How Tax Delinquent Property Sales Work in Montana
Montana does not hold a competitive lien auction. Each year the county attaches a tax lien to delinquent property in the county's own name — the lien attaches on the first business day of August — and the county becomes the statutory holder of that lien. An investor acquires the lien by taking an "assignment" from the county: paying all delinquent taxes, penalties, interest, and costs, and serving the required notice on the owner. The assignment is a redeemable lien, not title. It ripens into a tax deed only if the owner fails to redeem within the roughly 3-year statutory period and the assignee completes the notice and deed-application steps. For residential property, a Notice of Pending Tax Deed is required before the deed can issue. Assignments are available on a rolling basis rather than at a single sale date.
Bidding & Auctions
There is no bidding, bid-down, or premium in Montana — the county is the statutory purchaser of the lien, and an investor simply takes an assignment of it. To do so you pay the full delinquent amount and must strictly follow the certified-mail notice timing: notice to the owner is mailed at least two weeks before the purchase, not earlier than August 15, and not more than 60 days before. Because there is no auction, competing requests for the same lien are handled administratively by the county treasurer. Counties such as Yellowstone and Gallatin process assignments directly through the treasurer's office; there is no dominant online platform.
Redemption & Penalties
The owner keeps ownership and the right to redeem until the roughly 3-year period — measured from the date the county's lien attaches — expires. On redemption the owner pays the delinquent taxes plus a 2% penalty and interest at the statutory delinquency rate of 5/6 of 1% per month (about 10% per year), calculated daily, plus costs and any subsequent taxes the assignee paid. Because the exact expiration is parcel-specific, confirm it with the county treasurer. If the owner does not redeem and the assignee completes the required notices — including the residential Notice of Pending Tax Deed — the assignee can apply for a tax deed.
See Montana Code Annotated, Title 15, Chapters 17 and 18. Specific procedures vary by county — always verify with the local tax assessor/collector before bidding.

How do I buy a tax lien in Montana?▾
You don't bid at an auction. The county holds the lien, and you take an assignment of it by paying all delinquent taxes, penalties, interest, and costs and serving statutory notice on the owner. The lien attaches on the first business day of August, and assignments are taken thereafter.
What return does a Montana assignment earn?▾
On redemption the owner pays a 2% penalty plus interest at 5/6 of 1% per month — about 10% per year — calculated daily on the delinquent taxes and costs, plus any subsequent taxes you paid.
How long until I can get a tax deed in Montana?▾
About 3 years from the date the county's lien attaches. The exact expiration is parcel-specific, so verify it with the county treasurer, and note that residential property requires a Notice of Pending Tax Deed first.
Why is notice so important in Montana?▾
The assignment ripens into a deed only if you strictly follow the certified-mail notice timing. A defective notice can void the deed, so the notice steps are the heart of a Montana deal.
