Searching for the best Texas property tax protest companies can produce a confusing mix of company-written rankings, ads, local firms, technology platforms, consultants, attorneys, and forum recommendations. This guide does not declare one company "best." Instead, it compares several providers that currently appear prominently in Texas search results and gives you a consistent framework for evaluating fees, licensing, evidence, hearing representation, renewal terms, and post-ARB options.
There is no single best company for every Texas property owner. The right choice depends on your property type, the amount at stake, the evidence required, how the firm charges, who will actually handle the protest, whether you want automatic annual filing, and what happens if the case reaches arbitration or court. Compare providers using the same checklist rather than choosing solely by brand size, advertised success rate, or the lowest headline fee.
No provider — including PropertyTaxes.Law — can guarantee a reduction before reviewing your specific property and evidence. Treat any advertised "success rate" or guaranteed-savings claim as a marketing figure to verify, not a promise about your outcome.
This is a buyer's guide, not a numerical ranking. We intentionally do not score companies by self-reported "success rate," total savings, number of customers, or online review count because those figures can use different definitions, property mixes, time periods, and denominators.
We reviewed established providers that appear prominently in current Texas search results for property tax protest company comparisons.
Fee and service descriptions come from the providers' own public websites, not third-party reviews or affiliate summaries.
Each provider is evaluated on pricing transparency, protest scope, property focus, hearing coverage, and what a buyer should verify.
We do not award PropertyTaxes.Law or any competitor a #1 ranking. Different owners need different service models.
The table below summarizes publicly stated information from several providers currently visible in the Texas search market. It is not a ranking or endorsement.
| Company | Publicly Stated Fee Model | Publicly Stated Protest Scope | What to Verify Before Hiring |
|---|---|---|---|
| O'Connor | Public site currently states no upfront/flat fee and a 50% contingency fee on current-year tax savings, calculated using the prior year's tax rate. | States that it files protests, prepares evidence, attends informal and ARB hearings, files binding arbitration, and coordinates judicial appeals when appropriate. | Confirm how "savings" are calculated, whether every post-ARB stage is included in your specific agreement, renewal terms (contract auto-renews until 30-day written cancellation), and who will handle your property. |
| Ownwell | Publicly states a 25% contingency fee on first-year Texas savings, with no upfront fee. (Higher tiers, such as 35%, apply to other states like California and Florida — not Texas.) | States that it manages filing, evidence, negotiations, and appeal-board hearings using technology plus local tax experts. | Confirm the fee still applies at 25% for your specific property type, whether the engagement auto-renews annually, post-ARB scope, and who appears at the hearing. |
| Resolute Property Tax Solutions | Resolute's own site states a standard rate of approximately 40%-50% of first-year savings, with no upfront fee, and notes some engagements "sometimes include a fixed fee." | Markets residential and commercial Texas protest services and emphasizes a team that includes former appraisal-district appraisers. | Request the exact percentage and whether a fixed-fee component applies to your property, confirm counties/property types covered, ARB scope, post-ARB representation, and automatic renewal terms. |
| Texas Protax | 40% of actual tax dollar savings, with a $50 minimum fee per parcel. A separate "market value reduction fee" (reported around $2.50 per $1,000 of market value reduction) may also apply, potentially even when it does not produce actual tax savings — confirm this directly. | Describes a full-service process covering informal negotiations, formal ARB hearings, and arbitration when necessary. Primarily serves Austin (Travis, Williamson, Hays) and Houston (Harris). | Confirm whether the market value reduction fee applies to your property and under what circumstances, service-area coverage for your county, arbitration costs, and whether litigation is outside the engagement. |
| Gill, Denson & Company | Current published pricing: 30% of tax savings for residential clients with 1-4 properties, dropping to 25% at 5 or more properties. Single-property residential clients may also be charged an upfront, non-refundable minimum fee applied toward the final invoice — confirm this before signing. | States that it handles filing, evidence, informal and ARB hearings, and reviews cases for binding arbitration or litigation, across all 254 Texas counties. | Confirm the tier that applies to your portfolio, the upfront minimum fee for single-property accounts, whether post-ARB work is included, and automatic annual renewal terms. |
| Texas Tax Protest | The current homepage/FAQ reviewed directs users to inquire about service cost rather than displaying one universal fee percentage. | States that it handles research, paperwork, evidence, and advocacy with Texas appraisal districts and offers statewide property tax protest services. | Ask for the exact fee, renewal terms, ARB representation details, post-ARB options, and whether additional charges apply at later stages. |
Public information checked and re-verified September 8, 2026, cross-referenced against each provider's own site plus independent third-party sources where available. Providers can change pricing, service areas, personnel, terms, and post-ARB offerings at any time. The signed engagement agreement controls your actual relationship with a provider.
A 25% fee and a 50% fee are not directly comparable unless both firms define "savings" the same way. Ask what tax rate, exemptions, baseline value, and tax year are used in the fee calculation — and whether any secondary fee (like a value-reduction fee) can apply independently of tax savings.
