Our score
9.4out of 10
9.4 out of 10
Our favorite is Mainstay Filing, because $199 gets the New Mexico formation done and covers a year of registered agent service, EIN application too.
New Mexico has no yearly LLC report, so after the first year your renewal pays for the registered agent and nothing more (year one also included your EIN application).
Over three years it costs $200 more than New Mexico Registered Agent.co, and for us the extra things it handles are worth that.

We took each price from the company's own pages on November 12, 2026. On top of every row, New Mexico charges a $50 filing fee, which isn't in these totals.
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 filings in the price.
New Mexico has no yearly report, so a bundle matters less, but one flat price with the EIN application included still gave Mainstay a small edge over New Mexico Registered Agent.co on coverage.
