Home / Ohio
Ohio works and looks underserved.
We check individual addresses here. There’s no value cap, because HB 920 rolls back district rates rather than values. Sale prices are public. And the market looks thin: Cuyahoga County took only 9,600 complaints for a county of 1.2 million people. One real risk is that school districts can counter-file against a reduction.
So Ohio decides these on market value, which means the evidence is recent sales of genuinely comparable homes. What really matters is whether that whole set of sales sits below your assessed value. If they bracket your assessment instead of falling under it, boards usually side with the assessor, because nothing's been clearly disproved.
Now a few things lose almost everywhere. Comparing your assessment to a neighbor's assessment usually doesn't count where the argument's market value. One sale on its own can pretty easily be dismissed as an outlier. And the size of your increase, or the size of your bill, isn't really evidence about what your home's worth.
January 1 to March 31 every year. The window reopens January 1, 2027.
Miss it and you generally wait a year, so honestly the date matters more than the paperwork does.
And wherever you are, the single most useful thing you can actually do today is go find your assessment notice and read the date printed on it. That's what starts your clock, it's usually a much shorter window than people expect, and there's no getting it back once it's gone.
Our free check works for Cuyahoga County, including Cleveland, Franklin County, including Columbus, and Summit County, including Akron, where we've also measured how sales compare with the new 2026 values in every town. We've also written about when a school district can fight your appeal and whether a big reappraisal raises your bill.
First, look up your own record. In Ohio it's the county auditor who values your home, and their website shows the value and the details behind it. Values get reset every six years, and there's an update at the three year mark.
Next, know where to file. You file a complaint with your county's Board of Revision between January 1 and March 31. Most counties'll accept it online or by mail on the state's form, and filing's free.
Then bring the evidence that wins here. Ohio decides these on market value, so the evidence is recent sales of genuinely similar homes, or your own recent purchase price. But if you're asking for a change of $50,000 or more in value, your school district can file its own complaint to keep the value up, so it's worth knowing that before you file.
Also, check your exemptions. If you're 65 or older, or disabled, and your income's under the limit, the homestead exemption takes $29,000 off your home's value for 2026, with a $41,000 income limit. Every owner-occupied home gets a credit on part of the bill as well, so check that it's on yours. You apply with your county auditor.
So type your address into our free check and we'll read the county's own records, work out whether the evidence actually supports an appeal, and tell you straight. Most people who use it get told not to bother, which is the point.
We've screened all fifty states and DC on the same two questions. Does winning a lower market value actually lower your bill, or is there a cap sitting in between? And can you even put the evidence together from public records?
This comes from our own fifty-state screen, where we checked each state's cap, whether sale prices are public, whether there's an argument based on assessed values, and how many appeals actually get filed. Where we've quoted an appeal count, it's from the state or county that published it. If you spot an error, please write to hello@propertytaxbuddy.com and we'll correct it and say what changed.
