O'Connor protests on your behalf as your appointed agent under Form 50-162 and charges a contingency percentage of the tax savings it produces; TaxStand gives you the comparable-sales and unequal-appraisal evidence plus a pre-filled Form 50-132 for $199 flat, and you remain the protesting party under Tax Code §41.41. The practical difference comes down to three things: who signs the paperwork, how the money moves, and who sits in the chair at the informal meeting and the ARB hearing.
The three structural differences
Who files. With a contingency firm, you sign the Comptroller's Form 50-162, Appointment of Agent for Property Tax Matters. From that point the firm signs the Form 50-132 Notice of Protest and becomes the party the appraisal district talks to. With TaxStand, nobody is appointed. You sign your own 50-132 (or file through your district's online portal), and your name stays on the file.
How you pay. Contingency firms bill a percentage of the first-year tax savings their protest produces — in the Texas residential market this is commonly in the 25–50% range, and the only number that matters is the one in the agreement you are actually signing, so read the firm's current published terms (O'Connor, Ownwell). TaxStand charges $199 per property per tax year, flat, with no subscription and no share of the reduction.
Who shows up. A firm's consultant handles the informal conference with the appraiser and, if it goes that far, the Appraisal Review Board hearing under §41.45. If you file yourself, you show up — by phone, video, or in person, depending on the district — or you submit a written affidavit. That is the real trade: your time versus a cut of the outcome.
Side-by-side comparison
| Item | Contingency firm (O'Connor, Ownwell, etc.) | TaxStand (self-filing) |
|---|---|---|
| Who signs Form 50-132 | The firm, as your appointed agent | You, the owner |
| Agent authorization | Form 50-162 required | None — no agent is appointed |
| Who receives CAD and ARB correspondence | The agent, under §1.111(f) | You, at the address on the appraisal roll |
| Informal meeting with the appraiser | Firm's consultant, usually in bulk settlement sessions | You, using the packet's evidence |
| ARB hearing | Firm's consultant appears | You appear, or file a written affidavit |
| How fees are computed | Percentage of first-year tax savings; terms vary by firm and year | $199 flat, per property, per tax year |
| No-reduction year | Typically no fee, but you also got no outcome | You already paid the flat fee; evidence is yours to reuse |
| Who keeps the savings | You, minus the contingency share | You, 100% |
| Escalate to binding arbitration (§41A) | Available; firm may or may not include it, and the deposit is yours | Available; you file the request after the ARB order |
| Licensing | Consultants are licensed by TDLR | Not applicable — software, not representation |

What an agent can and cannot do
Agent appointments are governed by Tax Code §1.111. A properly designated agent may file the protest, negotiate with the district, appear at the ARB, and — importantly — agree to a settlement value that binds you. The designation stays in effect until it expires by its own terms or you revoke it in writing; the Comptroller publishes a revocation form alongside 50-162.
Two consequences owners underestimate. First, once an agent is on file, the district generally routes notices and communications to the agent rather than to you (§1.111(f)), so your own mail can go quiet mid-season. Second, most districts will not hold a separate informal with the owner while an agent of record exists — you have traded your direct line to the appraiser for the firm's volume relationship with that office. Neither is a criticism of any firm; it is how the statute works.
Why "did they save me money" is the wrong question
Any reduction — from a firm or from you — is measured against the noticed value the district proposed on your §25.19 notice, not against last year's tax bill. A protest can succeed and your bill can still rise, because rates are set later by the taxing units.
Homestead accounts complicate it further. Under §23.23, the taxable value of a homestead cannot increase more than 10% per year over the prior year's appraised value plus new improvements. If your market/appraised value is well above your capped value, a protest that knocks the appraised value down may not move the capped taxable value at all — in which case there is no first-year tax savings to split, and no first-year benefit to you either, though it can reduce future-year headroom.
To check your own notice, find three lines: market (appraised) value, assessed/capped taxable value, and the difference. If the capped value is materially lower than the market value, ask any firm — or yourself — how far the market value has to fall before the tax bill changes. That one question is more useful than any advertised average savings figure.
TaxStand is self-serve software operated by Outlaw Holdings LLC. It is not a protest firm, not a licensed agent, and does not give legal advice. You file, you sign, and you argue your own protest.
Where Ownwell fits
Ownwell runs the same basic model as O'Connor — signed agent authorization, contingency fee on savings, firm appears for you — with different fee terms and a more consumer-software front end. The structural comparison in the table above applies to both. A line-by-line version is in TaxStand vs Ownwell.
Which model fits which owner
A full-service contingency firm usually makes sense if:
- You live out of state or out of the country and cannot attend a hearing.
- The property is commercial, multifamily, or income-producing, where the valuation argument is technical.
- You hold many accounts and want one vendor handling all of them.
- You have a complex unequal-appraisal case under §42.26 / §41.43(b)(3) requiring adjusted comparables and a median calculation you do not want to build.
- Your time is worth more than the contingency share, and you would otherwise not file at all.
Self-filing usually makes sense if:
- It is a single Texas homestead with a straightforward over-market or unequal-appraisal argument.
- You can spend an hour on an informal call or a short ARB hearing.
- You expect a meaningful reduction and would rather keep all of it than give up a quarter to a half of year one.
- You want to stay the party of record so you control any §41A arbitration decision afterward.
Deadlines and rights that apply either way
Your right to protest comes from Tax Code §41.41 and belongs to you, not to any vendor. Notices go out in April and May; the filing deadline under §41.44 is May 15 or 30 days after the notice was delivered, whichever is later — for most owners in 2027 that is May 15, 2027. At the hearing, §41.43 puts the burden on the district to support its value by a preponderance of the evidence, and §41.461 entitles you to the district's evidence package at least 14 days before the hearing. After the ARB issues its §41.47 order you can pursue binding arbitration under §41A or district court under §42.01.

Frequently asked questions
Do property tax protest companies actually work in Texas?
Yes — they are legitimate, licensed through TDLR, and they win reductions for many clients every season. What they cannot do is create a case that the evidence does not support, and they take a percentage of whatever they win.
Does O'Connor actually save you money?
Sometimes, and the honest answer depends on your account. O'Connor only bills when it produces tax savings, but on a homestead already limited by the 10% cap under §23.23 an appraised-value cut may not lower your taxable value at all, so measure results against your noticed value and your capped value, not last year's bill.
Can I fire my protest agent mid-season?
Yes. Under Tax Code §1.111 an agent designation lasts until it expires or you revoke it in writing with the appraisal district, and the Comptroller publishes a revocation form. Check your signed agreement first — the fee terms may still apply to work already done or to a value already settled.
Is TaxStand a property tax protest firm?
No. TaxStand is self-serve software that builds a hearing-ready evidence packet and a pre-filled Form 50-132. It is not a licensed agent, does not sign anything on your behalf, and gives no legal advice.
What does TaxStand cost compared to a contingency firm?
TaxStand is $199 flat per property per tax year with no subscription and no share of your savings. A contingency firm charges nothing up front and then takes a percentage of the first-year tax savings, commonly in the 25–50% range depending on the firm's current terms.
If I file the protest myself, can I still go to binding arbitration?
Yes. Once the ARB issues its determination under §41.47, an eligible owner can request binding arbitration under Chapter 41A or appeal to district court under §42.01. Staying the party of record means that decision is yours to make.
Is your appraisal out of line with your neighbors'?
TaxStand pulls your appraisal district record, runs the equal-and-uniform comparable analysis, and produces a hearing-ready protest packet. $199 flat — one property, one tax year. No contingency fee, no percentage of your savings. Live in 45 Texas counties.
