Why an Indiana Operating Agreement Matters
Indiana governs LLCs through the Business Flexibility Act at Indiana Code article 23-18, and the name is accurate. The Act supplies a workable default for almost every question and then steps aside wherever the members have agreed otherwise. It never requires an ordinary LLC to adopt an operating agreement.
There is one exception, and it is easy to miss. IC 23-18.1-4-1 states that a master limited liability company must have an operating agreement. If you are running a series structure in Indiana, the agreement is not optional and its contents are load-bearing.
Either way the document is private. The Secretary of State registers the company through INBiz, keeps the articles of organization and receives the business entity report. It has no form for an operating agreement, no place to upload one and no fee attached to one. Nothing about the agreement is ever filed.
Indiana counts by dollars, not by heads
This is the point most summaries get wrong. Under IC 23-18-4-3 the affirmative vote, approval or consent of a majority in interest of the members is required, and IC 23-18-1-13 defines a majority in interest as the members who have made more than fifty percent of the agreed value of the total contributions made by all members, to the extent those contributions have not been returned. Voting therefore follows money by default. Distributions do the same: IC 23-18-5-4 allocates them on the basis of the agreed value of each member's contributions where the operating agreement does not provide otherwise.
That default is friendlier to a funding member than the equal-shares rule most neighboring states use, and it is punishing for a member whose contribution was labor. A co-founder who built the business but put in $2,000 against a partner's $200,000 has, by default, one percent of the vote and one percent of the cash.
The single-member case in Indiana
A sole owner has no one to negotiate with, which is why the document gets skipped and why it still matters. An Indiana bank opening a business account asks for something that names the authorized signer. A lender underwriting equipment finance asks who may pledge assets. A buyer running diligence treats a missing agreement as an unpriced risk and adjusts the offer. And IC 23-18-4-4 makes clear that several useful protections, including modified duties and indemnification, come from a written agreement rather than from the Act. Background sits in the single-member LLC guide and the Indiana single-member LLC page.
What Article 23-18 Decides When You Say Nothing
| Question | Indiana answer with no agreement | Citation |
|---|---|---|
| Who decides | A majority in interest of the members | IC 23-18-4-3 |
| What a majority in interest means | More than half the agreed contribution value | IC 23-18-1-13 |
| Distributions | By agreed contribution value | IC 23-18-5-4 |
| Amending the agreement | Consent of all members | IC 23-18-4-3 |
| Manager management | Only if the articles of organization provide for managers | IC 23-18-4-3 |
| Personal creditor | Charging order conferring assignee rights only | IC 23-18-6-7 |
Why manager management has to be in the articles
IC 23-18-4-3 opens by looking at the articles of organization, not the operating agreement, for the manager question. An Indiana company that decides internally to appoint a manager but never amends its articles is still a member-managed company as far as the statute and any third party are concerned. If the plan is manager management, the change belongs in an amendment to the articles as well as in the agreement.
Contribution value is doing a lot of work
Both the voting default and the distribution default turn on the agreed value of contributions as stated in the records of the company. If those records are thin, informal or contradicted by an email, the default has nothing solid to operate on. Recording contributions and their agreed values is not bookkeeping tidiness in Indiana; it is the input to two statutory formulas.
Everyone has to agree to change the deal
IC 23-18-4-3 also requires the consent of all members to amend the operating agreement or to authorize action that contravenes it. A minority holder with one percent of the contribution value has no vote on ordinary business and an absolute veto on amendments. Companies that expect to bring in investors should decide early whether that is the balance they want.

Ten provisions do the heavy lifting in an Indiana company.
1. Members, percentages and the record of both
Name each member and state percentages. Then make sure the company's records reflect the agreed contribution values, because two statutory defaults read them.
2. Contributions, agreed values and later calls
Record cash, property and services with the value the members agreed. Say whether more can be demanded and what dilution follows a refusal.
3. Managers, and the matching articles change
If managers will run the company, the articles of organization must provide for them. The agreement then sets their authority, term and removal.
4. Vote counting and approval thresholds
Decide whether votes really should follow contribution value, then set which decisions need a supermajority and which still need everyone.
5. Allocations and distribution timing
If the intended split differs from contribution value, say so. Add a reserve and a tax distribution sized to the members pass-through liability.
6. Transfer controls and consent to admission
Set who may transfer, on what notice and at what price, and what consent turns an assignee into a member with a vote.
7. Admission, exit and the buyout price
Indiana does not price an exit for you. Fix the valuation method, the payment period and the treatment of a member who leaves badly.
