It can be helpful for new business owners to have a checklist of tasks to ensure you are completing each step and that these are done in the right order. Typically, these requirements will include:

  1. Choosing a business name - Your business name will need to be unique and distinguishable from other active businesses in the state, as well as including a designator such as "LLC" or "Limited Liability Company".

  2. Appoint a registered agent - All LLCs formed in Mississippi are required to maintain an active registered agent with an updated physical address in the state to receive any service of process sent to your business.

  3. Submit your Certificate of Formation - This document will be what officially forms your LLC with the state and will include your business information, registered agent information, and ownership information.

  4. Draft an operating agreement - The operating agreement will be what details the roles and responsibilities of the business owners, as well as the processes for decision making and settling internal disputes.

  5. Obtain an EIN - An EIN will be issued to your business by the IRS and will act as a social security number for your business. This will be used for filing taxes, hiring employees, and setting up a business bank account.

  6. Maintain ongoing compliance - After formation, your LLC will be required to file annual reports each year and register for certain business licenses to maintain good standing.

This guide will aim to help new business owners understand the requirements for starting a new LLC in Mississippi, and provide tips for each step throughout the process. The order you do these in and how they are done can play a factor in your business's good standing. You can choose to either complete this process on your own or you can hire a service like Firstep to handle this for you. Regardless of what you choose, this guide will provide tips to set your business up correctly.

Step 1: Choosing a Business Name

The first step of starting a new Mississippi LLC will be to choose a business name. This name will need to be unique and distinguishable from the other active businesses in the state of Mississippi, and in Mississippi business names are held for a year after going inactive so it's important to check the state database to know if a name is available. Your business name will be what is registered with the state, and will be on all your formation and business documents. This name is important as it will be the first thing potential customers see when interacting with your business, and having a memorable name can help to attract more customers to become repeat customers. Also, if your chosen name relates to the products or services you offer this can be helpful for customers to remember you name easier and be more likely to become a lasting customer with steady sales.

If you have chosen a business name that is available but are not ready to form your LLC just yet, you can submit a name reservation for $25 to place the chosen name on hold until you are able to submit the Certificate of Formation. This is not required to do, for example if you have chosen an available name and ready to file, you can do this right away without the name reservation. A brainstorming session can be very useful for aspiring business owners because you can both get an idea of what is available in the state as well as get a few catchy names that you can potentially use for your LLC.

Step 2: Appoint a Registered Agent

All LLCs that are registered in Mississippi will be required to have a registered agent for their business. A registered agent will be responsible for receiving any service of process or important notices from the state that are sent to your business. This person can bed anyone you choose, but they must meet the requirements that are set by the state. These requirements will typically include:

  • Be at least 18 years old

  • Have a current and active physical address in the state of Mississippi (PO Boxes do not count)

  • Be available during regular business hours at your listed address (Monday-Friday 9am-5pm)

You can choose to be your own registered agent, appoint a trusted friend or family member, or you can hire a registered agent service to act in this role for your business. Hiring a registered agent service can be useful for many reasons, especially if you are a mobile business owner or you have multiple locations to be at each day. It's also important to be aware that your registered agent information will be listed on your Certificate of Formation, which is public information. This means your registered agent address will be on the state database, and if you act as your own registered agent your personal address will be listed. If you would like to avoid this then you can have a trusted friend or family member act in this role or hire a service instead. Keep in mind that if any of your registered agent information changes then you will need to update this change with the Secretary of State, and typically you will have around 30 days to do this to maintain your good standing.

Step 3: Submit Your Certificate of Formation

Now that you have chosen a business name that is available and you have a registered agent in place for your business, you are ready to file your Certificate of Formation to officially form your Mississippi LLC. You will be able to find this form by going to the Mississippi Secretary of State, clicking the business forms tab, and choosing to file a new LLC. This will require you to fill out certain information about your business, registered agent, and ownership. The Certificate of Formation will include:

  • Choose the business type, which in this case will be an LLC

  • Enter the business name including a designator such as "LLC" or "Limited Liability Company"

  • Enter the business email where the state can send important notifications to

  • Choose up to 3 NAICS codes which describe the business purposes

  • Next will be the registered agent information including the name, address, and email

  • Provide a signature to authorize the Certificate of Formation

  • Proceed to payment page to submit the $50 formation fee

Once you have submitted the payment for the Certificate of Formation you will want to download the document after it has been processed. The processing times for Certificate of Formation in Mississippi is instant, so you will be able to download your certified document right after submission. You can complete this process on your own or you can hire Firstep to do this for you to ensure your LLC is filled out correctly.

