Three ways to challenge an assessment. The right one depends on how much you want to do yourself.
Contingency rates and coverage are as published by those companies and change — check their current terms. A contingency firm can be the better choice if you want someone else to handle the filing and the hearing.
And compared to the tax-data sites you'll find on Google
Most property-tax reference sites publish one dataset and never revisit it. The figures below are what separates us — and they're checkable.
| Property Tax Edge | Typical reference site | |
|---|---|---|
| Tax-rate data | 2026 Tax Foundation figures | Commonly a Census survey from 2009–2010 |
| Appeal deadlines | All 51 confirmed against primary sources | Usually absent entirely |
| Shows its sources | Every figure, with the date it was checked | Rarely, if ever |
| Tells you when it's unsure | Yes — unconfirmed data is labelled | No |
Many American Properties Are
Assessed Above Market Value
Assessments are mass-generated and errors are common. Most homeowners don't know they can appeal — or how to build a strong case when they do.
Average Annual Property Tax Bill
The average U.S. single-family property tax bill was $4,427 in 2025, according to ATTOM — up 3% year over year. According to the National Taxpayers Union Foundation, experts estimate that 30–60% of taxable property in the U.S. is over-assessed.
Homeowners Never Appeal
Most eligible homeowners never file an appeal — many don't know they can. The National Taxpayers Union Foundation cites expert estimates that 30–60% of taxable property is over-assessed, yet typically fewer than 5% of taxpayers challenge their assessment.
Typical Appeal Window
Appeal windows are short in most states — often 25–90 days after notices go out. The right evidence, filed on time, is what gives an appeal its best chance.