8. Dissolution triggers and the payment order
Say what dissolves the company, who winds it up and how creditors and members are paid. Indiana dissolution covers the filing side.
9. Tax classification and who may change it
Record the federal classification and the consent needed to alter it. The IRS rules for LLCs follow the election, not the INBiz record.
10. Deadlock, disputes and amendment mechanics
Because amendments need unanimity by default, build the deadlock clause and the buy-sell trigger while everyone is still agreeable.

Series LLCs and the Agreement Indiana Insists On
Indiana puts its series rules in a separate article, IC 23-18.1, rather than inside the main LLC act. The structure works through a master limited liability company that designates series beneath it, and IC 23-18.1-4-1 states in one line that a master limited liability company must have an operating agreement. This is the only situation in this batch of states where the agreement is a legal precondition rather than a recommendation.
IC 23-18.1-5-1 then sets the conditions for a series to have liability separate from the master and from every other series. The operating agreement must so provide and must establish or provide for the establishment of the series. The records maintained for the series must account for the assets associated with it separately from the other assets. Notice of the limitation on liabilities of a series must appear in the articles of organization. And the master must file articles of designation for each series that is to have the protection.
All four have to hold at the same time. In practice the record condition is what fails: a single bank account, an insurance policy written in the master name, a lease signed without identifying the series. If you cannot say which series owns an asset from the records alone, the separation you are relying on does not exist.
What an Indiana Creditor Can Reach
IC 23-18-6-7 is short. On application by a judgment creditor of a member, a court with jurisdiction may charge the member's interest with payment of the unsatisfied judgment. To the extent charged, the creditor has only the rights of an assignee of that interest. The article does not deprive a member of the benefit of applicable exemption laws.
Notice what is absent. Indiana does not say the charging order is the exclusive remedy, as Kansas, Idaho, Iowa and Maine each do in terms. It also says nothing about foreclosure. That silence cuts both ways: there is no statutory foreclosure right for a creditor to invoke, and no statutory bar on a creditor arguing for other relief. Indiana LLC owners who assume they hold the strong exclusive-remedy protection sold in some states are relying on something their statute does not say.
Whether a sole member is treated differently
IC 23-18-6-7 does not distinguish by member count, so a single-member Indiana LLC gets exactly the same short provision. The practical protection is weaker, because an assignee of the only member's interest is entitled to everything the company distributes, and there is no second member whose vote could withhold distributions. Owners relying on the entity for asset protection should test that assumption honestly, and should keep the company current so nothing else is in dispute, which a certificate of existence demonstrates.
Duties, the Recklessness Standard and Written Modification
IC 23-18-4-2 sets a forgiving liability standard: a member or manager is not liable for acts or omissions in that capacity unless the conduct amounts to willful misconduct or recklessness. Alongside it sit real obligations. A member or manager must account to the company for any profit derived from a transaction connected with the company's business, hold confidential and proprietary information in trust for it, and avoid self-dealing without the consent of a majority of the disinterested members or managers. In a manager-managed company, a member who is not a manager owes no fiduciary duty to the company solely by being a member.
Almost all of that is subject to the phrase "unless otherwise provided in a written operating agreement", which is where the Business Flexibility Act earns its name. Indiana will let the members reallocate duties, expand or narrow indemnification and change the accounting obligation, provided they do it in writing. IC 23-18-4-4 confirms the point by listing what a written operating agreement may do, including modifying duties, providing indemnification and creating officer positions. An oral understanding does not reach any of it.
Three Indiana Companies and the Default That Applied
Example one: the founder who owned one percent of the vote
Wabash Machine Works LLC near Lafayette was formed by an engineer who contributed $3,000 and four years of design work, and an investor who contributed $290,000. They intended an even split of control. With no written agreement, IC 23-18-4-3 gave control to a majority in interest, and IC 23-18-1-13 measured that by contribution value, so the investor held roughly 99 percent of the vote. The engineer also received roughly one percent of a $180,000 distribution under IC 23-18-5-4, about $1,840 against an expected $90,000. One written clause would have set the split they actually agreed.
Example two: a series structure with one bank account
Monon Rental Holdings LLC in Indianapolis registered as a master LLC with five designated series, filed articles of designation for each and carried the required notice in its articles. Every rent check went into one account and the property insurance named only the master. After a $270,000 injury claim arising at one property, the claimant argued the conditions in IC 23-18.1-5-1 had never been satisfied because no records accounted for the assets of that series separately. The company settled at $190,000. Five accounts and a schedule of assets per series would have cost a few hundred dollars a year.
