Service Year one Year two Year three Bill over three years Price holds on renewal
Mainstay Filing $149 $149 $149 $447 Yes

Why it falls this way

Here is the weighting: 33% for spend over three years, 33% for work the price removes, 34% spread over what renewal looks like, fit with the state and plain price display. In Michigan, work the price removes made the call.

Mainstay's agent plan brings more to the table: served papers are scanned the same business day for nothing, one price in all fifty states and three government mailings a year scanned free. MI Registered Agent.org is cheaper, and it was close.

The full criteria and weights are on How we rank.

Michigan resident agent rules straight from the Department of Licensing and Regulatory Affairs (LARA) (official)

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 behind it: MCL 450.4207.

Michigan's annual statement: what it costs, when it is due, who gets the notice

Michigan LLCs send in the annual statement every year, due February 15. The state's fee is $25. Send it late and $10 gets added. Notices about it land with your resident agent.

Michigan registered agent: reader questions

Do you need a resident agent to run a Michigan LLC?

You do. Michigan wants a resident agent on file for every LLC, and the agent must have a street address in the state.

What should you expect to pay a Michigan registered agent?

Plan on $99 to $149 a year, and the price holds when it renews.

Could you serve as your own resident agent?

You can if the state's rules allow it. 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 does the Michigan annual statement have to go in?

Get it in by February 15. The state's cut is $25. Miss the date and it costs $10 more.

Mainstay Filing ($149 a year), MI Registered Agent.org ($99 a year) and Michigan Registered Agent.co ($99 a year), best pick first.
