How Flathead County sells delinquent taxes

Tax certificate sale (lien)

In person at the county treasurer's counter, or by mail or email where the county allows it. Montana holds no tax lien auction, so there is no online bidding platform, no registration portal and no vendor to sign up with.

Registration
There is no bidder registration and no bidding.
Sale list
Delinquent Real Estate Property Tax List
When it runs
Notice of the pending tax lien is published in late June, and the county states the lien is attached to delinquent properties in early August, no later than the first working day in August. Assignments can begin once the county is listed as purchaser and the list of eligible properties is made available. A Notice of Pending Assignment cannot be postmarked earlier than August 15 and must be postmarked at least two weeks before payment. The Treasurer's Office does not conduct tax sale assignment business during the tax season months of May and November.
Registration and deposit

There is no bidder registration and no bidding. An investor acquires a lien by requesting an assignment from the Treasurer's Office. First mail a Notice of Pending Assignment to the person the property was assessed to, postmarked at least two weeks before payment and not earlier than August 15. Then present the exact delinquency payment amount, the $50 assignment fee per assessor number, a priority list in Excel format, copies of the notices sent, certified mailing receipts showing both the postmark date and the address used, and a W-9 for interest earned. Reassignments and junior liens require separate payment. A certified receipt that does not show both an address and a postmark is not accepted; investors sending large volumes of certified mail may use the USPS manifest mailing system if they supply a copy of the official manifest.

Sale format and venue
Montana runs no competitive tax lien auction. The tax lien attaches to Flathead County itself, and a private investor takes it only by assignment from the County Treasurer under Mont. Code Ann. 15-17-323. Where more than one party seeks the same assignment, Flathead County sets the order by a card draw: a card is chosen on behalf of each party, order runs from the highest card to the lowest with aces treated as low, and the party holding the highest card gets first selection. The assignment fee has been $50 per assessor number since January 1, 2024. Certificates are not issued on the day of payment. The Treasurer reviews every submission for sufficiency first and the sale is not final until that review is complete; once approved, the Tax Lien Sale Certificate is filed with the Clerk and Recorder and the original is delivered to the purchaser. Delinquent balances carry interest of 5/6 of 1% per month plus a one-time 2% penalty.

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.
Run by
County Treasurer
Frequency
As applied for. There is no deed sale calendar, and most parcels never reach an auction at all.
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.

Flathead County tax sale list and auction calendar

For Flathead 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

    Use Delinquent Real Estate Property Tax List for the current advertised parcels, then recheck it before the auction.

  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 Flathead County

  1. Start with the live sale list

    Pull the current advertised parcels from Delinquent Real Estate Property Tax List. Lists can change before the sale, so recheck the county source before you price a parcel.

  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

  • Flathead County publishes two delinquent tax lists as downloadable reports on the Treasurer's delinquent property tax page: a Delinquent Real Estate Property Tax List and a Delinquent Personal Property Tax List. Both are generated from the live tax roll, so their contents change as payments come in. There is no separate auction catalog because the county holds no auction.
  • The list of parcels eligible for assignment is released by the Treasurer's Office once the county is listed as purchaser of the lien. Notice of the pending attachment of a tax lien must also be first published in the newspaper on or before the last Monday of June.
  • The Treasurer also posts an Unpaid Tax Roll data file, a fixed-width download aimed at banks, mortgage servicers and batch payment services. Character 65 of each record flags whether an assignment already exists on that assessor number, which is useful for screening before requesting one.
  • A tax lien may be redeemed by the owner, the holder of an unrecorded or improperly recorded interest, the occupant, or any interested party, through the first working day in August three years after the lien attached.
  • For a third-party purchaser, recoverable cost includes certified mailing postage, title search expenses where needed, required publication costs, and the filing cost for proof of notice.
  • Flathead County does not mail a second statement for the May 31 installment, and payoff figures move daily, so confirm the exact amount with the Treasurer's Office before tendering payment for an assignment.

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.