Example three: the manager who was never in the articles
A Fort Wayne logistics company appointed an outside manager by written consent of the members and gave him authority to sign leases. The articles of organization still said nothing about managers. When a landlord later challenged a disputed twelve-year lease, the company argued the manager had no authority, since IC 23-18-4-3 looks to the articles for the manager question. The dispute turned on a filing that would have taken twenty minutes. Keeping the registered agent and officer details current has the same logic behind it.
Five Mistakes Indiana LLCs Keep Making
Mistake 1: assuming equal shares because most states do it
Indiana is a contribution-value state for both voting and distributions. A template built around per-head equality gets the arithmetic backwards here.
Mistake 2: a sole owner treating it as optional paperwork
The audience is the bank, the lender, the insurer and the eventual buyer. Written indemnification under IC 23-18-4-4 is also unavailable without it.
Mistake 3: leaving contribution records vague
Two Indiana defaults read the agreed value of contributions from the company's records. Vague records make both defaults unpredictable.
Mistake 4: trying to file the agreement through INBiz
There is no field and no fee. What INBiz does take is the articles of organization, articles of designation for a series and the biennial business entity report.
Mistake 5: running a series or a manager without the matching filing
Series liability needs notice in the articles and articles of designation. Manager management needs the articles too. Internal paperwork alone does not reach third parties, and the same discipline applies to assumed business names.
What Happens When the Business Flexibility Act Decides
Indiana charges no penalty for the absence of an operating agreement and the Secretary of State never asks for one. Every cost is private, and each figure below is the price of a dispute rather than a fine.
The Lafayette founder lost roughly $88,000 of an expected distribution in one year, and the control of his own company, to a default he did not know existed. The Indianapolis series settlement was $190,000 for a record-keeping condition that the statute states in a single sentence. The Fort Wayne lease argument turned on a filing that costs a fraction of the legal fees spent debating it.
If these reach court, add ordinary commercial litigation costs. A contested claim among Indiana members that reaches discovery and a valuation fight commonly exceeds $75,000 per side in fees, and each side generally needs its own business appraisal, which for a small operating company runs roughly $10,000 to $25,000.
Quieter costs land first. A bank refuses the account because nobody can prove who signs. A lender declines or discounts. A buyer holds back part of the price. And a company preoccupied with an internal fight misses its biennial report and pays for reinstatement.
How File.Business Drafts Indiana Operating Agreements
We draft to IC 23-18 and, where a series is involved, to IC 23-18.1. The intake covers members, percentages and the contribution values that two Indiana defaults depend on, management structure with the matching articles language, voting thresholds, buyout terms, transfer controls, written duty and indemnification provisions under IC 23-18-4-4, and the federal tax election. Series clients get the agreement, the articles notice and the articles of designation treated as one package rather than three errands. Companies trading in other states get the agreement aligned with their foreign qualification. Changes that belong on the public record go through agent changes and article amendments.
Templates against drafted agreements
A template works for a one-member consultancy with a single account. It fails an Indiana company with unequal contributions, a manager, a series or an exit, because the Indiana defaults it needs to displace are not the ones a national form anticipates. General principles are in operating agreement essentials.
Indiana Operating Agreement FAQ
Does Indiana require an LLC to have an operating agreement?
Not for an ordinary LLC. The Business Flexibility Act supplies defaults instead. There is one exception: IC 23-18.1-4-1 provides that a master limited liability company, the vehicle used for series in Indiana, must have an operating agreement.
Does an Indiana operating agreement have to be in writing?
For the provisions that matter most, yes in practice. IC 23-18-4-3 defers to a written operating agreement, and IC 23-18-4-4 lists the things only a written operating agreement may do, including modifying duties, providing indemnification and creating officer positions.
Is the operating agreement filed with the Indiana Secretary of State?
No. INBiz has no field for it and no fee attaches to it, because it is an internal contract. The public filings are the articles of organization, any articles of designation for a series, and the biennial business entity report.
How does Indiana split profits with no agreement in place?
By contribution value. IC 23-18-5-4 allocates distributions on the basis of the agreed value, as stated in the company's records, of the contributions made by each member, to the extent received and not previously returned. It is not an equal-shares state.
What is a majority in interest of the members in Indiana?
IC 23-18-1-13 defines it as the members who have made more than fifty percent of the agreed value of the total contributions made by all members, to the extent those contributions have not been returned. Voting under IC 23-18-4-3 follows that measure by default.
What does an Indiana series LLC have to do to keep each series separate?
Four conditions in IC 23-18.1-5-1 must all hold: the operating agreement must provide for the limitation and establish the series, the records must account for that series assets separately, the articles of organization must carry notice of the limitation, and articles of designation must be filed for the series.
