Michigan’s MiBusiness Registry: One of the Most Open Company Registers in the US

How many companies are on the Michigan register?

The first question most people ask, answered straight from LARA’s own count. As of LARA’s published snapshot of 10 October 2025, the Michigan register holds roughly 3.20 million entity records across every type — corporations, LLCs, partnerships and nonprofits. Of those, about 1.18 million (37%) are currently in good standing; the other 2.02 million (63%) are not in good standing, dissolved, withdrawn, cancelled or expired. Put plainly: well under half of everything ever registered in Michigan is a live, compliant entity today — which is exactly why the free AR Standing field matters so much when you pull a record.

On the flow — how many open and close — the cleanest primary figure is federal: between March 2023 and March 2024, 25,756 Michigan establishments opened and 24,412 closed, a net gain of 1,344 (employer establishments; the count includes temporary closures and reopenings). Source: US Small Business Administration / US Census Bureau. Separately, new business applications — the leading indicator of formation activity — ran to roughly 148,000 in Michigan in 2023 on the US Census Business Formation Statistics series, the EIN-application measure that tracks intent to start a business rather than completed LARA registrations.

The layers of Michigan company data

Michigan's company data is more consolidated than most states' — the bulk of it sits in one place — but a complete KYB picture still spans a handful of systems. Knowing which body holds what saves wasted searches. Four sources matter.

A fifth source matters for Michigan's largest entities: SEC EDGAR, the US Securities and Exchange Commission's filing system at sec.gov/edgar. Michigan is home to some of the largest public companies in the country — the automotive majors and their listed suppliers — and a publicly-traded Michigan entity files audited financials and ownership disclosures with the SEC (the 10-K, 10-Q, and the DEF 14A proxy naming directors and major holders), all free. For listed entities, EDGAR carries the financial and ownership depth the state register doesn't. And one more, for the owners the register doesn't name: county clerk offices hold assumed-name and partnership records for sole proprietors and general partnerships, which do not register with LARA at all.

What the MiBusiness register actually gives you

Michigan's register is unusually generous for a US state, and knowing exactly which fields the free search surfaces is what lets you use it well. The key facts:

What sets Michigan apart is how much the free search actually returns. Open an entity record on the MiBusiness Registry and you get a working due-diligence picture, not just confirmation that a company exists:

• Identity and status, in full. Legal name, entity ID, entity type (profit corporation, LLC, LP, LLP, nonprofit), and the date of incorporation or organization — plus the current entity status (Active, Dissolved, Withdrawn). No login, no fee.
• AR Standing — a second, separate signal. Michigan shows an Annual Report Standing field alongside entity status. An entity can be “Active” in status yet “Not in Good Standing” for AR purposes if it has missed an annual filing. That two-field design is a genuine KYB gift: a lapsed AR standing is an early distress signal you can read directly, for free, before it escalates to administrative dissolution.
• The resident agent and registered office. Every Michigan entity must maintain a resident agent at a physical Michigan address for service of process; the register shows the current agent and office. As elsewhere, the agent is a point of contact, not an owner — but Michigan's advanced search also lets you search by agent or individual name, so you can map entities that share an agent.
• The full filing history. This is where Michigan goes beyond most states. The View Filings tab gives a chronological, downloadable trail of every public document — formation papers, amendments, name changes, annual reports/statements, mergers, and dissolutions. For a KYB analyst or investigator, that time-sequenced paper trail is the difference between a snapshot and an audit.
• Assumed names, on the same record. Active assumed names (DBAs) of a registered entity appear in the search with their own status, creation, renewal and expiration dates — and Michigan registers these at the state level through LARA, unlike most states where DBAs are filed county-by-county.

The one wall is the US-wide one. Michigan does not require LLC members or managers to be named in public filings, and there is no public beneficial-ownership register — so for the most common private form, the register confirms a great deal except who ultimately owns it. That is not a Michigan quirk; it is the standard US state limitation, and it is exactly where cross-jurisdiction ownership linkage earns its place. For multi-state KYB, Michigan pairs naturally with Delaware, Wyoming, and the other state registers covered in the US Secretary of State search guide.

Every Michigan company-data dataset, mapped

Across the LARA register, Michigan Treasury, the separate UCC portal and SEC EDGAR, thirteen datasets matter for KYB. Michigan's pattern is the mirror image of a privacy-first state: a wide free tier that does real due-diligence work, a thin band of paid items (only certificates and certified copies), and a small “not public” set that is the standard US limitation — LLC ownership and confidential tax data.

