Ohio property owners who believe their property has been over‑valued for tax purposes have a limited window each year to challenge that valuation. The statewide deadline to file a property tax valuation appeal is March 31, and this deadline applies in every Ohio county.
A property valuation appeal is not a challenge to the tax rate itself — it is a challenge to the assessed value that determines how much tax you pay. If the county’s valuation does not reflect current market conditions, filing an appeal with the Board of Revision may result in a lower taxable value. A successful reduction can lead to a refund, credit, or lower payments going forward.
For many property owners, especially those who have seen significant increases in recent valuation cycles, this process is an important tool for ensuring fair taxation. Because property values typically remain in place for a three‑year cycle, filing before the March 31 deadline can help lock in savings for multiple years.
At Critchfield, we assist residential, agricultural, commercial, and industrial property owners in reviewing their valuations, gathering the right supporting evidence, and filing appeals with the appropriate county Board of Revision. Our team works with clients throughout the region to help ensure their property is valued accurately and fairly.
