How to Search Montana Property Records (Start Here)
Property records in Montana are maintained at the county level. The Department of Revenue (state-level assessment) handles property valuations and assessment data. The County Treasurer handles tax bills and payments. These are separate offices with separate databases.
What this page covers: Montana property assessment lookups, tax record searches, and parcel/ownership data. What it does not cover: Recorded documents like deeds and mortgages (those are on the Recorded Documents page) or property transfer history.
Where to start: For property values and tax assessments, start with the Department of Revenue (state-level assessment). For tax payment history and bills, go to the County Treasurer. For ownership verification, you may need both the assessment records and the recorded documents.
Common mistake: Property assessment records (values and taxes) and recorded documents (deeds and liens) are maintained by different offices in Montana. The Department of Revenue (state-level assessment) handles assessments; the Clerk and Recorder handles recordings. Search both if you need the full picture.

Five Things People Get Wrong About Montana Property Records
MYTH"Zillow shows the official Montana value."
FACTNo. A Zestimate is an algorithm's guess. The official value is set by the county assessor, and that's the number property taxes are built on.
MYTH"The assessor and the recorder are the same office."
FACTTwo different jobs: the recorder files deeds and mortgages; the assessor sets taxable values. Which office you need depends on which question you're asking.
MYTH"There's a national property database."
FACTThere isn't. No federal registry of who owns what exists, Montana property records are kept county by county, office by office.
MYTH"The deed shows the current mortgage balance."
FACTThe recorded mortgage shows what was borrowed on day one. Payoff balances are private between lender and borrower, no county office has them.
MYTH"Assessed value equals market value."
FACTDifferent numbers for different jobs. Assessed value exists for taxation and in most places sits below what the house would sell for.

What's the difference between the Assessor and the Recorder in Montana?▼
The county Assessor determines property values for tax purposes and maintains the parcel roll.

The Official Montana Property Records at mtrevenue.gov publishes the full list.

Parcel identification numbers (APN, PIN, or parcel number depending on the county) are assigned by the county assessor. They appear on every tax bill and on the county's online property-search interface. Once you have the parcel ID you can look up assessed value, ownership history, and recorded documents through the county site; the statewide overview is at mtrevenue.gov.
How do I challenge a Montana property assessment?▼
Assessment appeals in Montana are filed at the county level with the local assessment appeals board, typically within a deadline set after annual valuation notices are mailed. The Official Montana Property Records publishes the statewide rules, deadlines, and appeal forms at mtrevenue.gov.
