When you form an LLC, the state receives a short filing with your company's name, registered agent, and a few other basics. What the state doesn't get is the rulebook: who owns what, who makes decisions, how money comes out, and what happens if someone leaves or dies. That's the job of the operating agreement.
If you're the only owner, it's tempting to skip it. Here's why you shouldn't, and what a solid operating agreement covers.
What is an LLC operating agreement?
An operating agreement is the internal governing document of an LLC. It's a contract among the members, and with the LLC itself, that sets out ownership, management, finances, and the rules for major events. Some states call it a limited liability company agreement.
It usually isn't filed with the state. You sign it, keep it with your company records, and update it when things change.
Is an operating agreement required?
It depends on the state. A handful of states require LLCs to have one, while most don't. But "not required" doesn't mean "not needed."
Without an operating agreement, your state's LLC law supplies default rules for how the company is managed, how profits are shared, and what happens when a member leaves. Those defaults are written for the general case, not your business, and they may not match what you intended. Check your state's requirements in our LLC state guides.
Why a single-member LLC needs an operating agreement
It supports your liability protection
An LLC protects your personal assets only if it's treated as truly separate from you. Courts look at whether owners respected that separation when deciding whether to "pierce the veil" and hold them personally liable. A signed operating agreement is part of the record showing you set the business up as a distinct entity with its own rules. It won't save you if you mix personal and business money, but it helps show you ran a real company.
Banks and others may ask for it
Many banks ask to see the operating agreement when you open a business account, to confirm who owns the LLC and who can sign for it. Lenders, landlords, and larger clients sometimes ask too. Our guide to opening a business bank account covers what else to bring.
It plans for the unexpected
What happens to your LLC if you die or become incapacitated? Without a plan, state law and the probate process fill in the answers, which can leave your family unable to access business accounts or keep things running. An operating agreement can spell out who may step in to manage the business and how your interest passes.
It makes growth easier
If you add a partner or investor later, you'll have a framework to amend instead of starting from scratch in the middle of a negotiation.
What to include in an LLC operating agreement
Every agreement should fit the business, but most cover these sections.
Company basics
- The LLC's legal name and principal address
- The state and date of formation
- The registered agent
- The business purpose, often written broadly, such as "any lawful purpose"
- The duration, which is usually perpetual
Members and ownership
- Each member's name
- Capital contributions: what each member put in, such as cash, equipment, or services, and its agreed value
- Ownership percentages or units
- Whether members can be asked to contribute more money later, and what happens if someone doesn't
Management
- Whether the LLC is member-managed, where the owners run it day to day, or manager-managed, where designated managers run it and may or may not be members
- Who can sign contracts, open accounts, borrow money, and hire
- Which decisions need a majority vote and which need unanimous consent, such as selling the business, admitting new members, or taking on major debt
- Officer titles, if you use them
If your state asks for the management structure on your formation documents, make sure the agreement matches.
Profits, losses, and distributions
- How profits and losses are allocated among members
- When distributions are made, and who decides
- Whether the LLC will make tax distributions to help members cover taxes on their share of profits
- How the LLC is taxed, and who is responsible for tax filings
Transfers and exits
This is the section multi-member LLCs most often regret skipping.
- Restrictions on selling or transferring membership interests
- A right of first refusal for the company or the other members
- Buy-sell terms for death, disability, divorce, retirement, or a member who simply wants out
- How a departing member's interest is valued and paid for
- How new members are admitted
Dissolution
- What events trigger dissolution
- How debts are settled and remaining assets distributed when the business winds down
Housekeeping
- Records and bookkeeping
- Meetings and voting procedures, if any
- Indemnification of members and managers
- Dispute resolution, such as mediation or arbitration
- How the agreement itself can be amended
Single-member vs. multi-member operating agreements
| Section | Single-member focus | Multi-member focus |
|---|---|---|
| Ownership | Confirms you own 100% | Percentages or units, and each member's contributions |
| Management | Your authority to act for the LLC | Voting rules and who decides what |
| Distributions | Usually simple | Allocations, timing, and tax distributions |
| Exits and transfers | What happens on death or incapacity | Buy-sell terms, valuation, right of first refusal |
| Disputes | Rarely needed | Mediation, arbitration, and how to break a deadlock |
If your LLC elects S-Corp taxation
An S-Corp can have only one class of stock, which means every owner's rights to distributions and liquidation proceeds have to be proportional to ownership. If your LLC elects to be taxed as an S-Corp, the operating agreement should reflect that. Provisions common in partnership-style agreements, such as special allocations or preferred returns, can put the election at risk.
If you're considering the election, have a tax professional review your agreement. Our guide on when to elect S-Corp status covers the bigger decision.
Template, service, or attorney?
- A template can work for a simple single-member LLC, as long as you read it carefully and adjust it to your situation and your state.
- A formation service can prepare a standard agreement alongside your filing. EZ Entity Setup offers an operating agreement as a $125 add-on, and it's included in the Advanced plan; see our pricing page for details. EZ is not a law firm, so for custom terms or legal advice, an attorney is the right call.
- An attorney is worth the cost for multi-member LLCs, uneven ownership, outside investors, or complicated buyout terms.
Keep it signed, stored, and current
Sign the agreement when the LLC is formed or soon after, and make sure every member signs. Store it with your formation documents and EIN confirmation, where you can find it when a bank or lender asks.
Revisit it whenever:
- A member joins or leaves
- Ownership percentages change
- You change how the LLC is managed or taxed
- You bring in investors or take on significant debt
Follow the amendment process the agreement itself sets out, which usually means a written amendment signed by the members.
Bottom line
An operating agreement is your LLC's internal rulebook. Most states don't require one, but every LLC benefits from having one, including single-member LLCs, because it supports your liability protection, satisfies banks, and plans for what happens if you can't run the business.
Cover the essentials (ownership, management, money, exits, and dissolution) and keep it updated as your business changes. For multi-member LLCs or anything complex, have an attorney draft or review it.
