Success rate is the share of well-prepared protests (with comparable-sales evidence) that result in a reduced value. “% over-assessed” comes from our statewide over-assessment study where county-level data has been computed; a dash means that figure is not yet published for that county.
Is protesting worth it? The math
The decision comes down to one comparison: the cost of protesting versus the savings if you win. With a flat-fee packet, the cost is fixed at $49, one time. The average successful protest in these counties saves about $687 per year, and because a lower assessed value carries forward, that saving tends to repeat.
At those numbers, a single successful year returns roughly 14x the cost of the packet, and there is no downside: a protest can never raise your value. The one case where it is not worth it is if you are already assessed at or below comparable homes, which is exactly why you should start with a free check.

About this data
Success rates reflect the share of well-prepared protests, those filed with comparable-sales evidence, that result in a reduced assessed value, based on appraisal-district outcome patterns and our own protest data as of June 2026. Average savings is the typical annual property-tax reduction in each county. The over-assessment share is drawn from our statewide over-assessment study, which applies each county's unequal-appraisal comparison to its 2026 public appraisal roll.

Frequently asked questions
How often do property tax protests win in Texas?
Across the 22 Texas counties we track, well-prepared protests succeed roughly 78% to 89% of the time, averaging about 82%. Success means the assessed value was reduced. The biggest driver is evidence: protests backed by 3 to 7 strong comparable sales win far more often than protests with no documentation.
Is protesting property taxes worth it?
For most over-assessed Texas homeowners, yes. The average reduction across these counties saves about $687 per year, and that saving repeats every year the lower value holds. Against a one-time $49 flat-fee packet (and zero ongoing cost), even a single year's savings typically pays for it several times over. The only homeowners for whom it is not worth it are those who are already assessed at or below comparable homes.
Why do success rates vary by county?
Success rates differ because appraisal districts use different neighborhood definitions, data quality, and informal-hearing practices, and because some markets cooled faster than assessments did. Counties where assessed values lag actual sale prices, or where the district groups dissimilar homes together, tend to produce more winnable cases. Your individual odds depend far more on your specific comps than on the county average.
Does a higher success rate mean I will definitely win?
No. A county success rate is the share of well-prepared protests that result in a reduction, not a guarantee for any single property. If your home is genuinely assessed at or below comparable homes, you will not win regardless of the county. That is why the first step is always a free over-assessment check, to confirm you have grounds before you file.
What is the average property tax savings from a successful protest?
Across the counties we track, the average successful protest saves about $687 per year, with some counties averaging over $1,150. Your actual savings depend on how over-assessed your home is and your local tax rate. A free analysis estimates your specific overpayment in about 30 seconds.
