What is the property tax appeal success rate?
The short answer
There is no single national figure, because success is tracked county by county, but the cleanest public data is high. Texas Comptroller figures show 94.66 percent of Hays County homeowners who protested informally in 2024 won a reduction, and across the Texas counties we track, evidence-backed protests succeed roughly 78 to 89 percent of the time. The informal stage settles most cases; formal hearings run somewhat lower. The single variable that decides your odds is the quality of your comparable evidence.
Why there is no single national number
Property tax appeals are decided by thousands of separate county boards, each reporting (or not reporting) its own outcomes, so a clean nationwide success rate does not exist, and anyone quoting one precise figure is guessing. What does exist is solid county-level data, and the best-documented comes from Texas, where the Comptroller publishes protest outcomes.
Those numbers are encouraging. In Hays County, 94.66% of homeowners who protested informally in 2024 won a reduction, after 99.63% in 2023 and 100% in 2021 and 2022. Across the 14 Texas counties we track, evidence-backed protests succeed roughly 78 to 89 percent of the time. The pattern, high informal success when the homeowner brings comparables, holds well beyond Texas.
Informal vs formal: where cases actually resolve
Success rate depends heavily on which stage you are at. Most protests never reach a formal hearing, in Harris County, only about 16% of 2024 protests went all the way to a formal Appraisal Review Board determination. The rest settled earlier, at the informal review, where an appraiser looks at your evidence and offers a number. Informal success rates are the high ones; formal-hearing rates run somewhat lower because the easy wins have already been settled out.
This is true in structure across states: New York's Board of Assessment Review, Florida's special-magistrate VAB hearing, New Jersey's County Board, Colorado's assessor review, all front-load a stage where a clean comparable table tends to settle the matter before any formal panel. The mechanics differ; the dynamic does not.
The variable you actually control
High baseline rates do not mean every protest wins big, the difference between a token trim and a four-figure cut is the comparable evidence. Homeowners who walk in with a clean table of similar properties assessed lower than theirs get reductions; those who argue that taxes feel too high usually do not. The free check shows how your assessment compares to similar properties in about 30 seconds, no signup, so you know your odds before you file. If the gap is real, the $49 protest kit comes pre-filled with the evidence that moves the number, and whether it is worth filing becomes an easy yes.
