How Property Tax Works

Harrison County, Indiana operates on a property tax system that funds essential local services including schools, county government operations, townships, and various special districts. Property taxes are the primary revenue source for the South Harrison School Corporation and other local governmental entities within the county. The property tax system in Harrison County is administered by the County Assessor's office and collected by the County Treasurer.

Property tax rates in Harrison County vary significantly by location within the county due to different combinations of taxing units and special districts. For the 2025 tax year, the base Harrison County rate is 0.0033650 (approximately 0.34%), but when combined with school districts, townships, and other local taxing units, the total effective rate can reach over 3% of assessed value. Actual tax bills depend on your specific location within the county, as different townships and school districts have varying rates and levies.

Section 4

Supplemental Tax Bills

Supplemental taxes in Harrison County are additional property tax assessments issued when there are changes to property ownership, new construction, or property improvements that occur after the regular assessment date but before the end of the tax year. These supplemental bills cover the period from when the change became effective through the remainder of the current tax year.

Common triggers for supplemental taxes include: purchase of property that wasn't properly assessed, completion of new construction or major renovations, change in property use (such as converting agricultural land to residential), or correction of assessment errors. The supplemental tax is calculated by applying the current year's tax rate to the difference between the old and new assessed values, prorated for the portion of the tax year remaining.

For example, if you complete a $50,000 home addition in March that increases your assessed value by $45,000, and your total tax rate is 3.2%, you would owe approximately $1,440 in supplemental taxes ($45,000 × 0.032) prorated for the remaining 9+ months of the tax year, resulting in a supplemental bill of roughly $1,080.

Escrow & Property Taxes

Most mortgage lenders in Harrison County require property tax escrow accounts for borrowers with less than 20% down payment. Your lender collects monthly escrow payments along with your mortgage payment, typically 1/12 of your annual property tax bill plus a cushion amount. The lender pays your property taxes directly to the Harrison County Treasurer when bills are due.

Property tax bills in Harrison County are mailed on December 1st each year and are due in two installments: the first installment by January 31st (without interest) and the second installment by July 31st. Your mortgage servicer should receive and pay these bills automatically from your escrow account. However, it's important to verify that payments are made on time, as you remain ultimately responsible for tax payments even when using escrow.

You can monitor your property tax account online through the Harrison County Treasurer's website and verify that escrow payments have been properly applied. If you pay off your mortgage or refinance, ensure there's no gap in tax payment responsibility, and contact your lender about escrow account closure and any remaining balance refunds.
