What Is an Operating Agreement and Why Do You Need One?

An LLC operating agreement is the internal contract among the owners of a limited liability company that sets the rules for how the business is run, how profits and losses are divided, how decisions get made, and what happens when a member leaves, dies, or wants to sell. Every LLC should have one. Only a handful of states legally require it, but skipping the document doesn’t mean your business runs without rules. It means your state’s default LLC statute fills every gap, and those defaults rarely match what you and your co-owners actually intended. Once each member signs, the agreement becomes a binding contract governing the LLC’s internal affairs.1U.S. Small Business Administration. Basic Information About Operating Agreements

What the Document Does

Think of it as the LLC’s internal rulebook. It covers how the business operates day to day, how money flows between the company and its members, and how major changes like adding a partner or shutting down get handled. The agreement is private. You keep it with your company records rather than filing it with the state, which makes it different from the articles of organization you submit to form the LLC in the first place.1U.S. Small Business Administration. Basic Information About Operating Agreements

The agreement also reinforces the legal wall between you and your business. The whole point of an LLC is shielding your personal assets from business debts, but that protection isn’t automatic just because you filed formation paperwork. Without internal governance documents, your LLC can start to look like a sole proprietorship or general partnership to a court, which puts your personal liability protection at risk.1U.S. Small Business Administration. Basic Information About Operating Agreements

What Happens Without One

When an LLC has no operating agreement, every state has a set of default rules that automatically govern the company. These defaults are generic, and the consequences catch people off guard.

Equal Profit Splits Regardless of What You Put In

Under the default rules adopted by most states (many based on the Revised Uniform Limited Liability Company Act), each member receives an equal share of profits and losses regardless of how much money they contributed. If you put in $200,000 and your partner put in $50,000, the default rule in most states still gives you each 50% of the profits. An operating agreement lets you tie distributions to actual capital contributions or any other formula the members agree on.

Equal Votes and Unanimous Consent for Big Decisions

The default in most states is that every member gets an equal vote in managing the company, and routine business decisions pass by a simple majority. Anything outside the ordinary course of business typically requires unanimous consent. A single dissenting member can block a major decision, such as taking on debt or signing a large contract. An operating agreement lets you assign voting power in proportion to ownership, designate specific managers, or set custom approval thresholds for different categories of decisions.

Limited Control Over Who Gets In

Default statutes generally allow a member to transfer their economic interest in the LLC but not their management rights. The details vary, and without an operating agreement specifying transfer restrictions or approval requirements, you could end up with a stranger receiving profit distributions from your business while existing members have limited ability to prevent it.

Dissolution Triggered by a Single Departure

In many states, the default rule triggers dissolution when the LLC has no remaining members. If a single-member LLC owner dies without an operating agreement addressing succession, the LLC may dissolve rather than passing to an heir. Multi-member LLCs face similar risks if a member leaves and the remaining members don’t take the right steps within the statutory window.

When the Law Requires One

A handful of states, including New York, California, and Missouri, explicitly require LLCs to adopt an operating agreement. New York’s statute, for example, directs members to adopt a written operating agreement covering the company’s business, conduct of affairs, and members’ rights and responsibilities. Most other states don’t mandate one, but your LLC remains subject to default rules for anything the agreement doesn’t cover.

Even where no law compels you, banks and investors routinely ask to see an operating agreement before extending credit or funding. Without one, you may have difficulty opening a business bank account, securing a loan, or attracting outside capital. The document signals that your LLC operates as a real, structured business rather than an informal arrangement.

Protecting Your Limited Liability

Courts can “pierce the veil” of an LLC and hold members personally liable for business debts when the LLC and its owners look indistinguishable. Factors courts examine include whether the company followed basic formalities, kept separate finances, and maintained governing documents. Not having an operating agreement is one of the markers courts consider when deciding whether the LLC was truly treated as a separate entity. This applies especially to single-member LLCs, where the line between owner and business blurs easily.

An operating agreement alone won’t save you if you commingle funds or undercapitalize the business. But combined with a separate bank account, proper recordkeeping, and consistent adherence to the agreement’s terms, it creates a paper trail showing the LLC operates independently from you.

What Belongs Inside the Agreement

No two operating agreements look exactly alike, but certain provisions belong in virtually every one.1U.S. Small Business Administration. Basic Information About Operating Agreements

Ownership Percentages and Capital Contributions

State each member’s ownership percentage and how those percentages were determined, whether by cash investment, property contribution, or services. Address future capital calls too: what happens if the business needs more money, how members are notified, and how much time they have to contribute. If a member fails to meet a capital call and the agreement says nothing about consequences, the contributing members may have no clean way to adjust ownership. Their only remedy could be suing for breach of contract. Spelling out dilution or penalty provisions in advance avoids that fight entirely.

Management Structure

Specify whether the LLC is member-managed (all owners participate in running the business) or manager-managed (one or more designated managers handle operations). In a member-managed LLC, every owner has authority to bind the company in transactions. In a manager-managed LLC, day-to-day authority rests with appointed managers while other members act more like passive investors. This distinction affects who signs contracts, who hires employees, and who speaks for the company.

Voting Rights and Decision Thresholds

Set out how votes are allocated (per capita, by ownership percentage, or some hybrid) and what approval thresholds apply to different decisions. Many agreements use three tiers: a simple majority or manager discretion for routine operations, a supermajority of 66% or 75% for major decisions like taking on significant debt or entering a new line of business, and unanimous consent for fundamental changes such as admitting new members, amending the agreement, or dissolving the LLC.