Exactly what data is free, paid & withheld

The free tier does the bulk of the work — identity, status, AR Standing, agent and the full filing history. Paid means only official certificates and certified copies. “Not public” means LLC ownership the state never collects and tax data that is confidential by law.

Dataset-by-dataset summary

The same data, viewed by source rather than access tier:

Eight free, two paid, three not public. Michigan's free tier does the real work — identity, status, AR Standing, resident agent, full filing history, assumed names, and name availability are all public at no cost, and for listed entities SEC EDGAR adds the financial layer. Only certified documents are paid. The “not public” set is narrow and is the standard US limitation: LLC ownership the state never collects, tax data held confidentially by Treasury, and UCC liens that live on a separate portal.

The Michigan company identifiers

A Michigan entity carries a small set of identifiers. The LARA entity ID resolves the register record; the federal EIN is the real operational key; and for listed entities, SEC and global identifiers carry the financial data the state record doesn't.

For production Michigan KYB, the entity ID resolves the state record and its filing history; the EIN is what the company actually transacts under, though it isn't a public search field; and for listed entities the CIK and Commission File Number unlock the SEC filings — financials, directors, major holders — that no state register carries. Michigan gives you a genuinely useful record on its own, and the federal identifiers extend it for the listed minority.

Worked example: Whirlpool Corporation

To anchor the identifiers and the LARA-vs-incorporation distinction in a real record, here is Whirlpool Corporation — one of Michigan's most recognisable companies, headquartered in Benton Harbor, yet legally incorporated in Delaware. It is the cleanest illustration of a point that trips up KYB analysts constantly: where a company operates is not where it is registered.

Three things the example surfaces. First, a household-name “Michigan company” can be a Delaware corporation — so a Michigan search returns it as a foreign qualification, and the charter sits elsewhere. Second, for a public company the financial and ownership depth is in SEC filings, not any single state register. Third, the distinction between a domestic Michigan entity and a foreign entity qualified in Michigan is the first thing to read off any LARA record.

For contrast, here is the kind of entity the MiBusiness Registry was built for — a domestic Michigan LLC, where the open register does real work:

The federal beneficial-ownership story — the fix that got rolled back

The one thing Michigan’s open register doesn’t give you — ownership — was, briefly, going to be solved at the federal level. That fix has largely been undone. Treated as a registry-data question — can you see who owns a Michigan LLC? — here is the current state, which has moved repeatedly and remains in flux.

The Corporate Transparency Act (CTA) took effect on 1 January 2024, requiring most US companies to report their beneficial owners to the Financial Crimes Enforcement Network (FinCEN) — a federal beneficial-ownership register that would, for the first time, capture the ownership data that states like Michigan don’t collect. It was never a public register (access was limited to authorities and, in narrow cases, financial institutions), but it was the most serious attempt in US history to collect ownership data that states deliberately don't.

Then it was rolled back. After a year of injunctions, stays, and reversals through the federal courts, FinCEN issued an interim final rule on 26 March 2025 that redefined “reporting company” to mean only entities formed under foreign law and registered to do business in the US. The practical effect: all entities created in the United States — including every domestic Michigan LLC and corporation — and their beneficial owners are now exempt from reporting BOI to FinCEN, and reporting companies need not report any US persons as owners. The federal layer that would have filled Michigan’s one ownership gap was, for domestic entities, switched off.

The story is not over, and that matters for how you treat it. The interim rule is not yet finalised; FinCEN has said it intends to issue a final rule, with a 2026 timeline now expected after delays. Federal courts — including the Eleventh Circuit — have upheld the CTA's constitutionality, so the statute remains valid law even though domestic reporting is currently suspended. In other words, it is premature to assume domestic entities will stay exempt. For KYB in 2026 the practical position is blunt: there is no working public or authority-facing federal ownership register for domestic Michigan entities right now, so confirming who owns a Michigan LLC means doing what analysts did before the CTA — building ownership from SEC filings (for listed entities), entity documentation, resident-agent and cross-jurisdiction records, and direct due diligence. (Status verified against FinCEN primary sources, June 2026; given the history, re-check the current rule before relying on it.)

