Montana Tax Sale Questions
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.
