Every spring, Texas homeowners who want help with their property tax protest face the same choice: hire a flat-fee service or sign up with a contingency firm that takes a percentage of whatever they save. The contingency model sounds appealing — you pay nothing upfront and only pay if the protest succeeds. But once you run the actual numbers, the math almost always favors a flat fee. Here is an honest look at both models, who each one benefits, and exactly how much the choice costs or saves you over time.
How the Two Models Work
A flat-fee property tax protest service charges you a fixed amount regardless of your outcome. You pay upfront and keep 100% of whatever you save. A contingency-fee service charges nothing upfront but takes a percentage of your first-year tax savings if the protest is successful. The industry standard contingency rate in Texas ranges from 25% to 50% of first-year savings, with most major firms charging 35-40%.
- ✓Flat fee: Pay $89 regardless of result — keep 100% of all savings
- ✓Contingency 25% (Ownwell): On a $1,800 saving, you pay $450 — keep $1,350
- ✓Contingency 40% (Texas Protax, Five Stone): On a $1,800 saving, you pay $720 — keep $1,080
- ✓Contingency 50% (O'Connor/CutMyTaxes): On a $1,800 saving, you pay $900 — keep $900
- ✓Break-even point: At 25% contingency, flat fee wins on any saving above $356
The 5-Year Math: Why This Is Not a Close Call
Texas reappraises property annually, which means the contingency fee repeats every year you use the service. The gap compounds dramatically over multiple years.
- ✓Year 1 — TaxAppeal: $89 fee, you keep $1,711 | Contingency (25%): $450 fee, you keep $1,350
- ✓Year 2 — TaxAppeal: $89 fee, you keep $1,711 | Contingency: $450 fee, you keep $1,350
- ✓Year 3 — TaxAppeal: $89 fee, you keep $1,711 | Contingency: $450 fee, you keep $1,350
- ✓Year 4 — TaxAppeal: $89 fee, you keep $1,711 | Contingency: $450 fee, you keep $1,350
- ✓Year 5 — TaxAppeal: $89 fee, you keep $1,711 | Contingency: $450 fee, you keep $1,350
- ✓5-YEAR TOTAL — TaxAppeal total fees: $445, you keep $8,555 | Contingency total fees: $2,250, you keep $6,750
When the Contingency Model Makes Sense
Contingency fees are not always the wrong choice. If your expected savings are very small — say $150 or less — the flat-fee cost may actually exceed what the contingency firm would charge. And if you want full legal representation through multiple hearing levels including binding arbitration, a full-service contingency firm provides services that go beyond what a flat-fee filing service offers. For most residential homeowners with expected savings above $400-500 per year, the flat fee is the better economic choice.
- ✓Contingency may make sense if: Expected annual savings are under $200 (contingency fee would be under $50)
- ✓Contingency may make sense if: You have a complex property that benefits from expert in-person ARB representation
- ✓Flat fee clearly wins if: Expected savings are $400+ per year (which describes most Texas homeowners)
- ✓Flat fee clearly wins if: You plan to protest multiple years (savings compound dramatically)
- ✓Flat fee clearly wins if: You want simplicity — pay once, result is yours to keep entirely
The Hidden Costs of Contingency Firms
Beyond the headline percentage, some contingency firms have additional cost structures worth understanding. Large firms like O'Connor use auto-enrollment: once you sign up, they file on your behalf every year and bill you without requiring re-authorization. Some firms charge minimum fees — meaning if your savings are small, you pay a fixed minimum that can exceed your actual tax savings. And some firms' contingency percentages apply to market value reductions rather than actual tax savings, meaning you can be charged even when the reduction does not lower your tax bill.
- ✓Auto-enrollment: Many contingency firms automatically renew you each year — opt-out windows are easy to miss
- ✓Minimum fees: A $150 minimum on a $100 savings leaves you worse off than before you filed
- ✓Value reduction vs. tax savings: Some firms charge on the value reduction, not the actual bill reduction
- ✓Communication quality: Large volume firms often provide minimal updates; you may not know the result for months

Frequently Asked Questions
Is a flat-fee property tax protest service as good as a contingency firm? ▾
For filing the formal protest and presenting comparable sales evidence — yes. The key difference is in-person ARB hearing representation, which contingency firms offer and flat-fee services typically do not. Most protests resolve at the informal hearing level without ever requiring in-person ARB representation.
What is the break-even point between $89 flat fee and a 25% contingency fee? ▾
If your annual tax savings would be $356, the 25% contingency fee ($89) equals the flat fee ($89). Any saving above $356 means the flat fee keeps more money in your pocket. At the more common 40% rate, the break-even is just $222.
Do I have to sign up every year with TaxAppeal USA? ▾
No. TaxAppeal USA is a one-time transaction per protest year. There is no auto-enrollment, no subscription, and no recurring charge. You choose when to file.
Can TaxAppeal represent me at an ARB hearing? ▾
TaxAppeal USA's current service covers formal protest filing with evidence. For in-person ARB representation, you would attend the hearing yourself or hire a local licensed agent. Most protests in Texas resolve before reaching the formal ARB stage.
What is the average savings from a successful Texas property tax protest? ▾
Statewide, the median successful protest reduces taxable value by approximately 10-15%. On a $400,000 home that is a $40,000-60,000 reduction. At a 2% effective tax rate, that saves $800-1,200 per year — making the $89 fee a 9-13x return in year one alone.
How does TaxAppeal compare to Ownwell? ▾
Ownwell charges 25% of first-year savings with no upfront cost. TaxAppeal charges $89 flat with no contingency. On a $1,800 saving: Ownwell takes $450, you keep $1,350. TaxAppeal takes $89, you keep $1,711. Ownwell also auto-enrolls you annually; TaxAppeal does not.
