Best Texas Property Tax Protest Services in 2026 (Compared)
Last updated: September 9, 2026
Choose a Texas property tax protest service by the work you need: evidence to support your own filing, or an authorized representative to manage the protest. Compare the written fee agreement, property eligibility, county coverage, and hearing scope. The options below are an editorial comparison of service types, not a measured ranking of results. A lower appraised value does not necessarily produce the same percentage reduction in your tax bill; exemptions, appraisal limits, and tax rates affect the result.
Travis Bunn·Updated September 9, 2026Customers, In Their Own Words
As of August 2026, 42 percent of the 70 reviews on the Trustpilot profile for Ownwell are 1 star. See the live profile.
★☆☆☆☆
Ownwell was not worth it and lost me a ton of money
“They absolutely put no effort into properly protesting my property. I lost so much money because of them. The county over-valued my property by almost $400,000, and Ownwell didn’t even submit comps. … Just do it yourself.”
★☆☆☆☆
Very deceptive results
“Very deceptive results, claimed I would save $600 on my property taxes, the actual savings were $55. Plus, they charged their 25% fee on the $600 they claimed the saved me.”
★☆☆☆☆
Absolutely unacceptable
“Then I discovered that my appeal had been withdrawn. … One of the worst professional-service experiences I have ever had.”
And the reviews AppealDesk customers leave on the same platform:

Travis is truly an invaluable resource. Thank you, Travis!”
★★★★★

Fee Comparison: Flat Fee vs Contingency in Texas
AppealDesk charges $49 for evidence preparation; you review the packet, file the protest, and handle any hearing. Full-service firms charge for representation as well as research. Check each provider's current agreement for its fee, covered county, renewals, and cancellation terms.
Illustrative fee comparison, assuming the same $1,000 annual tax reduction: a $49 packet leaves $951 after that service fee; a 25% contingency fee leaves $750; a 40% fee leaves $600. These are fee scenarios, not expected outcomes. Hearing, filing, or other costs may apply, and different services do not guarantee the same result.
Choosing a Protest Service in Austin and Travis County
For a home assessed by Travis Central Appraisal District, use the protest instructions on your notice and the TCAD portal. Austin-area properties can fall in other counties, so confirm the appraisal district for your address.
The ordinary Texas protest deadline is May 15 or 30 days after the appraisal district mails the notice, whichever is later. That ordinary May 2026 window has passed for many homeowners; check your own notice and any applicable late-protest rules. Decide whether you want evidence for self-filing or an authorized agent to represent you.
Choosing a Protest Service in Harris County
Harris Central Appraisal District provides the notice and local protest instructions for Harris County property. Check the deadline printed on your notice and whether the service you choose will file and attend hearings or provide evidence for you to use yourself.
AppealDesk's $49 residential evidence packet includes a filing guide. The homeowner remains responsible for filing on time and handling the local process. A full-service representative may suit an owner who wants that work handled for them; confirm scope and fees in the agreement before enrolling.
Sources and Fee Terms
Provider descriptions and published fee examples were reviewed September 9, 2026. Use the current agreement for your address; a listed fee is not a personalized quote. The Texas Comptroller explains the protest process and options after an appraisal review board decision.
How to Choose the Right Service
First decide whether you will manage the filing and hearing or want representation. Confirm the appraisal district and deadline on your notice, then check each provider's eligibility and agreement. Compare the fee calculation, owner responsibilities, hearing scope, renewals, and cancellation terms. Do not assume different services produce the same result or that a reduction carries forward unchanged in later years. Ask a qualified adviser about complex ownership, legal, or post-ARB issues.
