Best Texas Property Tax Protest Services in 2026 (Compared)
Last updated: April 16, 2026
Texas homeowners protest more property taxes than any other state. Over 2 million protests are filed annually, and roughly 70% result in a reduction. Texas appraisal districts mail Notices of Appraised Value between late March and mid-April, and the protest deadline is May 15 or 30 days after the notice is mailed, whichever is later. Texas uses the term "protest" rather than "appeal," and filing is done with your county appraisal district, not the county assessor. If you are looking for help with your protest, the services below compare on pricing, coverage, and what you actually receive. The average successful Texas protest reduces appraised value by 10-15%. On a $350,000 home at a 1.7% effective tax rate, a 10% reduction saves approximately $595 per year. With AppealDesk at $49 flat, you keep $546 in Year 1. With a 25% contingency service, you keep $446. The gap widens on larger reductions and compounds over years since Texas reappraises annually.

#1: AppealDesk - Best for Budget-Conscious Texas Homeowners
AppealDesk provides an AI-generated evidence packet with comparable sales from your county, assessment ratio verification (Texas uses 100% so the full market value is protested), Texas-specific filing instructions referencing Form 50-132, and a cover letter. You pay $49 once and keep 100% of whatever reduction you achieve. The filing guide is tailored to your specific Texas county, with the right CAD name (HCAD, DCAD, TCAD, BCAD, TAD, CCAD, and so on), the right online portal, and step-by-step instructions. Most Texans file in 10-15 minutes. Coverage spans every Texas county, including ones that larger contingency firms skip.

- +All 254 Texas counties covered, including rural counties

#3: Ownwell - Best for Zero-Effort Full-Service in Texas
Ownwell handles the entire Texas protest process for you: filing, informal hearings, and ARB proceedings. You sign up, provide your address, and they do everything else. Their contingency model means you pay nothing upfront and nothing if they do not achieve a reduction. They report an 88% success rate with average annual savings of $774 across their service area. The trade-off is the 25% cut. On a $3,000 annual reduction, Ownwell's fee is about $750.
Pros
- +Zero effort, they handle filing and all hearings

#4: NTPTS - Best for DFW Full-Service Protests
North Texas Property Tax Services specializes exclusively in the DFW metro area, covering Dallas, Tarrant, Collin, and Denton counties. Their 81 years of combined experience and deep relationships with local ARB panels make them a strong choice for DFW homeowners with properties valued at $250K+. They report over $100 million in annual reductions for clients and know the tendencies of individual DFW appraisers and ARB members.
Pros
- +Deep DFW-specific expertise with local ARB relationships

#5: Texas Protax - Best for Austin and Houston Homeowners
Texas Protax has operated since 1988 with offices in Austin and Houston. They provide full-service protest representation including automatic annual filing, informal hearing attendance, and ARB representation. Their team of 30+ employees includes former appraisal district staff and licensed appraisers. The 40% contingency is higher than most competitors, and their market value reduction fee ($2.50 per $1,000) can apply even without actual tax savings.
Pros

#6: PropertyTax.io - Alternative DIY Evidence Tool for Texas
PropertyTax.io provides Texas-focused evidence for self-filing, with live chat support during protest season. Their pricing is contingency-based rather than flat fee, which is unusual for a DIY product. On a $2,000 annual reduction, the capped 35% fee can exceed $49 by 10x. A reasonable option for Texans who prefer contingency pricing on a DIY approach, but AppealDesk provides better value with the same DIY model at a predictable $49 flat.
Pros
- +Texas-focused data and evidence
- +Live chat support during protest season
- +Contingency pricing means no cost if the protest fails
Cons
- –Texas only

- –No ARB representation

How to Choose the Right Service
Start with your Texas county. Texas has 254 counties, each with its own appraisal district and ARB, and not every service covers every county. AppealDesk and O'Connor work statewide. Ownwell covers most of Texas. NTPTS is DFW only. Texas Protax is Austin and Houston only. Then consider pricing. The break-even between flat-fee and contingency is roughly $196 in annual savings. Below that, contingency costs less because you pay nothing if the protest fails. Above it, flat-fee keeps more money in your pocket every year, and that compounds because Texas reappraises annually. On a $350,000 home with a typical 10% reduction, flat-fee saves you hundreds more per year than contingency. Next, consider your effort preference. Texas is one of the easiest states to protest in yourself. Most CADs offer online filing, Form 50-132 is straightforward, and the informal hearing is a conversation, not a courtroom. If you have comparable sales and can spend 15 minutes, DIY is very viable, and AppealDesk bridges the gap with professional evidence for $49. Full-service firms like O'Connor, Ownwell, NTPTS, and Texas Protax charge more but eliminate all effort. Finally, consider your property. Standard residential overvaluation works well with any service on this list. Commercial properties, assessment methodology disputes, or multi-year corrections may benefit from O'Connor or NTPTS's institutional expertise.
