Montana Tax Lien & Tax Deed Auctions

Every Montana county we track, with its next sale date, platform, and rules — each field sourced directly from the county or state's official page and re-verified on a rolling basis.

Montana law (Mont. Code Ann. Title 15, Ch. 16/17/18): Not a competitive auction: the county becomes the tax lienholder, and an investor takes a lien by ASSIGNMENT (pay the delinquency + notify the owner). 10%/yr plus a 2% penalty; ~3-year redemption.
