Single-Member LLC Operating AgreementTemplate, guide, and why you cannot skip it

27.1 million single-member LLCs operate in the United States. Every one of them needs an operating agreement, even though state statutes technically require it in only five jurisdictions. The text below explains why it matters and exactly what to include.

Why a Solo Owner Still Needs an Operating Agreement

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 have the same policy. Online-first banks (Mercury, Relay, Novo) require one during digital onboarding. The bank needs to verify (1) that you are the authorised signer, (2) the LLC's ownership structure, and (3) that no other party holds account authority. Without a business bank account, you cannot maintain the personal-business financial separation that LLC protection depends on. In a 2023 Fundera survey, 89% of small business owners who tried to open a business account without an operating agreement were turned away.

Liability Protection Depends on Formality

Single-member LLCs face a higher veil-piercing risk than multi-member LLCs. Courts scrutinise sole-owner entities more closely because the line between owner and business is thinner. In Curci Investments LLC v. Baldwin (Cal. Ct. App. 2017), the California Court of Appeal emphasised that 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 liability protection can cost everything. The average veil-piercing judgment in state court between 2020 and 2024 was $347,000, per ABA-compiled data.

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 tax. Under S-Corp election, you pay yourself a “reasonable salary” (subject to FICA at 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. The IRS reviews operating agreements when evaluating Form 2553 elections; without one, the election may be challenged. See Tax Provisions for the S-corp trap to avoid.

Section-by-Section: The Six Articles

A single-member operating agreement runs 4 to 5 pages. Each section below pairs the explanation with drafted sample language you may adapt.

Article I.

Organization & Formation

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.

Sample Clause LanguageThe Company, [Your LLC Name], LLC, was formed under the laws of the State of [State] by filing Articles of Organization with the [State] Secretary of State on [Date]. The principal office is located at [Address]. The Company is formed for the purpose of [purpose] and any other lawful activity permitted under [State] law.

Article II.

Member & Capital

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: freelancers contribute $100 to $1,000; e-commerce businesses $2,000 to $10,000 for inventory; real estate LLCs the property deed at appraised value; tech startups $1,000 to $25,000.

Sample Clause LanguageThe sole member is [Full Legal Name] residing at [Address]. The Member's initial capital contribution is $[Amount], paid by [cash / property]. The Member holds one hundred percent (100%) of the membership interests in the Company.

Article III.

Management

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 obvious for a single owner, putting it in writing is what banks and courts require. 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 when a spouse or employee handles banking or signs contracts.

Sample Clause LanguageThe Company is member-managed. The Sole Member possesses full and exclusive authority to manage the affairs of the Company, including without limitation the authority to execute contracts, open and close bank accounts, retain personnel, and dispose of Company assets.

Article IV.

Profit Allocation & Distributions

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 reviews operating agreements when assessing whether an S-Corp's salary-to-distribution ratio is legitimate. Include your accounting method (cash or accrual) and fiscal year (calendar year is standard for single-member LLCs taxed as disregarded entities).

Sample Clause LanguageAll profits and losses of the Company shall be allocated solely to the Sole Member. Distributions of available cash shall be made at the discretion of the Sole Member on a [monthly / quarterly] basis. The Company shall use the [cash / accrual] method of accounting and a [calendar / fiscal] year.

Article V.

Banking & Records

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 (free from the IRS), its own bank account, and pay its own expenses directly.

Sample Clause LanguageThe Company shall maintain its primary bank account at [Bank Name]. The Sole Member is the authorized signatory. The Company shall maintain books and records separate from those of the Member, including a general ledger, bank statements, tax filings, and contracts.

Article VI.

Succession & Dissolution

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, involuntary dissolution (court order, bankruptcy), and the winding-up process.

Sample Clause LanguageUpon the death or permanent incapacity of the Sole Member, the membership interest shall pass to [Named Successor] or, failing that, to the Member's estate. [Emergency Manager Name] is authorised to operate the Company during any period of incapacity until a successor is confirmed.

State-Specific Requirements

Five states explicitly require a single-member LLC operating agreement: New York (NY LLC Law § 417), California (Cal. Corp. Code § 17701.11), Delaware (Title 6, Ch. 18), Missouri (Mo. Rev. Stat. § 347.081), and Maine (Maine LLC Act § 1563). For details on each plus six other major states, see Requirements by State.

Five Common Drafting Errors

Omitting succession provisions
If you die without naming a successor or specifying that interest passes to your estate, the LLC may automatically dissolve. Your family then faces a frozen business, inaccessible bank accounts, and expensive probate.
Using a template from the wrong state
LLC laws vary significantly by state. A New York template may include provisions irrelevant to Texas, or miss requirements specific to your state. Always verify the template references your state's LLC statute.
Skipping the banking authorization clause
Without an explicit banking clause, you may face repeated requests from your bank for authorisation documentation every time you add a service, apply for a credit line, or add an authorized user.
Failing to sign and date the agreement
An unsigned operating agreement has no legal weight. Print it, sign it, date it, and retain the original with your company records. A digital signature with a timestamp (DocuSign, HelloSign, or similar) is valid in all 50 states under the ESIGN Act.
Not amending after major changes
If you change your LLC's name, move to a different state, add a member (converting to multi-member), or elect S-Corp status, amend the operating agreement to reflect the change. An outdated agreement creates inconsistencies that weaken liability protection.

When to Hire an Attorney

For most single-member LLCs, a template-based agreement reviewed against the chapters in this library is sufficient. Engage a licensed attorney when any of the following apply: the LLC will hold significant real estate (over $500,000); you intend to admit family members as additional members later; you are planning an S-corp election with disproportionate ownership; you operate in a regulated industry (medical, legal, financial services); or you are creating a multi-jurisdiction structure. Attorney drafting for a single-member LLC typically runs $500 to $800; a review pass on a template you have already drafted is $200 to $400.