Michigan’s economy — what the register reflects

Unlike a pure formation state, Michigan’s register largely describes a real, operating economy — which is part of why the data is worth reading closely. The state’s industrial base shapes the KYB picture: dense automotive and advanced-manufacturing supply chains mean layered supplier entities, joint ventures, and special-purpose vehicles. The numbers behind the register:

The contrast with the formation states is the point. Where a Delaware or Wyoming record is often a legal home for a business that operates elsewhere, a Michigan record more often describes an entity that actually does business in Michigan — and the register gives you the tools to read it: status, AR Standing, agent, and a full filing history, free. The one thing it won’t tell you is who ultimately owns a private LLC, which is where cross-jurisdiction ownership data does the remaining work.

API and bulk data feeds — the four real paths

For production KYB or onboarding integrations needing structured Michigan company data at scale, four access paths exist. LARA publishes no free high-volume company-search API — the routes are the MiBusiness portal, the SEC for listed entities, resident-agent data, and commercial providers.

Path 1 — The MiBusiness Registry portal

The search at the MiBusiness Registry supports free per-entity lookups by name, entity ID, agent, or individual, with partial-match and Soundex options and a full free filing history. It is the authoritative source, and unusually rich for a free portal — but it is built for human, per-entity searches, not high-volume programmatic querying, and the June 2025 migration changed URLs and login flows that older integrations relied on.

Path 2 — SEC EDGAR (for listed entities)

For Michigan’s publicly-traded entities — and the many large foreign-qualified ones operating in-state — SEC EDGAR is a genuinely rich, free, structured source: full-text search, per-filing APIs, and bulk data on financials, directors, and major holders. It only covers reporting companies, but for those it provides the ownership and financial depth no state register carries.

Path 3 — Resident-agent and reverse-agent data

Because every entity must name a resident agent, agent data is a useful relational signal. Michigan’s advanced search lets you query by agent or individual name directly — surfacing the set of entities sharing an agent, useful for mapping networks and clustering related entities, though it identifies the agent, not the owner.

Path 4 — commercial multi-jurisdiction APIs and bulk feeds

For teams that need Michigan alongside the other 49 states and 100+ countries with a consistent schema and real-time access, commercial providers ingest the LARA register, link entities to their filing history, resident-agent networks, and SEC filings, and re-expose them through one API — removing the per-portal friction and adding the cross-jurisdiction joins that resolve a Michigan LLC to its owners and a foreign-qualified entity to its home-state charter. Zephira’s Michigan data is sourced directly from the official register, with Data Provenance attribution on every field, and joined to all 50 US states, Canada, Mexico, and 100+ other jurisdictions on a single data model. Bulk delivery via S3 or SFTP is available for batch enrichment and offline analytics.

Michigan entity types — what each one means for KYB

Michigan offers the familiar US set of forms, and the register labels each one exactly as it appears in LARA’s data. Six categories account for almost all KYB-relevant records — and the domestic-vs-foreign distinction matters as much as the form itself.

When a Michigan entity lapses — penalties, dissolution and restoration

Given that more entities on the register are not in good standing than are, the lifecycle of a lapse is core KYB knowledge — it’s what the AR Standing field is quietly tracking. Here is what actually happens when a Michigan entity stops filing, and how it comes back.

Two practical points for due diligence. First, a lapse isn’t just a paperwork miss: losing good standing strips an entity of its authority to legally transact, so an “Active-but-Not-in-Good-Standing” counterparty is a real flag worth pausing on. Second, the filing history is the evidence trail — a restored entity shows the lapse and the restoration, so you can see not just the current state but the pattern of compliance over time. This is exactly why a free register that surfaces AR Standing and full history beats a thin one that only confirms an entity exists.

What the Michigan register doesn’t tell you

Michigan’s register is genuinely useful — but no state register is complete, and a few gaps catch out analysts who treat an open register as a finished one. The gaps that matter:

