Do it yourself free · a $39 flat-fee kit · a contingency firm · a flat-fee service · an attorney. Real named operators, the arithmetic in the open, and the cases where hiring someone is genuinely the better call.
Check your home FREE →Search "best property tax protest company in Houston" and every page you land on is written by one of them. This one is too — we sell a $39 flat-fee do-it-yourself kit, and you should read everything below knowing that. What we have tried to do instead of pretending otherwise is make the page useful even if you decide to hire somebody else: real names, only figures we could actually verify, the arithmetic shown so you can redo it with your own numbers, and an honest section on when a firm or an attorney beats doing it yourself.

| Route | What you pay | Does the fee repeat? | Who appears at the hearing |
|---|---|---|---|
| Do it yourself, no help | $0 | Nothing to repeat | You |
| Flat-fee DIY document kit (what we sell) | $39, one time | No. $39 whether you save $400 or $4,000 | You |
| Contingency-fee protest firm | Typically 25%–50% of first-year savings | Yes — every year they get a reduction | Their agent, on your behalf |
| Flat-fee full-service firm | Not published here — see §2 | Usually annual, per property | Depends on the service |
| Attorney | Not published here — see §2 | Depends on the engagement | The attorney |
The 25%–50% range is not our number and we did not estimate it. It comes from a 2026 Texas property tax protest industry cost breakdown published by Ownwell, a protest firm — a competitor describing its own industry. One of the highest-volume firms operating in the Houston area charges a flat 50% contingency fee. We have not independently audited every firm's pricing and we are not claiming the range covers all of them.

Ratings and review counts were read off each company's own public Google Maps business profile on August 6, 2026 and will have moved since. This table is not a ranking and it is not a warning list. Every company on it is a real, operating business, and most of them have a far stronger public review record than we do — we have none at all. What the table is for is showing you which category each one belongs to, because the category is what determines how you get charged.
This is the whole comparison in one idea, and it is the part the sales pages skip. Here is one real house, priced with the actual 2026 tax rates HCAD publishes for a home inside the City of Houston and Houston ISD. Every step is shown so you can redo it with your own numbers.
The $25,000 reduction is an assumption, chosen to be ordinary rather than flattering — not a prediction, not a typical result, not a promise. HCAD and the ARB decide every protest. The rates and the exemption percentages are real, from HCAD's own published jurisdiction rate file. The full unit-by-unit working is on the cost page, including why a $25,000 cut in appraised value only moves taxable value by $20,000 at units that grant the §11.13(n) 20% local option.
Assume the same $25,000 reduction is achieved each year — again, an assumption and not a forecast, because HCAD and the ARB decide each year independently.
| Route | Year 1 — you keep | 3 years — you keep | 5 years — you keep |
|---|---|---|---|
| Do it yourself, no help | $425.79 (pay $0) | $1,277.37 (pay $0) | $2,128.95 (pay $0) |
| Our $39 flat-fee kit, bought each year | $386.79 (pay $39) | $1,160.37 (pay $117) | $1,933.95 (pay $195) |
| Contingency agent at 25% | $319.34 (pay $106.45) | $958.03 (pay $319.34) | $1,596.71 (pay $532.24) |
| Contingency agent at 50% | $212.89 (pay $212.90) | $638.68 (pay $638.69) | $1,064.47 (pay $1,064.48) |
Gross saving over five years is $2,128.95 in every row — the same reduction, the same house. The only thing that changes is what comes off the top.
A comparison that concludes "always pick us" is an advertisement. These are the situations where hiring is the right answer, and they are common. Texas Tax Code §1.111 expressly allows a property owner to appoint an agent using Comptroller Form 50-162 — this is a legitimate, regulated service.
Whichever way you go, these are the four answers that actually differentiate one contract from another. Ask for all four in writing.
Protesting your value is worth doing, and it is not the biggest lever on your bill. On the very same $350,000 example home, the general residence homestead exemption — $140,000 off school-district taxable value under Texas Tax Code §11.13(b), plus Harris County's 20% local option under §11.13(n) — works out to about $2,706.90 a year. That is more than six times the $425.79 protest reduction above, and it costs nothing to claim.
How often is that lever left unpulled? Counting HCAD's own public appraisal roll, 328,310 of Harris County's 1,157,293 single-family homes have no homestead exemption on record — 28.4%. That page publishes the counting method, the same figure for thirteen named areas, and the honest limits: a home with no exemption on record is not evidence that anyone is overpaying, because rentals, second homes, inherited or estate-held property and very recent purchases all legitimately have none.
A caution on the $2,706.90, because a single countywide figure would mislead: the saving depends on your school district and your city. Houston ISD's rate is 0.8783 per $100; Spring Branch ISD (1.0231) and Alief ISD (1.0072) are both higher, and municipal utility districts run higher still.
Filing your own protest is ordinary here, not unusual. From HCAD's own Annual Comprehensive Financial Report for FY2025: 567,154 protests were filed in Harris County in 2025 by owners and professional consultants together, up 9.77% on 2024. Of the protests that came through HCAD's online iFile system, 85,541 were filed by the property owner personally and 74,862 by paid agents — more owners than agents. A further 15,633 owners uploaded 137,021 of their own evidence files.
HCAD's report does not break down how protests filed by mail, in person, or by agents outside iFile split between owners and agents, so we cannot tell you that and we are not going to guess. It also does not publish outcomes by representative, which is why no win rate appears anywhere on this page — including ours.
Under Texas Tax Code §41.44(a), the protest deadline is May 15, or 30 days after your notice of appraised value was delivered — whichever is LATER. It is never a bare "May 15": if your notice arrived late, your deadline moves with it. No fee structure helps you if the protest was never filed. §41.44(b) allows a late protest for good cause, but only if filed before the ARB approves that year's appraisal records — do not plan around it. Our missed-the-deadline guide covers what remains possible afterwards.
The cheapest route is not a company at all — filing it yourself costs $0, and HCAD charges no fee. Among paid options, the lowest published price on this page is our $39 flat-fee kit, but we could not verify a current fee for most of the firms named in §2, so we cannot honestly rank them on price and we are not going to pretend otherwise.
We have no basis to say, and anyone who tells you otherwise on a page like this is selling something. Both are real, established businesses with strong public review records. What we can tell you is how the fee structures differ, which is what §1 and §3 are for.
Under a pure contingency structure, no reduction generally means no fee — that is the appeal of it. Read the contract for administrative, filing or annual charges that apply regardless of outcome, and for automatic renewal.
Only you can answer that. The $39 buys prepared documents and comparable-property evidence, not representation — you can build the same case yourself from HCAD's public records at no cost. If your likely reduction is small, the free route is the better deal, and we would rather say so than sell you a kit you do not need.
Generally yes, but read your agreement: agent appointments under §1.111 and the contracts around them have their own termination terms and dates. Nobody can require you to have an agent (§1.111(g)), but you can be contractually bound to one you already appointed. Ask them, in writing.
Protesting is a right the Tax Code gives you, and exercising it is not a reason for a higher appraisal. Values are re-set every year from market data regardless.
No to both. We prepare documents and evidence; you file and appear on your own, under your own right under §41.41. See §9.