Step 4: Draft an Operating Agreement

Now that your LLC has been officially formed in Mississippi, a highly suggested next step will be to draft an operating agreement for your business. The operating agreement will detail the roles and responsibilities of the business owners, as well as the processes for how your LLC will conduct business. It will outline the ownership percentages, how the business will handle major decisions, how members join and leave the business, and strengthen the liability protection of the LLC.

Since the operating agreement is not filed with any government or state agency, this will mainly be used for internal purposes. Once you have gotten your operating agreement drafted it's important to save this to a safe place for when you need this document such as when you go to open a business bank account. In Mississippi, having an operating agreement is not required legally to have an active business.

It emphasizes the importance of having a written operating agreement and understanding the liability protection offered by the LLC structure.

Step 5: Obtain an EIN

After you have gotten an operating agreement, you will need to obtain an EIN for your business. This will be issued to your LLC by the IRS and will act as a social security number for your business. Your EIN will be used when filing taxes, hiring employees, or opening a business bank account. A nice thing about an EIN is that they will only be issued to each business one time, and they do not need to be renewed. So, once you get your EIN for your business you won't have to do anything else with it to keep it active or renew the number. However, if you do forget your EIN or lose the documentation for it you will need to retrieve your information from the IRS. This can be a lengthy process as the IRS does not have any set processing times and varies based on how busy they are. But, since you aren't able to register for a new number you must go through this process if you lose your EIN number. It's very important to save this to a safe place and ensure you don't misplace it to avoid having to go through this process, but it is still possible to handle this situation if it does happen.

You can choose to either obtain your EIN directly from the IRS or you can hire a service like Firstep to get this number for you during the process of forming the business. This way, when you are sent your Certificate of Formation you will also be sent your EIN, and if applicable your operating agreement as well, so your business is ready for operations right from the start.

If you do forget your EIN, Firstep can also retrieve this number for you as well. This can be helpful so you do not have to deal with any correspondence with the IRS as we will handle this step for you. Doing this allows you to continue to focus on your business operations while we handle the backend processes of the paperwork aspect of the LLC. Whether you choose to handle this process on your or hire a service, it's important to get this started before any important dates such as if you need to hire any employees or for tax season.

Step 6: Open a Business Bank Account

With your LLC officially formed and all the necessary documents acquired, it will be extremely helpful for your business to set up a business bank account. A dedicated business bank account will be used primarily to maintain a clear separation between your personal and business finances, which will help to continue the liability protections offered to LLC owners. These protections, sometimes referred to as the corporate veil, will protect your personal assets in case of any lawsuits or significant debts that are incurred by your business. If this were to happen, your personal assets will be protected and these debt collectors or courts will not be able to go after your personal assets such as your home, savings, or car.

One of the major aspects that goes into maintaining the liability protections for LLC owners is having a clear separation of personal and business finances. Having a dedicated business bank account will allow you to easily keep these separated, as well as ensure you have a clear way of knowing the available funds your business has. Especially as your business grows it can be difficult to track transactions and payments if you are using a personal account that has both personal and business finances. Avoiding this confusion and having an easy way to monitor the funds of your business, as well as ensuring your business does not engage in any illegal activities will allow you to maintain the liability protections for your assets.

Another benefit of a business bank account will be added credibility for your business when dealing with outside vendors or partners. This will allow you to send and receive payments by your actual business's name instead of your personal name, which can appear more professional and make these outside partners feel more comfortable when making payments out to your business instead of your personal business account.

Step 7: Maintain Ongoing Compliance

After your business has been formed and you have completed all the necessary tasks that go along with it, the most important thing you will need to continue to do is keep your business in good standing with the Secretary of State. This will include things such as submitting annual reports on time each year as well as registering for any required business licenses that are needed by businesses in your industry.

Annual Reports

All domestic LLCs in Mississippi will be required to file annual reports to renew their business registration each year. This form will update the business information, if needed, and will be due by April 15th each year. The total cost to submit this report is $0.

Business Licenses

Depending on the industry your business is in you may need to register for certain business licenses to be considered in good standing by the state of Mississippi. These vary based on what type of business you operate, what industry you are in, and the main products or services your business is selling. Be sure to research what relates to your specific situation after forming your business to maintain your good standing.