Profit and Loss Allocation

Define how profits and losses are divided. This often mirrors ownership percentages, but it doesn’t have to. Some LLCs give certain members a preferred return before splitting remaining profits, or allocate losses differently from gains for tax planning. Whatever arrangement you choose, writing it down displaces the state’s default equal-split rule.

Distribution Schedule

Allocating profits on paper and actually sending cash to members are two different things. State when and how distributions happen, whether quarterly, annually, or at the managers’ discretion. Clarify whether the LLC can retain earnings for reinvestment and who makes that call.

Tax Classification and Tax Distributions

The IRS doesn’t recognize “LLC” as a tax classification. A single-member LLC is taxed as a sole proprietorship by default, and a multi-member LLC is taxed as a partnership. Either type can elect to be taxed as a corporation or an S corporation.2Internal Revenue Service. Entities 3 State which classification the LLC has elected, and require member approval before changing it.

Multi-member LLCs taxed as partnerships face a problem called phantom income. The LLC’s profits pass through to each member’s personal tax return whether or not the LLC actually distributed cash. A member could owe $30,000 in taxes on allocated income they never received. A tax distribution provision solves this by requiring the LLC to distribute enough cash each quarter for members to cover their estimated tax payments on allocated income. Without this clause, a majority of members could vote to reinvest all profits and leave minority members holding a tax bill with no cash to pay it.

Dispute Resolution

Include a mechanism for resolving disagreements before they reach a courtroom. A common approach requires mediation first, then binding arbitration if mediation fails. Skip this provision and any dispute goes straight to court, which is slower and more expensive for everyone.

Exit Strategies and Buyouts

The provisions people most often skip are the ones they most desperately need later. A buy-sell clause establishes what triggers a mandatory or optional buyout and how the departing member’s interest gets valued. Common triggers include death, disability, bankruptcy, and serious violation of the operating agreement. Death often creates an obligation for the remaining members or the LLC to purchase the deceased member’s interest, while other triggers create a right but not a requirement to buy. Without buy-sell terms, a deceased member’s interest passes to their estate, and the heirs become your new business partners whether you wanted them or not.

A right of first refusal gives existing members the option to match any third-party offer before a departing member can sell to an outsider. If the remaining members decline, the selling member proceeds with the outside buyer. This keeps unwanted outsiders out of the LLC while still letting members exit when they choose.

Buyout disputes almost always come down to price. Specify how a departing member’s interest will be valued: book value, fair market value set by an independent appraiser, a formula based on revenue multiples, or some other method the members agree on in advance. Picking the method now, while everyone is getting along, prevents an expensive valuation battle later.

If You’re the Only Owner

If you’re the sole owner, you might wonder why you need a contract with yourself. The reasons are practical. A written operating agreement for a single-member LLC helps maintain the legal separation between you and the business, which is the foundation of your liability protection.1U.S. Small Business Administration. Basic Information About Operating Agreements It also addresses scenarios the state’s default rules handle poorly for solo owners, like what happens to the LLC if you die or become incapacitated. Without an operating agreement directing otherwise, many states dissolve the LLC when it has no members. A simple provision naming a successor or authorizing your estate to continue the business can prevent that outcome.

Single-member agreements also matter when dealing with banks, landlords, and potential investors. These third parties want to see documentation proving the LLC has formal governance. The agreement doesn’t need to be long, but it should cover management authority, succession, distribution policies, and your chosen tax classification.

Writing, Signing, and Changing It Later

Operating agreements are internal documents. You don’t file them with any state agency, and most states won’t even accept them if you try.1U.S. Small Business Administration. Basic Information About Operating Agreements Keep the signed original with your company records alongside your articles of organization, meeting minutes, and financial statements.

Put It in Writing

Many states technically allow oral operating agreements, but relying on one is a mistake. Oral agreements are extremely difficult to prove in court, and they’re a steady source of litigation when members disagree about what was actually agreed to. New York explicitly requires operating agreements to be in writing. Even where oral agreements are enforceable, a written document eliminates ambiguity and gives every member something concrete to reference.

Templates vs. Custom Drafting

Online templates are inexpensive and fine for very simple, single-member LLCs with straightforward operations. For multi-member LLCs or any business with meaningful assets, custom drafting by an attorney is worth the cost. Professional drafting fees for a custom operating agreement typically range from roughly $500 to several thousand dollars depending on the LLC’s complexity, number of members, and the provisions required. That cost is modest compared to a single dispute that reaches litigation because the agreement was vague or incomplete.

Amendment Procedure

Your business will change. New members join, old ones leave, revenue grows, and priorities shift. Include an amendment procedure: who needs to approve changes, whether amendments must be in writing, and what vote threshold applies. A common approach requires written consent from all members. If the agreement is silent on how to amend it, most state default rules require unanimous consent, which means a single holdout can block any change no matter how sensible.

Fiduciary Duties

Members and managers of an LLC owe each other fiduciary duties of care and loyalty. Some states, notably Delaware and Nevada, allow operating agreements to significantly limit or even eliminate these duties by contract. Other states restrict how far members can go in waiving the duty of loyalty. If your LLC operates in a state that permits fiduciary duty modifications, the operating agreement is where those modifications must appear. This is an area where professional legal help earns its fee, because getting it wrong can either leave members overexposed or produce an agreement that isn’t enforceable.
