The questions that matter
Do I have to name a resident agent?
Every LLC must name a registered agent with an in-state street address.
The law: MCL 450.4207. go check legislature.mi.gov, last confirmed October 2026
Who's allowed to serve?
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.
Fit the rule and the role's yours at no cost.
What does an agent cost?
Agent prices on this page start at $99 to $149 a year, and three years of service come to $297 to $447.
Naming a different agent won't change any state fee.
Why does the state want one?
It takes delivery of lawsuits and official state mail for the LLC at an address in Michigan.
Mainstay Filing takes jobs the price actually covers, which counts 30%.
We run five tests: money out the door in three years (35%), jobs the price actually covers (30%), no hunting for the price (14%), no surprise at renewal (11%) and where it works (10%).
Add a state later and the same agent and price come along. MI Registered Agent.org stops at the Michigan line.
The last row is our math, not the state's: filing fee, plus the reports in years two and three, plus any minimum tax. If a cost has no fixed amount, like a newspaper notice, it's explained above and left out.
More questions
Can I be my own agent?
Yes, as long as you meet the state's rules on who can serve and on the address, both shown above.
Which addresses count?
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.
What do the picks cost over three years?
Mainstay Filing comes out at $447; MI Registered Agent.org comes out at $297; Michigan Registered Agent.co comes out at $297
Are the fees official?
Each state fee links to its official page, and each service price comes from the company's own site.
Do I have to use a service?
No. You can file with the state yourself. A service saves you time and can be your agent, but nothing makes you hire one.
Who's first in Michigan?
Mainstay Filing is first: it's $149 a year here and exactly the same in every other state. Then comes MI Registered Agent.org and Michigan Registered Agent.co.
