LLC Operating Agreement:
Why Single-Member LLCs Need One Too
An operating agreement is not just boilerplate. For a single-member LLC, it is the strongest piece of evidence that your LLC is a genuinely separate entity -- which courts look for before piercing the veil.
What Is an Operating Agreement?
An operating agreement is the LLC's internal rulebook. It documents who owns the LLC, how decisions are made, how profits are distributed, and what happens if a member wants to leave or dies. It is a private document -- you do not file it with the state in most cases.
Who it governs
Defines member ownership percentages, roles, and responsibilities. Even for a single-member LLC, it establishes who owns what and what decisions require formal approval.
How it protects
Establishes the LLC as a separate legal entity from its owner. Courts look for the operating agreement when deciding whether the LLC veil should be respected or pierced.
What it covers
Profit distribution, management structure, voting rights, transfer of membership interests, buyout terms, and dissolution procedures.
Is It Required?
Only 5 states require an operating agreement by law. Every other state leaves it optional. But "optional" does not mean "unnecessary."
For a single-member LLC, the operating agreement is the single most important document you can have for maintaining veil protection. Courts in piercing-the-veil cases consistently cite the absence of an operating agreement as evidence of alter ego treatment.
Core Sections of an Operating Agreement
Basic identifying information
LLC name, principal business address, state of formation, registered agent name, and stated business purpose.
Members and ownership
Legal names and addresses of all members, ownership percentage of each member, and initial capital contributions (what each member put in to start).
Management structure
Whether the LLC is member-managed (owner runs it directly) or manager-managed (a designated manager handles operations). Single-member LLCs are almost always member-managed.
Profit and loss allocation
How profits and losses are divided among members. Usually proportional to ownership percentage, but can be customised. Required for clarity and tax purposes.
Voting rights
What decisions require a vote, what percentage constitutes approval. For single-member LLCs, this is simple: the sole member makes all decisions.
Transfer restrictions
Rules about when and how membership interests can be transferred, sold, or gifted. Protects the LLC from unwanted new members.
Dissolution terms
What happens if the LLC is wound down, including how assets are distributed and how remaining obligations are handled.
