Our score

9.4out of 10

9.4 out of 10

Our favorite is Mainstay Filing, because $199 gets the New Mexico registration filed, year one as registered agent costs nothing, and after that it's $149 a year.

Year one as agent costs nothing; every later year is $149, in any state.

Over three years it costs $100 more than NM Registered Agent.org, and for us the extra things it handles are worth that.

In New Mexico, filings in the price decided the order. If you're curious about the weights, three-year cost is 29%, filings in the price is 29% and renewal price, state fit and up-front totals share 42%.

Registering in a second state means working with two states, so one company at one price for both won the coverage score over NM Registered Agent.org.
