Our favorite is Mainstay Filing, because it's $149 a year and the price doesn't climb at renewal, plus papers served on the company get scanned the same business day for free.
Starting from scratch? The $199 yearly package adds the Michigan filing and the annual statement.
Over three years it costs $150 more than Michigan Registered Agent.co, and for us the extra things it handles are worth that.

What Michigan says about the resident agent (via the Department of Licensing and Regulatory Affairs (LARA))
Every LLC must name a registered agent with an in-state street address. The address has to be a registered office in Michigan, which does not have to be the place of business. P.O. boxes are not accepted. The law: MCL 450.4207.
The Michigan annual statement: when and how much
Here's the schedule: the annual statement is due every year in Michigan, by February 15. It costs $25. If you're late, add $10. Reminders from the state go to your resident agent.
Your questions about Michigan registered agents
Do I really need a resident agent for a Michigan LLC?
You do. Michigan won't accept an LLC without a resident agent who has a street address in the state, and that name goes on the public record.
What do Michigan registered agents usually cost per year?
Plan on $99 to $149 a year, and each service keeps its price when you renew.
Can I be my own resident agent?
Sometimes, if you meet the state's rules. A Michigan resident, or a corporation or LLC formed in Michigan or authorized there, whose business office (or, for a person, residence) is the registered office.
When do I have to send in the Michigan annual statement?
Mark February 15 on your calendar. The state's charge is $25, and sending it late tacks on $10.
Which registered agents did we review here?
Mainstay Filing ($149 a year), Michigan Registered Agent.co ($99 a year) and MI Registered Agent.org ($99 a year), with our favorite first.
Who is the best registered agent for Michigan?
Mainstay Filing, because one plan, $149 a year, follows the company to any state and renews at $149.
