Is it worth protesting property taxes?

The case for yes

Three things make protesting worth it for an over-assessed home. First, the cost to file is near zero, free in Texas, New York, and Colorado, $15 in Florida, a modest fee in New Jersey. Second, the win rates are high when you bring evidence: the cleanest public data available, Texas Comptroller figures for Hays County, shows 94.66% of informal protesters won a reduction in 2024 (99.63% in 2023). Third, and most underrated, a reduction carries forward. You do the work once and the lower assessment keeps paying off every year you hold it.

The dollars are real. Our study of 4.8 million parcels across 14 Texas counties found about 1,000,000 over-assessed homes overpaying an estimated $1.5 billion a year, and a successful protest in those counties saves about $774 annually. Across high-tax states the stakes are bigger still, New Jersey's average bill runs around $9,300, so even a 5% cut is a few hundred dollars a year, compounding.

When it is NOT worth it (the honest part)

Protesting is not free money. If your assessment is already in line with comparable homes, neither a DIY appeal nor a paid firm will produce a meaningful reduction, and you will have spent an afternoon for a token cut or nothing. Roughly 1 in 5 homes in our Texas study were over-assessed by more than 5%, which means about 4 in 5 were not. The decision is not really should I protest, it is am I actually over-assessed.

A common worry: can protesting backfire and raise my assessment? In most states filing an appeal cannot increase your value, but a few jurisdictions allow the board to adjust in either direction under their ratio rules. For a clearly over-assessed home that is not a concern, but it is one more reason to file with real comparables rather than a hunch. Confirm your state's rule before filing.

Settle the question in 30 seconds

The whole decision hinges on one fact you can get for free: how your assessment compares to similar properties. The free check shows that gap in about 30 seconds, no signup. If there is no gap, you have saved yourself the trouble. If there is, you can file it yourself with the $49 protest kit's pre-filled comparable evidence and keep 100% of the savings, or hire a firm and give up a recurring cut. Either way, start with the fact.
