LLC Operating Agreement

An LLC operating agreement is the internal rulebook for your limited liability company. It defines ownership stakes, profit splits, management authority, and what happens when members join, leave, or disagree. Think of it as a contract between all LLC members that overrides the generic default rules your state would otherwise impose.

Operating agreements typically run 5 to 20 pages for a straightforward LLC, according to the U.S. Small Business Administration. Complex multi-member arrangements with custom profit-sharing, intellectual property provisions, or investor classes can stretch much longer. You do not file this document with any state agency. It stays with your internal business records.

No state requires you to file the operating agreement with the Secretary of State. But 5 states (California, Delaware, Maine, Missouri, and New York) legally require that you create one and keep it on file. In every other state, it is optional but strongly recommended. Without one, your LLC defaults to state statutory rules that may not match your actual intentions for profit-sharing, voting, or management.

If you formed your LLC in California, Delaware, Maine, Missouri, or New York, the answer is yes by law. In New York, you must adopt a written operating agreement within 90 days of filing your Articles of Organization under NY LLC Law § 417. New York law imposes no penalty for failing to create one, but your LLC will default to state statutory rules that rarely match what founders actually want.

Even if your state does not require it, you almost certainly need one for practical reasons. Banks routinely ask for a signed operating agreement before opening a business account. Lenders and investors will want to see proof of ownership and management authority. And if your LLC is ever sued, a court may question whether your LLC is truly separate from you personally if you have no formal agreement in place.

For single-member LLCs, an operating agreement reinforces the separation between you and the business. That separation is exactly what protects your personal assets. Skip the agreement, and you risk a court treating your LLC as a sole proprietorship in disguise, which means your personal bank account, home, and other assets could be on the table.

A solid operating agreement covers 8 core areas. The exact clauses depend on your LLC's complexity, but these are the provisions every LLC should address regardless of size or state.

• Ownership and capital contributions spell out each member's initial investment (cash, property, or services) and ownership percentage. This clause also sets the rules for future capital calls.
• Profit and loss distribution defines how income flows to members. Without it, most states default to equal splits, which can be unfair if one member invested significantly more.
• Management structure determines whether the LLC is member-managed (all owners run it) or manager-managed (a designated manager handles operations). It also defines who can sign contracts and bind the company.
• Voting rights set thresholds for decisions. Common setups require a simple majority for routine decisions and unanimous consent for major actions like selling the business or admitting new members.
• Transfer restrictions control whether members can sell their interest to outsiders, and often include a right of first refusal for existing members.
• Buy-sell and succession provisions address what happens when a member dies, divorces, retires, or wants out. Smart agreements specify a valuation method (appraisal, book value, or earnings multiple) and can be funded by life insurance policies.
• Dispute resolution requires mediation or arbitration before litigation, which can save $10,000 to $100,000+ in legal fees.
• Dissolution procedures outline the steps for winding down the LLC, paying debts, and distributing remaining assets to members.

You have three paths to creating your LLC operating agreement, and the right one depends on your budget and complexity.

Path 1: DIY with a free template ($0). Several state-affiliated websites and legal publishers offer free templates. This works well for single-member LLCs with straightforward operations. Fill in your LLC name, member info, ownership percentage, and management structure. The risk is missing state-specific nuances or important clauses like buy-sell provisions.

Path 2: Online legal service ($40 to $100). Platforms like LegalZoom ($99), Bizee, and ZenBusiness ask you questions about your business and generate a customized document. LegalZoom includes the operating agreement in their Pro package ($249 total, which also covers LLC formation and EIN filing). This is a good middle ground for most LLCs with 1 to 3 members.

Path 3: Hire an attorney ($200 to $1,000+). Custom-drafted agreements consider your specific state laws, profit-sharing arrangements, and member dynamics. The average review cost is about $520 based on marketplace data. For complex multi-member LLCs, especially those with outside investors or unique IP arrangements, attorney-drafted agreements are worth the investment. Business lawyers typically charge $150 to $400 per hour, with flat-fee arrangements running $500 to $1,500 for basic LLC formation plus operating agreement.

Once your operating agreement is complete, have all members sign it, date it, and keep copies with your business records. No notarization is required, though some members choose to notarize for added credibility.

The operating agreement itself has no state filing fee because you never file it with the government. Your total cost depends entirely on how you create it.

DIY templates cost $0. Free templates are available from sites like Northwest Registered Agent, LLC University, and some Secretary of State websites. You fill in the blanks. The downside is that generic templates may not cover state-specific provisions or complex member arrangements.

Online services charge $40 to $100. LegalZoom's standalone operating agreement starts at $99. Bizee's operating agreement add-on runs $40 to $100 depending on the package. These services ask you questions and generate a customized agreement. Good for single-member and simple multi-member LLCs.

Attorney-drafted agreements cost $200 to $1,000+. The average attorney review costs about $520 across all states. Flat-fee arrangements for a complete custom agreement typically range from $500 to $1,500. Complex agreements with multiple member classes, unique IP provisions, or investor protections can push past $2,000. The investment often pays for itself by preventing disputes that could cost $10,000 to $100,000+ in litigation.

For context, the operating agreement is just one part of your total LLC formation cost. State filing fees range from $35 to $500, and a registered agent typically costs $100 to $300 per year if you use a service.

Only 5 states legally require an operating agreement. The rest strongly recommend one but do not mandate it. Here is the breakdown for the most commonly searched states.

For state-by-state formation details and requirements, check your SBA.gov business structure page or your state's Secretary of State website. If you are operating in a state other than where you formed, read about foreign LLC registration requirements.

Mistake 1: Not having one at all. Even in states that do not require it, skipping the operating agreement means your LLC is governed by generic state rules. Those default rules often split profits equally regardless of investment and give every member equal management authority. If that is not your intention, you need an agreement.

Mistake 2: Using a generic template without customization. A template is a starting point, not a finished product. Templates from other states may include provisions that conflict with your state's LLC act, or they may miss critical clauses like buy-sell provisions, dispute resolution, or tax election details.

Mistake 3: Skipping the buy-sell clause. If a member dies, divorces, goes bankrupt, or simply wants out, and you have no buy-sell provision, you can end up in a legal nightmare. The operating agreement should specify a valuation method and payment terms for every exit scenario.

Mistake 4: Vague management and decision-making authority. If your agreement does not clearly define who can sign contracts, open bank accounts, or commit the LLC to major expenditures, any member (or manager) could legally bind the company. In Delaware, for example, state law defaults to giving every member and manager that authority.

Mistake 5: Never updating the agreement. Your operating agreement is not a set-it-and-forget-it document. When you add a new member, change ownership percentages, or elect S Corp tax treatment (via IRS Form 2553), you need to amend the agreement. Include a clear amendment procedure in the original document so updates do not require unanimous consent for routine changes.

Mistake 6: Forgetting the tax election clause. Your operating agreement should state how the LLC will be taxed (partnership, S Corp, or C Corp) and who serves as the partnership representative for IRS purposes. If you are considering the S Corp election for tax savings, read our LLC vs S Corp comparison first. And if you still need an EIN for your LLC, our EIN application guide walks you through the free process.
