A single-member LLC operating agreement is a short internal document that records who owns and runs the LLC, even when that is only you. No US state makes you file one, but banks, payment processors, and your own liability protection make it close to essential. This page explains what a sound agreement covers and how to get one prepared properly. It does not hand you a fill-in template, because a real operating agreement should match your actual company, not a generic form.
The agreement is what proves the company is separate from you and that you control it, which matters most when you run it from abroad.
You keep it with your records and show it to a bank when asked. Nothing goes to the Secretary of State.
It is a legal document. Keep a single-member agreement standard, and have anything unusual drafted or reviewed by a qualified professional.
When you form a one-person company, the operating agreement is the document everyone forgets until a bank asks for it. It is the internal rulebook of your LLC: who owns it, who runs it, and the fact that the company is a separate legal thing from you personally. For a non-resident founder running the company remotely, that last point is the whole reason it is worth getting right. This page explains when a solo owner needs one, what a sound agreement covers, why a one-person LLC is less informal than it looks, and how to get an agreement prepared without turning a legal document into guesswork. If you are still deciding on the structure itself, start with what an LLC is.
What a single-member LLC operating agreement is
An operating agreement is the contract between you and your LLC. It sets out the ownership, who manages the company, how money moves in and out, and the rule that the company's assets and debts are its own, not yours. In a multi-owner company this is where partners negotiate splits and voting. In a single-member LLC there is no one to negotiate with, so it reads more like a declaration: you own all of it, you run all of it, and you are keeping it separate from your personal affairs. For income tax the company is, by default, a disregarded entity reported on the owner's return, but tax treatment and governance are two different things. The operating agreement governs how the company is run regardless of how it is taxed.
Do you actually need one if you are the only owner?
No state requires you to file an operating agreement for a single-member LLC, and most do not require you to have one at all. So why bother? Three reasons carry real weight:
Banks and processors ask for it. Opening a US business bank account or a payment-processor account almost always means producing an operating agreement alongside your formation documents and EIN. Without it, the application stalls.
It backs up your liability shield. The protection of an LLC depends on treating the company as genuinely separate from yourself. An operating agreement that states that separation, and is then followed in practice, is one of several things a court looks at when deciding whether to respect the company as its own entity. It is not a guarantee on its own, but its absence is a gap.
It proves who controls the company. When you operate from another country, an agreement naming you as the sole member and manager is clean evidence of ownership and authority that a bank, a partner, or a successor can rely on.
Why a one-person LLC is not as informal as it looks
It is tempting to treat a solo LLC as a formality, especially when you own all of it and answer to no one. The US tax system does not see it that way, and this is the part non-resident founders most often miss. A single-member LLC is disregarded for income tax, but a single-member LLC owned by a non-US person is treated as a separate corporation for one specific reporting duty. Under section 6038A it must file a pro forma Form 1120 with a Form 5472 attached each year, a requirement the IRS spells out in the Form 5472 instructions. In other words, the IRS already regards your one-person company as a distinct entity with its own federal obligations. The operating agreement is the internal side of that same reality: the document that records the company as separate from you. Treating the LLC as a real, separate entity on paper and in practice is what the whole structure depends on, and the annual Form 5472 filing is the clearest reminder that it is one.
What a sound single-member operating agreement should cover
A workable single-member agreement is short, but it should still address each of the points below. These are the substance of the document, not legal wording to copy, and a properly prepared agreement puts them in the right form for your company and state:
Formation details the company's legal name, the state it was formed in, the date, and its registered agent and office.
The sole member and ownership that you own all of the company, that there are no other members, and that your ownership comes from the contribution you make to the LLC.
Capital contribution the money or property you put in at the start, with a value assigned to anything that is not cash. This initial contribution is what your ownership is built on, so the agreement records it and makes the buy-in clear.
Management that the company is member-managed and you have authority to act for it, including opening bank accounts and signing contracts.
Profits, distributions, and bookkeeping that the company's profits and distributions belong to you and that you can take a distribution as long as the company can still pay its debts, plus how it keeps its own financial records, tracks capital and distributions in separate accounts, and closes its books at year end.
