How to Start an Indiana LLC: Step by Step

Your LLC name has to be distinguishable from the name of any other business of the same type already registered in Indiana. That is a legal test, not a gut feeling. INBiz spells out that business identifiers (Inc., LLC), articles (the, a, an), punctuation, capitalization, and hyphenation don't make a name distinguishable, so a near-copy will get your filing bounced.

Start at the Indiana business name search. Run your proposed name and a few close variations; the state suggests searching the singular form and trying both "and" and "&." If something already on file reads or sounds too similar, adjust before you file rather than after, because a rejection costs you days.

Naming rules to respect

• The name must include the words "Limited Liability Company" or an abbreviation of them, such as "LLC."
• It cannot imply the company is a government agency.
• Restricted words (those suggesting banking, trust, or insurance activity) need clearance from the relevant Indiana regulator before you can use them.
• It must be distinguishable from all active names in the Secretary of State's database.

Holding a name before you file

Not ready to file yet but worried someone will grab your name? Indiana lets you reserve an available name through INBiz for a $10 state fee. Reservation does not create the LLC; it just parks the name while you sort out the rest.

Before you can file the Articles of Organization, you need a registered agent lined up, because the agent is named right in the filing and the form includes a checkbox confirming the agent consented to the appointment.

Indiana requires every LLC to continuously maintain a registered agent and a registered office in Indiana for the life of the company, and P.O. boxes are not acceptable. This is the party that receives lawsuits, subpoenas, and official state notices on the LLC's behalf. Indiana classes agents as commercial (registered with the state and listed by name only) or noncommercial (listed with an Indiana street address).

Who can serve

• You: if you have an Indiana street address (not a P.O. box) where papers can be delivered. Your address then appears in the public record.
• Another individual: anyone with an Indiana street address, such as a co-owner, an employee, or an attorney.
• A commercial registered agent service: a business registered with the Secretary of State as a commercial agent. It keeps its own address on the public record instead of yours and has staff to accept documents.

The LLC itself is the one choice that's out. As the Secretary of State's FAQ puts it, a business cannot serve as its own registered agent.

Why the choice is not trivial

Whatever address you list as the registered agent shows up on Indiana's public business search, which anyone can pull up. Owners who would rather not have a home address indexed online usually go with a commercial service. If you travel or keep irregular hours, a service also means someone is there to take delivery of legal papers on the weeks you aren't.

The Articles of Organization is the document that brings your LLC into legal existence in Indiana. You file it through INBiz, the Secretary of State's online portal, signing in with an Access Indiana account. The state fee is $95 online ($100 on paper with State Form 49459), and INBiz adds a payment processing fee of at least $1 and no more than 2.15%; the INBiz fee calculator shows the current amounts.

Indiana doesn't publish a standard processing time or an expedite option for LLC formations, so file online and file early if you have a deadline. Once approved, the LLC shows up in Indiana's public database and your stamped documents become available.

What the Articles ask for

• LLC name: your full legal name with the required designator.
• Principal office address: the main business address. If the business is run remotely from a governing person's home, a 2026 checkbox lets you leave it blank and file State Form 9900382 instead, keeping the residence off the record.
• Registered agent: a commercial agent by name, or a noncommercial agent's name and Indiana street address, with an optional email for electronic service of process.
• Registered agent consent: a checkbox confirming the agent has consented to the appointment.
• Duration: perpetual, or a specific dissolution date.
• Management structure: whether the LLC is manager-managed, plus an optional single-member box.

What you leave out

You do not name your members, spell out ownership percentages, describe your line of business, or reveal any financials. The Articles are a short formation document. All the internal detail lives in your operating agreement, which stays private.

The operating agreement is your LLC's internal rulebook. Indiana neither requires you to file it nor puts it in any public database, but you want it settled before you take on partners, sign contracts, or open a bank account.

What a solid agreement covers

• Ownership: each member's name and percentage interest.
• Capital contributions: what everyone put in at the start and what future contributions may be required.
• Profit and loss allocation: how gains and losses split among members; usually tracks ownership but does not have to.
• Distributions: when and how cash actually gets paid out.
• Management: who runs the day-to-day, their authority, and which decisions require a full member vote.
• Voting: whether votes are weighted by ownership or counted per member.
• Transfers: what happens when a member wants to sell or exit, including rights of first refusal.
• Dissolution: how the company gets wound down and assets distributed.

For a single-member LLC, the agreement backs up your claim that the LLC is a real separate entity, something a court weighs if anyone tries to reach past the liability shield. For a multi-member LLC it is essential. Without it, Indiana's statutory defaults govern everything, and those defaults rarely mirror the deal the owners actually struck.

An Employer Identification Number is a nine-digit federal tax ID the IRS issues for free. Think of it as a Social Security number for the business. It goes on tax filings, bank applications, and payroll paperwork.

When you need one

• Your LLC has more than one member (multi-member LLCs file a partnership return and must have an EIN).
• You plan to hire employees.
• You want a business bank account (nearly every bank requires an EIN).
• You have elected S-corp or C-corp tax treatment.

A single-member LLC with no employees can technically use the owner's Social Security number for federal taxes, but most people get an EIN regardless. It keeps your SSN off business paperwork and makes opening an account cleaner.

How to apply

Complete the online application at the IRS EIN Assistant on IRS.gov. It takes about ten minutes, and if the application is approved, the number is issued on the spot, so you can print the confirmation and use it that day. Apply after Indiana approves your Articles. Online applications need a U.S. Social Security number or ITIN; applicants without one file Form SS-4 by fax or mail instead. If you form with Mainstay, we apply for the EIN for you as part of the package, and the number itself is free.

Keeping business and personal money apart is not optional if you want the liability protection to hold. Pay personal bills from the business account, or funnel business income through your personal checking, and you hand a court a reason to disregard the LLC entirely.

What banks usually want

• Your filed Articles of Organization from the Secretary of State
• Your IRS EIN confirmation letter
• Your operating agreement (many banks ask for it, so have it ready)
• Photo ID for everyone who will sign on the account

Indiana community banks and credit unions are often more flexible with brand-new LLCs than the big national chains, and several online business banks now open accounts without a branch visit. Compare monthly fees, transaction caps, and minimum balances before committing.

Most of the work is front-loaded at formation. After that, Indiana asks relatively little, but the little it asks is easy to forget because of its timing.

The biennial Business Entity Report

Indiana does not want a report every year. You file a Business Entity Report every two years through INBiz, and the first one is due two years after formation, by the end of your anniversary month. It costs $32 online ($50 on paper) and confirms your principal office, registered agent, and governing persons, with no financials. INBiz says there are no late fees, but an LLC that doesn't file is administratively dissolved after the state's pending-dissolution letter and deadline.

Registered agent upkeep and taxes

Your registered agent must stay reachable at an Indiana address throughout. If yours changes, file the update through INBiz; the paper Statement of Change (State Form 56367) has no filing fee. Separately, if you sell taxable goods or services you will register for sales tax with the Indiana Department of Revenue, and your pass-through profit is subject to Indiana's state and county income taxes on your personal return.

A simple compliance rhythm

Set a reminder for your report's anniversary month two years out, keep your registered agent information accurate, and keep business and personal finances strictly separate. Do those three things and an Indiana LLC is genuinely low-maintenance to run.
