Which is better: self-filing your Texas property tax protest or using Ownwell?

The break-even formula

Every contingency decision reduces to one comparison:

Contingency fee × estimated tax savings versus your hours × what your time is worth.

To get the left side, you need an estimated tax saving, not a value reduction. Convert one to the other like this:

• Step 1. Find your combined tax rate. Take last year's tax bill, divide total taxes by the taxable value shown on it. In most Texas counties the result lands somewhere near 2% after homestead exemptions, but use your own number — school, city, county, hospital and community-college rates vary by parcel.
• Step 2. Estimate a realistic reduction in appraised value. Not the reduction you want; the one your comps and equity evidence actually support.
• Step 3. Multiply. Reduction × combined rate = first-year tax savings.
• Step 4. Multiply that by the contingency rate (commonly 25%–50% of first-year savings) to get the fee.

Worked example

Input	Example
Appraised value reduction won	$40,000
Combined tax rate from your bill	2.2%
First-year tax savings	$880
Fee at 25% contingency	$220
Fee at 40% contingency	$352
You keep, self-filed	$880

At a 25% fee, you are paying $220 to avoid roughly four to six hours of work — about $37–$55 an hour. At 40% on the same reduction, it is $59–$88 an hour. That is the entire decision. If your time is worth more than that and you genuinely will not do the work, hire it out. If the reduction is large, the arithmetic swings hard toward self-filing, because the fee scales with the savings while your hours do not.

The three things you must actually produce to self-file

Self-filing is a short list, not an open-ended project.

1. A timely Notice of Protest. The Comptroller's Form 50-132, or the district's online equivalent. Check both "incorrect appraised (market) value" and "value is unequal compared with other properties" so you preserve both arguments. See how to fill out Form 50-132.
2. Market-value comps. Recent sales of similar homes, adjusted for size, age, condition and location.
3. An unequal-appraisal comparison. Under §41.43(b)(3), you win if your appraised value exceeds the median appraised value of a reasonable number of comparable properties, appropriately adjusted. This is the argument most homeowners skip and it often does more work than sales comps, because it runs off the district's own appraisal roll. Our evidence guide walks through both.

Note the burden: under §41.43 the appraisal district must establish the value by a preponderance of the evidence at the hearing. You are not required to prove a specific number out of thin air; you are required to make the district's number look unsupported.

The one step that closes the information gap: §41.461

Protest firms are not working from secret data. Under §41.461, at least 14 days before your hearing the chief appraiser must inform you that you may inspect and obtain a copy of the data, schedules, formulas and other information the district plans to introduce at the hearing — free or for a small statutory copying charge. Request it. You then walk in knowing the district's comps and adjustments before you present yours, which is most of what an agent's familiarity buys you.

Bexar County, end to end

Bexar is a useful worked example because the Bexar Appraisal District runs a full online protest and evidence-exchange path.

Stage	What happens
April–May	BCAD mails the notice of appraised value under §25.19. Read the market value, the appraised (capped) value, and the protest deadline printed on it.
Deadline	Under §41.44, May 15 or 30 days after the notice was delivered, whichever is later. For the 2027 season that is May 15, 2027 for most owners.
File	Through the BCAD online portal at bcad.org, or by filing Form 50-132. Online filing also enrolls you in the district's online evidence exchange.
Informal	A meeting or online offer from a BCAD appraiser. Most residential protests end here. You can accept the offer or decline and go to the ARB.
ARB hearing	A short hearing under §41.45. You present, the district presents, the panel decides and issues a written order under §41.47.
After	Binding arbitration under Chapter 41A or district court appeal under §42.01, both with deadlines and deposits.

BCAD's own help site (help.bcad.org) documents portal registration and evidence upload. Budget about an hour to file and request evidence, two to three hours to build comps, and under an hour for an informal or ARB appearance. See what happens at a Texas ARB hearing and the deadline calendar.

When hiring a contingency firm clearly wins

• You live out of state and will not appear, even by phone or affidavit.
• You own several parcels; the per-property hours add up faster than the fees.
• The property is commercial, mixed-use or income-producing, where income and cost approaches matter.
• There is no clean comp set — unusual lot, acreage, a one-of-a-kind house.
• You will otherwise miss the deadline. A protest not filed is worth zero regardless of fee structure.

Ownwell, O'Connor, Texas Tax Protest and similar firms are legitimate licensed-agent operations doing ordinary work under Chapter 41. The criticism worth taking seriously is not that they fail to file; it is that homeowners sign multi-year contingency agreements for work they could have done in an afternoon.

Read before you sign any contingency agreement

• Auto-renewal. Does the agreement roll into the next tax year automatically, and what is the cancellation window?
• Basis of the fee. A percentage of tax savings and a percentage of assessed value reduction are very different numbers. Confirm which, and whether savings are computed against the district's noticed value or last year's value.
• Exemption work. Is a fee charged on savings from a homestead or over-65 exemption you were already entitled to?
• Appeals. Who decides whether to go to §41A binding arbitration, and who funds the arbitration deposit?
• Agent authorization. An appointment of agent gives the firm control of the protest; know how to revoke it.

The third option

DIY and contingency are not the only choices. TaxStand is self-serve software, not a protest firm: checking whether you have a case is free, and the $199 flat-fee packet (per property, per tax year, all 254 counties) includes comparable-sales and unequal-appraisal evidence, county filing instructions and a pre-filled Form 50-132. You file and argue it, and you keep 100% of any reduction. On the $880 example above, a flat fee is cheaper than a 25% contingency only if the reduction is small — so run your own numbers. Our TaxStand vs Ownwell comparison breaks that crossover down, and how to protest yourself covers the fully free path.

Frequently asked questions

Is Ownwell legit for Texas property tax protests?

Yes. Ownwell operates through licensed property tax consultants who file protests under Tax Code Chapter 41 like any other agent, and charges a contingency fee on first-year savings. The real question is not legitimacy but whether the fee is worth the hours it saves you.

Does Ownwell actually work, or would I get the same result myself?

Agents and homeowners are judged by the same standard: the appraisal district must support its value by a preponderance of the evidence under §41.43, and unequal appraisal under §41.43(b)(3) is available to anyone. A prepared homeowner who requests the district's evidence under §41.461 often reaches a similar outcome.

Should I sign up with Ownwell or just protest myself in Bexar County?

If you will file through the BCAD portal, request the district's evidence, and take the informal meeting, self-filing keeps 100% of the savings for roughly three to six hours of work. If you won't do those steps or would miss the May deadline, a contingency firm is better than not protesting.

How much do Texas property tax protest companies charge?

Most contingency firms charge roughly 25% to 50% of first-year tax savings. Confirm whether the percentage applies to tax savings or to the assessed value reduction, and whether the agreement auto-renews for future tax years.

What is the deadline to protest in Texas?

Under §41.44 it is May 15 or 30 days after the appraisal district delivers your notice of appraised value, whichever is later. For the 2027 season that is May 15, 2027 for most homeowners; the exact date is printed on your notice.

What if my homestead value is capped — is protesting still worth it?

Sometimes not in the first year. If the 10% cap in §23.23 already holds your appraised value below market, a market-value reduction produces no tax savings until it drops below the capped value, though it can slow future increases.
