Start an LLC in Mississippi

When naming your Mississippi LLC, you’ll need to strike a balance between legal requirements and smart branding decisions. Per state law, your name must be unique from other registered businesses and include a proper designation like “LLC” or “Limited Liability Company.” You can search the Mississippi business database to check if your desired name is available before moving forward.

Beyond state laws, it’s important to think about the bigger picture—choose a name that clearly reflects your products or services, is easy to spell, and simple for customers to remember. It’s also a good idea to secure a matching domain name early, which can help you build a consistent and recognizable business identity.

Registering your domain name early is an important step in building and protecting your brand online. Securing your preferred web address as soon as possible reduces the risk of someone else claiming it, especially if your business name is unique or in demand. It’s also wise to purchase similar variations of your domain—such as common misspellings—and multiple extensions like .com, .net, or .co to prevent confusion and keep competitors from stealing traffic.

All LLCs in the state are required to appoint a Mississippi registered agent. A registered agent is an individual or a company (like Northwest) designated to receive legal and state mail on behalf of your business.

Your Mississippi registered agent must:

• Have a physical address in Mississippi (no P.O. Boxes)
• Be present at that address during regular business hours (9 AM to 5 PM)
• Agree to accept service of process on behalf of your LLC

Hire Northwest as your registered agent, and get more. You get access to a host of business services all geared toward creating and maintaining your business identity: online and off.

This is the final step before your LLC becomes active: submitting a Mississippi Certificate of Formation (LLC) and the associated fee to the Secretary of State. You can file the Certificate of Formation online for $54, or print it and mail it for $50 (but it will take longer to process).

Here’s what you’ll need to list on the form (remember, this information all becomes part of the public record once your Certificate of Formation is approved):

1. Company name
2. Business email
3. Effective date (optional)
4. NAICS code. To find your code, visit the NAICS association website.
5. Registered agent name and street address
6. Name and signature of the person filing your certificate

Your operating agreement is the road map to how your LLC will navigate major situations. This is where you’ll document important information such as how much each member invested, how voting will work, and even how you’ll dissolve the business if things go south.

Mississippi doesn’t technically require your LLC to have an operating agreement. But an operating agreement is a smart addition for any LLC: It helps provide guidelines for keeping your business operating correctly, and it helps maintain the LLC’s liability protection. And if you don’t have one, your business will be governed by Mississippi’s default LLC rules, thereby giving you less freedom to run your LLC as you see fit.

Your business’s Employer Identification Number (EIN) is the number the IRS will use to identify your business on tax forms. It’s similar to a Social Security Number, but for businesses instead of people.

EINs are required for all LLCs with multiple members or employees. However, even a single-member LLC with no employees will probably want an EIN, since it’s necessary for opening a business bank account (and can be used for any LLC matters that might otherwise require the owner’s personal SSN).

You can apply for an EIN for free directly from the IRS online, or let us get an EIN for you instead.

LLCs are required to file an annual report every year in Mississippi. The report provides the state with up-to-date contact information for your business, and lets it know if your LLC has changed ownership. The Mississippi Annual Report is free to file and due by April 15.

It’s crucial that your LLC has its own bank account. An LLC’s money has to be kept separate from the owners’ personal accounts in order for the LLC to maintain its limited liability status. If you mix business and personal funds, you risk being held personally liable for damages against the LLC.

When you go to open your business bank account, remember to bring the following:

• Mississippi LLC Certificate of Formation (a copy is fine)
• the LLC’s operating agreement
• the LLC’s EIN

If your LLC has more than one member, you may also need to provide an LLC resolution for banking account.
