Delaware LLC Operating Agreement: What It Is and Why You Need One

What is a Delaware LLC operating agreement?

A Delaware LLC operating agreement is a written contract among the members (owners) of the LLC that spells out how the company is owned, managed, and run. It is the LLC’s internal rulebook. Unlike the Certificate of Formation you file to create the entity, the operating agreement is never filed with Delaware and never reviewed by the state. It is a private document you keep in your own records.

Delaware’s LLC Act is built around the idea that members are free to arrange their affairs by contract — that freedom is one of the main reasons people form a Delaware LLC in the first place. The operating agreement is where you exercise that freedom. It can override most of Delaware’s default rules, so if you want anything other than the standard treatment — unequal profit splits, special voting rights, a buyout process — it has to be written here. If you write nothing, you simply inherit Delaware’s defaults, which may not match what you and your co-owners actually intended.

This guide is general information, not legal or tax advice. For complex ownership, vesting, or fundraising arrangements, have a Delaware business attorney review your agreement before you sign.

Do you have to file the operating agreement with Delaware?

No. This is the single most common point of confusion, so it is worth stating plainly: you do not file your operating agreement with the Delaware Division of Corporations, and there is no state fee for it. The only document Delaware files to bring your LLC into existence is the Certificate of Formation, which costs $110 and lists little more than your LLC’s name and registered agent.

Because the operating agreement is internal, it stays private. Your ownership percentages, profit splits, and management terms are not part of the public record. That privacy is a feature, not an oversight — it lets you keep sensitive ownership economics out of public view while still having an enforceable contract among the members. It also means you can amend the agreement whenever the members agree without paying Delaware anything or notifying the state. Compare this with your annual obligations: an LLC has no annual report, just the flat $300 franchise tax due June 1. The operating agreement sits entirely outside that state filing cycle.

Is a Delaware operating agreement legally required?

Delaware does not require you to file an operating agreement, and technically the Delaware LLC Act allows an agreement to be written, oral, or even implied by conduct. But that is a trap. Relying on an oral or implied agreement means that the moment there is a disagreement, nobody can prove what was agreed, and you fall back on Delaware’s default statutory rules. In practice, a written operating agreement is essential for every Delaware LLC, including one-person LLCs.

There are three reasons a written agreement is effectively mandatory in the real world, even though the statute is permissive. First, banks and payment processors ask for it before they open an account. Second, investors and acquirers demand it during due diligence. Third, it protects your limited liability by documenting that the LLC is a genuine separate entity rather than an extension of you personally. None of these are theoretical: they come up the first time you try to open a Mercury account or raise a dollar.

What does a Delaware LLC operating agreement cover?

A thorough operating agreement converts every important assumption into a written rule. The core sections almost every Delaware LLC agreement should include are:

• Ownership (membership interests). Who the members are and what percentage each owns. This is the heart of the document — it defines who owns what.
• Capital contributions. What each member put in, whether cash, property, equipment, or services, and whether more can be required later.
• Management structure. Whether the LLC is member-managed (owners run it) or manager-managed (appointed managers run it), and who has authority to bind the company.
• Profit and loss distributions. How money is split — by ownership percentage or some other formula — and when distributions are paid.
• Voting rights. What decisions need a vote and what threshold (majority, supermajority, unanimous) each requires.
• Transfers and exits. How a member can sell or transfer their interest, rights of first refusal, and what happens on death, withdrawal, or buyout.
• Dissolution. The process and triggers for winding down and closing the LLC.

The exact mix depends on your situation. A solo founder needs a short, clean agreement; a four-person startup heading toward a C-Corp conversion needs vesting, transfer restrictions, and carefully drafted voting terms. The operating-agreement template we include with formation is structured to cover the standard sections above and then be expanded by an attorney if your situation calls for it.

Single-member vs multi-member: how do they differ?

The structure of your operating agreement changes meaningfully depending on how many owners the LLC has. A single-member agreement is mostly about proving the entity is separate and recording who controls it. A multi-member agreement is a genuine contract among co-owners that has to anticipate disagreement, exits, and unequal contributions.

Note the tax row. By default the IRS treats a single-member LLC as a disregarded entity and a multi-member LLC as a partnership. Foreign-owned single-member LLCs carry an extra federal obligation regardless of how the operating agreement reads: they must file Form 5472 with a pro-forma Form 1120, and the penalty for missing it is $25,000. The operating agreement records the ownership economics; it does not replace those filings.

Why do single-member LLCs still need an operating agreement?

It feels redundant to write a contract with yourself, but a single-member operating agreement does real work. Its most important job is reinforcing the liability shield. The whole point of an LLC is that the company is legally separate from you, so business debts and lawsuits stop at the company. A written operating agreement is evidence of that separation. Without one, a creditor arguing that you and the LLC are really the same thing — known as piercing the veil — has an easier time.

The second job is practical: banks require it. When a solo or non-resident founder applies to Mercury, Wise, Relay, or a traditional US bank, the operating agreement is one of the documents the bank reviews to confirm who owns and controls the account. Founders forming through our non-resident service consistently find that the operating agreement, the Certificate of Formation, and the EIN are the three documents banks ask for together. Skipping the operating agreement to save time usually backfires the week you try to open an account.

Why do banks and investors ask to see it?

Banks operate under know-your-customer and anti-money-laundering rules that require them to identify the real owners and controllers of every account. The operating agreement is the single document that maps that out: it names the members, their percentages, and who has signing authority. A Certificate of Formation alone does not show ownership percentages, which is exactly why the bank also wants the agreement.