Verify whether the person performing compensated property tax consulting is registered with TDLR when required, or falls within a statutory exception such as an active Texas attorney or Texas CPA.
Ask whether your property will be handled by a named consultant, senior consultant, attorney, appraisal specialist, centralized team, or rotating staff.
Ask whether the firm reviews district evidence, condition issues, comparable sales, unequal appraisal, income data, cost data, property records, and owner-supplied documents when relevant.
Confirm whether formal ARB representation is included, who attends, and whether the company can explain the case strategy before the hearing.
Ask whether the provider handles or coordinates regular binding arbitration and whether district-court litigation requires a separate attorney engagement.
Some firms automatically protest every year. That can be convenient, but you should understand renewal, cancellation, notice deadlines, and any fees triggered after cancellation.
There is no single statewide fee model. The contract matters more than the marketing phrase "no win, no fee."
You pay a percentage of the savings defined in the agreement if the protest produces a qualifying reduction. Ask exactly how savings are calculated.
You pay a fixed amount for a defined scope regardless of the final reduction. This creates cost certainty but can be less attractive for low-value cases.
Some engagements can include a minimum charge, account fee, or other fixed component plus a success fee. Read the contract carefully.
A small number of firms charge a fee based on the dollar amount of market value reduction achieved, which can apply even if that reduction does not translate into actual tax savings for the year. This is different from a tax-savings contingency fee — ask which model applies.
Complex commercial, industrial, litigation, consulting, or portfolio work may use custom pricing rather than a standard residential contingency model.
Suppose a protest ultimately reduces the current-year tax bill by $1,000. A 25% success fee would be $250, a 40% fee would be $400, and a 50% fee would be $500 if each contract uses actual $1,000 tax savings as its fee base. But contracts can define savings differently, use a specified tax rate, treat exemptions differently, include a separate value-reduction fee, or include other charges.
Ask for a worked example before signing. Give the company a hypothetical starting value, final value, exemptions, and tax rate, and ask it to show the exact fee calculation under its contract — including whether any fee applies even if your actual tax bill does not go down.
The Texas Department of Licensing and Regulation regulates property tax consultants. TDLR states that people performing or supervising compensated property tax consulting services generally must be registered when the statutory requirements apply.
TDLR also recognizes important exceptions. An active Texas Bar attorney or a Texas registered CPA may practice as a property tax consultant without registering as a PTC. Certain Texas real-estate licensees or appraisers can also have limited exceptions for specified property types.
Search the individual in the TDLR Property Tax Consultant licensing resources when registration is required.
If the provider says an attorney is handling legal work, verify the attorney's Texas licensing/eligibility status rather than relying only on the company's marketing page.
Ask for the name and credential of the person who will actually present your protest, not just the name of a senior professional shown on the website.
Review TDLR disciplinary/enforcement resources when relevant and ask the provider to explain any licensing structure you do not understand.
A common mistake is assuming that a property tax consultant can handle only the informal protest while an attorney is required for every later stage. Texas rules are more nuanced.
| Stage / Issue | Property Owner | Authorized Consultant / Agent | Texas Attorney |
|---|---|---|---|
| File ordinary protest | Yes | Yes, when properly appointed/authorized | Yes |
| Informal conference | Yes | Yes, within authorized scope | Yes |
| ARB hearing | Yes | Yes, when properly appointed and legally authorized | Yes |
| Regular Binding Arbitration | Yes, if eligible | Agents may represent owners under the RBA process; online filing rules apply to represented owners | Yes |
| Legal advice | N/A | A nonlawyer should not provide legal advice beyond what law permits | Yes, within attorney-client representation |
| District-court representation | Self-representation rules depend on the owner/entity and circumstances | Nonlawyer consultant should not be assumed able to represent a client in court | Licensed attorney can provide court representation subject to the engagement and applicable rules |
This table is general educational guidance, not legal advice. Representation rights can depend on the owner, entity, proceeding, appointment, licensing, and specific facts.

| Factor | DIY | Hiring a Protest Company |
|---|---|---|
| Professional fee | No representation fee | Contingency, flat, minimum, value-based, hourly, or custom fee depending on contract |
| Your time | You handle filing, research, evidence, conferences and hearing preparation | Company typically handles much of the administrative and hearing work |
| Control | You control arguments, evidence and settlement decisions directly | Scope and communication depend on the engagement agreement and provider process |
| Evidence experience | Depends on your appraisal/property-tax knowledge | Can provide specialized experience, but quality and depth vary by firm and handler |
| Simple factual error | Often reasonable to handle yourself | Professional fee may not add enough value for a simple low-dollar correction |
| Complex commercial / portfolio | Can require significant analysis and administrative time | Professional representation may be more attractive where the amount at stake or complexity is higher |
| Post-ARB escalation | You must research the correct next remedy | Some firms handle or coordinate arbitration; court work may require separate attorney representation |
For the broader cost-benefit question, see Are Property Tax Protest Companies Worth It in Texas?.
