How Shelby County Assesses Property

35%of market value

Assessed by: Shelby County Auditor's Office

Assessment cycle: Sexennial reappraisal (every 6 years) with triennial update (every 3 years)

Notices typically mailed: Mid to late summer in reappraisal and update years

Ohio law requires all property to be assessed at 35% of its true market value. For example, if your home's market value is $208,100 (the county median), your assessed value would be $72,835 (208,100 × 0.35). At Shelby County's effective tax rate of 1.11%, this would result in approximately $808 in annual property taxes. This assessment ratio is set by the Ohio Tax Commissioner and applies uniformly across all 88 Ohio counties.

The Appeal Process

Appeals are heard by the Board of Revision. The normal procedure in Shelby County is for the Board of Revision or its designated representatives to visit your property and conduct a physical inspection after receiving your complaint. At the hearing, you will present your evidence to the Board, which consists of the County Auditor, County Treasurer, and a County Commissioner member.

Step 1: Gather evidence supporting your claim that the assessed value is incorrect, including recent comparable sales from the past 12 months, a professional appraisal, photographs of property condition, or documentation of needed repairs.

Step 2: Contact the Shelby County Auditor's Office at 937-498-7202 for an informal discussion about your property valuation before filing a formal complaint. This optional step can help clarify whether you have grounds for an appeal.

Step 3: Obtain and complete DTE Form 1 (Complaint Against the Valuation of Real Property) and the residential property questionnaire. Forms are available on the county website, at the Auditor's Office, or by calling 937-498-7202.

Step 4: File your complaint between January 1 and March 31, 2027 (for 2026 tax year) with all supporting documentation. Include copies of comparable sales, appraisals, photos, and the completed property questionnaire. There is no filing fee.

Step 5: The Board of Revision will schedule a hearing and typically conduct a physical inspection of your property. You will have 5-15 minutes to present your evidence at the hearing. The Board (comprised of the County Auditor, County Treasurer, and a County Commissioner) will issue a decision.

Step 6: If you disagree with the Board of Revision's decision, you may appeal to the Ohio Board of Tax Appeals or Court of Common Pleas within 30 days of receiving the Board's decision notice by filing DTE Form 4.

The mailbox rule applies, meaning if you mail your complaint, the USPS postmark date is treated as the filing date.

Private meter postmarks are not valid for establishing the filing date.

How do I file a property tax appeal in Shelby County?

File your appeal using DTE Form 1 (Complaint Against the Valuation of Real Property), available from the Auditor's Office or their website. Submit the completed form with supporting evidence to: Shelby County Auditor, County Annex Building, 3rd Floor, 129 E Court Street, Sidney, OH 45365. You can file by mail (postmarked by March 31) or in person during office hours (Monday-Thursday 8:30 AM-4:30 PM, Friday 8:30 AM-Noon). Before filing, you may call 937-498-7202 for an informal discussion about your valuation. There is no filing fee.

What is the homestead exemption worth in Shelby County?

The standard homestead exemption for seniors (65+), disabled persons, and surviving spouses reduces the taxable value by up to $29,000 of market value, saving approximately $336 annually at Shelby County's effective tax rate. Disabled veterans receive an enhanced exemption of up to $50,000 of market value (approximately $580 annual savings) with no income restrictions. New applicants since 2014 must meet Ohio Adjusted Gross Income thresholds to qualify for the standard exemption. You must apply by December 31 of the year for which you're seeking the reduction.

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

After you file your complaint, the normal procedure in Shelby County is for the Board of Revision or its designated representatives to visit your property and conduct a physical inspection. At the hearing, you'll have approximately 5-15 minutes to present your evidence to the Board, which consists of the County Auditor, County Treasurer, and a County Commissioner. You should bring comparable sales data, appraisals, photographs, and repair estimates to support your claim. The Board will review your evidence and issue a written decision. If you disagree with the decision, you have 30 days to appeal to the Ohio Board of Tax Appeals or Court of Common Pleas.

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

Your potential savings depend on how much your property is overvalued and the county's effective tax rate of 1.11%. For example, if you successfully reduce your home's market value from $250,000 to $225,000 (a $25,000 reduction), your assessed value would decrease by $8,750 (35% assessment ratio). This would save approximately $97 annually in property taxes. Even with Ohio's HB 920 reduction factors, lowering your assessed value saves money on inside millage, bonds, and future voted levies. The median overassessment in Ohio is approximately $1,346 annually.

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

The strongest evidence includes recent comparable sales (sold within the past 12 months) of similar properties in your neighborhood showing lower values, a professional appraisal demonstrating your home is worth less than the assessed value, and photographs documenting property condition or defects. You should also include repair estimates for needed work, the completed residential property questionnaire from the Auditor's Office, and any documentation of factors negatively affecting your property's value. Submit copies of all supporting documents along with your DTE Form 1 complaint. The Board of Revision will typically conduct a physical inspection of your property as part of the review process.

How often are properties reappraised in Shelby County?

Ohio law requires Shelby County to conduct a full sexennial reappraisal every six years, which includes physical inspections and updated valuations based on market conditions as of January 1. Three years after each reappraisal, the county must perform a triennial update that adjusts values based on sales trends and market data without physical property inspections. The county follows Ohio's staggered reappraisal schedule assigned by the state. Individual properties may be reassessed more frequently if improvements are made or if you file a successful appeal. Assessment notices are typically mailed in mid to late summer during reappraisal and update years.

Can school districts challenge my property tax appeal in Shelby County?

Yes, Ohio has a counter-complaint mechanism that allows school districts to challenge your appeal. When you file a DTE Form 1 complaint seeking a lower valuation, the school district where your property is located has the right to file a counter-complaint within 30 days, arguing that the value should actually be higher than the Auditor's current assessment. This is unique to Ohio and means filing a property tax appeal carries some risk. However, your original complaint can only result in a lower or unchanged value, only the school district's counter-complaint could increase it. This is an important consideration when deciding whether to appeal.
