Rate Breakdown

Property taxes in Delaware County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Delaware County

Property taxes in Delaware County, Ohio, are based on the fair market value of the real estate, which is determined by the County Auditor. Ohio utilizes a periodic assessment cycle where properties are appraised to ensure values reflect current market trends. Once the market value is established, the Auditor applies an assessment ratio to determine the taxable value.

The actual amount of tax owed is calculated using millage rates. A "mill" represents one dollar of tax for every $1,000 of assessed property value. These rates are determined by local taxing districts, including the county, city, village, and school districts. Because millage rates vary by specific location and voter-approved levies, your total tax burden depends heavily on your property's specific taxing jurisdiction.

Available Exemptions

Homeowners in Delaware County may be eligible for various tax reductions to lower their overall liability. Common exemptions in Ohio include:

• Homestead Exemption: Designed to provide relief to homeowners who occupy their property as a primary residence.
• Senior Citizen Reductions: Specific tax credits or reductions may be available for residents aged 65 and older to help maintain homeownership on a fixed income.
• Disability Exemptions: Reductions are available for individuals with qualifying permanent disabilities.
• Veteran Exemptions: Certain disabled veterans may be eligible for significant property tax reductions or full exemptions depending on their service-connected disability rating.

Payment Schedule & Deadlines

Property taxes in Delaware County are typically billed in two semi-annual installments. The first half is generally due in the fall, and the second half is due in the spring. It is critical to monitor the mail for official notices from the County Treasurer.

Payments can be made online, by mail, or in person at the Treasurer's office. If a payment is missed, the county applies interest penalties to the outstanding balance. Failure to pay taxes over an extended period may eventually lead to the property being listed for a tax foreclosure sale.

Appealing Your Assessment

If you believe your property has been overvalued by the County Auditor, you have the right to appeal the assessment. The process typically begins with a request for an informal review with the Auditor's office, where you can provide evidence—such as recent comparable sales or an independent appraisal—to support a lower valuation.

If an agreement cannot be reached informally, you may file a formal complaint with the Ohio Board of Tax Review (OBTR). There are strict statutory deadlines for filing appeals, usually occurring shortly after the new valuation notices are mailed; missing these windows typically forfeits your right to appeal for that tax cycle.
