Does a single-member Ohio LLC need an operating agreement?

It is not required, but strongly advised. A single-member operating agreement documents that the LLC is separate from its owner, which helps preserve limited liability, and it is often requested by banks when opening a business account.

What happens if my Ohio LLC has no operating agreement?

The default rules in Ohio Revised Code Chapter 1706 govern the LLC. These cover management, voting, profit sharing, and transfers, but they may not match what the members intended, which can cause disputes an agreement would have prevented.

Q: Is an operating agreement required for an Ohio LLC?

No. Ohio does not legally require an LLC to have an operating agreement, and you do not file one with the state. However, Ohio Revised Code Chapter 1706 fully recognizes operating agreements, and one is strongly recommended to override the statutory defaults.

Q: Do I file my Ohio operating agreement with the state?

No. The operating agreement is an internal document kept with your company records. Ohio does not accept or file it. You file only the Articles of Organization (Form 610) with the Ohio Secretary of State to create the LLC.

Q: Member-managed or manager-managed in Ohio?

By default an Ohio LLC is member-managed, meaning members run the business. You can instead choose manager-managed, where designated managers handle operations. The operating agreement states which structure applies and defines each role's authority.

Ohio does not legally require an LLC operating agreement, and you do not file it with the state - it is an internal document. But one is strongly recommended. Ohio's Revised Limited Liability Company Act (Ohio Revised Code Chapter 1706) fully recognizes the operating agreement and supplies default rules on management, voting, and profit sharing whenever an LLC has none. The only document you file to create the LLC is the Articles of Organization (Form 610, $99).

Quick Answer

Required by Ohio?: No - not legally required
Filed with the state?: No - kept as an internal record
Governing law: Ohio Revised Code Chapter 1706
Default management: Member-managed unless you choose otherwise
Recommended for: Single-member and multi-member LLCs
Formation document: Articles of Organization (Form 610, $99)

Is an Operating Agreement Required in Ohio?

No Ohio statute forces an LLC to adopt an operating agreement. You can form a valid Ohio LLC by filing the Articles of Organization (Form 610) alone. That said, "not required" is not the same as "not needed." Ohio's Revised Limited Liability Company Act, codified at Ohio Revised Code Chapter 1706, is built around the operating agreement: it repeatedly lets the agreement override statutory defaults, so an LLC without one is simply governed entirely by the state's off-the-shelf rules.

For that reason, an operating agreement is strongly recommended for every Ohio LLC, whether single-member or multi-member. It is the document that lets the owners, rather than the legislature, decide how the business runs. For the national picture of what these agreements do, see the operating agreement hub, and to see where it fits in setup, how to form an LLC in Ohio.

You Do Not File It With the State

An Ohio operating agreement is a private, internal contract among the members. You do not submit it to the Ohio Secretary of State, and the state does not keep a copy. The only formation document the Secretary of State receives is the Articles of Organization. You keep the signed operating agreement with your company records, alongside your EIN confirmation and formation paperwork.

Even though it is never filed, third parties often ask to see it. Banks commonly request the operating agreement when you open a business account, and investors, lenders, and potential buyers review it during due diligence. A single-member owner may also be asked for it to confirm authority to act for the LLC.

Why an Ohio LLC Should Have One

The operating agreement does several jobs the Articles of Organization cannot. It sets ownership percentages, defines how profits and losses are split, establishes voting rights, and spells out what happens when a member leaves, dies, or wants to sell. Without it, the Chapter 1706 defaults apply, and those defaults may not reflect the members' actual deal.

For a single-member LLC, the agreement reinforces that the business is a separate entity from its owner, which helps preserve the limited liability protection the LLC exists to provide. For a multi-member LLC, it is essential dispute-prevention infrastructure: a clear, signed agreement resolves questions before they become conflicts. Compare LLC vs. corporation governance if you are still choosing a structure.

