How Madison County Assesses Property

35%of market value

Assessed by: Madison County Auditor's Office

Assessment cycle: sexennial reappraisal with triennial update

Notices typically mailed: Spring (typically mid-April)

Ohio assesses all residential property at 35% of true market value, and Madison County follows this state mandate. For example, if your home's market value is $142,200 (the county median), at Ohio's 35% assessment ratio your assessed value would be $49,770, resulting in approximately $2,428 in annual taxes at the county's effective rate of 1.59%. This means you're only taxed on about one-third of your home's actual market value, but the local millage rates are applied to that assessed value to determine your final tax bill.

The Appeal Process

Appeals are heard by the Board of Revision. The Madison County Board of Revision consists of the County Auditor, County Treasurer, and a County Commissioner. Hearings are typically brief (5-15 minutes), and you'll present your evidence explaining why your property value should be reduced. Be aware that Ohio school districts can file counter-complaints within 30 days of your filing, potentially arguing for a higher value.

Step 1: Request an informal review with the Madison County Auditor's Office before filing a formal appeal. Contact the office at (740) 852-9717 to discuss your property valuation and potentially resolve the issue without a formal complaint.

Step 2: Gather evidence to support your appeal, including recent comparable sales within your neighborhood (sold within the past 12 months), photographs documenting property condition or defects, repair estimates for needed work, and a recent professional appraisal if available.

Step 3: Complete DTE Form 1 (Complaint Against the Valuation of Real Property) with your property information, parcel number, current auditor value, and your opinion of the correct market value. Include detailed justification for the requested reduction in the form's explanation section.

Step 4: File your completed DTE Form 1 with all supporting documentation to the Madison County Board of Revision between January 1 and March 31, 2026, ensuring it is received or postmarked by the March 31 deadline. Filing is free of charge.

Step 5: Attend the hearing before the Madison County Board of Revision when scheduled (you will receive written notice at least 10 days in advance). Present your evidence professionally, explain why your requested value reflects fair market conditions, and be prepared to answer questions from board members.

Step 6: Review the Board of Revision's written decision. If you disagree with their determination, you may appeal to the Ohio Board of Tax Appeals or Court of Common Pleas within 30 days of the decision letter by filing DTE Form 4 (Notice of Appeal).

How does Madison County assess property values?

Madison County follows Ohio's constitutional requirement to assess all property at 35% of true market value. The county completed a full sexennial reappraisal for tax year 2026, meaning every property was individually reappraised to reflect current market conditions. Assessment notices are typically mailed in spring (mid-April) each year. For example, a home with a market value of $142,200 would have an assessed value of $49,770 (35% of market value), and property taxes are calculated by applying local millage rates to this assessed value.

What happens at a Board of Revision hearing in Madison County?

At a Madison County Board of Revision hearing, you'll present your case to a three-member panel consisting of the County Auditor, County Treasurer, and a County Commissioner. You'll typically have 5-15 minutes to present your evidence explaining why your property value should be reduced. The board will review your comparable sales, photographs, appraisals, and other documentation, then ask questions about your property. Be aware that school districts in Ohio can file counter-complaints within 30 days of your filing, potentially arguing for a higher value, which could result in a two-sided hearing where you must defend against an increase.

What evidence do I need for a Madison County property tax appeal?

The strongest evidence for a Madison County appeal includes recent comparable sales of similar properties in your neighborhood that sold within the past 12 months for less than your assessed value. You should also provide photographs documenting any property defects, needed repairs, or unfavorable conditions that affect value. Repair estimates from licensed contractors for significant issues add credibility to your claim. If you purchased the property within the past year, bring your closing statement, this is often dispositive evidence if your purchase price is below the auditor's valuation. A professional appraisal can also support your case, though it's not required.

Can I appeal my Madison County property taxes online?

While many Ohio counties have implemented online filing systems for Board of Revision complaints, you should verify current filing options with the Madison County Auditor's Office at (740) 852-9717 or visit auditor.co.madison.oh.us. Traditional filing methods are always available: you can mail your completed DTE Form 1 and supporting documents to the Board of Revision at PO Box 47, London, OH 43140-0047, or deliver them in person to the Auditor's office at 1 N. Main Street, London, during business hours (Monday-Friday 8:00 AM-4:00 PM). Regardless of filing method, your complaint must be received or postmarked by March 31.

How much can I save by appealing my property taxes in Madison County?

Savings from a successful Madison County appeal vary based on your property's current valuation and the evidence you present. On a home assessed at the county median of $142,200, a successful 10% value reduction would save approximately $243 annually, while a 20% reduction would save $486 per year. These savings continue every year until the next reappraisal or update, typically for three years. Madison County completed a reappraisal in 2026, so any reduction granted would remain in effect through 2028. According to statewide data, successful Board of Revision complaints typically achieve 10-20% value reductions, though results depend on the strength of your evidence.
