Why Mainstay Filing is first
The Founders Review weighs five things, led by three-year cost and what one price covers at 30% each. For New Mexico, what one price covers is what separated first place from second.
Mainstay Filing's plan covers more per dollar on our coverage criterion: same-day scanning of legal papers at no fee, three free mailing scans a year and one price in all fifty states. New Mexico Registered Agent.co wins on cost, and its score sits close behind.
Our method page lists all five criteria.
What New Mexico requires of a registered agent (official rules)
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 statute is NMSA 1978, § 53-19-5.
Yearly paperwork
New Mexico skips the yearly report; keeping a registered agent on file is still required.
