Mississippi Articles of Organization (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

In Mississippi, you form an LLC by filing a Certificate of Formation - the state's equivalent of articles of organization - online with the Secretary of State for a $50 fee. The filing names the LLC, its registered agent, and principal office, and Mississippi's annual report is free.

What the Mississippi Certificate of Formation Is

The Certificate of Formation is the legal document that creates a limited liability company in Mississippi. Mississippi law calls this document a Certificate of Formation, which serves the same role as the "articles of organization" used in many other states. You file it with the Mississippi Secretary of State, and the state's acceptance of the filing is the moment your LLC legally comes into existence under the Mississippi Limited Liability Company Act. Before that filing, the business has no separate legal identity or liability shield.

Think of it as the LLC's birth certificate: it is short, but it is the foundational public record of the company. It is different from an operating agreement, which is the internal contract among members and is not filed with the state. This guide explains what the Mississippi document must contain, what it costs, and how to file it. For terms, see the glossary.

What the Mississippi Certificate of Formation Must Contain

Mississippi law specifies the minimum contents. The document generally must state the LLC's name (including a required designator such as "LLC" or "Limited Liability Company"), the name and address of its registered agent and registered office, the principal office address, and whether the LLC is member-managed or manager-managed.

It also names the organizer who signs and submits the filing, and may state a specific effective date and the LLC's duration if not perpetual. The name must be distinguishable from existing entities - run a Mississippi business entity search first. Some states ask for the business purpose, though a general-purpose clause is usually enough. Getting these details right the first time avoids rejection and re-filing.

Filing Fee and Methods in Mississippi

The state filing fee for the Certificate of Formation is $50, paid to the Mississippi Secretary of State. Mississippi requires LLC formations to be filed online through the Secretary of State's business portal. Online filing is the fastest route and is typically processed within a few business days; mailed filings take longer.

You pay the fee when you submit the document. Optional extras - expedited processing, certified copies, or a name reservation before you file - carry separate fees on the Mississippi Secretary of State schedule. Compare the total cost of formation, ongoing reports, and registered agent service on our Mississippi LLC cost page. The EIN you get afterward from the IRS is always free.

The Registered Agent Requirement

Every Mississippi LLC must name a registered agent on the Certificate of Formation and maintain one continuously afterward. The agent must have a physical street address in Mississippi - the registered office - and agree to receive service of process, tax notices, and official state mail for the company.

The agent can be an individual Mississippi resident, a manager or member, or a commercial registered agent service. You may serve as your own agent if you meet the address and availability requirements, but many owners use a service for privacy and reliability. If the agent or office changes after formation, you file the state's change-of-agent form. Our national registered agent overview explains the role in depth.

After You File: Next Steps

Once the Mississippi Secretary of State accepts your Certificate of Formation, complete the setup that makes the LLC operational. First, adopt an operating agreement - even a single-member LLC benefits from one, and it governs ownership, voting, and profit distribution even though Mississippi does not file it. Next, obtain a federal EIN from the IRS, which is free and needed to open a bank account and hire.

Then register for Mississippi taxes and any licenses your activity requires, and open a dedicated business bank account to preserve your liability shield. Understand your ongoing obligations, discussed next, so the LLC stays in good standing. Review federal tax choices, including a possible S-corp election, on our business tax pages.

Keeping the Mississippi LLC in Good Standing

Forming the LLC is the start of an ongoing relationship with the state. Mississippi LLCs must file an annual report with the Secretary of State by April 15 each year; for domestic LLCs the report is free. You must also keep your registered agent current and file your federal and Mississippi tax returns. Falling behind on the report or agent is the most common cause of losing good standing and can lead to administrative dissolution.

If the LLC's information changes - a new address, member, or manager - update the record with the Mississippi Secretary of State through an amendment. When you eventually wind down the business, file the proper termination documents rather than abandoning the entity; see our how to dissolve an LLC in Mississippi guide for the closing steps and final tax returns.

Verify Current Details and Avoid Common Pitfalls in Mississippi

State fees, tax rates, forms, and deadlines change from year to year, so before you file or pay anything, confirm the current figures directly on the official Mississippi agency websites cited below. The amounts on this page are effective for 2026 and are set by the government, not by any filing service. Public records and most state forms are free or low-cost, and a federal EIN is always free from the IRS - be cautious of third-party websites that charge inflated fees to file routine state paperwork or to obtain a number the government issues at no cost. Reading the primary source yourself is the surest way to avoid outdated or misleading second-hand information, which is exactly why every figure here links to a Mississippi agency, statute, or the IRS.

A second common pitfall is blurring the line between you and your business. If you operate through an LLC or corporation, the liability protection depends on treating the entity as genuinely separate: keep a dedicated business bank account, sign contracts in the company name, keep clean records, and adopt an operating agreement even if Mississippi does not require you to file one. Commingling personal and business money is the fastest way to weaken the shield if the company is ever sued. Owners should also plan for taxes early - set aside money for income and self-employment tax, and review whether an S-corp election fits once profits grow. See our business tax overview for how the pieces connect.

Finally, do not confuse a state business registration with trademark ownership. Clearing a name in the Mississippi business entity search means no other registered entity has that exact name - it does not grant nationwide rights or clear a federal trademark, so search the USPTO database before you invest in branding. Likewise, if you use a name different from your legal entity name, file a Mississippi DBA. When your business changes or winds down, follow the proper Mississippi dissolution steps rather than simply abandoning the entity, which leaves fees and filings running.
