The Pricing Comparison
All major property tax protest companies in Texas work on contingency — meaning you pay nothing upfront and only pay a percentage of your tax savings if they win. The key difference is how much of your savings they take.
| Company | Fee | What You Keep (on $1,000 savings) |
|---|---|---|
| OverAssessed | 20% | $800 |
| Ownwell | 25% | $750 |
| Home Tax Shield | 25% | $750 |
| Texas Tax Protest | 25-35% | $650-$750 |
| O'Connor & Associates | 30-33% | $670-$700 |
| NTPTS | 33% | $670 |
On a $1,000 annual tax savings, the difference between OverAssessed (20%) and O'Connor (33%) is $130/year — or $650 over 5 years. The fee you pay is the biggest differentiator between these companies.
