Indiana LLC Operating Agreement: What to Include and Whether You Need One

An operating agreement is the document that sets out how your Indiana LLC actually runs: who owns what, who makes decisions, how money moves in and out, and what happens when an owner wants out. Indiana does not ask you to file one with the state. That makes the real question less about paperwork and more about what your bank, your lender, and your co-owners will expect.

This guide covers what the Indiana Secretary of State does and does not ask for, what a solid agreement contains, how a single-member LLC differs from a multi-member LLC in practice, and what to check before you use an indiana llc operating agreement template. This is informational content, not legal or tax advice. Confirm the points flagged below with an Indiana attorney or CPA before you rely on them.

Short Answer: Indiana Does Not Require a Filed Operating Agreement

Your LLC comes into existence when the state accepts the Articles of Organization. The Articles are State Form 49459, Articles of Organization, Domestic Limited Liability Company, and the filing fee is $95. The form and INBiz ask for four things: the LLC's name, its principal office, its registered agent, and whether it is manager-managed or member-managed. The form also has an optional single-member designation. The operating agreement is not part of that filing, and neither the form nor INBiz asks for a copy.

Form 49459 cites IC 23-18-2-4 and the Indiana Business Flexibility Act, IC 23-18, which governs Indiana LLCs. The Act is where the state's rules for LLC formation, management, and dissolution live, so it is the first place to look when you want to know what the default rules are.

State law also does not appear to require a written agreement. The Indiana Code definition of “operating agreement” in IC 23-18-1-16 is reported to include oral agreements among members. We read that definition in an IGA search excerpt, not on the full statute page, so treat it as unverified. Confirm the current text at iga.in.gov or with an attorney before you rely on it.

Even without a legal requirement, most banks and lenders ask for a written operating agreement when you open a business account or apply for a loan. Treat that as a practice point, not a statutory rule. In many cases the agreement is the document that shows the bank who is authorized to sign, and that alone makes it worth writing.

Why Write One Anyway

An operating agreement does three jobs that the state filing does not. It records the deal between the owners while everyone still agrees. It answers the questions that come up in disputes, such as who can bind the company to a contract or how a departing owner is paid. And it gives banks, lenders, and future buyers a single document to review instead of a verbal explanation.

The cost of skipping it shows up later. If two owners disagree about profit splits, or one wants to sell and the other does not, the dispute is harder to resolve without a written record. Writing the agreement at formation, when nobody is in conflict, is far cheaper than negotiating it after a disagreement starts.

Single-Member LLC: What the Agreement Still Does

A single-member LLC has one owner, so the agreement's job is different, but it still matters. For a solo owner, a written agreement typically covers who can sign for the business, which bank accounts belong to the company, how the business is valued if you sell it, and who takes over if you die or become unable to act.

Form 49459 includes an optional single-member designation. That designation is a line on the state form, not a substitute for an agreement. Whether Indiana's default rules for a single-member LLC change how these points work when no agreement exists is a question to confirm with an Indiana attorney. This guide does not state those defaults, because we could not verify them.

A single-member agreement is also where you can keep your personal and business affairs separate on paper. Recording that the LLC holds its own bank accounts, contracts, and records is a practical step, though it does not replace the advice of an attorney on how to protect your liability shield.

Multi-Member LLC: The Provisions That Matter Most

A multi-member LLC is where the operating agreement earns its keep. Most disputes between co-owners trace back to a handful of provisions. A solid agreement addresses each of them directly.

Ownership Percentages and Capital Contributions

State each owner's percentage interest and what that owner contributed to get it. Contributions can be cash, property, or services, and each type should be valued in writing. The agreement should also say whether owners must make additional contributions later, what happens if an owner does not contribute when asked, and whether a contribution changes the owner's percentage.

Management and Voting

Decide whether the LLC is manager-managed or member-managed. A member-managed LLC is run directly by its owners. A manager-managed LLC is run by one or more managers, who may or may not also be owners. Form 49459 asks you to choose, so the agreement should match the state filing.

Define how votes work. Specify which decisions need a simple majority and which need a higher threshold, such as selling substantially all assets, borrowing above a set amount, admitting a new owner, or amending the agreement itself. Name who has authority to sign contracts and open bank accounts. Ambiguity here is the most common source of expensive disagreements.

