How Property Tax Works

Clinton County, Ohio operates under a property tax system that funds essential local services including schools, fire protection, emergency medical services, libraries, and county operations. Property taxes are administered by the Clinton County Auditor's Office and collected twice annually. The county's property tax rates vary by location within the county due to different combinations of taxing districts including school districts, townships, municipalities, and special service districts.

The effective property tax rate in Clinton County typically ranges from approximately 2.0% to 3.5% of assessed value, depending on your specific location and the taxing districts that serve your property. Ohio assesses property at 35% of fair market value, and Clinton County's base levy rate has been reduced to 2.5 mills for the 2025 tax year, down from the previous 3.0 mills. However, your total tax bill will include additional levies from school districts, townships, municipalities, and other special districts that serve your property location.

Section 4

Supplemental Tax Bills

Supplemental taxes in Clinton County are additional property tax bills issued when there are changes to property ownership, new construction, or improvements that increase assessed value during the tax year. These occur most commonly when property changes hands and is reassessed at current market value, or when new construction or major improvements are completed after the annual assessment date.

Supplemental taxes are calculated by taking the difference between the new assessed value and the previous assessed value, multiplying by 35% (Ohio's assessment ratio), then applying the applicable tax rate for the remaining months in the tax year. For example, if a property's assessed value increases by $50,000 in July due to new construction, the supplemental tax would be calculated on $17,500 (35% of $50,000) at your local tax rate, prorated for the remaining months of the tax year. These supplemental bills are issued separately from regular property tax bills and have their own due dates.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Clinton County require borrowers to maintain an escrow account for property taxes, especially when the loan-to-value ratio exceeds 80%. Your lender collects monthly property tax payments as part of your mortgage payment and holds these funds in a separate escrow account. The lender then pays your property taxes directly to Clinton County when due on February 14th and July 20th each year.

Lenders are required to conduct annual escrow analyses to ensure adequate funds are collected. If property taxes increase, your monthly escrow payment may be adjusted upward. If taxes decrease or the account has excess funds, you may receive a refund or see reduced monthly payments. You can request an escrow account disclosure from your lender at any time to verify the amounts being collected and paid. Property owners without mortgages or those who have paid off their loans are responsible for making tax payments directly to the Clinton County Treasurer by the established due dates.

Q: What tax credits are available and do I need to apply?
