Mississippi LLC Operating Agreement (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

No, Mississippi does not require an LLC to have an operating agreement, and you do not file one with the Secretary of State. Even so, a written operating agreement is strongly recommended for every Mississippi LLC: it sets ownership, management, and profit rules and can override the default provisions of the Mississippi Limited Liability Company Act (Title 79, Chapter 29 of the Mississippi Code).

Is a Mississippi Operating Agreement Required?

Mississippi does not legally require a limited liability company to adopt an operating agreement. You can form and run a Mississippi LLC without one, and the Secretary of State will never ask to see it. What the state does require to create the LLC is a Certificate of Formation filed with the Mississippi Secretary of State; the operating agreement is a separate, internal document that the company keeps in its own records.

Although it is optional, an operating agreement is one of the most important documents an LLC can have. The Mississippi Limited Liability Company Act, found at Title 79, Chapter 29 of the Mississippi Code, expressly allows members to enter into an operating agreement to govern the business, and it lets that agreement displace many of the statute's default rules. In other words, Mississippi gives you the freedom to write your own rules; if you do not, the state's defaults apply whether or not they fit your business. For the concept across states, see the national LLC operating agreement guide.

What an Operating Agreement Does

An operating agreement is the contract among the members (and, in a single-member LLC, the sole owner's own governing document) that defines how the company is owned and run. It answers questions that the Certificate of Formation does not: who owns what percentage, who has authority to make decisions, how money moves in and out, and what happens when circumstances change. Because it is a private contract, it can be tailored to the specific deal among the owners.

A well-drafted agreement does several practical jobs. It prevents disputes by writing down the members' understanding before problems arise. It reinforces the LLC's status as a separate legal entity, which supports the limited liability shield that protects owners' personal assets. And it satisfies third parties: banks, lenders, and investors frequently ask to review the operating agreement before opening accounts or providing financing. Without one, those routine steps can stall.

What to Include in the Agreement

While Mississippi does not dictate the contents, most operating agreements cover a standard set of topics. Consider including:

The agreement should also state the LLC's name, principal office, and registered agent, and how the agreement itself can be amended. Keeping these terms in one signed document gives every member a clear reference and reduces the chance of costly misunderstandings.

Member-Managed vs. Manager-Managed

One of the central decisions the operating agreement records is the management structure. Mississippi LLCs can be member-managed or manager-managed, and the choice affects who has authority to bind the company. In a member-managed LLC, the owners run the business directly and generally share the authority to act on the company's behalf. This is the most common structure for small, owner-operated businesses.

In a manager-managed LLC, the members appoint one or more managers (who may or may not be members) to handle day-to-day operations and decision-making, while the members take a more passive, investor-like role. This structure suits companies with silent investors or owners who prefer to delegate management. The operating agreement should clearly state which structure applies, name the managers if any, and describe the scope of their authority, because third parties and Mississippi's default rules will look to that designation to determine who can act for the LLC. This choice also appears on formation paperwork, so keep it consistent with your state filings.

Single-Member vs. Multi-Member Agreements

The value and content of an operating agreement differ somewhat between single-member and multi-member LLCs, but both benefit from having one. In a multi-member LLC, the agreement is essential because it governs the relationship among co-owners: how they split profits, how they vote, what happens if one wants out, and how disputes are resolved. Skipping the agreement in a multi-member LLC leaves these high-stakes questions to the statute's defaults, which rarely match what partners actually intend.

In a single-member LLC, there are no co-owners to negotiate with, but the agreement still matters. It documents that the business is a separate entity distinct from its owner, which helps preserve limited liability if a creditor or court ever challenges the LLC. It can also address succession, naming who takes over if the owner dies or becomes incapacitated. Because the federal government treats a single-member LLC as a disregarded entity by default, the agreement is one of the clearest pieces of evidence that the LLC is real and separate.

Mississippi's Statutory Default Rules

When an LLC has no operating agreement, or the agreement is silent on a point, the default provisions of the Mississippi Limited Liability Company Act fill the gap. These defaults address matters such as voting rights, allocation of profits and losses, members' authority, and the process for admitting members or dissolving the company. They are designed to provide workable rules for businesses that have not written their own, not to reflect any particular company's preferences.

That is precisely why an operating agreement is worth having. The statutory defaults may allocate profits differently than the members intended, allow transfers or decisions you would rather restrict, or set voting rules that do not match the owners' relative investments. By adopting a written agreement, the members override those defaults with terms they choose, within the limits the Act allows. Reviewing Title 79, Chapter 29 alongside your draft helps confirm which provisions you are keeping and which you are changing.

Adopting and Updating the Agreement

To put an operating agreement in place, the members prepare the document, agree on its terms, and sign it. There is no filing step: because Mississippi does not require the agreement and the state does not accept it, you simply keep the signed original with your company records and give each member a copy. Many LLCs adopt the agreement right after forming, once the Certificate of Formation is on file and the EIN is obtained.

An operating agreement is not a one-time document. As the business changes, ownership shifts, a member joins or leaves, or the management structure evolves, you should amend it to match reality, following the amendment procedure written into the agreement itself. Keeping it current ensures it remains a reliable reference and continues to support the LLC's separate legal status.

Frequently Asked Questions

Is an operating agreement required for a Mississippi LLC?

No. Mississippi law does not require an LLC to have an operating agreement, and you do not file one with the Secretary of State. However, a written agreement is strongly recommended for every Mississippi LLC to control how the business is run.

Do you file a Mississippi operating agreement with the state?

No. The operating agreement is an internal document kept in your company records. You file the Certificate of Formation with the Mississippi Secretary of State to create the LLC, but the operating agreement is never submitted to the state.

What should a Mississippi operating agreement include?

Typical provisions cover members and ownership percentages, capital contributions, how profits and losses are allocated, management structure, voting, admitting or removing members, transfer restrictions, and dissolution. It should also state whether the LLC is member-managed or manager-managed.

Does a single-member LLC in Mississippi need an operating agreement?

It is not required, but it is recommended. A single-member operating agreement documents that the LLC is a separate entity, which helps preserve limited liability, and it is often requested by banks when opening a business account.

What happens without an operating agreement in Mississippi?

The default rules in the Mississippi Limited Liability Company Act govern the LLC. Those provisions may not match your intentions on voting, profit sharing, or transfers, so relying on them means giving up control over key terms.

Member-managed or manager-managed: which should a Mississippi LLC choose?

Member-managed means the owners run the business directly and is common for small LLCs. Manager-managed places authority in one or more appointed managers, which suits passive investors. The operating agreement states which structure applies.
