Indiana Single-Member LLC Operating Agreement
Create an Indiana single-member LLC operating agreement with state-specific guidance on Business Flexibility Act defaults, taxes, and liability protection.
Introduction
A single-member LLC operating agreement is the internal document where you, as the sole owner of an Indiana LLC, set the rules for how your business runs, how profits are handled, and what happens if you bring on a partner or close the business later. Indiana's Business Flexibility Act does not require an operating agreement to be in writing, oral or even implied agreements are legally binding, but written form is required to modify or eliminate the fiduciary duties and default liability protections members and managers otherwise have, and it is the clearest evidence, if a court or the IRS ever asks, that you are running a real business rather than using the LLC as a personal wallet.
Key Things to Know
- 1
Indiana law defines an operating agreement as any written or oral agreement among members, so a written document is not legally required in general, but written form is required to modify or eliminate fiduciary duties and default liability protections (Indiana Code Section 23-18-1-16; Section 23-18-4-4).
- 2
Without an operating agreement, Indiana law allocates profits and losses based on the agreed value of each member's capital contribution, not split evenly among members (Indiana Code Section 23-18-5-3).
- 3
A charging order lets a judgment creditor reach a member's distributions, but Indiana's charging-order statute does not itself say this is the creditor's exclusive remedy, unlike some other states' statutes, and the state's leading case did not resolve how single-member LLCs are treated (Indiana Code Section 23-18-6-7; Brant v. Krilich, 835 N.E.2d 582 (Ind. Ct. App. 2005)).
- 4
A member's promise to contribute cash, property, or services to the LLC is not enforceable unless that promise is in writing and signed by the member (Indiana Code Section 23-18-5-1).
- 5
Absent a written operating agreement, a member or manager is not liable to the LLC for actions taken on its behalf unless the conduct was willful misconduct or recklessness, and this standard can be modified or eliminated only in a written operating agreement (Indiana Code Section 23-18-4-2; Section 23-18-4-4).
- 6
Indiana LLCs do not pay an annual franchise tax. The recurring state obligation is a Business Entity Report, filed with the Secretary of State every two years, currently $32 online or $50 by mail (Indiana Code Section 23-0.5-2-13).
- 7
The operating agreement itself is not filed with the state. You form the LLC by filing Articles of Organization ($95 online, $100 by mail) through the Secretary of State's INBiz portal, and you must maintain a registered agent with an Indiana address (Indiana Code Section 23-18-2-4).
Key decisions before you file

Indiana Requirements for LLC Operating Agreement
A member-managed structure is the Indiana default: management of the LLC's business is vested in the members unless the Articles of Organization provide for a manager or managers (Indiana Code Section 23-18-4-1(a)). If the Articles elect manager-managed status, a manager must be designated or removed by a vote of a majority in interest of the members, unless a written Operating Agreement provides otherwise, and a manager need not be a member.
A member's promise to contribute cash, property, or services to the Company is not enforceable unless the promise is in writing and signed by the member (Indiana Code Section 23-18-5-1(a)). Absent a contrary written Operating Agreement provision, a member remains obligated to perform an enforceable contribution promise even if later unable to, including because of death or disability.
Absent a contrary Operating Agreement provision, Indiana 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 (Indiana Code Section 23-18-5-3).
Unless the Articles of Organization provide for a manager or managers, and except as a written Operating Agreement provides otherwise, ordinary business matters are decided by the affirmative vote of a majority in interest of the members. Amending the Operating Agreement, or authorizing an act that contravenes it, requires the consent of all members unless the Agreement lowers that threshold (Indiana Code Section 23-18-4-3).
Absent a written Operating Agreement, a member or manager is not liable to the Company for an action taken, or a failure to act, on the Company's behalf unless the conduct constitutes willful misconduct or recklessness, and each member or manager must account to the Company for any profit or benefit obtained without the consent of a majority of the disinterested members or managers (Indiana Code Section 23-18-4-2). A written Operating Agreement may modify, increase, decrease, limit, or eliminate these duties, including fiduciary duties (Indiana Code Section 23-18-4-4(a)(1)).
