Montana Unclaimed Property: How to Search & Claim Your Money (2026)

Montana's Department of Revenue has returned more than $111 million in unclaimed property to residents to date. Unlike most states, Montana now proactively matches and pays out some small claims automatically, without the owner ever filing anything. Here is how Montana's unclaimed property program works, including that automatic-payment program, and how to search for and claim what the state might be holding for you.

How Montana's Unclaimed Property Program Works

Montana's unclaimed property program is run by the Department of Revenue, not the State Treasurer's office as in many other states. When a bank, employer, insurer, or other business owes you money and cannot reach you for long enough, it must attempt to locate you and then report and turn the property over to the Department of Revenue rather than keep it. This transfer is called escheatment, and Montana's version is custodial: the Department of Revenue holds the property on your behalf, and you or your heirs can generally file a claim to get it back.

How to Search for Your Montana Unclaimed Property

Montana's official search and claim tool is the TransAction Portal, known as TAP, reachable at tap.dor.mt.gov and linked from the Department of Revenue's own unclaimed property page. The state's older branded address, mycash.mt.gov, now redirects to the same official portal. Montana's records are also searchable through the free multi-state tool MissingMoney.com, though the state's own TAP portal remains the authoritative source. Search under every name you have used, and check any other state where you have lived, worked, or banked, since property follows the address you had at the time it was reported.

How to File a Claim

Filing a claim through TAP is free, and the Department of Revenue is direct about it: "You do not need to pay a third-party to claim your property." Mont. Code Ann. 70-9-815 gives the department up to 90 days after a claim is filed to allow or deny it and to send written notice of the decision, and if the claim is allowed, up to 30 more days to deliver or pay the property. The department's own claims page frames the same window as having 90 days to complete your claim once all documentation is received from you, and claims are handled in the order they arrive. If the department requests additional documentation and you do not provide it within six months, the claim is denied, though you can reopen it or file again later. If you move while a claim is pending, provide proof of your new address, such as a lease, mortgage statement, or utility bill.

Montana's Dormancy Period, Explained

Montana generally sets its dormancy period, how long a business can hold your money before it must report and remit it to the state, at five years for checking accounts, savings accounts, and accounts payable. Uncashed payroll and wages have a shorter dormancy period of just one year, and gift certificates become reportable three years after December 31 of the year they were sold. Once the applicable period passes, the holder must turn the property over to the Department of Revenue.

House Bill 88: Montana Now Pays Some Small Claims Automatically

Montana stands out among states for a 2025 law, House Bill 88, that lets the Department of Revenue skip the claim-filing step entirely for smaller amounts. Under the law, the department can pay or deliver property directly to a person without requiring a claim if three things are true: the person is the apparent owner named on the original unclaimed property report, the department has reasonably validated that person's identity and address using state records such as tax filings, and the property is worth $1,000 or less.

In practice, this means the Department of Revenue can cross-reference its unclaimed property reports against Montana tax records, confirm a match, and simply mail a check, no search or claim form required on your part. If you receive a check from the Department of Revenue referencing unclaimed property, it is very likely this program at work rather than something you need to apply for after the fact. Montana is part of a small but growing group of states experimenting with this kind of proactive small-claim payment, though the $1,000 threshold and the tax-record matching method are specific to Montana's version of the idea.

Tip: Because the automatic-payment program under HB 88 relies on validating your identity and address against state records, keeping your address current with the Montana Department of Revenue, such as when you file your state tax return, improves the odds that a small unclaimed balance in your name gets matched and mailed to you without you having to do anything.

Avoiding Unclaimed Money Scams

The Department of Revenue is explicit that you never need to pay anyone to claim your own property through TAP. Be cautious of two different things. Paid "finder" or "asset recovery" services simply charge a fee to do the searching and filing for you. They are unnecessary in Montana, since the state's own process, including its automatic small-claim payments, already costs nothing.

Montana also regulates those agreements by statute. Under Mont. Code Ann. 70-9-825, an agreement whose primary purpose is locating or recovering unclaimed property is void and unenforceable if it was entered into during the period that begins on the date the property was presumed abandoned and runs until 24 months after the property is paid or delivered to the administrator. An agreement made outside that window still has to be in writing, signed by the owner, and has to disclose the property, the services to be performed, and the value of the property both before and after the fee. The owner or the administrator can also ask a court to strike compensation that is unconscionable, and the court may award attorney fees. If you have already signed with a finder, read that section before you pay anything.

The more serious concern is outright fraud. The Federal Trade Commission has warned about unsolicited calls, texts, and emails claiming you have unclaimed funds waiting and pressuring you to act fast, often by asking for an upfront "processing" or "release" fee, or for sensitive personal information out of the blue. No legitimate Montana agency will ask you to pay before it searches its own database or before it mails you money it already owes you. Report suspected scams at ReportFraud.ftc.gov.
