‹ Michigan Filing Guide · All Penalties
Operating in Michigan without a certificate of authority can trigger a civil penalty under state statute and bar your LLC from Michigan courts. See the consequences and next steps below.
Michigan stacks penalties hard. You owe $100 to $1,000 per calendar month for up to 5 years of unregistered operation (entity cap $10,000), PLUS a separate $10,000 cap per individual manager, member, or authorized person who participated. You also owe back fees, you can't maintain any action in Michigan courts until you register, and the court will issue an injunction barring further business until you pay every penalty and obtain the certificate of authority.
| What's at stake | If you don't register | Severity |
|---|---|---|
| Civil penalty | $100 to $1,000 per calendar month for up to 5 years, capped at $10,000 for the entity, plus a separate $10,000 cap per individual manager, member, or authorized person who participated. Registering now does not necessarily remove a penalty for earlier activity.Checked Sep 26, 2026 · legislature.mi.gov | High |
| Back fees on cure | You owe every fee and tax that would have been due if you had registered on time. Applicable charges include registration fees and annual report fees, following each charge's own filing schedule. A one-time registration fee is not charged again for every unregistered year. | High |
| Right to sue in state court | Closed. You cannot bring or maintain any lawsuit in state court until you register. If you need to sue a customer, a partner, or a vendor, you have to register first. You can still defend yourself if someone sues you. | High |
| Contract validity | Contracts generally remain valid, but registration may be required before you can sue to enforce them. | Low |
| Personal liability | Individuals involved in doing business without registration can face a separate civil penalty. The statute below identifies who is covered and the conditions. This is separate from liability for the LLC's debts. | High |
| State tax exposure | Possible. Michigan corporate income tax applies to an LLC taxed federally as a C corporation. An LLC taxed as a partnership or S corporation is a flow-through entity and does not pay it. Other filing and payment duties, such as sales tax, may still apply. | Medium |
| How it gets enforced | The Attorney General can bring enforcement proceedings under the cited statute. Timing and outcomes depend on the case. | N/A |
Here's how to fix it before any of this catches up to you.
You can file the foreign qualification yourself directly with the Michigan Department of Licensing and Regulatory Affairs for the standard filing fee. A wrong form version, a missing certificate of good standing from your home state, or a name conflict with an existing entity can delay approval. Check the form and required documents before submitting. The consequences of remaining unregistered are described above; they do not all accrue weekly.
File it yourself$50 + $125 = $175, the state fee plus a registered agent for the year
Have Northwest file it$50 + $225 = $275, the state fee plus the service, one year of registered agent included
These totals cover registration and the listed service only. Back fees, penalties, taxes and required attachments are extra. The DIY example includes a paid agent. State fees paid by card through Northwest carry a 2.7% card charge. Both routes leave you with the same registered agent obligation from year two.
Want help with the paperwork? Northwest can prepare and submit your foreign registration and serve as your registered agent. Hiring a service does not erase overdue fees, taxes or penalties.
