Clark County Property Tax Appeal, Ohio

Travis BunnTravis Bunn·Updated July 25, 2026

Clark County is located in west-central Ohio with a population of approximately 135,000 residents as of 2024. Springfield, the county seat and largest city with about 58,000 residents, anchors the county alongside smaller communities like New Carlisle. Property tax appeals matter significantly in Clark County because property values increased by 32% in 2026, placing additional financial pressure on homeowners. The county's median effective property tax rate of 1.32% to 1.69% is higher than the national median of 0.99%, though the median annual tax bill remains below national averages due to the county's relatively modest home values.

How Clark County Assesses Property

35%of market value

Assessed by: Clark County Auditor's Office

Assessment cycle: triennial

Notices typically mailed: Spring (April-May)

Clark County assesses all real property at 35% of true market value, as required by the Ohio Constitution. This assessed value is then multiplied by local millage rates to determine your tax bill. For example: If your home's market value is $145,000 (the county median), at Ohio's 35% assessment ratio your assessed value would be $50,750, resulting in approximately $1,914 in annual taxes at the county's effective rate of 1.32%.

The Appeal Process

Appeals are heard by the Board of Revision. Once your complaint is filed, the Board of Revision will schedule a hearing. The Board hears complaints about property values, not tax bills. You'll typically have 5-15 minutes to present your evidence, so organize your materials clearly and focus on facts about market value.

1

Step 1: Request an informal review with the Clark County Auditor's appraisal team. These sessions are typically held in September and October of reappraisal years and provide an opportunity to resolve valuation concerns before filing a formal appeal.

2

Step 2: If the informal review does not resolve your concerns, obtain DTE Form 1 from the Clark County Auditor's website or office. The form is available during the January 1 - March 31 filing period.

3

Step 3: Complete DTE Form 1 with your property information, current assessed value, and your opinion of the correct market value. Gather supporting evidence including recent comparable sales, a recent appraisal, purchase documentation, photographs of property defects, or repair estimates.

4

Step 4: File your completed DTE Form 1 and all supporting documentation with the Clark County Board of Revision by March 31. You can mail it to the Auditor's Office at 31 North Limestone Street, Springfield, OH 45502, or deliver it in person during business hours.

5

Step 5: The Board of Revision will schedule a hearing to review your complaint. The Board consists of the County Auditor, County Treasurer, and a County Commissioner. Present your evidence clearly and be prepared to answer questions about your property's value.

6

Step 6: Receive the Board of Revision's decision by mail. If you disagree with the decision, you have 30 days from the decision date to appeal to the Ohio Board of Tax Appeals or the Court of Common Pleas by filing DTE Form 4.

7

Step 7: If necessary, pursue further appeals through the Ohio Board of Tax Appeals or Common Pleas Court. Note that school districts have the right to file counter-complaints within 30 days of your initial filing, potentially arguing for a higher valuation.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Clark County?
The deadline to file a property tax appeal in Clark County is March 31, 2026 for the 2025 tax year. The filing window runs from January 1 through March 31, and this deadline is strictly enforced with no extensions permitted. If you mail your appeal, it must be received by March 31 or bear a USPS postmark of March 31 or earlier. Missing this deadline means you'll have to wait another full year to challenge your assessment and will be locked into paying taxes on the current valuation.
How do I file a property tax appeal in Clark County?
To file a property tax appeal in Clark County, you must complete DTE Form 1 (Complaint Against the Valuation of Real Property) and submit it to the Board of Revision between January 1 and March 31. You can obtain the form from the Clark County Auditor's website at clarkcountyauditor.org or in person at the Auditor's Office. Include all supporting evidence such as comparable sales, appraisals, or photos with your filing. Submit the completed form by mail to 31 North Limestone Street, Springfield, OH 45502, or deliver it in person during business hours Monday through Friday, 8:00 AM to 4:30 PM.
What is the homestead exemption worth in Clark County?
The standard homestead exemption in Clark County exempts $29,000 of your home's market value from taxation for 2026, which typically saves homeowners $300-$400 annually depending on local tax rates. If you're a disabled veteran with a 100% VA disability rating, you qualify for the enhanced exemption of $58,000 with no income limit, potentially saving $600-$800 per year. To qualify for the standard exemption, you must be age 65 or older or permanently disabled, with Modified Ohio Adjusted Gross Income of $41,000 or less. Apply using Form DTE 105A for the standard exemption or Form DTE 105I for the disabled veteran exemption.
Should I request an informal review before filing a formal appeal in Clark County?
Yes, requesting an informal review with the Clark County Auditor's appraisal team is highly recommended before filing a formal Board of Revision appeal. These informal hearings are typically held in September and October of reappraisal years and give you the opportunity to discuss your concerns directly with the appraisers who valued your property. Many valuation disputes are resolved at this stage without needing to file a formal appeal. If the informal review doesn't resolve your concern, you can still file DTE Form 1 with the Board of Revision between January 1 and March 31.
How much can I save by appealing my property taxes in Clark County?
The savings from a successful property tax appeal in Clark County depend on how much your assessment is reduced and your local tax rate. With the county's effective rate of approximately 1.32%, a reduction of $10,000 in market value translates to about $46 in annual tax savings (based on the 35% assessment ratio). If your home is overvalued by 10% on a median-value home of $145,000, that's a $14,500 overassessment, which could save you approximately $67 per year, or $670 over a typical 10-year period. Homes with larger overassessments or higher market values will see proportionally greater savings. National statistics suggest that about 25% of homes are overassessed.
What evidence do I need for a successful property tax appeal in Clark County?
The strongest evidence for a Clark County property tax appeal includes recent comparable sales of similar homes in your neighborhood that sold for less than your assessed value. If you purchased your home within the past 12 months, your settlement statement showing the actual sale price is often dispositive evidence that the Board of Revision will accept. Other valuable evidence includes a recent independent appraisal (less than 12 months old), photographs documenting property defects or needed repairs, repair estimates from contractors, and documentation proving that property details in county records are incorrect. The Board of Revision focuses on market value, so your evidence should demonstrate what your property would actually sell for in the current market.
Can the school district challenge my property tax appeal in Clark County?
Yes, Ohio law gives school districts the right to file a counter-complaint within 30 days of your initial Board of Revision filing. When you file DTE Form 1 seeking a lower valuation, the school district where your property is located can argue that your value should actually be higher than the current assessment. This is one of the most consequential counter-complaint mechanisms in the country and means filing an appeal carries some risk. However, if you have strong evidence that your property is overvalued, the benefits of a successful appeal typically outweigh this risk. The Board of Revision will consider evidence from both sides and make a determination based on the property's true market value.
How does Ohio's 35% assessment ratio affect my Clark County property taxes?
Ohio law requires all real property to be assessed at 35% of true market value before applying local tax rates. This means if your home has a market value of $150,000, only $52,500 (35% of $150,000) is subject to taxation. At Clark County's median effective rate of 1.32%, you would pay approximately $1,980 in annual property taxes. Understanding this ratio is important for appeals because you need to know both your property's true market value and how it translates to assessed value. When filing DTE Form 1, you'll state your opinion of the property's full market value, and the Board of Revision will determine the correct 100% market value, which is then automatically assessed at 35% for tax purposes.
