The Michigan Department of Treasury holds the state's unclaimed property, and its explanation of the programme sets out what that covers and what it does not: abandoned financial assets such as checking and savings accounts, unpaid wages, securities, life insurance payouts, uncashed checks and the contents or proceeds of safe deposit boxes, left without activity for a certain period, and not real estate. The organisation holding the asset is expected to try to reach the owner first and to establish activity through an online login, written correspondence, a withdrawal or deposit or an update to personal information, and only where that fails is the asset reported to the state of the owner's last known address. Michigan describes unclaimed property law as a consumer protection programme that has grown to protect owners, heirs and estates alike, says that outreach through mailings, advertising and local media begins once property arrives, and makes the promise that matters most: the state keeps custody in perpetuity until the rightful owner or heirs come forward.
The scale is set out in the Treasury's own announcements. The programme's front page reports more than $675 million returned in the last five years; the Treasury's January 2026 release puts the most recent year at $164 million, while the Governor's February 2026 proclamation of Unclaimed Property Day gives the figure for the last fiscal year as more than $163 million, and the same proclamation states that Michigan holds over $2 billion and over 20 million accounts waiting to be returned. Terry Stanton, who oversees the programme, makes the practical point that the database is updated multiple times throughout the year, so a search that found nothing last year is worth repeating. Post goes to Michigan Unclaimed Property, P.O. Box 30756, Lansing, MI 48909, couriers to the Operations Center at 7285 Parsons Drive, Dimondale, the claims line is 517-636-5320 and the reporting line 517-636-6940.

- No deadline: the Treasury takes custody of the property and it stays claimable by the owner or the heirs in perpetuity, so an old record is not a lost one.
- Search: the Treasury database, free, by last or business name with a first name optional and a city or postcode to narrow a long result list.
- Dormancy: three years for most property types, one year for uncashed payroll checks, and one year for every property type held by a government entity.
- Holders: the annual report is due on the first business day of July for property that reached dormancy at the previous March 31.

The four steps of a Michigan claim
The claiming guide breaks the process into searching for property, submitting a claim, completing it and tracking its progress, and it is specific about the first step because that is where most searches go wrong. A name goes into the last name or business name field, with the first name optional, and if the result list is too long the search is narrowed by adding a city or a postcode. The properties that look right are selected with the claim button and the claim begins.
The Treasury adds advice of its own in its public notices: search a maiden name as well as a current one, and search the name of a business or a nonprofit, because organisations lose money exactly as people do. Two tools sit on the front page for a claim already filed, a claim status search that takes the claim identifier and an upload page for submitting documents to an existing claim, which is the route the Treasury prefers over the post.
There is never a charge to search for or to claim property, and the claims line answers between 9 a.m. and 2 p.m. on weekdays.
Dormancy, and how to stop property becoming unclaimed
Property becomes reportable when there has been no activity for the dormancy period and the business holding it cannot find the owner. Michigan uses three years for most property types, one year for uncashed payroll checks, and one year for every property type where the holder is a government entity, with the full table published as Appendix A of the reporting manual. The general questions page turns that into advice for owners: make a deposit or withdrawal at least once a year so the account shows activity, cash every check received without delay including cashier's checks and money orders, answer a due diligence letter or notice of abandoned property by its due date rather than treating it as junk mail, tell the companies holding property about every change of address, and tell a family member or another trusted person where the financial records, bank accounts and safe deposit boxes are.
The second of those is the one that costs the most money in practice, because a payroll check left uncashed is only a year away from the state.
What the law asks of businesses
Michigan's Uniform Unclaimed Property Act, Public Act 29 of 1995 as amended, requires businesses and government entities to report and remit abandoned property belonging to owners whose last known address is in Michigan, and it requires every business or government entity incorporated in Michigan to report property where no address is known at all. The Treasury notes that most businesses have unclaimed property arising from normal operations, naming uncashed payroll checks, vendor checks and accounts receivable credit balances as the usual sources.
The reporting page fixes the calendar: the annual report is due on the first business day of July for property reaching its dormancy period as of March 31 that year, and the recommended run up has the holder identifying reportable property by March 31, preparing and posting due diligence letters to inactive owners by April 15, working out by May 15 who has not responded, and beginning the report on June 1 using reporting software or the free upload on the Treasury site.
A holder that fails to file properly faces interest at one percentage point above the adjusted prime rate per annum per month on the property from the date it should have been delivered, and a penalty of 25 percent of its value.
The reporting details that catch holders out
The same page carries the current file and coding rules, which change more often than the deadlines. Reports are accepted as NAUPA II files with a .hrs or .txt extension; files with a .hde extension and reports in the older NAUPA I format are not accepted. A holder reporting an individual retirement account must first withhold tax in line with the Internal Revenue Service's Revenue Ruling 2018-17 and then use the standard deduction code TW to document the tax withheld while reporting the net balance.
Contingent beneficiaries named on insurance policies are coded BC, with primary beneficiaries still coded BF, and the old and or relationship code AO is no longer accepted, so multiple owners on one property must each be reported with their own relationship code from the list in Appendix C. Securities reporting has changed in several ways and has its own manual. Entities domiciled, incorporated or doing business in Michigan with nothing to report are strongly encouraged to file a zero or negative report to establish a filing history, with one exception, mutual funds, which should not file one.
A holder that never reported, or under reported, can sign the voluntary disclosure agreement on Form 4869, under which it files and remits for the current reporting year and the previous four within six months of filing the form and is not assessed penalties or interest.
Reading a Michigan result
A record in the Treasury database is an asset a company gave up after its own attempts to create activity failed, filed under the name and address it held at the time, which is why a maiden name, an initial and an old city are all worth trying, and why a result that looks slightly wrong is often right. Nothing expires here. The Treasury holds the property as custodian and returns it to the owner or the heirs whenever they come forward, which makes an unsuccessful search today worth repeating after the next reporting round in July, when the year's new property lands.
A claim costs nothing at any stage, so a letter offering to recover Michigan money for a share of it is selling something the state gives away.
