Mississippi LLC Cost: $50 to File Certificate (2026)

Fact-checked and updated September 14, 2026.

A Mississippi LLC costs $50 to file a Certificate of Formation (Form F0100) with the Secretary of State. The annual report (F0108) is $0 and is due by April 15 each year (online only). File on the SOS business portal or use ZenBusiness Starter for a $0 formation service fee plus the same $50 state fee. Optional services cost extra.

This page is for founders forming a domestic Mississippi LLC online, including the $50 Certificate and the $0 April 15 annual report that still must be filed to stay in good standing.

This guide is for creating a new Mississippi LLC. If you already have an LLC formed in another state, check Mississippi’s foreign-entity registration requirements before creating a second company.

Mississippi LLC costs: required fees and optional extras

Start with the Mississippi SOS fee schedule PDF and the annual reports page.

Budget example: $50 to form plus a free April 15 annual report is a low SOS cash outlay—before tax accounts, insurance, or local licenses. Mississippi requires online filing for business documents. All Mississippi business documents file online; there is no parallel paper Certificate channel on the modern portal. Budget time to register a username before you intend to form the company.

No SOS franchise tax is identified for domestic LLCs. Department of Revenue obligations are separate. A $50 Certificate and $0 annual report look inexpensive, but portal outages and Business ID lookups still create friction. Keep your Business ID and login credentials in the company records folder. Foreign LLC registration uses different forms and higher fees than a domestic Certificate of Formation. If your company already exists in another state, read foreign-registration instructions instead of filing a second domestic LLC by mistake.

Should you file on the Mississippi SOS portal or use ZenBusiness?

Choose DIY if you can create a SOS filing account, complete the Certificate, and calendar April 15. Choose a filing service for guided preparation. A $50 Certificate and $0 annual report look inexpensive, but portal outages and Business ID lookups still create friction. Keep your Business ID and login credentials in the company records folder. Read renewal and cancellation terms for any optional compliance product before you pay.

ZenBusiness lists Starter at $0 without a base-plan renewal. Its optional first year of Worry-Free Compliance renews at $199/year; registered-agent service is listed at $199/year (intro pricing may show about $99 for the first year—confirm at checkout). EIN and operating-agreement services are separate Starter purchases. Check the current package terms and checkout selections.

A free introductory service can become a recurring expense. Before paying, review the initial total, renewal amounts, and cancellation terms. Keep a copy of your selections. A reminder is not confirmation that a required state filing was submitted, and the state filing fee remains separate.

Can you be your own Mississippi registered agent?

Yes, if you maintain a Mississippi street address for service of process and meet SOS registered-agent rules. A member may serve when those conditions are met.

If you cannot reliably receive legal documents in Mississippi, use a commercial agent and compare renewal terms.

Plan addresses before filing. SOS records are public—enter accurate agent and office information.

Registered-agent changes use SOS forms with modest fees (commonly $10 on the fee schedule). Update promptly if the agent or office address changes.

How to file your Mississippi LLC: a practical checklist

1. Create a filing account on corp.sos.ms.gov (Mississippi requires online filing).
2. Check the name and include an LLC designator. Optional reservation is $25.
3. Appoint a registered agent with a Mississippi street address and obtain consent.
4. File Certificate of Formation (F0100) and pay $50. Payments are nonrefundable.
5. Confirm acceptance, save your Business ID, and calendar the $0 annual report due April 15.

How long does approval take?

Processing depends on the SOS online system. ZenBusiness preparation time (often listed at 7–10 business days) is separate from Mississippi’s acceptance. Leave buffer for name issues and portal outages. Payments to the Mississippi SOS for business filings are nonrefundable. Double-check the name spelling and agent address before you submit the $50 Certificate.

Mississippi LLC annual report: $0 by April 15

Mississippi LLCs must file an annual report online. Per the SOS, filings open on or after January 1 and are due by April 15. The domestic LLC annual report fee is $0 on the fee schedule (Form F0108).

Failure to file may lead to administrative dissolution. You will need your Mississippi Business ID. Save the confirmation even though there is no fee.

Example: after forming in 2026, treat April 15 as a recurring compliance date and confirm in the portal whether a report is due in the formation year for your entity.

Even with a $0 fee, missing the April 15 annual report can lead toward administrative dissolution. File early in the January–April window once the portal allows your entity.

Use the SOS annual-report menu after login and enter the Business ID carefully—wrong IDs are a common cause of filing confusion on busy April weeks.

After filing: get the business ready to operate

• Document how the LLC works. An operating agreement can set ownership, contributions, decision-making, distributions, and exit arrangements. Mississippi’s filing office generally does not require you to file the agreement with the formation paperwork—keep it with your company records. For multiple owners, resolve disagreements before money or contracts are committed.
• Get an EIN when needed. Form the entity first, then use the free IRS application if eligible. An EIN service fee pays someone to assist; it is not an IRS charge. Save the confirmation for banking and tax records.
• Separate business finances. Ask the bank for its document checklist and establish a bookkeeping process. Use the correct legal business name on applications and contracts; keep any trade-name registrations consistent.
• Check taxes and operating permissions. LLC formation does not itself select S-corporation taxation or issue a professional license. The IRS explains LLC tax classifications. Identify the state and local requirements for your actual work before opening.
• Check the current BOI rule. As of this review, FinCEN exempts entities created in the United States from beneficial-ownership reporting. A newly created domestic LLC generally falls within that exemption. Consult FinCEN directly before buying a BOI filing add-on.

For a simple one-owner operation, organize these tasks into a short checklist. Where ownership, investors, or tax elections are complicated, formation paperwork alone will not resolve those decisions.

After filing, confirm Mississippi Department of Revenue accounts separately from the SOS Certificate and annual report.

Match insurance to the work your LLC performs

Entity formation and insurance solve different problems. Ask the insurer to identify the correct business and operations; ask clients or landlords what coverage and certificate of insurance they require. Use the relevant guide to compare coverage:

• Mississippi cleaning business insurance
• Mississippi food truck insurance
• Mississippi HVAC insurance
• Mississippi landscaping insurance
• Mississippi daycare insurance

Mississippi LLC questions before you file

What is the cheapest way to form a Mississippi LLC?

The Certificate of Formation is $50 online with the SOS. ZenBusiness Starter advertises a $0 formation service fee plus the same $50 state fee. The annual report is $0 but must still be filed by April 15. Always separate state fees from any optional registered-agent or compliance add-ons you choose at checkout.

Is the Mississippi LLC annual report really free?

Yes—Form F0108 is listed at $0. It is due by April 15 and must be filed online.

Can I be my own Mississippi registered agent?

Yes, if you maintain a Mississippi street address and meet SOS rules.

Does forming an LLC give me a Mississippi business license?

No. Formation is with the SOS. Tax accounts and local licenses are separate.

Can I get an EIN without buying a service?

Yes. The IRS issues EINs free after the LLC is formed, if you are eligible.
