$199 a year plus the state fee, $249 due at checkout

Top grade, Mainstay Filing: the formation filing, the registered agent and the annual report come to $199 a year, renewing at $199.

The renewal covers the annual report, which Mainstay files for you. Mississippi collects no fee, with a deadline of April 15; Mainstay passes the state's fee through at cost.

What decided the order

Of the grade, 32% rests on three-year bill and 32% on what the money buys; renewal handling, local rules match and pricing openness share the remaining 36%. What the money buys decided Mississippi.

Mississippi requires a report every year. Mainstay's price includes the filing and Registered Agent MS.org's does not, which outweighed Registered Agent MS.org's lower three-year cost in the coverage grade.
