An appeal here can be won on comparable assessed values alone, without arguing what your home would sell for. Past 5% above comparable homes, relief is the prescribed remedy.
A primary residence is taxed on 55% of its value. If the county has yours recorded otherwise, fixing that is usually worth more than an appeal.

Not your state yet?
We add states one at a time, and only where a homeowner can actually win on the county's own numbers and where a win actually lowers the bill. Some states fail one of those tests, and we publish which ones and why.

Three steps to check and appeal your assessment
1. Find your home
We hold every published parcel from each county's assessment roll. Look up your address to see what the county recorded for it.
2. Check your exemptions
Many states tax a primary residence on only part of its value. If the county has yours classified wrong, correcting it often saves more than an appeal.
3. Get the evidence
Comparable assessments near you, adjusted for size, with every parcel number — plus the deadline and the form your county actually uses.
What the 2026 rolls show
We analysed 760,347 homes across 12 assessment rolls in Utah and Washington, DC. 125,500 of them — 16.5% — are assessed above comparable homes in their own neighbourhood by more than the threshold their own state law uses for an equalization claim. For a home in that group the typical difference is worth about $590 a year in tax.
Being above your neighbourhood's median is not proof of an error — about half of any group is. What matters is how large the gap is and how tightly comparable homes cluster. How we work that out →
How it works
- Find your home.
We hold the published assessment roll for every county we cover.
- See the comparison.
Your assessed value against comparable homes near you, adjusted so a small home is not penalised for being small, with every comparable's parcel number so you can check it.
- Check your exemptions.
Where your state reduces the taxable value of a primary residence, we check the county has it recorded. When it is missing, that is usually worth more than an appeal.
- File it yourself if it stacks up.
The evidence, the deadline and the form for your county — including the second-stage filing most people never reach.
What this is not
We do not estimate what your home would sell for. No automated valuation model, no appraisal — those are different things done under different rules. We compare the county's assessment of your home with the county's assessments of homes like it, because that is evidence the county cannot argue with. In states that never publish sale prices, it is the only comparison a homeowner can make at all.
We also publish which counties we cannot analyse and why: see coverage for every county →. Some rolls do not carry building sizes or neighbourhood names, and without those there is no honest comparison to make.
