Tax Reports and Delinquent Taxes
Delinquent Taxes
The County Clerk's Office is responsible for collecting delinquent/past due taxes for sold properties. Due to state statute, the only forms of payment acceptable are cash, cashier's check, or money order. All checks need to be made payable to the Boone County Clerk. For questions or to find out how much is owed on a delinquent property, call 815-544-3103. Please have your parcel number (PIN) ready when calling.
Tax Reports
Every year the County Clerk calculates the rates for the various taxing districts in Boone County. These rates are calculated using the levies filed by the taxing district and the equalized assessed value of the property within that district as well as other factors.
