A business operating agreement is a private written contract among the owners of a Limited Liability Company — called members — that sets out how the company is managed, how money moves in and out, how ownership can change hands, and what happens when members disagree or leave. It is an internal document, never filed with the state, and it governs the LLC alongside whatever the state’s LLC statute says. Most states don’t require one, but without it your business runs on generic default rules that rarely match what the owners actually intended.
It is the single most important internal document an LLC can have. Everything from who can sign a contract to who gets paid first out of profits lives in this one agreement.
What a Business Operating Agreement Covers
A well-drafted agreement addresses a predictable set of topics. Skip any one of them and your state’s default statute fills the gap for you.
Who Runs the Company
Every LLC has to decide whether it is member-managed or manager-managed. Under the model law most states follow, an LLC is treated as member-managed unless both the articles of organization and the operating agreement specifically say otherwise.
In a member-managed LLC, every owner shares in running the business. Each member can negotiate deals, sign leases, and take on debt in the company’s name. Ordinary decisions typically pass by a simple majority of the members, while actions outside the normal course of business, such as selling major assets, generally require unanimous consent. This structure fits small businesses where all owners are actively involved.
In a manager-managed LLC, one or more designated managers handle daily operations while the other members act as passive investors. Managers may be members themselves or outside professionals. This setup suits LLCs with silent investors or members who want to contribute capital without running the business. The agreement should spell out which decisions the manager can make alone and which require member approval.
Ownership Stakes and Voting Rights
The agreement records each member’s ownership percentage, which usually reflects their share of capital contributions. That percentage drives two things: how profits and losses are divided, and how much weight each member carries in company decisions.
Voting rights usually track ownership percentages — pro-rata voting — so a member who owns 60% has more say than one who owns 40%. Some agreements use a per-capita system instead, where every member gets one vote regardless of investment. Either approach is valid, but the choice should be deliberate and written down. The agreement should also set vote thresholds for different kinds of decisions:
- Simple majority for routine operational decisions like approving budgets or entering ordinary contracts.
- Supermajority, typically two-thirds or three-quarters, for significant actions like taking on substantial debt or admitting new members.
- Unanimous consent for fundamental changes such as amending the operating agreement, dissolving the company, or merging with another entity.
Capital Contributions and Capital Calls
The agreement documents the initial capital each member puts into the business. Contributions don’t have to be cash — they can include real estate, equipment, intellectual property, or professional services. The agreed value of non-cash contributions should be recorded so every member’s equity stake is clear from day one. Those values establish each member’s capital account, which tracks what the business owes them over time.
Many agreements also include capital call provisions that let the company request additional money from members later. The agreement should say who can trigger a capital call, how much notice members receive, and what happens if a member can’t or won’t contribute. Common consequences include dilution of the non-contributing member’s ownership percentage or, in more aggressive agreements, forfeiture of part of their interest. Without these provisions, an LLC may have no practical way to raise money from existing members when it needs to.
Distributions and Taxes
The agreement controls how and when the company distributes profits. Distributions typically happen on a quarterly or annual schedule, though members can set any timeline they want. Profits and losses are usually allocated by ownership percentage, but the agreement can override that — for instance, giving a managing member a larger share for their hands-on role.
LLCs taxed as partnerships don’t pay federal income tax themselves. The business files an informational return and each member receives a Schedule K-1 showing their share of income, deductions, and credits. One frequently overlooked provision is a tax distribution clause, sometimes called a phantom income provision. Because members owe tax on their share of profits whether or not cash was actually paid out to them, a well-drafted agreement requires the LLC to distribute at least enough cash each year for members to cover the resulting tax bills. Without this clause, a member can get hit with a tax liability on profits the company kept for reinvestment.
Members of an LLC taxed as a partnership generally owe self-employment tax on their share of business earnings if those earnings exceed $400. The self-employment tax rate is 15.3%, applied to 92.35% of net self-employment income.1Internal Revenue Service. Topic No. 554, Self-Employment Tax
An LLC’s tax treatment isn’t fixed at formation. By default, a single-member LLC is taxed as a disregarded entity and a multi-member LLC as a partnership, but any LLC can elect to be taxed as a C corporation or an S corporation by filing Form 8832 with the IRS.2Internal Revenue Service.

Buy-Sell Provisions
Buy-sell clauses control what happens when a member wants to leave, retires, dies, or divorces. They typically require a departing member to offer their interest to the remaining members before selling to an outsider, giving the existing owners a right of first refusal. This prevents a stranger from joining the business without the other members’ consent.
The agreement should also establish a valuation method so there is no fight later over what the departing member’s interest is worth. Common approaches include using the company’s book value, applying a multiple of recent earnings, or commissioning an independent appraisal. Some agreements set a fixed formula that updates annually; others call for a third-party valuation at the time of the triggering event. Without a predetermined method, buyouts can turn into drawn-out disputes.
