LLC Operating Agreement: What It Is, What It Covers, and Why You Need One
An LLC operating agreement is the foundational document that governs how your limited liability company is run: how decisions are made, how profits and losses are split, how members can exit, and what happens if the business is sold or dissolved. Even if your state does not require one, operating without an operating agreement is a mistake.

Why Every LLC Needs an Operating Agreement
An LLC operating agreement serves three critical functions: it establishes the rules that govern the business, it protects your limited liability by demonstrating that your LLC is a legitimate separate entity (not your personal alter ego), and it overrides the default rules in your state's LLC statute — rules that may not match what you and your co-members actually want.
Single-member LLCs too: Single-member LLCs benefit from an operating agreement even without co-members. It reinforces the separation between you and your business, which is essential for maintaining the liability shield. Some banks and business lenders require it before opening an account.
What an LLC Operating Agreement Must Cover
- Company name, purpose, and registered agent — basic formation details
- Member names and ownership percentages — who owns what share of the LLC
- Capital contributions — how much each member has contributed and what happens if more capital is needed
- Profit and loss distribution — how and when profits are distributed (usually pro rata to ownership, but not always)
- Voting rights and decision-making — what decisions require a simple majority vs. unanimous consent
- Management structure — member-managed (all members participate in decisions) vs. manager-managed (designated managers run day-to-day operations)
- Transfer of membership interests — can a member sell or transfer their interest? What are the right-of-first-refusal rules?
- Dissolution — what triggers dissolution and how assets are distributed
Member-Managed vs. Manager-Managed LLCs
- Member-managed — all members have authority to act on behalf of the LLC and participate in day-to-day decisions. Best for small LLCs where all owners are actively involved.
- Manager-managed — a designated manager (who may or may not be a member) runs the business. Other members are passive investors. Best for LLCs with investors who are not involved in operations.
Frequently Asked Questions
Is an LLC operating agreement required by law?
It depends on the state. California, Missouri, Maine, New York, and Delaware require LLCs to have an operating agreement. Most other states do not require one but strongly recommend it. Even where it is not required, operating without one means your LLC is governed entirely by your state's default LLC rules — which may not reflect what you and your co-members actually want.
Can a single-member LLC have an operating agreement?
Yes, and single-member LLCs should. An operating agreement for a single-member LLC reinforces the legal separation between you and your business, which is essential for maintaining the liability shield. Banks, investors, and some business contracts also require it.
What is the difference between an LLC operating agreement and articles of organization?
Articles of organization (sometimes called a certificate of formation) is the document you file with your state to legally create the LLC. It is a public document and covers basic formation details. The operating agreement is a private document between the members that governs the internal rules of the LLC. Both are important; they serve different purposes.
