2.2% for many residential properties, varying by location and subject to annual adjustment.
At a $550,000 appraised value with an effective rate of roughly 2.0%, your baseline annual tax bill is around $11,000. A 5% successful reduction saves about $550 per year. A 10% reduction saves about $1,100.
Here’s the part most people miss: the savings compound. Under the homestead cap, Travis CAD can’t raise your taxable value from the revised baseline by more than 10% per year. The year-one savings figure understates the multi-year benefit substantially. Over five years, that $550 annual savings accumulates to $2,750 before accounting for additional increases on the new lower baseline.
Contingency fee agents typically charge 25–40% of first-year savings. At $550 in savings, the agent’s cut is $137–$220. At $1,100, it’s $275–$440. Whether that trade is worth it comes down to your bandwidth and how much you enjoy a Saturday afternoon with a spreadsheet.
Should You Hire a Tax Agent?
Austin’s property tax protest industry is large and the contingency fee model — no upfront cost, agent keeps a percentage of first-year savings only if they win — makes it accessible. But the structure creates real trade-offs.
Firms handling thousands of accounts operate at scale. That can work in your favor: deep comparable data, relationships with Travis CAD appraisers, established informal hearing patterns. It can work against you if your individual case gets lost in the volume. At the informal hearing stage especially, high-volume firms may take a quick settlement that leaves money on the table for properties with more complex evidence. Your property is one of thousands to them. That’s not a criticism — it’s just the math, and you should factor it in.
An agent makes strong sense for high-value properties where the savings floor is high, for cases involving unusual property characteristics or significant condition issues, and honestly for homeowners who just don’t have the hours. Standard single-family homes in neighborhoods with abundant comparable sales are cases where self-representation is realistic — particularly if you’re willing to spend a few hours pulling sales data from the Travis CAD portal and your property’s story can be told with three to five clean comparables.
Before signing anything, verify the agent’s license through the Texas Department of Licensing and Regulation (TDLR). The license lookup is publicly searchable. Current licensure is a baseline requirement, not a bonus.
The Notice of Appraised Value arrived. The deadline is fixed. File first, then decide on representation — but don’t let the decision about representation delay the filing.