Member-Managed vs. Manager-Managed

A key decision the operating agreement records is the management structure. By default under Ohio Revised Code Chapter 1706, an Ohio LLC is member-managed, meaning the members themselves run day-to-day operations and each generally has authority to act for the company. Alternatively, you can choose a manager-managed structure, in which the members appoint one or more managers - who may or may not be members - to handle operations while the members take a more passive, investor-like role.

The choice matters for authority and liability. In a manager-managed LLC, non-manager members typically cannot bind the company, which suits passive investors. The operating agreement states which structure applies and defines each role's powers, limits, and removal process. Whichever you pick, keep it consistent with how you describe the LLC elsewhere, including to your statutory agent and bank.

What to Include in an Ohio Operating Agreement

A thorough Ohio operating agreement covers the following. Each item lets you displace a Chapter 1706 default with your own rule.

Company basics: LLC name, principal office, statutory agent, and purpose.
Members and ownership: each member's name, capital contribution, and membership (ownership) percentage.
Management: member-managed or manager-managed, and the authority of each.
Voting: how votes are allocated and what threshold major decisions require.
Profits and distributions: how and when profits and losses are allocated and distributed.
Transfers: rules for admitting new members and transferring or selling a membership interest.
Withdrawal and dissociation: what happens when a member leaves, dies, or becomes incapacitated.
Dissolution: how the LLC winds up, cross-referencing Ohio dissolution steps.
Tax treatment: the default or elected classification; see Ohio LLC tax filing.

Ohio's Default Rules Under Chapter 1706

When an operating agreement is silent or does not exist, Ohio Revised Code Chapter 1706 fills the gaps. The statute sets default rules on management (member-managed), the effect and enforceability of the operating agreement (Section 1706.08), voting, distributions, and members' rights and duties. These defaults are functional, but they are one-size-fits-all and can produce results the members did not intend - for example, on how profits are split relative to unequal contributions.

Chapter 1706 also draws limits on what an operating agreement can do. Certain provisions - such as eliminating the duty of good faith and fair dealing entirely - cannot be waived, and the statute controls where the agreement would cross those lines. A well-drafted agreement works within Chapter 1706 to customize the parts you can control while respecting the parts you cannot.

Single-Member vs. Multi-Member Considerations

A single-member Ohio LLC agreement is short but valuable: it documents that the owner and the LLC are distinct, records the initial capital contribution, and names a successor or transfer plan. This separation supports the liability shield and answers the bank's request for governing documents.

A multi-member agreement is more involved because it must reconcile several owners' expectations. Spell out contributions, ownership splits, decision thresholds, deadlock-breaking mechanisms, and buy-sell terms. These provisions are exactly what prevent expensive disputes later. Whether you have one member or several, adopt and sign the agreement early, then update it whenever ownership or management changes.

How to Create and Adopt Your Ohio Operating Agreement

Creating an Ohio operating agreement is a straightforward, internal process because the state is not involved. Start after your Articles of Organization are accepted, when you know the LLC exists and have your EIN. Draft the terms the members have agreed on, covering the items listed above, and make sure they are consistent with the management structure you described when forming the LLC. Because Ohio Revised Code Chapter 1706 lets the agreement override most defaults, the drafting stage is where you actually design how the company will run.

Once drafted, every member signs and dates the agreement, and each keeps a copy with the company records. There is no notarization or filing requirement in Ohio, though members may notarize signatures for extra formality. Store the signed original with your formation documents, statutory agent information, and bank paperwork so it is easy to produce when a bank or investor asks. Multi-member LLCs should also decide how the agreement can be amended - typically by a stated vote of the members - so future changes follow a clear process.

Finally, treat the agreement as a living document. Review it whenever ownership changes, a member joins or leaves, the management structure shifts, or the tax classification changes - for example, if the LLC later makes an S corporation election. An operating agreement that matches the LLC's current reality is far more useful in a dispute or sale than one that was signed at formation and never updated. Keeping it current is low-effort insurance against the exact conflicts the Chapter 1706 defaults were never designed to resolve for your specific business.
