DIY vs Hiring a Firm
Three honest options — and the one variable that picks for you is whether you have time to attend the ARB hearing. Here’s how each path actually shakes out.
Your Three Options
If you can’t attend
Hire a firm
25–40% of first-year tax savings, billed only on a reduction.
The firm files, attends, and negotiates. You sign one form and wait for the outcome.
When a firm fits →If you’ll attend the hearing
Our $50 packet
Flat fee. You file, attend the hearing, and keep 100% of any reduction.
We compile the comparable-property evidence and pre-fill the forms. You bring the packet to your hearing.

Just file for free
$0. Form 50-132 from the Texas Comptroller. We’ll show you how.
Filing is your right under Texas law. Even with no formal evidence, many informal protests result in a reduction.

If You Don’t Have Time, Hire a Firm
This is the clearest call in the matrix. If you can’t take a half-day off work to attend an ARB hearing, hiring a %-based firm is by far the better option. They appear on your behalf, present evidence, and negotiate — all the work transfers to them. You sign one engagement letter and get an outcome notice in the mail.
Consider professional representation when any of these apply:
- You can’t take time off for the informal meeting and possible follow-up ARB hearing
- Your property is valued over $2M — the math on contingent fees usually works in your favor at that level
- Your property has highly unusual features (commercial mixed-use, large acreage, waterfront with no comparable sales, custom construction)
- Your informal hearing was unsuccessful and you want to escalate to a formal ARB hearing with someone else carrying the conversation
- You simply don’t want to present your own case — that’s a valid preference
A firm taking 25–40% of your first-year savings is fair pricing for representation. If you don’t have the time to attend, that’s the cost of someone else doing the work.
If You Have Time, Our $50 Packet Saves the Research Hours
For owners who can attend their own hearing, the comparable-property research and form preparation is the time sink — not the hearing itself. A typical informal meeting runs 15–30 minutes; a formal ARB hearing about 15 minutes.
What the $50 packet includes:
- Comparable-property evidence (10 equity comps + sales comps from public records)
- Land-size and square-footage adjustments applied to each comp
- Pre-filled Form 50-132 (Notice of Protest) and Form 50-283 (Affidavit of Evidence)
- Step-by-step per-county filing directions (online, mail, in person)
- A one-page hearing note card you talk from at the meeting
You file the protest yourself, present your own evidence, and keep 100% of any reduction. See the methodology in detail →
If You Want to Start Simple, Just File
If $50 feels like too much friction, or you’d rather see how the informal meeting goes before investing in formal evidence, file Form 50-132 directly with your county appraisal district. The form is free, filing is your right, and even an informal meeting with bare-minimum evidence often results in a reduction.
The single biggest mistake Texas homeowners make is not filing at all. The whole reason this page exists is to point out that filing costs you nothing but time — whatever path you pick.
What We Are, What We Aren’t
TaxProtestTx is a document preparation service. We compile public county appraisal data and pre-fill the official Texas protest forms. The owner reviews the data, decides whether to file, files the protest themselves, and presents their own evidence at the hearing.
We are not a property tax consultant, agent, attorney, or hearing representative. We do not appear before appraisal districts or the ARB on anyone’s behalf. Tex. Occ. Code Chapter 1152 distinguishes document preparation from licensed property tax consulting; we sit on the document-preparation side of that line by design.
That distinction is why this page recommends a firm — not us — for owners who can’t attend their hearing. Hearing representation is a real service that has real value; we just don’t provide it.
What the Independent Data Shows
Per the Squaredeal Tax Harris County A1 dataset (2017–2025; cross-corroborated by Kinder Institute / January Advisors), DIY filers with prepared evidence have matched or exceeded agent-led median dollar reductions in every year of the dataset. In 2025 specifically:
- DIY median dollar reduction: $20,640
- Agent-led median dollar reduction: $13,202
- DIY success rate: 71% — meaning 29% of DIY filers got no reduction
- Agent success rate: 16% on the headline figure (the agent-led pool is much larger and includes many submissions that never advance past an initial review)
- Approximately 35% of Harris County’s 1.12M single-family homes filed a protest in 2025
What the numbers don’t control for: time invested per outcome. A firm’s broad-volume model is rational because each filing costs the owner zero hours. Our $50 packet’s value proposition is the opposite trade-off: for the hours you’d spend researching comps from scratch, we hand you a hearing-ready document for a flat fee, and you keep 100% of any reduction.

The Caveats That Matter
71% is not 100%. Three out of ten DIY filers in 2025 Harris got no reduction. The data measures filers with prepared evidence; an unprepared filing can fare worse.
Self-selection effect. After weak DIY outcomes in 2023–2024, casual DIY filers dropped out of the system, leaving only more prepared homeowners. The 71% rebound reflects who stayed, not who started.
Harris is one county. The numbers above are Harris-specific. Montgomery, Dallas, Travis, and other counties may run differently — treat the Harris data as directional.
Hearing presence matters. The DIY median assumes you showed up. If you can’t attend, you’re not in the DIY-success dataset — you’re in the no-protest-filed dataset, where the outcome is always zero.
Why We’re Telling You All of This
TaxProtestTx exists to help Texas homeowners get a fair shake on equity valuation — not to win a referral race against firms. The single biggest mistake homeowners make is not protesting at all, usually because the process feels intimidating or they assume it costs money to file.
It doesn’t. The form is free. The hearing is free. Filing is your right. The only resource you spend is time — and if you don’t have time, a firm is the better answer than not protesting.
We built this because the friction of researching comparable properties was the single biggest reason owners who could attend their hearing didn’t bother filing. The $50 packet collapses that research into a flat-fee artifact. It’s one of three legitimate paths — pick the one that fits.
