LLC Operating Agreement: What to Include (2026 Guide)

Your Articles of Organization create the LLC; your operating agreement says how it runs. It is a private contract between the owners (members) that sets out ownership shares, management, profit distribution, voting and what happens when someone wants out. Most states do not make you file it, but banks ask for it, courts rely on it, and without one the state's default rules decide everything for you.

1. What an operating agreement is

An operating agreement is an internal document, signed by the members, that governs the LLC. It is not filed with the state (a few exceptions below) and it is not public. Think of it as the equivalent of corporate bylaws plus a shareholders' agreement, written for an LLC.

It matters because an LLC is a flexible entity: the law lets members organise ownership, management and profit-sharing almost any way they like — if they write it down. If they do not, the state's LLC act fills the gaps with default rules that may not match what the owners intended (for example, splitting profits equally even when one member invested far more).

2. Do you need one?

Yes, in practice, for every LLC — including a single-member LLC. Four reasons:

• Banks. Most US banks ask for the operating agreement when you open a business account, because it proves who is authorised to act for the company.
• Liability protection. The point of an LLC is that your personal assets are separate from the business. A signed operating agreement is one of the clearest signs that the LLC is a real, separately run entity — which helps if anyone ever tries to "pierce the veil" and reach your personal assets.
• Disputes. In a multi-member LLC, the agreement is what settles arguments over money, control, and exits. Without it, you are litigating over the state's default rules.
• Investors, lenders and buyers will ask for it in any due diligence.

3. States that require one

A few states legally require an LLC to have an operating agreement, even though it is still not filed publicly: California, Delaware, Maine, Missouri and New York (New York requires it to be adopted within 90 days of filing). In every other state it is optional under the law but expected by banks and advisers. Whatever your state, our Gold and Platinum packages include a customised operating agreement.

4. What to include: 10 essential clauses

1. Company basics — legal name, principal address, registered agent, purpose, and formation date.
2. Members and ownership — each member's name, capital contribution (cash, property or services) and percentage interest.
3. Management structure — member-managed (owners run it) or manager-managed (appointed managers run it). This also determines who can sign contracts.
4. Voting rights — one vote per member, or votes in proportion to ownership; which decisions need a majority and which need unanimous consent (selling the company, admitting members, taking on debt).
5. Profit and loss allocation — usually in proportion to ownership, but it can differ. Say when distributions are made and who decides.
6. Capital contributions — what each member has put in, whether more can be required, and what happens if a member cannot contribute.
7. Transfers of interest — whether a member can sell their share, rights of first refusal for other members, and what happens on death, divorce or bankruptcy.
8. Leaving the LLC — how a member withdraws, how their interest is valued, and how they are paid out (buy-sell terms).
9. Tax treatment — the LLC's tax classification (disregarded entity, partnership, S-Corp or C-Corp election) and who the tax matters partner is.
10. Dissolution — what triggers a wind-up, how assets are distributed, and the order of payments to creditors and members.

Also useful: a non-compete or confidentiality clause between members, a dispute-resolution clause (mediation before litigation), and rules for amending the agreement.

5. Single-member vs multi-member

Single-member LLC: your agreement is short — you are the sole member and manager, you own 100%, and you can amend it any time. It still needs to exist, be signed and be kept with your records: it is what your bank asks for and it supports the separation between you and the company. State what happens to the LLC if you die or become incapacitated (who takes over), which is the one clause a one-person company often forgets.

Multi-member LLC: the agreement is a real negotiation. Work through the hard questions before you sign — unequal contributions, one member working full-time while another is passive, what happens if someone stops contributing, and how you value a departing member's share. These are far cheaper to settle at the start than in a dispute. If members have different shares, say so exactly: Incofile's order form records each owner's percentage so the agreement matches.

6. Common mistakes

• Downloading a generic template and never adapting it (wrong state law, wrong management type, no buy-out terms).
• Never signing it, or signing and losing it. Keep a signed copy with your formation documents and your company records.
• Ownership percentages that do not match what members actually contributed.
• Not updating it when a member joins or leaves, or when you elect S-Corp status.
• Treating it as a formality and then ignoring it — for example, paying distributions that contradict what the agreement says.

7. How to get one

You have three options: draft one yourself from a template (fine for a simple single-member LLC, risky for partners), have a lawyer draft it (best for complex or high-value ventures), or use a formation service. Incofile's Gold and Platinum packages include a customised operating agreement prepared for your state, your members and your management structure, alongside your EIN and banking documents — so you have everything the bank asks for on day one.
