Cascade County tax lien assignments, Montana

Verified

The treasurer's online presence is built around parcel lookup and payment: tax and parcel data is updated nightly, and property taxes can be paid securely online by credit card. The property tax page also advertises two payment plan options for owners, an Alternative 7-Payment Plan for real estate and a monthly plan for mobile homes that are behind, which is where the county puts its delinquency effort in public.

Selling office: Cascade County Treasurer's Office, 121 4th Street N, Number 1A, Great Falls, MT 59401; phone 406-454-6850

Next sale: Lien attachment: Monday, August 2, 2027, the first working day in August. The county posts no assignment opening date, so the working calendar is the state one: liens attach on the first working day in August and assignment questions go to the treasurer's office at 406-454-6850. The Notice of Pending Assignment cannot be mailed earlier than August 15.

Plan around the state calendar, since the county publishes no local one: attachment on the first working day in August, certified notices from August 15, and a three year redemption clock from attachment. A phone call to the treasurer's office is the first step, not a web form.

Research Cascade County parcels before you bid

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across Cascade County, searchable by address, owner, or county, including parcels that never reach a sale list.

How Montana tax lien assignments work

Taxes are due in halves, on November 30 and May 31. A delinquent installment draws a 2 percent penalty at once and interest at 5/6 of 1 percent per month until paid (MCA 15-16-102).
The county warns, then attaches. The notice of pending attachment is published by the last Monday in June and mailed to the assessed person at least two weeks before attachment; the treasurer attaches the lien no later than the first working day in August, and the county itself is the possessor of the lien (MCA 15-17-122 and 15-17-125).
A buyer takes the lien by assignment. The buyer mails the Notice of Pending Assignment by certified mail to the person the property was assessed to, not earlier than August 15, at least two weeks before payment and not more than 60 days before purchase, gives the treasurer proof of the mailing, and pays the full delinquency of taxes, penalties, interest, and costs. There is no bidding and no premium (MCA 15-17-323).
Competing buyers are sorted by county policy, not by price. Treasurers publish their own rules for competing requests, from preference lists and lotteries to a card draw, and an assignee may later reassign the lien to another buyer for any consideration (MCA 15-17-323).
Redemption runs three years from attachment. The owner, an occupant, the holder of an unrecorded interest, or another interested party may redeem by the first working day in August three years after attachment; a subdivided residential or commercial lot with delinquent special assessments and no habitable structure redeems in two years (MCA 15-18-111).
The final year notice is mandatory. Between May 1 and May 30 of the year the redemption period expires, the assignee must notify the occupant and every interested party that a tax deed may be issued, and file proof within 30 days; an assignee who fails to give the notice has the lien and the assignment certificate cancelled (MCA 15-18-212).
The deed issues, or the home is auctioned. For most property the treasurer grants the assignee a tax deed on payment of the deed fee and notice costs. Where the property is a dwelling occupied by its record owner, the treasurer instead holds a public auction whose opening bid adds half the assessed value of the land and dwelling, and that half value component and any overbid are paid to the former owner as surplus (MCA 15-18-211 and 15-18-219 to 15-18-221).

How buying works in Cascade County

The county publishes no additional local requirements beyond the state statute. Under MCA 15-17-323 the buyer mails the Notice of Pending Assignment by certified mail to the assessed person, at least 2 weeks before payment, not earlier than August 15 and not more than 60 days before purchase, shows the treasurer proof of that mailing, and pays the full delinquency. Start with a call to the office, which is the county's published route for assignment information.

There is no bidding on a lien An assignment is not won by offering more. The price is fixed by statute at the full delinquency, and where more than one buyer wants the same lien, the published policy of that county treasurer for competing requests decides who is served first.
What is due at assignment The full delinquency: taxes, penalties, interest, and costs from the date of delinquency, plus any assignment fee the county charges. Each county page carries the fee and payment forms that county publishes, or says plainly that the county does not publish them.
Reassignment An assignee may assign the lien on to another buyer for any consideration, by filing the statutory statement of reassignment with the treasurer (MCA 15-17-323).

Terms: what a bid actually costs

Deposit, Cascade County	Montana assignments have no bidder deposit. The full delinquency, meaning taxes, penalty, interest, and costs, is due at the moment of assignment. The county does not publish an assignment fee or the payment forms it accepts for assignments.
Payment, Cascade County	The county publishes online credit card payment for property taxes through its parcel system. It does not publish payment mechanics specific to assignment purchases, so confirm forms and timing with the treasurer's office before mailing any notices.
Redemption period	Three years from the date the county attaches the lien, ending on the first working day in August of the third year, with a two year period for a subdivided residential or commercial lot carrying delinquent special assessments and no habitable dwelling or commercial structure (MCA 15-18-111).
Interest the assignee earns	On redemption the treasurer pays the assignee back the amount paid for the assignment and any subsequent taxes the assignee paid into the lien, plus interest at 5/6 of 1 percent per month from the date of payment until redemption, the same rate the delinquency itself carries (MCA 15-16-102 and 15-18-114).
Penalty on delinquency	A delinquent installment draws a 2 percent penalty at once, then interest at 5/6 of 1 percent per month until paid. The penalty is part of what an assignment buyer pays at purchase and part of what redemption repays (MCA 15-16-102).
The final year notice, and the cancellation risk	Between May 1 and May 30 of the year the redemption period expires, the assignee must send the statutory notice that a tax deed may be issued, in the statutory form, and file proof of notice with the clerk and recorder within 30 days. An assignee who fails to give the notice has the lien and the assignment certificate cancelled (MCA 15-18-212).
The owner occupied auction	Where the property is a dwelling occupied by its legal titleholder of record, the tax deed goes through a public auction instead of a direct grant. The opening bid is the full redemption amount plus half the most recent assessed value of the land and the dwelling; the high bidder posts a deposit of 5 percent of the bid or $200, whichever is greater, and pays in full within 24 hours, and the half value component and any overbid go to the former owner as surplus (MCA 15-18-219 to 15-18-221).
Subsequent taxes	An assignee may pay later delinquent taxes on the same property into the assignment, and those payments are repaid with the same interest on redemption (MCA 15-18-112 and 15-18-114). Counties run a set window for these payments each summer, and each county page states the window that county publishes.

Liens nobody takes

A lien nobody takes stays with the county as possessor and remains assignable while the redemption period runs. The county publishes no tax deed sale schedule or leftover lien program on the pages read, and a deed to the county itself requires a commissioners' resolution under state law.

Before you bid

The notice is the first deadline of the deal An assignment bought without the certified Notice of Pending Assignment, mailed inside its window (not before August 15, at least two weeks before payment, and within 60 days of purchase), is not a valid assignment. Counties examine the proof of mailing closely, and receipts missing the address or the postmark are rejected.
Calendar the third year notice on day one The May notice in the year the redemption period expires is the step that kills assignments: miss it and the lien and the certificate are cancelled. The treasurer mails a reminder in January of that year, but the duty and the risk belong to the assignee.
Know which deed path the property is on A vacant parcel or a rental ends in a direct tax deed to the assignee; a home occupied by its owner ends in an auction where the assignee can be outbid and repaid instead. Price the assignment with both endings in view before paying the delinquency.
