How Prairie County sells delinquent taxes

Tax certificate sale (lien)

In person
Run by
Prairie County Treasurer
Frequency
annual
Registration
There is no bidder registration, no deposit and no auction to sign up for.
When it runs
Montana runs one statutory calendar and Prairie County follows it, so there is no sale day to circle. The treasurer publishes or posts the notice of pending attachment on or before the last Monday in June, then attaches the tax lien to the county no later than the first working day in August. An investor's notice of pending assignment may not be mailed before August 15, and it must go out at least 2 weeks before payment and no more than 60 days before the purchase, so the earliest a Prairie County lien can change hands is about August 29. Liens the county still holds after that stay assignable at the treasurer's counter the rest of the year. The delinquency that starts the clock runs off the due dates the treasurer's office prints: real estate on November 30 and May 31, mobile homes on May 31 and November 30, and personal property "Payment due June 30, or 30 days after mailing of tax notice."
Registration and deposit

There is no bidder registration, no deposit and no auction to sign up for. Mail the person to whom the property was assessed a notice of pending assignment by certified mail, in the form printed at Mont. Code Ann. 15-17-323(6), showing the owner of record, mailing address, legal description, parcel number and date of notice. Send it no earlier than August 15, at least 2 weeks before you pay and no more than 60 days before the purchase. Then bring proof of that mailing to the Prairie County Treasurer at 217 Park St W in Terry and pay the delinquent taxes, penalties, interest and costs. The office lists checks, cash, money orders, VISA, Mastercard and e-checks among the payment methods it takes. Prairie County publishes no assignment fee, no assignment-day schedule and no written policy for competing requests, so call the treasurer at 406-635-5577 before you mail anything and confirm the fee, the form and how the office decides between two investors who want the same parcel.

Sale format and venue
Montana has no competitive tax lien sale and Prairie County holds none. Under Mont. Code Ann. 15-17-125 the treasurer attaches the lien no later than the first working day in August and the county becomes its possessor. Mont. Code Ann. 15-17-323 then obliges the treasurer to assign that lien to any person who mails the assessed owner the statutory notice and pays the delinquent taxes, penalties, interest and costs. Nothing is bid up or bid down, the price is the delinquency itself, and the treasurer's office sums up its own part in one line, that it "Processes tax lien sales & redemptions." On the parcel list: Prairie County posts no tax lien list and no delinquent-parcel list, and its tax portal looks up one property at a time by parcel number, owner name, address, geocode or section, township and range. Under Mont. Code Ann. 15-17-122 the list of every property with delinquent taxes is kept on file in the county treasurer's office and open to inspection, and the notice of pending attachment runs in the county's legal newspaper by the last Monday in June. Those two are the list in Prairie County, so ask the treasurer's office for the current one rather than hunting for a download. In person at the Prairie County Treasurer's counter in the courthouse at 217 Park St W in Terry. Montana holds no tax lien auction, so there is no online bidding platform and nothing to register for.

Tax deed sale

In person at the county treasurer's office during regular office hours. Mont. Code Ann. 15-18-220(6) permits a county to conduct the auction electronically but does not require it, and there is no statewide platform.

Typical timing
Nothing is scheduled in advance.
When it runs
Nothing is scheduled in advance. Once the redemption period runs out, 3 years after attachment or 2 years for an unimproved subdivided lot with delinquent improvement district assessments, the path forks on what is standing on the parcel. Ordinary property is deeded straight to the assignee under Mont. Code Ann. 15-18-211 for a 25 dollar deed fee plus the county's notice costs, with no auction and no bidders. Property with a dwelling currently occupied by the legal titleholder of record goes to a public auction instead: the assignee files a tax deed application with the treasurer after the redemption period expires, and the treasurer must hold the auction in the county within 60 days of receiving it. The treasurer publishes the auction notice with the date, time, location, legal description, deposit requirement and minimum opening bid. The auction runs during the treasurer's regular office hours and may be conducted electronically.
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.

