How to write an LLC operating agreement

An operating agreement is your LLC's internal rulebook. What to put in one, why even a single-member non-resident LLC needs it, and how to write it yourself.

An operating agreement is the internal rulebook for your LLC — who owns it, who runs it, how money moves, and what happens if things change. Most states don’t legally require one, but you want it anyway, even if you’re the only owner sitting in another country.

You can write one yourself. Here’s what goes in it and why it matters more than people think.

What an operating agreement actually is

It’s a contract between the members of an LLC that governs how the company works internally. Your Articles of Organization are the public filing that creates the company with the state. The operating agreement is the private document that runs it.

— Key takeaways
  • An operating agreement is your LLC's internal rulebook — private, not filed with the state.
  • Even a single-member non-resident LLC should have one; banks and Stripe ask for it.
  • It's the document that proves your LLC is separate from you, protecting your liability shield.
  • You can write a standard one yourself — no lawyer and no notary required.

Nobody files it. It lives with your company records, and you hand a copy to whoever asks — usually a bank or payment processor during onboarding.

Why a single-member non-resident LLC needs one

This is the part founders skip, and it’s a mistake. If you’re the sole owner, it feels pointless to write an agreement with yourself. It isn’t.

Three groups ask for it. Banks and fintechs — Mercury, Wise, Brex — frequently request the operating agreement during account opening to confirm who controls the company. Payment processors like Stripe and PayPal ask for it when they review a flagged account. And courts look at it when someone tries to argue your LLC is just you wearing a costume.

That last one is the real reason. The whole point of an LLC is the liability shield — the wall between your business and your personal assets. If you ever get sued and the other side can show there was no separation between you and the company, they can “pierce the veil” and come after you personally. A signed operating agreement is concrete evidence that the LLC is a real, separate entity with its own rules. For a single-member LLC, it’s one of the few documents you have that proves this.

It also overrides your state's default rules

Every state has a default LLC statute that fills in the gaps when you don’t have an agreement. Those defaults may not match what you want — on profit splits, on what happens if a member dies, on how the company dissolves. Writing your own agreement means your rules win, not the state’s generic ones.

The clauses that matter

A good operating agreement is shorter than people expect. These are the sections that earn their place.

  1. Members and ownership percentages

    List every member and the percentage each one owns. For a single-member LLC, that’s you at 100%. For a multi-member LLC, the percentages must add up to 100 and usually track who contributed what.

  2. Capital contributions

    Record what each member put in to start the company — cash, equipment, or services — and the dollar value. This sets the baseline for ownership and for what each member is owed if the company winds down.

  3. Management structure

    State whether the LLC is member-managed (the owners run it) or manager-managed (you appoint a manager). Most small LLCs are member-managed. Spell out who can sign contracts, open accounts, and bind the company.

  4. Profit distribution

    Explain how and when profits get paid out to members. It’s often pro-rata by ownership percentage, but you can structure it differently if everyone agrees. Note that distributions and tax allocations can differ.

  5. Voting rights

    Define who votes on what and how much each vote counts. Voting power usually follows ownership percentage. Decide which decisions need a simple majority and which need unanimous consent — like admitting a new member or selling the company.

  6. Transfer and buyout

    Set the rules for when a member wants to leave, sell their stake, or dies. A buy-sell clause says who can buy the departing member’s share, how it’s valued, and on what timeline. This prevents a co-owner from selling to a stranger you never agreed to.

  7. Dissolution

    Lay out how the company is wound up — what triggers it, how remaining assets and debts are settled, and the order members get paid back. Boring until you need it, and then it’s the most important clause in the document.

Single-member vs multi-member

The structure is the same; the stakes are different.

Single-memberMulti-member
Main purposeProve separation from you personallyGovern the relationship between owners
Ownership sectionJust you, 100%All members, percentages summing to 100
Voting clauseSimple — you decideCritical — defines who controls what
Buyout clauseOptional but usefulEssential — covers exits and disputes
Federal tax defaultDisregarded entityPartnership

For a single-member LLC, the agreement is mostly a formality that protects your liability shield and satisfies banks. Keep it simple. For a multi-member LLC, the agreement is the thing that stops a falling-out between owners from becoming a lawsuit. Spend more time on the voting, transfer, and buyout clauses, because those are what you’ll actually fight about later.

The split between the two structures has tax and control implications worth understanding before you write the agreement — we cover them in single-member vs multi-member LLC.

Do you need a lawyer or a notary?

Usually no, on both counts.

A standard agreement — single-member, or a simple multi-member with a clean ownership split — is a fill-in-the-blanks document. The clauses above are well-trodden. You write it, every member signs it, and it takes effect. There’s no notary, no witness requirement, and nothing to file with the state.

You’d bring in a lawyer for the genuinely unusual cases: outside investors with preferred terms, equity that vests over time, complicated profit waterfalls, or any deal where members are putting in wildly different amounts and want bespoke protections. If that’s not you, a clean template plus the right details is enough.

Match it to your real setup

The most common error isn’t a missing clause — it’s an agreement that doesn’t match reality. If your operating agreement says two members own 50/50 but your bank and EIN paperwork say single-member, you’ve created a contradiction someone will eventually flag. Keep the agreement, your EIN application, and your formation documents telling the same story.

When we form your LLC, the operating agreement comes with it — drafted to match your ownership, your state, and your EIN filing, so every document lines up before a bank or Stripe ever asks.

— Frequently asked
Does a single-member LLC need an operating agreement?
Legally, most states don't require one — but you still want it. Banks, Stripe, and PayPal often ask for it, and it's the document that proves your LLC is separate from you personally, which is what protects your liability shield.
Do I need a lawyer to write an operating agreement?
Usually no. A standard single-member or simple multi-member agreement is a fill-in-the-blanks document. You only really need a lawyer for unusual ownership splits, investor terms, or complex vesting and buyout arrangements.
Does an operating agreement need to be notarized?
No. An operating agreement is an internal contract between the members. It takes effect when the members sign it. No notary, no witness, and no filing with the state is required.
Do I file my operating agreement with the state?
No. Unlike your Articles of Organization, the operating agreement is private and stays with your records. You give copies to your bank or payment processor when they ask, but you never submit it to the Secretary of State.
