Filing a property tax valuation complaint in Ohio is not complicated procedurally, but a surprising number of otherwise valid complaints fail for avoidable reasons. Here are the ten mistakes we see most often.

●       1. Missing the March 31 filing deadline. There is no informal grace period.

●       2. Filing with no supporting evidence beyond general frustration that taxes are too high. Boards need comparable sales, an appraisal, or a recent purchase price.

●       3. Assuming a mailed valuation notice is final and cannot be challenged.

●       4. Relying on what you paid decades ago instead of current market evidence.

●       5. Not realizing a school board or other party can file a counter complaint seeking a higher value if a recent sale supports it.

●       6. Overlooking the one complaint per interim period limit and filing a second complaint that gets dismissed outright.

●       7. Appearing at a Board of Revision hearing without understanding it is a sworn, evidence based proceeding, not an informal conversation.

●       8. Failing to document an arm's length sale properly when relying on it as evidence.

●       9. Waiting for a countywide reappraisal or update year when a qualifying event, a casualty loss, new construction, or an occupancy change, already allows a complaint in an off year.

●       10. Not appealing further to the Ohio Board of Tax Appeals when a Board of Revision decision is clearly wrong on the evidence.

Practical takeaway

Most of these mistakes come down to treating the process as informal when it is actually evidence driven and deadline bound. Come prepared with real comparables or an appraisal, know your county's filing deadline, and do not assume this is your only shot if the first attempt is dismissed on a technicality.
