‹ 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. Here's the full cost.
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 | You owe $100 to $1,000 per calendar month. The exact amount is set by the court within this statutory range, but you cannot avoid the penalty by registering after the fact. | High |
| Back fees on cure | You owe every fee and tax that would have been due if you had registered on time. That includes registration fees, annual report fees, and franchise tax for each year unregistered. | 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 | Your contracts stay enforceable. Failing to register does not void any deal you signed, and the other party still owes you what they agreed to. | Low |
| Personal liability | Personal civil penalty exposure under state statute. Each member, manager, or employee who knowingly transacts business unregistered can be held personally liable, separate from the LLC itself. | High |
| State tax exposure | Possible. Michigan imposes corporate income tax, sales tax, and other state taxes on LLCs doing business in the state under separate Department of Treasury rules. Verify with the Michigan Department of Treasury. | Medium |
| How it gets enforced | State Attorney General can file suit to collect what you owe. AG offices actively pursue these cases. This is not a theoretical risk. | 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 Secretary of State for the standard filing fee. The application looks straightforward, but rejections are common. A wrong form version, a missing certificate of good standing from your home state, or a name conflict with an existing entity will bounce the filing and reset the clock by two to three weeks. Every week you stay unregistered is another week of penalty accrual.
Northwest reviews your application before it goes in, catches the rejection-causing mistakes (form version, name conflict, missing certificate of good standing), and submits same-day in most states. They'll also serve as your registered agent so the filing meets the statutory requirement on day one. If something is wrong, they fix it before the Secretary of State sees it, not after a rejection notice arrives three weeks later.
