Strongest result
1. Registered Agent MS.org: best for Mississippi LLCs with limited funds
Formation $199; renewal $99 a year
Registered Agent MS.org reads highest, and the reason is that $199 above the state fee, with year-one agent service included, then $99 a year.
Mainstay Filing measures higher across three years, which puts this service first.
The price excludes the annual report, which the owner files every year.

2. Mainstay Filing: best for no annual report paperwork
$199 annually, state fee extra ($249 at checkout)
Mainstay Filing is an acceptable second choice: $199 per year performs the formation, keeps the registered agent and files the annual report; year two measures $199.
A gap of $200 to Registered Agent MS.org across three years fixes its position.
The service handles the annual report, and Mississippi bills no fee for it.
