Mississippi Certificate of Formation (2026)

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

A Mississippi LLC is created by filing a Certificate of Formation with the Mississippi Secretary of State for a $50 filing fee. Filing is done online through the Secretary of State's Business Services portal and is usually processed quickly. The certificate lists the LLC's name, its registered agent and office, and the organizer, and its acceptance brings the LLC into legal existence.

What Is a Mississippi Certificate of Formation?

The Certificate of Formation is the document that legally creates a limited liability company in Mississippi. It is Mississippi's name for what some states call Articles of Organization. Filing it with the Mississippi Secretary of State, and the state's acceptance of it, is the legal act that brings the LLC into existence under the Mississippi Limited Liability Company Act.

Until the certificate is filed and accepted, there is no LLC and no liability protection - the owners are operating as individuals or a partnership. Once accepted, the LLC is a separate legal entity that can own property, enter contracts, and shield its members' personal assets from most business liabilities.

This page focuses on the Mississippi formation document specifically. For the broader steps of starting an LLC - name, agent, EIN, operating agreement, and taxes - see how to form an LLC in Mississippi and the national formation guide.

Agency and Online Filing Requirement

You file the Certificate of Formation with the Mississippi Secretary of State, Business Services Division. Mississippi is notable for requiring formation filings to be submitted online through the Secretary of State's business portal rather than on paper. You create an account, complete the electronic certificate, and pay by card.

Online filing has advantages: it is faster, provides immediate confirmation, and reduces errors through built-in prompts. Processing is typically quick - often the same or next business day - compared with mailed filings in other states. You receive a stamped, filed copy you can download for your bank and records.

Because paper filing is generally not available for standard formations, plan to file digitally. If you need help, the Secretary of State provides guides in its Business Services section. A registered agent with a Mississippi address must be in place before you file, since the agent is named on the certificate.

Required Contents of the Certificate

The Certificate of Formation captures the core facts about the LLC. You must provide:

• The LLC name, which must include an LLC designator (such as "LLC" or "Limited Liability Company") and be distinguishable from other entities on file;
• The registered agent and registered office in Mississippi that will receive service of process and official notices;
• The name and address of the organizer filing the certificate;
• An email address for state correspondence and the effective date, if delayed;
• Any additional provisions the organizers choose to include.

Mississippi's certificate is relatively streamlined; detailed governance rules belong in the operating agreement, which the state does not file. Check name availability in the business entity search before filing so your certificate is not rejected for a conflicting name.

Accuracy at this stage matters because the certificate becomes the public legal record of your LLC. An error in the name, a registered agent who has not agreed to serve, or a missing designator can delay acceptance or require a corrective amendment later, which costs additional time and fees. Take a moment to confirm the exact spelling of the name, verify that your registered agent consents and has a valid Mississippi street address, and double-check the organizer information before you submit. Because the filing is electronic, most errors surface immediately, but a careful review up front is still the simplest way to get a clean, accepted certificate on the first attempt.

Filing Fee and Processing Time

The state filing fee for a Mississippi Certificate of Formation is $50, paid to the Secretary of State when you submit the online filing. This is the core cost of creating the LLC. Because Mississippi files formations electronically, processing is generally fast, and you typically receive confirmation quickly rather than waiting weeks.

Because fee schedules change, confirm the current $50 amount on the Secretary of State portal before filing. See the Mississippi LLC cost page for the full picture of formation and ongoing fees.

After Filing: EIN, Operating Agreement, and Taxes

Filing the certificate creates the LLC, but a few steps complete your setup. First, obtain a federal EIN from the IRS - it is free and needed to open a bank account, hire employees, and file taxes. See how to get an EIN in Mississippi.

Second, adopt an operating agreement. Mississippi does not require you to file one, but it governs ownership, management, and profit distribution internally and is important even for single-member LLCs. Third, register for state taxes with the Mississippi Department of Revenue if you will collect sales tax or have employees.

By default, the IRS taxes a single-member LLC as a disregarded entity and a multi-member LLC as a partnership, though either can elect S-corporation treatment. Finally, open a business bank account with your stamped certificate and EIN, keeping personal and business finances separate to preserve liability protection.

Ongoing Requirements and Name Rules

After formation, a Mississippi LLC must file an annual report with the Secretary of State to stay in good standing. For domestic LLCs this report is generally free but still mandatory, and it is filed online. Missing it can lead to administrative dissolution, so calendar the due date each year. See Mississippi annual report.

Your LLC name must remain distinguishable on the state's records and continue to include a proper designator. If you want to operate under a different brand, you can file an assumed name; see Mississippi DBA filing. Remember that an entity-name filing is not a trademark.

Keeping your registered agent current, filing the annual report, and paying any state taxes are the routine obligations that keep the LLC alive. The Certificate of Formation starts the entity; these ongoing steps maintain it. Governing rules appear in the Mississippi Limited Liability Company Act, Title 79, Chapter 29 of the state code.
