LLC Operating Agreement: What to Include
An LLC operating agreement is the internal contract adopted by an LLC's members to govern how the company is run. The Cornell Legal Information Institute describes it as a document that "can be used to regulate nearly all aspects of the LLC's affairs, including how the business is managed, how assets are used, and how revenues are shared." Most states do not require one, and it is not filed with the state - but it overrides the state's default LLC rules, which makes it a critical document for any LLC.

What an LLC Operating Agreement Is
An LLC operating agreement is the rulebook the owners of an LLC write for themselves. Cornell defines it precisely: "An operating agreement is the governing contract adopted by members of a Limited Liability Company (LLC)." The members set the terms, sign it, and are bound by it - Cornell notes that "once each member (owner) signs the document, it becomes a legally binding set of regulations that must be followed."
Its scope is broad. According to Cornell, the operating agreement "can be used to regulate nearly all aspects of the LLC's affairs, including how the business is managed, how assets are used, and how revenues are shared." Where the articles of organization create the LLC in the eyes of the state, the operating agreement governs the relationships inside it - among the members and between the members and the company. For the entity itself, see what is an LLC.
Cornell compares the operating agreement to the articles of incorporation a corporation adopts: both are foundational governing documents, but the operating agreement is built for the LLC's more flexible, contract-driven structure. That flexibility is the point - the members write the rules that fit their business rather than accepting a one-size-fits-all statutory template. It is the single document that most shapes how an LLC actually functions day to day.
Why It Matters (It Overrides Default State Rules)
The operating agreement matters because it lets members write their own rules instead of living with the state's. Cornell is explicit: "An operating agreement will override any default rules presented by a state LLC statute." Every state's LLC act contains default provisions - on voting, profit splits, and member exits - that apply automatically unless the members agree otherwise. The operating agreement is how the members agree otherwise.
The flip side is the risk of not having one. Cornell warns that "the absence of an operating agreement means that your business must be run according to the default rules of your state." Those defaults may not match what the owners actually intend - for example, a state might split profits equally by default even when members contributed unequal capital. That is why Cornell concludes that "although most states do not require the creation of an operating agreement, it is nonetheless regarded as a critical document." The U.S. Small Business Administration likewise lists an operating agreement as a recommended part of forming an LLC.
Is an Operating Agreement Required?
In most states, an operating agreement is not legally required, but a handful of states do mandate one, and every state treats it as important. Cornell notes that "most states do not require the creation of an operating agreement" - yet the document remains critical because it controls how the LLC operates and displaces the statutory defaults. Requiring versus recommending is a state-law question, so confirm your own state's rule.
Even where it is optional, an operating agreement is worth having for practical reasons: banks and investors often ask to see one, it prevents disputes among members by settling the rules in advance, and it reinforces that the LLC is a separate entity. This page is general information, not legal advice; whether and how to adopt an agreement depends on your facts and state, so consult a licensed professional for drafting.
It also helps to see where the agreement sits among an LLC's core documents. The articles of organization create the LLC with the state and are public; the operating agreement governs the LLC internally and is private; and the EIN from the IRS identifies it for federal tax. The SBA lists the operating agreement as a recommended part of forming an LLC precisely because the state filing alone leaves the internal rules unwritten. Adopting the agreement at formation - rather than after a dispute arises - is far easier, because the members are still aligned and no one is negotiating under pressure.
Key Provisions to Include
A thorough operating agreement addresses ownership, money, management, and change. Because it can "regulate nearly all aspects of the LLC's affairs," members can tailor each provision. The table lists the provisions most agreements cover and what each one settles.
| Provision | What it settles |
|---|---|
| Members & ownership % | Who the members are and each member's ownership interest |
| Capital contributions | What each member contributed and any future contribution duties |
| Profit & loss allocation | How revenues and losses are shared and when distributions occur |
| Management structure | Member-managed or manager-managed; managers' authority |
| Voting rights | Each member's voting power and what decisions need approval |
| Transfers & new members | How interests are sold or transferred and how members join |
| Withdrawal & buy-sell | What happens when a member leaves, dies, or is bought out |
| Dissolution | How the LLC winds up and distributes remaining assets |
Many agreements also record tax choices - for example, that a multi-member LLC is taxed as a partnership, with profits allocated to members and reported on Schedule K-1, or that the LLC will elect corporate or S corporation treatment. The agreement itself does not make the tax election - that is done on IRS forms such as Form 8832 or Form 2553 - but it can document the members' intent so the paperwork and the deal match.
