O'Connor property tax protest: do they actually save you money?

The arithmetic: what "saves you money" means in dollars

Every protest outcome converts to cash through one formula:

Tax savings = (value reduction) × (your combined tax rate), then subtract whatever your representation costs.

Your combined rate is the sum of every jurisdiction on your bill — school district, county, city, college, hospital, MUD, ESD. In most Texas metros that total lands somewhere near 2% to 2.7% of taxable value. Use the rate printed on your own tax statement, not an average.

Worked example, using a $50,000 reduction and a stated combined rate of 2.2%. Substitute your own reduction, your own rate, and the contingency percentage written in the contract you signed:

Line	Figure
Noticed market value	$650,000
Value after protest	$600,000
Value reduction	$50,000
Combined tax rate (stated)	2.2%
Gross tax savings	$50,000 × 0.022 = $1,100
Fee at a 25% contingency	$275 → net $825
Fee at a 40% contingency	$440 → net $660
Fee at a 50% contingency	$550 → net $550
Fee at a $199 flat evidence packet	$199 → net $901

Two structural notes fall out of that table. First, a contingency fee scales with the win, so a large reduction on an expensive property can cost several hundred to several thousand dollars in fees — which is exactly when representation can still be worth it, because you keep the majority. Second, on a small reduction, a percentage fee is cheap in absolute dollars but the whole outcome is small either way. Published contingency rates in the Texas market generally run from about 25% to 50% of first-year savings; the only number that matters to you is the one in your signed agreement and that firm's published terms.

Also check whether the fee applies to first-year savings only or renews, and whether any flat enrollment or administrative charge applies regardless of outcome.

What a contingency fee buys, and what it does not

What it buys: someone else handles filing, calendaring, the informal conference, and the ARB appearance; a book of business large enough to get efficient hearing scheduling; and a staff member who has sat in that district's hearing room hundreds of times.

What it does not buy: a different legal standard. The ARB weighs the same two grounds and the same evidence quality no matter who presents it, and under §41.43 the chief appraiser carries the burden to support the value by a preponderance of the evidence in the ordinary case. The Comptroller's Property Taxpayer Remedies booklet lays out the same remedies for represented and unrepresented owners.

What an agent must file to represent you: Form 50-162

Before any firm can act on your account, it files a Form 50-162 Appointment of Agent with the appraisal district under Tax Code §1.111. That appointment:

• Lets the agent file the protest, receive your notices, and appear at the informal meeting and the ARB hearing;
• Can be limited to specific tax years and specific properties, or left open until revoked;
• Stays in effect until you file a written revocation with the district — it does not expire because you stopped returning calls;
• Can authorize the agent to enter a settlement agreement with the chief appraiser under §1.111(e), and those agreements are final and binding on you.

It does not transfer ownership of the protest, waive your deadlines, or give the agent any evidentiary privilege. Texas property tax consultants are registered through TDLR, and you can verify a registration there.

The two grounds every protest rests on

Whoever stands up at the hearing is arguing one or both of these:

• Market value is too high — §41.41(a)(1). Evidence: comparable sales adjusted for size, age, condition, and location; repair estimates; closing documents if you bought recently.
• Unequal appraisal — §41.41(a)(2), decided under the standard in §41.43(b)(3): the appraised value exceeds the median appraised value of a reasonable number of comparable properties, appropriately adjusted. This is the ground that wins quietly and often, because it does not require the market to have fallen — only that your neighbors are carried at lower values per square foot. See how unequal appraisal works in Texas.

You can plead both on one notice of protest (Form 50-132, or the district's online portal). Deadline: May 15, or 30 days after the notice of appraised value is delivered, whichever is later (§41.44).

