When you form a single-member LLC, most states do not require you to file an operating agreement with anyone. It is an internal document, not a public one. That makes a lot of new LLC owners assume they can skip it entirely. That is a mistake.
Banks require it before they will open a business account. Some states require it by law. And if you are ever in a dispute or audit situation, it is one of the primary documents used to prove that your LLC is a legitimate, separately operating business. The good news: writing one is far simpler than most people think.
What an Operating Agreement Actually Is
An operating agreement is an internal document that establishes how your LLC is governed and operated. Think of it as the rulebook for your own company. It answers questions like: who owns this business, how are profits distributed, who makes decisions, and what happens if the business closes?
For a single-member LLC, those answers are simple: you own 100%, you make all decisions, all profits go to you, and if the business closes, you handle the wind-down. The document does not need to be long or complex. Most single-member LLC operating agreements fit on two to four pages.
Critically, an operating agreement is not filed with your state. You keep it with your business formation documents. When a bank or client asks for it, you provide a copy. Otherwise, it sits in your records as evidence of your intent to run a legitimate LLC.
Why Single-Member LLCs Still Need One
Banks Will Ask for It
When you go to open a business bank account, most banks will ask for your operating agreement as part of the account opening process. Mercury, Chase, and most credit unions list it as a required or commonly requested document. Having it ready lets you move through the process without delays.
Some States Require It by Law
California, New York, Missouri, Maine, and Delaware require LLCs to have an operating agreement on file. In these states, skipping it is not just a bad idea: it is technically non-compliant. Even in states where it is not legally required, many attorneys and CPAs recommend having one as baseline documentation of your LLC’s operating structure.
It Reinforces Your Legal Separation
Your LLC’s limited liability protection depends on you actually treating the LLC as a separate entity. An operating agreement is a written declaration of that intent. If you are ever sued and a plaintiff argues that your LLC is just a shell for your personal finances, your operating agreement is one of the first pieces of evidence your attorney will use to defend the separation.
What to Include in a Single-Member LLC Operating Agreement
You do not need to cover every edge case. For a single-member LLC, focus on these core sections:
- LLC name and state of formation: The legal name of your LLC and the state where it was registered
- Member information: Your full legal name and address as the sole member, with 100% ownership
- Business purpose: A brief description of what your business does (can be general: “to engage in any lawful business activity”)
- Registered agent: The name and address of your registered agent
- Management structure: For a single-member LLC, this is simply “member-managed,” meaning you make all decisions yourself
- Capital contributions: Any money or assets you contributed to start the LLC
- Profit and loss allocation: 100% to the sole member (you)
- Distributions: How and when you will take money out of the business
- Dissolution: What happens if you decide to close the LLC (standard language: member has sole authority to dissolve)
- Effective date and signature: Sign and date the document
What You Do NOT Need to Overcomplicate
Single-member LLC operating agreements do not require an attorney. You do not need to pay $500-1,500 in legal fees for a document that covers one person owning 100% of their own business. Free templates from reputable LLC formation services like Northwest Registered Agent cover everything a solo operator needs and are drafted by attorneys.
Skip these if you are a solo operator:
- Complex buy-sell provisions (only relevant when you have multiple members)
- Voting procedures and quorum rules (irrelevant when there is one member)
- Detailed dispute resolution clauses between members (same reason)
Keep it simple. A clean, complete two-page document is more useful than a 20-page legal tome that buries the important details in boilerplate.
Where to Keep Your Operating Agreement
Store your operating agreement with your other formation documents:
- Physical copy: Keep it in a folder with your Articles of Organization, EIN confirmation letter, and any state correspondence
- Digital copy: Save a signed PDF in a cloud folder (Google Drive, Dropbox) labeled “Business Formation Documents”
- Bank copy: When you open your business bank account, the bank may want a copy. Bring a printed copy or have the PDF ready to upload or email
Update your operating agreement if your business purpose changes significantly, or if you add any members down the road. A dated, signed document is what makes it legally useful.
