The purpose of the tax sale is to collect unpaid taxes. The Annual Tax Sale takes place in June of each year.

Delinquent taxes on a parcel subject to sale will be advertised in June in the Boone News Republican, Ogden Reporter, and Madrid Register. Properties are listed in parcel number order and have a sequence number for bidding purposes. Copies of the list are available at the Boone County Treasurer's Office. In addition, a print-out of those parcels may also be purchased.

The investor is responsible for all research on parcels available for auction.
