Delaware Single-Member LLC Operating Agreement
Create a Delaware single-member LLC operating agreement with state-specific guidance on freedom-of-contract defaults, taxes, and liability protection.
Introduction
A single-member LLC operating agreement is the internal document where you, as the sole owner of a Delaware LLC, set the rules for how your business runs and how profits are handled. Delaware does not require the agreement to be in writing, or even signed, for it to bind you and the LLC, and the statute expressly says a single-member agreement is not unenforceable just because you are the only party to it. Delaware's Limited Liability Company Act is built around freedom of contract, letting your agreement override nearly all of the state's default rules, but writing it down is still the clearest evidence that you are running a real business rather than using the LLC as a personal wallet.
Key Things to Know
- 1
Delaware does not require an operating agreement to be in writing, oral or implied agreements are valid, and the statute says a single-member agreement is not unenforceable merely because there is only one party to it (6 Del. C. Section 18-101(9)).
- 2
Without an operating agreement, Delaware law allocates profits and losses based on the agreed value of each member's capital contribution, not split evenly (6 Del. C. Section 18-503).
- 3
A charging order is the exclusive remedy against a member's LLC interest in Delaware, and the statute says so explicitly whether the LLC has one member or more than one, a point Delaware added in 2013 partly in response to a Florida case that had gone the other way (6 Del. C. Section 18-703(d)).
- 4
Delaware LLCs owe a flat annual tax, currently billed at $300 for tax year 2025, but recently enacted House Bill 400 raises it to $400 for tax year 2026 and later, first payable June 1, 2027 (6 Del. C. Section 18-1107).
- 5
An operating agreement can expand, restrict, or fully eliminate a member's or manager's fiduciary duties. The one thing it can never eliminate is the implied covenant of good faith and fair dealing (6 Del. C. Section 18-1101(c)).
- 6
The operating agreement itself is not filed with the state. You form the LLC by filing a Certificate of Formation ($70 statutory fee) with the Delaware Division of Corporations, and you must maintain a Delaware registered agent.
- 7
Delaware LLCs do not file an annual report, unlike Delaware corporations. The only recurring state obligation for most LLCs is paying the annual tax described above.
Key decisions before you file
Before you file a LLC Operating Agreement in Delaware, a few decisions shape the document: which option to choose and what each one means. The LLC Operating Agreement guide walks through them.

Delaware Requirements for LLC Operating Agreement
It is the stated policy of the Delaware Limited Liability Company Act "to give the maximum effect to the principle of freedom of contract and to the enforceability of limited liability company agreements" (6 Del. C. Section 18-1101(b)). This Operating Agreement may accordingly modify, alter, or eliminate nearly all of the Act's default rules, a broader degree of override than most states' LLC statutes permit.
The fiduciary duties of Members and Managers may be expanded, restricted, or eliminated by provisions in this Operating Agreement, except that the implied contractual covenant of good faith and fair dealing may not be eliminated. The Agreement specifies the extent to which Members and Managers owe fiduciary duties to the LLC and to each other.
A Delaware LLC is member-managed by default unless the Operating Agreement provides for management by a manager. Unlike most states' per-member voting default, Delaware vests management in members in proportion to each member's percentage interest in the LLC's profits, with decisions controlled by members owning more than 50% of that interest, unless the Agreement provides otherwise (6 Del. C. Section 18-402).
Absent a contrary Operating Agreement provision, Delaware law allocates profits and losses on the basis of the agreed value, as stated in the Company's records, of each member's contributions, not split evenly among members. The Operating Agreement can set a different split (6 Del. C. Section 18-503).
Unless the Operating Agreement provides otherwise, an assignee of a member's LLC interest has no right to participate in management and does not become a member, even after acquiring the entire interest, except upon the vote or consent of all of the members (6 Del. C. Section 18-702). The Operating Agreement can lower or remove this consent requirement.
Unless the Operating Agreement provides otherwise, a member has no right to resign from a Delaware LLC before its dissolution and winding up. A right to withdraw before dissolution exists only if the Operating Agreement affirmatively creates one and states the events or timing that trigger it (6 Del. C. Section 18-603).
