An LLC operating agreement is the internal rulebook for your company. It spells out who owns the LLC, how decisions get made, how profits are split, and what happens when a member leaves, dies, or wants out. It is a private contract between the members — you keep it with your records and do not file it with the state.
Here is the short answer: most states do not force you to have an operating agreement, but write one anyway. Banks routinely ask for it when you open a business account, it strengthens the liability shield separating you from your company, and without one your state’s default LLC statute — not you — decides how your company is run. This guide covers what goes into it, the clauses that matter, and how to get one without overpaying.

What Is an LLC Operating Agreement?
When you form an LLC, the state gives you two layers of documentation, and it helps to keep them straight:
- Articles of Organization (Certificate of Formation in a few states) — the short public filing that creates the LLC: name, address, registered agent.
- Operating agreement — the long private contract governing how the company works inside: ownership shares, money in and out, voting power, exit rules.
A corporation has bylaws and shareholder agreements; the operating agreement is the LLC equivalent, except far more flexible. Members can arrange ownership, management, and profit-sharing almost any way they like — even arrangements impossible in a corporation, such as giving one member 80% of the profits while another holds 60% of the voting power.
A few practical points:
- It is usually an internal document. With rare exceptions, you never send it to the Secretary of State. You store the signed original with your company records and produce copies when a bank, landlord, investor, or counterparty asks.
- It beats the default rules. Every state has an LLC statute that fills in the blanks when there is no agreement. Those defaults are generic — equal sharing, per-capita voting, automatic consequences on a member’s death — and rarely match what the founders intended.
- It can be amended. As the company grows, you change it via the amendment procedure written into the agreement itself.
Is an Operating Agreement Legally Required?
In most states, adopting an operating agreement is optional as a matter of law. Six states are commonly cited as requiring LLCs to have one — California, Delaware, Maine, Missouri, Nebraska, and New York. Even there, the agreement is something you adopt and keep, not something you file.
| State | Requirement (general summary) |
|---|---|
| New York | Members must adopt a written operating agreement; LLC Law §417 sets a deadline tied to filing the Articles of Organization. |
| California | The Revised Uniform LLC Act requires the LLC to have an operating agreement (written is strongly advisable). |
| Delaware | The LLC Act is built around the operating agreement as the governing contract; adopting one is treated as essential in practice. |
| Maine | Title 31 requires an operating agreement as part of the LLC’s foundational documents. |
| Missouri | State law requires a written operating agreement. |
| Nebraska | The Nebraska Uniform LLC Act is structured around the operating agreement as a required governing document. |
| All other states | Not legally required — but see the next section before you skip it. |
Laws change and details vary. Check your state’s current statute or ask a local attorney for a definitive answer.
Notice what even the “required” states do not do: none of them collect the agreement at formation. No office checks whether you wrote one. The requirement shows up later — when a bank, a court, or a departing partner asks you to prove how your company is owned and run.
Why You Need One Even If Your State Doesn’t Require It
If no one files it and no one checks, why bother? Because three audiences will ask for this document at exactly the moments when not having it is most expensive.
1. Your bank will ask
This is the most immediate reason. Nearly every bank — traditional and online-first alike — asks for an operating agreement when an LLC opens a business checking account. The reason is compliance: under federal Customer Due Diligence rules, banks must identify every “beneficial owner” (generally anyone holding 25% or more) and the person who controls the account. Your operating agreement is the cleanest proof of who those people are and who may sign for the company. Without one, expect delays, extra documentation requests, or a flat refusal until you produce it.
2. It protects your liability shield
The whole point of an LLC is separating your personal assets from business debts and lawsuits. That separation is respected when the LLC looks like a genuinely separate entity: separate bank accounts, separate books — and its own founding documents. A signed operating agreement is standard evidence the company is real and distinct from you. In a single-member LLC especially, where a court may look skeptically at the owner/company line, having the agreement (plus clean, un-mingled finances) is cheap insurance against a judge treating the LLC as your alter ego.
3. It overrides your state’s default rules
No agreement means the state statute decides. Typical defaults include splitting profits equally regardless of who invested what, one-member-one-vote regardless of ownership percentage, and harsh automatic outcomes if a member dies or divorces. If any of that differs from what you and your partners intend — and it almost always does — you need it in writing.
