How Tax Sales Operate in Montana
Under Mont. Code Ann. § 15-17-121, delinquent property taxes follow a precise statutory timeline. Understanding the difference between bidding on Tax Lien Assignment and purchasing over-the-counter is essential for investors.
Bidding & Auction Process
Auctions are conducted online via In-Person County Treasurer Office 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 (Tax Lien Assignment (OTC Direct Purchase))
In Montana, unsold properties or tax lien certificates become available as Tax Lien Assignment (OTC Direct Purchase). Buyers can purchase these parcels directly over-the-counter without attending an open outcry auction.