Distributions

Spell out how profit is distributed and when. Owners often assume distributions follow ownership percentages, but the agreement should say so. It should also address whether the company will hold back cash for operations, and whether distributions will be made at least often enough for owners to cover their tax bills on pass-through income. Indiana taxes an LLC's income at the owner level by default, so that timing matters. Discuss the mechanics with your CPA.

Transfer, Buy-Out, and Exit Terms

Decide what happens when an owner wants to leave, dies, becomes disabled, goes through a divorce, or files for bankruptcy. Common provisions include a right of first refusal, which lets the remaining owners buy a departing owner's interest before an outsider can. The agreement should also set out how the interest is valued, whether by formula, by appraisal, or by agreed figure, and the payment terms for a buy-out. Without these terms, a single owner's exit can stall the whole business.

Dissolution

List the events that trigger a wind-down, such as a vote of owners, the departure of a key member, or the completion of a stated project. Specify the voting threshold to dissolve, who handles the wind-down, and the order in which the company pays creditors and then distributes what remains to owners. The state's dissolution steps are separate from this internal process, so confirm them with an attorney before you file anything.

Choosing an Indiana Operating Agreement Template

Many owners start with an indiana operating agreement template because it is faster and cheaper than drafting from scratch. A template is a reasonable starting point. It is not a finished agreement. Before you use one, check these items:

• It refers to Indiana law, specifically IC 23-18, and not the LLC act of another state. Templates from other states cite different statutes and can conflict with Indiana rules.
• The management type matches what you entered on Form 49459.
• It fits your situation. A indiana single member llc agreement and an indiana multi member llc agreement cover different ground, so a single-member template will not handle buy-out or voting provisions for co-owners.
• Every blank is filled in or deliberately removed. Leftover brackets and default percentages cause real problems.
• All owners sign and date it, and the signed copy goes into your company records.

A template that looks complete can still hide terms that do not fit your business. Have an Indiana attorney review the final version, especially if there are multiple owners, outside investors, or a lender involved.

Filing and Tax Items That Connect to the Agreement

The operating agreement does not change your state filing obligations, but several of them should be reflected in it. The most important are these:

• Registered agent. Every Indiana business entity must continuously maintain a registered agent and registered office in Indiana. A business cannot serve as its own registered agent, and a P.O. Box is not sufficient for the registered office unless it comes with a rural route reference. Your agreement can say who manages this duty.
• Business Entity Report. The fee is $32, filed every other year by the end of the month in which the LLC was formed or registered. The first report is due two years after formation. A paper filing costs $50.
• Income tax. By default, an LLC's income passes through to its owners, who pay the individual adjusted gross income tax of 2.95% for 2026 plus their county local income tax. An LLC that elects corporate treatment pays the corporate adjusted gross income tax of 4.9% instead. Indiana has no franchise tax on LLCs. The agreement should reflect how income is allocated among owners. Confirm the details with a CPA and the Indiana Department of Revenue at in.gov/dor.
• Name reservation. If you need time to finish the agreement and the filing, you can reserve a name for 120 days for $10 through INBiz. The LLC name must include the words Limited Liability Company or an abbreviation of them.

Operating Agreement Checklist

1. Confirm your LLC name includes Limited Liability Company or an abbreviation, and that it is distinguishable from names already on the Secretary of State's records.
2. Choose manager-managed or member-managed before you file Form 49459.
3. Record each owner's percentage interest and capital contribution.
4. Define voting thresholds for ordinary and major decisions.
5. Set the distribution schedule and how profit is split.
6. Write the transfer, buy-out, and valuation terms.
7. List the dissolution triggers and the order of payments.
8. Name who can sign contracts and open bank accounts.
9. Have an Indiana attorney review the draft, and a CPA review the tax allocation.
10. Sign, date, and store the agreement with your company records.

When to Bring in a Professional

A single-member LLC with simple operations may be manageable with a careful template and a short review. A multi-member LLC, an LLC with outside investors, or any LLC that has a lender requirement should have an attorney draft or review the agreement. If you plan to elect corporate tax treatment, or if owners live in different states, bring in a CPA before the agreement is signed. The few hundred dollars a review costs is small compared with a dispute over who owns what.

The Indiana Small Business Development Center can also help you organize your plan before you meet with a professional. Its advisers do not replace an attorney, but they can help you list the decisions you need to make.
