How Property Tax Works

Carroll County, Indiana operates on a property tax system that serves as the primary funding mechanism for local government services, schools, libraries, and various special districts. Property owners in Carroll County pay taxes based on their property's assessed value multiplied by the local tax rate, which varies significantly by location within the county due to different combinations of taxing districts including townships, school corporations, libraries, and other special service areas.

The property tax rate for Carroll County in 2025 is proposed at 1.038%, representing a two-cent increase from the 2024 rate of 1.018%. However, actual tax rates vary considerably throughout the county depending on which special taxing districts serve your specific property location. These districts can include different school corporations, library districts, fire departments, and other local service providers, making it essential to understand your property's specific tax district assignment to determine your exact tax burden.

Property taxes in Carroll County fund essential services including public education through local school corporations, emergency services, road maintenance, parks and recreation, library services, and general county operations. The assessment and collection process follows Indiana state guidelines, with assessments based on market value and various tax credits available to qualifying property owners who submit the required applications.

Supplemental Tax Bills

Supplemental property taxes in Carroll County are additional tax assessments that occur when there are changes to a property's assessed value outside of the regular annual assessment cycle. These supplemental assessments most commonly occur due to new construction, property improvements, ownership changes that trigger reassessment, or corrections to previous assessments that resulted in undervaluation.

When a supplemental assessment is issued, it covers the period from when the change occurred (such as completion of construction or the date of sale) through the end of the current tax year. The supplemental tax is calculated by applying the current tax rate to the difference between the new assessed value and the previous assessed value, then prorating it for the applicable time period.

For example, if you complete a $50,000 home addition in Carroll County in July, and your property is in a district with a 1.10% tax rate, the supplemental assessment would be calculated as follows: $50,000 (additional assessed value) × 1.10% = $550 annual tax increase, prorated for 6 months (July-December) = $275 supplemental tax bill. This supplemental bill would be issued separately from your regular property tax statement and typically has its own payment due date.

Escrow & Property Taxes

Most mortgage lenders in Carroll County require property tax escrow accounts for borrowers who put down less than 20% or request escrow services. Your lender collects monthly property tax payments as part of your mortgage payment, typically calculating 1/12 of your annual property tax bill plus a small cushion to account for potential tax increases.

Property tax statements in Carroll County are mailed by April 15th each year, with payment due dates of May 10th for the spring installment and November 10th for the fall installment. If you have an escrow account, your lender receives these statements and makes payments on your behalf. However, it's important to review your annual escrow analysis statement to ensure adequate funds are being collected, especially given Carroll County's recent tax rate increases.

Lenders are required to provide an annual escrow analysis showing the previous year's activity and any adjustments needed for the coming year. If your property taxes increase due to reassessment or rate changes, your lender may require an escrow shortage payment or increase your monthly payment to cover the higher taxes. You can verify that your lender is making timely payments by checking with the Carroll County Treasurer's office or monitoring your property's tax status online through the county's payment portal.
