How to claim unclaimed money in Montana
The Montana Department of Revenue is estimated to hold more than $200 million in unclaimed money — old bank accounts, uncashed checks, and insurance payouts, all sitting with the state until someone comes looking. In a state built on mining and ranching, a lot of that money is mineral royalties and natural resource payments. Here’s exactly how to find out if any of it belongs to you — and how to get it back for free.
Unclaimed property ends up with the state when a bank, employer, insurer, or utility loses touch with the rightful owner. Under Montana law (Title 70, Chapter 9), most property types — including bank accounts, uncashed checks, and insurance proceeds — are presumed abandoned after five years of no owner activity. Once that dormancy period passes, the holder must report and remit the property to the Montana Department of Revenue’s Unclaimed Property Program. From there, the state holds it indefinitely under your name, waiting for you to claim it.

You don’t need to still live in Montana for the state to be holding something in your name. Most claims trace back to something ordinary:
- Closed a bank account and left a small balance behind
- Never cashed a payroll check, insurance payout, or matured CD
- Moved and forgot to alert a bank or stockbroker of a new address
- Inherited from a relative who held an account or safe deposit box in Montana
- Owned stock, dividends, or mineral royalty payments tied to a Montana company or lease
- Left a utility deposit or refund unclaimed after moving
Step-by-step: claiming your money in Montana
-
Search every name you’ve used
Try your current legal name, maiden name, nicknames, and past spellings on the official Montana Unclaimed Property Portal. Property is often filed exactly as it was reported years ago.
-
Confirm the listing is yours
Match the last known address, employer, bank, or company name in the record to somewhere you’ve actually lived, worked, or banked before you move on to filing.
-
File the claim online
Submit your claim through Montana’s TransAction Portal (TAP) with proof of address and documentation connecting you to the property. Heirs will also need proof of the original owner’s death and their own legal right to the property.
-
Wait for review and payment
Simple, well-documented claims are typically processed within 60 to 90 days. Claims involving estates or large amounts can take longer while ownership is verified, and refunds are issued as a paper check from the Department of Revenue.
Unclaimed property is filed under your address at the time — not where you live now. If you’ve ever moved to or from Montana, worked elsewhere, or banked in another state, that state may owe you too.
