Understanding Ohio's Assessment Ratio

35%
appraised at 100% of true value, taxed on 35% of it

Ohio uses a 35% assessment ratio, meaning your assessed value is set at 35% of your property's estimated market value.

To find your implied market value: Divide your assessed value by 0.35.
Example: Assessed value of $75,180 ÷ 0.35 = $214,800 implied market value

⚠ Common Mistake: Never compare your assessed value directly to comparable sale prices in Ohio. Always convert to implied market value first.

Ohio's assessment ratio study

How closely Ohio assessors' values actually track real sale prices — and whether you can use that in an appeal.

Usable as supporting evidenceLatest study: 2026

Sales-assessment ratio analysis (Residential Sales Data by County and Jurisdiction)

File a DTE Form 1 complaint with the county Board of Revision arguing true value, citing the DOT jurisdiction median to show the auditor's values overshoot the 92–94% target; any reduction then flows through at 35%. HB 124 (effective March 2026) made the underlying sales sample a county-generated, appealable record — so it is now discoverable and contestable in a way it was not before.

Sales-sample source changed; new appeal rights

The Tax Commissioner must now use the county auditor's own sample of arm's-length sales from the previous three years when testing county values, rather than selecting a sample independently — and must appeal the county's sample to the Board of Tax Appeals if he considers it unreasonable. Taxpayers gain the right to appeal Department of Taxation corrections and auditor-sample orders to the Board of Tax Appeals and the Ohio Supreme Court.

Supplemental, Escape & Corrected Bills in Ohio

Ohio has no supplemental or prorated mid-year tax bill - new construction is simply valued as it stands each January 1 lien date and appears on the next bill (paid in arrears). Extra charges arise only as 'omitted' back taxes (up to 5 years, no interest) or clerical-error corrections, and value disputes go to the county Board of Revision by March 31.

Omitted Property / Omitted Back Taxes

County auditor discovers a building, structure, or parcel omitted from the real property list; auditor adds it and computes simple back taxes for the omitted years.

Appeal window: No dedicated statutory window from the omitted-tax notice; the owner's remedy is a Board of Revision complaint against the valuation (DTE Form 1) filed by March 31 of the year following the tax year, and/or application to the auditor for correction.

Clerical Error Correction / Refund

Auditor discovers clerical errors in owner name, valuation, description, or quantity on the tax list; corrections (and refunds of resulting overpayments) processed administratively.

Appeal window: Refund applications for clerical-error overpayments generally reach back 5 years (R.C. 319.36/5715.22 procedures); disputes over value still go to the BOR by March 31.
