Ohio Property Tax Assessment Appeal Letter Generator

If you believe your Ohio property has been over-assessed by your county auditor, you have a legal right to challenge that valuation. Ohio law allows property owners to file a formal complaint with the county Board of Revision (BOR) to seek a reduction in assessed value, which can significantly lower your annual property tax bill. A well-drafted appeal letter or complaint sets the stage for negotiation or hearing before the BOR. With Ohio's triennial reappraisal cycle and recent market volatility, many homeowners and commercial property owners are paying taxes based on inflated values. Understanding the statutory deadlines, evidentiary requirements, and procedural rules under Ohio Revised Code § 5715.19 is critical to preserving your right to a fair assessment and a potential refund.

Ohio property taxes are based on the assessed value of real property, which is set at 35% of the county auditor's appraised market value. Under Ohio Revised Code § 5715.19, any property owner, taxing authority, or other qualified party may file a complaint against the valuation of real property with the county Board of Revision (BOR). Complaints must be filed using DTE Form 1 between January 1 and March 31 of the tax year following the year being challenged (for example, a challenge to tax year 2024 values must be filed by March 31, 2025).

The BOR is composed of the county auditor, treasurer, and a member of the board of county commissioners (or their designees). The board reviews complaints, holds hearings, and issues decisions adjusting valuations where warranted. The property owner bears the burden of proving the auditor's valuation is incorrect, typically through evidence such as a recent arms-length sale, a professional appraisal, comparable sales data, or income/expense statements for commercial properties.

A significant 2022 amendment via House Bill 126 restricted school boards and other taxing authorities from filing valuation increase complaints unless the property recently sold, and limited their ability to appeal BOR decisions. This generally favors property owners pursuing reductions.

If the BOR's decision is unsatisfactory, owners may appeal to the Ohio Board of Tax Appeals (BTA) under R.C. 5717.01 within 30 days of the BOR decision, or alternatively to the county court of common pleas under R.C. 5717.05. Successful appeals result in retroactive reductions and refunds of overpaid taxes, often with statutory interest. Ohio's triennial update and sexennial reappraisal cycles mean valuations can be challenged each tax year following any reassessment.

While Ohio requires the formal DTE Form 1 to initiate a Board of Revision complaint, a well-crafted demand or appeal letter to the county auditor before or alongside the formal filing can be highly effective. Many Ohio counties allow informal value reviews where the auditor's office will reconsider a valuation without a full BOR hearing if the owner submits compelling evidence early.

Your letter should clearly identify the parcel by parcel number, address, and current assessed value. State the value you believe is correct and the specific basis for your opinion: a recent purchase price, a licensed appraisal report, comparable sales of similar properties in the same neighborhood, documented physical defects, or income/expense data demonstrating diminished commercial value. Attach supporting documentation such as MLS listings, photographs of damage or deferred maintenance, contractor repair estimates, or appraisal reports from a certified Ohio appraiser.

Reference Ohio Revised Code § 5715.19 and request both an informal review and confirmation of your right to formal BOR proceedings. Set a reasonable response deadline (typically 14 to 21 days) and indicate your intent to file a formal DTE Form 1 complaint by the March 31 statutory deadline if no agreement is reached.

A professional, evidence-based letter often prompts auditors to settle before hearing, especially when the supporting valuation evidence is strong. It also creates a documented record demonstrating good-faith effort, which can benefit you on appeal to the Board of Tax Appeals if necessary. Keep tone factual and non-confrontational—Ohio BORs respond best to objective evidence rather than complaints about tax burden.

Ohio BOR complaints must be filed on DTE Form 1 between January 1 and March 31 following the tax year. There is generally no filing fee for BOR complaints. Property owners may represent themselves; commercial entities valued over $50,000 in dispute typically must be represented by an attorney. BOR hearings are informal but recorded. Appeals to the Ohio Board of Tax Appeals (BTA) must be filed within 30 days of the BOR's mailed decision, with a $50 filing fee. Alternatively, appeals to the court of common pleas follow similar timing under R.C. 5717.05. Note that under R.C. 5715.19(A)(2), only one complaint per triennial period is generally permitted unless specific exceptions apply, such as a substantial change in property condition.
