How Property Tax Works

Clinton County, Indiana operates on a property tax system that funds essential local services including schools, fire protection, emergency services, and county operations. For the 2025 tax year (collected in 2026), the certified property tax rate is 2.3000%, though this represents the county-wide average. Property taxes in Clinton County are calculated based on assessed value, which is determined by the County Assessor's Office and typically reflects a percentage of fair market value.

Actual tax rates vary significantly by location within Clinton County due to special taxing districts, including school districts, library districts, fire districts, and municipal boundaries. Property owners may pay different effective rates depending on which combination of these districts serve their property. The county uses a complex levy system where multiple governmental units contribute to the total tax rate, making it essential for property owners to understand their specific district assignments when calculating their expected tax liability.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Clinton County are additional property tax assessments that occur when there are changes to property ownership, new construction, or improvements completed after the annual assessment date. These taxes are calculated on a pro-rated basis from the date of the triggering event through the end of the current tax year. Common triggers include the completion of new construction, major renovations that increase assessed value, or changes in property use classification.

For example, if a property owner completes a $100,000 home addition in September, and their district tax rate is 2.3%, they would owe approximately $767 in supplemental taxes (($100,000 × 2.3%) × 4 months remaining ÷ 12 months). Supplemental tax bills are typically issued within 60-90 days of the assessment change and have separate due dates from regular property tax installments.

Escrow & Property Taxes

Most mortgage lenders in Clinton County require property tax escrow accounts for properties with loans exceeding 80% loan-to-value ratio. Lenders collect monthly escrow payments equal to 1/12th of the annual property tax bill, plus a cushion amount typically not exceeding two months of payments. Property taxes in Clinton County are collected in two semi-annual installments, and lenders coordinate payments with the Clinton County Treasurer to ensure timely payment by the May 10th and November 10th deadlines.

Property owners should verify their escrow account balances annually when tax bills are issued, as assessment changes, rate adjustments, or special assessments can create shortages or surpluses. Indiana law requires lenders to provide annual escrow analysis statements and adjust monthly payments accordingly. Property owners can contact their lender's escrow department to request current balance information and review payment history for accuracy.