How detailed to make each provision depends on the LLC. A two-owner service business may need little more than ownership percentages, a profit split, and a buy-out clause. An LLC with passive investors, unequal contributions, or plans to add members later usually needs fuller terms on voting thresholds, capital calls, and transfer restrictions. Because Cornell confirms the agreement can regulate "nearly all aspects of the LLC's affairs," the members control that level of detail - the cost of leaving a topic out is that the state's default rule fills the gap.
Single-Member vs. Multi-Member Agreements
Both single-member and multi-member LLCs benefit from an operating agreement, but the emphasis differs. A multi-member LLC needs one most: with two or more owners, the agreement is where they settle ownership percentages, profit splits, voting, deadlock-breaking, and exits before conflict arises. Under IRS default rules, a multi-member LLC is taxed as a partnership, so the agreement's allocation terms line up with how income is reported to each member.
A single-member LLC is not usually required to have one, but it is still worth drafting. For a single-member LLC - a disregarded entity for income tax by default - the agreement documents that the company is separate from its owner, states how it is managed, and supports the liability shield. Because courts can "pierce the corporate veil" when an owner treats the LLC as an alter ego, having and following an operating agreement is one more piece of evidence that the entity is run as genuinely separate.
Common Mistakes and How to Amend
The most common operating-agreement mistake is not having one at all - which, per Cornell, hands control of the LLC to the state's default statutory rules. Close behind are agreements that are signed once and then ignored: an agreement only helps if the members actually follow it, since Cornell notes it "becomes a legally binding set of regulations that must be followed" once signed. Other frequent errors include leaving profit-sharing or exit terms vague, failing to update the document when a member joins or leaves, and copying a generic template that conflicts with the members' real deal or with mandatory provisions of the state statute.
An operating agreement can be changed. Most agreements include an amendment clause stating the vote or written consent needed to modify the terms - for example, unanimous or majority approval of the members. When ownership changes, a capital contribution is added, or the management structure shifts, the members should amend the agreement in writing and keep the signed amendment with the original. Because the agreement is internal, amending it does not require a state filing; but if a change also affects the public articles of organization - such as switching from member-managed to manager-managed in a state that records that - you may need to update the state filing too.
It Is Not Filed With the State
Unlike the articles of organization, the operating agreement is a private, internal document. You do not file it with the state to form or maintain the LLC; the members simply adopt it, sign it, and keep it with the company's records. This is the key structural difference between the two core LLC documents: the articles of organization are public and state-filed, while the operating agreement is private and internal.
Keeping the signed agreement with your records still matters. Banks may request it to open a business account, new members will need to sign on, and it is the reference point if members ever disagree. Store it alongside your stamped articles, your EIN assignment notice, and your state filings.
Operating Agreement vs. Articles of Organization
These two documents are complementary, not interchangeable. The articles of organization are the public filing that creates the LLC with the state; the operating agreement is the private contract that runs it among the members. Cornell draws the analogy to corporations, noting the operating agreement plays a role for an LLC comparable to the governing documents a corporation uses. In short: file the articles to exist, adopt the operating agreement to govern. New owners typically do both around the same time - see how to form an LLC for the full sequence.

Frequently Asked Questions
What is an LLC operating agreement?
It is the governing contract adopted by an LLC's members. Cornell describes it as a document that can regulate nearly all aspects of the LLC's affairs - how it is managed, how assets are used, and how revenues are shared. Once members sign, it is binding.
Is an operating agreement required?
In most states, no. Cornell notes most states do not require one, but it is a critical document. Without it, the LLC runs on the state's default statutory rules, which may not match the members' intentions.
Do I file the operating agreement with the state?
No. It is an internal document kept by the members and is not filed. That contrasts with the public articles of organization, which you do file to create the LLC.
Does a single-member LLC need an operating agreement?
It is usually not required, but it is useful. A single-member agreement documents that the LLC is separate from its owner, records how it is managed, and helps support the liability shield.
What should an operating agreement include?
Common provisions cover ownership percentages, capital contributions, profit and loss sharing, management structure, voting, adding or removing members, and dissolution. Cornell notes it can govern nearly all aspects of the LLC's affairs.
Can an operating agreement override state law?
For default rules, yes. Cornell states an operating agreement will override any default rules presented by a state LLC statute. Mandatory statutory provisions still apply, and absent an agreement the state's defaults control.