Limited liability and separateness that the company is a separate legal entity and that you keep its money and records apart from your own. This is the part that backs up your liability protection, and mixing personal and company funds is one of the fastest ways to undermine it.
Tax treatment that the LLC is a disregarded entity for US federal income tax by default unless it elects otherwise, as set out in IRS Publication 3402.
Dissolution and succession how the company is wound up if you close it or can no longer run it. As a rule it settles its debts and liabilities first and distributes anything left to you, and the agreement can set out whether the company continues or ends on the owner's death or incapacity.
What an outsider would receive what a creditor or other claimant gets if they ever reach your membership interest, which is generally economic rights only rather than control of the company. For a single-member LLC this protection is limited and varies by state, one more reason to have the agreement prepared properly rather than copied from a generic form.
Amendment that you, as the sole member, can update the agreement in writing.
How to get one prepared
Putting these points into a signed agreement is not complicated, but it is still a legal document. A generic form copied from the internet can miss details that matter for your state or your situation. For a standard single-member LLC the substance is simple enough that many founders prepare and sign one without much trouble. If your setup is anything but standard, the safe move is to have the agreement drafted or reviewed by a qualified professional rather than leaning on a one-size-fits-all template. That covers cases like outside investment, unusual management arrangements, or more than one owner. CORPBOLT forms your LLC, but it is a formation service, not a law firm, so for the operating agreement itself the rule we point founders to is simple: keep it standard, or get professional help.
How to store and use it
Once you have a signed agreement, you generally do not need to notarize it or file it anywhere. You keep it with your company records and produce a copy when a bank or processor asks. Store it alongside the rest of the documents you receive after forming an LLC, and have your EIN ready at the same time, since banks usually ask for both together.
Single-member, multi-member, and state versions
A single-member agreement is built for one owner. If your LLC has two or more members, you need a multi-member operating agreement instead, which adds ownership percentages, how profits are split, and how decisions get made. That is a different document, not a tweak to a single-member one. A single-member agreement works in any US state, but if you formed in Wyoming there are a few state-specific points worth understanding alongside it, covered in the guide to a Wyoming LLC for non-residents.
Frequently asked questions
Does a single-member LLC need an operating agreement?
No state requires you to file one, and most do not require you to have one. In practice you need it anyway, because banks and payment processors ask for it and because it supports the liability protection that is the point of an LLC.
Do I have to file my operating agreement with the state?
No. The operating agreement is an internal document. You keep it with your company records and show it when a bank, processor, or partner asks; it never goes to the Secretary of State.
Can I write my own operating agreement?
You can, and for a standard single-member LLC the substance is simple. Because it is still a legal document, the safe approach is to keep it standard or, for anything unusual, have a professional draft or review it, rather than relying on a generic fill-in form that may not fit your state or situation.
Does it need to be notarized?
Generally no. Your signature as the sole member is usually enough to make it effective. Some banks have their own preferences, so check if a specific provider asks for notarization.
Why does my bank want my operating agreement?
Banks use it to confirm who owns and controls the company and who is authorized to open the account, especially when the owner is abroad. It is a standard part of the documents they review alongside your formation papers and EIN.
Does owning a single-member LLC mean I can be informal about it?
No. A foreign-owned single-member LLC is disregarded for income tax but is treated as a separate entity for the annual Form 5472 reporting it must file, so the IRS already regards it as distinct from you. Keeping an operating agreement and respecting the company as separate is part of treating it the way the law already does.
How this article was prepared
CORPBOLT prepared this guide for non-US founders forming a single-member LLC. The default disregarded-entity tax treatment is drawn from the IRS single-member LLC page and Publication 3402; the foreign-owned reporting point, that such an LLC files a pro forma Form 1120 with Form 5472, from the IRS Form 5472 instructions; and the "some states build it into statute" point from California Corporations Code section 17701.13 and New York LLC Law section 417, all linked below. We are careful not to overstate those statutes: neither requires you to file the agreement, and a missing one rarely invalidates an LLC. Operating agreements are governed by state law and individual facts, so this is general information, not legal advice. CORPBOLT is a formation service, not a law firm, and anything beyond a standard single-member agreement should be drafted or reviewed by a qualified professional. Last reviewed June 2026, against IRS guidance current to the Form 5472 instructions revised December 2024.
