One of the most common myths about running a solo LLC is that an operating agreement is optional paperwork you can skip if it is just you. It is not required by law in most states — but skipping it is also one of the more common ways people accidentally undermine the exact liability protection they formed an LLC to get.
What an Operating Agreement Actually Does
An operating agreement is an internal document that sets out the rules for how your LLC will be run, including member rights, profit distribution, and decision-making procedures. It is not filed with the state — you prepare it before or after formation and keep it with your LLC records. While not always legally required, it is highly recommended specifically because it helps protect your liability shield and clarifies member rights, even when you are the only member.
Why It Matters Even With One Owner
Your personal assets are generally protected from LLC debts and liabilities — but that protection has real exceptions, and maintaining proper separation between personal and LLC finances is one of the conditions that keeps it intact. An operating agreement is part of demonstrating that separation: it is documented evidence that your LLC is run as a genuinely separate entity, not an extension of your personal finances treated informally. Several banks also require one to open a business account regardless of what state law technically requires, alongside your Certificate of Formation and EIN.
What to Include, Even as a Solo Owner
A basic operating agreement should cover how profits and losses are allocated, how decisions get made, what happens if you want to add a member or bring on a partner later, and what happens to the LLC if something happens to you. None of this is complicated to write for a single-member LLC, but each piece is part of the paper trail that supports your liability protection if it is ever questioned.
