Do property tax protest companies actually work in Texas?

The mechanism: what actually decides a Texas protest

Every residential protest turns on evidence measured against a statute, not on who is standing at the table. Under §41.43(a), the chief appraiser has the burden of establishing value by a preponderance of the evidence in a protest of appraised value or unequal appraisal. That burden does not shift based on representation. If the district's evidence is weak and yours is specific, the board has a reason to lower the value whether you hired a firm or filed yourself.

There are two winning arguments, and they are worth stating plainly:

1. Market value above actual value

The district's appraised market value exceeds what the property would sell for on January 1. You prove this with closed sales of genuinely similar homes, a fee appraisal, a recent arm's-length purchase price, contractor bids for deferred maintenance, or photographs of condition problems the district's mass-appraisal model never saw.

2. Unequal appraisal

§41.43(b)(3) lets you win if your appraised value exceeds the median appraised value of a reasonable number of comparable properties appropriately adjusted — even if the district's value is defensible as market value. This is the equal-and-uniform argument, and it is the most mechanical, most winnable argument available to a typical homeowner, because it runs on the district's own published data. See our explainer on how unequal appraisal works in Texas.

The procedural scaffolding is identical for owners and agents: the deadline under §41.44 is May 15 or 30 days after the notice of appraised value is delivered, whichever is later (May 15, 2027 for most owners next season); §41.461 entitles you to the district's hearing evidence at least 14 days before the hearing; §41.45 governs the hearing; §41.47 governs the determination.

What the published outcome data actually says — and where to read it

Protest-outcome numbers get repeated online with no source attached. We will not reprint a figure we cannot point at. Here is where the real, citable data lives:

• Comptroller of Public Accounts — Property Value Study and MAP reviews (comptroller.texas.gov/taxes/property-tax/studies). The biennial Property Value Study tests whether each district's appraised values track market value, and the Methods and Assistance Program reviews grade appraisal and ARB procedures district by district. A district whose study results show values running above market is a district where market-value protests have more room.
• Comptroller, Property Taxpayer Remedies (Form 96-295) (PDF) — the state's own plain-language description of protest rights, ARB procedure, and appeal options after the ARB order.
• Appraisal district annual reports. Harris Central Appraisal District publishes protest and ARB volumes and dispositions in its reports library (hcad.org reports). Most large districts — Travis, Dallas, Tarrant, Bexar, Collin, Denton — publish comparable annual reports showing how many protests were filed, how many settled informally, and how many reached the ARB.
• Texas Real Estate Research Center at Texas A&M (trerc.tamu.edu) for independent research on Texas appraisal, protest behavior, and property tax burden.

Two patterns hold across those district reports year after year, and they are the honest headline: a large share of protests are resolved informally with the appraisal staff before an ARB hearing ever happens, and a meaningful share of protested accounts end the season at a lower value than the notice. Look up your own county's report for the current year rather than trusting a firm's marketing average.

Where firms genuinely add value

Situation	What representation actually buys
Commercial, multifamily, or income-producing property	Income-approach modeling, rent rolls, and appraiser-to-appraiser negotiation the district expects
Many properties across several counties	Parallel filing and hearing scheduling in districts with incompatible calendars
Owner cannot attend a weekday hearing	An agent appears; a missed hearing usually means the noticed value stands
Follow-through after an unfavorable ARB order	Filing §41A binding arbitration or a §42.01 district court appeal — see our binding arbitration guide
Complex valuation disputes (partial completion, litigation history, unusual use)	Experience arguing facts that mass appraisal handles badly

Where homeowners typically match firm outcomes

For an ordinary single-family home, the evidence that wins is public and formulaic. Owners regularly match agent results when:

• The account has a clean unequal-appraisal case — the district's own appraised values on a reasonable number of adjusted comparables sit below yours.
• Condition issues are documented with photos, dated contractor bids, and inspection reports.
• The matter settles informally with an appraiser before the ARB, which is how most residential protests end.
• The owner reads the district's §41.461 evidence packet before the hearing and rebuts the specific comps in it.

What an O'Connor-style contingency protest is

O'Connor & Associates, Ownwell, Texas Tax Protest, and similar firms are licensed tax agents. You sign an appointment of agent form, they file the protest, negotiate informally, and appear at the ARB if needed. They typically charge a contingency fee in the 25–50% range of first-year tax savings, with no upfront cost. These are legitimate businesses, and for owners who will not otherwise file, a 50% share of a reduction beats 100% of nothing. We break the arithmetic down in does an O'Connor protest actually save you money.

Contract terms worth reading before you sign

• Auto-renewal. Many agreements roll forward every tax year until revoked in writing. Know how to revoke the agency appointment and by when.
• Fee basis. A fee computed on market-value reduction is not the same as a fee on tax savings. On a capped homestead under §23.23, market value can drop without your taxable value or bill moving at all.
• Savings you would have received anyway. The 10% homestead cap and the temporary non-homestead cap under §23.231 (the circuit breaker) limit taxable value growth automatically. Confirm the fee is not calculated on limitations the statute already gave you.
• Multi-year or multi-property scope. Check whether signing for one account sweeps in every parcel you own.

Deadlines and forms do not change when you hire someone

The §41.44 deadline, the Comptroller's Form 50-132 Notice of Protest, and the §41.461 evidence-exchange rights apply identically to owners and agents. Hiring a firm in late May does not reopen a deadline that has passed. If you want to understand the sequence end to end, see what happens at a Texas ARB hearing.

TaxStand is software, not a protest firm. Checking whether you have a case is free — the analyzer pulls your appraisal district record and runs the equal-and-uniform comparable analysis. If the evidence supports a protest, a hearing-ready packet with comparable sales, the unequal-appraisal analysis, county filing instructions, and a pre-filled Form 50-132 is $199 flat per property per tax year, with no contingency and no share of your savings.

Frequently asked questions

What percentage of Texas protests result in a reduction?

There is no single statewide published rate, and any firm quoting one without a source is guessing. Look up your own county's appraisal district annual report, which typically shows protests filed, informal settlements, and ARB dispositions for the year.

Can the ARB raise my value at the hearing?

Yes. The board determines value under §41.47 and is not limited to the noticed figure, though an increase is uncommon in residential protests and the district still carries the burden of proof under §41.43(a).

Do I still owe a fee if the protest firm gets no reduction?

Under a true contingency agreement, no — the fee is a percentage of savings, typically 25% to 50% of first-year savings. Read the contract for flat administrative fees, minimum charges, and whether the percentage is computed on tax savings or on market-value reduction.

Is the protest deadline the same if I hire someone?

Yes. Tax Code §41.44 sets the deadline at May 15 or 30 days after your notice of appraised value is delivered, whichever is later, regardless of whether you or an agent files.

Is it worth protesting if my homestead value is already capped at 10%?

Often yes, because the market value you let stand this year becomes the baseline the cap grows from next year. But confirm whether a reduction actually lowers this year's taxable value before paying anyone a percentage of it.

What is an O'Connor property tax protest?

It is a contingency-fee protest handled by O'Connor & Associates, a licensed Texas tax agent firm. You appoint them as your agent, they file and argue the protest, and they keep a percentage of the resulting tax savings.
