Opened up, question by question

When must an out-of-state LLC register here?

Registration sits at the front of the line for an out-of-state LLC heading into Michigan.

Inside the risk of skipping it: Michigan's courts stay closed to it as a plaintiff until it registers (MCL 450.5007(1)).

peek at michigan.gov, confirmed October 2026

What is inside the cost of registering?

The state charges $50, and a service adds $199.

Over three years the state's fees reach $100, counting any recurring report. peek at legislature.mi.gov, confirmed October 2026

What registers the LLC?

Your LLC is registered when the Michigan Department of Licensing and Regulatory Affairs (LARA), Corporations Division accepts the Application for Certificate of Authority to Transact Business in Michigan (for foreign limited liability companies) (Form CSCL/CD 760).

Attach certificate of good standing issued within the last 30 days.

Is there a filing that repeats?

Next in the box: the annual statement, at $25.

The state frames the deadline as February 15.

Also worth asking

Does the home state need its own agent?

Yes. Think of two separate rule books, your home state's and this one's. Mainstay Filing works in both, so a single account can serve the pair.

What do the picks cost over three years?

Michigan Registered Agent.co stacks up to $397, Mainstay Filing stacks up to $497, MI Registered Agent.org stacks up to $397, before state fees.

What do these numbers rest on?

The state-side figures were taken from Michigan's own publications, and the service prices from the price page each company posts. Dates for both appear on this page.

Does the law require one?

No. Owners can file with the state directly. A service saves time and can act as agent, but nothing makes you hire one.

Will a service file the registration for me?

Each company here handles the filing itself. What differs between them is only the service fee, since the state charges the same.

Which foreign registration service should I open first in Michigan?

Michigan Registered Agent.co is on top: registering costs $199 over the state fee, with the agent covered in year one, then $99 a year. Under it sit Mainstay Filing and MI Registered Agent.org.
