Yellowstone County auction guide

Reviewed Nov 8, 2026 · Based on official county sources

Yellowstone County has separate tax lien assignment and tax deed auction processes. Its Treasurer warns that legislation has changed the procedures and directs buyers to current Montana statutes and legal counsel.

Tax lien assignments

The county attaches liens on the first working day of August and posts delinquent parcels. Assignment buyers must send a certified-mail notice of pending assignment by the stated August postmark deadline and complete the statutory steps described on the page.

Tax deed auctions

The Treasurer posts the date, time and place for each tax deed auction. The reviewed notice describes an auction in the Treasurer's conference room, but its date has passed. No upcoming date is confirmed here.

Legal preparation

Use the current Montana statutes linked by the county. The Treasurer calls its page an overview and makes buyers responsible for studying the law and retaining counsel.

Official references

Schedules and procedures can change. This guide summarizes the cited sources; the county’s current auction notice controls the requirements for a particular sale.
