November 5 at 4:30pm: this is the LAST day to pay your delinquent taxes before they go to tax sale. Payments must be in the form of a Cashier's Check or money order.

What happens if your taxes get sold? They are now back taxes and can only be redeemed at the Clerk and Recorders office. There will be additional costs and interest added; it is important to call for pay off amounts and methods of payment. Back taxes can be redeemed at anytime following the tax sale.

Hello tax payers, when writing your check out for taxes, please make it payable to Carroll County Treasurer. My bank will not accept any other way it is written. This then causes delays of getting your taxes deposited.

Again checks payable to Carroll County Treasurer only, please.

Thank you.
