Single-Member LLC Operating Agreement: Template, Guide, and Why You Cannot Skip It

Banks Will Not Open Your Account Without It

Chase requires an operating agreement for every LLC business account application. Bank of America, Wells Fargo, US Bank, and PNC all have the same policy. Online-first banks like Mercury, Relay, and Novo also require one during digital onboarding. The bank needs to verify: (1) that you are the authorized signer, (2) the LLC's ownership structure, and (3) that no other party has authority over the account. Without a business bank account, you cannot maintain the personal-business financial separation that LLC protection depends on. In a 2023 survey by Fundera, 89% of small business owners who tried to open a business account without an operating agreement were turned away and had to return with one.

Liability Protection Depends on Formality

Single-member LLCs face a higher veil-piercing risk than multi-member LLCs. Courts scrutinize sole-owner entities more closely because the line between the owner and the business is thinner. In Curci Investments LLC v. Baldwin (2017), the California Court of Appeal emphasized that maintaining a written operating agreement, separate bank accounts, and formal records are the three primary factors courts consider when evaluating whether a single-member LLC is a legitimate separate entity. An operating agreement costs nothing and takes 20 minutes. Losing your liability protection can cost everything. The average veil-piercing judgment in state court between 2020 and 2024 was $347,000, according to data compiled by the American Bar Association.

S-Corp Election Requires It

If your single-member LLC earns more than approximately $40,000 in annual net profit, electing S-Corporation tax status can save significant self-employment taxes. Under S-Corp election, you pay yourself a "reasonable salary" (subject to FICA taxes of 15.3%) and take remaining profits as distributions (not subject to FICA). For a single-member LLC earning $120,000 net profit, paying a $60,000 salary and taking $60,000 as distribution saves approximately $9,180 per year in self-employment tax ($60,000 x 15.3%). The IRS requires an operating agreement as part of your corporate governance documentation when filing Form 2553 for S-Corp election. Without it, the election may be challenged.

State the LLC's legal name (exactly as filed with the state), state of formation, date of formation, principal office address, registered agent name and address, and business purpose. For the purpose clause, you have two options: a broad clause ("any lawful business activity permitted under [State] law") that gives maximum flexibility, or a narrow clause ("real estate investment and property management") that can limit liability exposure for activities outside the stated purpose. Most single-member LLCs use the broad clause.

Identify the sole member by full legal name and address. Document the initial capital contribution in specific dollar terms. If contributing property instead of cash, describe the property and its fair market value. State that the member holds 100% of the membership interest. Include a clause stating that no additional capital contributions are required, and that the member will maintain a capital account in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv).

Common initial contributions for single-member LLCs: freelancers and consultants typically contribute $100 to $1,000; e-commerce businesses contribute $2,000 to $10,000 for inventory; real estate LLCs contribute the property deed at appraised value; tech startups contribute $1,000 to $25,000 depending on initial development costs.

Confirm the sole member has exclusive authority over all business operations: signing contracts, opening and closing bank accounts, hiring and terminating employees and contractors, initiating and settling legal proceedings, purchasing and disposing of assets, and making all financial decisions. While this seems obvious for a single owner, putting it in writing is what banks and courts require. Also include a clause allowing the member to appoint agents or managers who can act on behalf of the LLC, with the member retaining ultimate authority. This is useful if you want a business partner, spouse, or employee to handle banking or sign contracts when you are unavailable.

State that 100% of net profits and net losses are allocated to the sole member. Define how and when distributions are made (monthly draws, quarterly distributions, or as-needed). Important: if you elect S-Corp tax status, the operating agreement must address "reasonable compensation" separately from distributions. The IRS specifically looks at operating agreements to determine whether an S-Corp's salary-to-distribution ratio is legitimate. Include your preferred accounting method (cash or accrual basis) and fiscal year (calendar year is standard for single-member LLCs taxed as disregarded entities). State that the member is responsible for all tax obligations arising from allocated income.

Name the bank where the LLC will maintain its accounts. Authorize the sole member as the primary signatory. State that the LLC will maintain separate books and records, including a general ledger, bank statements, tax returns, and copies of all contracts. This separation is the foundation of liability protection. Commingling personal and business funds is the single most common reason courts pierce the LLC veil. The LLC should have its own EIN (obtained free from the IRS), its own bank account, and pay its own expenses directly rather than having the member pay business expenses from a personal account.

This is the most overlooked section and arguably the most important. Specify what happens upon the member's death: does the interest transfer to a named heir, pass through the estate, or trigger dissolution? Name an emergency manager who can run the business during incapacity or estate proceedings. Without these provisions, a single-member LLC may automatically dissolve upon the member's death under many state statutes, leaving the business unable to operate during probate. Dissolution terms should cover voluntary dissolution (member's written decision), involuntary dissolution (court order, bankruptcy), and the winding-up process (pay creditors, distribute remaining assets). File Articles of Dissolution with your state after winding up.
