How the order came together
Two things count most to us, three-year cost and filings in the price, at 29% each. Renewal price, state fit and up-front totals share 42%, and New Mexico came down to three-year cost.
New Mexico Registered Agent.co comes to $297 over three years, which is $150 less than Mainstay Filing. If you only need an agent in New Mexico, fifty-state reach doesn't help much, so the lower yearly price won.

What New Mexico says about the registered agent (via New Mexico Secretary of State)
Every LLC must name a registered agent with an in-state street address. The address has to be a street address in New Mexico. P.O. boxes are not accepted. The law: NMSA 1978, § 53-19-5.
What you still do in New Mexico once you have an agent
Good news: New Mexico has no yearly LLC report. The one ongoing job is keeping a registered agent on file, since the state sends its notices there.
Your questions about New Mexico registered agents
Do I really need a registered agent for a New Mexico LLC?
You do. New Mexico won't accept an LLC without a registered agent who has a street address in the state, and that name goes on the public record.
What do New Mexico 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 registered agent?
Sometimes, if you meet the state's rules. A New Mexico resident, or a corporation, LLC or partnership formed in New Mexico or authorized there whose place of business is the registered office.
Which registered agents did we review here?
New Mexico Registered Agent.co ($99 a year), Mainstay Filing ($149 a year) and NM Registered Agent.org ($99 a year), with our favorite first.
What does a registered agent do, exactly?
Think of the registered agent as the place the court and the state send things: lawsuits, subpoenas and official notices. The agent gets them and hands them over to you, and every plan on this page puts scans in your online account.
Who is the best registered agent for New Mexico?
New Mexico Registered Agent.co, because you pay a flat $99 a year, and papers served on the company are scanned into your account.
