How Adams County Assesses Property

35%of market value

Assessed by: Adams County Auditor

Assessment cycle: triennial

Notices typically mailed: Spring (March-May)

In Adams County, properties are assessed at 35% of their market value, which is Ohio's statutory assessment ratio. If your home's market value is $97,600 (the county median), at Ohio's 35% assessment ratio your assessed value would be $34,160, resulting in approximately $896 in annual taxes at the county's effective rate of 0.92%. Ohio counties conduct a full sexennial reappraisal every six years and a triennial update at the three-year midpoint to ensure valuations reflect current market conditions.

The Appeal Process

Appeals are heard by the Board of Revision. The hearing is conducted before the Adams County Board of Revision, which consists of the County Auditor, County Treasurer, and President of the Board of Commissioners. You bear the burden of proof to demonstrate that your property's assessed value is incorrect, and you will have 5-15 minutes to present your evidence and answer questions.

Step 1: Review your property assessment notice and verify your property's current market value using the Adams County Auditor's property search tool at https://adamscountyauditor.org. Check that property details (square footage, bedrooms, bathrooms, lot size) are accurate, as errors can inflate your value.

How much can I save by appealing my property taxes in Adams County?
On the typical Adams County home valued near $97,600 at the county's effective tax rate of 0.92%, an over-assessment of even 10% means you are overpaying approximately $90 per year.

Studies show that about 25% of homes in America are unfairly over-assessed and pay an average of $1,346 too much in property taxes every year. The exact savings depend on how much your assessment is reduced and your property's specific tax rate based on your local school district and municipality. Successfully appealing your property taxes means those savings continue year after year until the next reappraisal cycle.
What evidence do I need for an Adams County property tax appeal?
For a successful property tax appeal in Adams County, you should gather recent comparable sales data showing 3-5 similar properties in your area that sold for less than your assessed value within the past 6-12 months. A professional appraisal report conducted by a licensed appraiser carries significant weight with the Board of Revision. Photographs documenting property condition, defects, or needed repairs can demonstrate why your home's value should be lower. Repair estimates from licensed contractors for any significant damage or deferred maintenance are also valuable evidence. Finally, verify that your property record card is accurate by checking the Adams County Auditor's website, as errors in square footage, bedroom count, or other features can artificially inflate your assessment.
Can I appeal my property taxes online in Adams County?
Adams County does not currently offer online electronic filing for property tax appeals.

However, you can download the DTE Form 1 from the Adams County Auditor's website at https://adamscountyauditor.org, and the county does offer online property search tools and GIS mapping to help you research your property information and find comparable sales data to support your appeal. For assistance or questions, call the Adams County Auditor at (937) 544-2364.
Is 2026 a reappraisal year in Adams County?
Yes, tax year 2025 (payable in 2026) is the first year of the triennial update cycle for Adams County, making 2026 a particularly important year to review your property assessment and consider filing an appeal.