Informal settlement vs. the ARB hearing

Stage	What happens	Does a firm add leverage?
Informal conference with an appraiser	Most protests resolve here; appraiser can adjust the value on the spot	Somewhat — volume scheduling and familiarity with the district's adjustment grids
Evidence request (§41.461)	You may obtain the district's evidence at least 14 days before the hearing	No — the right is yours either way, and the request takes minutes
ARB hearing (§41.45)	Both sides present; the panel decides	Marginal — the panel weighs the exhibits, not the presenter
ARB written order (§41.47)	Determination mailed; starts the appeal clock	No

The honest split: a firm's edge is logistical and procedural. The evidence edge belongs to whoever assembled the better comparable set. That is why plenty of owners win alone, and why a DIY-versus-firm comparison usually turns on your time and your comfort in the room, not on a secret the firm holds.

After an unfavorable ARB order: who pays for the next round

Two appeal routes exist, and this is where contingency agreements diverge sharply:

• Binding arbitration under Chapter 41A, available for a residence homestead of any value or other property appraised at $5 million or less. You file a request with the appraisal district within 60 days of receiving the ARB order and submit a deposit; if the arbitrator's value is nearer to your opinion than to the ARB's, the district pays the arbitrator's fee and your deposit is refunded less the Comptroller's administrative portion. Details in our binding arbitration guide.
• District court appeal under Chapter 42 (§42.01, petition filed within 60 days of receiving the order). Realistic cost: filing fees, an appraisal, and counsel.

A contingency agreement typically covers the protest and ARB hearing only. Arbitration deposits, court filing fees, and expert appraisals are usually billed separately or declined — read the scope clause before assuming your firm will carry you past the ARB.

Which route fits your property

• High-value home with complex comps (acreage, custom build, few true matches): a represented protest or an independent appraisal usually earns its fee, because the reduction is large enough that even a 40% cut leaves meaningful net dollars, and the comp argument is genuinely hard.
• Straightforward homestead with a clear unequal-appraisal case (tract subdivision, dozens of near-identical neighbors, your value per square foot above the median): the evidence is mechanical. A flat-fee packet or a free analyzer run keeps 100% of the savings with you.
• Commercial or multi-parcel portfolio: representation generally wins on labor economics alone — income-approach arguments, multiple hearing dates, and potential 41A or Chapter 42 follow-through.

If you want the side-by-side on structure rather than reputation, see TaxStand vs. O'Connor. TaxStand is software, not a protest firm: checking whether you have a case is free, and the hearing-ready packet — comparable-sales and unequal-appraisal evidence, county filing instructions, and a pre-filled Form 50-132 — is $199 flat per property per year, with no percentage of your savings.

Frequently asked questions

Does O'Connor charge if they don't lower my value?

Contingency agreements are structured so the percentage fee applies only to tax savings produced by a reduction, meaning no reduction generally means no contingency fee. Check your signed contract for any separate enrollment, administrative, or renewal charges that apply regardless of outcome.

How does O'Connor's protest process work?

The firm files a Form 50-162 Appointment of Agent with your appraisal district, files the protest by the §41.44 deadline, attempts an informal settlement with an appraiser, and appears at the ARB hearing if no agreement is reached. Any fee is then billed against the first-year tax savings from the reduction.

Can I fire a property tax agent mid-year?

Yes. An agent appointment under Tax Code §1.111 stays in effect until you file a written revocation with the appraisal district, so revoke in writing and confirm the district processed it. Note that a settlement the agent already signed under §1.111(e) is final and binding, and fees earned before revocation may still be owed under your contract.

Do property tax protest companies actually work in Texas?

They are legitimate and many owners get reductions through them. The reduction comes from the evidence, though, and the ARB applies the same market-value and unequal-appraisal standards whether an agent or the owner presents it.

Is the sign-up fee worth it?

Run the math first: multiply your expected value reduction by your combined tax rate, then subtract the contingency percentage in the contract. If your homestead's capped assessed value sits well below market value, a reduction may produce no tax savings at all and no fee structure makes it worthwhile.

What do I get for free whether or not I hire anyone?

The right to protest on market value and unequal appraisal, the district's evidence at least 14 days before your hearing under §41.461, a hearing before the ARB, and the burden of proof resting on the chief appraiser under §41.43.
