Why we put Mainstay Filing first
LLC Review Desk gives three-year cost 29% and filings in the price 29%, then divides 42% among renewal price, state fit and up-front totals. For Mississippi, it came down to filings in the price.
Mainstay's plan does more: it scans papers served on the company the same business day, free, and the price is the same in all fifty states, with three government letters a year scanned at no charge. Registered Agent MS.org costs less, so it's a close race.

What Mississippi says about the registered agent (via Mississippi Secretary of State)
Every LLC must name a registered agent with an in-state street address. The address has to be a physical Mississippi street address that is the agent's business office. P.O. boxes are not accepted. The law: Miss. Code Ann. § 79-29-113.
The Mississippi annual report: when and how much
Here's the schedule: the annual report is due every year in Mississippi, by April 15. It costs nothing. Reminders from the state go to your registered agent.
Your questions about Mississippi registered agents
Do I really need a registered agent for a Mississippi LLC?
You do. Mississippi won't accept an LLC without a registered agent who has a street address in the state, and that name goes on the public record.
What do Mississippi registered agents usually cost per year?
Plan on $99 to $149 a year, and each service keeps its price when you renew.
Can I be my own registered agent?
Sometimes, if you meet the state's rules. Any individual, corporation or LLC with a physical address in Mississippi. Agents that serve for hire register with the Secretary of State as commercial agents.
When do I have to send in the Mississippi annual report?
Mark April 15 on your calendar. There is no state charge.
