How Hamilton County Assesses Property

35%of market value

Assessed by: Hamilton County Auditor's Office

Assessment cycle: triennial

Notices typically mailed: middle of April

In Ohio, residents pay real estate taxes on the assessed value, which is 35% of the fair market or appraised value. For instance, if your home has a market value of $200,000, the assessed value will be $70,000. With a median home value of $205,000, Hamilton County property owners typically pay around $3,297 annually in property taxes. If your home's market value is $205,000, at Ohio's 35% assessment ratio your assessed value would be $71,750, resulting in approximately $3,297 in annual taxes at the county's effective rate of 2.32%.

The Appeal Process

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

Board of Revision hearings last approximately 15 minutes. It's important to understand that the Board decides cases about property VALUE, not taxes, and the burden of proof falls on the complainant to justify a change in value. Oral testimony by the complainant, a qualified real estate expert such as a licensed real estate appraiser, and the Auditor's real estate staff are acceptable. In some cases, the Board may conclude based on timely submitted evidence that your requested value is justified and your presence is not required. The Board will notify you no less than 10 days prior to the hearing date if your presence is required.

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

With Hamilton County's median annual tax bill of $3,119, which is $719 higher than the national median of $2,400, even a modest reduction in your property value could result in significant savings. With a median home value of $205,000, property owners typically pay around $3,297 annually in property taxes. If the Board of Revision reduces your property's value, the new value will generally apply through the end of the current three-year period. By seeking a single value reduction, property owners can potentially save money on their taxes for several years. The exact amount depends on your property's current assessment and the evidence you present to support a lower value.

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

It is not enough to file a complaint and not provide evidence to back up your requested value. The Board weighs all properly submitted evidence in determining market value. You must provide evidence, such as a recent appraisal or sales of comparable homes. Oral testimony by the complainant, a qualified real estate expert such as a licensed real estate appraiser, and the Auditor's real estate staff are acceptable. The Board considers evidence based on January 1st (the tax lien date) of the filing year. Strong evidence includes recent sales data from your neighborhood, professional appraisals, and documentation of any property defects or conditions affecting value.

Can I appeal my Hamilton County property tax assessment every year?

Yes, you can file a property tax appeal annually in Hamilton County between January 1 and March 31. The Hamilton County Auditor performs a full reappraisal of each property every six years, with the last reappraisal occurring in 2023 and the next scheduled for 2029. County auditors perform a revaluation at the midpoint of each six-year appraisal period. The midpoint revaluations don't include a physical inspection of the property and only consider general market conditions. Of the approximate 353,600 parcels in the County, only 4,407 had complaints filed on them (merely 1.25%) in 2018. Even if your value was reduced in a previous year, you may need to file again if market conditions change.
