How Tax Sales Operate in Wisconsin
Under Wis. Stat. § 75.01 et seq., delinquent property taxes follow a precise statutory timeline. Understanding the difference between bidding on Automatic Tax Certificate / Foreclosure and purchasing over-the-counter is essential for investors.
Bidding & Auction Process
Auctions are conducted online via Wisconsin Surplus Online Auction or in person by the County Treasurer. Winning bidders are required to tender payment via wire transfer, certified check, or ACH within statutory deadlines.
Over-The-Counter Lands (County Real Estate Direct Inventory (OTC))
In Wisconsin, unsold properties or tax lien certificates become available as County Real Estate Direct Inventory (OTC). Buyers can purchase these parcels directly over-the-counter without attending an open outcry auction.