Investors and acquirers ask for it for a different reason: due diligence. Before anyone puts money in or buys the company, they need to confirm who actually owns it, whether there are competing claims, how decisions get made, and whether interests transfer cleanly. A sloppy or missing operating agreement is a red flag that can slow or kill a deal. If your long-term plan is venture funding, you will likely convert the LLC to a C-Corp first, and a clean operating agreement makes that conversion far less painful.

How do you create a Delaware LLC operating agreement, step by step?

The process is straightforward once you know the building blocks. Here is the sequence we use when preparing an agreement during formation:

Step 1 — Confirm your structure. Decide if the LLC is single-member or multi-member, and whether it will be member-managed or manager-managed. Everything downstream depends on this.

Step 2 — List ownership and contributions. Record every member, their ownership percentage, and what each contributed. Be precise: ambiguity here is where future disputes begin.

Step 3 — Set management and voting rules. Define who can act for the company and what level of approval each kind of decision needs, from routine spending to selling the business.

Step 4 — Define distributions. State how profits and losses are allocated and when distributions are made. For a single member this is trivial; for multiple members it is one of the most negotiated sections.

Step 5 — Add transfer and exit terms. Cover how members sell or transfer interests, rights of first refusal, and what happens on death, withdrawal, or dissolution.

Step 6 — Sign and store. Have all members sign, keep the signed copy with your records, and have it ready when you open your bank account. You do not send it anywhere in the state.

You can see how this fits into the overall formation flow on our how it works page, where the operating agreement is delivered alongside the state filing and EIN.

What does a Delaware operating agreement cost?

The operating agreement itself has no state fee because you never file it with Delaware. Your costs come from how you produce it. A do-it-yourself template is free but may miss provisions you actually need. An attorney-drafted agreement for a complex multi-member or investor-ready LLC can run from a few hundred to a few thousand dollars depending on complexity — verify current rates with the attorney.

With our service the agreement is bundled, so there is no separate line item. For the full breakdown of what formation and ongoing maintenance cost — including the Year 2 $300 franchise tax and ~$99 registered agent renewal — see our Delaware LLC cost page and pricing.

What happens if you do not have one?

Without an operating agreement, your LLC is governed entirely by Delaware’s default statutory rules, and those defaults rarely match what founders assume. For a multi-member LLC, that can mean profits or voting power are split in ways you never agreed to, any member may be able to bind the company, and there is no defined process for buying someone out or handling a member’s departure. The first serious disagreement among co-owners is when the absence of an agreement becomes expensive.

For a single-member LLC the immediate cost is more practical than legal: banks may decline or delay your account, and you lose a key piece of evidence supporting your liability shield. There is also a timing risk — if you try to assemble the agreement in a hurry the week a bank or investor asks, you make rushed decisions about ownership and management that are hard to unwind later. Drafting it calmly at formation, alongside your filing, avoids all of that.

What are the most common operating agreement mistakes?

A handful of errors account for most of the problems we see. The biggest is skipping it on a single-member LLC because it feels unnecessary — then scrambling when a bank asks. The second is relying on a verbal understanding among co-founders; friendships do not survive ambiguous equity splits, and Delaware’s law will not reconstruct what you meant to agree.

Other frequent mistakes: copying a template from the wrong state that cites another state’s statute; leaving out an exit or buyout clause, so there is no path when a member wants out; not matching the agreement to the EIN and tax treatment, which matters for foreign-owned LLCs that must file Form 5472; and never updating it after ownership changes, so the signed document no longer reflects reality. Because amendments cost nothing at the state level, there is no excuse to let the agreement drift out of date.

How does the operating agreement relate to the BOI / FinCEN report?

They are separate, and it is worth keeping them apart. The operating agreement is a private contract among members; Beneficial Ownership Information (BOI) reporting is a federal filing with FinCEN, not a Delaware state matter. Under a March 2025 FinCEN interim final rule, BOI reporting was removed for US domestic reporting companies, and US persons are generally exempt — only certain foreign reporting companies were left with an obligation. Because this area is still evolving, confirm the current requirement directly with FinCEN or a qualified advisor before assuming you do or do not need to file.

The practical link is that the same ownership facts your operating agreement records — who the members are and their percentages — are the facts a BOI report would draw on if one is required. Keeping a clean, current operating agreement makes any future reporting, whether BOI, banking KYC, or investor due diligence, far easier. Treat the operating agreement (internal) and any FinCEN obligation (federal) as two distinct items so neither gets confused with the other.

Worked example: a two-founder Delaware LLC

Suppose two founders form a Delaware LLC for a SaaS product. Founder A contributes $30,000 in cash; Founder B contributes the codebase and will work full-time. They agree on a 60/40 ownership split in B’s favor to reflect the full-time labor, with profits distributed by ownership percentage. They choose member-managed, require a unanimous vote to take on debt or sell the company, and add a buyout clause giving each founder a right of first refusal if the other wants to exit.

None of that is Delaware’s default. Without the operating agreement, Delaware would not know about the 60/40 split, the unanimous-vote threshold, or the buyout right — and a later dispute would be messy and expensive. With the agreement signed at formation, every important question already has an answer. If the company later raises venture money, the founders convert to a Delaware C-Corp, and the clean operating agreement makes that transition far smoother. This is exactly the kind of structure our formation service sets up at the start so it does not have to be reconstructed under pressure later.
