The best Texas property tax protest service comes down to how much you want to do yourself and whether you'd rather pay a flat fee or a percentage of your savings. Texas is unusual: filing a protest yourself is free, so a paid service earns its keep on the evidence, the paperwork, and getting it filed on time. For homeowners who want it fully handled at a predictable price, a flat-fee done-for-you service like TaxAppeal USA ($89 flat) is the strongest value — you keep 100% of your savings. DIY packet tools like AppealDesk ($49) are cheaper but you file yourself. Contingency firms like O'Connor and Ownwell take 25–50% of your savings every year. Here is an honest 2026 comparison.
How a Texas property tax protest works
Each spring your county appraisal district (HCAD, DCAD, TAD, TCAD, and others) mails a Notice of Appraised Value. You then have until May 15 — or 30 days after the notice was mailed, whichever is later — to file a protest. Texas accepts a timely postmark, so you do not need the protest physically received by the deadline, and there is no county filing fee: protesting is free. That means paid services compete purely on evidence quality, convenience, and whether they file and represent you.
The three types of Texas protest services
Almost every Texas option falls into one of three models.
- ✓DIY document tools — you buy an evidence packet and file it yourself (e.g., AppealDesk, $49). Cheapest, but you handle the filing and any hearing.
- ✓Flat-fee, done-for-you — a fixed price and the service prepares AND files your protest (e.g., TaxAppeal USA, $89 flat). You keep 100% of your savings.
- ✓Contingency firms — no upfront fee, but they take 25–50% of your first-year savings, every year you re-file (e.g., O'Connor, Ownwell, Texas Protax).
Comparing the top Texas protest services in 2026
Here is how the main options stack up for a Texas homeowner protesting a single home.
- ✓TaxAppeal USA — $89 flat. Done-for-you: comparable-sales analysis, a protest letter citing Texas Tax Code §41.41 and §41.43, filed by USPS certified mail. You keep 100% of savings. Serves TX, GA, FL, AL, AR.
- ✓AppealDesk — $49 flat, DIY. Sends you an evidence packet and filing guide; you file and, if needed, attend the hearing yourself. All 50 states.
- ✓Ownwell — contingency, ~25% of first-year savings, and it auto-renews each year. Done-for-you including informal hearings. Operates in several states including Texas.
- ✓O'Connor — contingency, 25–50% of savings. Very large Texas firm (since 1974) that handles ARB hearings; the percentage repeats every year you re-file.
- ✓Texas Protax / Five Stone — contingency (roughly 33–40%); full-service including hearing representation, concentrated in the major metros.
The flat-fee vs contingency math
Because Texas reappraises every year, a contingency fee repeats annually — that is where the cost adds up. On a $1,800 annual saving, a 25% contingency is $450 every year, versus $89 once with a flat fee. Over five years that is roughly $2,250 in contingency fees versus about $445 flat. The higher your savings, the wider the gap.
Which Texas service is best for you?
It depends on your priorities.
- ✓You want it handled at a flat cost and to keep 100% of savings — TaxAppeal USA ($89 flat, done-for-you, certified-mail filing).
- ✓You want the cheapest option and will file yourself — AppealDesk ($49) or another DIY tool.
- ✓You have a complex or high-value property and want in-person ARB representation — a full-service contingency firm may be worth the percentage.
- ✓You plan to protest every year — a flat fee compounds in your favor versus a repeating percentage.
The bottom line
For most Texas homeowners who want their protest prepared, filed, and documented without doing the work or giving up a slice of their savings, a flat-fee done-for-you service is the best fit. TaxAppeal USA runs the comparable-sales analysis, drafts a protest citing the correct Texas Tax Code sections, and files by certified mail — flat $89, and you keep every dollar you save. If you're comfortable filing yourself, a $49 DIY packet works; if you want in-person ARB representation on a complex property, a contingency firm is an option — just know you'll pay that cut every year.
