What You Need Before Filing in Mississippi

- Registered agent with a physical street address in Mississippi. P.O. boxes are not accepted.
- Certificate of Formation details: LLC name, registered agent name and Mississippi address, management structure (member-managed or manager-managed), organizer name and address.

Step-by-Step: Forming a Mississippi LLC in 2026
Choose and Verify Your LLC Name
Search the Mississippi business entity database to confirm your name is available. Your name must include "Limited Liability Company," "LLC," or "L.L.C." and must be distinguishable from existing registered entities in Mississippi.
Appoint a Registered Agent
Every Mississippi LLC must designate a registered agent with a physical street address in Mississippi. The agent receives legal documents and state notices during business hours. Northwest Registered Agent charges $39 for Mississippi LLC formation and includes a free year of registered agent service (then $125/year).
File the Certificate of Formation
Submit your Certificate of Formation online or by mail to the Mississippi Secretary of State. The state filing fee is $50, non-refundable. Online filing processes in 1-3 business days.
Obtain Your EIN (Federal Tax ID)
Apply for an Employer Identification Number at no cost at IRS.gov. The application takes 5-15 minutes and the EIN is issued immediately online. An EIN is required for business banking, hiring employees, and filing taxes. Any formation service charging for EIN assistance is charging for a free government service.
Draft an Operating Agreement
An operating agreement is not legally required in Mississippi but is essential for any LLC with multiple members and strongly recommended for single-member LLCs. It defines ownership percentages, profit distribution, management authority, and dissolution procedures. Without one, Mississippi default rules apply. Northwest Registered Agent includes an operating agreement template with its formation package.
Meet Mississippi Ongoing Compliance
Every Mississippi LLC must file an Annual Report with the Secretary of State by April 15 each year (Miss. Code Ann. section 79-29-215). The fee for domestic LLCs is $0, but the filing is mandatory. Failure to file can result in administrative dissolution. File directly through the Mississippi Secretary of State online portal. Some owners receive unofficial solicitations - the state filing is free and should not be confused with third-party paid services.