Single-Member vs Multi-Member Operating Agreements
Single-member LLCs need a shorter document, but they still need one. With no co-owners, the agreement’s job changes: it proves the LLC is a separate entity (helpful for banks and courts), names who inherits or winds down the company if you die or become incapacitated, and records basic rules on contributions and distributions. A few pages is infinitely better than nothing when a bank officer or judge asks.
Multi-member LLCs need the full treatment, because the agreement is where partners’ expectations get locked in while everyone is still friendly. Every clause below matters here — the exit provisions (buyout, transfer restrictions, valuation) most of all. Most partnership disasters come not from bad intentions, but from two people remembering a handshake differently three years later.
One more distinction: member-managed vs manager-managed. Member-managed means all owners run the business. Manager-managed means members appoint managers (owners or not) to run it, and everyone else is passive. Your agreement must state which you chose — banks look for it to know whose signature binds the company.
What to Include: The Clauses That Matter
A solid operating agreement covers these ten areas. Skipping any one leaves a gap that a default statute — or a future argument — will fill for you.
- Ownership percentages. Each member’s interest, stated precisely (e.g., 60/40). This is the number everything else builds on.
- Capital contributions. How much cash, property, or services each member put in (or commits to), how it was valued, and whether members can be required to contribute more later.
- Profit, loss, and distribution rules. How profits/losses are allocated (usually pro-rata, but it needn’t be), when distributions are paid, and who decides.
- Management structure. Member-managed or manager-managed; if manager-managed, who the managers are, how they’re appointed/removed, and their authority (spending limits, signing power).
- Voting rights and thresholds. What needs a simple majority vs a supermajority or unanimity (selling the company, admitting a member, major debt, amending the agreement), and whether voting is per-capita or by ownership share.
- Adding new members. The process and approval required, and whether new members vote immediately.
- Removing members and transfer restrictions. Whether a member can sell or give away their interest, a right of first refusal for existing members, and grounds for expulsion. Without this, a partner could sell their seat to a stranger.
- Buyout provisions. What happens when a member leaves, dies, becomes disabled, divorces, or goes bankrupt: is the interest bought back, by whom, at what valuation (formula, appraisal, book value), paid over what period?
- Dissolution. The events that trigger winding up, who handles it, and how remaining assets are distributed after debts.
- Tax elections and accounting. Default tax treatment (disregarded entity for single-member, partnership for multi-member), whether/how members may elect corporate or S-corp taxation, fiscal year, bookkeeping standards, and who serves as IRS partnership representative.
Worth adding for most companies: a banking and signatory clause (who can open accounts and sign), a dispute resolution method (mediation or arbitration before litigation), and an amendment procedure.
What Goes Wrong Without One: A Worked Example
Consider two founders, Alex and Sam, who launch a small e-commerce LLC as 60/40 partners — verbally. Alex contributes $20,000 in cash; Sam contributes sweat equity running operations. No operating agreement.
Problem one arrives at the bank. They apply for a business account. The bank’s beneficial-ownership check asks for the operating agreement to confirm the 60/40 split and who can sign. There isn’t one. Opening stalls while the founders draft under time pressure — the worst moment to negotiate ownership terms.
Problem two arrives with the first profits. The shop earns $50,000. Sam, who works full-time in the business, expects a salary-like draw. Alex expects distributions split 60/40. Both are “right” per their memory of a conversation two years ago — and their state’s defaults may split profits equally or by capital contribution, matching neither. An expensive dispute later, they settle for less than either would have accepted on day one.
Problem three arrives when Sam wants out. Sam is moving abroad and wants to sell. To whom? At what price? Can Sam sell to an outside buyer Alex has never met? Can Alex force a buyout, at what valuation? Nothing answers these questions, because nothing was written. A two-page buyout clause becomes a negotiation between lawyers instead.
Every one of these problems was preventable with a document that takes an afternoon to prepare. The agreement is cheapest on the day nobody needs it.
How to Get an Operating Agreement
You have three realistic routes. None involves filing anything with the state.
1. Hire a business attorney. Best for multi-member LLCs, unusual ownership splits, outside investors, or high-value property/IP contributions. An attorney drafts around your actual deal and flags state-specific issues a template can’t. It is also the priciest route — check current pricing locally, as fees vary widely. For a simple single-member LLC this may be more than you need; for partners mixing cash and sweat equity, it is money well spent.
