How to Challenge Your Property Tax Assessment in Ohio

Ohio property owners have the right to appeal their county auditor's assessed value — but the window is short and the evidence requirements are specific. Here's what you need to know before the deadline.

Every few years, Ohio counties reassess residential properties to update their taxable values. If your county auditor's assessed value is higher than what your home would actually sell for in the current market, you may be paying more in property taxes than you should.

In Hamilton County, property owners can file a complaint with the Board of Revision between January 1 and March 31 of the year following a reappraisal or triennial update. Missing this window means waiting until the next cycle — so timing matters.

The most effective evidence you can bring to a Board of Revision hearing is a certified appraisal from a licensed Ohio appraiser. Unlike a Zillow estimate or a real estate agent's opinion of value, a USPAP-compliant appraisal is a formal, defensible document that the Board is required to consider seriously.

The appraisal needs to reflect the value of your property as of January 1 of the tax year in question — not today's value. This is called a retrospective appraisal, and it requires an appraiser who understands how to research and document market conditions from a specific point in the past.

It's also worth knowing what an appraiser does not do in this context. Apprsls prepares the appraisal report and can attend a hearing to defend it — but we do not file the complaint on your behalf, provide legal representation, or act as your advocate before the Board. For legal guidance, consult a property tax attorney.
