Indiana does not use a "Certificate of Formation." The document that legally creates an Indiana LLC is the Articles of Organization, filed on State Form 49459 with the Indiana Secretary of State through the INBiz portal for $95 online or $100 by mail. It names your LLC, its registered agent, its management structure, and its organizer - and once the Secretary of State accepts it, the LLC exists.

"Certificate of Formation" vs Indiana's Articles of Organization

Many founders search for an "Indiana Certificate of Formation," but Indiana does not use that term. A Certificate of Formation is what states such as Texas, Delaware, and Washington call the document that creates an LLC. Indiana - like Florida, Illinois, and most states - calls the same document the Articles of Organization. The legal act is identical: filing the certificate creates the entity and starts its limited-liability shield. In Indiana the specific form is State Form 49459, and the rest of this page uses that exact name consistently. For the concept, see Articles of Organization and what is an LLC; for the full start-to-finish process, see how to form an LLC in Indiana.

Agency, Fee, and Filing Methods

You file the Articles of Organization with the Indiana Secretary of State, Business Services Division - not the Department of Revenue or a county. The filing fee is $95 when filed online through INBiz or $100 when filed on paper by mail. There are two ways to submit State Form 49459:

Online (INBiz): the fastest route, using the state's official business portal with a credit card. Online Articles are typically processed in about one business day.
By mail: send the signed State Form 49459 with a $100 check to the Secretary of State. Mailed filings generally take several business days plus mailing time.

Indiana does not charge a separate registered agent designation fee the way some states do, so the formation cost is the single filing fee. That fee is also the same whether the LLC will be single-member or multi-member, and whether it will be member-managed or manager-managed - the state does not price the filing by the number of owners. For a full breakdown of what an Indiana LLC costs beyond this one form, including the biennial report and any sales-tax registration, see Indiana LLC cost and the national how much an LLC costs. If you are still deciding whether an LLC is the right structure at all, compare it with a sole proprietorship before you file.

What State Form 49459 Requires, Line by Line

The Articles of Organization are a structured document. Each field collects specific information the Secretary of State needs to register your entity.

Field	What it asks
Entity name	The LLC name, including a required designator such as "LLC," "L.L.C.," or "Limited Liability Company," distinguishable in Secretary of State records
Principal office	The street address of the LLC's principal office
Registered agent & office	An individual Indiana resident or qualified entity who consents, plus a physical Indiana street address (no P.O. box alone)
Management	Whether the LLC is member-managed or manager-managed
Duration	Perpetual by default, or a stated period
Organizer	The name and signature of the person forming the LLC

The organizer signs and submits the Articles, and the organizer need not be a member of the LLC. Once the Secretary of State accepts the filing, you receive confirmation and can view the entity in the Indiana business entity search.

Choosing a Compliant Name

The name in your Articles must include an LLC designator and must be distinguishable on the records of the Secretary of State from existing entity names and reservations. Before you file, run an Indiana business entity search to confirm the name is not already taken. If you are not ready to file, you can reserve the name for 120 days through INBiz. A name that clears the state database can still infringe a federal trademark, so a separate trademark clearance is prudent for any brand you intend to build on. Naming rules for Indiana entities sit within IC 23-0.5-2.

The Registered Agent Requirement

Every Indiana LLC must name a registered agent in the Articles of Organization and maintain one continuously. Under IC 23-0.5-4-1, the agent receives service of process and official notices at a physical Indiana registered office. The agent must be an individual Indiana resident or a domestic or qualified foreign entity, and must consent to serve. You may act as your own agent, name a manager, or hire a commercial registered agent service. To change the agent later, file a Statement of Change of Registered Agent through INBiz. Failing to maintain an agent is independent grounds for administrative dissolution by the Secretary of State. See the national registered agent overview for more detail.

After the Articles Are Filed

Once the Secretary of State accepts State Form 49459, your LLC legally exists and appears in the public record. Three things typically come next:

Adopt an operating agreement. Indiana does not file it, but an operating agreement governs ownership, management, and profit distribution among members under IC 23-18.
Get an EIN. Apply for a free federal Employer Identification Number from the IRS to open a bank account and hire employees.
Register for Indiana taxes. Register with the Indiana Department of Revenue through INBiz for a Registered Retail Merchant Certificate (sales tax) and withholding if you have those obligations. See business licenses in Indiana.

Banks generally ask for the accepted Articles of Organization and the EIN to open a business account, so keep both records handy. It is also worth ordering a Certificate of Existence through INBiz if a lender, licensing board, or out-of-state registration requires proof that your LLC exists and is in good standing.

Common Filing Mistakes to Avoid

A handful of errors account for most rejected or problematic filings. The most frequent is a name that is not distinguishable from an existing entity - the Secretary of State will reject it, so search first with an Indiana business entity search. A second is naming a registered agent who has not actually consented to serve, or listing a registered office that is not a physical Indiana street address. A third is confusing member-managed and manager-managed structures; choose deliberately, because the choice determines who has authority to bind the LLC. Finally, do not treat the Articles of Organization as a substitute for the internal operating agreement - the two documents serve different functions, and skipping the agreement leaves your LLC governed entirely by the default rules in the Business Flexibility Act. A few minutes on each of these points before you submit saves a rejection and a re-filing.

Ongoing Obligations and Amendments

The Articles of Organization are a one-time filing, but two duties follow from it. First, Indiana requires a Business Entity Report - State Form 48725 - every two years, not annually, under IC 23-0.5-2-13. It is due in the anniversary month of formation and costs $32 online through INBiz or $50 by mail. Second, if the information in the Articles changes - the entity name, or a shift in management - you file Articles of Amendment with the Secretary of State through INBiz. When you eventually close the business, you file Articles of Dissolution (State Form 49465) after winding up; see how to dissolve an LLC in Indiana. Track report deadlines in the Indiana Business Entity Report guide.