For an LLC formed after June 30, 1999, and unless the Operating Agreement provides otherwise, an assignee of a member's interest receives only the distributions the assignor would have received, and does not thereby gain management rights or become a member. Assigning an interest does not, by itself, release the assignor from liability as a member (Indiana Code Section 23-18-6-3.1).
A person acquiring an interest directly from the Company becomes a member upon complying with the Operating Agreement or, if the Agreement does not address admission in writing, upon the written consent of all members (Indiana Code Section 23-18-6-1(a)(1)). Admission is effective no earlier than the later of the Company's organization date or the time the Agreement, or the Company's records, provide.
Indiana law lists specific statutory events that end a person's membership, including voluntary withdrawal, removal by the Operating Agreement or a majority vote, a member's death, and dissolution of an entity member, among others (Indiana Code Section 23-18-6-5(a)). The Operating Agreement may add further triggering events, such as a member's insolvency, bankruptcy, or adjudicated incompetency (Section 23-18-6-5(b)).
For an LLC formed after June 30, 1999, dissolution occurs on the first of several events: those stated in writing in the Articles of Organization or Operating Agreement, judicial dissolution, or member consent. For an LLC formed after June 30, 2013, that consent must be unanimous unless the Operating Agreement lowers the threshold; for one formed between June 30, 1999 and July 1, 2013 with a single class of members, two-thirds in interest suffices (Indiana Code Section 23-18-9-1.1).
The Company must keep, at its principal office, a list of members and managers, its Articles of Organization and amendments, three years of tax returns and financial statements, and copies of any written Operating Agreements. A member may inspect and copy these records at the member's own expense during business hours after giving five business days' written notice (Indiana Code Section 23-18-4-8).
A written Operating Agreement may provide for indemnification of a member, manager, or other person against judgments, settlements, penalties, fines, or expenses incurred in a proceeding because of that person's status as a member or manager (Indiana Code Section 23-18-4-4(a)(2)). The Operating Agreement itself sets the standards and any limits on this indemnification.
Unless the Operating Agreement provides otherwise, amending the Operating Agreement requires the affirmative vote, approval, or consent of all members (Indiana Code Section 23-18-4-3(c)(1)). The Operating Agreement can lower this threshold for some or all amendments.
Indiana authorizes series LLCs under a separate article, Indiana Code Article 23-18.1, not the general Business Flexibility Act (Article 18) that governs this Agreement. A "series limited liability company" is a master LLC that has designated one or more series, each of which can hold its own assets and incur its own liabilities apart from the rest of the LLC. If establishing a series LLC, review Article 23-18.1's separate requirements in addition to this Agreement.
Frequently Asked Questions
It's the internal document where an Indiana LLC's sole owner sets the rules for running the business and handling profits. Indiana doesn't require it to be written, oral or implied agreements are binding, but written form is required to modify fiduciary duties, and it's the clearest proof the LLC is a real business, not just a personal wallet.
Not by legal requirement. Indiana's Business Flexibility Act allows an oral or implied operating agreement (Indiana Code Section 23-18-1-16). But without a written one, state default rules fill every gap automatically, including a contribution-based profit split rather than one you choose, and any change to fiduciary duties only takes effect in writing.
Indiana'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 (Indiana Code Section 23-18-5-3).
It supports that protection. Indiana law lets a judgment creditor obtain a charging order against a member's distributions, but the statute doesn't say this is the creditor's only remedy, and Indiana courts haven't clearly resolved how single-member LLCs are treated on this point. Following your agreement and keeping finances separate still matters.
Indiana LLCs don't pay an annual franchise tax. The recurring obligation is a Business Entity Report filed with the Secretary of State every two years, currently $32 online or $50 by mail, tied to the LLC's anniversary month (Indiana Code Section 23-0.5-2-13).
No. You file Articles of Organization ($95 online, $100 by mail) with the Indiana Secretary of State through the INBiz portal to form the LLC, but the operating agreement itself is an internal document. You keep it with your own records; it's never submitted to the state.
Largely yes. A written operating agreement can modify, increase, decrease, limit, or eliminate the duties, including fiduciary duties, that a member or manager would otherwise owe (Indiana Code Section 23-18-4-4). Absent a written agreement, the default standard already limits liability to willful misconduct or recklessness.