Unless the Operating Agreement sets a fixed term or other dissolution event, a Delaware LLC has perpetual existence. Absent a contrary provision, dissolution otherwise requires the vote of members owning more than two-thirds of the LLC's profits interest. For a single-member LLC, the death of the sole member is a dissolution event unless, within 90 days (or another period the Agreement sets), the member's personal representative agrees to continue the LLC and be admitted as a member (6 Del. C. Sections 18-801 and 18-804).
Delaware law authorizes the LLC to indemnify and hold harmless a member, manager, or other person "from and against any and all claims and demands whatsoever," subject only to whatever standards and restrictions the Operating Agreement itself sets (6 Del. C. Section 18-108). Unlike some states, the statute names no mandatory carve-outs, so the Operating Agreement is where any limits on indemnification, including any advancement of expenses, are actually defined.
A Delaware Operating Agreement may authorize certain actions, including amending the Agreement itself or creating a new class of membership interests, without the vote or approval of any member, if the Agreement so provides. Absent such a provision, Delaware's Act does not itself set a default amendment-voting threshold; the Agreement is where amendment procedures must be defined (6 Del. C. Section 18-302(a)).
An action to interpret, apply, or enforce the Operating Agreement, or the duties, rights, or obligations of members or managers, may be brought in the Delaware Court of Chancery, a specialized business court that decides cases without a jury (6 Del. C. Section 18-111). Many Delaware LLC agreements designate the Court of Chancery as the exclusive forum for this reason.
If establishing a Series LLC, the Operating Agreement must include specific provisions regarding the establishment of series, the segregation of assets and liabilities between series, and the management of each series. Delaware law provides specific requirements for Series LLCs that must be addressed in the Operating Agreement.
Unlike Delaware corporations, a Delaware LLC does not file an annual report. Its only recurring state filing obligation is a flat annual tax, currently billed at $300 for tax year 2025 and due by June 1 each year. Recently enacted legislation (House Bill 400, signed May 21, 2026) raises this tax to $400 for tax year 2026 and later, first payable June 1, 2027. The Operating Agreement should specify who is responsible for ensuring this tax is paid to keep the LLC in good standing.
Frequently Asked Questions
It's the internal document where a Delaware LLC's sole owner sets the rules for running the business and handling profits. Delaware doesn't require it to be written, and a single-member agreement is not unenforceable just because you're the only party to it. Putting it in writing is still the clearest proof the LLC is a real business.
Not by legal requirement. Delaware allows an oral or implied operating agreement, and it isn't subject to any statute of frauds (6 Del. C. Section 18-101(9)). But without a written one, state default rules fill every gap automatically, including a contribution-based profit split rather than one you choose yourself.
Delaware's default LLC rules fill the gap. Profits and losses get allocated based on the agreed value of each member's capital contribution rather than however you'd choose to split them, which matters most once you bring on a second member without defining your own split (6 Del. C. Section 18-503).
It supports that protection. Delaware law makes a charging order the exclusive remedy against your LLC interest, and the statute says so explicitly whether the LLC has one member or more than one, closing a gap some other states' courts have found in their own laws. Keeping LLC and personal finances separate still matters.
Delaware LLCs owe a flat annual tax, currently billed at $300 for tax year 2025, with no annual report required. Recently enacted House Bill 400 raises the tax to $400 starting with tax year 2026, first payable June 1, 2027, so budget for the increase going forward.
No. You file a Certificate of Formation ($70 statutory fee) with the Delaware Division of Corporations to form the LLC, but the operating agreement itself is an internal document you keep with your own records. It's never submitted to the state, and Delaware doesn't require it to even be signed to bind you.
Largely yes. Delaware lets an operating agreement expand, restrict, or fully eliminate the fiduciary duties a member or manager would otherwise owe, broader than many states allow. The one thing it can never eliminate is the implied covenant of good faith and fair dealing (6 Del. C. Section 18-1101(c)).
