LLC operating agreement

An LLC operating agreement is the contract among the members of a Limited Liability Company (LLC) that sets how the company is run. It covers ownership, management, money, and exit. It binds the members, the managers, and anyone who later takes a membership interest. It is not the filing that creates the company. That is the articles of organization, filed with the state. It is also not a corporation's bylaws.

Some states call it a "limited liability company agreement" or an "LLC agreement." Delaware defines the term as any agreement "whether referred to as a limited liability company agreement, operating agreement or otherwise" among the members about the company's affairs [1]. All three names mean the same instrument.

Purpose and common uses of LLC operating agreement

The operating agreement replaces the state's default rules with the members' own. Delaware states a policy of giving "maximum effect to the principle of freedom of contract" to these agreements [1]. Where the agreement is silent, the statute fills the gap.

Common uses:

• Setting each member's ownership share and capital contribution.
• Choosing who manages: all members (member-managed) or appointed managers (manager-managed).
• Deciding how profits and losses are allocated and when distributions are paid.
• Setting voting rules and which decisions need unanimous consent.
• Controlling what happens when a member wants out, dies, or sells.

It matters for a single-member LLC as well. For federal income tax, the Internal Revenue Service (IRS) treats a one-member LLC as an entity disregarded as separate from its owner. A domestic LLC with two or more members is classified as a partnership by default [2]. The agreement should record the tax treatment the members intend.

Parties involved in LLC operating agreement

The parties are the members. A manager who is not a member may also be bound.

• Members own the company. They sign, contribute capital, and vote.
• Managers run day-to-day affairs in a manager-managed LLC. The agreement defines their authority and limits.
• Assignees and new members take on the agreement when they join or receive an interest. In Delaware, a member, manager, or assignee is bound "whether or not" they execute the agreement [1].
• The LLC itself is usually named in the agreement and acts under it.

Delaware also allows the agreement to be "written, oral or implied" [1]. New York goes the other way. Its members "shall adopt a written operating agreement" [3]. The rule depends on the state of formation.

Key terms and clauses in LLC operating agreement

Read these clauses first. The right wording depends on the state and the deal, so have a lawyer check anything material.

Clause	What it settles
Members and interests	Who owns what percentage
Capital contributions	What each member put in, and whether more can be called
Management	Member-managed or manager-managed, and decision thresholds
Allocations and distributions	How profit, loss, and cash are split
Transfers and exits	Consent rules, buyout triggers, valuation method
Duties	Standards of conduct owed by members and managers
Amendments	Who must approve a change
Dissolution	Events that end the company

Duties deserve a second look. Delaware lets the agreement expand, restrict, or eliminate fiduciary duties. It may not eliminate the implied covenant of good faith and fair dealing [1]. New York lets the agreement limit manager liability, but not for bad faith, intentional misconduct, knowing violations of law, improper personal benefit, or improper distributions [3].

Amendments are also state-specific. In New York, a change needs the written consent of each member adversely affected, unless the agreement provides otherwise [3].

Important dates and lifecycle events

An operating agreement has no fixed expiry date. It lives as long as the company does, so track events, not a term.

• Formation. New York allows the agreement to be entered into before, at, or within ninety days after filing the articles of organization. It cannot take effect before the company is formed [3].
• Tax election. An entity classification election on IRS Form 8832 cannot take effect more than 75 days before filing or more than 12 months after [2].
• Admission or exit of a member. Each one should trigger an amendment and an updated ownership schedule.
• Dissolution. In Delaware, an LLC dissolves at the time the agreement specifies. If none is set, it has perpetual existence. It also dissolves on events the agreement names, on a vote of members holding more than two-thirds of profit interests, when no members remain, or on a judicial decree [4].
• Last member leaves. In Delaware, the company can continue if the last member's personal representative agrees within 90 days, or another period set by the agreement [4].

Reporting duties also shift over time. Since FinCEN's final rule took effect on 14 August 2026, U.S.-formed companies are exempt from Beneficial Ownership Information (BOI) reporting to the Financial Crimes Enforcement Network (FinCEN) [5]. Check this again before relying on it.

Risks and common mistakes

• No signed agreement. The state default rules then govern. They may not match what the members expected.
• A generic template left unedited. Clauses about management, voting, or buyouts may contradict how the business actually runs.
• A stale agreement. The ownership table still shows a member who left two years ago.
• Unclear exit terms. Without a buyout method, a dispute over valuation starts from zero.
• Tax mismatch. The agreement describes partnership treatment while the company filed an election for something else.
• Assuming one state's rules apply everywhere. Delaware allows oral agreements. New York requires a written one [1] [3].
• Signed copy lost. Members cannot prove which version is in force.

Related contract types

The operating agreement sits beside other documents. Each has a different job.

• Partnership agreement. The equivalent for a general partnership. See what is a partnership agreement.
• Buy-sell agreement. A separate contract, or a section of the operating agreement, that sets the terms for buying out an owner.
• Consulting or services agreements. Contracts between the LLC and outside people who do work for it. See what is a consulting agreement.
• Member loan and guaranty agreements. Contracts between the LLC and an owner or lender about money.

Contract-management checklist

Run this against the real agreement, not a template.

1. Store the signed copy and every amendment in one place. Label the version in force.
2. Capture the state of formation, the members, their percentages, and the management model as structured fields.
3. Record the amendment rule and the transfer-consent rule so they can be found without rereading the document.
4. Diarise the formation window for signing, any tax election deadline, and any date the agreement itself names.
5. Set a reminder to review the agreement whenever a member joins, leaves, or transfers an interest.
6. Review ownership and capital schedules against the books once a year.
7. Re-check regulatory duties, such as BOI reporting, before each annual filing cycle.
8. Link related documents to the agreement: loans, guaranties, buy-sell terms, and key service contracts.