Sale format and venue
The opening bid is the amount needed to redeem the lien, plus everything the assignee paid on application, plus the tax deed and recording fees, plus an amount equal to half the most recent assessed value of the land and of the dwelling. An independent appraisal meeting Montana Board of Real Estate Appraisers standards and conducted within 6 months may stand in for the assessed value. The treasurer may not take a bid below that figure. The half-value component, and anything bid above the opening bid, is surplus: the treasurer repays the assignee first where someone else buys, then pays the surplus to the legal titleholder of record within 30 days. If nobody bids, or no bidder pays, or the assignee wins and fails to pay inside the 24 hours, the treasurer cancels the assignment and files a notice of cancellation, and the investor loses the lien position entirely. The owner may redeem right up to the day of the auction.

Prairie County tax sale list and auction calendar

For Prairie County tax sale 2026 searches, use the county-run sources below rather than a copied parcel list, and confirm the parcel, registration cutoff, deposit, and payment deadline against the county before you bid. If the parcels on this list are vacant land rather than houses, what buying land at a tax sale hands you is the place to start.

  1. Get the advertised list

    A county sale-list URL is still being verified. Use the office and platform details on this page before relying on a copied list.
  2. Register to bid

    Ask the county office how and when to register; many counties close registration days or weeks before the sale.
  3. Sale day

    Nothing is scheduled in advance. The sale is live and in person; there is no online bidding platform. Confirm the venue and hour with the county office before you go.
  4. Confirm with the office

    If the list, platform, and notice disagree, use County Treasurer as the source to confirm which parcels are actually offered.

Before you bid in Prairie County

  1. Start with the live sale list

    The county sale-list URL is still being verified. Use the county office contacts below and confirm the advertised parcels directly before you price a bid.
  2. Confirm 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.

  3. 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.
  4. 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

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 and no bidding method to learn here. The lien attaches to Prairie County itself on the first working day in August, and a private investor takes it only by assignment from the Prairie County Treasurer under Mont. Code Ann. 15-17-323.
  • Prairie County publishes no delinquent-parcel list and no tax lien list on its website, and the county tax portal searches one parcel at a time rather than returning a list. The list required by Mont. Code Ann. 15-17-122 sits on file at the treasurer's office and is open to inspection, and the June notice of pending attachment appears in the county's legal newspaper. Call the treasurer at 406-635-5577 to ask for the current one.
  • The assignment fee, the paperwork the office wants and the policy for two investors seeking the same parcel are all county policy under Mont. Code Ann. 15-17-323(1)(b), and Prairie County publishes none of the three. Montana counties set their own assignment fee per parcel, so budget for one and confirm the amount with the treasurer before mailing a notice.
  • Prairie County publishes no tax deed auction notices. A Montana tax deed auction happens only in the narrow case described at Mont. Code Ann. 15-18-219, where the parcel contains a dwelling currently occupied by the legal titleholder of record, and it is scheduled parcel by parcel after the assignee applies rather than on an annual calendar. Ordinary parcels are deeded straight to the assignee with no auction and no bidders.
  • The deadline that ends a Montana position is a notice, not a payment. In the year the redemption period expires the treasurer notifies the assignee of that obligation in January, and the assignee must give the notice that a tax deed may issue between May 1 and May 30 and file proof of it with the county clerk and recorder. Miss the proof and the treasurer cancels both the tax lien certificate and the assignment certificate, and the position is gone.
  • A Prairie County sheriff's sale or foreclosure sale is a mortgage foreclosure and has nothing to do with the tax lien process. Do not treat one as a tax sale.

Montana rules

Max interest rate
10% per year, fixed by statute (nothing is bid)
Minimum return
No statutory floor; every certificate earns the same statutory rate
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.
Governing statute
Mont. Code Ann. Title 15, ch. 17

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.
