How Property Tax Works

Franklin County, Indiana operates on a property tax system that funds essential local services including schools, county government operations, public safety, and infrastructure maintenance. Property taxes in Franklin County are based on assessed values and millage rates that vary by location within the county due to different special taxing districts such as school corporations, townships, and municipal boundaries.

For the 2025 tax year, Franklin County has tentatively set a millage rate of 6.36 mills, which represents an increase from the previous year. The effective tax rate for property owners typically ranges from approximately 0.6% to 1.2% of assessed value, depending on the specific taxing districts that apply to each property location. Property owners should note that their actual tax rate depends on which school district, township, and municipality their property is located within, as each of these entities may levy additional taxes beyond the base county rate.

When Are Property Taxes Due?

First Installment
May 10
Delinquent after Dec 10
Second Installment
Nov 10
Delinquent after Apr 10
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 are special real estate tax bills issued when there are new changes or improvements to a property that have not been previously assessed. This typically occurs when new construction is completed, significant renovations are made, or when ownership changes trigger a reassessment that results in a higher assessed value mid-year.

The supplemental tax is calculated by applying the current tax rate to the increase in assessed value, prorated for the remaining months in the tax year. For example, if a property owner completes a $50,000 home addition in August and the total tax rate is 1.0%, the supplemental tax would be approximately $500 × (5 months remaining ÷ 12 months) = $208 for the remainder of that tax year. Supplemental tax bills are issued separately from regular property tax bills and have their own due dates.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Franklin County require borrowers to maintain an escrow account for property taxes, which means your monthly mortgage payment includes a portion that goes toward property taxes. Lenders typically collect 1/12th of your annual property tax bill each month and pay the taxes directly to Franklin County on your behalf when they become due.

Property taxes in Franklin County are due in two installments: May 12, 2025, and November 10, 2025, for the 2025 tax year. Lenders usually pay these installments on time to avoid penalties. Property owners should verify that their lender has made timely payments and should review their annual escrow analysis to ensure adequate funds are being collected. If you pay your own taxes (no escrow), you're responsible for making payments by the due dates to avoid delinquency charges that begin accruing after May 12 for the first installment.
