Straight answers

How much should I set aside to form it?

Add the state's fees from filing through year three: $50. sos.ms.gov, confirmed August 2026 (official)

What do I file and who gets it?

The Mississippi Secretary of State receives the Certificate of Formation (Form F0100), and approval is what forms the company.

Statute: Miss. Code Ann. § 79-29-201. sos.ms.gov, confirmed August 2026 (official)

Could I file this on my own?

Yes, you can. On your own you'd owe just the state's fees, which come to $50 over three years.

Using a service lifts your three-year bill by $397 to $597.

Why is the list in this order?

It comes down to work taken off your hands, and Mainstay Filing is best at it.

We start with cost across three years, move to work taken off your hands, and finish with three smaller checks.

One thing decides it: the annual report is in the first pick's price, while Mississippi Registered Agent.co leaves it to you.
