Most companies want to sell you a property tax appeal. We check first whether an appeal would actually save you money, using your county's own records, and we tell you the truth either way.
Check my home, freeNo account, no card, no catch. Live in King County, Washington, Cook County, Illinois, Cuyahoga County, Ohio, and Deschutes County, Oregon. And we now answer for all fifty states, even where the answer is that appealing cannot help you.
We come from consumer advocacy. Our background is helping people make good decisions about things that are genuinely hard to judge before you hand over the money, and being straight with them when the honest answer is to keep their wallet closed.
Property taxes turned out to need exactly that. A notice shows up in the mail, you cannot tell whether appealing is worth your time, and every company offering to help has a reason to tell you yes.
So we built the check first, and made it free. It reads your county's own records and its own recent sales of homes like yours, then tells you what they actually show. Most people who run it are told not to appeal. That is the tool doing its job.
We are pouring ourselves into getting this right one county at a time, because we would rather be genuinely useful in a few places than vaguely useful everywhere.
Nothing else. No account, no email required, and we store nothing about your address.
Your assessed value, your property's details, your filing deadline, and the county's own recent sales of comparable homes.
What the sales actually show against your assessment, and whether that is worth acting on. Often it is not.
Before selling anything, we read King County's own record of every appeal it decided in a year, looked up the property type behind every parcel number in it, and read dozens of written decisions from Washington's Board of Tax Appeals. Here is what those documents say about houses specifically.
Read the full analysis of all 951 cases. From the county's 2024 hearing record. We separated houses from apartment buildings, offices and warehouses, because mixing them produces a flattering number that means nothing to a homeowner. You will see much higher win rates quoted elsewhere.
Then we will build you the packet, and during our launch season it is free. We are new, and instead of charging while we prove ourselves, we ask early users for honest feedback. Everything in the packet comes from your county's own records with the source printed next to it, so your appeal board can look up every number in its own system. The whole free deal is spelled out here.
We only build a packet when the county's own records support the appeal. If they do not, we tell you not to file, free packet or not, because handing you a losing case would waste your afternoon and our name. And when a price returns in January 2027, the money-back guarantee returns with it.
Washington, King County. The full check, using the assessor's own comparable sales tool and your exact filing deadline from the county's appeal system. Detached houses for now, not condos.
Illinois, Cook and Lake Counties, including Chicago. Illinois decides these appeals on fairness between neighbors rather than on sale prices, so we compare what similar homes are assessed per square foot, which is the exact test the state appeal board applies. We also show your township's appeal window and the year it is next reassessed, because a reduction won in Cook County holds until the next reassessment and the timing changes what a win is worth by up to three times. Lake County publishes more about each home than any county we have found, including the building assessment on its own, which is exactly what the Illinois argument runs on.
Ohio, Cuyahoga and Franklin Counties, including Cleveland and Columbus. Ohio decides these on market value, so we compare what homes genuinely like yours actually sold for. One thing we tell you that nobody else does: your school district can file against you within 30 days and argue for a higher value, so a weak case here is riskier than in most states.
Georgia, Fulton County, including Atlanta. Georgia decides these on market value, so we compare what homes genuinely like yours actually sold for. Win here and the value is frozen for three tax years, so one win pays three times, and from 2027 a statewide cap limits how fast assessments rise from whatever base you are on.
New Jersey, all 564 municipalities. The whole state, because New Jersey publishes every assessment in one place. It also decides these on arithmetic rather than opinion, so we can tell you the exact dollar figure your home has to come in under before a county board is required to cut your assessment. Nobody else publishes that number. We also tell you when an appeal would raise your assessment, which the law requires here and which we have not found anywhere else.
Oregon, Deschutes County. A quick screen that tells you whether Oregon's Measure 50 cap makes an appeal pointless for you, which for most Oregon homeowners it does.
Georgia freezes your value for three years if you win, and two things take it away again. We read the statute and the bill that changed it by one word.
Your Ohio home went up 40 percent, and your tax bill probably will not. Summit County just mailed 262,000 reappraisal notices. Whether your bill rises turns on one thing almost nobody explains.
The appeal form takes about 20 minutes, and the deadline is what catches people out. We counted every box on the real forms. In Washington the deadline is 30 days in most counties and 60 in some.
Snohomish County's deadline is August 25, and we are not selling you anything. We checked whether we could build it and we cannot, so here is how to file it yourself for free.
Your Ohio school district can only fight your appeal if you ask for $50,000 or more, quoted from the statute. Every other guide gives the warning without the line.
About 1 in 5 New Jersey homes can win a property tax appeal, and about 1 in 267 files, measured from 73,771 real sales across 302 towns.
What actually happens to Cook County property tax appeals, from all 351,196 residential cases the county decided in 2024.
The King County guide, with what a win is worth in your city and the finding that three in four wins came from the assessor agreeing rather than the board overruling.
The win rate in every Cook County township, measured from the county's own records. It runs from 9.2 percent in Palatine to 30.2 percent in North Chicago, so where you live changes your odds by about three times.
Somewhere else? Tell us your state on the check page and we will write to you the day we turn it on. We only switch a state on after reading its appeal rules and its board decisions, so that what we tell you is right rather than generic.