2. Use a quality template and customize it. The budget route — but quality varies enormously. A generic template may say nothing useful about buyouts or tax distributions, and one written for another state’s law can quietly mislead you. Work through the ten clauses above, confirm each is addressed in your state’s terms, and if your structure is even slightly unusual, have an attorney review the draft.
3. Get one as part of your formation package. Many formation services include an operating agreement template (or a customized version) with formation. If you are forming anyway, this is the path of least resistance: one order files your Articles of Organization and produces the agreement. For example, Registered Agents Inc bundles business formation — state filing, a domain name, a website, and one year of free registered agent service — for $100 + state fee. Whatever provider you use, read the agreement before signing: “included” does not mean “customized to your deal.”
Whichever route you choose, finish properly: every member signs (electronic signatures are generally accepted), each member keeps a copy, and you store the master with your formation documents, EIN letter, and banking records.
Operating Agreements for Non-US Founders
If you are a non-US founder forming a US LLC, an operating agreement is just as available — and just as important — as for a US resident. Nothing about it requires US citizenship, a Social Security number, or a US address. A single-member agreement naming you as sole member is standard for foreign-owned LLCs.
Keep your signed agreement in the same folder as your approved Articles of Organization, EIN confirmation letter, and US bank records — US banks serving non-resident founders ask for exactly this bundle to verify ownership and signing authority. When you form your LLC with a service such as Registered Agents Inc ($100 + state fee), produce the agreement at the same time rather than months later, when a bank requests it; retro-drafting under deadline is how inconsistencies creep in.
Two cautions. First, the agreement does not change your tax obligations: a single-member LLC owned by a non-US person generally has annual IRS information-filing duties (Form 5472 with a pro-forma Form 1120) even when no US tax is owed. Second, if you later add a co-owner from another country, revisit the agreement with cross-border tax advice — multi-member foreign-owned LLCs are taxed as partnerships by default and the paperwork multiplies.
Keeping Your Operating Agreement Updated
An operating agreement is a living document. Review and formally amend it whenever the facts change:
- A member joins, leaves, or changes ownership percentage
- A significant new capital contribution
- The business pivots or starts operating in a new state
- You elect different tax treatment (e.g., S-corporation taxation)
- A member marries, divorces, or estate-plans their interest
Follow the amendment procedure in your agreement (typically a written amendment signed by the required majority), date it, and keep old versions. A tidy, current paper trail tells banks and buyers the company is well run — because it usually is.
FAQ
Is an operating agreement required for a single-member LLC?
In most states, no — but have one anyway. It proves your LLC is a separate entity (important for banks and your liability shield) and names who takes over or winds down the company if something happens to you.
Do I file the operating agreement with the state?
No. It is an internal document; even states that require one generally require you to keep it, not file it. You’ll show it to banks, landlords, partners, and counterparties instead.
Can I write my own operating agreement?
Yes. Many simple LLCs do. The risk is omission: missing buyout, transfer, or voting provisions only surface when there’s a dispute. A template customized clause-by-clause — or an attorney for complex cases — reduces that risk.
What happens if I never create an operating agreement?
Your state’s LLC statute supplies defaults on profit sharing, voting, and what happens when a member leaves or dies. Those defaults may not match your intentions at all — and you’ll still need a document the first time a bank asks for one.
How much does an operating agreement cost?
It depends on the route: attorney-drafted agreements cost the most (check current pricing with local firms), paid templates cost less, and some formation services include an agreement with formation. Compare that against the cost of a single partner dispute, which dwarfs all of these.
Can a non-US founder have an operating agreement?
Yes. There is no citizenship, SSN, or US-address requirement. Foreign-owned single-member LLCs routinely use a simple agreement, and US banks serving non-residents typically request it alongside your EIN letter and formation documents.
Conclusion
The operating agreement is the document your state mostly ignores and everyone else insists on. It settles ownership, money, and exit rules while relations are good, keeps bank account opening smooth, and helps your LLC look like the separate entity it is supposed to be. Whether your state requires one or not: write it, sign it, keep it current.
Still at the formation stage? Handle the operating agreement alongside your Articles of Organization. Form your LLC with Registered Agents Inc — $100 + state fee, including state filing, a domain name, a website, and one year of free registered agent service — then keep your signed agreement in the same records folder from day one.