Fiduciary Duties and Dispute Resolution
Members and managers owe fiduciary duties to one another and to the company — primarily a duty of loyalty (don’t compete with or steal from the business) and a duty of care (make reasonably informed decisions). In many states, LLC operating agreements can modify or even eliminate specific fiduciary duties. The one thing that can never be waived is the implied covenant of good faith and fair dealing. If you are a passive investor, you want strong fiduciary protections written in. If you are a manager who runs other businesses, you may need carve-outs for outside activity.
The agreement should also set a path for resolving disputes before anyone files a lawsuit. Many agreements require mediation first, then binding arbitration or litigation if mediation fails. Specify the timeline for each step, who bears the costs, and where any arbitration or lawsuit will take place. Setting this up in advance is dramatically cheaper than figuring it out in the middle of a heated dispute.
Liability Protection
The main appeal of an LLC is the liability shield between the business and its owners’ personal assets. That shield isn’t automatic. Courts can pierce the veil and hold members personally liable if the LLC is treated as the owner’s alter ego — commingling personal and business funds, undercapitalizing the business, or failing to maintain the LLC as a separate entity. Having a written operating agreement and actually following it is one of the strongest defenses against a veil-piercing claim, because it shows the business operates independently from its owners.
The agreement can also protect against outside creditors of individual members. In most states, a personal creditor of a member can only obtain a charging order, which redirects any distributions the debtor-member would have received but gives the creditor no voting rights or management authority. Clauses that let the remaining members buy out a member who becomes subject to a charging order, or expel one who files personal bankruptcy, keep outside creditors from getting a foothold in the company.
Why a Single-Member LLC Still Needs One
If you are the only owner, signing an agreement with yourself can feel pointless. It isn’t. A written operating agreement for a single-member LLC shows courts you treat the business as a separate entity, which matters for keeping your liability shield intact. Without one, a judge may conclude the LLC is simply your alter ego and hold you personally responsible for business debts.
It also handles what happens if you die or become incapacitated. Without succession language, a memberless LLC can dissolve under state default rules if the owner’s estate doesn’t act within a short statutory window. The agreement can name a successor member who automatically steps in, or grant the estate full membership rights, including management authority, on your death.
Operating Agreement vs. Articles of Organization
These two documents are often confused and do completely different work. The articles of organization — sometimes called a certificate of formation — are a public filing with the state that officially creates the LLC. They contain basic information like the company’s name, its registered agent, and the county or address of its principal office. Filing fees range from about $35 to $500 depending on the state. Once approved, the LLC legally exists.
The operating agreement is a private internal document that is never filed with any government agency. The articles tell the state the company exists; the operating agreement tells the members how the company actually works. Keeping it internal also keeps your ownership splits, distribution arrangements, and governance rules confidential from competitors and the public.
Amendments differ too. Changing the articles usually means filing an amendment with the state and paying another fee. Amending the operating agreement is an internal process governed by the agreement’s own terms. If the agreement doesn’t say how to amend itself, most states default to requiring unanimous member consent for any change, which is one more reason to include an amendment procedure from the start.
What Happens Without One
A handful of states legally require every LLC to adopt an operating agreement, and some of those accept oral or implied agreements while others demand a written one. In the rest, it is strongly recommended but not required. Either way, operating without one means your business is governed entirely by your state’s default rules. Those defaults rarely match what the members would have chosen.
Typical defaults include:
- Equal profit sharing — all members split profits and losses equally, regardless of what each one actually invested.
- Unanimous consent for major decisions — every member must agree before the company can act outside its ordinary business, which can paralyze operations if even one member objects.
- Member-managed by default — every member is treated as an agent with authority to bind the company to contracts, even members who were meant to be passive investors.
A customized agreement replaces those one-size-fits-all rules with ones that fit the actual business. You can give a larger profit share to the member who contributed more capital, set a majority threshold for ordinary decisions, or designate a single manager to run operations. Any provision you don’t address in writing falls back to whatever your state statute says.
What It Costs to Put in Place
Cost depends on the complexity of the LLC and how you draft the agreement. Online legal services and formation platforms offer template-based agreements for roughly $40 to $200. Templates work for simple single-member or two-member LLCs with straightforward structures.
For multi-member LLCs with significant capital, complex distributions, or unusual governance, hiring an attorney is the safer route. Attorney-drafted agreements typically run $500 to $1,500, and highly customized agreements for larger businesses can go higher. The investment pays for itself if it prevents a single dispute, since member litigation can easily cost tens of thousands of dollars. The operating agreement itself carries no filing fee because it is internal, but you still pay your state’s filing fee for the articles of organization that create the LLC in the first place.
