Paperwork covered, worth 29%, put Mainstay Filing first.
Five tests set the order: three-year price (36%), paperwork covered (29%), straightforward pricing (15%), renewal behavior (10%) and states served (10%).
Only the first pick works in every state, which counts the day the LLC registers elsewhere.
The final row is a sum, not a state figure: filing fee, then years two and three of reports, then minimum tax where it applies.
Other questions
Do I have to pay an agent?
You can once you fit the rule. Owners often still hire a service to keep a home address off the record.
Which address counts?
The address has to be a street address in New Mexico. P.O. boxes are not accepted.
After three years, what has each cost?
$447 for Mainstay Filing, $297 for NM Registered Agent.org, $297 for New Mexico Registered Agent.co
Are the fees official?
Official New Mexico documents supply the state fees, and the companies' own price pages supply the service fees. Every figure carries a date.
Does the law require a service?
Nothing requires it. Think of a service as paid convenience.
Who is your first choice in New Mexico?
Mainstay Filing leads because the $149 yearly price follows the company to any state it adds; NM Registered Agent.org and New Mexico Registered Agent.co come next.
