Overview: Texas Property Tax Agent Performance Study
With property taxes rising across Texas, the choice of representation matters more than ever. To understand the real impact of hiring a professional, we analyzed data from the 2025 tax season, comparing results between the state's legacy tax firms and the modern approach of Ownwell, which combines local experts with differentiating technology.
The study details performance by county and property value ranges, revealing significant differences in success rates and average net savings (savings after typical agent fees of 40%). This indicates that not all tax protest companies deliver the same ROI for residential homeowners.
Data Source and Scope
The performance data presented below is derived from 2025 county appraisal district records. Unlike other comparisons that examine only a few select competitors, this study compares Ownwell’s 2025 results with the aggregate results of all third-party tax agents operating in each county.
To ensure accurate net savings calculations and to make this study applicable to the average homeowner, the comparison set is limited to residential properties under $2 million. For more information, see our full methodology section below.

Key County Takeaways:
- Entry-Level Impact: For homes valued $250k-$500k, Ownwell achieved a staggering 98% success rate compared to 83% for the market, while delivering nearly double the average net savings per successful protest ($418 vs. $244).

The performance gap in Denton County is among the widest in the 11 counties studied. Ownwell didn't just edge out the competition; it operated in a different league. While legacy agents saw success rates fluctuate wildly between value bands, Ownwell maintained exceptional success rates above 90% across nearly the entire market.
This reliability also meant that, whether for an entry-level home or a multi-million-dollar estate, Ownwell clients were statistically more likely to secure a reduction and retain larger refunds.

Methodology
Data Sources:
We analyzed 2025 property tax protest outcomes for residential properties valued at under $2 million in many of Texas's most populous counties.
All data was obtained via public information requests directly from the Appraisal Districts of Bexar, Brazoria, Collin, Dallas, Denton, Fort Bend, Galveston, Harris, Montgomery, Rockwall, and Tarrant counties.
The 'data as of date' is when Ownwell received the county's latest certified roll.
Comparison Scope:
"Ownwell": Represents all residential property protests filed by Ownwell in the 2025 tax year.
"The Market" (Traditional Firms): Agent fees are typically a 40% contingency fee in many markets. Although some traditional firms' fees may vary and include a minimum flat fee if no reduction is achieved, we're assuming no minimum fees for this analysis.
The reported market performance reflects the average results, accounting for typical tax agent fees in each county.
Fort Bend Disclaimer: Due to county data limitations in Fort Bend County, the "market" benchmark includes both agent-represented and self-represented (DIY) protests.
Key Metrics:
Average Net Savings (When Successful): The average amount of money a homeowner kept in their pocket per successful protest.
This is calculated as Average (Property Tax Savings - Estimated Fees) / When Successful.
Success Rate: The percentage of filed protests that resulted in a reduction. A higher success rate indicates a greater likelihood that the homeowner will receive savings.
Exclusions: To ensure statistical validity, we excluded market value bands with fewer than 10 properties from the detailed analysis.
Fees:
Percentage-based fees: Applied to competitors' contingency rate (typically 40% of first-year savings).
Why fees matter: Traditional percentage-based fees mean that higher tax savings can result in lower net savings for the homeowner. This study measures what actually ends up in your pocket — the only metric that matters.
