Forming an LLC in Mississippi — the version your lawyer doesn't want you to read

Forming a Mississippi LLC is a sixty-minute job for a moderately attentive adult. The state's filing portal is competent, the filing fee is $50, and the Certificate of Formation is one page with maybe six fields on it. The reason every lawyer in Oxford will quote you $1,500 to do this is that they're charging you for the operating agreement, the EIN application, and the corporate-record binder — not the filing itself. This guide walks through the whole sequence so you know what you're paying for if you hire someone, and so you can do it yourself if your situation is simple enough.

Start with the name. Mississippi requires the words 'Limited Liability Company,' 'LLC,' or 'L.L.C.' in the name and prohibits anything that implies a banking, insurance, or government function without specific authorization. Run the proposed name through the Secretary of State's business search before you do anything else — if a near-match exists, you'll get a rejection and a refund-less rejection at that, which is a great way to start the morning.

Next, pick a registered agent. This can be you, if you have a Mississippi street address (no P.O. boxes) and you're going to be there during business hours to receive service of process. It can be a commercial registered agent service for $50–150/year. It cannot be the LLC itself. For most single-member operators with a stable address, naming yourself is fine. For operators who travel, who don't want their home address public, or who run multiple entities, a commercial agent is worth the money.

File the Certificate of Formation on sos.ms.gov. Fields: name, registered agent, principal office address, name and address of organizer, effective date (usually 'on filing'), and your signature. Pay the $50. You'll get a stamped Certificate back in 24–72 hours.

Pull the EIN from the IRS directly at irs.gov. Free. Five-minute online form. Do not pay one of the upsell sites $79 for this. They are typing the same SS-4 you would type, except slower and with worse customer service. The EIN comes back instantly.

Now the part most people skip and shouldn't: the operating agreement. Mississippi doesn't require LLCs to have one, but every bank, every investor, every future partner, and every IRS auditor will ask for it. A single-member operating agreement is largely off-the-rack — it confirms member control, distribution mechanics, dissolution, and successor management. A multi-member operating agreement is the most important document in your business and absolutely should not be the three-page template the legal-tech sites sell.

Once you have the stamped Certificate, the EIN, and an operating agreement, take all three to the bank and open the LLC's bank account. Do not commingle. Do not pay personal expenses from the LLC account. Do not pay LLC expenses from your personal account except in genuine emergencies, and then reimburse promptly. This is where the limited-liability shield gets pierced in most small LLC disputes — not because the formation was wrong but because the operator treated the LLC as their personal checkbook.

Last, decide on tax treatment. Default for a single-member LLC is disregarded entity — the LLC files no separate federal return and the income flows to your Schedule C. Default for multi-member is partnership — Form 1065 with K-1s to members. You can elect to be taxed as an S-corp using Form 2553, which is sometimes worth it once you're consistently profitable above roughly $50K in net distributions. It is rarely worth it below that, because the cost of running real payroll and the extra return preparation eats the savings.

When you actually need a lawyer: multi-member LLCs with anything but the simplest split; LLCs holding real estate that needs to be assigned in; LLCs anticipating outside investment; and LLCs where the members are family members and you want to head off the inevitable future fight with terms you all agreed to while you still liked each other.
