There is no bidder registration, no deposit and no auction. Mail the person to whom the property was assessed a notice of pending assignment by certified mail, using the form printed in Mont. Code Ann. 15-17-323(6), carrying the owner of record, mailing address, legal description, parcel number and date of notice. Send it no earlier than August 15, at least two weeks before you pay, and no more than 60 days before the purchase. Then bring the certified mailing receipt and a copy of the notice to the Sheridan County Treasurer and pay the delinquent taxes, penalties, interest and costs plus the county's assignment fee. Confirm the fee, the accepted payment methods and any form the treasurer wants on file by calling (406) 765-3414 before the notice goes out.

Registration and deposit
Bidders at a Montana tax deed auction do not pre-register, but three requirements bind at the auction itself. An entity must give the treasurer written proof that it is a domestic entity before the treasurer will accept its opening bid, and a foreign entity may not buy at all. The high bidder posts a nonrefundable deposit at the time of sale of 5 percent of the bid or 200 dollars, whichever is greater, applied to the price on full payment, and the treasurer may ask bidders to show they can post it. Full payment of the purchase price plus the treasurer's auction costs is due within 24 hours of the sale, excluding weekends and legal holidays, and a bidder who misses it loses the parcel to the next highest bidder. Confirm the accepted payment methods with the county treasurer before the auction opens.

Check the state rules that change the bid
Read the Montana due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth. Which liens survive is state law, so read what survives a tax deed in Montana before you price the title work.Set a walk-away number
Work out what the parcel is actually worth with the rural land value estimator, then turn it into a ceiling with the tax deed max-bid calculator.
Over-the-counter (leftover) purchases
unsold liens and deeds
Every Montana tax lien is effectively over the counter, because assignment is the only way one is ever acquired. The county holds each lien from the day it attaches, and the treasurer must assign it to any person who mails the assessed owner the statutory notice and pays the delinquent taxes, penalties, interest and costs plus the county's assignment fee. After the late August allocation step, whatever is left sits with the treasurer and can be assigned on demand for the rest of the year, subject to the same notice rules: not earlier than August 15, mailed at least 2 weeks before payment and no more than 60 days before it. Older tax years are assignable the same way. Separately, land the county itself took by tax deed is sold at a public auction the county commissioners must order within 6 months of acquiring title, at a price the board fixes in advance, with the list of lands and the time and place published by the county clerk. That county land auction is not a tax lien or tax deed sale and the delinquent taxpayer may repurchase up to 24 hours before the first offering.

County notes
- There is no auction to attend in Sheridan County and no bidding method to learn. The tax lien attaches to the county on the first working day in August, and the only way a private investor takes it is an assignment from the county treasurer under Mont. Code Ann. 15-17-323, which is a certified-mail notice followed by a payment at the counter.
- About the parcel list. Sheridan County publishes no delinquent-parcel list online, and posts no assignment form, fee schedule or assignment policy on its website. The list an investor works from is the notice of pending attachment the treasurer publishes or posts by the last Monday in June, plus the file of every delinquent property kept in the treasurer's office and open to inspection under Mont. Code Ann. 15-17-122(2). Request it from the treasurer at (406) 765-3414 or [email protected].
- The treasurer's office is open Monday through Friday, 8 a.m. to 5 p.m., closed weekends and holidays, at 100 West Laurel Avenue in Plentywood. Megan Hansen is the county treasurer. The office's card payment service covers current real estate, mobile home and personal property tax bills only, so an assignment payment has to be arranged with the office directly.
- Montana's one tax deed auction is narrow, and Sheridan County publishes no notices of it. Ordinary property is deeded straight to the assignee once the redemption period runs out. Only a parcel containing a dwelling currently occupied by the legal titleholder of record goes to a public auction, which the treasurer must hold in the county within 60 days of the assignee's application and notice parcel by parcel, with a published minimum opening bid that carries half the most recent assessed value of the land and the dwelling, a nonrefundable deposit of 5 percent of the bid or 200 dollars, and full payment within 24 hours excluding weekends and legal holidays. Nothing about it appears on an annual calendar.
- A Montana sheriff's sale or foreclosure sale notice is a mortgage foreclosure and has nothing to do with the tax lien process. The August attachment is also advertised in some counties as a tax lien sale, but it transfers nothing to investors: it moves the lien to the county.
Montana rules
- Redemption
- The clock runs from attachment of the tax lien, which happens no later than the first working day in August, and it ends on the first working day in August of the third year after that. Redemption stays open for the whole period and the assignee cannot shorten it. On the residential auction track the right to redeem runs further still: the statutory notice tells the parties that a tax deed will be auctioned unless the lien is redeemed before the date of the auction, and 15-18-112(4) lets a particular tax year be redeemed until a deed has issued under 15-18-211 or 15-18-220. Interest and costs keep accruing until the day of redemption, and the county treasurer, not the assignee, calculates the payoff as of the date of payment. A redemption before the lien is assigned goes to the county; after assignment the treasurer pays the assignee.
- Deed deposit
- The high bidder posts a nonrefundable deposit with the county treasurer at the time of sale of 5 percent of the bid or 200 dollars, whichever is greater, and the deposit is applied to the sale price on full payment. Notice of the deposit requirement must be posted at the auction site, and the treasurer may require bidders to show they can post it. The treasurer may refuse to recognize a bid from someone who previously bid and then refused to honor the bid.
- Surplus proceeds
- Montana pays the owner's equity out rather than letting it be forfeited. The portion of the opening bid equal to half the most recent assessed value of the land and of the dwelling is treated as surplus funds, and so is anything a winning bid adds above the opening bid. Where the deed is bought by someone other than the assignee, the treasurer first repays the assignee the amount paid for the assignment, including delinquent taxes, penalties, interest and costs, plus everything paid on the tax deed application under 15-18-219(2). The treasurer then distributes the surplus to the legal titleholder of record within 30 days of receiving payment from the purchaser, whether or not the titleholder lives in Montana. On the ordinary non-auction track there is no sale, no bidding and no surplus: the assignee receives the deed itself.
A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
