Generate an Ohio property tax abatement request letter. Challenge over-assessments under R.C. 5715.19 with deadlines, statutes, and county BOR procedures.
Generate My Letter — $19If you own property in Ohio and believe the county auditor has overvalued it, you have a legal right to challenge that assessment and request an abatement or reduction. Ohio law gives every property owner a structured process to contest the assessed value of real property through the county Board of Revision. Filing a well-drafted abatement request letter is often the first and most effective step before formal complaint hearings. Because Ohio's tax cycle and filing windows are strict, missing a deadline can cost you a full year of overpayment. This page explains how Ohio's property tax appeal laws work, what your letter should include, and how to position your request for the best chance of a reduction in valuation and a refund of any overpaid amounts.
Ohio property taxes are based on the county auditor's appraised value of your real estate, with assessed value set at 35% of true market value under R.C. 5715.01. Each county reappraises property every six years and updates values every three years. If you believe the appraised value exceeds the actual fair market value of your home or commercial property, Ohio Revised Code § 5715.19 provides the right to file a Complaint Against the Valuation of Real Property (Form DTE 1) with the county Board of Revision (BOR).
The BOR is a three-member body consisting of the county auditor, treasurer, and a member of the board of county commissioners (or their designees). It hears evidence on whether the property's value should be increased, decreased, or kept the same. Owners may submit appraisals, recent sale documents, photographs of property defects, comparable sales, and income/expense data for income-producing property.
Under R.C. 5715.19(A)(1), a complaint must be filed between January 1 and March 31 of the year following the tax year being challenged. Only one complaint per triennial cycle is generally permitted unless an exception applies, such as a substantial improvement, casualty loss, or change of ownership reflecting fair market value.
If the BOR's decision is unfavorable, the owner may appeal to the Ohio Board of Tax Appeals under R.C. 5717.01 within 30 days, or to the court of common pleas under R.C. 5717.05. Successful challenges result in a corrected valuation and refund of overpaid taxes with interest, pursuant to R.C. 5715.22. Recent changes through House Bill 126 (effective 2022) significantly limited school boards' ability to file counter-complaints, generally favoring property owners who initiate appeals.
While Ohio's formal challenge process requires filing Form DTE 1, sending a written abatement request letter to the county auditor before or alongside the complaint can streamline resolution. Many Ohio county auditors have informal review programs where overvaluations are corrected administratively without a full BOR hearing, especially when clear evidence of error exists.
An effective Ohio abatement request letter should identify the parcel by parcel number, owner name, and property address, and state the current appraised and assessed values on record. It should then specify the value the owner believes is correct and provide supporting evidence: a recent purchase price (if arm's-length within the past 24 months), a licensed appraisal, comparable sales of similar properties, photographs documenting condition issues, contractor estimates for needed repairs, or rental income data for investment property.
The letter should reference R.C. 5715.19 and explicitly request either an informal correction or scheduling of a BOR hearing. It should also request a refund of overpaid taxes under R.C. 5715.22 if the value is corrected retroactively. Sending the letter via certified mail creates a record of timely submission. Including a clear deadline for response (commonly 30 days) signals seriousness and preserves your ability to escalate to the Board of Tax Appeals if ignored. A professional, fact-based letter often resolves disputes faster than litigation, particularly for residential properties with straightforward valuation errors.
Filing a DTE 1 complaint with the county Board of Revision is free in Ohio—there is no filing fee at the BOR level. Appeals to the Ohio Board of Tax Appeals also carry no filing fee, while appeals to the court of common pleas require standard civil filing fees that vary by county (generally $200–$350). Hearings before the BOR are informal but recorded, and owners may represent themselves or hire counsel. Property owners are not required to be lawyers to file. Ohio's small claims court (limit $6,000) is generally not used for valuation disputes—those must go through the BOR system. Strict adherence to the January 1–March 31 filing window is critical; late complaints are dismissed for lack of jurisdiction.
Property tax in Ohio is governed by the Ohio Revised Code Title 57 (Taxation) — real property valuation, complaints, and appeals (Chapters 5715, 5717, 5721) (Ohio Rev. Code §§ 5715.01, 5715.19, 5717.01; Ohio Admin. Code 5703-25-05). Assessment cycle: Six-year cycle: a full reappraisal every 6 years with a triennial update at the 3-year midpoint. Property is valued as of the tax lien date (January 1). Assessed value: 35% — the taxable (assessed) value of each parcel is 35 percent of true value in money (ORC § 5715.01; OAC 5703-25-05).
County Board of Revision (first level) and the Ohio Board of Tax Appeals (state administrative appeal); county auditors administer valuations. The Ohio Department of Taxation oversees property tax administration statewide. The window to act is short — march 31 of the following tax year to file a valuation complaint (DTE Form 1) with the county Board of Revision — a firm statutory cutoff. To appeal a Board of Revision decision to the Board of Tax Appeals, a notice of appeal must be filed within 30 days after the BOR's decision is mailed (ORC 5717.01).
A recent change to watch: As of 2025-2026, House Bill 493 proposes ending the sale of delinquent tax liens to third parties, and the Ohio Senate has advanced a Homestead Exemption expansion. (Reform proposals — not yet enacted as of 2026-07-22.).
First-level appeal: County Board of Revision (BOR) — file a DTE Form 1 complaint against valuation. The BOR is composed of the county auditor, county treasurer, and a county commissioner. An informal review with the County Auditor is often available first.
Exemptions to claim: Homestead Exemption for seniors (65+) and permanently disabled homeowners: exempts the first $26,200 of home value (income-tested; OAGI $38,600 or less for first-time qualifiers in 2024). Enhanced Homestead for disabled veterans (100% service-connected): exempts the first $52,300 of value. Surviving-spouse exemption for spouses of public safety personnel killed in the line of duty.
Appeal deadline: March 31 of the following tax year to file a valuation complaint (DTE Form 1) with the county Board of Revision — a firm statutory cutoff. To appeal a Board of Revision decision to the Board of Tax Appeals, a notice of appeal must be filed within 30 days after the BOR's decision is mailed (ORC 5717.01).
Next-level appeal: Ohio Board of Tax Appeals (BTA) under ORC 5717.01, appealed within 30 days of the BOR decision mailing. Further review may be taken to the Court of Appeals / Ohio Supreme Court.
Grounds you can raise: The appraised/true (market) value assigned by the county auditor is incorrect (too high or too low). You cannot challenge the 35% assessment ratio itself — only the underlying true value.
Evidence that works: Recent sale price of the subject property, comparable sales, independent appraisals, income/expense data for income-producing property, and photographs of condition/defects.
How your value is assessed: 35% — the taxable (assessed) value of each parcel is 35 percent of true value in money (ORC § 5715.01; OAC 5703-25-05).
The hearing: Administrative hearing before the county Board of Revision where the owner and auditor present evidence; the BOR issues a written decision. BTA appeals are heard de novo.
First, county Board of Revision (BOR) — file a DTE Form 1 complaint against valuation. The BOR is composed of the county auditor, county treasurer, and a county commissioner. An informal review with the County Auditor is often available first.
If that fails, ohio Board of Tax Appeals (BTA) under ORC 5717.01, appealed within 30 days of the BOR decision mailing. Further review may be taken to the Court of Appeals / Ohio Supreme Court.
Mind the deadline: march 31 of the following tax year to file a valuation complaint (DTE Form 1) with the county Board of Revision — a firm statutory cutoff. To appeal a Board of Revision decision to the Board of Tax Appeals, a notice of appeal must be filed within 30 days after the BOR's decision is mailed (ORC 5717.01).