• Ownership is still invisible. For all its openness, Michigan does not require LLC members or managers in public filings and keeps no beneficial-ownership register. You get status, AR Standing, agent and full history — but not who ultimately owns a private LLC. Since the 2025 federal rollback, the FinCEN layer that would have captured it is switched off for domestic entities too.
• AR Standing and entity status are two different things. An entity can read “Active” in status yet “Not in Good Standing” on AR — a missed annual filing. Reading only one field misses the signal; an overdue AR is an early warning of possible administrative dissolution. The good news, unlike privacy-first states, is that both are free to check.
• The register is LARA, not the Secretary of State. Searching the Michigan Secretary of State for a business entity is a dead end — that office handles elections and driver services. Business records live at LARA’s CSCL Bureau. It’s a common, time-wasting confusion worth naming.
• Sole props and general partnerships aren’t here. They don’t register with LARA at all and receive no entity ID; their assumed-name records sit with county clerks. For those forms, the central register is silent.
• Tax and UCC data live elsewhere. Tax registration and returns are confidential with Michigan Treasury; UCC liens are on the separate ucc.michigan.gov portal. A complete check means leaving the business register for both.
• Private financials don’t exist publicly. Michigan requires no public financial filing from private entities. Unless a company is SEC-reporting, there are no accounts to find — only estimation, voluntary disclosure, or M&A documents.

Where the substance actually lives

Michigan’s register holds more than most, but a few layers sit in other systems. The practical map:

The practical takeaway: for a Michigan counterparty, the free register answers far more than most states — existence, status, AR Standing, agent, and the full filing history — certificates are a paid formality, SEC EDGAR covers the listed minority, and the one thing the register won’t give you is who ultimately owns a private LLC. That last gap is exactly where cross-jurisdiction linkage with clear provenance earns its place.

The ownership wall and sanctions risk

Michigan’s one real gap — private LLC ownership — is also where its only serious compliance exposure sits. An open register tells you a great deal about an entity, but the people behind a private LLC are exactly the data a US person is legally required to screen, and exactly the data the register doesn’t hold.

The OFAC 50 Percent Rule

The Treasury’s Office of Foreign Assets Control (OFAC) maintains the Specially Designated Nationals (SDN) List and a broader Consolidated Sanctions List — both free, official, downloadable, and searchable with fuzzy name-matching. US persons are broadly prohibited from dealing with anyone on them. The catch is OFAC’s 50 Percent Rule: an entity owned 50% or more, directly or indirectly, by one or more blocked persons is itself blocked — even if its own name never appears on any list. Because Michigan (like every US state) discloses no LLC ownership, that blocking interest can sit one or two layers up, exactly where the register shows nothing. Screening the entity name is necessary but not sufficient.

What this means for a KYB workflow

For a Michigan LLC, sanctions screening cannot stop at the entity name. The defensible approach is to screen the entity and every owner, manager, and connected party you can identify against the OFAC SDN and Consolidated lists — and, because the register won’t name those people, to source them from SEC filings (for listed entities), entity documentation, resident-agent clustering, and cross-jurisdiction ownership tracing. OFAC’s March 2026 Sanctions Advisory on “sham transactions and sanctions evasion” flags exactly this pattern — ownership concealed behind opaque US legal structures. The register’s openness helps you do the entity-level work; the ownership wall is the part that still demands cross-jurisdiction data.

Where Zephira sources Michigan data from — directly

The most important question for any Michigan company-data provider is the source. Zephira goes direct to the LARA register and links each entity to the records that hold what the register doesn’t — with source attribution on every field.

Every record carries a Data Provenance panel naming the specific official source and the timestamp of the last refresh. Where Michigan never collects ownership — LLC members and managers, beneficial owners — Zephira does not invent it; it traces what can be traced through SEC filings, resident-agent networks, and cross-jurisdiction linkage, and is explicit about what the public record cannot show.

Recent and ongoing developments

Two things shape the Michigan company-data landscape right now: a state-level platform change that already happened, and a federal ownership-reporting saga that is still unsettled. All dates verified from primary sources; given the federal volatility, re-check the current rule before relying on it.

Michigan registry activity — verified primary-source statistics

Two lenses on the Michigan register, both from LARA’s own published entity count as of 10 October 2025: the composition of the register by entity type, and the striking gap between entities in good standing and those that aren’t — the data point behind the AR Standing field.

Michigan registry data in regional context

How Michigan's access regime compares to other major jurisdictions:

Michigan sits at the open end of the US spectrum. Like every US state it has no federal register and collects no LLC ownership — but among states it is unusually generous, surfacing status, AR Standing, resident agent and a full filing history for free and with no login, where Delaware gates status behind a fee. It still falls short of the UK, which publishes directors, accounts and beneficial owners for free. For KYB the practical reading is encouraging: a Michigan entity is easy to confirm and to assess — you can see whether it’s live and compliant without paying — and the one remaining gap, private LLC ownership, is the standard US one that cross-jurisdiction linkage is built to close.
