Taxation and Finance Ohio 3 Minutes Read · published February 21, 2026 Flag of Ohio

Dayton, Ohio property owners can challenge their real property assessments through the county process that reviews valuations and classifications. This guide explains the practical steps to evaluate your assessment, gather evidence, file a complaint with the county Board of Revision, attend a hearing, and pursue further appeals if necessary. Start by confirming the assessed value and classification on your Montgomery County property record and collect recent sale comparables, photographs, and inspection reports to support a reduction. Deadlines and exact filing requirements are controlled at the county level, so consult the county auditor for forms and local instructions.[1]

Understanding the Review Process

In Dayton, assessments for property tax are prepared and maintained at the county level. The typical review path is: review the auditor record, file a complaint with the County Board of Revision, attend an evidentiary hearing, and, if needed, appeal the Board of Revision decision to the next tribunal allowed by Ohio law. Evidence should focus on market value, physical condition, and correct classification or exemptions.

Start early: gather sales, photos, and inspection reports before filing.

Penalties & Enforcement

Appealing an assessment is not a criminal enforcement action, and typical penalties for filing an appeal are not applicable. Monetary penalties or fines for the act of appealing are not applicable; however, failure to pay taxes based on the assessed valuation may result in standard collection actions described by county rules.

  • Fine amounts: not specified on the cited page.
  • Escalation for nonpayment: standard tax collection and interest rules apply; specific amounts and interest rates are not specified on the cited page.
  • Non-monetary sanctions: tax lien, foreclosure of tax liens, and collection procedures as provided by county and state law (not specified in detail on the cited page).
  • Enforcer and contacts: Montgomery County Auditor and the County Board of Revision handle valuation and classification reviews; contact links are in Resources below.
  • Appeal routes and time limits: the County Board of Revision handles initial complaints; further appeals follow state procedures—specific filing deadlines and statutory references are not fully specified on the cited page.
  • Defences/discretion: common defences include demonstrating lower market value, incorrect property classification, or documented physical defects; certain exemptions or abatements may apply depending on eligibility.
If you miss a filing deadline you may lose the right to a review.

Check the county auditor or Board of Revision page for the current "Complaint Against the Valuation or Classification" form, submission instructions, and any local requirements.[1]

How to Prepare Evidence