What exactly is your fee? Ask for the percentage, minimum, flat fee, account fee, or other charge in writing.
How do you define "tax savings"? Ask which tax rate, exemptions, starting value and final value are used — and whether any fee applies based on value reduction alone, separate from tax savings.
Who will handle my property? Ask for the role and credential of the person responsible for the file and hearing.
Is the person a registered Texas property tax consultant, attorney, CPA, appraiser, or another type of agent?
Will you request and review the appraisal district's evidence? Do not assume every provider uses the same evidence-development process.
What evidence will you consider from me? Ask about photos, repair estimates, leases, rent rolls, closing statements, appraisals and property-specific issues.
Is the informal conference included? Confirm what happens before the ARB.
Is the formal ARB hearing included? Ask who attends and whether you can participate if you want to.
Do you handle Regular Binding Arbitration? If yes, ask about eligibility review, deposit, fee and representation.
What happens if district court is the better option? Ask whether the firm has attorneys, refers the case out, or ends representation after the ARB/arbitration stage.
Does the agreement renew automatically each year? Ask how and when you can cancel.
Can you show me the exact engagement agreement before I enroll? Read the contract rather than relying only on the marketing page.
A guaranteed reduction. No provider knows the final appraisal-district or ARB outcome before reviewing the property and evidence.
"No fee" language without a fee definition. Ask whether there is a minimum, enrollment fee, account fee, success fee, value-reduction fee, cancellation charge, or later-stage cost.
A fee that applies even without tax savings. Some fee structures are based on value reduction rather than tax savings, meaning a charge can apply in a year where your actual tax bill did not go down. Ask directly whether this is possible under your contract.
No clear answer about who handles the hearing. A brand name is not the same thing as knowing who will prepare and present your specific case.
No explanation of evidence. A credible provider should be able to explain the evidence categories it reviews without promising an outcome.
Confusing "consultant" with "attorney." Ask what license or registration each person holds and what stage of representation is actually included.
Unclear automatic-renewal terms. Annual protesting can be convenient, but only if you understand how future engagements and cancellation work.
Because this article is published by PropertyTaxes.Law, we do not include ourselves in the comparison table or call ourselves the "best." If you are considering us, apply the same checklist above: review our fee agreement, confirm who will handle your matter, ask what is included through the ARB, and ask how arbitration or litigation would be handled if needed. You can review our Texas Property Tax Protest service page and compare it directly with any other provider.
There is no single best provider for every owner. Compare the fee formula, TDLR licensing or applicable exemption, property-type experience, evidence process, ARB representation, renewal terms and post-ARB options. The best fit for a simple residence may be different from the best fit for a commercial portfolio or complex dispute.
Pricing varies by company and property, generally between 25% and 50% of first-year tax savings for contingency-based firms. A smaller number of firms also charge fees based on value reduction rather than tax savings, or a minimum flat fee per parcel — always confirm the exact fee structure in writing.
TDLR regulates property tax consultants, and people performing compensated consulting services generally must be registered when statutory requirements apply. Active Texas attorneys and Texas CPAs have registration exceptions, and other limited exceptions can apply.
Yes, a properly appointed and legally authorized representative can handle an ARB protest for an owner. Texas owners commonly use Form 50-162 to appoint an agent for property tax matters.
An agent may represent a property owner in Regular Binding Arbitration under the Texas process, subject to the applicable rules and filing requirements. Do not assume that every protest company offers RBA representation; confirm the firm's actual scope and fee.
No. An owner can file and present an ordinary protest personally or appoint an authorized agent. Attorney involvement may become more important when legal advice, district-court litigation, statutory interpretation or other legal issues are involved.
It depends. Professional help can be more attractive when a meaningful amount is at stake, the property is complex, you own multiple accounts, the evidence is technical, or you lack time to manage the process. A simple low-dollar factual correction may be economical to handle yourself.
Not automatically. Compare how savings are defined, what stages are included, evidence quality, who handles your case, renewal terms, whether a value-reduction fee can apply separately, and post-ARB options. A lower percentage can still be a poor value if the scope is limited or the fee base is defined differently.
No provider can know the final protest result in advance. A company can evaluate evidence and represent you, but the appraisal district, ARB, arbitrator or court controls the applicable decision.
Use the checklist above first. If you also want to evaluate PropertyTaxes.Law, review our protest service scope and ask us the same questions you would ask any company on this page.

Brandon and his team have proven they can perform with any product type we give them,
from industrial and office property to single and multi-family residential.
At a critical time when a property was in lease-up, we were faced with an unreasonable and unjustified assessment.
Brandon’s tenacity and responsiveness resulted in a fair assessment and the largest value change I've seen in my career.
Outstanding!! These guys are pros - they are great at what they do and great to work with.
