3 Best LLC Services in Mississippi (2026)
1. Mainstay Filing: best for formation, agent and annual report on a single line
$199 a year plus the state fee, $249 due at checkout
Mainstay Filing is rated first: $199 a year includes the formation filing, the registered agent and the annual report; renewal is $199.
Mainstay files the annual report at each renewal. The state charges nothing, due April 15, and Mainstay passes that fee on at cost.

What decided the order
Weights: 27% cost over years one to three, 27% inclusions per price, 46% shared by renewal price and terms, fit with state rules and price clarity. Inclusions per price decided Mississippi.
Mississippi requires a report annually. Mainstay's amount covers that filing while Registered Agent MS.org's does not, so coverage outweighed Registered Agent MS.org's lower three-year sum.
