Every April, Travis Central Appraisal District mails an appraisal notice to every property owner in Travis County. Every year, hundreds of thousands of Austin metro homeowners either ignore the notice, or protest without evidence, or hire a contingency-fee service without understanding whether it makes sense for their specific case. This page walks through what actually works. It covers the mechanics of a Travis County protest in 2026, the four homeowner protections most property owners never fully use, the three protest paths, an honest comparison of DIY versus Ownwell or ProperTax versus an attorney, and the free CMA I run for any Travis County homeowner who wants a real answer on whether their TCAD value is defensible.
What TCAD does and how they get it wrong
TCAD is a Texas appraisal district responsible for setting the taxable value of every property in Travis County each year. They use mass-appraisal methods that model neighborhood-wide value patterns rather than individual property specifics, which is efficient at scale but produces predictable errors. Common ones I see on Travis County residential appraisals:
- Sales-comp method missing the actual comparable sales. TCAD often anchors on aspirational listing prices or older sales rather than what actually closed in your neighborhood in the last twelve months.
- Neighborhood-wide increases applied uniformly. A block that appreciated 8 percent gets a 15 percent value increase because the broader zip code did.
- Condition assumptions from the last inspection or aerial photo. A house that has since had foundation issues, dated systems, or storm damage still shows in TCAD's records at a healthier condition.
- Unequal appraisal across similar homes. The identical floor plan two doors down is assessed $80,000 lower because of when the last mass-appraisal pass touched it.
Any of these is a legitimate basis for protest. The Texas Property Tax Code explicitly allows protests on both market value grounds and equal appraisal grounds, and the equal appraisal argument is often the strongest one available in Travis County because TCAD's mass-appraisal method produces so much variance across similar homes.
The four homeowner protections that beat any protest
$100,000 school-district homestead exemption
Any Texas homeowner whose Travis County property is their primary residence qualifies. Application is a one-time filing with TCAD (no annual renewal needed once granted). Reduces the school-district taxable value by $100,000, which on typical Austin ISD tax rates is roughly $1,000 to $1,300 of annual savings. City, county, ACC, and other taxing units carry their own smaller homestead exemptions (typically $5K-$10K each). If you own a Travis County home and are not currently homesteaded, filing the exemption is worth more than any protest.
Homestead value cap on annual appraisal increases
Texas law caps the annual increase in a homesteaded property's appraised value at 10 percent plus the value of any new improvements. Once you have owned and homesteaded a property for a few years, the capped value can be dramatically below the market appraisal, and you are taxed on the capped value. This is why long-time Austin homeowners with a 1990s or 2000s purchase are often paying tax on half their home's actual market value. The cap only applies to homesteaded primary residences, not to investment properties.
School-district tax freeze plus additional exemption
Homeowners age 65 or older, or disabled, who own and occupy their primary residence in Travis County, qualify for an over-65 or disabled homestead exemption plus a tax ceiling on the school-district portion. The school district tax bill freezes at the year the exemption is granted and cannot rise regardless of future appraisal increases. This is one of the strongest homeowner tax protections in Texas. If you or a family member is 65+ and not yet filed, this single step is worth more than any protest.
Full or partial school-district exemption based on disability rating
Texas disabled veterans qualify for property tax exemptions on a sliding scale based on VA disability rating, with 100 percent disabled veterans receiving a complete homestead exemption on the school-district portion. Surviving spouses of qualifying veterans often inherit the exemption. Check the current TCAD disabled veteran exemption schedule and file with proof of your VA rating.
Every year I meet a Travis County homeowner planning a full-scale protest who has not yet filed a homestead exemption. The exemption almost always saves more than the protest would. File the exemptions first, then protest.
The three protest paths in order
Informal hearing
Meet by phone, video, or in person with a TCAD appraiser. Present comparable sales, unequal appraisal comps, and any condition evidence. Negotiate a settlement value. Roughly half of protests settle here. If you accept a settlement, the process is done for the year.
Formal ARB hearing
Evidentiary hearing before a three-member panel of TCAD-appointed Appraisal Review Board members. More formal than the informal, evidence is submitted in advance. If the ARB order is unfavorable, you have 60 days to file judicial appeal.
Judicial appeal
Lawsuit in Travis County district court challenging the ARB order. Requires a property tax attorney and meaningful dollar stakes to make the cost work. Rarely justified below $2M residential value unless the case is clean and the potential reduction is large.
DIY vs Ownwell vs attorney: the honest comparison
The honest read on contingency-fee services (Ownwell, ProperTax, and the local Texas equivalents): they take 30 to 50 percent of your first-year savings. On a modest reduction, that fee is meaningful. On a large reduction, especially for higher-value or investment property where the evidence work is substantial, they earn their fee cleanly. For a straightforward primary-residence protest under $1M with obvious comps, a well-prepared DIY protest gets essentially the same result at zero cost.
The evidence packet that actually wins
What a TCAD appraiser or ARB panel actually responds to is data, not emotion. The evidence packet that consistently gets reductions on Travis County residential protests looks like this:
- 5 to 10 recent comparable sales. Actual closed sales within 12 months, within 0.5 miles, similar square footage, similar age, similar features. Adjusted for meaningful differences (pool, updated kitchen, extra bathroom). Below your TCAD appraised value.
- 5 to 10 unequal-appraisal comps. Similar homes in the same neighborhood with lower TCAD appraised values. This is often stronger than the sales-comp argument because it does not require TCAD to reject market-value logic, only to acknowledge that similar homes should carry similar values.
- Condition documentation. Photos and quotes for any needed repairs (foundation, roof, HVAC, plumbing, electrical). Contractor estimates carry more weight than homeowner assertions.
- The market value calculation. A clear one-page summary showing the adjusted comp values, the median, and your proposed value. Make it easy for the appraiser to say yes.
This is the packet a good realtor or property tax consultant can prepare for you in a couple of hours. It is also the packet a determined homeowner can prepare themselves using TCAD's own public records plus a real estate agent friend's help with comparable sales.
How the free CMA works and why it matters
The single most useful thing a Travis County homeowner can do before deciding whether to protest is find out whether their TCAD appraisal is actually defensible. That is a comparative market analysis (CMA) question, not a tax question, and running a CMA is what I do for a living.
What I do for any Travis County homeowner who requests it: pull 5 to 10 relevant comparable sales in your specific neighborhood, run adjusted values, compare against your TCAD appraised value, and tell you honestly whether the appraisal looks over-market, at-market, or defensible. If the CMA shows you are over-assessed, I hand you the comps packet and you have your evidence. If the CMA shows the appraisal is defensible, I tell you that and save you a wasted Saturday. The CMA is free, non-obligation, and does not require you to list your home or engage me as your agent. It is the honest starting point for any real protest decision.
Bottom line
Property tax protest in Travis County works when the property is actually over-assessed, when the exemption stack is fully claimed, and when the evidence packet is clean. The order matters. File the homestead and any age or disability exemptions first, because those beat the protest almost every time. Then run a CMA to see whether the value is defensible. Then decide whether to protest DIY, hire Ownwell or ProperTax, or engage an attorney based on the specific property and the potential savings.
If you want the free CMA to check your TCAD value, use the primary form below and I will run comps and send you a written summary within 2 business days. If you want annual deadline reminders and quick homeowner-tax updates by email (no sales pitch, just the deadlines and rules changes), use the secondary form.
