Step 2: Fill Out the Certificate of Formation

In this step, we will help you complete the Mississippi Certificate of Formation form.


You will need to know the following information to complete the form:

  1. Entity Name
  2. Nature of Business and Effective Date
  3. Registered Agent Name and Registered Office Address

Entity Name

Having a creative and smart business name is important but not as important as having a legally correct name.


When you choose a name for your business, you have to make sure the name:

  • meets Mississippi naming guidelines. 
  • is not already in use by another business in Mississippi. 


Follow the Mississippi Naming Guidelines:

  • Your name must include the phrase “limited liability company” or one of its abbreviations (LLC or L.L.C.).
  • Your name may contain the name of a member or manager of the LLC.
  • Your name cannot contain the following words: bank, banker, bankers, banking, trust company, insurance, trust, corporation, incorporated, partnership, limited partnership, or any abbreviations or words of similar meaning.
  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
  • Your name must be distinguishable from any existing business in the state. This includes Mississippi reserved names.


Check Name Availability:

Is your name available in Mississippi? Make sure the name you want isn't already taken by doing a name search on the Mississippi Secretary of State website.

Register Your Domain Name:

We recommend checking to see if your business name is available as a web domain. Even if you don't plan to make a business website today, you may want to buy the URL to prevent others from acquiring it.

Nature of Business and Effective Date

If your business will have a different effective date than the date of filing, indicate the date. This cannot exceed 90 days of filing.

Indicate the nature of your business using up to three NAICS codes. You can search for the appropriate codes using the US Census Bureau’s website.

Registered Agent and Registered Office

A registered agent accepts and sends legal documents on your LLC’s behalf. When you register your Mississippi LLC, you are required to list your registered agent and your registered office. 

Your registered agent can be anyone 18 years or older that lives in Mississippi. Your registered agent must always be available at the registered office during regular business hours.

Steps After Your Mississippi LLC Is Officially Formed

Once you’ve filed your Certificate of Formation, you should take the following steps:

Create an Operating Agreement

An LLC operating agreement is a legal document that outlines the ownership structure and member roles of your LLC.

In Mississippi, you aren’t required to have an Operating Agreement to officially form an LLC, but it's still a good idea to have one. You can start your operating agreement before, during, or after you file your Certificate of Formation.

Your operating agreement will be kept in your LLC’s private business records; you do not file it with the state.

For more information, read our Mississippi LLC Operating Agreement guide.

Get an EIN

An Employer Identification Number (EIN) is like a social security number for your LLC. You will need an EIN if you want to hire employees or open business bank accounts.

You can get your EIN for free through the IRS website, via fax, or by mail. If you would like to learn more about EINs and how they can benefit your LLC, read our What is an EIN article.

Open a Business Bank Account

Using dedicated business banking and credit accounts is essential to protect your business' corporate veil. When your personal and business accounts are mixed, your personal assets (your home, car, and other valuables) are at risk in the event your LLC is sued.

Get Licenses and Permits

When you are registering an LLC, you need to determine if your business needs any licenses or permits in order to remain compliant. On the federal level, there are a handful of business activities that require licenses and/or permits.
